Book: Pollution Science X - Florida - https://pollutionscience101Florida.blogspot.com
Michael
Ross from PollutionScience.com was doing an environmental survey report while investigating illegal wastewater
dumping from a beach storm drain off 2nd Avenue in Naples, Florida and
was illegally detained at this location on January 14th, 2024 at 1:30
am.
Michael Ross was investigating the illegal stormwater dumping
complaints when the police illegally raided his vehicle. The police
illegally searched the vehicle of Michael Ross by force and found an air rifle that
was not a true firearm. The authorities lied at first and said it was an
unidentified rifle instead of just saying it was an air rifle gun made
by Gamo, this was done in order to illegally detain Ross longer. The
authorities then lied right off the bat and said that Michael Ross had a
felony, the authorities then stated that it was illegal to own the air
rifle in the State of Florida because Ross had a previous felony. The fact is
that Michael Ross was never convicted of a felony in his life, and it is
legal for Michael Ross to own the air rifle. The authorities claimed
that it was illegal for felons to own an air rifle in the State of
Florida and that Ross was being detained for having an air rifle in his vehicle. Michael Ross was arrested for having an air rifle, Michael Ross will be filing a
lawsuit against this illegal detainment. Here is Ross's Driver's License
number (Texas Driver's License number: 18785123) (California Driver's
License: D8434672) (American Passport Id # 587031279) so that you can
see for yourselves that Michael Ross does not have a felony. These officials lied to
the public including other news agencies and claimed Ross had a felony
when Ross did not have a previous felony.
The government of Collier County had to create a
lie about Ross in order to stop his investigative journalism. The government lied to
the press and this is why you see the headlines that were claiming Ross was a felon that had an air rifle in his vehicle. The truth is
that Ross was never a convicted felon and it was legal for Ross to own the air
rifle. The police also claimed Ross was sleeping, when Ross claims he was not sleeping
and that he was just relaxing. There was a parking sign for the parking hours
but the sign was torn off the post, there was no way to tell the parking
hours, Ross was just enjoying the beach after visiting most of the
amusement parks in Florida for over two weeks. Ross was planning on
spending several months in Florida. For the records Ross checked the time
on my cellphone just 10 minutes before the illegal arrest. Ross was
planning on leaving the area at 2 am that night. We do not like how the
police tell multiple lies in front of journalists in order to falsify
more charges against people.
The problem is the Naples government
assumed Michael Ross had a previous felony because Ross was found with 2 grams of hash in
2009 in Texas, Ross received a reduced punishment down to a misdemeanor
instead of having a felony. The officials in Collier County, Florida
assumed it was a felony to have hash in Texas, these officials in
Florida lied and said Ross received a felony from having hash in Texas.
The truth is the charge was reduced to a misdemeanor and Ross never
received a felony. This is why even the media was lied to and you can
see in the headlines that the government misled the media, and why the
news article claims Ross was a felon in possession of an air rifle when it turns out that Michael Ross was never a convicted felon in his entire life. This makes it difficult to get more support from
others, this is because the public was lied to and thinks Ross was a
felon with an air rifle. It even makes it more difficult if Ross wanted to
find a job in the scientific community while the news headlines are
inaccurate and claim falsely that Ross was a felon. We believe that an AI
computer could have told the police by mistake that Ross had a felony. We
also see that the police removed all audio evidence of stating that Ross
was being arrested as being a felon with an air rifle.
You will
notice that the police arrested Ross first for trying to say that Ross was a
felon in possession of an air rifle, the police had no idea how
much cannabis hemp that Ross had at the time. Ross was originally detained first because
the police lied and said Ross was a felon in order to illegally arrest Ross.
The
police had to dismiss the case of Ross being a felon with an air rifle,
this is simply because Ross was never a felon and that Michael Ross was illegally
arrested. We consider this as an illegal attempt to try to gain illegal
access to his research van.
The Police refused to identify the
Gamo pellet gun as an air rifle and said that the rifle was an
unidentified rifle for multiple days. This was done in attempt to hold Ross in custody longer illegally. The police knew they made a mistake in
arresting Ross for having a pellet gun that was legal. The police wanted
to use the unidentified rifle as a distraction, this however kept Ross in
jail longer illegally and we will be seeking damages for this illegal
arrest.
We notice that the police did not even release the full
audio recording of the arrest of Michael Ross on 1/14/2014 at 1:30:10
am. We do not even see that the police were able to identify the air
rifle for a few days.
We also want to state that we believe why
it took longer to hear the charges. The police knew they made a mistake
and why it took longer for the police to figure out they illegally
arrested Ross for falsely saying that Ross was a felon with an
unidentified rifle, when Ross simply was not a felon with a rifle or an
air rifle. A jury will see multiple counts of tampering with evidence
and see that this evidence presented by these Collier County officials
was falsified. No honorable person would try to harm a scientific
researcher and medical researcher that has already had this much tainted
evidence and illegal detainment. The authorities are greedy and want the
money and silver, they don't care about our science research and
medical research.

The illegal arrest of Michael Ross - Background check to prove Michael Ross was never a felon.

Evidence Court Document - Evidence Exhibit A-4 & A-7 - Judge Krier:
Twentieth
District Court Judge Krier caused Libel, Slander and illegally signed
court documents that stated that Michael Ross is to be punished as a
previous felon, this was an illegal punishment and that Michael Ross was
never a previous felon. This judge attempted to give Michael James Ross extra
punishment from his illegal sentence and made the untrue statement that
Michael Ross was a previous felon. The truth is that Michael Ross was
never a felon. This Judge is trying to give Ross extra punishment and
time, this judge states that Michael Ross is a felon which is wrong. We
want this judge removed from office and to never be able to work as a
judge again.
The
Police illegally arrested Michael Ross and stated Ross was a previously convicted felon that
was found with an air rifle in his vehicle, the truth is that Michael Ross was never a felon. Mrs.
Gomes the District attorney lied and continued the extension of the illegal
arrest of Ross by saying Ross was to be tried as a convicted felon with an air
rifle, Mrs. Gomes also wanted to add additional punishments for falsely
stating that Ross was a previous felon as well. Judge Elizabeth Krier
(Respondeat superior) approved of Amira D. Fox and Nicole Santini of
adding additional punishments for Michael Ross. Fox, Gomes & Santini falsely
stated that Ross would receive more punishments for being a previous felon while
being illegally arrested.
The police wrongfully stated that Ross was being arrested as a felon in possession of an air rifle in his
vehicle. The truth is that the police did not tell the truth, Michael Ross was
never a convicted felon. The police then lied and said that Ross's Gamo air
rifle was an unidentified rifle to hold Ross in custody longer. Mrs. Gomes
lied in court and told the Judge and public that Ross was being charged as
a convicted felon with an air rifle. This statement was not true and
that Michael Ross was never a felon. The arrest of Michael James Ross
for having an air rifle was a form of either police error or intent to
illegally arrest scientific and medical journalist Michael Ross, we
consider this illegal arrest a form of police brutality. Judge Elizabeth
Krier approved of the illegal arrest of Michael Ross and allowed Amira
D. Fox and Nicole N. Santini to approve of additional punishments on Ross's punishment scoresheet. Additional points were added to Ross's
3.992(a) Criminal Punishment Code Scoresheet because Fox and Santini
stated that Ross was being punished as a previous felon. This also added more punishments on all other charges. We accuse these
authorities of illegally giving Michael James Ross more punishment
charges in attempt to silence political journalist Michael Ross. This
was done with malice, spite and with intent to illegally keep Michael
Ross longer in custody, and this caused harm to Michael Ross of
PollutionScience.com in different ways. We want Rhiannon Gomes, Amira Fox, Nicole Santini and Judge Elizabeth Krier to face arrest for tampering with evidence, this includes the libel, slander and contempt in court under oath. Rhiannon Gomes lied under oath and stated that Michael Ross was to be charged as a convicted felon with an air rifle. This created Judge Krier to increase the punishments of Michael Ross, simply because this made Judge Krier think that Ross's punishment should be more for being a previously convicted felon. Rhiannon Gomes tried to create malice to harm a member of the scientific community and the medical community.
Michael James Ross from
pollution Science is seeking 5 million dollars in damages for being
illegally arrested on January 14th, 2024 by Delia C. Luna and the
Collier County Police. Michael Ross is seeking an additional 6 million dollars for being held longer illegally in custody by Police Chief Kevin Rambosk. The authorities should have let Ross go with this
illegal arrest. The Young District Attorney Gomes did not properly check
and also wrongfully assumed that Michael Ross was a felon when Michael
Ross was not a felon. This mistake caused Michael Ross to spend multiple
days illegally detained, and this caused a lot of stress when having to
go to court to prove that Ross was never a felon. We want 7 million dollars
in additional damages for being illegally detained longer by young
District Attorney Rhiannon Gomes. May we remind the Jury what a Young
District Attorney is, this attorney has only been working as a District
Attorney since 2021. This Young attorney is not qualified to continue to
give illegal punishments to journalist Michael Ross of Pollution
Science. We want the Twentieth District Court Attorneys to stop issuing
more illegal punishments from continuing to state that Ross is a felon.
The authorities knew they made a mistake in illegally arresting Ross for
having an air rifle, the authorities then stated the air rifle was
unidentified for multiple days. The air rifle was in stock condition and
any competent officer could clearly see that it was a Gamo pellet gun
within one minute, the air rifle was unloaded and stored away out of public sight. The serial number and name of the air rifle was in no
way obstructed and could be identified within one minute or less. Amira
D. Fox and Nicole Santini also went along and took Young District
Attorney Mrs. Gomes's word that Ross was a felon and trusted her judgment
which was wrong. Fox and Santini tried to add additional punishment
points on the punishment scoresheet of Michael Ross and stated that Ross was a previous felon, this was
in attempt to give Ross more time on my charges because of this error.
Judge Elizabeth Krier approved of these documents as well that stated
Ross was a felon. Michael Ross is seeking Fourteen Million Dollars in
damages from Amira D. Fox. We are seeking Eight Million Dollars in
Damages from Nicole N. Santini, and we are seeking Twenty Million
dollars in Damages from Judge Elizabeth Krier.
My 4th Amendment
rights were violated, the police stated that I was being arrested as a
felon with an air rifle to gain access to my vehicle, I was never a
felon and this was an illegal arrest. My 2nd Amendment rights were
violated, I was illegally arrested for owning an air rifle. My 8th
Amendment rights were violated with cruel and unusual punishment, my
punishments were increased because the authorities claimed falsely I was
a felon. My 1st Amendment rights to peacefully gather were also
violated. My 13th Amendment rights were violated, the State of Florida is running a type of racketeering system in their prison systems to illegally extort money and wrongfully convict innocent citizens. These innocent citizens are then sent to private prison labor camps for profit.
Michael James Ross is also alleging libel, defamation,
slander, defamation per se, business disparagement, business defamation,
tortious interference with current and/or prospective business
relations, civil conspiracy and intentional infliction of emotional
distress caused by the authorities of Collier County, Florida. We need
to stop good researchers in the scientific community and medical
community from facing wrongful arrest and ask the authorities to please
stop this Vexatious litigation. These authorities have already lied and
stated Ross was a felon and this was not true. The original reason why Ross was being arrested is because the authorities stated that Ross was a previous felon in possession of an air rifle. We
consider this Vexatious litigation by the authorities of Collier County,
Florida if they continue to break the law to illegally arrest
reporters. The authorities have broken multiple laws and that if Michael Ross is illegally jailed for this, the public will know that Michael Ross from
PollutionScience.com is being jailed illegally. We consider this gross
negligence, Nonfeasance, Misfeasance, and acting with severe
recklessness with disregard for the safety or well-being of another
person by Collier County officials. This is happening while the
authorities lie to the public and tell the public that Michael Ross was a
felon in possession of an air-rifle, when the authorities made the
mistake and lied to the public about Ross being a felon. Michael Ross
was never a felon, and the Collier County Police officers made a mistake
in arresting Michael Ross for having an air rifle that was legal for
him to own. This was the first main cause for the authorities trying to
detain Ross, we want the audio recording from the Collier County Police
from 12 am to 3 am on the morning of the arrest on January 14th, 2024.
We are asking the public to stop this illegal detainment of Michael Ross
as a scientific journalist and medical journalist.
We accuse
Collier County Courtroom authorities of acting with scienter and that
these authorities were fully aware of what they were doing.
Scienter
refers to a person’s mental state at the time they allegedly committed a
crime. Specifically, scienter refers to whether the individual
intentionally and knowingly acted with the intent to defraud or
manipulate, or if the results of their actions were simply caused by a
mistake or accident. Scienter is a Latin term, which translates to
“knowledge.” Therefore, someone who acts with scienter is fully aware of
what they are doing and the consequences that can result, yet they go
ahead with it anyway.
This illegal arrest has caused me multiple
forms of personal injury, emotional stress, physical stress, headaches,
Libel and Slander. It is now more difficult to find work, this is a form
of Libel, Slander and this harms my public reputation as a scientific
journalist and medical journalist.
The police have stolen money I
wanted to use on fixing my teeth, I have had to put off fixing my teeth
until the authorities give me my stolen research funds back. I will now
have to sell my 3.25 acre property in Austin because of this
illegal arrest, I was going to turn this land into a storage rental
property. I have lost millions of dollars I was going to earn from
investing this money into my business. I have lost millions of dollars
because the authorities refuse to give me back my laptops with priceless
science, medical and COVID research. I have now lost millions in
research and accuse the Collier County authorities of harming
researchers in the scientific community and medical community. The
authorities attempted to edit out the audio that stated I was being
arrested as a previously convicted felon with an air rifle multiple times. This was done at
the time of my arrest and when I was being questioned sitting in my
vehicle. The authorities removed multiple audio clips that stated the
original reason of why I was being arrested and attempted to shift blame
to arrest me for cannabis that was not mine. The audio of Officer Delia
C. Luna was not shown in the evidence we received. Officer Delia C.
Luna stated that the first original reason why we were being arrested is
that we were a convicted felon with an air rifle. The police asked me
if I owned an air rifle while I was sitting in my vehicle, I stated that
I did have an air rifle in the vehicle. The police then stated for me
to step out of the vehicle, and within a minute the police stated that I
was being arrested for being a previous convicted felon in possession
of an air rifle. The authorities did not know how much cannabis or THC-A
legal hash that we had at the time. The audio of Troy A. Menning
stating that I was being arrested as a previous convicted felon with an
air rifle was deleted when I was being interviewed at the police
station. We see that the audio recording that the authorities gave my
lawyer had the section of audio taken out where Troy A. Menning stated
that I was being arrested as a felon with an air rifle. We accuse the
Collier County Police Department of trying to tamper with multiple forms
of evidence.
I bought the air rifle legally in Texas and did not
break any laws. Florida claims to try and be one of the more
conservative states, yet we see how they are trying to complain about
American citizens trying to own an Air Rifle. I remember in the 1990s
that any American could go into a store to buy an air rifle legally. I
will state for the record that I was never a felon and that I bought the
air rifle legally. I want the air rifle that was illegally confiscated
and stolen from me by the Collier County, Florida police department
back. I want all of my property back that was illegally confiscated.
The
Police Lied and said that we had a felony and that we were a felon in
possession of an air rifle. This was done to gain illegal access to
search our research vehicle to plant false evidence. We were clearly not
a felon and want all charges dismissed. I knew that I had an air rifle
but I was unaware that there was 9mm ammo, the vehicle was used by
multiple people and the van had not been cleaned. The air rifle was not
in plain sight and was in a box.
You will notice that the
authorities misspell the word paraphernalia in my charges and instead
use the word parapherna. We think that this must have been an auto spell
check error where the spell checker accidentally fills in the wrong
word and not the word you typed. This is another reason why we think
that an AI computer is behind some of these mistakes. I am starting to
think that it is the AI computer that is getting some people in trouble.
I
would like to know who has written this report, it appears that someone
replaced the word Paraphernalia with the word Parapherna. This was a
red flag because we believe an AI computer is doing a lot of this and
that some of these clerks are mostly letting the AI computers try and
write the report. Am I being charged with parapherna as a crime? I would
like these charges of Parapherna dropped and do not think that I
deserve the punishment for a crime that I did not commit.
May we remind the court what parapherna is.
Parapherna
- Definition: The property of a woman that on her marriage is not made a
part of her dower but remains her own and entirely free from the
control of the husband
Does the Twentieth District Court really wish to give Michael James Ross a misdemeanor for the crime of parapherna?
We refuse these charges and that the Collier County officials have multiple errors in their reports.
_______________________________
Court Document Evidence
Exhibit A-7 - Page 4: The Police knew that Ross had an Air Rifle and the police
stated that they found an air rifle within the first minutes of
searching the vehicle. The Police knew they illegally arrested Michael
Ross and this was a wrongful arrest. It turns out that Ross was never a
convicted felon and that Ross was illegally arrested for a crime that he
did not commit. The authorities then lied and stated that Ross was
being arrested for an unknown rifle to make the charge sound worse, this
was also done in an attempt to make it look as if Ross had a real
rifle. The following document states that Ross was arrested for an
unknown rifle.
Court Document Evidence
Exhibit A-7 - Page 5: The following Court document
states that Ross was being charged as a previous convicted felon in
possession of ammunition. This statement was false and this was an
illegal charge the authorities had to drop against Michael Ross.
You will notice that the authorities even state multiple times that Ross was being charged with a firearm as a convicted felon.

You will notice
that the other arresting police officers had to leave out that Ross was
being illegally arrested for an air rifle. We believe the arresting
police officers left out in their original reports that the first reason
why Michael Ross was being detained was for being an accused felon in
possession of an air rifle. Keep in mind that one of the first questions
the authorities asked Ross is if he had an air rifle. Michael Ross
replied truthfully to the officers and stated that he did own an air
rifle and felt that there was nothing wrong with owning a pellet gun in
America. Michael Ross told the truth to the authorities, we can see that
the authorities were dishonorable and lied on multiple occasions to
have journalist Michael James Ross illegally arrested. We want all of the arresting officers fired, we can clearly see that they lied to cover for each other in their reports. These officers are bad apples and we do not want them to continue to influence other officers to also be corrupt as the following officers. We no longer want the following officers to work as police officers. These officers failed to write in their reports that Michael Ross was being arrested as a previous convicted felon with an air rifle.
Delia C. Luna
Evan J. Scott
Anthony N. Iannuzzi
John Redhead
Yasmin M. Pachecho
Lynnze E. Bender
Leovijildo Rodriguez
Derrick Vazquez
Jake Crowther
We believe that most of the police officers understood and heard Officer Luna state that Michael Ross was being arrested in possession of an air rifle. It could be possible that the officers that were away from the van and standing on the beach may not have heard that Ross was being arrested for having an air rifle as a previously convicted felon. These were lies the Collier County Police Department made. We could like to prosecute the Collier County Police Department, Chief Rambosk and the officers that edited the video and audio footage of the illegal arrest of Michael Ross to faces charges of tampering with evidence. We also want an investigation into the corruption of many attorneys in Florida. Ross is seeking an additional 6 million dollars in damages from Police Chief Kevin Rambosk. Police Chief Rambosk acted illegally and decided to keep Ross illegally detained as a journalist. Ross is seeking an additional 30,000 Dollars for each day this illegal court trial goes on. We consider this a form of cruel and unusual punishment. Michael Ross was illegally arrested on January 14th, 2024, this illegal trial continues to go on even past August 2024.
The only way we will allow these officers back on the force is if they testify that Michael James Ross was illegally arrested. These officers must admit that Michael Ross was illegally arrested, and why they were told to not state that Ross was being arrested as a previous convicted felon with an air rifle.
_______________________________
The following is in relation to the Document titled "Court Document Evidence
Exhibit A-7 page 5" states the following.
The
court again created another lie and continued to state that Michael
Ross had a criminal history and was conducted to determine Ross was a
convicted felon. This again added more libel and slander to the good
name of Journalist Michael James Ross from PollutionScience.com.
This
report lied and stated that Ross had a criminal history of threatening a
Judge in Texas, Ross was never charged with threatening anyone, this
again is another lie that has now caused Michael Ross more harm, we consider this a
form of libel and slander. No wonder Judge Cohen was so upset about
this report, here is the following statement:
"A criminal history
was conducted to determine Ross was a convicted felon. Due to Ross
having an extensive criminal history, including threatening/ terrorizing
a judge in Texas, officer Luna is request Ross's bond be set by the
judge."
You will notice that officer Luna cannot even spell the
sentence right and should have used the word requesting instead of
request also. This statement also lied when it stated that Ross was a
convicted felon, this increased Ross's bond more since Ross was now being
treated as a past convicted felon instead of a non-felon.
Judge
Kyle Cohen said that the prosecuting attorney had written a very poorly
written report. We think Judge Kyle Cohen knew the authorities messed up with
the illegal arrest. At first we thought Judge Cohen
might be on our side, we now must question if Judge Kyle Cohen was being
bribed for continuing the case, or if this was a simple error that Ross
was being charged a previous felon with an air rifle that was overlooked. This evidence is
already tainted and I was never a felon with an Air rifle, this is what I
was originally being arrested for, this is what the News Articles
claim. I want the audio recordings of all the times I was told I was
being arrested as a felon with an rifle. It is not right that the Judge
allows this proceeding to continue with multiple sources of tainted
evidence. We wish for another District Court to hear this trial instead of the 20th District Court. The 20th District Court has tainted too much evidence and is not being honorable and honest with the evidence presented in this trial. The 20th District Court now has too much bias against Ross and has already broken too many laws to even hold a legal trial.
We now would like to file a complaint under the 28 U.S.
Code § 144 - Bias or prejudice of a judge against Judge Kyle Cohen,
Judge Elizabeth Krier and Judge John Mcgowan of the Twentieth District
Court in Collier County, Florida. We no longer think that these judges
are competent and want these judges to no longer have authority in any
further court cases to harm others as well. We want to know who else in
the 20th District Court that thinks this is acceptable to keep Michael
James Ross from PollutionScience.com in this illegal court trial still.
We will be filing a lawsuit against the next Judge in Collier
County for 30 million dollars if they wish to continue this illegal
case and continue to state that Ross should be punished as a previous felon.
The Police have stolen over 8,000$ and 4 boxes of American Silver Eagle Coins (Over 50,000$ in silver coins). These funds
were to be used to build a business to retire. I wanted to build a
Storage Container business on my property that was on 3 acres of land in Austin, there would be over One Hundred Storage Sheds. I am
now forced to sell my property because of this illegal arrest in Collier
County, Florida. I have lost millions of dollars in profit I could have
made with this money as an investment in my business.
Many
companies now think that I am a felon and that I wanted to get hired by a
science company even to do work. I have lost millions of dollars where I
could have been making over 400,000$ a year working with my research.
I
am unable to now work at these companies because they search my name
and see that I am a felon in the news articles. I have already written
some of these companies that the article stating that I am a felon is
not true.
I want to be compensated for my illegal arrest, I will use these funds for medical research and science research.
This
illegal arrest has cost me over 14,000$ in bail. This bail was set so
high because the authorities illegally gave me the bail of a previously convicted
felon, I want to be compensated for these financial losses.
I have spent over 1,000$ in towing fees, transportation and recovery to get my vehicle.
The
Police Damaged and smashed my Ep-500 Battery bank that was over 5,000$ , the police smashed this battery
on the ground, the police edited and removed this from the video.
We have spent over 10,000$ in legal fees and filing fees.
I am a Bronze Medalist in one of the 2019 National Sumo Wrestling tournaments, I will be filing a complaint with the Olympic committee and wrestling committee about my illegal arrest. The authorities have also cost me millions of dollars in contracts and endorsements I could have had with many wrestling and MMA organisations.

I have spent thousands of dollars in travel fees to travel from Texas to Florida for each court hearing.
We
have written a report on the environmental damage being caused by the
officials in Collier County, Florida. We will be filing an environmental
lawsuit against the State of Florida.
If the authorities want
to continue to illegally detain medical researchers in Florida, then we
must question if other science researchers and medical researchers are
having their medical research harmed in the state of Florida.
These
authorities do not care about our science research, they just want to
steal our science research funds and illegally detain journalists and
researchers.
We would like to state for the court records of how many complaints Judge Krier has against her. This judge has one of the lowest approval ratings out of any Judge in Florida. Let us see what other complaints have been filed against judge Elizabeth Krier and State Attorney Amira Fox.

https://thewashingtonstandard.com/the-next-tier-in-lee-county-florida-corruption-state-attorney-amira-fox/
I’ve been covering a story in Lee County, Florida which has uncovered a host of corruption related to the case of Deanna Williams in the judicial system, attorneys and the sheriff’s office. That has led to uncovering documents concerning the fraud the current sheriff, Carmine Marceno, has perpetrated on the people of the county and which the governor and attorney general are letting him get away with. There is still more to come on those both those stories as soon as I receive the documents I need to confirm several things. The next tier in the corruption is the state attorney for the 20th Judicial Circuit, Amira Fox.
According to Fox’s website:
Amira recognizes that the number one duty of a prosecutor is to keep the community safe. She and her husband Mike have raised four children in SW Florida and care deeply about the safety of our community. She understands that the worst criminals deserve the strongest sentences and believes that violent and habitual offenders must be severely punished. Recently, Amira worked to convict Mesac Damas, who murdered his wife and five children in Collier County and was successful in obtaining six death sentences. Amira has a long and distinguished record of convicting some of the most serious criminals in our five-county circuit since 1990.
Additionally, Amira has been instrumental in targeting those who commit crimes due to drug addiction and mental illness in order to hold them accountable while simultaneously seeking appropriate treatment so that they do not return to the criminal justice system. Thanks to the efforts of Amira, the Courts, local law enforcement, and local drug and mental health professionals, our area is a leader within Florida for its effective Drug Courts, Mental Health Courts and, Veteran’s Courts.
Finally, Amira believes that prosecutors must always look for new ways to attack crime and keep us safe. She has been instrumental over her last five years as Chief Assistant State Attorney in working with law enforcement to implement the gang and racketeering task force which has resulted in racketeering charges against gang members. She has also led the way in cooperating with law enforcement in conducting wiretap operations to catch and punish those who are selling and trafficking opioids and other illegal drugs in our community.
Now, a prosecutor’s number one duty is not to keep the community safe. It is to prosecute criminals. I grant that keeps the community safe, but when a woman like this is running around with a sheriff that has presented himself fraudulently, that is not keeping the community safe. It’s aiding and abetting.
Furthermore, I’ll be revealing just how Fox’s husband, Mike, is tied into the sordid injustice that Deanna Williams has suffered in a later article.
For today, I want to deal with just one case of the corruption of Amira Fox. The following two articles are posted in their entirety with permission from the author, along with links to the evidence of the complaint against her that she campaigned during working hours, which is a violation of law. Notice how despite the evidence, it was swept under the rug.

After calling FDLE for an update in January 2019, I spoke with two different FDLE Investigators who stated my two complaints on Amira Fox campaigning during work hours were mailed to the Department of State/ Division of Elections for investigation on November 2, 2018 and October 17, 2018.
Upon calling the Division of Elections I was informed they had no records of my complaints; I then resubmitted complaint #1 in late January.
Complaints #2 and #3, regarding the Illegal Slaughter farms were not found at FDLE and were thought to have been included with complaint #1 and sent to the Division of Elections. All documents appear to have been lost.

(Written complaint # 18-148; July 1st is a noted date typo, the correct date, July 5th, is documented in the four paged detailed spreadsheet of political events attended during work hours. It should be noted public records reveal Fox turned in a list of requested Leave dates from January 1, 2017 through July 31, 2018; however the details of the times for each request were not listed on the report, such as all day or half day, hours, etc. According to Fox’s timesheets she attended political events during work hours then took annual leave or sick leave after the political events were attended.
18-148 Original Complaints can be viewed below
It is the duty of the Florida Commission on Ethics to investigation all facts parties materially related to the complaint at issue. It appears the Florida Commission on Ethics did not fully investigate the overwhelming evidence presented in Complaint # 18-148 which revealed adequate reason to conduct an investigation beyond probable cause; nor were the direct witnesses provided to Investigator Travis Wade by both myself and complaint #17-164 contacted by Mr. Wade or Attorney General Advocate Elizabeth Miller.
(Opinion) It is concerning that Amira Fox, Russell’s Chief Assistant State Attorney cleared Pam Bondi in the Trump donation case without a proper investigation. Complainant Attorney Larrabee stated the decision by State Attorney Stephan Russell was flawed for not contacting him to conduct an investigation.Pam Bondi endorsed Amira Fox for State Attorney, Pam Bondi strongly supported Ashley Moody as her successor, now it appears we have an Attorney General Advocate (previous Bondi staffer) Elizabeth Miller dismissing Amira Fox’s alleged ethical violations without a proper investigation. Ashley Moody owes the citizens of Florida an explanation why there was not a proper and full investigation.

Notice, she was not cleared in this matter, the state simply didn’t investigate.
Just like the FDLE failed to do their due diligence in investigating Sheriff Carmine Marceno for clear ethics violations that should have gotten him removed from office and left a woman pregnant and her grand theft complaint of $200,000 ignored, it seems that Fox has the same connections in the State of Florida among those who simply don’t believe they should investigate this level of corruption.
And keep in mind, these are Republicans we’re talking about here.

Evidence Exhibit: iHeartRadio News
Iheart.com
is one of the largest radio broadcasting networks. It is a shame that iheart.com repeated the lie told by the officials Collier County,
Florida. iheart.com published an article in their headlines that states
"felon Found Asleep with 8,000$, Airsoft Rifle, and 98 Rounds of
Ammunition." I was never a felon to begin with and these lies that were
spread hurt me in many ways. This is why we are warning others in the
media to not trust what the officials in Collier County, Florida have to
say. We understand that it can be difficult for everyone in the media
to fact check to see who is a felon or not, especially when the
government of Collier County lies and announces to the press that
Michael Ross was a felon in possession of an air rifle. The media
agencies that repeat these lies being told will also be held
accountable. We are seeking damages for the harm that was caused through
libel and slander to Michael Ross from PollutionScience.com.
The
Police have illegally confiscated over 60,000$ of mine, I should have
gotten these funds back by now, instead the media has lied to the public
and stated I was a convicted felon with an air rifle, many people in
the public believed this lie. This lie that was spread is one of the
reasons why I was illegally detained longer also, and I should have
gotten back my money that was illegally confiscated by now. These funds
were to be used to build a business in Austin, Texas to retire. I wanted
to build a Storage business on my property that is over 3 acres of land
near downtown Austin, Texas. I am now forced to sell my property
because of this illegal arrest in Collier County, Florida. I have lost
millions of dollars in profit I could have made with this money as an
investment in my business.
It is now more difficult to find work
if I wanted. I wanted to get hired by a research company for medical
research or science research. It is difficult to find work at some of
these companies because of the headlines from I Heart Media Inc. that
stated I was a convicted felon with an air rifle in their headlines.
Some companies now think that I am a felon, I have lost millions in work
contracts from companies that would have hired me, these companies will
not hire someone they see in the news headlines that states they are a
felon being charged with crimes. I could have been making a lot of money
working for a research company, now it is more difficult to find work
because of the lies being spread by Collier County officials and the
media.
We consider this article written by I heart radio to not
be true, in fact this is a form of libel and slander. Michael Ross from
pollution science wishes to be compensated for these compensatory
damages, General Damages, Special Damages and Punitive Damages.
Michael
Ross is seeking 15 Million Dollars in damages from I heart Radio. We
are willing to settle out of court for less. We do not hate I heart
Radio, we could sue for several times more money but we are not greedy.
We do not want to hurt the trading stock of I Heart radio or any company
for that matter. We see the damages that I heart Radio caused from
having other media organisations repeat the lie that Michael Ross was a
felon. We have a list of damages in the text provided below.

Evidence Exhibit: MSN News Headline
The
Microsoft Network did not tell the truth in their published article
about researcher Michael Ross from PollutionScience.com. The article
stated that Michael Ross was a felon and this was not true. Michael Ross
was never a felon to begin with, MSN never properly checked to see if
Michael Ross was a felon or not before writing an article trying to say
that Michael Ross was a convicted felon. The article also stated that
Michael Ross was being arrested as a felon for being in possession of an
airsoft rifle in his vehicle. Michael Ross was never a convicted felon,
MSN had to delete the article because the article was not true and
caused a lot of harm to Michael Ross. We are seeking damages for the
harm that was caused through libel and slander to Michael Ross from
pollution Science.
We consider this gross negligence or
recklessness reporting. These reporters did not even identify that I was
the owner of the Pollution Science media agency.
The Microsoft Article states that Michael Ross was a felon being arrested with an airsoft rifle.
The
article assumed that I was a felon because it mirrored a report from iheart.com that said I was a felon. Both of these media agencies were
just
repeating the lie that the authorities told them, we do not
hate any media company for this. We tried to tell the authorities
several times ourselves that we were not felons. The problem I believe
is that an AI computer told the authorities I was a felon because I was
found with hash in 2009 in Texas, but I was given a misdemeanor instead
of a felony.
MSN caused Michael Ross harm, Libel and Slander,
this also is endangering my life and why I am having to go to court over
the police trying to illegally arrest me. Then these authorities with
the media both do not tell the truth to the public and say I was a felon
with an air-rifle. MSN helped continue the lie to hurt our chances of
why the public might not even want to now show up to the courthouse to
support us.
The Police lied and illegally confiscated over
60,000$ worth of money from Michael Ross. We believe that Michael Ross
could have been released from this illegal arrest, but that the media
repeated this lie that Ross was a felon, and this is why Ross could not
gain enough public support to be let free on an illegal arrest.
I
am unable to now work at these companies because they search my name
and see that I am a felon. I have already written to some of these
companies that the article stating that I am a felon is not true.
I want to be compensated for my illegal arrest, I will use these funds for medical research and science research.
We
cannot allow mainstream media to support the lies told against
scientific reporters to cause them this much harm. We need to stop these
illegal arrests of people in the scientific community and medical
community.
We can see here that there is clearly very little
respect for people in the scientific community. We want the Authorities
and the media to stop trying to tell the public that Michael Ross was a
felon with an airsoft rifle, BB gun, pellet gun or firearm. The lies have gone
too far now and have endangered our lives for being falsely thrown in
jail. We want this to never happen again to others, and why it is
unfortunate that we must take these authorities and media agencies to
court. Keep in mind that I could have sued MSN and other media agencies
for a lot more money than I am asking for. This is simply because I do
not want to cause harm to any business or try and take away too much
from the people that work for them. You must keep in mind the General
Damages, Special Damages and Punitive Damages. With all of the time we have
spent fighting this case, I could have made several more Pollution
Science books. I have to drive or fly from Texas to Florida for each
court case, this costs me thousands of dollars. I have had to pay over
10,000$ in attorney fees, and that I might not even be done with
attorney fees with the different wrongful arrest lawsuits I am filing.
It is going to cost me thousands to file these lawsuits, not to mention
the time and stress. Michael Ross is asking for a judgment of 12 million
dollars awarded to him from MSN.

Evidence Exhibit: Wink News (CBS)
Wink News (CBS) wrote in their article the following statement:
"Convicted
felon Michael Ross was arrested after he was found asleep in a van,
allegedly in possession of narcotics, over 8,000$ in cash, an airsoft
rifle and 98 rounds of ammunition."
However, Wink News was just
repeating this article and that this article did not say that I was a
felon in the main front headlines such as I heart Radio or MSN stated in
their news headlines.
This statement that Michael Ross is a
convicted Felon is not true, Michael Ross was never a convicted felon.
Wink News (CBS) did not do their full research. Wink News (CBS) should
have done their full research instead of listening to the lies of the
authorities in Collier County, Florida. Wink news circulated these
harmful lies that caused harm and damages as well as MSN. We do not hate
Wink News, I Heart Media or Microsoft News. We did not want these media
agencies to repeat this lie and that they never even stated what
scientific media organisation we are from. This media agency left out
that Michael Ross is the author of different Pollution Science books and
articles.
We consider this Libel and Slander.
I have lost
millions of dollars in jobs I could have taken as a researcher. I will
also have to now sell my home because of the money the Collier County
authorities illegally confiscated, this money was to build a business. I
was illegally arrested and detained even longer because the media
refused to help, and instead the media would spread the lies told by the
authorities in Collier County, Florida.
We are asking for 9
Million Dollars from Wink News (CBS) in compensatory damages, General
damages, Special damages and Punitive damages.

______________
We
bought our cannabis legally from the Greenhouse cannabis clinic in
Florida. We have had a medical cannabis prescription in California since
2006. You can even go to the website ( https://www.thegreeenhouse.com )
and call them up to see that they can legally sell multiple ounces of
cannabis. We would like to state that this is legal because of the Farm
Bill in 2018.
I bought THC-A hash which was legal. We think that
the authorities illegally gained access to our research quarters and
planted hash that was not ours to try and frame us to get us in trouble.
I
witnessed people smoking near the beach less than an hour from the
incident of my illegal arrest, I was not the only one on the beach.
Cannabis is also legal recreationally. I also had THC-A hemp concentrate
which is legal to buy. Many courts want to decide if that just because
someone has THC-A hemp cannabis that smells similar to real cannabis,
would this give the police to have probable cause to search the vehicle
that was parked. Some would say that just because an officer could smell
alcohol around a car that is parked, would this give officers the right
to search the vehicle. The officers never asked what type of cannabis
that I had when I was sitting in my vehicle. Keep in mind that I have
very important research and that this illegal search and seizure caused a
lot of good scientific research and medical research that was destroyed
on purpose by the Collier County Police Department. I accuse the
authorities of trying to plant more cannabis than I had, this includes
trying to plant hash that was not mine.
I had only around under 1
ounce of cannabis, I stated I had 20-22 grams or less. I thought at the most it could be around a little
over an ounce but not over 2 ounces. I stated that I knew the cannabis
was real cannabis. It can be difficult to judge because most of it was
leaf, I would say that maybe I had under one ounce of cannabis but was
not sure, this is why some people have a scale to check the weight. I
wanted to make sure that I also had a couple grams of THC-A hash that is
legal to have. I was asked about what type of hash it was and I was
told it was legal hash to have, I was told the hash was legal and that
it was THC-A. I accuse the authorities of planting false evidence and
the authorities added more cannabis than I originally had. I only had
THC-A hash which is legal, we accuse the authorities of trying to claim
that it was real hash and planted fake evidence to get me in trouble. The cannabis was in clear plastic containers with a medical label and barcode, everything was in legal cannabis container or recreational containers.
Report
Number: 24-0000468-002 lied and stated the following libel and slander.
The report first stated that Michael Ross was found with 1.15898 pounds
of cannabis (Court Document Evidence
Exhibit A-7 - Page 5), then the report changed later and
stated that Ross was found with 1.519 pounds of cannabis (Court Document Evidence
Exhibit A-7 -
Page 75). We see no record of the police stating they found extra
cannabis after their search. Officer Luna stated that the police found
1.15898 pounds of cannabis when the police completed their search of the
vehicle. The police then lied on Court Document Evidence
Exhibit A-7 - Page 13 that
states Ross was being charged with 1.519 pounds of cannabis.
Ross
claimed he had around 1 ounce or less or cannabis and that it was no
more than a quarter pound which is legal to carry in Florida. The police
claimed I first had 1.15898 Pounds, and now the police claim it was
1.519 lbs. I refuse these charges and believe the police lied about the
amount and type of cannabis in my vehicle. The Police gained access to
my vehicle with an illegal arrest and stated I was being arrested for
being a previous convicted felon in possession of an air rifle. The
truth is that Michael Ross was never a convicted felon and that Michael
Ross was wrongfully arrested by the Collier County Police on January
14th, 2024 at 1:30 am.
Court Document Evidence
Exhibit Evidence A-7 - Page 10 of 109: Officer Luna
states in her Report that Ross was arrested for 1.15898 lbs of
cannabis. We believe that this statement was a lie and that Ross never
had over 1 pound of cannabis. We see that in the evidence under Court Document Evidence
Exhibit
A-7 - Page 75 that states Ross was arrested for 1.519 Pounds of
cannabis. We see that these are two conflicting statements and that the
police first off lied and planted fake evidence to make it look like
that Michael Ross had over a pound of cannabis. We notice the Police lie
and said Ross was first found with 1.15898 pounds of cannabis, the
police later tried to increase the amount and lied, the police then lied
and said that Ross had 1.519 pounds of cannabis.
Page 49 states that Ross is being charged with 0.229 pounds (10.4 Grams) of THC oil and .01896 pounds (8.6 Grams) of THC wax.
Court Document Evidence
Exhibit A-7 - Page
5 stated that Ross was found with 0.1746 pounds of cannabis oil and
0.0326 Pounds of cannabis wax, we can see these are two conflicting
reports on the amount of weight that the Collier County Police claim
they found.
Court Document Evidence
Exhibit A-7 - Page 5: Officer Luna states that Ross was found with 1.15898 pounds of cannabis leaf.
Court Document Evidence
Exhibit A-7 - Page 75 states Ross was arrested for 1.519 Pounds of
cannabis leaf, again we can see these are two different conflicting
statements in the official police report.
Court Document Evidence
Exhibit A-7 Page 5 -
The authorities do not give a clear amount of hash that I was caught
with, the authorities either illegally planted hash in my car or created
a falsified police report. The police also had to change the amount
twice on the oil, wax and cannabis leaf. I never had oil or wax, I Had
legal THC-A hemp hash that was only around 1 gram that I stated. We
believe foul play was involved and that we see the police cannot get
their story straight on how much cannabis Ross had. The police lied and
even many years from now when this is said and done, I will have to tell
the public that the authorities framed me illegally and planted hash
there that was not mine.
The police state that I was found with
0.1746 Pounds of Cannabis Oil and 0.0326 pounds of cannabis wax. The
police try to make it look like we had a lot of cannabis hash that was
not ours. We would like for the Collier County Police Department to
explain the confusing numbering system to make it clear how much hash
that Ross was being charged with. Please explain what 0.0326 pounds is
in grams to the Jury and public. Please explain how much is 0.1746
pounds in grams that you claim you found. We want to know why the
officers lied about the weight of the hash that was illegally planted
and why the officers are trying to claim that this is a fraction of a
pound in hash. Ross claims to have legal THC-A hash and only to have
around a gram.
Court Document Evidence
Exhibit A-7 - Page 48: The Police then state Ross
had the following amount of Hash: THC oil (approximate weight 10.4
grams (0.0229 pounds), and THC wax (approximate weight 8.6 grams
(0.01896 pounds). We see a conflicting statement of Officer Luna on Court Document Evidence
Exhibit A7 - Page 5. We would like to know how .00326 pounds of
cannabis wax and 0.1746 pounds of cannabis oil was changed 3 different
times total. Court Document Evidence
Exhibit A7 - Page 48 states a completely different
amount. Not only did Officer Luna lie that Ross that was a felon
convicted of having an air rifle, it turns out that Ross was never a
felon, look at how many times we have had to repeat the statement that
Ross is not a felon to prove these lies were false.
We want to
know why Officer Luna and the police have multiple conflicting reports
about Ross being a convicted felon, this includes the air rifle the
police refused to identify for multiple days. We also want to know why
the police lied and framed Ross for being a convicted felon with an air
rifle, the police continued to not tell the truth to the public about the amount
of cannabis Ross had.
We believe the Police framed Michael Ross
in order to stop Ross with trying to publish more scientific journals
and medical journals. The Collier County Police continue to attempt to
get Ross in trouble, this was because Officer Luna knew she had already
lied about Ross being a convicted felon with an air rifle. This is why
Officer Luna attempted to lie even more, this was done with spite and to
attempt to give Ross more time for being detained on the illegal arrest
that officer Luna first created. This is why we clearly see that
Officer Luna already lied in her police report and that the weight she
claimed that was found was untrue, we can see that all of the police
reports about the illegal arrest of Michael James Ross have been
tainted. There is no way that Michael Ross ever had this much hash,
these are the most absurd charges. There is no way that I am carrying
around 18 grams of hash in my van. We are asking the public to please
stop the Collier County Officials from trying to lie and frame Michael
Ross for crimes that he did not commit. These are the same officials
that also lied about Ross being a felon with an air rifle.
Court Document Evidence
Exhibit A-7 - Page
108 states: ROSS admitted ownership of the marijuana found in his
vehicle but was not certain of the exact quantity. ROSS claimed he has a
medical marijuana card issued by the state of California and purchased
the marijuana and THC products from a delivery service in Orlando,
Florida called “Kovolo Cut-Off Collective”.
You will notice the
error in the police report that stated I did not show a medical cannabis
card and that I purchased from a delivery service in Orlando, Florida.
I showed the police my medical cannabis card, the cannabis card from Covelo cut-off Collective in California.
The Police got this statement wrong and stated that Covelo collective was a delivery service in Florida.
I
bought the cannabis leaf and cannabis THC-A hash in Florida, it is
legal to buy cannabis in Florida. My medical cannabis card was issued to
me in the State of California, The Covelo Collective in the State of
California issued me one of my cannabis licenses.
You can see for the record our Medical Documents under the Archive video titled Evidence Exhibit: Medical Documents (Michael Ross).
We also have proof that Ross purchased the Silver Coins in 2019. The Archive video titled Financial Statements (Michael Ross) proves that Ross bought these silver coins, these coins belong to Michael James Ross.

July 11th, 2024
https://archive.org/details/financial-statements-Ross
______________
Ross bought cannabis from The Green House TheGreeenHouse.com, Be Me Natural www.bemenatural.com/ and also other dispensaries.
The
Green House said that we can buy as much cannabis as we wanted. You can
go in the store and buy a pound of cannabis legally, the problem is
that another county such as Collier County tries to state that we had
over 20 grams which does not make sense. The problem is one county will
let you have multiple pounds of cannabis, while the next county over in
Collier County acts almost like a different country and changes the law.
Just because someone has a license to grow multiple pounds of cannabis in one state where it is legal, this does not mean those individuals are trying to sell that cannabis in other states illegally. Most people say that most other counties in Florida would not have
detained me for such a small amount of cannabis. We want to file a class
action lawsuit so that more people are not harmed by these draconian
laws, we consider this a form of entrapment. It isn't fair that I can
buy over a pound of medical cannabis legally in one county, while the
next county over is trying to say it is a felony to have a pound of
cannabis. I have a medical cannabis license in California. I had only
around 1 ounce of cannabis. I stated that I had around 20 grams of cannabis. It was not over 2 ounces. I told the authorities I was for
certain it was under 4 ounces, then the authorities claim it was 1.1
lbs, then the media claims it is 1.5 lbs. It isn't fair how I only had
around less thanan ounce of cannabis, then the media says I had a pound and a
half. I also had a couple grams of THC-A hash that is legal to have. I
accuse the authorities of planting false evidence and added more
cannabis than I originally had. I only had THC-A hash which is legal and
accuse the authorities of trying to claim that it was real hash and
planted fake evidence to get me in trouble. They stated why I had a
scale and multiple bags, and that the State of California stated it is
legal to have a scale or multiple bags, and that the State of Florida
must also recognize this. The scale was to weigh silver and to weigh
letters for the mail. So what if someone wants to keep a scale around to
at least know how much cannabis they have. You can also use a scale to
weigh how much cannabis to put in edible food. Keep in mind that you can
also eat over 1-4 ounces of cannabis in food, and why a pound of
cannabis might only last some people less than a couple months. I have
thrown in an ounce of cannabis in my meals in the past. We bought
cannabis in containers from the dispensary and that these containers do
not preserve the cannabis well, we wanted to put the cannabis in older medical containers that were still in medical jars and had the QR code. The QR code was starting to get worn out on some of the clear plastic bags with the medical cannabis logo and QR code. These were not in hard plastic containers for the medical cannabis. The cannabis bag with the QR code could be reused to seal the cannabis. We noticed that the police took the cannabis out of their original containers and destroyed the medical containers. We consider this another form of tampering with evidence. The police then tampered with audio evidence to make it look like the cannabis was not medical cannabis. All of the cannabis we had were in medical cannabis containers or recreational containers. The Police asked if I had medical containers and I stated yes, but I was not sure if they were medical containers or recreational containers. I bought the cannabis legally from different dispensaries and these containers had the QR code on them. You can see in the news pictures that
some of the cannabis we bought from the clinic was still in its original
packaging, yet this does not look like the cannabis that we had. I am not sure if those were the same THC-A hash containers,
we accuse the police of planting fake evidence to get us in trouble with
hash that was not ours. This cannabis also had a lot of leaves and why
it wasn't even that much cannabis to smoke. I would say that it could be
less than 20 grams of smokable material. It is difficult to judge the
amount of weight if the cannabis was mostly just leaf. I believe that I
should not be punished for having medical cannabis, and that I have a
medical cannabis prescription in California where it is even legal now
to grow cannabis for recreational use. It is not right that the
authorities threaten good researchers with so many years in prison for a
crime that I did not commit. I would like to state that the authorities
first lied and stated I was being charged as a previous felon in
possession of an air rifle, and that I was illegally given so much time
on my punishment scoresheet because the authorities are now trying to
say that I was a previous convicted felon. The police want to now lie
and state that I was a previous convicted felon to give me 15 years in
prison for what I consider was around 1 ounce of cannabis and legal
THC-A hash that I had around a gram of, but I did not have more than 2
grams of legal THC-A hash. We want the nightmare to end right now and
for the officials to finally stop this illegal detainment and punishment
against journalist Michael James Ross. I do not think it is fair to be
charged with this much punishment and time for under around an ounce of
cannabis that I had, this would include the 2 grams of hash that were
not mine. We consider 15 years cruel and unusual punishment for having
such a small amount of cannabis. The authorities illegally have given
Michael Ross 15 years of jail time for crimes he did not commit, this is
why Michael Ross was forced into filing a multi-million dollar lawsuit,
this is in order to stop this illegal arrest. We want the public to see
that the authorities have lied and tainted multiple sources of evidence
to harm Michael James Ross of PollutionScience.com. Any reasonable
court would have dismissed this already as a highly illegal case. This
is why I am confident that we will now be released from this illegal
arrest. We are going to please ask the court to release Michael James
Ross from this illegal arrest and these illegal court hearings.

{You
will notice that Brightgram had to remove the following article,
because the article is not true. However, the media was just repeating a
lie that the authorities told them. We never had a felony. It is sad
how people claim Florida is a conservative state. One of my friends
stated that Florida is just a trap for conservatives and that it is
actually one of the most corrupt states, I now understand what my friend
was saying. Florida is so corrupt that they tell some of their better
journalists and researchers that I cannot even own a BB gun, then create
lies to steal my science research funds. Then I have the authorities
forcing me to spend thousands of dollars on lawyers that I shouldn't
have to, this is a huge waste of my time. Keep in mind how we now see a
record number of lawyer billboard advertisements. I accuse the Naples
authorities of trying to ruin my science research, when you shouldn't be
harassing your better science and medical researchers over something so
petty. Would you harass other medical researchers such as Dr. Malone. I
want this to stop right now or we are going to order the military and
public to stop these corrupt officials abducting my media agency and
abducting journalists, scientists and researchers similar to the
Communist Pol Pot regime. We are now going to organize a writer's
strike. We refuse to finish our research on the Arctic and Antarctic
until the authorities give us back our property and money. Do you
understand how important this science research is. We do not like the
attitudes of these corrupt officials in Collier County, Florida. I doubt
most of them even read science publications. This is why the scientific
community is organizing for the arrests of these corrupt government
officials in Collier County, Florida until you stop trying to harass
Michael James Ross from Pollution Science.
These reports on the Arctic and Antarctic will be considered additional information for our report on the ocean and wind cycles of Florida stated in this article. We refuse to finish these scientific reports until the 20th District Court gives us our property, including our science and medical research funds back. We accuse the authorities in Collier County, Florida of trying to harm our media agency in order for us to stop our scientific reports and want the public to stop these corrupt government officials}.

Rhiannon Gomes, Judge Elizabeth Krier and Judge Kyle Cohen are a danger to the legal system, these Judges made a mistake and tried to give one of the best researchers in America 5 years in prison for claiming he was a felon with an air rifle. These judges are a danger to the scientific community and medical community. We want the Florida National Guard to shut-down Collier County, Florida under Martial Law.
We accuse these Judges of being in a similar type of Kids for Cash scandal. We clearly can see that these Judges were also helping pedophile rings such as Jeffery Epstein get away in Naples, Florida hotel rooms.
Bill Gates is connected to Jeffery Epstein in many ways. Why would Bill Gates want to spread some negative news article about Michael James Ross that was not true. We see that the mainstream media can decide who they choose to attack with untrue articles. Why is it that Bill Gates is connected with Epstein, then Microsoft News attempts to spread disinformation about a journalist attempting to stop many of these human trafficking rings that Bill Gates has ties to. This raises a giant red flag. Michael james Ross also has some of the top research in the county on COVID. We now must question if Microsoft news has bias against our COVID information. Is Microsoft News being used as a weapon to report disinformation about medical journalist and journalists from the scientific community?

'Arrest Bill Gates': Protesters Descend on Bill and Melinda Gates Foundation HQ
Jun 29, 2021
Protesters in London called for Bill Gates to be arrested on Saturday as they gathered outside the U.K. headquarters of the Bill & Melinda Gates Foundation as part of a larger protest against COVID-19 lockdown measures.
Videos circulating on social media on Tuesday appeared to show dozens of protesters outside the Gates Foundation's HQ in the British capital. They can be heard shouting "Arrest Bill Gates!" several times. Other social media users who were present at the protest also said demonstrators had been to the foundation's HQ on Saturday.
Gates, the founder of Microsoft and a multibillionaire, has been at the center of unfounded conspiracy theories involving the COVID-19 pandemic and the development of a vaccine.

We want Collier County, Florida Police Chief Kevin Rambosk to face arrest for tampering with audio and for human trafficking. We now see how the Collier County, Florida police tampered with audio evidence. The Police refused to release the audio and video footage of Michael Ross being told to step out of his car, and that the original reason why Michael James Ross was arrested was for the police claiming Ross was a convicted felon with an air rifle in his vehicle. This was a wrongful arrest. It is by law that an officer who arrests someone illegally needs to have their badge taken away and to also face arrest, this officer needs to now be arrested for the false arrest of a journalist. The Judges have failed to arrest any of these officers for an illegal arrest and for tampering with audio evidence. We clearly stated that all the cannabis was legal, we had under one ounce of cannabis, and for certain no more than a quarter pound. The Police changed their story multiple times about how much weight of cannabis that we had. The police also took the bag out of the containers we had the cannabis in and claimed they were not in medical containers. The Hash was legal THC-A hash that we bought from a cannabis dispensary in Florida.
The police tried to give Michael Ross 5 years in prison for claiming Ross was a convicted felon with an air rifle. These judges and District Attorneys of Collier County, Florida are a danger and we want these judges gavels taken away. We no longer believe that 20th District Court District Attorney Rhiannon Gomes is fit to continue to hand down illegal full 5 year prison sentences. How dare the 20th District Court of Collier County, Florida try to hand down these illegal sentences. We accuse the 20th District Court of Collier County, Florida of trying to terrorize their own researchers with illegal prison sentences and continue illegal trials of journalists. Judge Cohen is not fit to continue to hand down illegal prison sentences of 5 years in prison, then allow the District Attorney Rhiannon Gomes to continue an illegal trial to detain Michael Ross in jail longer for claiming he was a convicted felon with an air rifle. Michael Ross was thrown back in jail illegally, this happened the same hour when Rhiannon Gomes stated Ross was a felon with an air rifle and wanted to give Ross an illegal 5 year prison sentence. Ross was then illegally thrown back in jail while the police falsified audio and video evidence, then changed how much cannabis and hash Ross had multiple times. The police then planted bags of cannabis and hash that were not mine. Even the mainstream media lied about Michael Ross being a felon, including how the media claimed that Ross had 1.1 pounds of cannabis, to now 1.5 pounds of cannabis. The audio evidence was tampered with and I did not even state many of those these statements such as how all the cannabis was under one ounce and in medical containers, the police then stated it was over a quarter pound, to being over a pound. in the recording that my attorney was given.

You need to apologize to the public, your news company is a disgrace and had to remove your article that lied and stated Michael James Ross was a felon.

CBS news is now also guilty of helping this child kidnapping ring, in Collier County Florida . CBS will refuse to report on this and instead attack journalists trying to stop this human trafficking ring. CBS News promotes illegal immigrants invading America, and to create fake news stories about News journalists. We want to see the article where CBS now apologizes to Michael James Ross for lying that Ross is a felon with an air rifle. CBS is guilty of trying to lie to the public about journalist Michael James Ross. Notice how CBS refuses to apologize and write a correction on their fake story. We dare CBS to write another article that states Michael Ross is a convicted felon with an air rifle. PollutionScience.com is calling for a full boycott on CBS. We want CBS to stop the lies in their news articles that harm scientific journalists. CBS News is no better than a media agency being controlled under the Pol Pot regime. Notice CBS news lies about journalist Michael James Ross, CBS lied and stated Michael Ross was a felon that was arrested with an air rifle. CBS refuses to correct their article or apologize to Michael Ross. CBS has done all it can to harm America and the Nations of Europe. CBS wants for American culture and European culture to face cultural genocide from Third World refugees.

We now would like to file a complaint under the 28 U.S.

We are calling for the Florida National Guard and military to now arrest Judges Krier, Cohen and Mcgowan for tampering with evidence. We have disowned these judges, we will now disown the 20th District Court if the 20th District Court continues to harm scientific researchers and continues with the illegal arrest of Michael Ross. These judges are no longer to work in the legal system. These Judges are guilty of tampering with evidence, we want these Judges from the 20th District Court stopped right now. We want all of these Courtroom officials tried for treason and given the fullest possible punishment for treason. We no longer want the 20th District Court to have any authority in this case, the 20th District Court has broken too many laws. These Judges are a nuisance to the scientific community and medical community. These Judges are a nuisance to the scientific community. These authorities have had their chance to arrest Delia C. Luna for the wrongful arrest of Michael Ross. We consider this an obstruction of justice. The law requires that if a police officer wrongfully arrests a citizen for any reason, that this officer behind the wrongful arrest is now to be detained by law. Michael Ross was wrongfully arrested in January of 2024, it is now past August and the judges attempt to continue an illegal trial. We consider this a form of inhumane torture of a journalist. We are calling the Florida National Guard to arrest Collier County Police Officer Delia C. Luna and Collier County Police Chief Officer Rambosk.

Ethics complaint filed against Naples Mayor Teresa Heitmann
2021
https://winknews.com/2021/05/19/ethics-complaint-filed-against-naples-mayor-teresa-heitmann/
An
ethics complaint filed against the mayor of Naples is alleging
corruption at City Hall, including a child prostitution ring, involving
high-ranking leaders in Naples and Collier County.
The complaint
was written by Brian Dye, the director of technology services for the
City of Naples, to the Florida Commission on Ethics with a date of
Monday, May 17.
The 7-page complaint alleges that Mayor Teresa
Heitmann abused her position and office, directed Dye to break Sunshine
Laws and destroy public records and used her position for personal
gain...
The Collier County Sheriff’s Office referred it to the
Florida Department of Law Enforcement because through the complaint
Sheriff Kevin Rambosk learned Heitmann had accused Rambosk of running a
child prostitution ring at the Naples Municipal Airport with former
Naples Mayor Bill Barnett.
According to the complaint, the
Florida Department of Law Enforcement said Heitmann’s actions “were not
criminal enough to warrant their attention as the most they could
prosecute her for was a second-degree misdemeanor.”
They told Dye to take his concerns to the Florida Commission on Ethics.
As
for the allegations made against Rambosk, the sheriff said: “The
allegations made by Mayor Heitmann against me are untrue, irresponsible,
unethical and defamatory. These allegations made by a sitting elected
leader are outrageous...”

Lawsuit claims sex trafficking took place in more than 20 Collier County hotels
2023
COLLIER COUNTY — A new lawsuit, just filed in Collier County, shows a sex trafficking ring was operating in more than 20 different hotels for years.
Now, the victims are suing the hotel chains for $100 million in damages for not doing something about it. The brands named in the lawsuit include Best Western, La Quinta, Fairfield Inn, and Gulf Coast Inn.
“Our position is, basically, the hotels turned a blind eye. They knew, or they should have known, but it was an economic factor for them. These hotel rooms were being rented out,” said attorney Sharon Hanlon, who is representing the victims.
She said the hotels are at fault because the signs were unmistakable.
“Male traffickers were paying for the room with cash, and they would do it day by day, because they never knew when they were going to be raided on by the cops or anything,” said Hanlon.
And the lawsuit shows, in some cases, staff at the hotels didn’t just allow abuse, they joined in.

SWFL group ran human trafficking ring up, authorities say
March 06, 2015
A routine traffic stop by a Collier County sheriff’s deputy unraveled one of the largest human trafficking rings in Southwest Florida, leading to the arrests of 15 men and women Friday.
During a 2013 traffic stop, a deputy identified a woman as a potential victim. Detectives began an investigation and eventually identified a half-dozen women who’d been trafficked across the state and pimped out to as many as 45 people per day.
Each of the six victims had been illegally smuggled into the country after being promised legal jobs and reunions with their families. Once in the U.S., however, the women — who were in their 20s and 30s — were forced to work as commercial sex slaves, according to officials.

“The

Human trafficking data has a home in St. Pete
June 6, 2023
She added that discerning those links would aid local and state law enforcement interventions. It would also provide a better understanding of trafficking rates, when people are most likely to become victims and how often they move to other locations or remain trapped in one spot.
Wagers noted that numerous state agencies work to combat human and sex trafficking and support victims. Those collect data alongside police departments and the state tip line.
She said the hotline is currently a primary information source. However, there are no follow-up investigations to ensure that someone is a trafficking victim or if multiple people reported the same person.
“So now, someone who wasn’t even a human trafficking victim gets counted twice,” Wagers explained. “Then there are other ones where no one ever calls, but they do come into the system and are appropriately labeled as a human trafficking survivor victim.”
She elaborated that the anonymous, national tip line information that places Florida as the third-worst state for trafficking is not “awful.” Wagers said it is just one data point and difficult to verify.
While there is no state ranking for the region, officials consider Tampa Bay a “hotbed.” Wagers said that is due to the area’s unique characteristics making it favorable for successful criminal or legitimate enterprises.
“If you had to quickly and efficiently move goods, you need access to certain things,” she added. “One is a port, and an international airport and freeways. Where you see these concentrations of human trafficking tips, they are in states – and then cities within the states – that have a couple of those features.

Naples mayor says complaint against her meant to sabotage reputation
May 26, 2021
An ethics complaint by City IT Director Brian Dye against the mayor in the City of Naples has brought forward serious accusations. It brought up allegations of corruption and child prostitution involving high-ranking leaders in Naples and Collier County.
We sat down with Mayor Teresa Heitmann who told us the complaint doesn’t look like something the IT director would write.
Heitmann believes the IT director was put up to it and she says a seven-page complaint is meant to sabotage her reputation.
“It’s shocking and impurely accusations that have potentially now harmed important relationships with the city,” Heitmann said.
The complaint claims Heitmann accused the former mayor and Sheriff Kevin Rambosk of running a child sex ring out of Naples Airport.

Slavery in our midst: Luncheon at yacht club spotlights human trafficking
January 24, 2018
The amazing thing is, slavery is happening today, in 2018, and all around us in our own community.
We tend to think of slavery or human trafficking as something from long ago or taking place in faraway lands. But as a group at the Naples Sailing & Yacht Club found out on Jan. 19, though, it is happening in this century, right here in Collier County.
Naples Community Church hosted the presentation to boost awareness of human trafficking, in recognition that January is National Slavery and Human Trafficking Prevention Month. The approximately 110 attending the luncheon heard from two people who are intimately involved in dealing with the problem, Collier County Sheriff Kevin Rambosk and Linda Oberhaus, CEO of the Shelter for Abused Women and Children.
Human trafficking can involve forced labor, often agricultural; domestic
servitude in the trafficker’s or another home; and sex trafficking,
Rambosk and Oberhaus told the gathering, taking turns and “tag-teaming”
the presentation. Because such a high percentage of the human
trafficking, especially that which ordinary citizens are likely to come
across in our area, is sex trafficking, that was the focus of most of
the discussion.

Sheriff candidate files ethics complaint against Rambosk
June 27, 2008
For the second time in three months, a candidate for Collier County sheriff filed a complaint with a state commission accusing fellow candidate Kevin Rambosk of violating state statutes.
Collier County businessman Vinny Angiolillo, the owner of Class Act Limousine in North Naples, filed a complaint this week, this time with the Florida Elections Commission.
In the complaint, Angiolillo, who once compared the Sheriff's Office to a criminal gang, alleges that both Rambosk and the Sheriff's Office "wantonly disrupted" his political campaign and caused "irreversible damage" to his campaign and reputation.
Sheriff Don Hunter called the complaint "enormously misleading." Rambosk, an executive officer with the Sheriff's Office, called it "politically motivated, irresponsible and malicious."
Angiolillo said he mailed the complaint on Thursday and confirmed its receipt on Friday. However, Kevin Smith, an investigator with the commission, said he could neither confirm nor deny receipt of the document due to commission policies...

• had sex with arrested offenders "in lieu of moving
forward to prosecution, eventually unarresting the individuals and
discarding the police report";
• stole property from the station;
• ordered lower-ranking officers to release arrested suspects and discard the reports, which would violate state law;
• improperly transported liquor in police vehicles for private parties;

Florida police officers entangled in widespread sex scandal
2013
LAKELAND,
Fla. – Authorities are investigating a widespread sex scandal involving
nearly a dozen police officers in one Florida city after a civilian
crime analyst detailed trysts with the men in police and fire stations,
patrol cars, motels and even in a parking lot after a memorial service
for a slain officer.
Sue Eberle, 37, has told officials that she
had consensual and sometimes coerced sex with the officers and a
firefighter, and that she once was propositioned by a city worker in
Lakeland.
Eberle's accounts of the liaisons were largely
corroborated by her sexual partners and others within the police
department, and published in a graphic, 59-page report written in an
incredulous tone by the county's top prosecutor. It said the
department's problems investigating crimes might be caused by some
high-ranking officers being more interested in having sex with Eberle
than doing their jobs.

Tallahassee corruption probe turns attention to judges: sources
2021
The
public corruption investigation that has gripped Tallahassee for the
last three years has expanded, according to law enforcement sources
close to the investigation.
Now, it has wrapped its tendrils around state courts in North Central and Northwest Florida.
It
isn’t clear which judges have caught investigators’ eyes, but there is
certainly some overlap with the investigation that snared Scott Maddox, a
former Tallahassee City Commissioner.
While judicial misconduct
is typically investigated by Florida’s Judicial Qualifications
Committee, the fact that federal investigators are now looking into
cases in Tallahassee means the fallout from the ongoing public
corruption investigation is far from over.
A hint on who may be
in the crosshairs: one of the Leon County judges who was supposed to
oversee Maddox’s disbarment was pulled from the case with no real

Indictments Shock Florida Town, Inured to Vice Reports

LAKE
CITY, Fla.—Corruption was way of life for so long in Lake City that the
community began to lose sight of the difference between fixing a
speeding ticket and letting criminals escape justice for a once.
That
is one view offered to explain why a Federal investigation of local
racketeering has led to the indictment of several prominent citizens,
including two of the four circuit judges in Florida's Third Judicial
District, on charges that a conspiracy existed to operate gambling,
prostitution and a drug ring, in addition to putting a price tag on
justice in the courtroom.
This small city 25 miles south of the
Georgia border was shocked by the indictments, but at least some of the
surprise seemed to be not so much that vice and corruption flourished in
Lake City but that the powerful had been brought to justice.
In fact, there was very little moral out. rage expressed.

FLORIDA JUDGES THAT CORRUPTLY UNDERMINE THE JUDICIAL SYSTEM AND THE RULE OF LAW
SADLY,
FLORIDA JUDGES have been exempt from the same level of scrutiny as our
politicians and the Media, but there are increasingly more pervasive
attacks on judicial integrity. Abuses of power, corruption, lack of
accountability, secrecy, and impunity from prosecution are eroding
public trust and confidence in the judicial system.
As judges and
public servants, the above individuals took an Oath of Office to uphold
and protect the U.S. and Florida Constitutions; to honor the Code of
Judicial Conduct, to uphold the Separation of Powers Doctrine, and to
respect the constitutional rights and civil liberties of all Floridians.
By ruling unconstitutional the Constitution and laws that are the
source of their authority, these corrupt judges automatically deprived
themselves of their own authority to rule.
For their corrupt,
racist, unconstitutional misconduct, Broward Circuit Court Judge Dale
Cohen, Monroe Circuit Court Judge Luis Garcia, Palm Beach Circuit Court
Judge Diana Lewis, and Miami-Dade Circuit Court Judge Sarah I. Zabel,
need to be removed from the bench by the Florida Judicial Qualifications

'A startling situation': Public Defender's Office struggling to keep attorneys
2023
LEE
COUNTY, Fla. — Southwest Florida is feeling the impact of a nationwide
issue: an attorney shortage. The Public Defender's Office for the 20th
Judicial District spoke with Fox 4 about the retention problems, and how
this could impact you.
Every day, someone accused of a crime
sits inside of a courtroom. If they cannot afford a lawyer, they can be
appointed a public defender. However, finding the lawyers to do that is a
problem in some areas.
The 20th Judicial District represents
Lee, Collier, Hendry, Charlotte and Glades counties with 60% of the
cases starting in Lee County. The office is run by Kathy Smith, the
public defender.
She manages 141 employees; 80 are attorneys. She
says it's not hard to convince people to work in Florida, but there are
still some roadblocks.
"My big issue is retention of those people," Smith said. "This is a tough job."
The
retention issue is something we're seeing across the country. Smith
says the reason behind the problem in her office comes back to money...

Federal corruption trial of North Florida lawyer underway in Jacksonville
Jun. 6, 2022
JACKSONVILLE,
Fla. (WCTV) - The federal corruption trial of North Florida lawyer
Marion Michael O’Steen is now underway in Jacksonville.
O’Steen was arrested and accused of a bribery and extortion scheme with former Third Circuit State Attorney Jeff Siegmeister.
Siegmeister
plead guilty in February and is listed as a witness in O’Steen’s trial
by both the prosecution and defense, according to federal court records.
O’Steen
is accused of making deals with Siegmeister to reduce the charges or
sentences of his clients. The February 2021 indictment says in one case,
O’Steen bought one of Siegmeister’s Braford bulls and in another case
asked a client to pay tens of thousands of dollars to make a gambling
charge “go away completely.”

Report: Moonlighting ex-Collier official lobbied for county vendor in 'apparent' conflict of interest
July 17, 2023
Sean
Callahan was quietly fired in January of 2022 after county staff
discovered he was secretly working as a lobbyist for a powerful
Washington D.C. lobbying firm — a moonlighting job that violated county
policies, ethical guidelines, and anti-fraud measures.
Now a new
report by the county’s Office of the Inspector General reveals that one
of Callahan's undisclosed lobbyist clients, Jacobs Solutions, is a
long-time vendor for Collier County.
The OIG report, which was
exclusively obtained by the Florida Center for Government Accountability
(FLCGA), found that Callahan was in “apparent” violation of the
county's conflict of interest policy when Jacobs Engineering and
CH2MHill, both subsidiaries of Jacob Solutions, became his clients.
Notably, these companies were appearing before the Board of Collier
County at the time with county purchase orders totaling $4.5 million.

Ethics, public corruption conference slated in Naples
2023
Forum of interest to attorneys, elected officials, journalists and the public
The motto of the City of Naples is “Ethics above all else.”
In
August 2020, voters in the City of Naples approved a referendum
establishing a Commission on Ethics and Governmental Integrity. This
independent commission is charged with, among other things, providing
ethics education and training for city employees, elected officials and
lobbyists and enforcing the city’s ethics code which includes “lobbyist
registration, reporting and regulation.” The code extends to elected
officials and employees and, in some instances, to third parties who
transact business with the city.
Ethics in government? Who could
possibly be against ethics in government? It may surprise you to learn
that the road leading to the creation of the Naples Commission on Ethics
and Governmental Integrity was a rocky one. Way back in 2016, a
then-City Council member voted on a proposed development in the city.
Subsequently,
it was discovered that this particular council person might have
engaged in a conflict of interest. Because there was no local agency to
enforce the then-existing ethics code in the city, a complaint was filed
in Tallahassee with the State Ethics Commission. (Ultimately, no
probable cause was found in the complaint). It was then that former City
Councilwoman Linda Penniman proposed the formation of a local
government ethics commission. The majority of the City Council at the
time rejected the idea.
A group of concerned citizens formed a
political action committee called Ethics Naples and began collecting
signatures to place a charter amendment on the ballot. The city fought
their efforts to get the referendum on the ballot. Who could be against
ethics in government? The city lost in court at the trial level,
appealed that decision and lost the appeal as well. By that time, it was
2020 and the composition of the Council had changed. Ray Christman, who
was a member of Ethics Naples, was elected to Council and the four
incumbents who opposed the ethics commission were swept out of office.
This led to the August referendum where 62% of the citizens of Naples voted to approve the creation of the ethics commission.
In November 2020, the first five volunteer members of the commission were appointed...

Naples officials: PAC declined way to resolve dispute over ethics panel
2018
A
referendum aiming to establish a Naples ethics commission will not
appear on the August ballot due to a legal battle between the city and
the PAC behind the referendum, but court documents show city officials
offered to expedite the process in May and the PAC declined.
The
city's dispute with the PAC, called Ethics Naples, could cost taxpayers
$40,000 if a special election is called for the referendum, a county
official said.
“We've been bending over backwards to try to
expedite the process,” Assistant City Manager Roger Reinke said. "Ethics
Naples has refused the city's offer to mutually expedite the hearing on
the matter."
In fact, Ethics Naples leaders "have done
everything they can to avoid having the courts examine whether the
petition is legal before having it placed on the ballot,” City Attorney
Jim Fox wrote in a June 15 email to the City Council.
Councilors
voted May 2 to let a judge decide whether the referendum, which would
establish an ethics commission if approved, would appear before voters.
The
next day, Fox recommended both parties agree to waive discovery and
expedite the summary-judgment briefing, which would have put the case
before a judge by the end of the month.
However, Ethics Naples
did not agree and instead filed an emergency petition in the Florida 2nd
District Court of Appeal, which transferred the case back to the 20th
Judicial Circuit.
Ethics Naples then filed another emergency
petition with Collier Circuit Judge James Shenko, even though the city's
original case already was pending in front of Collier Circuit Judge
Hugh Hayes. When Shenko realized that, he dismissed the emergency
petition.
"This clear attempt to forum shop ... was frivolous
and merely delayed resolving the dispute," the city wrote in response
to the PAC's emergency motion.
"If Ethics Naples truly
believed that this dispute was an emergency, then it should have ...
agreed to the expedited litigation.
"Instead, Ethics Naples
has spent almost a month shopping for a judge other than Judge Hayes and
doing everything it can to delay and avoid the constitutional
question."
Ray Christman, executive director of Ethics Naples,
said the PAC thought the emergency petitions were the most appropriate
action, given the city's approach to the case.
"The core issue as
far as we're concerned is the ministerial duty of the council to put
the issue on the ballot," Christman said.
"Had their (request for
declaratory judgment) been focused on that issue and only that issue,
we would have responded quickly and it's possible it would have been
done in time for the August election," he said.
Instead, the city's complaint focuses on more than a dozen alleged flaws with the referendum's language.
Ethics Naples has described that as a "piecemeal attack," and the PAC filed a request Tuesday to dismiss the city's complaint.
"The
city took an 'everything but the kitchen sink' approach in their
filing, which we thought was simply trying to distract the court from
what the issue really is," Christman said. "Those are matters to be
dealt with after the referendum is on the ballot."

But
that wouldn't be fair to voters, Reinke said. He compared the situation
to someone trying to push a referendum to segregate the city's drinking
fountains.
“Just because they got enough petition signatures,
does that mean we should put it on the ballot, even though it’s patently
illegal? Of course not,” he said. “This is the same idea, and if the
voters pass an illegal law, they’ll have the expectation that it’ll
somehow become legal.”
Although the council has until June 29 to
submit the referendum question to the county to place it on the Aug. 28
primary election ballot, a judge won't hear the case in time to meet
that deadline.
That means that if a judge decides the referendum
is legal, the city would have to host a special election, costing
$35,000 to $40,000, according to Trish Robertson, a spokeswoman for the
Collier County supervisor of elections.

More:PAC aims at August ballot for referendum on creating Naples ethics panel
According
to City Attorney Bob Pritt, one of the more questionable aspects of the
referendum is a requirement that any proposed amendment to the city's
ethics code by the ethics commission would become law unless five or
more City Council members vote against it.
The proposed
referendum states two of the five ethics commission members would be
appointed by the state attorney and the public defender for the 20th
Judicial Circuit, which includes Collier County. Pritt has said they
might have conflicts of interest if an ethics violation becomes a
criminal case.
Either party has the right to appeal the judge's
decision, Pritt said, so the case could end up back in the Florida 2nd
District Court of Appeal. It also could end up going before the Florida
Supreme Court or even the U.S. Supreme Court, although that's unlikely,
Pritt said.
Judge Hayes is scheduled to hear the case Aug. 21.

What is Form 6? Here's why so many elected city officials are abruptly resigning across Florida
2023
You
might be excused for wondering if a strange disease that only affects
local government officials is suddenly sweeping across the state.
Most of the North Palm Beach Village Council have resigned, including
the mayor, and Eagle Lake barely avoided losing a quorum.
The Naples vice mayor announced his resignation on Dec. 31.
Dunnellon’s mayor and a council member stepped down.
Four out of the five St. Pete Beach city council members resigned.
The mayors in Cedar Key and Williston announced their departures.
At least eight elected officials in Pinellas County have left office or plan to, according to the Tampa Bay Times.
Two Daytona Beach Shores city commissioners bailed, as have one in Fort
Myers Beach. one in Jacksonville Beach, one in Bradenton Beach and two
in Bartow.
Four of the five McIntosh Town Council members, two
city council members in Orange City, one in Sanibel and a town
commissioner in Longboat Key are gone.
The Town of Reddick lost the entire town council and the mayor.
Why are so many small-town elected officials across Florida abruptly resigning?
Among
the other new laws that took effect on Jan. 1, they had to reveal their
finances in detail for the first time. A change to the Ethics
Commission laws requires city and municipal elected officials to fill
out something called Form 6, the same disclosure form that state and
county elected officials have had to fill out for years. So would new
candidates for office, which could frighten some people away from
representing their communities.

We’re #1 {In Public Corruption}
June 21, 2012
https://naples.floridaweekly.com/articles/were-1-in-public-corruption/
NUMBER ONE.
In sports, it’s usually cause for celebration. In sales, in earnings, in awards or accolades, ditto.
But
in public corruption, the number-one ranking serves both as cause for
despair and as a wake-up call to people who elect or appoint public
servants. Their question should become, “Why, and how can we fix it?”
Now
Florida, once the pioneer and preeminent champion of open government,
has taken the number-one ranking for government corruption in the United
States, ahead of California, Texas and New York, each of which contains
a larger population.
Florida’s middle district, which includes
Collier, Lee and Charlotte counties and stretches from south of Naples
northward to the Georgia line, has played a significant role in spawning
government corruption. Here, Florida Weekly offers a glimpse of that
history in Southwest Florida, and the men and women who shaped it,
dating back about three decades.
Ironically, that’s roughly the
lifespan of the Sunshine State’s pioneering openrecords laws — laws
making public the actions of elected and appointed government officials.
“It’s
been (45 years) since Florida put in place government in the sunshine,
and we once held the leading position in the country and maybe the world
for giving the public the tools to hold government accountable,” says
Dan Krassner, executive director of the nonprofit watchdog group
Integrity Florida. “But that’s changed. Since that law was enacted, the
legislature has weakened it with more than 1,000 exemptions, which shows
Florida is moving in the wrong direction.”
Convictions of corrupt public officials show the same thing, perhaps.
Using
numbers from a U.S. Department of Justice report detailing a decade of
wrongdoing from 2001 to 2010, mostly in local government, Integrity
Florida reported that federal prosecutors convicted 781 men and women
for corruption and fraud, most of them working in local government.
In the Middle District, according to the report, there were 220 federal convictions alone.
That’s
not all. The Florida Commission on Ethics, a relatively toothless arm
of state government that cannot undertake investigations of officials
unless complaints are filed formally first, and can only levy fines of
up to $10,000, has done business in the region as well, says Cary
Stillman, a spokeswoman.
In the last five years, 30 complaints of
ethics violations by government officials were filed in Lee, 13 in
Collier and six in Charlotte County. Of those, there were four total
violations and three probable cause rulings, in which the Ethics
Commission took no further action.
Neither officials for the U.S.
Attorney’s office in the middle district or the state’s Ethics
Commission were able to provide names and descriptions of the federal
convictions or ethics violations by press time. But a glimpse at the
past and the present suggests that even if history doesn’t repeat
itself, its patterns and the tendencies of men and women who create it
anew, do.
Among other things, the numbers of convictions and
violations likely demonstrate that the more things change, the more they
remain the same.
Which is why history may prove the best teacher.
When corruption meant death, drugs
Within
the lifetimes of the oldest men and women who live in the region,
corruption could mean blood and an early 20th century version of
slavery, not just financial misbehavior. Across the South, including in
Southwest Florida, conscript labor camps created a widely accepted form
of official corruption unequaled since.
In an era before
open-government laws, black males and some poor whites were regularly
arrested on trumped up charges and used as conscript labor in turpentine
camps — lumber camps where pines were cut and processed for turpentine.
They led brutal lives, too frequently dying in the camps and being
buried in nameless graves from El Jobean to Babcock Ranch in Charlotte
County, and points south, historians report.
The perpetrators were never charged with any crimes, and authorities were well paid to provide the conscripts.
Almost everything official was done differently in those days.
Travelers
found dead along roads or trails, for example, were sometimes simply
disposed of in unmarked roadside holes, a solution that required no
inquests, no paperwork, and almost no trouble or public expense.
“It
was a fairly common custom,” recalled Vernon Peeples, the Charlotte
County historian and former state legislator, in a conversation with
Florida Weekly last year.
“If somebody was found dead, they’d
have a coroner’s jury, and men from the coroner’s jury would go out and
find the body and ask themselves if anybody recognized it. If no one
recognized the body, it was buried on the spot by the side of the road.”
For
decades, officials also used the poll tax to control votes, effectively
preventing many blacks and some poor whites who couldn’t afford to pay
it from entering the voting booth.
But Bartow native and United
States Sen. Spessard L. Holland brought that corrupt exercise to a halt
by sponsoring the 24th Amendment to the Constitution in 1964, which
prohibited the poll tax. By 1966 it had become law in all 50 states.
As
Florida grew and the population of the region began to swell beginning
in the 1960s, people began to pay more attention to official corruption.
Still,
it wasn’t always white-collar crime. During the famous drug busts in
Everglades City in 1983, for example, about 80 percent of the town’s
male population found itself behind bars for helping transport “square
grouper” — bales of marijuana. Nobody, including local officials, seemed
to care that since the 1970s many residents had been illegally taking
in hundreds of thousands or even millions of dollars in drug money until
the arrests, which were part of President Ronald Reagan’s war on drugs.
Then everything changed except white-collar corruption in local government.

Florida most corrupt? Not necessarily so, study says
6/17/2012
https://archive.naplesnews.com/news/state/florida-most-corrupt-not-necessarily-so-study-says-ep-388651567-342496342.html
Known
more for its sunny beaches and magical theme parks, Florida is getting
attention this month for a less flattering reason: corruption.
Florida
leads the nation in federal corruption convictions, according to a
report released in early June by the non-profit watchdog group Integrity
Florida.
From 2000 to 2010, Florida had 781 such convictions,
which include violations like misuse of public money, vote buying and
conflict of interest crimes. But that number, which comes from
Department of Justice data analyzed by Integrity Florida, doesn't tell
the full story, some say.
When considering population, Florida
ranked 19th in the country for corruption convictions, according to a
University of Illinois in Chicago study released this year that crunched
data from 1976 to 2010. And some say the high number of convictions
could be the result of the state's Sunshine Law — one of the most
expansive open records laws in the nation — or prosecutors who are
aggressive in ethics violation cases.
The University of Illinois
study found Florida had 0.94 public corruption convictions per 10,000
population between 1976 and 2010, good for 19th in the country. The
District of Columbia led the nation with 16.70 convictions per 10,000
population, followed by Louisiana with 2.00 and Mississippi with 1.89.
Jim
Nowlan, who co-authored the University of Illinois study, said there
are limitations to any data set measuring corruption. For instance, his
data accounts for factors like population and growth, but can't measure
qualitative factors like the amount of resources the U.S. Attorney's
Office had in pursuing the corruption cases.
"In one period of
time, the U.S. Attorney for several districts in Florida might be very
aggressive, or non-aggressive, for public corruption convictions,"
Nowlan said. "What I'm getting at is, you don't want to read too much
into this or parse it too finely. ... None of it is perfect."
Sen.
Garrett Richter, R-Naples, said Florida's large population — it's the
country's fourth most populous state — means it often is at the top of
national statistics. And the state's open records laws could help expose
corruption, thereby bumping up the ranking, he said.
"Florida's
Sunshine Laws are leading the nation for transparency and public
access," Richter said. "For example, I don't know of any other state
that has a program like Sunburst where any citizen can read every email
from their governor and his top staff."
Although public
corruption cases typically are expensive and time-intensive, they remain
"paramount as one of the priorities in a democratic society," said
Robert O'Neill, U.S. Attorney for the Middle District of Florida.
"Prosecutors
here tend to be pretty vigilant," he said. "Law enforcement tends to
work these types of cases, and I think the courts are tough on them when
they're brought before them."
Dan Krassner, an author of
Integrity Florida's analysis, said his organization accepts those
factors as possible explanations for Florida's high ranking but he
remains concerned about the gross number of convictions.
Imagine
if Florida led the country in murder convictions, he said. Although that
could indicate good sleuthing by law enforcement, "that would still be a
problem for our state's reputation, and an issue policy makers would
want to address."
The Middle District of Florida, which includes
Collier and Lee counties, had 248 federal corruption convictions in the
11-year period analyzed by Integrity Florida. But getting numbers
specific to Southwest Florida is difficult, in part because the Middle
District includes large cities like Jacksonville, Orlando and Tampa.
The
most notable corruption scandal in recent Collier County history was
the Stadium Naples case, in which 10 local public officials and
businessmen were found guilty of swapping bribes to help get a proposed
$100 million golf stadium built in the late 1990s and early 2000s.
Since
then, Collier amended its ethics code, which now requires officials to
report all gifts, even though Florida law doesn't require disclosures
for gifts less than $100. Collier County Judge Mike Carr, who helped
draft the changes as a state ethics committeeman, said he believes
corruption is cyclical and is far less rampant today than it has been
historically.
"Ten years ago, Collier County was at the sipping
cup of corruption; now, I think it's as honest as any place on earth,"
he said.
Around the same as the Stadium Naples scandal came to
light, a two-year internal investigation by the Collier County Sheriff's
Office found two deputies in the Immokalee district were abusing their
badge. Jim Sanders pleaded guilty in 2001 to taking money from gambling
tables at illegal Immokalee gaming houses in exchange for not making
arrests or shutting the gambling businesses down.
A federal judge
found his colleague, Glendell Edison, guilty of distributing $500,000
worth of cocaine and taking payouts from drug dealers in exchange for
protecting them from arrest. Edison later pleaded guilty to state
charges saying he once saw three children tied up behind a meat slicer
at an Immokalee store, but took more than $4,000 from the boys' parents
in exchange for not reporting the abuse.
The case built by
internal affairs investigators helped secure the indictments against the
men. Sheriff Kevin Rambosk said the role of the internal affairs bureau
remains important today.
"Any complaint, no matter the level or
severity, is intaken by the agency," he said. "We want people to know
that we are open to both compliments and complaints, and that we'll
follow it through to a resolution."
Carr, the Collier County
judge, said new countywide regulations have birthed a "different
climate" where officials are more aware of habits that could become
corrupt.
"There's a saying that 'All that is necessary for evil
to triumph is for good men to do nothing.' That saying is as true now as
it was then," Carr said. "Corruption doesn't say, 'I'm corruption, and
welcome me.' It sneaks up on you with good ol' boys,
we're-just-trying-to-be-nice, we're friends.
"If people know that you've got someone looking over your shoulder, it makes it easier to stay honest."

Lighthouse Project - History: Stadium Naples was biggest public corruption scandal in local history
4/2/2012
https://archive.naplesnews.com/special/lighthouse/lighthouse-project---history-stadium-naples-was-biggest-public-corruption-scandal-in-local-history-e-342577612.html
ESPN
founder Bill Rasmussen unveiled plans for a first-of-its-kind golf
stadium in 1996, an ambitious, $100 million project to be located
northeast of the city of Naples. The facility, to include luxury
skyboxes and 12,000 seats surrounding the course's 18th hole, would be
called Stadium Naples. But the stadium was never built. Plans fell apart
under controversy and public outrage when a Naples Daily News
investigation revealed in 1997 that an elected official, then Collier
County Commissioner John Norris, had negotiated for a stake in Stadium
Naples estimated at $7.5 million before casting votes to benefit his
developer partners and the stadium.
The controversy would only
grow from there. Following the urging of residents and the local
Republican Party, then Gov. Jeb Bush ordered a detailed investigation
into the matter, as well as the assignment of a special prosecutor.
What
resulted was the largest corruption case in Collier's history, netting
charges against 10 people: four public officials, five business leaders
and an attorney. For more than six years, investigations into the
project, which was attempted a second time with now defunct Naples-based
brokerage company A.S. Goldmen & Co., continued.
The case
was sprawling and complicated. Eventually, the public would learn that
A.S. Goldmen & Co. had manipulated a number of small company stocks,
including Stadium Naples partner Millennium Sports Management, in what
state and federal securities regulators dubbed one of the nation's most
notorious boiler rooms. It would learn that David Mobley, the financier
whose Maricopa Investments backed Stadium Naples and The Strand, was
cheating investors of millions, pumping their money into his posh
lifestyle and failed businesses and charities.
'People were
closing their eyes; the whole society was rupturing with corruption,'
Mike Carr, a Collier County judge who was then a Republican state
committeeman and leading voice in calls for an outside investigation,
said of the time.
'Roads weren't being built. Developments that
shouldn't have been built were being built. Zoning decisions were not
based on merit but who was being paid off; taxes weren't being collected
on fancy golf clubs. The saying around here was, 'To get along, you go
along.' It was a cesspool.'
'We've been amazed at the
institutionalized corruption we've been seeing,' special prosecutor
Michael Von Zamft said in October 2001, when prosecutors unveiled
sweeping new corruption charges and the last five arrests.
Prosecutors
charged the 10 Stadium Naples co-defendants with conspiring to deprive
the citizens of Collier County of the honest services of public
officials by swapping financial incentives for votes and influence
favorable to their projects.
Although initially only Norris was
in the spotlight for wrongful dealings with developers, it was later
revealed that other county officials had also accepted gifts and favors
from them.
'Crooks are like cockroaches and the sunlight makes
them run,' Carr said. Once the first hints of corruption began coming
out, he said, the rest followed.
Then Commissioner Tim
Constantine, the public learned in 2000, received a discount on his
wedding reception at a country club and a $100,000 business loan from
the Stadium Naples developer. The loan wasn't repaid.
It learned
Neil Dorrill handed out pay raises to key county employees days before
leaving his job as county manager in 1997 to become president of the
first Stadium Naples development partnership.
Tim Hancock,
another county commissioner at the time, admitted to taking more than 40
free golf games from lobbyists while in office.
Several years
would pass before the case ended in January 2004 with the last remaining
defendant, Norris, striking a deal with prosecutors.
The defendants were dealt varying sentences, ranging from community service to house arrest and thousands of dollars in fines.
The
case led to changes at the state and local level. Ethics ordinances
were passed by both city and county government. And the Florida
Legislature amended state law, stiffening penalties for public
corruption.
Commissioner Fred Coyle, who was a city council
member when the city's ordinance was adopted, said the new rules help
sensitize elected officials to how the public perceives their
interaction with developers. The ordinances closed the loopholes and
prohibit officials from engaging in activities that could even be viewed
as unethical.
'We probably overreact in some cases,' Coyle said. 'We are probably overly cautious and that's not bad.'
Carr
said although 'there's more money here (and) you're going to get more
crooks gravitating toward money,' he believes the area's elected
officials to be honest and he is proud of that. The county, Carr said,
has to continue to maintain integrity and take the stance that
corruption is unacceptable.
'If we keep in mind what's happened before, we can make new mistakes,' he said. 'We don't have to make the old ones.'

Governor's call to investigate public corruption includes Lee, Collier counties
2009
The
government corruption probe Gov. Charlie Crist asked the Florida

Southwest Florida is familiar with public
corruption. Investigations, indictments and prison terms have taken down
county commissioners in both counties, though it's believed recent
high-profile arrests in Broward and Palm Beach counties more likely
spurred the governor's request.
Stadium Naples was the largest
public corruption case in Collier history. It was rooted in ESPN founder
Bill Rasmussen's plans for a $100 million golf stadium in North Naples,
a scheme that involved three county commissioners, a former county
manager, three developers, a convicted hedge fund manager and a real
estate attorney.

Massive human trafficking operation busted in Florida with more than 120 arrests
2024
Undercover
stings in Florida resulted in the arrest of more than 120 people -
including a teacher, nurse, basketball coach, and even a person employed
by a spiritual organization - as part of a sweeping operation targeting
human trafficking.
Fox13 reported the investigations were part
of Operation Renewed Hope, a 90-day human trafficking operation under
which 123 individuals were arrested, and 28 victims were saved.
In
a press conference aired on Fox13, Hillsborough County Sheriff Chad
Chronister said investigators targeted this crime through a
"multipronged approach" by conducting several undercover prostitution
stings and hotel/motel operations.
The sheriff added that
undercover investigators posed as minors available for sex via online

Florida's Worst Corruption Scandals, Ranked
10/28/2015
Nobody
does corruption quite like Florida. Sure, places like Illinois and
Detroit have had high-profile cases, but no state has public corruption
to quite the extent that we do (seriously, Integrity Florida found that
between 1976-2012 over 1,760 public officials in this state had been
convicted of corruption), so narrowing it down to a top 12 is almost
impossible. Almost. From a US attorney biting a stripper to dead people
casting votes, here are the dozen weirdest, most egregious, and just
flat-out only-in-Florida political scandals in our history.
5. Operation Court Broom
Ah,
the 1980s in Miami. A time when a judge could sell his decisions,
freebase cocaine, and dime out drug informants to cartels for a measly
50 grand. Or at least they could before Operation Court Broom. That’s
the name of an FBI sting of Dade County judges, where fake cases were
created and Manuel Noriega’s lawyer wore a wire to catch five judges,
who took up to $50,000 to fix cases. Two of the most upstanding among
them: Harvey Shenberg, who gave up the name of a confidential drug
informant to a cartel for $50,000. And Phillip Davis, who when federal
agents raided his home looking for marked cash used in the bribery
sting, found Amanda Bynes-levels of cocaine along with all the tools
used for freebasing.
2. Miami River Cops
The 1980s were
not exactly a glorious time for the Miami Police Department, and
bottomed out with the Miami River Cops. In summer 1985, a boat full of
$12 million worth of cocaine docked on the Miami River, and somewhere
along the line the offload went bad. A nearby night watchman called the
police claiming gunfire during a “police raid," but somehow the raid
mysteriously had no police report. Nor were the 400 kilos of cocaine on
the boat ever heard from again. Though they may have been floating in
the Miami River next to the three dead bodies that resulted from the
“raid.” The missing drugs prompted an investigation that unearthed a
network of crooked Little Havana cops who shook down drug dealers, stole
their money and drugs, and profited from it all. In the end, 24 cops
were convicted and 17 went to prison as a result of the investigation.
1. Miami mayoral recall
Why
the world was even slightly surprised South Florida botched the 2000
presidential election is a mystery to anyone who was here in 1997. That
was the year that, despite capturing nearly half the vote in the general
election, Joe Carollo lost the mayoral runoff to Xavier Suarez. The big
difference during the runoff? Some very important voting blocs turned
out to pull the lever for Suarez, including the dead, convicted felons,
non-residents of Miami, and homeless people Suarez staffers paid $10
apiece. Also credited for his win: a flood of absentee ballots coming in
from City Commission District 3 represented by... Humberto Hernandez,
who at the time was on suspension pending federal indictment. While the
FDLE investigated and Suarez encouraged Miamians to keep their mouths
shut, a federal trial began in February, and a month later the election
was declared invalid. Joe Carollo ultimately took over as mayor, several
Suarez staffers were indicted, and Humberto Hernandez still went to
prison.

Florida's election police investigating alleged election crime in Collier County
Feb 22, 2024
COLLIER COUNTY, Fla. —
NBC2 has confirmed that Florida's election police are investigating whether an election crime was committed in Collier County.
The
investigation comes after Collier County voters last week reported
receiving misleading text messages claiming they requested a mail ballot
when in fact they did not.
The matter has now caught the
attention of Tallahassee. All of this is happening right in the middle
of the presidential preference primary as voters are going out and
already casting a vote. Collier County Supervisor of Elections Melissa
Blazier reports she has turned all of the information she gathered over
to the governor's election police.
Shortly after the misleading texts went out, Blazier posted on social media that the political PAC Win America was behind it.
The
text made it seem like it came from Naples candidate for Mayor Gary
Price, who said DC politics was showing its ugly face in Naples.
“Quite frankly this seems like election fraud,” Blazier told NBC2.
Today she confirmed she's asked the Office of Election Crimes and Security to investigate.
“I
ended up packaging up the information and I spoke with the Office of
Election Crimes and Security in Tallahassee who advised 'Yes, they would
like to investigate,'" Blazier said.
She said the Win America PAC continues sending out misleading text messages about the Price campaign.
She’s
concerned that if a local municipal race is creating this much
controversy, a national presidential race could become even more
contentious.
“I think that's why in the end I decided we should
get involved because yes if you look at what is happening now in small
municipal election I can only imagine what's going to happen in
November,” Blazier said.
Price said the state’s election police have not contacted him but that he would cooperate if they reach out to him.
“I
think voters have lost a lot of confidence and that is one of the
things I think we need to preserve is that people feel comfortable with
their election regardless of the outcome,” Price said.

Jewish Bolshevism
https://en.wikipedia.org/wiki/Jewish_Bolshevism
Jewish
Bolshevism, also Judeo–Bolshevism, is an antisemitic conspiracy theory
that claims that the Russian Revolution of 1917 was a Jewish plot and
that Jews controlled the Soviet Union and international communist
movements, often in furtherance of a plan to destroy Western
civilization. It was one of the main Nazi beliefs that served as an
ideological justification for the German invasion of the Soviet Union
and the Holocaust.
After the Russian Revolution, the
antisemitic canard was the title of the pamphlet The Jewish Bolshevism,
which featured in the racist propaganda of the anti-communist White
movement forces during the Russian Civil War (1918–1922). During the
1930s, the Nazi Party in Germany and the German American Bund in the
United States propagated the antisemitic theory to their followers,
sympathisers, and fellow travellers.

History of the Jews in Cuba
https://en.wikipedia.org/wiki/History_of_the_Jews_in_Cuba
Jewish
Cubans, Cuban Jews, or Cubans of Jewish heritage, have lived in the
nation of Cuba for centuries. Some Cubans trace Jewish ancestry to
Marranos (forced converts to Christianity) who came as colonists, though
few of these practice Judaism today. The majority of Cuban Jews are
descended from European Jews who immigrated in the early 20th century.
More than 24,000 Jews lived in Cuba in 1924, and still more immigrated
to the country in the 1930s. Following the 1959 communist revolution,
94% of the country's Jews emigrated, most of them to the United
States. In 2007 an estimated 1,500 known Jewish Cubans remained in
the country, overwhelmingly located in Havana. Several hundred have
since immigrated to Israel. Considered one of the most important Latin
American Jewish sites, Beth Shalom Temple is the epicenter for current
Jewish life in Cuba and still conducts weekly Shabbat services.
In
addition to the descendants of Cuban Jews living in the United States,
there is also a significant population which claims descent from
non-Cuban Jews and from Cuban gentiles.

According to a 2009 report by the Pew Hispanic Center, in 2007 Latinos "accounted for 40% of all sentenced federal offenders ‒ more than triple their share (13%) of the total U.S. adult population". This was an increase from 24% in 1991. Between 1991 and 2007, enforcement of federal immigration laws became a growing priority in response to undocumented immigration. By 2007, among Hispanic offenders sentenced in federal courts, 48% were immigration offenses, 37% drug offenses, and 15% for other offenses. One reason for the large increase in immigration offenses is that they exclusively fall under federal jurisdiction.

The Dirtiest Cops In America; Brevard County Sheriffs Take 1st Place
Brevard Counties Sheriffs Department... Police Corruption Is Not Just Accepted, It's Mandatory.
"Brevard County come on vacation, leave on probation..."
It's
sad to say that these are police stationed in our great nation, the
Brevard County Sheriffs Office is without a doubt a disgrace, not only
to every other American police department but also to the United States
of America entirely. Which is why I've decided to bring their
unjustified, unconstitutional behavior to light. So that the rest of the
country can be made aware of the mockery that they are making of
upholding the law. Here the Sheriff is a celebrity, criminal justice is a
game show, and even the pettiest of criminals are treated like they are
enemy forces of a rival country instead of the American citizens they
truly are. This county fuels its economy by ripping apart one family
after another and destroying the lives of countless individuals. Too
many lives to count in fact, all ruined by the most pathetic
interpretation of criminal justice modern America has ever had to
witness. It's time for this Sheriffs department to finally be held
accountable for their actions, so that, maybe one day, they'll no longer
be one of the most corrupt police departments in the country...

Ron DeSantis just accepted $100K from the GEO Group, a controversial Florida-based private prison giant
Aug 17, 2018
A
political action committee supporting Florida Republican gubernatorial
candidate Ron DeSantis just got a $100,000 from the GEO Group, a
Florida-based private prison giant known for numerous human rights
investigations.
According to public records, on Aug. 15 the
Friends of Ron DeSantis PAC accepted $50,000 from GEO Group, Inc. and
another $50,000 from the company's CEO, George C. Zoley.
The GEO
Group, which is headquartered in Boca Raton and is the second largest
private prison group in the country, was an early supporter of the
DeSantis campaign. Records show they also gave the congressman another
$50,000 back in March of 2017.
DeSantis isn't alone. The GEO
Group has sprinkled cash all over Florida politicians, including Sens.
Marco Rubio and Bill Nelson, according to the National Institute on
Money in State Politics. In fact, it's hard to find someone who hasn't
taken money from the group.
But it makes sense the GEO Group is
heavily backing DeSantis, considering the congressman parrots everything
the president says, and they directly profit from Trump's abysmal
immigration policies.
According to the investigative website
Sludge, the GEO Group currently holds almost a half billion dollars in
ICE contracts. For some perspective, last year the Trump Administration
spent a record $1.7 billion on private contracts, which means the GEO
Group gets more direct cash from ICE than any other company. Plus, it
doesn't hurt that former aides to Attorney General Jeff Sessions are now
lobbyists for the GEO Group.
The company is a private prison
behemoth and has immigration detention centers all over the country,
including Colorado, Arizona, New Mexico, Washington, California, and of
course, Florida.

{Many assume that Desantis
wants to stop illegal aliens and sanctuary cities. These unlawful
immigrants go against the wishes of the scientific community with illegal immigration. Desantis
wants to kick illegal immigrants out of Florida, but that these
illegal immigrants might end up in other states and sent to private
prisons in America. The problem is that these unlawful immigrants are
released and set free in America still. It is good that Desantis has
sent the Florida National Guard to the Texas border to stop illegal
immigrants. The problem is that unlawful immigrants are being put in prison work camps for a few years to make profit for the private prison industries. These unlawful immigrants are then released back into America after their prison term in these prison work camps for unlawful immigrants. The Biden Administration wants to make these unlawful immigrants citizens of America.
Desantis
was critical about the COVID vaccine which is also good. We support Ron
Desantis and sending the National Guard to the border to protect
America. We however were not in favor of how Desantis would just put unlawful immigrants in prison work camps, then these unlawful immigrants are released back into America once their prison sentence is up. Desantis was associated
with a group that took money from the GEO Group private prison company.
We think that we should not assimilate these illegal Third World
immigrants to become American citizens. The country is already full and that we should not waste more natural resources on unlawful immigrants who refuse to cooperate with the scientific community and the population census. We can see the direct harm that these illegal immigrants have caused the environment. A lot of the groundwater in America is drying up, these unlawful immigrants just add more to the problem}.

DeSantis recruiters eyed Catholic church for migrant flights that bishop calls ‘reprehensible’
June 8, 2023
SAN
FRANCISCO (AP) — Florida Gov. Ron DeSantis’ recruiters set their sights
on Sacred Heart Catholic Church in the Texas border city of El Paso in
search of asylum-seekers they could take from its bustling migrant
shelter to California’s capital on taxpayer-funded private jets.
Intentionally
or not, envoys for Florida’s Catholic governor and Republican
presidential candidate infused an element of his own religion into his
latest move on immigration, which has drawn sharp criticism from El
Paso’s Catholic bishop.
“Without going into the details of the
politics of it, it does seem clear that they were being used not out of
concern for the migrants but in an effort to make a political point,”
Bishop Mark Seitz told The Associated Press on Wednesday.
Seitz
said many migrants arriving in the U.S. don’t know the geography,
including how far cities and states are from one another, and are just
anxious to move on.
DeSantis has acknowledged that Florida paid
to transport 36 mostly Venezuelan migrants from Republican-led Texas to
Sacramento on charter flights last Friday and on Monday. The first group
was dropped off in front of the Roman Catholic Diocese in Sacramento,
also the headquarters of Catholic Charities, apparently without warning.
Local advocates and officials met the second group at the airport after
learning of their arrival.
The governor says they made the trip
voluntarily — a claim that some migrant advocates challenge. He also
says they signed waivers to that effect and that California effectively
invited them with its welcoming policies.
“I think the border
should be closed. I don’t think we should have any of this. But if
there’s a policy to have an open border, then I think the sanctuary
jurisdictions should be the ones that have to bear that,” DeSantis said
Wednesday at an event for law enforcement officials in Sierra Vista,
Arizona.
Asked about the bishop’s criticism, DeSantis spokesman
Jeremy Redfern said the governor’s previous comments “stand on their
own.”
In May, DeSantis signed a law allocating up to $12 million
for migrant flights, like two that Florida funded last year from San
Antonio to the pricey Massachusetts island of Martha’s Vineyard.
References
to the Martha’s Vineyard flights have become a staple in DeSantis’
presidential stump speech and often draw hearty applause from Republican
primary voters. The Sacramento flights are part of a broader effort by
certain Republican-led states to send migrants to Democratic-leaning
parts of the country, including New York, Washington, D.C., and Chicago.

MIAMI – On April 19, a local pharmacist was charged by criminal complaint with attempted sex trafficking of a minor and attempted travel to engage in illicit sexual conduct.
According to the criminal complaint and the underlying affidavit, law enforcement officers stopped Stefan Andres Correa, 42, of Miami, Florida, attempting to board a flight from Miami to Bogota, Colombia. It is alleged that, law enforcement officers discovered nine cellular phones in Correa’s possession containing videos of Correa engaging in intercourse with purported minor children, as well as a chat exchange with a suspected sex trafficker, where Correa allegedly paid for commercial sex with children aged between 10 to 12 years old in Colombia. According to the allegations, during the chat exchange, Correa agreed with the suspected sex trafficker to meet with the minor victims once he arrived in Colombia.

Gainesville’s city audit controversy, explained

https://www.alligator.org/article/2022/11/gainesvilles-city-audit-controversy-explained
After
delayed financial reports to the state, the Gainesville city auditor’s
resignation and planned international commission trips, some local
residents are worried about their tax dollars.
Four successive
issues led to local concern: a formal letter from the state about late
city financial reports, three city commissioners traveling to Israel off
public funds, the city auditor’s resignation and budget changes made
Nov. 17.
Gainesville’s upcoming fiscal budget is around $445
million, with about $14 million of general fund debt made up of bonds
and other obligations.
Juli Aitch, Gainesville resident, said
recent decisions were irresponsible given the situation.“They are
robbing the citizens of Gainesville,” Aitch said.
However, Gainesville city officials say the series of financial controversies were both expected and planned for.
Commissioners’ trip to Israel
City
Commissioners David Arreola and Adrian Hayes-Santos, as well as Mayor
Lauren Poe will travel to Israel for MuniWorld, an international city
government conference. The three will leave Dec. 2, just over a month
before they all exit office after reaching their term limit.
MuniWorld
is a three-day convention for cities across the globe. Participants
will see Jerusalem’s tech startup projects, connect with other
municipalities and watch lectures on local government practices.
The attendance fee is $200 per person and accommodations are $600, according to its website.
City
Commissioner Cynthia Chestnut first expressed concern over the trip,
calling it a waste of money given the city’s financial circumstances.
“This
international trip taken by commissioners with expenses paid by public
funds is disingenuous to all our constituents,” Chestnut wrote in an
email to them.
For each fiscal year, commissioners receive a
$5,000 stipend for travel. The 2023 fiscal year began Oct. 1. Chestnut
also said the trip would take travel funding away from oncoming
commissioners, though Arreola and Hayes-Santos said that was
inaccurate.“When the new commission is sworn in, they will have their
own budgets,” Arreola said.

February with the release of a scathing audit that read like a textbook
of municipal malfeasance – finding 31 violations of local, state and
federal codes, along with allegations of nepotism, double-dipping and
personal use of city property.
Surviving was a sweet win for this
city of just 477 residents – 476 if you don’t count the former mayor,
who’s sitting up the road in jail on a drug charge.
Already a
notorious speed trap, the place gained even more infamy as a symbol of
small-town corruption when the legislators threatened last month to yank
its city charter. Late-night comedians mocked Hampton as “too Florida,
even for Florida.”

Trafficante crime family
The
Trafficante crime family, also known as the Tampa Mafia, is an
Italian-American Mafia crime family based in Tampa, Florida. The most
notable boss was Santo Trafficante, Jr. who ruled Tampa and the crime
family with an iron fist. Author Scott Deitche reported that Santo
Jr. was involved with the CIA to plot assassination attempts on Fidel
Castro. After the death of Santo Jr. in 1987, the Tampa Mafia family
has been controlled by Vincent LoScalzo.

The
Bufalino crime family, also known as the Pittston crime family, the
Scranton Wilkes-Barre crime family, the Northeastern Pennsylvania crime
family, the Northeastern Pennsylvania Mafia, or the Scranton Mafia, was
an Italian-American Mafia crime family active in Northeastern
Pennsylvania, primarily in the cities of Scranton, Wilkes-Barre, and
Pittston.
D'Elia the last boss
William "Big Billy" D'Elia
became the new boss of the Bufalino crime family after the death of boss
Russell Bufalino in 1994. He started his criminal career in the
Bufalino family in the late 1960s as Bufalino's driver, after his late
sister married the only son of capo James David Osticco. According to
the Pennsylvania Crime Commission, D'Elia was placed in the crew of
Caporegime Phillip Medico. D'Elia advanced through the ranks of the
organization rather quickly, due to the natural attrition of members and
indictments in the 1980s and 1990s. He took over the crime family's
solid waste rackets and oversaw the traditional Mafia rackets run by the
members and associates of the family. D'Elia also attempted to
replenish the aging ranks of the family, with limited success. As boss,
D'Elia worked with the other crime families in New York City,
Pittsburgh, Philadelphia, Southern Florida, and Los Angeles. In the
1990s, D'Elia was linked to a money laundering scheme involving numerous
Northeastern Pennsylvania bookmakers, escort services, corrupt
politicians, and associates of Russian organized crime. D'Elia was
closely aligned with the Philadelphia crime family.[19] When
Philadelphia crime family boss John Stanfa was imprisoned, D'Elia was
one of Stanfa's choices as interim caretaker of the family.

MAFIA LINK SEEN IN TRASH CARTING IN WEST FLORIDA
July 3, 1983
Florida
has begun to crack down hard on racketeers from New York who, according
to Federal and state prosecutors, are invading the garbage collection
and disposal industry here on the state's west coast.
On Tuesday,
the Florida Attorney General, Jim Smith, and the Pinellas County State
Attorney, James T. Russell, jointly filed a civil antitrust suit against
20 individuals and 12 west Florida refuse hauling companies. At a news
conference, the officials described the defendants as practitioners of
''mob-style control'' of the trash hauling industry in this booming
retirement area. Threats and Beatings Cited
In January, the
United States Justice Department's Organized Crime Strike Force in the
Tampa area is to begin trying a major criminal racketeering case against
11 people, including five of those named in the state's civil antitrust
suit. The five, identified by the Federal Bureau of Investigation as
Mafia members or associates from New York, are accused of conspiring to
seize control of garbage disposal here by ''getting tough.''
The
indictment cites threats, extortion, beatings, pistol whippings and the
burning of garbage trucks belonging to local trash haulers who resisted
the mob takeover. One defendant is quoted in the indictment as saying
these actions are ''operating as in New York.''

Tampa and the mob: From bolita to Trafficante
Nov. 16, 2022
TAMPA,
Fla. - From the gangland days of the early 20th century to the 1960s
and 70s gangsters, the mafia and Tampa have always been intertwined.
During
its mid-century peak, organized crime controlled or had a hand in
everything from gambling and prostitution to political corruption,
election rigging, unions and more.
And Tampa was right in the middle of it.
On
this episode of To The Point Already, anchors Rick Elmhorst and Roy De
Jesus talk with organized crime writer Scott M. Deitche about Tampa's
vivid mob backstory.
"The history of the mafia in Tampa is part
of the history of Tampa," said Deitche, a Bay area-based writer who has
written extensively about mafia history in Tampa. "(Mafia bosses)
controlled politicians, elections and had hands in legitimate
businesses."
The fabric of the Tampa's history is richly woven
with stories of ruthless gangsters who first grabbed control of illegal
bolita gambling and liquor distribution during Prohibition, executed
rivals, controlled the narcotics trade and eventually broadened their
influence across Florida and into pre-Castro Cuba.
Infamous in
the city's lore is the "Era of Blood," when 25 gangsters were gunned
down on the streets as Italian, Cuban and Anglo underworld factions
battled for power from the 1920s to the '50s.
And a
Godfather-like legend surrounds Tampa-born crime boss Santo Trafficante
Jr., who took over the Sicilian Mafia in Florida from his father in 1954
and built a criminal empire that was the envy of mob families across
the country.
Trafficante famously never spent a night in an
American jail. Trafficante died in 1987 following a heart operation and
the Tampa mob's heydey died with him.
Deitche's book "Cigar City
Mafia" is a who's who of Tampa gangland activity. He followed that up
with a book on Trafficante and also operates Mafia Tours in Ybor City.
He says it's the mafia characters that fascinate people to this day.
"It's
part of the history of Tampa," he said. "I try to tell it as
even-handed as I can. When I do the tour, when I talk to people and show
them where this guy got whacked, they're eyes light up. People respond
to that.
"I can talk about the minutiae of the political corruption but (people) are more interested in the big crime."

Mafia has long history in South Florida but new ways and new rivals
March 21, 2010
Ever since the ruthless Chicago mobster Al Capone bought a mansion on Miami's Palm Island in 1928, South Florida has been a destination for organized crime figures who want to relax and do a little business.
The rackets have evolved over the years — loan-sharking, extortion and gambling have largely given way to stock scams, money laundering and white-collar fraud — and the Italians and Jews of yore have been joined by rival contingents from Russia, Israel and South America.
But the culture of greed and violence has remained a constant.
Mobsters generally prefer to keep a low profile here, but La Costa Nostra — "this thing of ours" — is once more in the headlines, this time connected with Ponzi schemer Scott Rothstein.
Upon his return from Morocco last November, Rothstein reportedly went to work for the FBI, even as agents were dismantling his $1.2 billion investment fraud.
Roberto Settineri, the alleged Sicilian mobster whom Rothstein is credited with bringing down this month, appears to have the same short fuse and propensity for violence, according to a Miami Beach police report, that has marked mob behavior for a century...

New insight into the mob connections in Southwest Florida
November 1, 2018
Here
in North Naples, the intersection of Orange Blossom Dr. and Bridgewater
Bay Blvd. seems completely calm and quiet. But in April of 2017, the
intersection is where law enforcement nabbed one of the men now accused
of killing notorious gangster Whitey Bulger.
“He was protected by the FBI,” John Pollok said.
Pollok
was the attorney for many of the mobs’ biggest names. These include
Angelo the “Duck,” Johnny Dio Guardi and John Gotti. Pollok now lives in
North Naples. He said, Whitey Bulger’s years as an informant made him
vulnerable.
“His position apparently to inform on the mob,” Pollok said, “they didn’t appreciate it.”
“They,”
as in organized crime. Freddy Geas, the man picked up by the Collier
County Sheriff’s Office years ago and reputed Mafia hit man.
Pollok
said the vicious attack on Bulger only a day after his transfer to the
West Virginia prison is all part of the mob mentality.
“For may
years the FBI protected him despite the fact — he was one bad dude,”
Pollok said. “They don’t forget, but neither does the mob.”
But the mob did seem to remember Southwest Florida as a hiding ground, Pollok said.
“Oh yes!” he said. “They would. They like the weather like anyone else.”
But Pollok believes Bulger’s death signals a change.
“The Godfather,” Pollok said. “Those days we think of are over”

Poisoning for Profit - The Mafia and Toxic Waste in America
1985
Annotation
Information from undercover investigations, hearings, taped conversations, confessions, and suppressed official reports documents organized crime's involvement in illegal toxic waste dumping and the ineffectiveness of government agencies responsible for regulating toxic waste disposal.
Abstract
A historic review chronicles organized crime's domination of the solid waste disposal industry in the Northeast and the illegal tactics used to eliminate competition and fix prices. The expansion of organized crime into toxic waste disposal is then detailed, with particular attention to the practice of dumping such wastes in areas not legally designated as toxic waste dump sites. Case studies of the consequences of such dumping are presented. Also described are the efforts of a few law enforcement officials to counter illegal toxic waste disposal and expose the payoffs, bribes, political favors, and collusion between organized crime, industry, and the government that hindered a concerted effort to stop illegal toxic waste dumping. Although much of the book focuses on illegal toxic waste dumping in the New York-New Jersey region, evidence of the same pattern in other States is also presented. The halting and sometimes obstructionist efforts of the Environmental Protection Agency under the Carter and Reagan administrations regarding the regulation of toxic waste dumping are discussed. 56 references and a subject index.

Toxic waste dumping by the 'Ndrangheta
The 'Ndrangheta, a criminal organization from Calabria, Italy, has been involved in radioactive waste dumping since the 1980s. Ships with toxic and radioactive waste were sunk off the Italian coast. In addition, vessels were allegedly sent to Somalia and other developing countries with toxic waste, including radioactive waste cargoes, which were either sunk with the ship or buried on land. The introduction of more rigorous environmental legislation in the 1980s made illegal waste dumping a lucrative business for organized crime groups in Italy. The phenomenon of widespread environmental crime perpetrated by criminal syndicates like the Camorra and 'Ndrangheta has given rise to the term "ecomafia".

Scientists uncover 'missing' plastics deep in the ocean
2/2/2022
FAU Scientists Uncover ‘Missing’ Plastics Deep in the Ocean
About 51 trillion microplastics are floating in the surface waters of oceans around the world. Originating from various types of plastics, these tiny fragments (less than 5 millimeters in length) pollute natural ecosystems. Hundreds of studies have surveyed plastic debris on the surface or near surface of the ocean. However, these studies only “scratch the surface,” and do not provide a complete inventory of what’s lurking beneath.
A study led by Florida Atlantic University is the first to unveil the prevalence of plastics in the entire water column of an offshore plastic accumulation zone in the southern Atlantic Ocean and implicates the ocean interior as a crucial pool of ‘missing’ plastics.
Results, published in the journal Global Change Biology , demonstrate that small microplastics are critical, underexplored and integral to the oceanic plastic inventory. In addition, findings show that weak ocean current systems contribute to the formation of small microplastics hotspots at depth, suggesting a higher encounter rate for subsurface particle feeders like zooplankton.
“Our study highlights the urgency for more quantification of the deep-ocean microplastics, especially the smaller size fraction, to better understand ecosystem exposure and to predict the fate and impacts of these microplastics,” said Tracy Mincer, Ph.D., senior author and an assistant professor of biology at FAU Harbor Branch Oceanographic Institute and FAU Harriet L. Wilkes Honors College.
To gain a better mechanistic understanding of how plastics sink from the ocean surface beyond the mixed layer and ultimately to abyssal depths of the ocean, the researchers sampled plastic particles in the South Atlantic Subtropical Gyre using in-situ high-volume filtration, Manta net and MultiNet sampling, combined with micro-Fourier-transform-infrared imaging.
They found that abundances and distribution patterns of small microplastics varied geographically and vertially due to the diverse and complex redistribution processes interacting with different plastic particles. They also observed large horizontal and vertical variations in the abundances of small microplastics, displaying inverse vertical trends in some cases. Small microplastics abundances in pump samples were more than two orders of magnitude higher than large microplastics concurrently collected in MultiNet samples.
“Small microplastics are different from large microplastics with respect to their high abundance, chemical nature, transport behavior, weathering stages, interactions with ambient environments, bioavailability and the release efficiency of plastic additives,” said Shiye Zhao, Ph.D., first author and a post-doctoral fellow at FAU Harbor Branch. “These distinct characteristics impact their environmental fate and potential impacts on marine ecosystems.”

Toxic Cookware
According
to risk assessments by the EPA, PFOA’s present significant
developmental and reproductive risks in humans with the use of Teflon:
An increased rate of birth defects has been found in mothers working at
DuPont. The company’s response was to move female employees to other
sections of the plant in an effort to reduce their exposure to PFOA’s.
The chemical coating is also used in fire fighting foam and phone
cables. Variants of FPOA’s are used to make the coating on stain
resistant carpets and flame retardants for clothing and computers.Teflon
can also be found in nail polish removers, eyeglasses, and as lining in
pizza boxes.
PFOA’s do not break down in the
environment anytime soon, causing forever pollution. According to Tim
Kropp, a toxicologist with the Environmental Working Group, if all
future exposure is cut off, it would take the body at least 20 years to
detoxify Teflon chemicals. Finally, the EPA has recommended that PFOA be
classified as a human carcinogen.
http://whatscookingamerica.net/LindaPosch/ToxicCookware.htm
______________
Teflon Is Forever
http://www.motherjones.com/environment/2007/05/teflon-forever -
Teflon,
it turns out, gets its nonstick properties from a toxic, nearly
indestructible chemical called pfoa, or perfluorooctanoic acid. Used in
thousands of products from cookware to kids' pajamas to takeout coffee
cups, pfoa is a likely human carcinogen, according to a science panel
commissioned by the Environmental Protection Agency. It shows up in
dolphins off the Florida coast and polar bears in the Arctic; it is
present, according to a range of studies, in the bloodstream of almost
every American—and even in newborns (where it may be associated with
decreased birth weight and head circumference). The nonprofit watchdog
organization Environmental Working Group (ewg) calls pfoa and its close
chemical relatives "the most persistent synthetic chemicals known to
man." And although DuPont, the nation's sole Teflon manufacturer, likes
to chirp that its product makes "cleanup a breeze," it is now becoming
apparent that cleansing ourselves of pfoa is nearly impossible. DuPont
has always known more about Teflon than it let on. Two years ago the epa
fined the company $16.5 million—the largest administrative fine in the
agency's history—for covering up decades' worth of studies indicating
that pfoa could cause health problems such as cancer, birth defects, and
liver damage. The company has faced a barrage of lawsuits and
embarrassing studies as well as an ongoing criminal probe from the
Department of Justice over its failure to report health problems among
Teflon workers. One lawsuit accuses DuPont of fouling drinking water
systems and contaminating its employees with pfoa. Yet it is still
manufacturing and using pfoa, and unless the epa chooses to ban the
chemical, DuPont will keep making it, unhindered, until 2015.
The
Teflon era began in 1938, when a DuPont chemist experimenting with
refrigerants stumbled upon what would turn out to be, as the company
later boasted, "one of the world's slipperiest substances." DuPont
registered the Teflon trademark in 1944, and the coating was soon put to
work in the Manhattan Project's A-bomb effort. But like other wartime
innovations, such as nylon and pesticides, Teflon found its true calling
on the home front. By the 1960s, DuPont was producing Teflon for
cookware and advertising it as "a housewife's best friend." Today,
DuPont's annual worldwide revenues from Teflon and other products made
with pfoa as a processing agent account for a full $1 billion of the
company's total revenues of $29 billion. Teflon is not actually the
brand name of a pan; it's the name of the slippery stuff that DuPont
sells to other companies. Marketers deploy the trademark as a
near-mystic incantation, a mantra for warding off filth:
Clorox
Toilet Bowl Cleaner With Teflon® Surface Protector, Dockers Stain
Defender™ With Teflon®, Blue Dolphin Sleep 'N Play layette set
"protected with Teflon fabric protector."
Breathing in
dust from Teflon-treated rugs or upholstery as they wear down is one
way we may be ingesting pfoa. Food is another: Pizza-slice paper,
microwave-popcorn bags, ice cream cartons, and other food packages are
often lined with Zonyl, another DuPont brand. Technically, Zonyl does
not contain pfoa, but it is made with fluorotelomer chemicals that break
down into pfoa. Regardless of how it gets into our bodies, once there,
pfoa stays—quietly accumulating in our tissues, for a lifetime.
Teflon
is not the only nonstick, non-stain brand that has turned out to be
stickier than advertised. Scotchgard and Gore-Tex, to name just two, are
also made with pfoa or other perfluorochemicals (pfcs). Last year the
epa hit the 3M corporation, maker of Scotchgard, with a $1.5 million
penalty for failing to report pfoa and pfc health data.
Chemicals similar to pfoa have recently turned up in water supplies of suburban Minneapolis and St. Paul, near 3M facilities.
Unlike
DuPont, though, 3M no longer sells pfoa: In the late 1990s, when
testing blood samples for a health study, the company found pfoa even in
the "clean" samples from various U.S. blood banks that it had planned
to use as controls. "They realized they were contaminating the entire
population," says Richard Wiles, the Environmental
Working Group's executive director. In 2000, 3M announced that it was discontinuing pfoa production.
When
3M got out, DuPont, which until then had bought its pfoa from 3M,
jumped in. Now the company's bottom line depends on whether its
product's mythic reputation—Teflon's own Teflon—remains intact.
So
far, it seems to be holding. Nonstick pots and pans account for 70
percent of all cookware sold. "Amazingly enough, all the publicity has
had no impact on sales," says Hugh Rushing, executive vice president of
the Cookware Manufacturers' Association.
"People read
so much about the supposed dangers in the environment that they get a
tin ear
In
fact, nonstick pans are not a major source of exposure to pfoa, because
almost all of the chemical is burned off during manufacture. Still,
when overheated, Teflon cookware can release trace amounts of pfoa and
14 other gases and particles, including some proven toxins and
carcinogens, according to the Environmental Working Group's review of 16
research studies over some 50 years. At 500 degrees, Teflon fumes can
kill birds; at 660, they can cause the flu-like "polymer fume fever" in
humans. Even at normal cooking temperatures, two of four brands of
frying pans tested in a study cosponsored by DuPont gave off trace
amounts of gaseous pfoa and other perfluorated chemicals.
A
$5 billion multistate class-action lawsuit representing millions of
Teflon cookware owners alleges that DuPont has known for years that its
coatings could turn toxic at temperatures commonly reached on the stove,
but failed to tell consumers. DuPont's website recommends not heating
Teflon above 500 degrees (so it doesn't "discolor or lose its nonstick
quality") and advises that when overheated, "nonstick cookware can emit
fumes that may be harmful to birds, as can any type of cookware
preheated with cooking oil, fats, margarine and butter." But who knows
how hot a pan gets, and who looks out for birds before fixing dinner?
Even while researching this story, I left a nonstick skillet on the
stove. The fumes smelled like fried computer, and I vowed not to do it
again. But I also decided to go with the hazardous-waste flow, figuring,
"We're all toxic dumps anyway." (ewg studies have found a "body burden"
of 455 industrial pollutants, pesticides, and other chemicals in the
bodies of ordinary Americans.) With toxic substances unavoidable, or at

DuPont's Teflon Cover-up
Mar. 22, 2006
https://environmentalchemistry.com/yogi/environmental/200603tefloncoverup.html
EPA Steps In
EPA has been conducting studies on C-8 or PFOA and have found that this man-made chemical (that is not found in nature) is present in just about every living or previously living thing in the industrialized world. In August of 2005 an independent EPA scientific advisory board concluded that PFOA is a likely human carcinogen and recommended that the EPA conduct cancer risk assessments for a variety of tumors that have been observed in rats and mice that were exposed to the chemical.
In December 2005 the EPA stated that DuPont had violated both the Resource Conservation and Recovery Act (RCRA) and the Toxic Substance Control Act (TSCA) for allegedly failing to file notification about the potential health and environmental risks posed by perfluorooctanoic acid, or PFOA (C-8). In the largest settlement ever made involving a civil administrative federal environmental statute in the history of EPA, the Environmental Protection Agency (EPA) announced that DuPont agreed to pay $10.25 million in fines and $6.25 million to fund environmental projects to settle allegations that the company withheld information about the dangers of the toxic chemical PFOA.
In addition, DuPont has already agreed to pay up to $343 million in settlement of a class action arising from the contamination of drinking water in Ohio and West Virginia from its plant near Parkersburg, West Virginia. DuPont will also set aside up to another $235 million for future medical monitoring if the studies find C-8 can make people sick.
Had it not been for the diligence of a "whistle blowing" employee at DuPont, the case might still have been unexposed. This makes one wonder it there are lots of other "C-8s" out there, different chemicals, created by companies other than DuPont, with dubious records, filed away in dusty research files marked "Personal and Confidential."

The Weinberg Group
- The Weinberg Group is a Washington, DC-based consulting group, specializing in "international scientific and regulatory consulting" and "help[ing] companies protect their product at every stage of its life." Founded in 1983, the firm assists pharmaceutical, pesticide, and chemical companies in regulatory affairs, litigation, and media work.
- In an article authored by Paul D. Thacker, Environmental Science & Technology reported that in April 2003, the Weinberg Group proposed a strategy to DuPont to help defuse the growing controversy over the health impacts of perfluorooctanoic acid (PFOA), a compound used to make Teflon. Weinberg's Vice-President of Product Defense, P.Terrence Gaffney, wrote, "DuPont must shape the debate at all levels." One of his suggested strategies was to facilitate the "publication of papers and articles dispelling the alleged nexus between PFOA and teratogenicity as well as other claimed harm."
Gaffney also proposed to "develop 'blue ribbon panels' of thought leaders on issues related to PFOA" and to "coordinate the publishing of white papers on PFOA, junk science and the limits of medical monitoring." DuPont confirmed that they had hired the Weinberg Group to help with "scientific third party experts." The five-page 2003 letter also states that the Weinberg Group "has helped numerous companies manage issues allegedly related to environmental exposures. Beginning with Agent Orange in 1983, we have successfully guided clients through myriad regulatory, litigation and public relations challenges posed by those whose agenda is to grossly over regulate, extract settlements from, or otherwise damage the chemical manufacturing industry."- http://en.wikipedia.org/wiki/Weinberg_Group

Cyclohexane
http://toxipedia.org/display/toxipedia/Cyclohexane
Cyclohexane (C6H12) is a naturally occurring chemical that is also produced synthetically
and used as a solvent in numerous industries. Acute exposure to large
doses can affect the nervous system, and cyclohexane is a mild eye and
skin irritant.
Uses
Cyclohexane
is a "high volume chemical" and more than 1 million pounds is produced
annually in the US. It is used to extrapolate vapor degreasing solvents
and as a solvent in certain industries including laboratory chemicals,
machinery manufacturing and repair, rubber manufacturing, nylon production, and varnish and solvents.
In the past, it was used in certain pesticides.
Environmental Effects
Cyclohexane
is released into the environment primarily as an air pollutant from
industrial sources. It breaks down easily into its component chemicals
and it does not bind well to soil, so it eventually enters the
groundwater. Cyclohexane has been observed to contribute to the
formation of photochemical smog when it reacts with certain other
chemicals (#EPA).

Fluorotelomer alcohol
http://en.wikipedia.org/wiki/Fluorotelomer_alcohol
Fluorotelomer alcohols, or FTOHs, are fluorotelomers with an alcohol functional group. They are volatile precursors to perfluorinated carboxylic acids, such as PFOA and PFNA, and other compounds.
Environmental and health concerns
Fluorotelomer alcohols are volatile and widely detected in air. Fluorotelomer alcohols can biodegrade to perfluorinated carboxylic acids that persist in the environment and are found in the blood serum of populations and wildlife, such as the toxic PFOA and PFNA. The fluorotelomer alcohols 6:2 FTOH and 8:2 FTOH have been found to be estrogenic.
The atmospheric oxidation of fluorotelomer alcohols can also result in anthropogenic perfluorinated carboxylic acids. In addition to perfluorinated carboxylic acids, fluorotelomer alcohols can degrade to form unsaturated carboxylic acids which have been detected in bottlenose dolphins. Fluorotelomer alcohols such as 4:2 FTOH, 6:2 FTOH, 8:2 FTOH, and 10:2 FTOH, have been identified as residuals in consumer products such as stain repellents, Zonyl FSE, and windshield wash, among others. The United States Environmental Protection Agency has asked eight chemical companies to reduce the amount of residuals, including fluorotelomer alcohols, from products.

Fluoride and Teflon, Stainmaster, Scotchgard and Gore-Tex
Two
items concerning the health concerns and scientific manipulations
surrounding fluorine-based products, Teflon, Stainmaster, Scotchgard and
Gore-Tex; "Results show Teflon chemicals found in babies' blood":
1) A good overview about PFCs, including contamination of water:
http://www.ewg.org/reports/pfcworld/
Introduction
-- Consumers instantly recognize them as household miracles of modern
chemistry, a family of substances that keeps food from sticking topots
and pans, repels stains on furniture and rugs, and makes the rain roll
off raincoats. Industry makes use of the slippery, heat-stable
properties of these same chemicals to manufacture everything from
airplanes and computers to cosmetics and household cleaners.
But in the past five years, the multi-billion dollar "perfluorochemical" (PFC)
industry,
which underpins such world-famous brands as Teflon, Stainmaster,
Scotchgard and Gore-Tex, has emerged as a regulatory priority for
scientists and officials at the U.S. Environmental Protection Agency
(EPA). The PFC family is characterized by chains of carbon atoms of
varying lengths, to which fluorine atoms are strongly bonded, yielding
essentially indestructible chemicals that until recently were thought to
be biologically inert. No one thinks so now.
A flood of disturbing scientific findings since
The U.S.
EPA peremptorily forced one member of this family off the market in
2000: PFOS, the active ingredient used for decades in the original
formulation of 3M's popular Scotchgard stain and water repellent.
Shortly thereafter, 3M also stopped manufacture of a related
perfluorochemical, called PFOA, that is now under intense regulatory
pressure at EPA. 3M formerly sold PFOA to DuPont, which has used PFOA
for half a century in the manufacture of Teflon. (DuPont now now makes
the chemical itself at a new facility in North Carolina.) Alarmed by
findings from toxicity studies and by the presence of PFOA in the blood
of more than 90 percent of the U.S. population, EPA is expected to
announce initial steps to regulate the chemical in early April (2003).
This
report provides the first, comprehensive review ever published of the
pollution and health risks posed by PFCs, with special reference to
PFOA. It is based on a review of 50,000 pages of regulatory studies and
government documents obtained from EPA;
internal documents from DuPont and 3M disclosed in ongoing litigation; and an
examination of a growing body of independent studies on the toxicity and environmental occurrence of PFCs.
This
report also explains how major companies like 3M and DuPont, who
endlessly boast about their scientific prowess, could get away with
permanently contaminating the entire planet for decades amid assurance
from the chemical industry that it practices "responsible care" with
respect to public health and the environment.

PET plastic
( Polyethylene terephthalate )
https://en.wikipedia.org/wiki/PET_plastic
PET
was patented in 1941 by John Rex Whinfield, James Tennant Dickson and
their employer the Calico Printers' Association of Manchester. E. I.
DuPont de Nemours in Delaware, USA, first used the trademark Mylar
in June of 1951 and received registration of it in 1952. It is still the
most well known name used for polyester film. The current owner of the
trademark is Dupont Teijin Films US, a partnership with a Japanese
company.
Degradation
PET is subjected to various types of degradations during processing. The main
degradations that can occur are hydrolytic, thermal and, probably most important,
thermal
oxidation. When PET degrades, several things happen: discoloration,
chain scissions resulting in reduced molecular weight, formation of
acetaldehyde, and cross-links ("gel" or "fish-eye" formation).
Discoloration is due to the formation of various chromophoric systems
following prolonged thermal treatment at elevated temperatures.
This
becomes a problem when the optical requirements of the polymer are very
high, such as in packaging applications. The thermal and
thermooxidative degradation results in poor processibility
characteristics and performance of the material
Acetaldehyde
Acetaldehyde
is a colorless, volatile substance with a fruity smell. Although it
forms naturally in some fruit, it can cause an off-taste in bottled
water. Acetaldehyde forms by degradation of PET through the mishandling
of the material. High temperatures, (PET decomposes above 300 °C or 570
°F), high pressures, extruder speeds (excessive shear flow raises
temperature), and long barrel residence times all contribute to the
production of acetaldehyde. When acetaldehyde is produced, some of it
remains dissolved in the walls of a container and then diffuses into the
product stored inside, altering the taste and aroma. This is not such a
problem for non-consumables (such as shampoo), for fruit juices (which
already contain acetaldehyde), or for strong-tasting drinks like soft
drinks. For bottled water, however, low acetaldehyde content is quite
important, because, if nothing masks the aroma, even extremely low
concentrations (10–20 parts per billion in the water) of acetaldehyde
can produce an off-taste.
Safety
Commentary
published in Environmental Health Perspectives in April 2010 suggested
that PET might yield endocrine disruptors under conditions of common use
and recommended research on this topic. Proposed mechanisms include
leaching of phthalates as well as leaching of antimony. Article
published in Journal of Environmental Monitoring in April 2012 concludes
that antimony concentration in deionized water stored in PET bottles
stays within

Be cautious of water resistant clothing with PFCs
What are PFCs - http://www.everydayexposures.com/toxins/pfcs
Perfluorinated
Compounds (PFCs) are organofluorine compounds that have an ability to
make products stain, grease, and water resistant, and are popular for
their non-stick and stain-repellant uses. Due to these properties, PFCs
are often used in paper food containers such as microwave popcorn bags
and fast food wrappers. PFCs are considered persistent organic
pollutants (POPs) and resist chemical, biological, and photolytic
degradation in the environment. These chemicals biomagnify in the food
chain and bioaccumulate in animal and human tissues.

SILK SCREEN PRINTING
http://www.uic.edu/sph/glakes/harts1/HARTS_library/silkscrn.txt
Silk screen printing is one of the most hazardous processes in the arts and crafts.
Dermatitis, narcosis (dizziness, light-headedness, fatigue, nausea, lack of
coordination
and headaches), eye irritation, adverse reproductive hazards including
increased risk of miscarriage, and serious neurological problems can all
result from the processes of screen printing.
Traditionally,
silk screen printing has been performed using organic solvent-based
materials. Water-based inks containing less hazardous ingredients
provide a safer and increasingly popular alternative.
Many
silk screen inks contain many hazardous chemicals and solvents. Poster
inks can contain toluene and xylene, which are highly toxic aromatic
hydrocarbons, and large amounts of mineral spirits. Other inks, e.g.
vinyl inks, can contain large amounts of other highly toxic solvents,
for example, isophorone

Organic Screen Printing
http://organic.lovetoknow.com/Organic_Screen_Printing
Organic
screen printing is an important thing to consider when you are out
shopping for organic clothing. Even though you may be purchasing an
organic shirt, if it is printed with toxic inks you may not be doing as
much for the environment as you think. The good news is there are
earth-friendly screen printing methods that are a good choice over
traditional screen printing methods.
Traditional printing ink poses a serious danger to the air we breathe, the water we
drink
and the food we eat. This is because toxic chemicals that are produced
during the manufacturing and disposal processes, as well as during the
use of this ink, are released into the environment.
Plastisol, the traditionally used ink for screen printing, is manufactured by using a liquefied
form of polyvinyl chloride, or PVC. The chlorine-based chemicals that
are formed when this product is manufactured react with other chemicals
to create dioxins, PCBs and other toxic compounds. In addition, the
plasticizers used to make this ink flexible are carcinogenic and
continue to be released even after you have purchased the product. So
even if you have purchased an organic hemp or cotton shirt, your
purchase may not be as environmentally friendly as you think it is.

How Green Are Your Jeans?
Some 450 million pairs of jeans are sold in the United States each year -- 1.5 pairs for every man, woman, and child. The average woman has eight pairs in her closet. Chances are that to make those jeans, cotton crops were drenched in pesticides; fibers were stained with toxic dyes; and the resulting fabric was sandblasted, chemically softened, and ripped and scrunched to create the wrinkles and tears that make new jeans look perfectly broken in.
There is another option: the eco-minded can invest in a pair of jeans woven from organic cotton, dyed with natural indigo, and faded with nontoxic ozone.

Indigo dye
In 1897, 19,000 tons of indigo were produced from plant sources. Largely due to advances in organic chemistry,
production by natural sources dropped to 1,000 tons by 1914 and
continued to contract. These advances can be traced to 1865 when the
German chemist Adolf von Baeyer
began working on the synthesis of indigo. He described his first
synthesis of indigo in 1878 (from isatin) and a second synthesis in 1880
(from 2-nitrobenzaldehyde). The vinyl group can be oxidized in a number of different ways to yield 2-nitrobenzaldehyde.
The synthesis of indigo remained impractical, so the search for alternative starting materials at BASF and Hoechst continued. The synthesis of N-(2-carboxyphenyl)glycine from the easy to obtain aniline
provided a new and economically attractive route. BASF developed a
commercially feasible manufacturing process that was in use by 1897. In
2002, 17,000 tons of synthetic indigo were produced worldwide.

______________
Styrene
Styrene is regarded as a "hazardous chemical",
especially in case of eye contact, but also in case of skin contact, of
ingestion and of inhalation, according to several sources. Styrene is largely metabolized into styrene oxide in humans, resulting from oxidation by cytochrome P450. Styrene oxide is considered toxic, mutagenic, and possibly carcinogenic. Styrene oxide is subsequently hydrolyzed in vivo to styrene glycol by the enzyme epoxide hydrolase. The U.S. Environmental Protection Agency
(EPA) has described styrene to be "a suspected toxin to the
gastrointestinal tract, kidney, and respiratory system, among others." On 10 June 2011, the U.S. National Toxicology Program has described styrene as "reasonably anticipated to be a human carcinogen". However, a STATS author describes
a review that was done on scientific literature and concluded that "The
available epidemiologic evidence does not support a causal relationship
between styrene exposure and any type of human cancer". Despite this claim, work has been done by Danish researchers to
investigate the relationship between occupational exposure to styrene
and cancer. They concluded, "The findings have to be interpreted with
caution, due to the company based exposure assessment, but the possible
association between exposures in the reinforced plastics industry,
mainly styrene, and degenerative disorders of the nervous system and
pancreatic cancer, deserves attention". The Danish EPA recently concluded that the styrene data do not support a cancer concern for styrene.
The U.S. EPA does not have a cancer classification for styrene,
but currently is evaluating styrene's cancer-causing potential through
its EPA|Integrated Risk Information System (IRIS) program. The U.S. National Toxicology Program of the U.S. Department of Health and Human Services also currently is evaluating styrene's potential toxicity
To date, no regulatory body anywhere in the world has classified
styrene as a known human carcinogen, although several refer to it in
various contexts as a possible or potential human carcinogen. The International Agency for Research on Cancer considers styrene to be "possibly carcinogenic to humans". Chronic exposure to styrene leads to tiredness/lethargy, memory deficits, headaches and vertigo.

Are You or Your Family Eating Toxic Food Dyes?
2011
Food dyes are one of the most widely used and dangerous additives.
While the European Union has recently placed regulations on labeling
food dyes to inform consumers of the health risks, the United States has
no such requirement.
Here are some of the most common food dyes used today, according to the Food Freedom Network:
- Blue #1 (Brilliant Blue)
An unpublished study suggested the possibility that Blue 1 caused kidney tumors in mice. What it's in: Baked goods, beverages, desert powders, candies, cereal, drugs, and other products. - Blue #2 (Indigo Carmine)
Causes a statistically significant incidence of tumors, particularly brain gliomas, in male rats. What it's in: Colored beverages, candies, pet food, & other food and drugs. - Citrus Red #2
It's toxic to rodents at modest levels and caused tumors of the urinary bladder and possibly other organs. What it's in: Skins of Florida oranges. - Green #3 (Fast Green)
Caused significant increases in bladder and testes tumors in male rats. What it's in: Drugs, personal care products, cosmetic products except in eye area, candies, beverages, ice cream, sorbet, ingested drugs, lipsticks, and externally applied cosmetics. - Red #3 (Erythrosine)
Recognized in 1990 by the FDA as a thyroid carcinogen in animals and is banned in cosmetics and externally applied drugs. What it's in: Sausage casings, oral medication, maraschino cherries, baked goods, and candies. - Red #40 (Allura Red)

Blue Dye Is More Toxic To Our Health Than We Thought
After evaluating the health consequences of using this blue dye, they found that it could be seeping into our bloodstream and destroying our gastrointestinal system. In addition, there are concerns that it could inhibit cell respiration, which could lead to ADHD, allergies and asthma. And, when Brilliant Blue was used in feeding tubes, a 2003 study proved that it had links to blue-tinged skin, urine, and feces, as well as hypotension and even death.
Why is this dye so harmful? The researchers say it can get into our bloodstream when the skin’s barrier is vulnerable (like after shaving) or when the dyes are put onto the mucous membrane of the tongue (like from a lollypop).
So why is it still legal to put in our food and cosmetics?
It shouldn’t be, say the researchers. They concluded that it should be banned at least from things like hard candies (which sit on the tongue and expose us to more dye absorption) and certain cosmetics. Will that happen? Probably not anytime soon because, of course, the Association of Color Manufacturers disagree with this study.

Carcinogenic Chemical: Disperse Blue 1
2011
Disperse
Blue 1 is reasonably anticipated to be a human carcinogen based on
evidence of malignant tumor formation in experimental animals to an
unusual degree with regard to incidence, site, and type of tumor (NTP
1986), and because it is an anthraquinone and therefore, structurally
related to other substances listed in a previous Annual Report on
Carcinogens as either known to be human carcinogens or reasonably
anticipated to be human carcinogens (NTP 1994).
"Over 3 million people in the United States use hair color preparations containing
Disperse
Blue 1 in semipermanent hair color formulations at concentrations of
less than 1%. Disperse Blue 1 has been used as a fabric dye for nylon,
cellulose acetate and triacetate, and polyester. It has also been used
for surface dyeing of thermoplastics and as a solvent dye in cellulose
acetate plastics. Disperse Blue 1 is also used to dye fur, sheepskins,
acetate, nylon, and other synthetic fibers (NTP 1986, IARC 1990, HSDB
2001)."

in Critically Ill Patients
The addition of dye, particularly Food Drug and Cosmetic Blue No. 1 (FD&C Blue No. 1), to enteral feedings is commonly employed for the detection of aspiration in the critical care setting. However, evidence suggests that this dye is potentially toxic under some clinical conditions. In contrast to early investigations demonstrating limited absorption of FD&C Blue No. 1 when administered to healthy animals, significant absorption of the dye has been reported in critically ill patients, presumably due to disruption of the integrity of the intestinal

Some people will debate the various
outcomes of medical experiments used with many chemicals. This would
include the toxicity of many synthetic dyes, including blue dyes such
as " Coomassie Brilliant Blue - http://en.wikipedia.org/wiki/Brilliant_Blue_G ."
Coomassie Brilliant Blue is being used for medicinal purposes for spinal injuries.
Coomassie Brilliant Blue is not to be confused with Brilliant Blue FCF (Blue 1) - http://en.wikipedia.org/wiki/Brilliant_Blue_FCF
______________
Blue food dye reduces paralysis from spinal injuries - but turns you blue
I'll admit a personal interest in this story: two years ago, a friend
of mine, Lenna, had a nasty motorcycle accident, and I was present at
the scene. It was clear she had spinal injuries - her back was twisted
fairly badly. But she was able to move her feet and wiggle her toes, so
we held out hope that the injury wouldn't be too severe.
As it turned out, she became a paraplegic, with virtually no feeling
or movement below her navel. The original injury, as it turns out, does a
certain amount of damage to the spinal cord - but the major, unfixable
damage is done over the next few hours and days.
Much of this is because of a chemical called adenosine triphosphate,
or ATP. ATP is used as a kind of cellular battery to deliver energy to
cells around the body in normal life. But in the event of spinal trauma,
the area around the injury is flooded with ATP, which causes otherwise
healthy neurons to fire like crazy until they burn themselves out and
die. It also increases the swelling around the wound. Swelling around an
injury site is a positive healing factor in most parts of the body, but
the spinal cord lives in a tightly enclosed column of bone, and the
swelling, on top of the bleeding from the trauma, can cut off oxygen
supply to the lower spinal cord.
In effect, a patient might receive a spinal injury of low or medium
severity - but the actions of ATP in the hours and days after the trauma
can completely destroy the function of the spinal cord, leaving
patients paralyzed. This is exactly what happened to Lenna.
But a study published in July 28's Proceedings of the National Academy of Sciences (PNAS)
seems to show that it's possible to block the actions of ATP and
greatly reduce the severity and permanence of spinal injuries - using
the same type of food dye that gives blue M&Ms their color, a food
dye called Brilliant Blue G, or BBG.
BBG can be administered intravenously - so there's no need to inject
directly into the injury site - and it has the ability to cross the
blood-brain barrier, which gives it access to the spinal cord. It
happens to bind to the same neuroreceptor (P2X7) as the ATP binds to -
but it has a stronger affinity for the receptor than ATP has - so it
effectively blocks the action of the ATP at the injury site.

Cosmetics and Fragranced Products Pose High Risks for Breast Cancer and Other Illnesses
Makeup kits in department stores typically contain, in varying

cream, body and shower gel, powder blusher, perfume spray, skin cream,
hand lotion, eyebrow pencil, moisturizers, lip gloss and brushes. The
cosmetic give-away initiative is very popular among breast cancer
survivors. I have read reports of some women driving over 100 miles

New fear about food dyes
The research team, out of the Slovak University of Technology, studied two blue dyes, Patent Blue and Brilliant Blue. The former is banned from food products in the United States, but Brilliant Blue (also known as FD&C Blue No. 1) is used in food, textiles, leathers, and cosmetics in several countries including the U.S.
Hojerová and her colleagues have shown that the dyes can actually enter the bloodstream via the skin or through the digestive tract. That’s a major surprise, because it was believed that the skin blocked the dye from seeping into the body, and that ingested dyes were destroyed by the gastrointestinal system.
The team reached their conclusions by studying pig tongues coated
with human saliva: Brilliant Blue and Patent Blue dye were placed on the
tongues for 20 minutes, in an effort to mimic licking a lollipop. One
day later, the team found that both dyes had actually been absorbed
through the tongue and into the bloodstream, with Patent Blue
penetrating to a greater extent.

Health Hazard Alert-- Benzidine-, o-Tolidine-, and o-Dianisidine- Based Dyes
Recent
data from animal tests, case reports, and other sources about the
carcinogenic effects and metabolism of benzidine-, o-tolidine-, and o-
dianisidine-based dyes have come to the attention of OSHA and NIOSH.
Both agencies have reviewed the data and conclude that the findings
establish the potential of these dyes to cause cancer in humans.
OSHA
and NIOSH conclude that persons working with these dyes should be aware
of the potential health hazards that could result from excessive
exposure to them. The intent of this document is to summarize the
information available of the carcinogenic effects and metabolism of
benzidine-, o-tolidine-, and o- dianisidine-based dyes and to provide
guidance so that employers, employees, and physicians may work together
to reduce potential health hazards that could result from excessive
exposure to these dyes.
Metabolism of Benzidine-Based Dyes to Benzidine Evidence exists to indicate that
benzidine-based dyes are converted to the carcinogen benzidine in
laboratory animals and in humans. The NCI bioassay of C.I. Direct Blue
6, C.I. Direct Black 38, and C.I. Direct Brown 95 for carcinogenicity
included analyses of urine samples for benzidine from treated animals.
Urine samples from Fischer 344 rats were collected over 24-hour periods
during weeks 4 and 12. Benzidine was detected in the urine of rats given
benzidine-based dyes but not in the urine of the untreated control
rats. As the amount of the dye fed to the rats increased, so did the
amount of benzidine excreted in the urine. Analyses of the dyes prior to
mixing in feed demonstrated no residual or contaminating benzidine. The
data indicate that the benzidine in the urine resulted from the
bio-transformation of the dyes. Similar results were found by analyses
of urine from B6C3F1 mice.
Rinde and Troll studied the metabolism of the benzidine-based dyes C.I. Direct Blue 6, C.I. Direct
Black 38, C.lI. Direct Brown 95, and C.I. Direct Red 28 in Rhesus
monkeys. Each monkey was gavaged with a single dose of one dye dissolved
in dimethyl sulfoxide. Each of the dyes was administered in two
different dose levels in separate experiments, except for C.I. Direct
Red 28, which was given at only one level. Purified benzidine was
administered at two levels in the same manner. Urine was collected over a
72-hour period from all the animals and pooled for assay. Urine
collected from the monkeys before dosing was used to establish the
control values. The authors found benzidine and a metabolite, monoacetyl
benzidine, in the urine of the monkeys receiving the dyes. The control
values were negative. They concluded that the dyes were converted to
benzidine in vivo. Korosteleva et al. found benzidine in the blood
serum and tissues of rats fed Direct Red 13. This indicated that the dye
had been converted to benzidine. Lynn et al. reported on the metabolism
of the benzidine-based dyes C.I. Direct Blue 2, C.I. Direct Black 4,
C.I. Direct Brown 2, C.I. Direct Orange 1. C.I. Direct Red 28, C.I.
Direct Orange 8, and C.I. Direct Green 1 in female mongrel dogs and
rats. Each of five mongrel dogs was administered a dye orally and urine
was collected at 24 hour intervals for 3 days. No trace of benzidine was
detected in the dogs' urine 3 days after exposure. Some dogs were used
more than once with a minimum of 1 week between dye exposures. Benzidine
was recovered in the urine of each treated dog following the oral
administration of the 7 dyes. Although some residual benzidine in each
of the dyes had been detected prior to administration according to the
authors, the amount of benzidine recovered in the urine exceeded that
administered as a contaminant by at least 9 times. These finding suggest
the dye was converted to benzidine in the dog.

Tattoo ink - http://en.wikipedia.org/wiki/Tattoo_ink
Manufacturers are not required to reveal their ingredients or conduct trials, and recipes may be proprietary. Professional inks may be made from iron oxides (rust), metal salts, plastics. Homemade or traditional tattoo inks may be made from pen ink, soot, dirt, blood, or other ingredients.
Heavy metals used for colors include mercury (red); lead (yellow, green, white); cadmium (red, orange, yellow); nickel (black); zinc (yellow, white); chromium (green); cobalt (blue); aluminium (green, violet); titanium (white); copper (blue, green); iron (brown, red, black); and barium (white). Metal oxides used include ferrocyanide and ferricyanide (yellow, red, green, blue). Organic chemicals used include azo-chemicals (orange, brown, yellow, green, violet) and naptha-derived chemicals (red). Carbon (soot or ash) is also used for black. Other compounds used as pigments include antimony, arsenic, beryllium, calcium, lithium, selenium, and sulphur.
Tattoo ink manufacturers typically blend the heavy metal pigments
and/or use lightening agents (such as lead or titanium) to reduce
production costs.

How toxic is Halloween face paint on your child’s face?
2011
http://www.berkeleyside.com/2011/10/28/toxicity-of-halloween-face-paint-concerns-some-parents/
The
other thing that surprised me is how few Berkeleyans seem to know about
this. Even Berkeley independent kids’ stores are selling these toxic
brands, which include Alex Face Paint, which had the highest lead
quantity of the ten face paints in the study.
Just
this weekend my daughter was painted by “Snazaroo” face paint at a
family fair down the street from our home. I assumed that the face paint
used would be a safe brand given that it was a local Berkeley event,
but when I got home I looked up Snazaroo. The CSC report said it
contained lead, nickel and cobalt. Lead can lead to a low blood count
(anemia). Small amounts of lead in the body can make it hard for
children to learn, pay attention, and succeed in school.
Higher amounts of lead exposure can damage the nervous system, kidneys,
and other major organs. Very high exposure can lead to seizures or
death.

What's in Fast Food Chicken? (Hint: It’s NOT Chicken)
2018
Frying chicken is fairly simple, if a little messy. You dip pieces of
chicken into a mix of egg and milk, roll them around in flour and
spices, then cook the chicken in sizzling hot oil until the pieces are
brown, crispy and delicious.
But wait! Don’t forget to add a dash of dimethylpolysiloxane, an anti-foaming agent made of silicone that is also used in Silly Putty and cosmetics.
Now add a heaping spoonful of tertiary butylhydroquinone
(TBHQ), which is a chemical preservative and a form of butane (AKA
lighter fluid). One gram of TBHQ can cause “nausea, vomiting, ringing in
the ears, delirium, a sense of suffocation, and collapse,” according to
A Consumer’s Dictionary of Food Additives. Five grams of TBHQ can kill you. Sprinkle on thirteen other corn-derived ingredients, and you’re only
about twenty shy as many ingredients as a single chicken nugget from
McDonald’s. And you were using pulverized chicken skin and mechanically reclaimed meat for your chicken, right?

Subway sandwich chain to remove chemical found in yoga mats from bread
February 6, 2014
Subway confirmed on Thursday that they were
removing a chemical used to make yoga mats and rubber soles on shoes from their sandwich bread.
“We are already in the process of removing azodicarbonamide as part of
our bread improvement efforts despite the fact that it is a USDA and FDA
approved ingredient,” Subway told CBS News via e-mail. “The complete conversion
to have this product out of the bread will be done soon.”
The fact that azodicarbonamide was used as an ingredient in
U.S. and Canadian Subway products was brought to light by FoodBabe.com blogger Vani Hari. Hari claims the chemical can be found in 9-grain wheat, Italian white,
honey oat, Italian herbs & cheese, parmesan/oregano, roasted garlic, sourdough
and Monterrey cheddar breads.
She launched a petition asking the sandwich chain to remove azodicarbonamide
from their menu items, pointing out that Australia and Europe have banned the
chemical over health concerns. Subway does not use azodicarbonamide in their bread recipes in those countries.

Lanxess AG is a specialty chemicals group based in Germany, with headquarters and major operations in Cologne. It was founded in 2004 when Bayer AG spun
off its chemicals operations and parts of its polymer activities. As
measured by sales, Lanxess is the fourth-largest chemicals group in
Germany. The company's principal product areas are in chemicals, rubber and plastics.
Lanxess traces its roots to 1863, the year in which Friedrich Bayer & Co. was founded as a manufacturer of synthetic dyestuffs.
In 2004, Bayer, seeking to focus its business on healthcare and
nutrition, spun off most of its chemicals business and roughly one-third
of its polymers business into an independent subsidiary named Lanxess.
Shares in Lanxess AG began to trade on the Frankfurt Stock Exchange on
January 31, 2005, at which time each shareholder of Bayer was issued one
share of stock in Lanxess.

Azodicarbonamide
Azodicarbonamide, or azobisformamide, is a chemical compound with the molecular formula C2H4O2N4. It is a yellow to orange red, odorless, crystalline powder. As a food additive, it is known by the E number E927.
Azodicarbonamide as a blowing agent in plastics has been banned in
Europe since August 2005 for the manufacture of plastic articles that
are intended to come into direct contact with food.
In the United States, azodicarbonamide has generally recognized as safe (GRAS) status and is allowed to be added to flour at levels up to 45 ppm.
In the UK, the Health and Safety Executive
has identified azodicarbonamide as a respiratory sensitizer (a possible
cause of asthma) and determined that products should be labeled with
"May cause sensitisation by inhalation." The World Health Organization
has linked azodicarbonamide to "respiratory issues, allergies and
asthma" for individuals at workplaces where azodicarbonamide is
manufactured. The available data are restricted to these occupational
environments. Exposure of the general public to azodicarbonamide could
not be evaluated because of the lack of available data.

Perfluorooctanesulfonic acid (PFOS)
Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS), is a man-made fluorosurfactant and global pollutant. PFOS was the key ingredient in Scotchgard, a fabric protector made by 3M, and numerous stain repellents. It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. PFOS can form from the degradation of precursors in addition to industrial production. The PFOS levels that have been detected in wildlife are considered high enough to affect health parameters, and recently higher serum levels of PFOS were found to be associated with increased risk of chronic kidney disease in the general US population, consistent with earlier animal studies. "This association was independent of confounders such as age, sex, race/ethnicity, body mass index, diabetes, hypertension, and serum cholesterol level."
Threat to people and wildlife
According to a study by the Environmental Directorate of the OECD "PFOS is persistent, bioaccumulative and toxic to mammalian species."

Thermal plasma technology for radioactive waste treatment: a review
08 July 2020
Abstract
In
this paper, a review of radioactive wastes treatment using thermal
plasma technology is presented as a treatment method for radioactive
waste management. Virtually all waste streams can be treated by the
thermal plasma technologies, resulting in a conditioned product, free
from organics and liquids, definitely meeting the acceptance criteria
for safe storage and disposal. The application of the thermal plasma
system in the nuclear area is still one of the current research topics
due to the theoretical and practical complexity of the treatment. This
paper discusses the performance of the thermal plasma systems,
addressing the advantages and limitations of the method.

Graphite electrode DC arc furnace. Innovative technology summary report
1995
Abstract
The
Graphite Electrode DC Arc Furnace (DC Arc) is a high-temperature
thermal process, which has been adapted from a commercial technology,
for the treatment of mixed waste. A DC Arc Furnace heats waste to a
temperature such that the waste is converted into a molten form that
cools into a stable glassy and/or crystalline waste form. Hazardous
organics are destroyed through combustion or pyrolysis during the
process and the majority of the hazardous metals and radioactive
components are incorporated in the molten phase. The DC Arc Furnace
chamber temperature is approximately 593--704 C and melt temperatures
are as high as 1,500 C. The DC Arc system has an air pollution control
system (APCS) to remove particulate and volatiles from the offgas. The
advantage of the DC Arc is that it is a single, high-temperature thermal
process that minimizes the need for multiple treatment systems and for
extensive sorting/segregating of large volumes of waste. The DC Arc has
the potential to treat a wide range of wastes, minimize the need for
sorting, reduce the final waste volumes, produce a leach resistant waste
form, and destroy organic contaminants. Although the DC arc plasma
furnace exhibits great promise for treating the types of mixed waste
that are commonly present at many DOE sites, several data and technology
deficiencies were identified by the Mixed Waste Focus Area (MWFA)
regarding this thermal waste processing technique. The technology
deficiencies that have been addressed by the current studies include:
establishing the partitioning behavior of radionuclides, surrogates, and
hazardous metals among the product streams (metal, slag, and offgas) as
a function of operating parameters, including melt temperature, plenum
atmosphere, organic loading, chloride concentration, and particle size;
demonstrating the efficacy of waste product removal systems for slag and
metal phases; determining component durability through test runs of
extended duration, evaluating the effect of feed composition variations
on process operating conditions and slag product performance; and
collecting mass balance and operating data to support equipment and
instrument design.

Plasma arc recycling
June 19, 2023
Humans are machines for turning the world into waste—at least that's how it seems. On average, every single person in the United States produces about 2kg (5lb) of trash per day, which adds to up three quarters of a ton, per person, each year! What are we to do with all this junk? Recycling is one option, but not everyone does it and there are lots of things (such as electronic circuit boards) made from multiple materials that cannot be easily broken down and turned into new things. That's why much of our waste goes where it's always gone, buried beneath the ground. But we're running out of landfill space too—and that problem is bound to get worse. Another possibility is to incincerate waste, as though it were a fuel, and use it to produce energy, but incinerators are deeply unpopular with local communities because of the air pollution they can produce.
A relatively new type of waste treatment called plasma arc recycling (sometimes referred to as "plasma recycling," "plasma gasification," "gas plasma waste treatment," "plasma waste recycling," and various other permutations of the words plasma, gas, arc, waste, and recycling) aims to change all this. It involves heating waste to super-high temperatures to produce gas that can be burned for energy and rocky solid waste that can be used for building. Supporters claim it's a cleaner, greener form of waste treatment, but opponents argue it's simply old-fashioned incineration dressed up in new clothes. What exactly does plasma recycling involve? Let's take a closer look!
https://www.explainthatstuff.com/plasma-arc-recycling.html
______________
Plasma arc gasification
https://www.britannica.com/technology/plasma-arc-gasification
plasma
arc gasification (PAG), waste-treatment technology that uses a
combination of electricity and high temperatures to turn municipal waste
(garbage or trash) into usable by-products without combustion
(burning). Although the technology is sometimes confused with
incinerating or burning trash, plasma gasification does not combust the
waste as incinerators do. Instead, it converts the organic waste into a
gas that still contains all its chemical and heat energy and converts
the inorganic waste into an inert vitrified glass called slag. The
process can reduce the volume of waste sent to landfills and generate
electricity.
Process
In the PAG process an electrical arc
gasifier passes a very high voltage electrical current through two
electrodes, creating an arc between them. Inert gas, which is under high
pressure, then passes through the electrical arc into a sealed
container (called a plasma converter) of waste materials. Temperatures
in the arc column can reach more than 14,000 °C (25,000 °F), which is
hotter than the surface of the Sun. Exposed to such temperatures, most
waste is transformed into gas consisting of basic elements, while
complex molecules are torn apart into individual atoms.
The by-products of plasma arc gasification consist of the following:
Syngas, which is a mixture of hydrogen and carbon monoxide. Waste
materials, including plastics, contain high amounts of hydrogen and
carbon monoxide, and the conversion rate of those materials into syngas
can exceed 99 percent. Before the syngas can be used for power, it must
be cleansed of harmful materials such as hydrogen chloride. Once
cleaned, the syngas can be burned like natural gas, with a portion going
to power the plasma arc gasification plant and the remainder being sold
to utility companies, which also use it primarily for producing
electricity.
Slag, which is a solid residue resembling obsidian,
can be cleaned of contaminants, including heavy metals such as mercury
and cadmium, and processed into bricks and synthetic gravel.
Residual heat, which emanates from the process and can be used to produce steam for electrical generation.
The
composition of the waste stream can affect the effectiveness of the
gasification procedure. Garbage that is high in inorganic materials,
such as metals and construction waste, will yield less syngas, which is
the most-valuable by-product, and more slag. For that reason, it may be
worthwhile in certain settings to presort the waste stream. If waste can
be shredded before it enters the gasification chamber, the efficiency
of the PAG is improved.

Plasma methods for metals recovery from metal–containing waste
2018
Abstract
Metal–containing
waste, a kind of new wastes, has a great potential for recycling and is
also difficult to deal with. Many countries pay more and more attention
to develop the metal recovery process and equipment of this kind of
waste as raw material, so as to solve the environmental pollution and
comprehensively utilize the discarded metal resources. Plasma processing
is an efficient and environmentally friendly way for metal–containing
waste. This review mainly discuss various metal–containing waste types,
such as printed circuit boards (PCBs), red mud, galvanic sludge, Zircon,
aluminium dross and incinerated ash, and the corresponding plasma
methods, which include DC extended transferred arc plasma reactor, DC
non-transferred arc plasma torch, RF thermal plasma reactor and argon
and argon–hydrogen plasma jets. In addition, the plasma arc melting
technology has a better purification effect on the extraction of useful
metals from metal–containing wastes, a great capacity of volume
reduction of waste materials, and a low leaching toxicity of solid slag,
which can also be used to deal with all kinds of metal waste materials,
having a wide range of applications.

The electrified commercial cement kiln
06 January 2023
Summary
Kiln
electrification will only form one part of the possible solutions for a
decarbonised cement industry. The electrified kiln would cut CO2
emissions which would be a huge saving for EU cement producers looking
at approximately EUR75/t of CO2 emission charges. Battery storage could
well be required to enhance the electric kiln and to optimise usage at
peak electricity tariff usage periods. It is with such methods that the
cement industry might not only achieve decarbonisation but could also
achieve the necessary six per cent rise in cement production to meet the
growing cement demand expected from larger populations by 2050.

April 7, 2021
Abstract
Nonthermal
atmospheric pressure biocompatible plasma (NBP), alternatively called
bio-cold plasma, is a partially ionized gas that consists of charged
particles, neutral atoms and molecules, photons, an electric field, and
heat. Recently, nonthermal plasma-based technology has been applied to
bioscience, medicine, agriculture, food processing, and safety. Various
plasma device configurations and electrode layouts has fast-tracked
plasma applications in the treatment of biological and material
surfaces. The NBP action mechanism may be related to the synergy of
plasma constituents, such as ultraviolet radiation or a reactive
species. Recently, plasma has been used in the inactivation of viruses
and resistant microbes, such as fungal cells, bacteria, spores, and
biofilms made by microbes. It has also been used to heal wounds,
coagulate blood, degrade pollutants, functionalize material surfaces,
kill cancers, and for dental applications. This review provides an
outline of NBP devices and their applications in bioscience and
medicine. We also discuss the role of plasma-activated liquids in
biological applications, such as cancer treatments and agriculture. The
individual adaptation of plasma to meet specific medical requirements
necessitates real-time monitoring of both the plasma performance and the
target that is treated and will provide a new paradigm of plasma-based
therapeutic clinical systems.

Observation of magnet-induced star-like radiation of a plasma created from cancer cells in a laser trap
2024 Mar 7
Abstract
We
present a new phenomenon resulting from the interaction of magnetic
beads with cancer cells in a laser trap formed on a slide containing a
depression 16.5 mm in diameter and 0.78 mm of maximum depth. This
phenomenon includes the apparent formation and expansion of a dark
bubble that attracts and incinerates surrounding matter when it
explodes, which leads to a plasma emitting intense radiation that has
the appearance of a star on a microscopic scale. We have observed the
star-like phenomenon for more than 4 years, and the intensity depends on
the laser's power. Measuring the laser power of the dark bubble shows
the entrapment of electromagnetic energy as it expands.

Magnetizing laser-driven inertial fusion implosions
June 10, 2022
Nuclear
fusion is a widely studied process through which atomic nuclei of a low
atomic number fuse together to form a heavier nucleus, while releasing a
large amount of energy. Nuclear fusion reactions can be produced using a
method known as inertial confinement fusion, which entails the use of
powerful lasers to implode a fuel capsule and produce plasma.

New class of "non-Joulian magnets" have potential to revolutionize electronics
May 21, 2015
Magnets are at the heart of much of our technology, and their properties
are exploited in a myriad ways across a vast range of devices, from
simple relays to enormously complex particle accelerators. A new class
of magnets discovered by scientists at the University of
Maryland (UMD) and Temple University may lead to other types of magnets
that expand in different ways, with multiple, cellular magnetic fields,
and possibly give rise to a host of new devices. The team also believes
that these new magnets could replace expensive, rare-earth magnets with
ones made of abundant metal alloys.

Giant enhancement of magnetic effect will benefit spintronics
December 21, 2015
Researchers have demonstrated that coating a cobalt film in graphene doubles the film's perpendicular magnetic anisotropy (PMA), so that it reaches a value 20 times higher than that of traditional metallic cobalt/platinum multilayers that are being researched for this property. In a material with a high PMA, the magnetization is oriented perpendicular to the interface of the material's layers. High-PMA materials are being researched for their applications in next-generation spintronic devices, such as high-density memories and heat-tolerant logic gates.

Blue Light and Sunshine May be the Next Gen Weapons Against Antibiotic-Resistant Infections
March 14, 2013
http://articles.mercola.com/sites/articles/archive/2013/03/14/blue-light-therapy.aspx
Skin and soft tissue infections are among the most common bacterial infections encountered in clinical practice.
Such infections can be caused by a number of bacteria that gain entrance into your body via cuts, scrapes, bites or open wounds. Even bacteria that normally live on your skin can cause an infection when introduced into your body this way.
Skin and soft tissue infections account for more than 14 million hospital visits each year, costing the health care system an estimated $24 billion.
Unfortunately, many infections are becoming increasingly difficult to treat. Antibiotic overuse has led to the emergence of antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus, also known as MRSA.
Finding effective countermeasures to this growing public health threat has turned out few options, but the remedy may be as simple as colored light.
According to a new proof-of-principle study,1 blue light can selectively eliminate infections caused by Pseudomonas aeruginosa. According to lead researcher Michael R. Hamblin of the Massachusetts General Hospital:
"Microbes replicate very rapidly, and a mutation that helps a microbe survive in the presence of an antibiotic drug will quickly predominate throughout the microbial population. Recently, a dangerous new enzyme, NDM-1, that makes some bacteria resistant to almost all antibiotics available has been found in the United States. Many physicians are concerned that several infections soon may be untreatable.Blue light is a potential non-toxic, non-antibiotic approach for treating skin and soft tissue infections, especially those caused by antibiotic resistant pathogens."
Could Blue Light Replace Antibiotics?
In the study, lab animals were infected with P. aeruginosa. Incredibly, ALL of the animals treated with blue light survived, while 82 percent of the controls died. Could this possibly be the beginning of a whole new treatment paradigm for infections? Clearly, we’re nearing the end of the road of the antibiotic era, as antibiotic-resistance spreads.
Blue light therapy has also been shown to be effective against MRSA and other resistant bugs, offering new hope for effective treatments.
In a previous study published in 2009,3 over 90 percent of community acquired and hospital acquired strains of MRSA were successfully eradicated within mere minutes of exposure to blue light. According to the authors:

In plasmonics, 'optical losses' could bring practical gain
January 26, 2016
What
researchers had thought of as a barrier to developing advanced
technologies based on the emerging field of plasmonics is now seen as a
potential pathway to practical applications in areas from cancer therapy
to nanomanufacturing.
Plasmonic materials contain
features, patterns or elements that enable unprecedented control of
light by harnessing clouds of electrons called surface plasmons. It
could allow the miniaturization of optical technologies, bringing
advances such as nano-resolution imaging and computer chips that process
and transmit data using light instead of electrons, representing a
potential leap in performance.
However, the development
of advanced optical technologies using plasmonics has been hampered
because components under development cause too much light to be lost and
converted into heat. But now researchers are finding that this
"loss-induced plasmonic heating" could be key to development of various
advanced technologies, said Vladimir M. Shalaev, co-director of the new
Purdue Quantum Center, scientific director of nanophotonics at the Birck
Nanotechnology Center in the university's Discovery Park and a
distinguished professor of electrical and computer engineering.

Laser therapy works in a number of ways to heal injuries and manage pain. Among them:
- It increases the release of endorphins (natural painkillers).
- Laser therapy decreases inflammation, which helps return tissue to a normal state.
- It restores metabolic function.

History of Cold Laser Therapy
http://www.spine-health.com/treatment/pain-management/history-cold-laser-therapy
Cold Laser Therapy has been used in clinical practice all around the
world for over four decades. In 1916, Albert Einstein conceived the
theory of Light Amplification through Stimulated Emission of Radiation
or LASER. In 1967, Professor Andre Mester began using low power lasers
in medicine. Dr. Mester is recognized by many as the grandfather of
laser therapy.
The first experimental FDA clearance of Class 3B Lasers occurred in February of 2002, after a successful study for carpal tunnel syndrome on workers at General Motors. The laser that was used had a power of 90mw at 830nm.
Certain low level laser devices are also FDA approved for relief of the following conditions3,4:
- Muscle and joint pain
- Stiffness associated with arthritis
- Pain associated with muscle spasms
- Hand pain and wrist pain associated with Carpal Tunnel Syndrome
- Neck pain
- Lower back pain

Laser vaccine adjuvants
- Received: 14 Feb 2014
- Accepted: 9 Apr 2014
- Published online: 29 Apr 2014
Immunologic adjuvants are essential for current vaccines to maximize
their efficacy. Unfortunately, few have been found to be sufficiently
effective and safe for regulatory authorities to permit their use in
vaccines for humans and none have been approved for use with intradermal
vaccines. The development of new adjuvants with the potential to be
both efficacious and safe constitutes a significant need in modern
vaccine practice. The use of non-damaging laser light represents a
markedly different approach to enhancing immune responses to a vaccine
antigen, particularly with intradermal vaccination. This approach, which
was initially explored in Russia and further developed in the US,
appears to significantly improve responses to both prophylactic and
therapeutic vaccines administered to the laser-exposed tissue,
particularly the skin. Although different types of lasers have been used
for this purpose and the precise molecular mechanism(s) of action
remain unknown, several approaches appear to modulate dendritic cell
trafficking and/or activation at the irradiation site via the release of
specific signaling molecules from epithelial cells. The most recent
study, performed by the authors of this review, utilized a continuous
wave near-infrared laser that may open the path for the development of a
safe, effective, low-cost, simple-to-use laser vaccine adjuvant that
could be used in lieu of conventional adjuvants, particularly with
intradermal vaccines. In this review, we summarize the initial Russian
studies that have given rise to this approach and comment upon recent
advances in the use of non-tissue damaging lasers as novel physical
adjuvants for vaccines.

Discover the Benefits of K-Laser Class 4 Laser Therapy Treatments
July 28, 2013
What You Need to Know About Lasers
Lasers are classified according to their power output:
- Class 3a—maximum of 5 milliwatts of power (standard laser pointer)
- Class 3b—maximum of 500 milliwatts/0.5 watts
- Class 4—anything over 500 milliwatts/0.5 watts
The most significant issue with the clinical use of lasers is the depth of penetration. Some practitioners make the mistake of using low-power Class 3 lasers, which basically amounts to a standard laser pointer.
Most class 3a lasers only use a red wavelength – 635 nanometers in the visible red. When you look at the depth of penetration with laser, red laser light only penetrates about one to two millimeters (far less than 1/8 inch) into the human body.
Granted, red laser is highly useful for treating superficial wounds, cuts, abrasions, and perhaps even for the treatment of vitiligo, but they will not penetrate far enough for deep seated pain reduction. However, infrared lasers (around 800 nanometers) penetrate far deeper and able to go several centimeters, into your body which will reach most tissue injuries.
Power is also another crucial factor when it comes to laser therapy. Power is measured in watts, and you can think of it as the brightness of the light. A higher-powered laser is a brighter light, and it can produce more energy per unit of time. When it comes to doing laser therapy treatment, a higher-powered laser (Class 4) provides two benefits:
- A therapeutic dose of laser light can be applied to a much larger volume of tissue
- By shining that brighter light at the surface, photons of light are able to penetrate deeper into the tissues, which allows you to treat deep-seated pain conditions

Paintballs to deflect killer-asteroids
Mar 07, 2013
Having reviewed these traditional asteroid deflection techniques, Sung
Wook Paek, a graduate from the Massachusetts Institute of Technology,
suggests an unusual alternative: Mr Paek proposes using paintballs to
pull an asteroid off course.
The argument behind Mr Paek's idea is reasonably simple; after measuring the velocity and rotation of an incoming asteroid,
two unmanned spacecraft would approach the celestial body close enough
to be able to shoot large clouds of white paintballs at it! Two probes
would be needed because, as the asteroid rotates, a shot from only one
spacecraft would not cover the entire asteroid with white paint and so
the first probe strikes one side of the asteroid, the second probe
covers the other.
The white paint would reflect light and other electromagnetic radiation
from the asteroid's surface, and, over time, the cumulative effect of
billions of photons would result in the asteroid changing course. The
white paint would effectively act as a 'solar sail', increasing the
balance of solar radiation absorbed and emitted by the asteroid, gently
easing it away from its original destination.
Another deflection technique, also based on light reflectivity or laser
sublimation was proposed by a team of American researchers who suggested
launching a swarm of 'mirror bees' towards the potential killer.
Tiny probes, equipped with mirrors, would position themselves in such a
way as to reflect a concentration of sunlight on one specific point of
the asteroid. This 'beam of light' would then generate enough heat for
it to start to vaporise, creating propulsive gas jets. In essence,
vapour emitted from the asteroid would push it off-course.
Alternatively, the asteroid might 'simply' be wrapped in reflective
'foil'.

Laser Bees
What do we do if an asteroid is found to be on a collision course with Earth? At
this point, the answer is not clear, so The Planetary Society has
partnered with researchers to discover ways to protect Earth when we
one-day find a dangerous space rock.
We've been working with a team at the University of Strathclyde and
the University of Glasgow in Scotland to study a new technique which
uses concentrated light to gently move an asteroid -- a project we
called "Mirror Bees" -- using mirrors on several
spacecraft swarming around an asteroid to focus sunlight onto a spot on
the asteroid. As part of the initial Mirror Bees project, researchers
found that lasers are more effective than mirrors and can be used from
greater distances. So, now the project is called "Laser Bees."

Physicist unveils plan for entangling massive objects
August 5, 2015
Schnabel's plan is to
place two of the mirrors in a Michelson-type interferometer in such a
way as to have both sides of both mirrors hit by light that is sent in.
The mirrors would also be placed in the interferometer in a way that
would allow them to oscillate when struck by the light. This would allow
for momentum to be transferred between the mirrors and the light. The
mirror oscillations would then have an impact on the phase of the
reflected light, causing the momentum and the light to become entangled.
At that point, the entanglement could be "swapped" to the mirrors,
causing them to be entangled, by measuring the light beams as they exit.

DE-STAR
is designed to vaporize or divert asteroids that threaten Earth. This
isn't science fiction—I build things that have to work in practice.
DE-STAR stands for Directed Energy Solar Targeting of Asteroids and
exploRation. It looks like an open matchbook with lasers on one flap and
a photovoltaic panel for power from sunlight on the other. By
synchronizing the laser beams, we can create a phased array, which
produces a steerable 70-gigawatt beam. An onboard system receives orders
on what to target. Our laser beam would then produce a spot about 100
feet in diameter on an asteroid that's as far away from the satellite as
we are from the sun. The laser would raise an asteroid's surface
temperature to thousands of degrees Celsius—hot enough that all known
substances evaporate. In less than an hour, DE-STAR could have
completely vaporized the asteroid that broke up over Russia this winter,
if we had seen it coming. Plus, as the material evaporates, it creates a
thrust in the opposite direction, comparable to the space shuttle's
rocket booster. That means you could divert the asteroid by changing its
orbit with a shorter laser blast.
DE-STAR could also power things on Earth or in space. You could send
the electrical power it produces—not via laser beam but via microwaves.
Or you could use the laser to directly propel spacecraft. But here's the
thing: For full-blown asteroid vaporization, each flap of the matchbook
would have to be six miles long. We've never built a structure this
size in space, but if there were the worldwide will, I could see
building this within 30 to 50 years. But since it's completely modular,
we propose starting smaller. We could begin with a version that's three
feet per side right now. With that, you could cook your dinner from 600
miles away.

For
five years, Felix du Pont worked for the family owned DuPont and for a
short time became involved in the investment business. With a lifelong
interest in aviation, he partnered with brother Richard to found All
American Aviation Company which became Allegheny Airlines and eventually
US Airways. He later was a vice president of the Piasecki Helicopter
Corp. of which he and Laurence Rockefeller were early investors on its
founding in 1946.
Piasecki
Helicopter Corporation was a designer and manufacturer of helicopters
located in Philadelphia, Pennsylvania and nearby Morton, Pennsylvania in
the late 1940s and the 1950s. Its founder, Frank Piasecki, was ousted
from the company in 1956 and started a new company, Piasecki Aircraft. Piasecki Helicopter was renamed Vertol Corporation in early 1956.
Vertol was acquired by Boeing in 1960 and renamed Boeing Vertol.

Electric Laser Race Heats Up
2012
http://sites.psu.edu/thebigbangtheory/2012/10/29/the-holographic-excitation/
Not wanting to be left out of the race to field compact battlefield lasers, Boeing announced yesterday
that it’s tested its own solid-state laser technology. "In each laser
firing at Boeing’s facility in West Hills, Calif., the high-energy laser
achieved power levels of over 25 kilowatts for multi-second durations,
with a measured beam quality suitable for a tactical weapon system,"
says Boeing.
What’s interesting about this announcement is that Boeing is not part of the Defense Department’s Joint High-Powered Solid State Laser,
a program that has funded Northrop Grumman and Textron to build a
deployable laser weapon. Boeing at one point teamed with the Livermore
lab on a solid-state work, but that laser, which was powerful but large,
was not selected by the program for funding. Similarly, Raytheon also
has a solid state laser that was passed over for funding. Both Livermore
and Raytheon have continued their solid-state laser work on their own
dime, however. Boeing, until this point, did not appear to be that
active on solid-state lasers, and it appears this new effort is
self-funded.

Lockheed Martin begins manufacturing vehicle-mounted laser weapon
October 8, 2015
Lockheed Martin announced this week that production of a new laser
weapon system has begun at the company's Bothell, Washington facility.
The high-powered laser weapon modules will be used as the heart of a
60-kilowatt system designed to be fitted to a US Army vehicle.
The laser can be operated by a single person and is
made up of multiple fiber laser modules, which not only allows for
greater flexibility, but also lessens the chance of the weapon being
knocked out by a minor malfunction, so frequent repairs aren't required.
Lockheed Martin also says that the modular design means that the laser
power can be varied across an extremely wide range to suit specific
mission needs. Using off-the-shelf commercial fiber laser components to
keep down costs, the modules can be linked together to produce lasers of
up to 120 kW.

A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid such as in dye lasers or a gas as in gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers (see Laser diode).
Solid-state lasers are being developed as optional weapons for the F-35 Lightning II, and are reaching near-operational status, as well as the introduction of Northrop Grumman's FIRESTRIKE laser weapon system. In April 2011 the United States Navy tested a high energy solid state laser. The exact range is classified, but they said it fired "miles not yards".

Shooting lightning out of the sky
New methods to make longer streams of plasma with greater longevity could lead to laser-powered lightning rods
September 24, 2015
A team of researchers has demonstrated new techniques that bring lasers
as lighting rods closer to reality. When a powerful laser beam shoots
through the air, it ionizes the molecules, leaving a thin trail of hot,
ionized particles in its wake. Because this stream of plasma conducts
electricity, it could be used to channel away a potentially damaging
lightning bolt. The researchers found ways to make the length of such a
plasma channel reach more than 10 times longer -- a necessary advance
for using the channel to redirect a lightning strike.

electromagnetic microwave ionospheric heater in Gakona, Alaska, for
military communication and weapon “defense” purposes. They also take
part in biological warfare “testing” over land, water, and city, whereby
defense contractor jets, such as those crafted especially for war or

BAE and Raytheon, hardware and software hosted by none other than
Microsoft, so that their defense contractor industry market could remain

World's most powerful laser to tear apart the vacuum of space
_____________
How we recreated the early universe in the laboratory
May 12, 2015
- Instead of focusing our attention on
immense particle accelerators, we turned to the ultra-intense lasers
available at the Central Laser Facility at the Rutherford Appleton
Laboratory in Oxfordshire, UK. We used an ultra-high vacuum chamber with
an air pressure corresponding to a hundredth of a millionth of our
atmosphere to shoot an ultra-short and intense laser pulse (hundred
billions of billions more intense that sunlight on the Earth surface)
onto a nitrogen gas. This stripped off the gas' electrons and
accelerated them to a speed extremely close to that of light.
The
beam then collided with a block of lead, which slowed them down again.
As they slowed down they emitted particles of light, photons, which
created pairs of electrons and their anti-particle, the positron, when
they collided with nuclei of the lead sample. A chain-reaction of this
process gave rise to the plasma.
However, this
experimental achievement was not without effort. The laser beam had to
be guided and controlled with micrometer precision, and the detectors
had to be finely calibrated and shielded – resulting in frequent long
nights in the laboratory.
But it was well worth it as
the development means an exciting branch of physics is opening up. Apart
from investigating the important matter-antimatter asymmetry, by
looking at how these plasmas interact with ultra powerful laser beams,
we can also study how this plasma propagates in vacuum and in a
low-density medium. This would be effectively recreating conditions
similar to the generation of gamma-ray bursts, some of the most luminous
events ever recorded in our universe.

Holometer rules out first theory of space-time correlations
December 4, 2015
http://phys.org/news/2015-12-holometer-theory-space-time.html
The Holometer is a deceptively simple device. It uses a pair of laser interferometers placed close to one another, each sending a one-kilowatt beam of light through a beam splitter and down two perpendicular arms, 40 meters each. The light is then reflected back into the beam splitter where the two beams recombine. If no motion has occurred, then the recombined beam will be the same as the original beam. But if fluctuations in brightness are observed, researchers will then analyze these fluctuations to see if the splitter is moving in a certain way, being carried along on a jitter of space itself.
According to Fermilab's Aaron Chou, project manager of the Holometer experiment, the collaboration looked to the work done to design other, similar instruments, such as the one used in the Laser Interferometer Gravitational-Wave Observatory (LIGO) experiment. Chou said that once the Holometer team realized that this technology could be used to study the quantum fluctuation they were after, the work of other collaborations using laser interferometers (including LIGO) was invaluable.
"No one has ever applied this technology in this way before," Chou said. "A small team, mostly students, built an instrument nearly as sensitive as LIGO's to look for something completely different."
The challenge for researchers using the Holometer is to eliminate all other sources of movement until they are left with a fluctuation they cannot explain. According to Fermilab's Chris Stoughton, scientist on the Holometer experiment, the process of taking data was one of constantly adjusting the machine to remove more noise.
"You would run the machine for a while, take data, and then try to get rid of all the fluctuation you could see before running it again," he said. "The origin of the phenomenon we're looking for is a billion billion times smaller than a proton, and the Holometer is extremely sensitive, so it picks up a lot of outside sources, such as wind and traffic."
If the Holometer were to see holographic noise that researchers could not eliminate, it might be detecting noise that is intrinsic to space-time, which may mean that information in our universe could actually be encoded in tiny packets in two dimensions.
The fact that the Holometer ruled out his theory to a high level of significance proves that it can probe time and space at previously unimagined scales, Hogan said. It also proves that if this quantum jitter exists, it is either much smaller than the Holometer can detect, or is moving in directions the current instrument is not configured to observe.
So what's next? Hogan said the Holometer team will continue to take and analyze data, and will publish more general and more sensitive studies of holographic noise. The collaboration already released a result related to the study of gravitational waves.
And Hogan is already putting forth a new model of holographic structure that would require similar instruments of the same sensitivity, but different configurations sensitive to the rotation of space. The Holometer, he said, will serve as a template for an entirely new field of experimental science.
"It's new technology, and the Holometer is just the first example of a new way of studying exotic correlations," Hogan said. "It is just the first glimpse through a newly invented microscope."

Nanoparticles found to violate second law of thermodynamics
April 3, 2014
It may be a little late for April Fool's, but some skepticism is nonetheless warranted when reading that researchers have shown nanoparticles to disobey a fundamental law of physics which dictates the flow of entropy and heat in, it was believed, any situation. Specifically, researchers from three universities theoretically proposed then demonstrated that a nanoparticle in a state of thermal non-equilibrium does not always behave as larger particles might under the same conditions, with implications for various fields of research.
The second law of thermodynamics is the one that makes perpetual motion machines impossible. It states that the entropy – the measure for the disorder of a system – of any isolated system cannot decrease spontaneously, with the system evolving towards the state of maximum entropy (favoring disorder). The team has shown that a nanoparticle trapped with laser light temporarily violates this law. This seeming violation of universal law is transient, something that the researchers first derived as a mathematical model of fluctuations expected at the nanoscale.

Scientists announce breakthrough in quest for fusion power
February 13, 2014
http://www.gizmag.com/fusion-breakthrough/30814/?li_source=LI&li_medium=default-widget
In a perfect example of beating swords into plowshares, a team of
scientists at the Lawrence Livermore National Laboratory's (LLNL)
National Ignition Facility (NIF) in California reached a milestone in
the quest for practical fusion power using a process designed for the
development and testing of nuclear weapons. The announcement in the
February 12 issue of Nature claims that the team used the
world’s most powerful laser barrage to produce a controlled fusion
reaction where more energy was extracted from the fuel than was put into
it.
If there is an ultimate engineering dream, then
nuclear fusion is about as close as close as one can get. By literally
harnessing the power of the stars, it holds the promise of what is, for
all practical purposes, unlimited clean energy. Since man-made fusion
was first demonstrated in 1951 with a boosted fission weapon, scientists and engineers have worked on some way to produce a practical fusion reactor instead of a hydrogen bomb.
The story of the fusion reactor is one of both great
progress, but also constant frustration. When work began, the first
reactor was predicted to be 25 years away. Since then and up until
today, it’s still 25 years away. That’s because although nuclear fusion
is relatively simple in theory, getting a controlled reaction started
outside of the heart of a star is extremely difficult. The trick is to
reach the “ignition” point, where the energy released by the reactor is
greater than what’s put into it and the reaction becomes
self-sustaining.
A fusion reactor works by simulating the conditions
inside the Sun. Put simply, hydrogen atoms fuse in the Sun because its
huge mass squashes the atoms together to form helium, releasing huge
amounts of energy as the strong nuclear force that keeps them apart is
overcome. A hydrogen bomb does the same thing, only with a fission bomb
creating the necessary conditions for a millionth of a second.

Apparent breakthrough in nuclear fusion silenced by shutdown
Scientists have come one step closer to harnessing the power of the sun. Researchers at the National Ignition Facility (NIF) have passed a milestone in achieving self-sustaining nuclear fusion -- but you won't hear about it from the researchers. The NIF team has been furloughed as a result of the U.S. government shutdown, which began on Oct. 1, and is not releasing updates to the press.
According to the BBC,
a research experiment conducted in late September succeeded in
releasing more energy through a fusion reaction than it absorbed by the
fuel going in. NIF is the first research facility in the world to
achieve this goal. A spokesperson for the NIF could not give CBSNews.com
a comment on the results of the experiment.
NIF's method for achieving fusion involves sending 192 laser beams
through a 1,500-meter journey that increases its energy output by a
factor of more than a quadrillion. The laser beams' energy grows from
one-billionth of a joule to 4 million joules in 5 millionths of a
second.
A breakthrough in nuclear fusion is widely considered the holy grail of achieving an unlimited clean energy source.
Scientists
believe that fusion can fuel our future without threat of nuclear
proliferation or environmental damage because the process of creating
fusion requires very few resources. One of the biggest challenges in
producing energy derived from fusion has been to pass the break-even
point -- a goal that has eluded scientists for nearly 50 years.
Nuclear
fusion is not to be confused with nuclear fission. Instead of splitting
an atom's nucleus, like in fission, nuclear fusion is the process of
bringing together two atomic nuclei to form a new nucleus.
While
the NIF has passed the break-even point, it is just shy of reaching
"ignition" -- when nuclear fusion produces as much energy as is supplied
to the lasers.

Weather could be controlled using lasers
Scientists are attempting to control the weather by using lasers to create clouds, induce rain and even trigger lightning.
Experts from around the world are to gather at the World Meteorological Organisation next month to discuss how powerful laser pulses can be used to generate changes in the atmosphere that influence the weather.
There is a long history of attempts by scientists to control the weather,
including using techniques such as cloud seeding.
This involves spraying small particles and chemicals into the air to induce
water vapour to condense into clouds.
In the 1960s the United States experimented with using silver iodide in an
attempt to weaken hurricanes before they made landfall.
The USSR was also claimed to have flown
cloud seeding missions in an attempt to create rain clouds to protect
Moscow from radioactive fallout from the Chernobyl nuclear disaster.
More recently the Russian Air force has also been reported to have used bags
of cement to seed clouds.
Before the 2008 Olympic Games in Beijing, the Chinese authorities used
aircraft and rockets to release chemicals into the atmosphere.
Other countries have been reported to be experimenting with cloud seeding to
prevent flooding or smog.
However, Professor Wolf, Dr Kasparian and their colleagues believe that lasers
could provide an easier and more controllable method of changing the
weather.
They began studying lasers for their use as a way of monitoring changes in the
air and detecting aerosols high in the atmosphere.

Laser-induced condensation shows promise for cloud seeding
2012
Over the past decade,
commercially-available lasers have increased in power by two orders
of magnitude, reaching the petawatt level, with exawatts firmly
within sight. The 2011 experiment used a 100 terawatt laser, and a
"mobile" (actually the size of a shipping container) laser of five
terawatts.
Further understanding of how lasers spur condensation will also
help. The process, known as photodissociation,
involves the laser's photons breaking down atmospheric compounds to
produce ozone and nitrogen molecules. Those in turn form nitric
acid particles, which bind water molecules together into
droplets.

Second Conference on Laser, Weather and Climate (LWC 2013)
http://www.laserweatherandclimate.com/
Welcome
As
highlighted by the success of the first Conference on Laser-based
Weather Control in 2011, ultra-short lasers launched into the atmosphere
have emerged as a promising prospective tool for weather modulation and
climate studies. Such prospects include lightning control and
laser-assisted condensation, as well as the striking similarities
between the non-linear optical propagation and natural phenomena like
rogue waves or climate bifurcations.
Filaments
generated by ultra-short laser pulses launched into the atmosphere have
emerged as an unexpected prospective tool for weather modulation. In
particular, lightning control and laser-assisted water condensation
recently appeared as spectacular prospects in this direction.
Although
these new perspectives triggered an increasing interest and activity in
many groups worldwide, the highly interdisciplinary nature of the
subject limited its development, due to the need for enhanced contacts
between laser and atmospheric physicists, chemists, electrical
engineers, and meteorologists.

Physicist finds mysterious anti-electron clouds inside thunderstorm
May 13, 2015
In August 2009, Dwyer and colleagues were aboard a National Center for
Atmospheric Research Gulfstream V when it inadvertently flew into the
extremely violent thunderstorm—and, it turned out, through a large cloud
of positrons, the antimatter opposite of electrons, that should not
have been there.
To encounter a cloud of positrons without other
associated physical phenomena such as energetic gamma-ray emissions was
completely unexpected, thoroughly perplexing and contrary to currently
understood physics.
"The fact that, apparently out of nowhere,
the number of positrons around us suddenly increased by more than a
factor of 10 and formed a cloud around the aircraft is very hard to
understand. We really have no good explanation for it," says Dwyer, a
lightning expert and the UNH Peter T. Paul Chair in Space Sciences at
the Institute for the Study of Earth, Oceans, and Space.
It is
known that thunderstorms can sometimes make flashes of energetic gamma
rays, which may produce pairs of electrons and positrons when they
interact with air. But the appearance of positrons should then coincide
with a large increase in the number of gamma rays.
"We should
have seen bright gamma-ray emissions along with the positrons," Dwyer
says. "But in our observations, we first saw a positron cloud, then
another positron cloud about seven kilometers away and then we saw a
bright gamma-ray glow afterwards. So it's all not making a whole lot of
sense."

Researchers show presence of charge-density waves in superconductive material
December 10, 2015
Ultrafast laser techniques helped MIT physics graduate student Fahad Mahmood and colleagues establish that electrons form charge-density waves in the thin-film superconductive material LSCO cuprate.
"The question is how does this fluctuating charge-density wave compete
or not interfere with superconductivity, and what we found is that it
actually competes with superconductivity," Mahmood explains. "Electrons
for a very short amount of time are in this charge-density wave state,
and in another time scale, if you take another snapshot, they'll be in
the superconductivity state."
Charge-density waves occur when
electron density in a conductor is distributed in a sinusoidal pattern,
like ripples on water, instead of the common uniform density.
"It's
a fluctuating order that lasts for a very short amount of time and
equilibrium probes won't be able to detect it," he says. Using ultrafast
spectroscopy, Mahmood and co-authors of a 2013 Nature Materials paper
were able to show that for extremely short periods of time—up to about 2
picoseconds—electrons clustered in a density wave that could be
measured by its amplitude and phase.

Atmospheric Vortex Engine creates tornadoes to generate electricity

Tornadoes generally evoke the destructive force of nature at its most awesome. However, what if all that power could be harnessed to produce cheaper and more efficient electricity? This is just what Canadian engineer Louis Michaud proposes to achieve, with an invention dubbed the “Atmospheric Vortex Engine” (or AVE).
AVE works by introducing warm air into a circular station, whereupon the difference in temperature between this heated air and the atmosphere above creates a vortex – or controlled tornado, which in turn drives multiple wind turbines in order to create electricity. The vortex could be shut down by simply turning off the source of warm air.

Researchers at Pacific Northwest National Laboratory found that volcanic ash is not as efficient as common dust in birthing clouds' ice particles. Using a novel laboratory testing chamber they formed cloud ice, a process called ice nucleation, around particles of dust and volcanic ash. Their results revealed the importance of optimal particle structure to efficiently attract super cold water vapor to nucleate ice.

Enhancement of electron energy during vacuum laser acceleration in an inhomogeneous magnetic field
In this paper, the effect of a stationary inhomogeneous magnetic field on the electron acceleration by a high intensity Gaussian laser pulse is investigated. A focused TEM (0,0) laser mode with linear polarization in the transverse x-direction that propagates along the z-axis is considered. The magnetic field is assumed to be stationary in time, but varies longitudinally in space. A linear spatial profile for the magnetic field is adopted. In other words, the axial magnetic field increases linearly in the z-direction up to an optimum point

Jellyfish proteins used to create polariton laser
August 22, 2016
A combined team of researchers from Scotland and Germany has developed a way to create a polariton laser by using jellyfish proteins cultivated in E. coli cells. In their paper published in the journal Science Advances, the team describes their technique and possible uses for the result.
As most people know, at a basic level, conventional lasers work by bouncing light around inside of a cavity and then emitting identical photons as a beam. There is another type of laser that is less well known, the polariton laser—it works by tossing photons back and forth between excited molecules. But the reason it has not made its way into commercial use is because it must be cooled to an extremely low temperature to work properly. In this new approach, the researchers report the development of such a laser that works at room temperatures.

Induction plasma
Induction
plasma, also called inductively coupled plasma, is a type of high
temperature plasma generated by electromagnetic induction, usually
coupled with argon gas. The magnetic field induces an electric current
within the gas which creates the plasma. The plasma can reach
temperatures up to 10,000 Kelvin. Inductive plasma technology is used in
fields such as powder spheroidization and nano-material synthesis. The
technology is applied via an Induction plasma torch, which consists of
three basic elements: the induction coil, a confinement chamber, and a
torch head, or gas distributor. The main benefit of this technology is
the elimination of electrodes, which can deteriorate and introduce
contamination.

______________
Nonthermal plasma
https://en.wikipedia.org/wiki/Nonthermal_plasma
A
nonthermal plasma, cold plasma or non-equilibrium plasma is a plasma
which is not in thermodynamic equilibrium, because the electron
temperature is much hotter than the temperature of heavy species (ions
and neutrals). As only electrons are thermalized, their
Maxwell-Boltzmann velocity distribution is very different from the ion
velocity distribution.[1] When one of the velocities of a species does
not follow a Maxwell-Boltzmann distribution, the plasma is said to be
non-Maxwellian.
A kind of common nonthermal plasma is the
mercury-vapor gas within a fluorescent lamp, where the "electron gas"
reaches a temperature of 20,000 K (19,700 °C; 35,500 °F) while the rest
of the gas, ions and neutral atoms, stays barely above room temperature,
so the bulb can even be touched with hands while operating.
Food industry
In
the context of food processing, a nonthermal plasma (NTP) or cold
plasma is specifically an antimicrobial treatment being investigated for
application to fruits, vegetables and meat products with fragile
surfaces. These foods are either not adequately sanitized or are
otherwise unsuitable for treatment with chemicals, heat or other
conventional food processing tools. While the applications of nonthermal
plasma were initially focused on microbiological disinfection, newer
applications such as enzyme inactivation, biomolecule oxidation, protein
modification, prodrug activation, and pesticide dissipation are being
actively researched. Nonthermal plasma also sees increasing use in the
sterilization of teeth[8][9] and hands, in hand dryers as well as in
self-decontaminating filters.
The term cold plasma has been
recently used as a convenient descriptor to distinguish the
one-atmosphere, near room temperature plasma discharges from other
plasmas, operating at hundreds or thousands of degrees above ambient
(see Plasma (physics) § Temperature. Within the context of food
processing the term "cold" can potentially engender misleading images of
refrigeration requirements as a part of the plasma treatment. However,
in practice this confusion has not been an issue. "Cold plasmas" may
also loosely refer to weakly ionized gases (degree of ionization <
0.01%).
Nomenclature
The nomenclature for nonthermal plasma found
in the scientific literature is varied. In some cases, the plasma is
referred to by the specific technology used to generate it ("gliding
arc", "plasma pencil", "plasma needle", "plasma jet", "dielectric
barrier discharge", "piezoelectric direct discharge plasma", etc.),
while other names are more generally descriptive, based on the
characteristics of the plasma generated ("one atmosphere uniform glow
discharge plasma", "atmospheric plasma", "ambient pressure nonthermal
discharges", "non-equilibrium atmospheric pressure plasmas", etc.). The
two features which distinguish NTP from other mature, industrially
applied plasma technologies, is that they are 1) nonthermal and 2)
operate at or near atmospheric pressure.

Pyrolysis of Polyolefins Using Rotating Arc Plasma Technology for Production of Acetylene
2017
Abstract
Polyolefin, as one of the most widely used macromolecule materials, has
been one of the most serious threats to the environment. Current
treatment methods of waste polyolefin including landfill, incineration,
and thermal degradation have suffered from severe problems such as
secondary pollution and the generation of other toxic substances. In
this article, we report for the first time a high-efficiency method to
produce high-value C2H2 from polyolefins using a
rotating direct current arc plasma reactor, using polyethylene and
polypropylene as feedstocks. The essence of this method is that a
reductive atmosphere of pyrolysis enables a thermodynamic preference to C2H2
over other carbon-containing gas and the rotating direct current arc
plasma reactor allows for a uniform distribution of high temperature to
ensure high conversion of polymers. Thermodynamic simulation of product
composition was performed, and the effect of plasma input power,
polyolefin feed rate, and working gas flow rate on the pyrolysis results
was experimentally investigated. It was found that, with proper
parameter control, approximately complete conversion of carbon in
polyolefin could be obtained, with a C2H2 selectivity higher than 80% and a C2H2
yield higher than 70%. These results not only create new opportunities
for the reuse of polymer waste, but are also instructive for the green
production of C2H2.

A Review of Magnetic Shielding Technology for Space Radiation
March 1, 2023
Simple Summary
Successful
human exploration beyond Earth orbit relies on solving the issue of
high radiation doses received in space. Many passive and active
radiation mitigation strategies have been proposed over the past several
decades, but the problem remains to be solved. A promising concept
exists to use superconducting magnets to effectively recreate the
benefit of Earth’s magnetic field and deflect incoming space radiation
before it ever reaches the spacecraft. This type of radiation shielding
technology has been studied since the dawn of human space exploration in
the 1960s but has experienced highs and lows in its development since.
This paper summarizes the findings of research on this topic and
suggests that a linkage exists between studies of cutting-edge space
technologies such as magnetic shielding and the overall budget for human
spaceflight endeavors.

New methods to make longer streams of plasma with greater longevity could lead to laser-powered lightning rods
September 24, 2015
(
A picture of a femtosecond laser. The laser beam itself is invisible
(800nm), but due to the formation of a plasma channel, the beam emits
(visible) white light. )
Benjamin
Franklin invented the lightning rod 250 years ago to protect people and
buildings from lightning strikes. Someday, those metal poles may be
replaced with lasers.
A team of researchers
from The Hebrew University of Jerusalem, Israel, have demonstrated new
techniques that bring lasers as lighting rods closer to reality.
When
a powerful laser beam shoots through the air, it ionizes the molecules,
leaving a thin trail of hot, ionized particles in its wake. Because
this stream of plasma conducts electricity, it could be used to channel
away a potentially damaging lightning bolt.
The
researchers found ways to make the length of such a plasma channel reach
more than 10 times longer—a necessary advance for using the channel to
redirect a lightning strike.

Researchers build real-time tunable plasmon laser
4/24/2015
Traditionally,
light can only ever be focused down to a point half the size of its
frequency—aka the diffraction limit. Scientists have found a way around
that limit, however, by building what are known as plasmon lasers, which
are lasers that couple their beam with plasmons (oscillating surface
electrons) on the surface of metals—gold for example, arranged in an
array. But that approach has had its limitations as well, because it has
had to rely on a solid bit of material called the gain—such lasers
could not be tuned very easily, and not in real-time at all. In this new
effort, the researchers report that they have found a way to use a
liquid material as the gain, and because of that, are able to tune their
laser in real time.

Rotation
is key to the performance of salad spinners, toy tops, and centrifuges,

of mankind's energy supply. In papers published in Physics of Plasmas in

can use to manipulate the intrinsic - or self-generated - rotation of
hot, charged plasma gas within fusion facilities called tokamaks.
Such
a method could prove important for future facilities like ITER, the
huge international tokamak under construction in France that will
demonstrate the feasibility of fusion as a source of energy for
generating electricity. ITER's massive size will make it difficult for
the facility to provide sufficient rotation through external means.

Kilotesla Magnetic Field due to a Capacitor-Coil Target Driven by High Power Laser

Laboratory generation of strong magnetic fields opens new frontiers in
plasma and beam physics, astro- and solar-physics, materials science,
and atomic and molecular physics. Although kilotesla magnetic fields
have already been produced by magnetic flux compression using an
imploding metal tube or plasma shell, accessibility at multiple points
and better controlled shapes of the field are desirable. Here we have
generated kilotesla magnetic fields using a capacitor-coil target, in
which two nickel disks are connected by a U-turn coil. A magnetic flux
density of 1.5 kT was measured using the Faraday effect 650 μm away from the coil, when the capacitor was driven by two beams from the GEKKO-XII laser (at 1 kJ (total), 1.3 ns, 0.53 or 1 μm, and 5 × 1016 W/cm2).

Tesla experimented with a number of different configurations consisting of two, or sometimes three, coupled resonant electric circuits.
Tesla used these coils to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires. Tesla coil circuits were used commercially in sparkgap radio transmitters for wireless telegraphy until the 1920s, and in medical equipment such as electrotherapy and violet ray

Scalar Waves: Nicola Tesla's Forgotten Discovery Of A Source Of Clean, Cost Free Energy
Scalar wavelengths are finer than gamma rays or X rays and only one hundred millionth of a square centimeter in width. They belong to the subtle gravitational field and are also known as gravitic waves. Uniquely, they flow in multiple directions at right angles off electromagnetic waves, as an untapped energy source called 'potentials'. Potentials are particles which are unorganized in hyperspace - pure etheric energy not manifest in the physical world. In comparison, electromagnetic waves (measured by so many hertz or pulses per second, with which we are familiar with as radio other waves in the electro-magnetic spectrum) exist normally in the physical world, but can only be measured up to levels determined by the sensitivity of the equipment being used as to how many cycles per second they operate.

Getting a charge from changes in humidity

New type of generator built with bacterial spores could one day provide a steady source of green electricity
BOSTON — A new type of electrical generator uses bacterial spores to harness the untapped power of evaporating water, according to research conducted at the Wyss Institute of Biologically Inspired Engineering at Harvard University. Its developers foresee electrical generators driven by changes in humidity from sun-warmed ponds and harbors.
The prototype generators work by harnessing the movement of a sheet of rubber coated on one side with spores. The sheet bends when it dries out, much as a pine cone opens as it dries or a freshly fallen leaf curls, and then straightens when humidity rises. Such bending back and forth means that spore-coated sheets or tiny planks can act as actuators that drive movement, and that movement can be harvested to generate electricity.

A new clean nuclear fusion reactor has been designed

A
researcher at the Universidad politécnica de Madrid (UPM, Spain) has
patented a nuclear fusion reactor by inertial confinement that, apart
from be used to generate electric power in plants, can be applied to
propel ships.
This invention is the result of a work
carried out by the Professor José Luis González Díez from the Higher
Technical School of Naval Engineering of the UPM, who has contributed to
solve the problem of contamination risk associated with the generation
of nuclear fission power. It is a design of a fusion nuclear reactor by
laser ignition of 1000 MWe that uses as fuel hydrogen isotopes that can
be extracted from water allowing us a significant saving in fuel.
The
nuclear fission is generally considered as a dangerous energy due to
its contaminant risks of radioactive waste resulting from the
electricity generation process. The past events occurred in Japan after
the tsunami of 2011 increased the risk perception of this type of energy
generation what has provoked that research on alternative ways to
obtain energy have gained more importance than ever.
For
years, nuclear fusion was studied as an alternative to nuclear fission
because of its remarkable advantages for security and financial issues.
However, today, there is not working any fusion reactor to produce
continuous electrical energy of high voltage.

An electrostatic nuclear accelerator is one of the two main types of particle accelerators, where charged particles can be accelerated by subjection to a static high voltage potential. The static high voltage method is contrasted with the dynamic fields used in oscillating field particle accelerators. Owing to their simpler design, historically these accelerators were developed earlier. These machines are operated at lower energy than some larger oscillating field accelerators, and to the extent that the energy regime scales with the cost of these machines, in broad terms these machines are less expensive than higher energy machines, and as such they are much more common. Many universities world wide have electrostatic accelerators for research purposes.

TESLA project goes public

At a major event held at the DESY laboratory in March (see News May 2000), the international TESLA collaboration, together with the members of various study groups, released the TESLA Technical Design Report. This five-volume opus presented the final facts and figures concerning a grand plan for the future: the "TeV-Energy Superconducting Linear Accelerator", a 33 km electron-positron linear collider with an integrated X-ray laser laboratory.
To be built near the DESY laboratory in Hamburg, the facility would not only provide particle collision energies of 500 GeV - which could be increased to 800 GeV - but also include powerful X-ray lasers that would open up new research opportunities in a variety of fields, ranging from condensed matter physics through chemistry and material science to structural biology.
It is widely acknowledged among particle physicists that a linear accelerator colliding electrons and positrons is the ideal machine to complement CERN's Large Hadron Collider, which is due to start operation in 2006. As well as the TESLA collaboration, plans for similar next-generation linear electron-positron colliders are being worked on by other teams.
SLAC in the US and KEK in Japan are jointly developing two similar designs - known respectively as the Next Linear Collider and the Japan Linear Collider - which could be ready for construction at around the same time as TESLA. CERN is also working on a next-generation collider, CLIC. However, the TESLA proposal is the first to be fully costed and made public. It is also the only project to include an X-ray laser laboratory and thus to address a large interdisciplinary research community.

Meson f0(1710) could be so-called “glueball” particle made purely of nuclear force
Terms to describe the strange world of quantum physics have come to
be quite common in our lexicon. Who, for instance, hasn't at least heard
of a quark, or a gluon or even Schrodinger's cat? Now there's a new
name to remember: "Glueball." A long sought-after exotic particle, and
recently claimed to have been detected by researchers at TU Wien, the
glueball's strangest characteristic is that it is composed entirely of
gluons. In other words, it is a particle created from pure force.
First mooted as a particle in 1972 when physicists
Murray Gell-Mann and Harald Fritsch wondered about possible bound states
of recently-discovered gluons, scientists have sought the particle in
the intervening decades. Originally dubbed "gluonium," but now called
glueballs, these strange particles of pure force are exceptionally
unstable and can only be indirectly detected by monitoring their decay
as they disassemble into lesser particles.
More recently, physics Professor Anton
Rebhan and his PhD student Frederic Brünner from TU Wien have theorized
that a strong nuclear decay resonance, called f0(1710), observed in the
data from a number of particle accelerator experiments is strong
evidence for the elusive glueball particle...

Big Chill Sets in as RHIC Physics Heats Up
Run 14 promises highest collision rates enabling exploration of detailed properties of early-universe matter
UPTON, NY—If you think it's been cold outside this winter, that's nothing compared to the deep freeze setting in at the Relativistic Heavy Ion Collider
(RHIC), the early-universe-recreating "atom smasher" at the U.S.
Department of Energy's Brookhaven National Laboratory. Brookhaven's
accelerator physicists have begun pumping liquid helium into RHIC's
1,740 superconducting magnets to chill them to near absolute zero (-273
degrees Celsius—the coldest anything can get) in preparation for the
collider's next physics run.
Once that extreme subzero temperature is reached, enabling the
magnets to operate with zero energy loss, the physicists will begin
injecting beams of gold ions and steering them into head-on collisions
at nearly the speed of light. Those collisions create temperatures at
the opposite extreme of the temperature scale—4 trillion degrees
Celsius, or 250,000 times hotter than the center of the sun—to produce
RHIC's signature "perfect" liquid
quark-gluon plasma, a stand in for what the universe was like an

RHIC particle smashups find that shape matters
December 7, 2015
Peering into the seething soup of
primordial matter created in particle collisions at the Relativistic
Heavy Ion Collider (RHIC)-an "atom smasher" dedicated to nuclear physics
research at the U.S. Department of Energy's Brookhaven National
Laboratory-scientists have come to a new understanding of how particles
are produced in these collisions. This understanding represents a
paradigm shift consistent with the presence of a saturated state of
gluons, super-dense fields of the glue-like particles that bind the
building blocks of ordinary matter.

Physicists search for signs of supersymmetry
December 17, 2015
The
first results from direct searches for new physics were announced today
from CERN's energy-upgraded Large Hadron Collider (LHC). Among these
results was a search for signs of a new theory called supersymmetry in
which members of the University of Bristol particle physics group have
played a leading role.
The LHC is the
world's highest energy particle accelerator. After an almost two year
shutdown and several months' re-commissioning, the LHC delivered physics
data to its experiments from June to November this year at the
unprecedented energy of 13 TeV, almost double the collision energy of
its first run. The energy of the colliding protons is such that new
particles much heavier than the proton can be created including the
famous Higgs boson, and possibly even heavier and more exotic particles
hypothesised in new physics theories. One such theory is called
supersymmetry, which predicts an exotic partner for each currently known
particle type.

Four new elements confirmed
January 4, 2016
http://www.gizmag.com/new-periodic-table-elements-confirmed/41139/
Chemistry textbooks are in need of a rewrite with the addition of
four new elements to the Periodic Table. The International Union of Pure
and Applied Chemistry (IUPAC) has confirmed the existence of four new
elements with the atomic numbers 113, 115, 117, and 118, which were
discovered by laboratories in Japan, the United States, and Russia. This
bumper group of new elements completes the 7th row of the Periodic
Table and clears the way for the discoverers to start thinking up names
for them.
Until now, elements 113, 115, 117, and 118 have only
been known from their gaps in the table and the temporary names
ununtrium (Uut), ununpentium (Uup), ununseptium (Uus), and ununoctium
(Uuo). Now, thanks to RIKEN in Japan; the Joint Institute for Nuclear Research in Dubna, Russia; Lawrence Livermore National Laboratory
(LLNL), California; and Oak Ridge National Laboratory, (ORNL),
Tennessee, these elements that do not exist in nature have been
confirmed to have been created for the first time.
The fourth IUPAC and the International Union of Pure
and Applied Physics (IUPAP) Joint Working Party (JWP) reviewed the
findings of the discoverers and, based on a criteria set out in 1991,
have confirmed them. Elements 115 and 117 were found by the Joint
Institute for Nuclear Research, LLNL, and ORNL. Element 118 was found by
the Joint Institute and LLNL, and 113 was found by RIKEN.
The periodic table in its modern form was invented by Russian
chemistry professor Dmitri Mendeleev in 1869 and lists elements
according to their atomic numbers based on the number of protons in
their nuclei. Its odd shape, which is familiar to anyone trying to stay
awake in chemistry class, is due to the discovery that by arranging the
elements to group them by their chemical properties and electron
configurations, it becomes a graphic representation of objective
reality.
In other words, chemists could not only use the table
to describe known elements, but also predict the existence and
properties of unknown elements that were yet to be discovered. This
makes the IUPAC announcement particularly important because it means
that an entire row or period of the table has now been filled in thanks,
in part, to this predictability.
Though many of the new elements were discovered as
far back as 2004, the tricky bit has been proving that they exist. In
the 19th century, any competent chemist could determine if a substance
was a pure element, but the new elements reside in a part of the table
where the atoms are super heavy and so unstable that they exist for less
than a thousandth of a second.
Element 113, for example, was created by using a
linear accelerator to bombard a thin layer of bismuth with zinc ions
travelling at about ten percent of the speed of light in hope that, in
rare instances, the bismuth and zinc atoms would fuse to form a element.
The resulting super-heavy atom of 113 would then decay and turn into
other unstable radioactive isotopes, which would decay nearly as fast.
The result was that the scientists who created the
new element had to spend years tracing back the event through a
labyrinth of isotopic breakdowns to prove that they descended from the
new element. Then, the JWP of the IUPAC had to review the literature to
make sure no mistakes were made.
Now that the elements are confirmed, the discoverers
can officially apply permanent names and symbols to them. The proposed
names and two-letter symbols will be checked by the Inorganic Chemistry
Division of IUPAC and then be subjected to a public review for five
months to make sure they conform to the standards of consistency,
translatability into other languages, and historic use. Typically, names
have been derived from mythology, minerals, geography, or the name of a
scientist.
One other interesting point about the new elements is
that it opens the way to the search for an "island of stability." That
is, a region beyond the current Periodic Table where new superheavy
elements will become stable and exist long enough to allow for
conventional chemistry experiments.

The perfect liquid -- now even more perfect
January 17, 2012
Ultra
hot quark-gluon-plasma, generated by heavy-ion collisions in particle
accelerators, is supposed to be the "most perfect fluid" in the world.
Previous theories imposed a limit on how "liquid" fluids can be. Recent
results at the Vienna University of Technology suggest that this limit
can be broken -- making the world's "most perfect fluid" even more
perfect.
How liquid can a fluid be? This is a question
particle physicists at the Vienna University of Technology have been
working on. The "most perfect liquid" is nothing like water, but the
extremely hot quark-gluon-plasma which is produced in heavy-ion
collisions at the Large Hadron Collider at CERN. New theoretical results
at Vienna UT show that this quark-gluon plasma could be even less
viscous than was deemed possible by previous theories. The results were
published in Physical Review Letters and highlighted as an "editors'
selection".
Highly viscous liquids (such as honey) are
thick and have strong internal friction, quantum liquids, such as super
fluid helium can exhibit extremely low viscosity. In 2004, theorists
claimed that quantum theory provided a lower bound for viscosity of
fluids. Applying methods from string theory, the lowest possible ratio
of viscosity to the entropy density was predicted to be ħ/4π (with the
Planck-constant ħ). Even super fluid helium is far above this threshold.
In 2005, measurements showed that quark-gluon-plasma exhibits a
viscosity just barely above this limit. However, this record for low
viscosity can still be broken, claims Dominik Steineder from the
Institute for Theoretical Physics at Vienna UT. He obtained this
remarkable result working as a PhD-student with Professor Anton Rebhan.

Linear particle accelerator
https://en.wikipedia.org/wiki/Linear_particle_accelerator
A linear particle accelerator (often shortened to linac) is a type of particle accelerator that greatly increases the kinetic energy of charged subatomic particles or ions by subjecting the charged particles to a series of oscillating electric potentials along a linear beamline; this method of particle acceleration was invented by Leó Szilárd. It was patented in 1928 by Rolf Widerøe, who also built the first operational device at the RWTH Aachen University in 1928, influenced by a publication of Gustav Ising.
Linacs have many applications: they generate X-rays and high energy electrons for medicinal purposes in radiation therapy,
serve as particle injectors for higher-energy accelerators, and are
used directly to achieve the highest kinetic energy for light particles
(electrons and positrons) for particle physics.
The design of a linac depends on the type of particle that is being accelerated: electrons, protons or ions. Linacs range in size from a cathode ray tube (which is a type of linac) to the 3.2-kilometre-long (2.0 mi) linac at the SLAC National Accelerator Laboratory in Menlo Park, California.

Seeding magnetic fields for laser-driven flux compression in high-energy-density plasmas.
2009 Apr
A compact, self-contained magnetic-seed-field generator (5 to 16 T) is
the enabling technology for a novel laser-driven flux-compression scheme
in laser-driven targets. A magnetized target is directly irradiated by a
kilojoule or megajoule laser to compress the preseeded magnetic field
to thousands of teslas. A fast (300 ns), 80 kA current pulse delivered
by a portable pulsed-power system is discharged into a low-mass coil
that surrounds the laser target. A >15 T target field has been
demonstrated using a <100 J capacitor bank, a laser-triggered switch,
and a low-impedance (<1 Omega) strip line. The device has been
integrated into a series of magnetic-flux-compression experiments on the
60 beam, 30 kJ OMEGA laser [T. R. Boehly et al., Opt. Commun. 133, 495
(1997)]. The initial application is a novel magneto-inertial fusion
approach [O. V. Gotchev et al., J. Fusion Energy 27, 25 (2008)] to
inertial confinement fusion (ICF), where the amplified magnetic field
can inhibit thermal conduction losses from the hot spot of a compressed
target. This can lead to the ignition of massive shells imploded with
low velocity-a way of reaching higher gains than is possible with
conventional ICF.

Scientists in Germany switch on nuclear fusion experiment (Update)
February 3, 2016
http://phys.org/news/2016-02-scientists-germany-nuclear-fusion.html
Scientists
in Germany flipped the switch Wednesday on an experiment they hope will
advance the quest for nuclear fusion, considered a clean and safe form
of nuclear power.
Following nine years of construction
and testing, researchers at the Max Planck Institute for Plasma Physics
in Greifswald injected a tiny amount of hydrogen into a doughnut-shaped
device—then zapped it with the equivalent of 6,000 microwave ovens.
The
resulting super-hot gas, known as plasma, lasted just a fraction of a
second before cooling down again, long enough for scientists to
confidently declare the start of their experiment a success.
"Everything
went well today," said Robert Wolf, a senior scientist involved with
the project. "With a system as complex as this you have to make sure
everything works perfectly and there's always a risk."
Among
the difficulties is how to cool the complex arrangement of magnets
required to keep the plasma floating inside the device, Wolf said.
Scientists looked closely at the hiccups experienced during the start-up
of the Large Hadron Collider in Switzerland more than five years ago to
avoid similar mistakes, he said.
The experiment in
Greifswald is part of a world-wide effort to harness nuclear fusion, a
process in which atoms join at extremely high temperatures and release
large amounts of energy that's similar to what occurs inside the sun.
Advocates
acknowledge that the technology is probably many decades away, but
argue that—once achieved—it could replace fossil fuels and conventional
nuclear fission reactors.
Construction has already
begun in southern France on ITER, a huge international research reactor
that uses a strong electric current to trap plasma inside a
doughnut-shaped device long enough for fusion to take place. The device,
known as a tokamak, was conceived by Soviet physicists in the 1950s and
is considered fairly easy to build, but extremely difficult to operate.
The
team in Greifswald, a port city on Germany's Baltic coast, is focused
on a rival technology invented by the American physicist Lyman Spitzer
in 1950. Called a stellarator, the device has the same doughnut shape as
a tokamak but uses a complicated system of magnetic coils instead of a
current to achieve the same result.

Small-scale nuclear fusion may be a new energy source
- September 25, 2015
Fusion energy may soon be used in small-scale power stations. This means
producing environmentally friendly heating and electricity at a low
cost from fuel found in water. Both heating generators and generators
for electricity could be developed within a few years, according to new
research.
Nuclear fusion is a process whereby atomic nuclei melt together and
release energy. Because of the low binding energy of the tiny atomic
nuclei, energy can be released by combining two small nuclei with a
heavier one. A collaboration between researchers at the University of
Gothenburg and the University of Iceland has been to study a new type of
nuclear fusion process. This produces almost no neutrons but instead
fast, heavy electrons (muons), since it is based on nuclear reactions in
ultra-dense heavy hydrogen (deuterium).

Magnetic fields and lasers elicit graphene secret
Nov 24, 2014

http://phys.org/news/2014-11-magnetic-fields-lasers-elicit-graphene.html
Graphene
is considered a "wonder material": its breaking strength is higher than
steel and it conducts electricity and heat more effectively than
copper. As a two-dimensional structure consisting of only a single layer
of carbon atoms, it is also flexible, nearly transparent and
approximately one million times thinner than a sheet of paper.
Furthermore, shortly after its discovery ten years ago, scientists
recognized that the energy states of graphene in a magnetic field -
known as Landau levels - behave differently than those of
semiconductors. "Many fascinating effects have been discovered with
graphene in magnetic fields, but the dynamics of electrons have never
been studied in such a system until now," explains physicist Dr. Stephan
Winnerl from HZDR.
The HZDR researchers exposed the
graphene to a four-Tesla magnetic field - forty times stronger than a
horseshoe magnet. As a result, the electrons in graphene occupy only
certain energy states. The negatively charged particles were virtually
forced on tracks. These energy levels were then examined with
free-electron laser light pulses at the HZDR. "The laser pulse excites
the electrons into a certain Landau level. A temporally delayed pulse
then probes how the system evolves," explains Martin Mittendorff,
doctoral candidate at the HZDR and first author of the paper.
Electron redistribution surprises scientists
The
result of the experiments has astonished the researchers. This
particular energy level, into which new electrons were pumped using the
laser, gradually emptied. Winnerl illustrates this paradoxical effect
using an everyday example: "Imagine a librarian sorting books on a
bookshelf with three shelves. She places one book at a time from the
lower shelf onto the middle shelf. Her son is simultaneously 'helping'
by taking two books from the middle shelf, placing one of them on the
top shelf, the other on the bottom. The son is very eager and now the
number of books on the middle shelf decreases even though this is
precisely the shelf his mother wishes to fill."
Because
there were neither experiments nor theories regarding such dynamics
before, the Dresden physicists initially had difficulty interpreting the
signals correctly. After a number of attempts, however, they found an
explanation: collisions between electrons cause this unusual
rearrangement. "This effect has long been known as Auger scattering, but
no one expected it would be so strong and would cause an energy level
to become depleted," explains Winnerl.
This new
discovery could be used in the future for developing a laser that can
produce light with arbitrarily adjustable wavelengths in the infrared
and terahertz ranges. "Such a Landau-level laser was long considered
impossible, but now with graphene this semiconductor physicists' dream
could become a reality," says Winnerl enthusiastically.

Magnetized target fusion
Magnetized target fusion (MTF) is a relatively new approach to producing fusion power that combines features of magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) approaches. Like the magnetic approach, the fusion fuel is confined at lower density by magnetic fields while it is heated into a plasma.
Like the inertial approach, fusion is initiated by rapidly squeezing
the target to greatly increase fuel density and temperature. Although
the resulting density is far lower than in traditional ICF, it is
thought that the combination of longer confinement times and better heat
retention will let MTF yield the same efficiencies, yet be far easier
to build. The term magneto-inertial fusion (MIF) is similar, but
encompasses a wider variety of arrangements. The two terms are often
applied interchangeably to experiments.

Levitated dipole
A levitated dipole is a nuclear fusion experiment using a solid superconducting torus which is magnetically levitated inside the reactor chamber. It is believed that such an apparatus could contain plasma more efficiently than other fusion reactor designs. The superconductor forms an axisymmetric magnetic field of a nature similar to Earth's or Jupiter's magnetospheres. The machine was run in a collaboration between MIT and Columbia University.
The Levitated Dipole Experiment was funded by the US Department of Energy's Office of Fusion Energy, but funding for the LDX was ended in November 2011 to concentrate resources on Tokamak designs

Plasma research shows promise for future compact accelerators
December 22, 2015
A transformative breakthrough in controlling ion beams allows
small-scale laser-plasma accelerators to deliver unprecedented power
densities. That development offers benefits in a wide range of
applications, including nuclear fusion experiments, cancer treatments,
and security scans to detect smuggled nuclear materials.
"In
our research, plasma uses the energy stored in its electromagnetic
fields to self-organize itself in such a way to reduce the energy-spread
of the laser-plasma ion accelerator," said Sasikumar Palaniyappan of
Los Alamos National Laboratory's Plasma Physics group. "In the past,
most of the attempts to solve this problem required active plasma
control, which is difficult."
Laser-plasma
accelerators shoot a high-energy laser into a cloud of plasma, releasing
a beam of ions, or electrically charged particles, in a fraction of the
distance required by conventional accelerators. The laser generates
electromagnetic fields in the plasma.
Using a computer
simulation called Vector-Particle-In-Cell (VPIC), the Laboratory's team
of physicists and computational scientists developed a scheme that
enlists the electromagnetic fields so the beam essentially contains
itself, reducing the energy spread, making the beam more efficient, and
concentrating more energy on its target.

In plasmonics, 'optical losses' could bring practical gain
January 26, 2016
What
researchers had thought of as a barrier to developing advanced
technologies based on the emerging field of plasmonics is now seen as a
potential pathway to practical applications in areas from cancer therapy
to nanomanufacturing.
Plasmonic materials contain
features, patterns or elements that enable unprecedented control of
light by harnessing clouds of electrons called surface plasmons. It
could allow the miniaturization of optical technologies, bringing
advances such as nano-resolution imaging and computer chips that process
and transmit data using light instead of electrons, representing a
potential leap in performance.
However, the development
of advanced optical technologies using plasmonics has been hampered
because components under development cause too much light to be lost and
converted into heat. But now researchers are finding that this
"loss-induced plasmonic heating" could be key to development of various
advanced technologies, said Vladimir M. Shalaev, co-director of the new
Purdue Quantum Center, scientific director of nanophotonics at the Birck
Nanotechnology Center in the university's Discovery Park and a

The Science of Lightsabers
4 May 2022
No Earthly material can withstand plasma at these temperatures, and it must be held away from the walls of the reactor by extraordinarily powerful magnetic fields.
The resulting ‘magnetic bottle’ used to confine the plasma in ITER, and many other fusion reactors is called a tokamak, a doughnut-shaped vacuum chamber surrounded by magnetic coils.
Magnetic fields are the key to containing the plasma in a lightsaber too, speculates Felici, though he adds that a plasma capable of cutting through steel would not have to be anything like as hot as that required for nuclear fusion, merely a few thousand degrees...

Magnetic control of tokamak plasmas through deep reinforcement learning
16 February 2022
Abstract
Nuclear fusion using magnetic confinement, in particular in the tokamak configuration, is a promising path towards sustainable energy. A core challenge is to shape and maintain a high-temperature plasma within the tokamak vessel. This requires high-dimensional, high-frequency, closed-loop control using magnetic actuator coils, further complicated by the diverse requirements across a wide range of plasma configurations. In this work, we introduce a previously undescribed architecture for tokamak magnetic controller design that autonomously learns to command the full set of control coils. This architecture meets control objectives specified at a high level, at the same time satisfying physical and operational constraints. This approach has unprecedented flexibility and generality in problem specification and yields a notable reduction in design effort to produce new plasma configurations. We successfully produce and control a diverse set of plasma configurations on the Tokamak à Configuration Variable1,2, including elongated, conventional shapes, as well as advanced configurations, such as negative triangularity and ‘snowflake’ configurations. Our approach achieves accurate tracking of the location, current and shape for these configurations. We also demonstrate sustained ‘droplets’ on TCV, in which two separate plasmas are maintained simultaneously within the vessel. This represents a notable advance for tokamak feedback control, showing the potential of reinforcement learning to accelerate research in the fusion domain, and is one of the most challenging real-world systems to which reinforcement learning has been applied.

New 'water batteries' stay cool under pressure
February 21, 2024
A global team of researchers and industry collaborators led by RMIT University has invented recyclable 'water batteries' that won't catch fire or explode.
Lithium-ion energy storage dominates the market due to its technological maturity, but its suitability for large-scale grid energy storage is limited by safety concerns with the volatile materials inside.
Lead researcher Distinguished Professor Tianyi Ma said their batteries were at the cutting edge of an emerging field of aqueous energy storage devices, with breakthroughs that significantly improve the technology's performance and lifespan.
"What we design and manufacture are called aqueous metal-ion batteries—or we can call them water batteries," said Ma, from RMIT's School of Science.
The team uses water to replace organic electrolytes—which enable the flow of electric current between the positive and negative terminals—meaning their batteries can't start a fire or blow up—unlike their lithium-ion counterparts.
"Addressing end-of-life disposal challenges that consumers, industry, and governments globally face with current energy storage technology, our batteries can be safely disassembled, and the materials can be reused or recycled," Ma said.
The simplicity of manufacturing processes for their water batteries helped make mass production feasible, he said.
"We use materials such as magnesium and zinc that are abundant in nature, inexpensive, and less toxic than alternatives used in other kinds of batteries, which helps to lower manufacturing costs and reduces risks to human health and the environment."

Why This NASA Battery May Be The Future of Energy Storage
Jul 18, 2023
What
do you do if a satellite runs out of batteries? It’s prohibitively
expensive to send a team into orbit and pop in some new AAs, and as a
result many satellites use very efficient, reliable and long-lived
nickel-hydrogen batteries. We’re talking about batteries that last
decades. That sounds like the sort of battery that could revolutionize
grid-scale energy storage and really help out renewables back here on
Earth, which is why EnerVenue is backing nickel hydrogen batteries as
the next step forward! But if batteries rugged and powerful enough for
spacecraft already exist, then why haven’t we used it back here on Earth

Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new "wood battery" could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage.

Trees are source for high-capacity, soft batteries
Jun 01, 2015

A method for making elastic high-capacity batteries from wood pulp was unveiled by researchers in Sweden and the US. Using nanocellulose broken down from tree fibres, a team from KTH Royal Institute of Technology and Stanford University produced an elastic, foam-like battery material that can withstand shock and stress.
"It is possible to make incredible materials from trees and cellulose," says Max Hamedi, who is a researcher at KTH and Harvard University. One benefit of the new wood-based aerogel material is that it can be used for three-dimensional structures.
"There are limits to how thin a battery can be, but that becomes less relevant in 3D, " Hamedi says. "We are no longer restricted to two dimensions. We can build in three dimensions, enabling us to fit more electronics in a smaller space."

Photonic crystals are
optical nanostructures that are tuned to specific wavelengths of light.
If you understand how semiconductors affect the motion of electrons
(i.e. the bandgap only allows electrons with a certain energy level to
pass through), photonic crystals are the optical equivalent. In this
case, MIT has created infrared-absorbing photonic crystals using metals
such as tungsten and titanium. Because of their metallic roots, these
photonic crystals can operate at temperatures up to 1200C (2192F).

From allergens to anodes: Pollen derived battery electrodes
February 5, 2016
Pollens, the bane of
allergy sufferers, could represent a boon for battery makers: Recent
research has suggested their potential use as anodes in lithium-ion
batteries.
"Our findings have demonstrated that
renewable pollens could produce carbon architectures for anode
applications in energy storage devices," said Vilas Pol, an associate
professor in the School of Chemical Engineering and the School of
Materials Engineering at Purdue University.
Batteries
have two electrodes, called an anode and a cathode. The anodes in most
of today's lithium-ion batteries are made of graphite. Lithium ions are
contained in a liquid called an electrolyte, and these ions are stored
in the anode during recharging.
The researchers tested bee pollen- and cattail pollen-derived carbons as anodes.
"Both
are abundantly available," said Pol, who worked with doctoral student
Jialiang Tang. "The bottom line here is we want to learn something from
nature that could be useful in creating better batteries with renewable
feedstock."
Research findings are detailed in a paper that appeared on Feb. 5 in Nature's Scientific Reports.
Whereas bee pollen is a mixture of different pollen types collected by honey bees, the cattail pollens all have the same shape.
"I
started looking into pollens when my mom told me she had developed
pollen allergy symptoms about two years ago," Tang said. "I was
fascinated by the beauty and diversity of pollen microstructures. But
the idea of using them as battery anodes did not really kick in until I
started working on battery research and learned more about carbonization
of biomass."
The researchers processed the pollen
under high temperatures in a chamber containing argon gas using a
procedure called pyrolysis, yielding pure carbon in the original shape
of the pollen particles. They were further processed, or "activated," by
heating at lower temperature - about 300 degrees Celsius - in the
presence of oxygen, forming pores in the carbon structures to increase
their energy-storage capacity.

New alloy claimed to have higher strength-to-weight ratio than any other metal
December 11, 2014
When it comes to metal that's being used in the automotive or
aerospace industries, the higher its strength-to-weight ratio, the
better. With that in mind, researchers from North Carolina State
University and Qatar University have developed a new alloy that
reportedly has a low density similar to that of aluminum, but that's
stronger than titanium.
The material is a type of high-entropy alloy, meaning
that it's made up of at least five metals in more or less equal
amounts. In this case, those metals are lithium, magnesium, titanium,
aluminum and scandium.
"It has a combination of high strength and low
density that is, as far as we can tell, unmatched by any other metallic
material," said NCSU's Dr. Carl Koch, senior author of a paper on the
research. "The strength-to-weight ratio is comparable to some ceramics,
but we think it’s tougher – less brittle – than ceramics."
He additionally informed us that while carbon fiber
very likely has a higher strength-to-weight ratio than the alloy, it
also wouldn't be as tough – in other words, the alloy would be more
likely to bend under an amount of stress that would cause the carbon to
fracture.
More work still has to be done in the testing of the
alloy, along with establishing a practical production method. Koch and
his colleagues are also looking into replacing or eliminating the
scandium that makes up 20 percent of the material, as it's very
expensive.

An Israeli research team conducted by Prof. Yair Ein-Eli
at the Technion – Israel Institute of Science, has recently developed a
new battery that is able to produce thousands of hours of charge from
an abundant and non-polluting fuel source.
This new portable battery could
replace the batteries used in hearing aids, due to its reduced

the researchers, in the near future it can replace laptop batteries
as we known them, allowing them to run for hundreds of hours on a

a couple of years. “This would take about 10 years more and be
revolutionary,” said Ein-Eli.
The current prototypes of the battery have a silicon power source that reverts back to their original form as sand. “In the paper, we showed that at 600 hours it had used only 10 percent of the energy. So we are talking about 6,000 hours,” says the professor.

Newly Discovered Property of Graphene to Boost Fuel Cells Efficiency
November 28, 2014
The founder of graphene discovered one more incredible property of the material that can give the ever-so-needed to boost fuel cells and hydrogen-based technologies. The strongest, thinnest, and initially known as impermeable material, in fact allows hydrogen protons to pass through.
No wonder graphene is labelled as the “miracle material”. Every property or use of it that is discovered, opens up a great deal of new and super exciting opportunities and applications. Of course, there is no one, who better understands graphene than its discoverer- the Nobel prize winner Andre Geim of University of Manchester, and therefore it is no surprise that exactly his team has found yet another super exciting property of the thin super-strong material.
In the study published this week in the journal Nature, the team describes how at high temperatures, above 250 degrees Celsius, graphene allows hydrogen protons to pass through. In addition, this process of proton transport can be enhanced by adding an extra layer of catalytic metal nanoparticles, such as platinum. This great discovery has a potential in improving the performance of fuel cells. Here, it could act as a proton-conducting membrane, which could potentially eliminate the pressing problem of fuel leaks, associated with reduction of cell efficiency. This property also opens up new horizons for development of exciting hydrogen-based technologies.

A Married Couple’s Sweet Music – A Graphene Battery Printing
October 25, 2014
http://www.greenoptimistic.com/married-couples-sweet-music-graphene-battery-printing-20141025/#.VSFr_eG-2zk
This couple is making beautiful music together – they’ve printed a battery made of graphene.
Dr. Elena Polyakova and Dr. Daniel Stolyarov, originally from Russia,
founded Graphene 3D Lab and have since moved the company to Calverton,
New York. They spent more than five years researching raw materials
that can be used to make a graphene battery using a 3D printer.
Graphene is a special form of carbon in which the atoms are arranged
in a hexagonal lattice along a single layer. In this configuration, the
carbon is 200 times stronger than steel and it conducts electricity 30
times faster than silicon. It is the latter feature that makes it ideal
for making tough composites, computer chips and well, batteries. Already batteries with lives 25 percent longer than lithium-ion batteries have already been made by other researchers.
Graphene 3D Lab’s design has one up on the competition, however,
because it can be made anywhere and practically in any shape.
Although
the prototype is able to produce the same amount of power as a common
AA battery, it has already produced considerable interest from the
military, as well as from the aerospace and car industries, according to
Dr. Polyakova, Graphene 3D Lab’s CoO. The company’s technology allows
one to print batteries to fit crooks and nannies where space is tight.
It can be used to print other graphene parts. As such, this technology
is very useful for space missions. Dr. Polyakova says, “That is an
exotic example, but a good one. A mission of that kind requires
thousands of spare parts and dozens of different battery types. Our
technology could remove the need to carry replacement batteries.”

Renewable energy from evaporating water (w/ Video)
June 16, 2015
(The "moisture mill" is a new kind of turbine engine that turns
continuously as water evaporates from the wet paper lining the walls of

An immensely powerful yet invisible force pulls water from the
earth to the top of the tallest redwood and delivers snow to the tops of
the Himalayas. Yet despite the power of evaporating water, its
potential to propel self-sufficient devices or produce electricity has
remained largely untapped—until now.

World's first "aqueous solar flow battery" outperforms traditional lithium-iodine batteries
August 3, 2015
The scientists that revealed the "world's first solar battery"
last year are now, following some modifications, reporting its first
significant performance milestone. The device essentially fits a battery
and solar cell into the one package, and has now been tested against
traditional lithium-iodine batteries, over which the researchers are
claiming energy savings of 20 percent.
It was last October that researchers at Ohio State University (OSU)
first detailed their patent-pending design for a dye-sensitized solar
cell also capable of storing its own power. With three electrodes rather
than the typical four, it featured a lithium plate base, two layers of
electrode separated by a thin sheet of porous carbon, and a titanium
gauze mesh that played host to a dye-sensitive titanium dioxide
photoelectrode.
The reasoning behind the porous nature of the
materials was to allow the battery's ions to oxidize into lithium
peroxide, which was in turn chemically decomposed into lithium ions and
stored as lithium metal. But the team has redesigned the battery so that
air no longer needs to pass through it in order to function.

Andrea Rossi’s E-Cat — the

or “far more than can be obtained from any known chemical sources in the
small reactor volume.” The researchers were also allowed to analyze the
fuel before and after the 32-day run, noting that the isotopes in the
spent fuel could only have been obtained by “nuclear reactions” — a
conclusion that boggles the researchers: “… It is of course very hard to
comprehend how these fusion processes can take place in the fuel
compound at low energies.”

MIT Physicists Create Ultracold Molecules of 23Na40K
A team of physicists from MIT has successfully cooled molecules
in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins,
creating ultracold molecules.
The air around us is a chaotic superhighway of molecules whizzing
through space and constantly colliding with each other at speeds of
hundreds of miles per hour. Such erratic molecular behavior is normal at
ambient temperatures.
But scientists have long suspected that if temperatures were to
plunge to near absolute zero, molecules would come to a screeching halt,
ceasing their individual chaotic motion and behaving as one collective
body. This more orderly molecular behavior would begin to form very
strange, exotic states of matter — states that have never been observed
in the physical world.
Now experimental physicists at MIT have successfully cooled molecules
in a gas of sodium potassium (NaK) to a temperature of 500 nanokelvins —
just a hair above absolute zero, and over a million times colder than
interstellar space. The researchers found that the ultracold molecules
were relatively long-lived and stable, resisting reactive collisions
with other molecules. The molecules also exhibited very strong dipole
moments — strong imbalances in electric charge within molecules that
mediate magnet-like forces between molecules over large distances.

Cold Atom Laboratory
researchers used lasers to optically cool rubidium atoms to temperatures
almost a million times colder than that of the depths of space. The
atoms were then magnetically trapped, and radio waves were used to cool
the atoms 100 times lower. The radiofrequency radiation acts like a
knife, slicing away the hottest atoms from the trap so that only the
coldest remain.
The research is at the point where this process can reliably create a Bose-Einstein condensate in just seconds.
"This
was a tremendous accomplishment for the CAL team. It confirms the
fidelity of the instrument system design and provides us a facility to
perform science and hardware verifications before we get to the space
station," said CAL Project Manager Anita Sengupta of JPL.
While
so far, the Cold Atom Laboratory researchers have created Bose-Einstein
condensates with rubidium atoms, eventually they will also add in
potassium. The behavior of two condensates mixing together will be
fascinating for physicists to observe, especially in space.
Besides
merely creating Bose-Einstein condensates, CAL provides a suite of
tools to manipulate and probe these quantum gases in a variety of ways.
It has a unique role as a facility for the atomic, molecular and optical
physics community to study cold atomic physics in microgravity, said
David Aveline of JPL, CAL ground testbed lead.

New method for creating transparent magnetic materials using laser heating
Dec 14, 2023
https://phys.org/news/2023-12-method-transparent-magnetic-materials-laser.html
In
a significant advancement in optical technology, researchers from
Tohoku University and Toyohashi University of Technology have developed a
new method for creating transparent magnetic materials using laser
heating. This breakthrough, recently published in the journal Optical
Materials, presents a novel approach to integrating magneto-optical
materials with optical devices, a long-standing challenge in the field.
"The
key to this achievement lies in creating Cerium-substituted Yttrium
Iron Garnet (Ce:YIG), a transparent magnetic material, employing a
specialized laser heating technique," says Taichi Goto, associate
professor at Tohoku University's Electrical Communication Research
Institute (RIEC) and co-author of the study. "This method addresses the
key challenge of integrating magneto-optical materials with optical
circuits without damaging them—a problem that has hindered advancements
in miniaturizing optical communication devices."
Magneto-optical
isolators are vital for ensuring stable optical communication. They act
like traffic directors for light signals, allowing them to move in one
direction but not the other. Integrating these isolators into
silicon-based photonic circuits is challenging due to the
high-temperature processes typically involved.
As a result of
this conundrum, Goto and his colleagues focused their attention on laser
annealing—a technique that selectively heats specific areas of a
material by laser. This allows for precise control, influencing only the
targeted regions without affecting surrounding areas.
Previous
studies had used this to selectively heat bismuth-substituted yttrium
iron garnet (Bi: YIG) films deposited on a dielectric mirror. This
allows the Bi:YIG to crystalize without affecting the dielectric mirror.
However,
when working with Ce:YIG, an ideal material for optical devices due to
its magnetic and optical properties, problems arise because exposure to
the air results in unwanted chemical reactions.
To avoid this,
the researchers engineered a new device that heats materials in a
vacuum, i.e., without air, using a laser. This allowed for precise
heating of small areas (about 60 micrometers) without altering the
surrounding material.
"The transparent magnetic material created
through this method is expected to significantly enhance the development
of compact magneto-optical isolators, crucial for stable optical
communication," says Goto. "Additionally, it opens avenues for creating
powerful miniaturized lasers, high-resolution displays, and small
optical devices."

Manipulation of polarizations for broadband terahertz waves emitted from laser plasma filaments
27 August 2018
Abstract
Polarization
control of broadband terahertz waves is essential for applications in
many areas, such as materials science, medical and biological
diagnostics, near-field communications and public securities.
Conventional methods for polarization control are limited to narrow
bandwidth and often with low efficiency. Here, based on theoretical and
experimental studies, we demonstrate that the two-colour laser scheme in
gas plasma can provide effective control of elliptically polarized
terahertz waves, including their ellipticity, azimuthal angle and
chirality. This is achieved with a circularly polarized laser at the
fundamental frequency and its linearly polarized second harmonic, a
controlled phase difference between these two laser components, as well
as a suitable length of the laser plasma filament. Flexible control of
ellipticity and azimuthal angle is demonstrated with our theoretical
model and systematic experiments. This offers a unique and flexible
technique on the polarization control of broadband terahertz radiation
suitable for a wide range of applications.

Image of the inside of a magnetic confinement experiment during plasma discharge. In a tokamak, plasma particles are confined and shaped by magnetic field lines that combine to act like an invisible bottle. Pictured, the spherical tokamak MAST at the Culham Centre for Fusion Energy (UK), where over 30,000 man-made ”stars” have been created.
What Is Plasma Confinement?
Plasma confinement refers to the containment of a plasma by various forces at the extreme conditions necessary for thermonuclear fusion reactions. These conditions exist naturally in stars, where they are sustained by the force of gravity. In the laboratory, researchers use strong magnetic fields to confine plasma. This magnetic confinement strategy may allow them to confine fusion grade plasmas over the long term. Another confinement strategy relies on the inertia of imploding matter. This inertial confinement strategy has been demonstrated on Earth in hydrogen bomb detonations and specialized facilities. Inertial confinement is an active research area. Laboratories use high power lasers or electrical discharges, to compress hydrogen fuel to very high densities for billionths of a second.
Plasma Confinement Facts
Magnetically confined plasmas have achieved temperatures 10 times hotter than the core of our sun.
ITER will be the first burning plasma in the world. It aims to generate 500 megawatts of fusion power–10 times more power than will be injected. NIF is the most energetic laser in the world with 2 megajoules of light energy (the energy consumed by 20,000 100-watt light bulbs in one second) delivered in 16 nanoseconds.

Magnetic confinement fusion
Magnetic confinement fusion (MCF) is an approach to generate thermonuclear fusion power that uses magnetic fields to confine fusion fuel in the form of a plasma. Magnetic confinement is one of two major branches of controlled fusion research, along with inertial confinement fusion.

The new approach could be used for satellite recovery, delivery missions and deflecting space debris
In the science fiction universe of Hollywood’s Star Wars, the Jedi are able to use the Force to move objects around without physical contact, a manoeuvre referred to as “Force push” or “Force pull”.
The ability allows the Jedi to levitate themselves or others, and to manipulate objects in more complex ways, such as constructing structures or repairing machinery...

Plasma magnet
A
plasma magnet is a proposed spacecraft propulsion device that uses a
dipole magnetic field to capture energy from the solar wind. The field
acts as a sail, using the captured energy to propel the spacecraft
analogously to how the wind propels a sailing vessel. It could
accelerate a vessel moving away from the sun and decelerate it when
approaching a distant star at the end of an interstellar journey. Thrust
vectoring and steering could be achieved by manipulating the dipole
tilt for any type of magnetic sail.

DARPA Launches Falcon HTV-2 Glider, the World's Fastest Plane
August 11, 2011
At 7:45 a.m. PDT, an unmanned glider was launched from Vandenberg Air Force Base in California aboard a Minotaur 4 rocket. Overseen by DARPA, the Defense Advanced Research Projects Agency, the glider, named HTV-4, is expected to reach suborbital space before reentering Earth's atmosphere at Mach 20 with the help of rocket thrusters to stay on course. If the hypersonic glider is able to reach Mach 20, or about 13,000 mph, it will become the fastest plane ever. At that speed, the HTV-2 could travel from New York City to Los Angeles in about 12 minutes...

Is This Accidental Discovery The Future Of Energy?
Oct 10, 2023
Imagine
getting the energy needed to power our phones, light up our homes, or
drive our cars, from thin air. And no, we’re not talking about Nikola
Tesla’s dream of wireless power a century ago, but a new and accidental
discovery along those lines from the University of Massachusetts
Amherst. Researchers have found a way to turn humidity into electricity.
It’s called hygroelectrical power, and believe it or not, a company
named CascataChuva is already trying to commercialize a variant of the
technology. So, what is it and how does it work?

The French Army flew an airship named La France in 1884, and the first hot air balloon flew in 1783. But a series of high profile crashes like the Hindenburg and R101, and the considerably faster evolution of aircraft saw airships fall out of favour (except for a subsection of the marketing industry).
Hot air balloons aren’t known for their ease of navigation or speed, and airships, whilst easier to control and faster, are still too slow to have a meaningful impact on the markets they have been targeting up to now.
All that being said, UK-based startup SkyLifter thinks it has a found a new use case. Deciding there was no aerospace use case that could be improved versus what is currently available today for passengers, cargo and earth observation, the firm identified a niche in the construction industry it thinks can only be exploited by the capabilities of airship technology.
The startup is building a “commercial hook-in-the-sky system” made up of a gas-filled omni-directional lenticular-shaped aerostat (aka lighter-than-air aircraft) with an underslung pod housing the propulsion system, winch and hook. The pod, which also serves to aid the craft’s stability by increasing the vertical distance between the centre of buoyancy and the centre of gravity, houses the main aircraft systems for power, control and communication.
SkyLifter’s omni-directional propellers enable thrust in all directions and allow it to achieve an airspeed of about 45 knots (51mph). There is also the option to float “endlessly” without power, according to founder and CEO Jeremy Fitton, “at least in theory”.

Were the stone blocks carved from natural limestone or cast with an early version of concrete? A materials science research team provides evidence to answer this age-old mystery.

What Materials Were Used To Build The Pyramids Of Giza?
2018
Limestone
Limestone was one of the materials used to build the Pyramids of Giza. It formed the bulk of the materials used in the construction of the pyramids and rough limestone was utilized in the core of the pyramid. White limestone, which is finer, was used to coat the interior walls and as the main material for the outer casing. The low-grade limestone that was used in the core of the pyramids is found huge quantities in Egypt, and it was found near the building sites during the pyramid construction era. Workers extracted the stone in blocks by marking out crevices with just enough room for them to be cut into blocks and transported to the sites. Tools used in this case included chisels, pickaxes, and hammers made from granite.
The fine white limestone for the interior décor and the mortuary temples was slightly hard to extract and had to be sourced further away from the building sites. This type of limestone was found deeper beneath the soil surface in regions including the West bank of the Nile in the hills of Muqattam in the present day regions of Maasara and Tura. The workmen would excavate the soil and dig tunnels to reach the deposits which would be as deep as 160 feet below the surface. Huge pieces of stone were then dug up to be divided into blocks which were then transported on wooden sledges towed by oxen on a path paved with mud from the Nile to make movement easier to the construction site.
Pink Granite
The granite was used in conjunction with limestone to cover the interior walls of the pyramids though much more sparingly since it was distributed in several parts of South of Egypt and was not as close as the limestone quarries were to the building sites. Pink granite is thought to have been mined in Aswan which had some quarries.
Basalt
Basalt is also known as alabaster and it was often used to cover the floor of the pyramid. It was extracted from open pits or underground deposits, particularly from an Oligocene flow where there was once a lake that connected to the Nile. During this time the basalt was transported on the lake and into the Nile to its shores where it was moved to the construction site of the pyramids.
Mud Bricks
Mud bricks were perhaps the most common building material in all of Egypt. In the pyramids it was used to build the walls, these were fired in an oven as a measure to make them last longer.
Significance
Like the Eiffel Tower of France and the Colosseum in Rome, the Pyramids of Giza are a defining landmark in Egypt and an important part of the culture of the people of Egypt. The impressive architecture that began years ago is proof of the heights of human achievement of the past.

Why aren't Rogallo wings or parafoils used in aircraft with fuselages?
2016
Ultralights and paragliders: Only categories with Rogallo wings
The
advantages provided by flexible wings (easy storage, light weight, low
cost) is a significant choice criteria for use in ultralights and
paragliders, and of course for parachutes. These advantages overcome
their limited aerodynamic performances, which is of lesser consideration
for vehicles that are not specially aerodynamically designed.
To
summarize: The flexible wings are more appropriate for smaller and
slower aircraft, in particular those not requiring wing tanks, wing
control surfaces, or wing landing gears. Namely ultralights.
Controls-
The wings house the controls, which would not be possible in case of
flexible wings (future combat aircraft are expected to have wing
morphing, but is still a bit far away). The control of flexible wings
are by using cables, which are suitable only for small aircraft. Another
issue is redundancy, which would be quite difficult with these exposed
cables.
Safety- The flexible wings do not offer the same level of
safety as the rigid (elastic) ones. What if they fail to deploy
properly or start to retract in flight? NASA carried out research on the
usage of flexible wings for the spacecraft landing programs which
brought out a number of issues related to structural safety and
deployment:
The wing’s structural problems persisted. Further drop tests saw more sails fall apart ...
Wing deployment tests were also proving problematic. The sail wasn’t
deploying consistently, at times not opening fully and failing to
inflate with enough time...
Even though most of these problems
were fixed, it would have been difficult to convince regulatory
authorities and paying public for their use.
It should be noted
that most of the advantages of the flexible wings are precisely because
of their limitations- it is collapsible for reduced storage and weigh
less because it doesn't carry fuel or have control surfaces and doesn't
have mountings for various things (like navigation lights etc).
It
should noted that the people involved were quite conscious of the
restrictions of this type of wing- For example, Francis M. Rogallo, the
inventor of rogallo wing was quite cautious when he noted,
... if we could discover how to make flexible wings that could be
packaged and deployed somewhat like a parachute, such wings would have
many new applications as well as replacing some parachutes and rigid
wings.

Rogallo wing
https://en.wikipedia.org/wiki/Rogallo_wing
The
Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a
NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating
flexible wing they called the Parawing, also known after them as the
"Rogallo Wing" and flexible wing. NASA considered Rogallo's flexible
wing as an alternative recovery system for the Mercury and Gemini space
capsules, and for possible use in other spacecraft landings, but the
idea was dropped from Gemini in 1964 in favor of conventional
parachutes.

Asynchronous locking in metamaterials of fluids of light and sound
19 June 2023
Abstract
Lattices of exciton-polariton condensates represent an attractive platform for the study and implementation of non-Hermitian bosonic quantum systems with strong non-linear interactions. The possibility to actuate on them with a time dependent drive could provide for example the means to induce resonant inter-level transitions, or to perform Floquet engineering or Landau-Zener-Stückelberg state preparation. Here, we introduce polaromechanical metamaterials, two-dimensional arrays of μm-sized traps confining zero-dimensional light-matter polariton fluids and GHz phonons. A strong exciton-mediated polariton-phonon interaction induces a time-dependent inter-site polariton coupling J(t) with remarkable consequences for the dynamics. When locally perturbed by continuous wave optical excitation, a mechanical self-oscillation sets-in and polaritons respond by locking the energy detuning between neighbor sites at integer multiples of the phonon energy, evidencing asynchronous locking involving the polariton and phonon fields. These results open the path for the coherent control of dissipative quantum light fluids with hypersound in a scalable platform.

Aeroplanes use propellers and turbines, and are typically powered by fossil-fuel combustion. An alternative method of propelling planes has been demonstrated that does not require moving parts or combustion.
Small, lightweight devices called lifters can propel themselves into the air without combustion or moving parts, and have become a popular topic of discussion with technology buffs on social media in the past few years. And yet the physical mechanism behind lifters has been known for more than a century. When charged molecules in the air are subjected to an electric field, they are accelerated.

Researchers look to the boxfish for new body armor materials
July 29th, 2015
Researchers from the University of California, San Diego (UCSD) are taking inspiration from nature in the search for new materials that could one day be used to create more effective body armor. The study, which was supported by the US Air Force, focuses on the unique structure and strength of the hexagonally-scaled shell of the boxfish.
The idea of looking to nature for inspiration when it comes to next-gen armor isn't anything new. We've seen numerous studies over the last few years that focus on that same idea, including efforts to copy the structure of overlapping fish scales and even the properties of sea sponges to develop strong yet flexible armor.

Tiny sea creatures could provide inspiration for armor with built-in optical systems
November 25, 2015
http://www.gizmag.com/mit-chiton-optical-armor/40590/?li_source=LI&li_medium=default-widget
A team of MIT researchers has looked
closer than ever before at the unique shells of chitons, using X-rays
to discover their secrets. The results reveal a no-compromise setup
that provides the tiny sea creatures with both protection and optical
visibility. The findings could one day inspire man-made armor with
similar abilities.
Turning to nature for ideas for new
materials is nothing new. In the past, researchers have looked to
fish scales, boxfish shells and even sea sponges for better body
armor, and we've even seen species of chiton inspiring higher-performing batteries and solar cells.
For the new MIT study, the researchers
worked with a fascinating species of chiton known as Acanthopleura granulata. They have an appearance similar to the rocks amongst which
they're usually found, and are small at only a few inches in diameter.
The creatures have developed a ceramic
shell system that's not only flexible, being comprised of eight
overlapping plates, but also provides high levels of visibility, by
incorporating tiny eyes throughout. Unlike the vast majority of other
living creatures, the chiton's eyes aren't made from portein, but are
instead made up of the mineral aragonite – the same ceramic that
makes up the rest of its shell.

Next-generation body armor could be based on ... sponges?
March 18, 2013
http://www.gizmag.com/sponge-spicule-armor/26700/
Sponges’ “skeletons” – their internal structural elements – are made
up of tiny interlinked needle-like structures known as spicules. These
are hard, prickly, flexible and lightweight. As a result, they offer
enough strength to provide structural support, while they bend to such
an extent that they’re difficult to cut. A team of researchers from
Germany’s Johannes Gutenberg University Mainz and the Max Planck
Institute for Polymer Research set out to develop a material with those
same qualities.
The nanoscale spicules they created incorporate a
mixture of the mineral calcite, and a protein found in siliceous sponges
known as silicatein-α. Each synthetic spicule is composed of a
multitude of calcite “nanobricks” stacked together brick chimney-style,
with a matrix of the stretchy protein holding them together.

Future soldiers may be wearing fish-inspired body armor
March 16, 2015
On most fish, their hard, overlapping scales provide considerable protection against pokes and cuts. Because those independently-moving scales are each attached to a flexible underlying skin, however, the fish are still able to easily twist and turn their bodies. Scientists from the Technion-Israel Institute of Technology and MIT are now attempting to copy that structure, to develop flexible-yet-effective armor for humans.

Fish's piranha-proof scales could lead to tough, flexible body armor
February 10, 2012
http://www.gizmag.com/arapaima-piranha-proof-scales/21419/?li_source=LI&li_medium=default-widget
The Arapaima's "hard on the outside but pliable underneath"
strategy is employed by a number of organisms, that need to be agile
while remaining protected. Meyers believes the principle could find use
in flexible ceramics, that could in turn be applied not only to
soldiers' body armor, but also fuel cells, insulation or aerospace
technology.
Here's a question - if piranhas are so ferocious and will attack
anything, why aren't they the only fish in the Amazon? Well, in some
cases, it's because other fish possess bite-proof armor. The 300-pound
(136-kg) Arapaima is just such a fish. In the dry season, when water levels get low, Arapaima
are forced to share relatively small bodies of water with piranhas.
Their tough-but-flexible scales, however, allow them to remain unharmed.
A scientist from the University of California, San Diego is now taking a
closer look at those scales, with an eye towards applying their secrets
to human technology such as body armor.
MIT Breakthrough could lead to paper-thin bullet-proof armor
Scientists have theorized that paper-thin composite nanomaterials could stop bullets just as effectively as heavy weight body armor, but progress has been hampered by their inability to reliably test such materials against projectile impacts. Researchers at MIT and Rice University have developed a breakthrough stress-test that fires microscopic glass beads at impact-absorbing material. Although the projectiles are much smaller than a bullet, the experimental results could be scaled up to predict how the material would stand up to larger impacts.

The Forest Products Laboratory of the US Forest Service has opened a US$1.7 million pilot plant for the production of cellulose nanocrystals (CNC) from wood by-products materials such as wood chips and sawdust. Prepared properly, CNCs are stronger and stiffer than Kevlar or carbon fibers, so that putting CNC into composite materials results in high strength, low weight products. In addition, the cost of CNCs is less than ten percent of the cost of Kevlar fiber or carbon fiber. These qualities have attracted the interest of the military for use in lightweight armor and ballistic glass (CNCs are transparent), as well as companies in the automotive, aerospace, electronics, consumer products, and medical industries.

Graphene could find use in lightweight ballistic body armor
December 1st, 2014
While graphene
is already known for being the world's strongest material, most studies
have focused on its tensile strength – that's the maximum stress that
it can withstand while being pulled or stretched, before failing.
According to studies conducted at Houston's Rice University, however,
its ability to absorb sudden impacts hadn't previously been thoroughly
explored. As it turns out, the material is 10 times better than steel at
dissipating kinetic energy. That could make it an excellent choice for
lightweight ballistic body armor.

Carbyne is stronger than any known material
August 20, 2013
A paper on Arxiv presents a detailed look at the properties of carbyne, stronger than graphene and diamond, a true supermaterial. The paper is titled, "Carbyne from first principles: Chain of C atoms, a nanorod or a nanorope?" Authors are Mingjie Liu, Vasilii I. Artyukhov, Hoonkyung Lee, Fangbo Xu, and Boris I. Yakobson, from Rice University, in Houston, from the departments of mechanical engineering and materials science, chemistry, and the Smalley Institute for Nanoscale Science and Technology. They have calculated the properties of carbyne. Described as a chain of carbon atoms that are linked by alternate triple and single bonds or by consecutive double bonds, carbyne is of special interest, chemists find, because it is stronger, and stiffer than anything that they have seen before. The discovery of carbyne is not entirely new. Explorations of carbyne have their own history.

As a quick visit to any armored division will make obvious, tanks are

And as anti-tank weapons get better, tanks can only get bigger. To avoid

Liquid metal could be used to create morphing electronics
September 21, 2014
http://www.gizmag.com/liquid-metal-morphing-electronics/33836/
Who could forget the scene in Terminator 2: Judgement Day
where the shape-shifting T-1000 reassembles itself from thousands of
blobs of molten metal? Researchers from North Carolina State University
(NCSU) have taken the first steps to such science fiction becoming
reality by developing a way to control the surface tension of liquid
metals with the application of very low voltages. This may offer
opportunities in a new field of morphing electronic circuits, self-healing electronics, or – one day – maybe even self-assembling terminator-style robots.
The liquid metal used by the researchers was an alloy
of gallium and indium. Gallium is liquid just above room temperature at
about 29° C (84° F), while Indium has a much higher melting point at
around 156° C (312° F), yet when mixed together, they form an alloy that
is liquid at room temperature. In other words, a eutectic
alloy – one that is composed of metals with disparate melting points
that, when combined, melt as a whole at a specific temperature.
Another important aspect of this eutectic alloy, and
one that the researchers sought to exploit in their experiments, is its
exceptionally high surface tension of approximately 500 millinewtons per
meter (mN/m). The consequence of this is that a blob of this alloy
resting on a surface will tend to form an almost spherical ball and hold
its shape if undisturbed...

coated with black carbon grease electrodes.
- The
researchers have shown the artificial skin, made from electroactive
dielectric elastomer, a soft, compliant smart material, can effectively
copy the action of biological chromatophores. Chromatophores are small
pigmented cells embedded on cephalopods skin which can expand and
contract and that work together to change skin colour and texture.
The
system achieves the dynamic pattern generation by using simple local
rules in the artificial chromatophore cells, so that they can sense
their surroundings and manipulate their change. By modelling sets of
artificial chromatophores in linear arrays of cells, the researchers
explored whether the system was capable of producing a variety of
patterns...

Bacterial Armor Holds Clues for Self-Assembling Nanostructures
February 11, 2015
Imagine thousands of copies of a single protein organizing into a coat of
chainmail armor that protects the wearer from harsh and ever-changing
environmental conditions. That is the case for many microorganisms. In a
new study, researchers with the U.S. Department of Energy (DOE)’s
Lawrence Berkeley National Laboratory (Berkeley Lab) have uncovered key
details in this natural process that can be used for the self-assembly
of nanomaterials into complex two- and three-dimensional structures.
Caroline Ajo-Franklin, a chemist and synthetic biologist at Berkeley Lab’s Molecular Foundry,
led this study in which high-throughput light scattering measurements
were used to investigate the self-assembly of 2D nanosheets from a
common bacterial surface layer (S-layer) protein. This protein, called
“SbpA,” forms the protective armor for Lysinibacillus sphaericus, a
soil bacterium used as a toxin to control mosquitoes. Their
investigation revealed that calcium ions play a key role in how this
armor assembles. Two key roles actually.
“Calcium ions not only trigger the folding of the protein into the
correct shape for nanosheet formation, but also serve to bind the
nanosheets together,” Ajo-Franklin says. “By establishing and using
light scattering as a proxy for SbpA nanosheet formation, we were able
to determine how varying the concentrations of calcium ions and SbpA
affects the size and shape of the S-layer armor.”

How Liquid Body Armor Works
http://science.howstuffworks.com/liquid-body-armor1.htm
The fluid used in body armor is made of silica particles suspended in polyethylene glycol. Silica is a component of sand and quartz, and polyethylene glycol is a polymer commonly used in laxatives and lubricants. The silica particles are only a few nanometers in diameter, so many reports describe this fluid as a form of nanotechnology.
To make liquid body armor using shear-thickening fluid, researchers first dilute the fluid in ethanol. They saturate the Kevlar with the diluted fluid and place it in an oven to evaporate the ethanol. The STF then permeates the Kevlar, and the Kevlar strands hold the particle-filled fluid in place. When an object strikes or stabs the Kevlar, the fluid immediately hardens, making the Kevlar stronger.

Quantum Stealth material designed to make target invisible
December 16, 2012
Scientists are exploring better methods of camouflage, a so-called scientific invisibility cloak, and news has spread fast about a Canadian company with substantial claims on how far they have come with camouflage technology. The company, HyperStealth Biotechnology, has developed Quantum Stealth camouflage material, which renders its wearers invisible by bending light waves around them. Their work has obvious implications for the defense industry. How can the enemy hit targets they cannot see or defend themselves from attackers who are invisible? Theoretically, any soldier could put on the material and get it working with no power source required.

New Silkworm Dye Method Could Help Build Silks With Medicinal Properties
Mar 17, 2011
We
pay close attention to the modifications scientists are making to
goats, moths and worms so they can harvest their silk. Now researchers
in Singapore are reporting a new advancement: dyed-in-the-worm silks,
which look pretty and could have interesting medical applications.
Researchers
led by Natalia C. Tansil at the Institute of Materials Research and
Engineering in Singapore fed silkworms a special diet, leading the worms
to produce fluorescent silks of a particular color.
The direct
uptake of dyes produced “intrinsically colored” silks, the researchers
explain — the material comes out already colored. New Scientist says the
worm pictured here ate a diet of mulberries and fluorescent dye, and
produced a lovely rose-colored fiber.
Silkworms, which are pretty
efficient little textile factories, are also being genetically modified
to produce other materials like spider silk, nature’s toughest fiber.
The coloring process doesn’t modify the worms’ genes — it just gives
them a chemical cocktail that makes them produce colorful silk. It could
be a more environmentally friendly way to produce various colors,
rather than using chemicals to dye silk.
The method could also be
used to dope silks with other materials, like antibacterial properties
so they could be used as wound dressings, according to New Scientist.

Tattoo inks found to not match the ingredients listed on the bottle
Feb 2024
The
researchers analyzed tattoo inks from nine manufacturers in the United
States and compared their actual contents with the label. The
manufacturers ran the gamut from major, global companies to smaller
producers; the inks in question came in six colors.
Of the 54
inks, 45 of them—90%—had major discrepancies with the labeled contents,
such as different pigments than the ones listed or unlisted additives.
More
than half contained unlisted polyethylene glycol, which can cause organ
damage through repeated exposure, while 15 contained propylene glycol, a
potential allergen. Other contaminants included an antibiotic commonly
used to treat urinary tract infections and 2-phenoxyethanol, which poses
potential health risks to nursing infants.
Their research cannot

Patina
Patina is a thin layer that variously forms on the surface of stone; on copper, bronze and similar metals (tarnish produced by oxidation or other chemical processes); on wooden furniture
(sheen produced by age, wear, and polishing); or any such acquired
change of a surface through age and exposure. Patinas can provide a
protective covering to materials that would otherwise be damaged by
corrosion or weathering. They may also be aesthetically appealing.
On metal, patina is a coating of various chemical compounds such as oxides, carbonates, sulfides, or sulfates formed on the surface during exposure to atmospheric elements (oxygen, rain, acid rain, carbon dioxide, sulfur-bearing
compounds), a common example of which is rust which forms on iron or
steel when exposed to oxygen. Patina also refers to accumulated changes
in surface texture and colour that result from normal use of an object
such as a coin or a piece of furniture over time.

Graphene layer could quadruple rate of condensation heat transfer in generating plants
Jun 01, 2015
Most
of the world's electricity-producing power plants—whether powered by
coal, natural gas, or nuclear fission—make electricity by generating
steam that turns a turbine. That steam then is condensed back to water,
and the cycle begins again.
But the condensers that
collect the steam are quite inefficient, and improving them could make a
big difference in overall power plant efficiency.
Now,
a team of researchers at MIT has developed a way of coating these
condenser surfaces with a layer of graphene, just one atom thick, and
found that this can improve the rate of heat transfer by a factor of
four—and potentially even more than that, with further work. And unlike
polymer coatings, the graphene coatings have proven to be highly durable
in laboratory tests.

Hexavalent chromium compounds are a key ingredient in coatings used to rust-proof steel. They also happen to be carcinogenic. Researchers, therefore, have been looking for non-toxic alternatives that could be used to keep steel items from corroding.

Slick coating keeps steel clean and tough
October 21, 2015
When liquids stick to steel for long enough, the steel corrodes or
becomes contaminated. Unfortunately, however, porous surface coatings
that repel liquids also tend to make steel weaker … until now, that is.
Scientists at Harvard University have recently discovered that their
existing SLIPS (Slippery Liquid Porous Surfaces) technology not only causes liquids to roll right off, but it actually makes steel stronger.
Led by Prof. Joanna Aizenberg, the Harvard team
utilized electrochemical deposition to apply a a surface coating of
rough nanoporous tungsten oxide to small sheets of steel. This coating
took the form of an utra-thin film, actually made up of hundreds of
thousands of separate microscopic tungsten oxide "islands." The
resulting surace roughness keeps liquid from sticking to the steel.
Additionally, because they're not connected to one
another, if any of the islands are damaged by abrasion to the film, that
damage stays localized instead of affecting the whole coating.

Tin-based stanene could conduct electricity with 100 percent efficiency
December 1, 2013
A team of theoretical physicists from the US Department of Energy’s
(DOE) SLAC National Accelerator Laboratory and Stanford University is
predicting that stanene, a single layer of tin atoms laid out in a
two-dimensional structure, could conduct electricity with one hundred
percent efficiency at room temperature. If the findings are confirmed
they could pave the way for building computer chips that are faster,
consume less power, and won't heat up nearly as much.
Stanene is an example of a topological insulator,
a class of materials that conduct electricity only on their outside
edges or surfaces. When topological insulators are just one atom thick,
their edges conduct electricity with 100 percent efficiency, forcing
electrons to move in defined lanes, without resistance.

Transparent ceramics
Nanomaterials
It has been shown fairly recently that laser elements (amplifiers,

nanomaterials—produced by the low temperature sintering of high purity
nanoparticles and powders—can be produced at a relatively low cost.
These components are free of internal stress or intrinsic birefringence,

New nanowire structure absorbs light efficiently
Feb 25, 2015
Researchers
at Aalto University have developed a new method to implement different
types of nanowires side-by-side into a single array on a single
substrate. The new technique makes it possible to use different
semiconductor materials for the different types of nanowires.
'We
have succeeded in combining nanowires grown by the VLS
(vapor-liquid-solid) and SAE (selective-area epitaxy) techniques onto
the same platform. The difference compared with studies conducted
previously on the same topic is that in the dual-type array the
different materials do not grow in the same nanowire, but rather as
separate wires on the same substrate', says Docent Teppo Huhtio.
The research results were published in the Nano Letters journal on 5 February 2015.
The
new fabrication process has many phases. First, gold nanoparticles are
spread on a substrate. Next, the substrate is coated with silicon oxide,
into which small holes are then patterned using electron beam
lithography. In the first step of growth, (SAE), nanowires grow from
where the holes are located, after which the silicon oxide is removed.
In the second phase different types of nanowires are grown with the help
of the gold nanoparticles (VLS). The researchers used metalorganic
vapor phase epitaxy reactor in which the starting materials decompose at
a high temperature, forming semiconductor compounds on the substrate.
'In this way we managed to combine two growth methods into the same process', says doctoral candidate Joona-Pekko Kakko.
'We
noticed in optical reflection measurements that light couples better to
this kind of combination structure. For instance, a solar cell has less
reflection and better absorption of light', Huhtio adds.
In
addition to solar cells and LEDs, the researchers also see good
applications in thermoelectric generators. Further processing for
component applications has already begun.
Nanowires are
being intensely researched, because semiconductor components that are
currently in use need to be made smaller and more cost-effective. The
nanowires made out of semiconductor materials are typically 1-10
micrometres in length, with diameters of 5-100 nanometres.

Quantum scientists break aluminium 'monopoly' (Update)
May 25, 2015
A Majorana fermion, or a Majorana particle, is a fermion that is its own antiparticle. Discovering the Majorana was the first step, but utilizing it as a quantum bit (qubit) still remains a major challenge. An important step towards this goal has just been taken by researchers from TU Delft in today's issue of Nature Physics. It is a nearly thirty-year-old scientific problem that has just been resolved: demonstrating the difference between the even and odd occupation of a superconductor in high magnetic fields. Thus far, this was only possible in aluminium, which is incompatible with Majoranas. This result enables the read out and manipulation of quantum states encoded in prospective Majorana qubits.

If

parts pearls (potassium phosphate), 54 parts feldspar (most likely

parts kryolite (sodium fluoraluminate),-actually used as a stomach
insecticide as the crystals punch holes in insect gut cells!), 5 parts
arsenic, and 7 oz. of copper scales (for the blue color). As you can
tell from this formula, there's a lot more lead and fluoride than
arsenic in the batch and the dust during the mixing of the batch would
be quite dangerous. However, once fused in the melting process, none of
these chemicals would be chemically active. If they were, all of our

Atomic fractals in metallic glasses
September 21, 2015
Metallic glasses are very strong and elastic materials that appear with the naked eye to be identical to stainless steel. But metallic glasses differ from ordinary metals in that they are amorphous, lacking an orderly, crystalline atomic arrangement. This random distribution of atoms, which is the primary characteristic of all glass materials (such as windowpanes and tableware), gives metallic glasses unique mechanical properties but unpredictable internal structure. Researchers in the Caltech lab of Julia Greer, professor of materials science and mechanics in the Division of Engineering and Applied Science, have shown that metallic glasses do have an atomic-level structure—if you zoom in closely enough—although it differs from the periodic lattices that characterize crystalline metals.

Improving bulk metallic glass by maximizing surface
December 22, 2015
Yale University researchers have figured out a way to refine bulk metallic glasses to improve their electrochemical performance.
Results of the research, based in the lab of chemical and environmental engineering professor André D. Taylor, are published in the Dec. 21 issue of Advanced Materials.
Bulk metallic glass (BMG), also known as amorphous metal alloy, exhibits superior mechanical properties and great formability under low temperature compared with general alloys. Numerous efforts have been applied to develop these materials for biomedical devices, high efficiency transformers, and for products that require high-strength materials, such as golf clubs.
Working with the lab of Yale professor Jan Schroers, Taylor pioneered the use of BMGs as catalysts in fuel cells. BMGs have the strength of metal, but can be shaped like a plastic, so they can be used to form nanowires and achieve high-surface areas. Increasing surface area leads to an increased performance in current density, because all of the electrochemical reactions are on the surface.

Microscopic animals inspire innovative glass research

Prof.
Juan de Pablo's 20-year exploration of the unusual properties of glass
began, oddly enough, with the microscopic animals known as water bears.
The
creatures, which go by the more formal name of tardigrades, have a
remarkable ability to withstand extreme environments of hot and cold,
and even the vacuum of space. When de Pablo read about what happens when
scientists dry out tardigrades, then revive them with water years
later, his interest was piqued.
"When you remove the
water, they very quickly coat themselves in large amounts of glassy
molecules," says de Pablo, the Liew Family Professor in Molecular
Engineering at the University of Chicago. "That's how they stay in this
state of suspended animation."
His passion to
understand how glass forms in such exotic settings helped lead de Pablo
and his fellow researchers to the unexpected discovery of a new type of
glass.

copied the structure of nacre to create a ceramic material that's almost
10 times stronger than conventional ceramics.
Natural nacre consists of layers of microscopic
tablet-like blocks, that have wavy edges not unlike jig-saw puzzle
pieces. This means that when the material is subjected to mechanical
stress, any cracks that start to form in the boundary lines between the
tablets have to follow a very circuitous route. As a result, all but the
largest cracks simply just peter out.
Scientists at Montreal's McGill University recently created super-strong glass,
by etching nacre boundary line-like cracks in glass microscope slides.
The CNRS team, however, took a different approach with the ceramic.
They started with a ceramic powder, made up of
microscopic alumina platelets. That powder was suspended in water, and
the resulting solution was then frozen. The ice crystallization process
caused the platelets to self-assemble into stacks, the boundaries
between which were similar to the wavy boundaries between nacre tablets.
A high-temperature process was then used to increase the density of the
material, thus removing the water.
In lab tests of the resulting ceramic, it was found
that cracks had great difficulty spreading through it – as is the case
with real nacre.
Additionally, the scientists state that the process
should work with any type of ceramic powder (not just alumina), and it
should be easy to scale up to industrial production levels. Besides
simply making existing types of ceramic items stronger, the technology
could also allow them to stay at the same strength, but be made much
smaller.

New kind of smart-glass changes color and produces electricity
April 9, 2015
Many types of smart-glass
have been created, some that display a tint when it gets sunny out,
others that change to prevent heat from coming in, etc. In this new
effort, the researchers sought to add something new—production of
electricity. Realizing that many types of glass are subjected to rain
and wind, they sought to find a way to coat a window that would take
advantage of triboelectrics—capturing the energy in static electricity
that occurs when two materials meet.

Vanadium dioxide 'smart glass' can be activated to block infrared light while remaining transparent to visible light
Nov 29, 2013
'Smart
glass' can switch from transparent to opaque at the flick of a switch
and is increasingly used in cars, aircraft and homes to reduce the Sun's
glare and filter out infrared light and heat. Masaki Nakano and
colleagues from the RIKEN Center for Emergent Matter Science have now
used vanadium dioxide to make a transparent material that can be
activated to block infrared light without affecting its transparency for
visible light.
Vanadium dioxide is a
well-known thermochromic material that is transparent below about 30 °C
and reflects infrared light above 60 °C. This transition is related to a
change in crystal structure that also results in a shift from
electrically insulating properties at lower temperatures to conductive
properties at higher temperatures.

Ultrathin metasurface lenses do things conventional optics can't
September 8, 2015
http://www.gizmag.com/ultrathin-metamaterial-lens-jpl-caltech/39298/?li_source=LI&li_medium=default-widget
Once, the only way to manipulate light was with the use of a transparent
glass or plastic lens whose shape and makeup determined such things as
focus,
magnification, and polarity. However, to incorporate all of these properties in
the one optical system required a large and complex collection of multiple
lenses to achieve. Now researchers working at NASA's Jet
Propulsion Laboratory (JPL) and the California Institute of Technology
(Caltech) have created a flat silicon metamaterial lens
that manages all of these thing in a microminiaure device that
electromagnetically controls the properties of any light passing it.
Using an arrangement of silicon nanopillars organized into a honeycomb pattern to form a
"metasurface" able to control the direction and attributes of light
waves, the new device may one day be mass-produced using much the same methods employed to create computer chips today.
As such, the researchers believe that applications
for their creation may include cutting-edge microscopes, displays,
sensors, and cameras that could all take advantage of the superior
characteristics of high-quality lenses at a fraction of the price.

Processing technology to improve the electrical properties of glass ceramic circuit boards
July 8, 2015
As
you ease your foot off the accelerator, a radar sensor detects how far
away you are from the other cars and intelligently adjusts your speed
appropriately. Technology like this is already helping to improve road
safety and is set to become even more commonplace. From an electrical
engineering perspective, manufacturing sensors of this kind is an
extremely tricky process: the sensors have to be able to operate at very
high frequencies but still need to be precise and efficient. TU Wien
has now managed to develop a new processing technology for the
high-precision nanostructuring of glass ceramic circuit boards. This
means that the material properties can be adjusted, thereby
significantly improving the electromagnetic behaviour of the sensor.

Space-Age Materials, One Atomic Layer at a Time
08.10.12
http://www.nasa.gov/topics/technology/features/atomic-layer_prt.htm
A
technologist at NASA's Goddard Space Flight Center in Greenbelt, Md.,
however, is experimenting with an emerging technology that might provide
another, perhaps more effective, technique for defending sensitive
spacecraft components from the high-velocity bombardments.
Vivek
Dwivedi and his collaborator, chemical engineering professor Raymond
Adomaitis from the University of Maryland, College Park, are using
atomic layer deposition (ALD) — a rapidly evolving technology for
coating plastics, semiconductors, glass, Teflon, and a plethora of other
materials — to create a new super-strong, ultra-thin coating made of
tiny tubes of boron nitride, similar in appearance to the bristles on a
toothbrush.
''Crystalline boron nitride is one of the
hardest materials in the world,'' Dwivedi said, making it ideal as a
coating to make sensitive spacecraft component less susceptible to
damage when struck by space dust, tiny rocks, and high-energy solar
particles.
Atomic Layer Deposition
The
ALD technique, which the semiconductor industry has adopted in its
manufacturing of computer chips, involves placing a substrate material
inside a reactor chamber and sequentially pulsing different types of
precursor gases to create an ultrathin film whose layers are literally
no thicker than a single atom.
ALD differs from other
techniques for applying thin films because the process is split into two
half reactions, is run in sequence, and is repeated for each layer. As a
result, technicians can accurately control the thickness and
composition of the deposited films, even deep inside pores and cavities.
This gives ALD a unique ability to coat in and around 3-D objects. This
advantage — coupled with the fact that technologists can create films
at much lower temperatures than with the other techniques — has led many
in the optics, electronics, energy, textile, and biomedical-device
fields to replace older deposition techniques with ALD.
According
to Dwivedi, if technicians use ALD to coat glass with aluminum oxide,
for example, they can strengthen glass by more than 80 percent. The
resulting thin films act like ''nano putty,'' filling the
nanometer-scale defects found in glass — the very same tiny cracks that
cause glass to break when struck by an object. ''This ALD application
has profound possibilities for the next-generation crew modules,''
Dwivedi said. ''We could decrease the thickness of the glass windows
without sacrificing strength.''

Organic fabric dyes: Safe eco-friendly alternatives for synthetic dyes
2023
Turmeric
Turmeric
is one of the oldest natural dyes used on fabric and it yields a bright
golden-yellow color. The coloring ingredient present in turmeric is
called curcumin and it is the root of the turmeric plant that is used
for dying. The roots are crushed and reduced to a powdery form before
they are boiled in hot water to form the dye. Fabrics like cotton, silk,
and wool can be dyed using this organic plant-based dye but it requires
to be combined with a mordant for a lasting effect.
Henna
Henna
is a natural dye with varied applications. The earliest usage of henna
can be traced back to Egypt about 9000 years ago. Not only is henna used
to dye clothes but it is also popularly used as a dye for human hair
and skin, which goes to show it is highly safe for dyeing clothes for
people of all ages. The dye is derived by drying and crushing the leaves
of the henna plant, and the resultant colors might range from mustard
yellow to brown. Henna can be a good alternative to synthetic disperse
dyes because it works great on polyester and nylon. It can also be used
on silk or wool when aiming for a light shade of brown.
Indigo
For
centuries, indigo has been commercially produced for dyeing fabrics in
different parts of the world and especially in Asia. The dye is
extracted from the seeds of indigo plants and the color that it produces
is royal blue. The plants are first soaked into water for fermentation
and once the hydrolysis of glucoside is over, the plant residues are
removed from the liquid. The solution is then aerated to convert the
indoxyl to indigotin, which eventually become the precipitate. Indigo
works well with natural cellulose fibers present in cotton, viscose, and
linen but can also be used to dye wool or synthetic fibers.
Cochineal
Cochineal
is a dye derived from a scaled insect bearing the same name which
contains a natural colorant called carmine in its body. It can be used
as an organic dye for fibers such as silk, cotton, and wool to obtain
colors like crimson or shades of pink. When iron, copper, or chromium
are used as mordants, more shades in the range of purple to gray can be
derived using the dye.
Malachite
Malachite is an organic
compound used to dye silk, wool, and leather. Even though it is named
after the mineral malachite owing to its color, it is not derived from
it. It is an organic chloride salt and the color it produces it a dark
shade of blue-green. This, like all the others mentioned above, is a
safer alternative for the chemical dyes which pollute water bodies and
cause harmful impact on people who work with them.

New dyeing method could help jeans shrink toxic problem
February 27, 2024
Can
the multi-billion-dollar denim industry keep producing blue jeans in
every shape, size and silhouette, while shrinking oversized levels of
hazardous pollution? Research published Tuesday suggests a new dye could
be a step in the right direction.
Scientists have been searching
for ways to make a more sustainable form of indigo, used for centuries
to color textiles, but which in its modern synthetic form needs toxic
chemicals, large quantities of water and is linked to substantial carbon
dioxide emissions.
But a study published in the journal Nature Communications suggests ditching the classic dye altogether.
Using
Indican—a colorless compound also derived form indigo-producing
plants—could reduce the environmental and societal impacts associated
with dying jeans by around 90 percent because it does not need toxic
chemicals, researchers said.

Recent advances in fungal xenobiotic metabolism: enzymes and applications
2023 Sep 2
Abstract
Fungi
have been extensively studied for their capacity to biotransform a wide
range of natural and xenobiotic compounds. This versatility is a
reflection of the broad substrate specificity of fungal enzymes such as
laccases, peroxidases and cytochromes P450, which are involved in these
reactions. This review gives an account of recent advances in the
understanding of fungal metabolism of drugs and pollutants such as dyes,
agrochemicals and per- and poly-fluorinated alkyl substances (PFAS),
and describes the key enzymes involved in xenobiotic biotransformation.
The potential of fungi and their enzymes in the bioremediation of
polluted environments and in the biocatalytic production of important
compounds is also discussed.

Researchers develop better way to make painkiller from trees
April 8, 2024
Scientists at the University of Wisconsin–Madison have developed a cost-effective and environmentally sustainable way to make a popular pain reliever and other valuable products from plants instead of petroleum.
Building on a previously patented method for producing paracetamol—the active ingredient in Tylenol—the discovery promises a greener path to one of the world's most widely used medicines and other chemicals. More importantly, it could provide new revenue streams to make cellulosic biofuels—derived from non-food plant fibers—cost competitive with fossil fuels, the primary driver of climate change.

Transposable elements study reveals potential methods to stop aging
September 25, 2023
Researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University, Hungary have made an exciting breakthrough in understanding how we age. They focused on "transposable elements" (TEs), which are parts of DNA that can move around in our genetic code. When these TEs move too much, they destabilize the genetic code and that can be the reason of aging.

Sustainable Surfboards: Everything You Ever Wanted to Know
Jan 16th, 2019
Eco-friendly materials are making our surfboards weirder, but in the best way possible.
Envirofoam
Made
by California company Marko Foam, Envirofoam is 100% recycled EPS. They
take the scraps from standard EPS blanks, as well as styrofoam and
other recyclable foams, reprocess and mix it with virgin EPS foam.
Currently, the recycled foam is mixed in with standard EPS at a ratio of
1:4 to create Marko’s Envirofoam blanks. Channel Islands currently
offers many custom shapes with the option of using a Marko Foam blank,
for an additional $125, which is the same price increase as getting a CI
board made with standard EPS. Other shapers using Envirofoam blanks
include E-Tech and Aquatic Oddities.
Myco Foam
Mushroom-based
foam made by Green Island, NY-based biomaterials company, Evocative.
Myco Foam utilizes Mycelium (the vegetative growth phase of a mushroom)
and agricultural waste. Mycelium, the root-like structure of mushrooms,
bonds the moldable material together and gets its strength from Chitin,
the same thing found in crabs’ exoskeletons. The mold hardens in about
four days. A few blanks and hand-planes have been made using Myco Foam
by Evocative, but there’s no word on how it holds up over time — or the
level of performance or durability of the mushroom-based surfboards. It
is extremely difficult to shape, so the molds have to be as close to a
finished surfboard as possible.
Algae-Based Bio-Foam
A
PU-style expandable foam made with oil converted from natural plant
materials like algae. Arctic Foam, the largest polyurethane blank
manufacturer in North America, teamed up with a group of biologists and
chemists at UCSD to find a way to turn algae oil into an expandable foam
that looks, shapes and rides like a standard PU foam surfboard.
Numerous pros like Rob Machado and Ryan Burch are riding these boards,
and by all reports, they work really well.
Super-Sap Resin
A
thermoset epoxy resin made by Entropy, a California-based chemical
company. Created by replacing petroleum-based carbon in traditional
epoxy resins with plant-based carbon. While it’s not 100% plant-based
(the highest bio content resin contains around 30% plant-based
materials), it’s suitable for all types of epoxy surfboards and releases
50% less greenhouse gases during production compared to conventional
epoxies.
Wood Veneers and Plank Overlays
Bamboo,
paulownia, albiza and balsa woods are used in a variety of different
ways during the surfboard construction process. Thin veneers are
vacuum-formed to create the board’s protective skin. Perimeter stringer
systems surround the blanks and thin planks are laid over the foam
cores. Shapers like Danny Hess in San Francisco, Gary Young in Hawaii
and Timberline Surfboards out of Santa Barbara all use some variation of
these processes. Which equates to using less fiberglass and resin and a
longer-lasting, more durable surfboard. They also look beautiful. And
while generally quite a bit heavier than standard foam and fiberglass
boards, they ride well, especially in solid, powerful surf. The downside
is their expense. They cost anywhere from silly expensive to stupid
expensive.
Hemp Cloth Skins
There are a couple emerging
alternatives to fiberglass cloth. The most promising is a woven hemp
cloth: 100% biodegradable and non-toxic with similar properties and flex
patters to fiberglass. The yellowish tint can be an issue, and the jury
is still out on how a hemp-glassed board holds up over time — and in
heavy, board-breaking surf.
Alternative Cores
Agave Cactus
Recently
bursting onto the scene with a highly publicized board shaped by Gary
Linden and sponsored by tequila giant Jose Cuervo. Agave cactus blooms
at the end of its life cycle, and a tall, treelike stalk sprouts from
the center of the plant. These agave stalks are harvested, dried, glued
together and finally shaped in a similar fashion to a balsa wood board.
Appealing, because even the fins can be made using the agave plant, so a
100% plant-based surfboard that’s lighter than traditional wood is
indeed a possibility. Agave is extremely difficult to shape with, so
only a few master shapers even take the challenge on. It also takes a
long time to dry, so each board takes around three months start to
finish.
Wood
The original Hawaiian surfboards were all
made of wood and a few board manufacturers still use wood for their
cores. Some, like Driftwood Surfboards, utilize hollow wood cores to
keep the weight down, while Grain Surfboards uses a variety of local
sustainable softwoods. Both companies offer surfers a chance to build
their own board through numerous workshop classes. Sustainable and
beautiful, the wood boards are also pretty expensive (a custom board
from Grain will run you around 2K), and the extra weight can inhibit
performance at the highest levels of surfing.

7 Green Leaf Alternatives for Food Packaging as Lagos State Bans Styrofoam
January 24, 2024
A Case for green leaf packaging
Leaves
are an age-long alternative for packaging food, but most restaurants
restrict leaf packaging to local recipes such as ofada rice and moi-moi,
when there’s nothing stopping them from extending it to other meals on
the menu.
Why are they better than plastics?
Leaves degrade quickly after use
They are organic, so they contain no artificial chemicals that can pollute the environment
Leaves are raw materials that do not need production processes that pollute the environment, unlike synthetic packaging
Also, the leaf packaging options for food service providers are endless. We checked and found seven.
Moi-moi leaves
Banana leaves
Plantain leaves
Coco yam leaves

The Pros and Cons of Silicone Cookware
Oct 10, 2019
https://ceh.org/yourhealth/pros-cons-silicone/
Five Reasons to Love Silicone
Heat stable: Silicone can usually be used up to temperatures of 400(F)
and can withstand going from extreme heat to extreme cold (2). This
makes it a kid-friendly option, but is also great for busy adults who
love to cook and leftovers freeze easily in silicone dishware. And when
you’re done, the silicone dishware can just be tossed into the
dishwasher without any fear of it coming out melted after a high heat
wash (2).
Flexible: Smash it, drop it, squeeze it, silicone will survive basically anything (except maybe an apocalypse) (2).
Degrades into large pieces: Believe it or not, this is actually a good
thing! Because silicone products degrade into larger pieces, they are
not as readily ingested by marine life, animal life and consequently, by
humans as well (4)!
Durable: Compared to plastic that can crack,
or glass that can shatter, silicone products are a great alternative
that last basically forever (hurrah for our budgets!) (2).
Healthier than Traditional Non-stick: Non-stick baking pans contain
perfluorinated chemicals (PFAS) which although great at being nonstick,
are not great for the planet or for humans health.
Five Reasons to be Wary of Silicone
Unknown long-term safety: Silicone products are fairly new to the
market. Therefore, there have been very few studies conducted on the
safety of silicone products and even fewer on the long-term health
effects of using silicone products (6).
Chemical fillers:
Depending on the quality of the silicone product, it may or may not
contain chemical fillers (2,4). Generally, the higher the quality of
silicone, the less likely it will contain chemical fillers (4).
Migration of chemicals into food: Studies have found chemicals in
silicone products passing from storage containers, cookware and nursing
teats (3,5).
Migration of chemicals into air: When silicone
products are exposed to high temperatures (think baking), the chemicals
in the product can be released into the air (2). The released particles
tend to persist in the air and pose a health hazard to the lungs (2).
Special recycling process: In order for silicone to be down-cycled, you
will need to bring products to special recycling centers (4).

Europe’s current position in producing bio-based polymers is limited to a
few polymers. However, new developments and investments are foreseen:
the first European industrial-scale PLA plant by 2014, the introduction
of PET production facilities by 2015, recent developments in the
commercialization of bio-based PBT and further advancements in the field
of high-value fine chemicals for PA, PUR and thermosets production.
Although Europe shows a strong demand for bio-based polymers, production
tends to take place elsewhere-largely the consequence of an

Cellulose-Based Bio- and Nanocomposites: A Review
http://www.hindawi.com/journals/ijps/2011/837875/
Cellulose macro- and nanofibers have gained increasing attention due to the high
strength and stiffness, biodegradability and renewability, and their production and
application
in development of composites. Application of cellulose nanofibers for
the development of composites is a relatively new research area.
Cellulose macro- and nanofibers can be used as reinforcement in
composite materials because of enhanced mechanical, thermal, and
biodegradation properties of composites. Cellulose fibers are
hydrophilic in nature, so it becomes necessary to increase their surface
roughness for the development of composites with enhanced properties.
In the present paper, we have reviewed the surface modification of
cellulose fibers by various methods. Processing methods, properties, and
various applications of nanocellulose and cellulosic composites are
also discussed in this paper.

ARCHIVED - Lighter, Stronger, "Greener" Plastics
For
several years, the NRC-IMI team has been perfecting techniques
involving the use of clay nanoparticles to create new nanocomposite
plastics. Nanocomposites have been proven to dramatically increase the
strength of polymer materials. Just last year, NRC-IMI launched a joint
industry partnership group focused on nanocomposites to further explore
the use of such materials. It is hoped that nanoclays will add critical
strength to already lightweight foamed materials. As well, nanoparticles
have been shown to enhance the growth of foam cells, a process known as
nucleation. In the past year, a NRC-ICPET research team, in
collaboration with University of Ottawa, became the second group in the
world to publish results on the fundamental interaction of CO2 with
nanocomposites - an emerging area of study.

A green and efficient method for preparing acetylated cassava stillage residue and the production of all-plant fibre composites
2014
Cassava stillage residue (CSR), a kind of agro-industrial plant fibres,
was directly acetylated and converted into thermoplastic material by
mechanical activation-assisted solid phase reaction (MASPR) in a
stirring ball mill without the use of organic solvent and additives. As
combining mechanical activation and chemical modification in the same
equipment, the destruction of hydrogen bonds and crystalline structure
of CSR induced by intense milling improved the reactivity of CSR,
leading to the effective acetylation of CSR. After acetylation by MASPR,
the modified CSRs possessed thermoplasticity, ascribing to the
introduction of acetyl groups and the destruction of high crystallinity
structure of cellulose. The self-reinforced all-plant fibre composites
(APFC) were successfully produced with the modified CSRs as both matrix
and reinforcement by hot pressing technology. The direct acetylation of
CSR and successful production of APFC suggested that MASPR was a simple,
efficient and environmentally friendly method for chemical modification
of agro-industrial lignocellulose biomass.

Progress in bio-based plastics and plasticizing modifications
2013
Over the coming few decades bioplastic materials are expected to
complement and gradually replace some of the fossil oil based materials.
Multidisciplinary research efforts have generated a significant level
of technical and commercial success towards these bio-based materials.
However, extensive application of these bio-based plastics is still
challenged by one or more of their possible inherent limitations, such
as poor processability, brittleness, hydrophilicity, poor moisture and
gas barrier, inferior compatibility, poor electrical, thermal and
physical properties. The incorporation of additives such as plasticizers
into the biopolymers is a common practice to improve these inherent
limitations. Generally, plasticizers are added to both synthetic and
bio-based polymeric materials to impart flexibility, improve toughness,
and lower the glass transition temperature. This review introduces the
most common bio-based plastics and provides an overview of recent
advances in the selection and use of plasticizers, and their effect on
the performance of these materials. In addition to plasticizers, we also
present a perspective of other emerging techniques of improving the
overall performance of bio-based plastics. Although a wide variety of
bio-based plastics are under development, this review focuses on
plasticizers utilized for the most extensively studied bioplastics
including poly(lactic acid), polyhydroxyalkanoates, thermoplastic
starch, proteinaceous plastics and cellulose acetates. The ongoing
challenge and future potentials of plasticizers for bio-based plastics
are also discussed.

Effect of biodegradable plasticizers on thermal and mechanical properties of poly(3-hydroxybutyrate)
2004
The effects of biodegradable plasticizers on the thermal and mechanical
properties of poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were
studied using thermal and mechanical analyses. Soybean oil (SO),
epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl
citrate (TEC) were used as plasticizing additives. PHBV/plasticizer
blends were prepared by evaporating solvent from blend solutions. The
content of plasticizer in the blends was kept at 20wt%. Compatibility of
plasticizer with PHBV was examined with differential scanning
calorimetry (DSC) and scanning electron microscopy (SEM). DPB and TEC
were more effective than soybean oils (SO and ESO) in depression of the
glass transition temperatures as well as in increasing the elongation at
break and the impact strength of the films. From the thermal and
mechanical properties of the plasticized PHBV, it could be concluded
that TEC or DBP are better plasticizers than SO and ESO for PHBV.

IBM discovers first new class of polymers in decades
May 15, 2014
http://www.gizmag.com/ibm-polymer-discovery-plastic/32088/?li_source=LI&li_medium=default-widget
The IBM polymers consist of two related classes of plastic materials. They’re formed by combining paraformaldehyde and 4,4ʹ-oxydianiline in what’s called a condensation reaction. When heated to 250⁰ C (482⁰ F) the material becomes very strong as covalent bonds form and the solvent is forced out, forming the first of two versions of the polymer. Both versions are highly elastic, resistant to solvents, and are recyclable. One version can even self-heal.
These polymers also show new physical properties. The first version is lightweight, stiff, resistant to cracking, shows more strength than bone, and can also turned into new polymer structures with half again as much strength. However, it is very brittle, like glass. When mixed with carbon nanofibers and heated, it forms an extremely strong, lightweight composite material that is similar to metal, yet has a degree of self-healing when cracked.

Characteristics of biodegradable polylactide/gelatinized starch films: Effects of starch, plasticizer, and compatibilizer
2012
Polylactide (PLA) blends with 0–40 wt % gelatinized starches (GSs) in
the presence of plasticizers and compatibilizer for improving
interfacial bonding between two phases were prepared. The effects of
compatibilizer, type and amount of starch, including type and
concentration of plasticizer on the physical, morphological, thermal,
and mechanical properties of these films were investigated. Two types of
starch (corn and tapioca) were added as fillers, whereas the glycerol
amount was varied from 0 to 35 wt % based on starch content.
Polyethylene glycol (PEG400) and propylene glycol (PG) were added as
plasticizers at four different amounts (5–20 wt %) based on PLA content,
while methylenediphenyl diisocyanate was used as a compatibilizer at
1.25 wt % of GS. The results indicated that the presence of glycerol had
no effect on the thermal degradation of GS. For PLA plasticization, the
plasticized PLA with PEG400 had better properties than that with PG.
Water absorption isotherm of the blend films increased as the amount of
starches increased; in contrast, the tensile properties decreased
progressively with the addition of the GS content. The blend films with
gelatinized corn starch had higher tensile properties than those with
gelatinized tapioca starch.

Porous Biodegradable Starch-Based Polymer: Effects of Plasticizers on the Physical Properties
2014
The effect of the plasticizer content (mixture of water and glycerol) on
the cellular structure of the considered material and its influence on
the resulting properties, such as mechanical stiffness, are investigated
by means of optical microscopy, X-ray diffraction, thermogravimetry and
standard mechanical testing. Adding glycerol leads to larger cell walls
and smaller pores but it does not significantly affect the elastic
tangent modulus and strength under compression for deformations up to
50%; only a tendency to promote elastic recovery is observed.

Plastic is not inert
Conventional plastic contains a large number, and sometimes a large
proportion, of chemical additives which can be endocrine disruptors,
carcinogenic or provoke other toxic reactions and can, in principle,
migrate into the environment, though in small quantities. Persistent
organic pollutants (POPs), such as pesticides like DDT and
polychlorinated biphenyls (PCBs), can attach themselves from the
surrounding water to plastic fragments which can be harmful and enter
the food chain via marine fauna.

Sensor detects toxins leaching from plastic
December 10, 2015
Dr Asif Zia, together with Professor Subhas Mukhopadhyay, both from the School Engineering and Advanced Technology developed an electrochemical sensing system that is able to rapidly quantify a synthetic compound – di(2-ethylhexyl)phthalate or DEHP for short.
DEHP is used to induce flexibility in the plastic products but, because of its molecular structure, it does not attach itself covalently to the plastic's lattice structure and may leach into the surrounding environment. It is classed as a teratogenic, or malformation causing, compound as well as an endocrine-disrupter, which interferes with the body's natural hormonal system. The World Health Organization refers concentrations of DEHP greater than six parts per billion as hazardous for human health.

Company unlocks secret to making plastic out of air
July 30, 2014
"We're not the first people to have the idea of turning greenhouse
gas into plastic," Herrera said. "The thing that was missing was that no
one had figured out how to do it cost-effectively."
Here's how
it works: Carbon emissions are captured from farms, landfills, and
energy facilities and are fed into a 50-foot-tall reactor at Newlight's
plant. A bundle of enzymes strips out the carbon and oxygen and
rearranges them into a substance they call air carbon.
The product is then melted down and cooled inside tubes and sliced into little plastic pellets that can be molded into anything.
Herrema calls it "a disruptive technology that's gonna change the world."

New catalyst paves way for bio-based plastics, chemicals

Washington
State University researchers have developed a catalyst that easily
converts bio-based ethanol to a widely used industrial chemical, paving
the way for more environmentally friendly, bio-based plastics and
products.
The researchers have published a paper online
describing the catalyst in the Journal of the American Chemical Society
and have been granted a U.S. patent.
The chemical
industry is interested in moving away from fossil fuels to bio-based
products to reduce environmental impacts and to meet new regulations for
sustainability, said Yong Wang, Voiland Distinguished Professor in the
Gene and Linda Voiland School of Chemical Engineering and
Bioengineering.
The catalyst works on bio-based ethanol to create isobutene used in plastics and other products.
The
industry has traditionally made a widely used chemical called isobutene
- used in everything from plastic soda bottles to rubber tires - by
superheating crude oil. But in collaboration with the Archer Daniels
Midland (ADM) Company, Wang and his colleagues developed a catalyst to
convert bio-based ethanol, which is made from corn or other biomass, to
isobutene in one easy production step.

Cheap, biodegradable, biocompatible "Shrilk" is a potential plastic replacement
December 14, 2011
Web-slinging arachnids already have researchers toiling away looking to replicate the remarkable properties of spider silk.
Now spiders, along with their insect and crustacean arthropod cousins,
have provided inspiration for a new material that is cheap to produce,
biodegradable, and biocompatible. Its creators say the material, dubbed
"Shrilk," has the potential to replace plastics in consumer products and
could also be used safely in a variety of medical applications, such as
suturing wounds or serving as scaffolding for tissue regeneration.
Arthropods have an outer skeleton made up of a
composite material called cuticle that consists of layers of a
polysaccharide polymer called chitin and protein organized in a laminar,
plywood-like structure. In its unmodified form, which can be seen in
the body wall of a caterpillar, chitin is translucent, pliable,
resilient and quite tough, but arthropods are able to modify its
properties to make it tough and rigid, as seen in the body wall of a
beetle, or to make it elastic, as seen in arthropod limb joints. Not
only does cuticle protect the arthropod's internal components and
provide structure for muscles and wings, it does so without adding
weight or bulk.

Study reveals how liquid protein droplets age into rubber ball-like elastic solids
July 12, 2024
The University at Buffalo research lab of Priya Banerjee is conducting research on liquid droplets of proteins and their role in human diseases. Their new study sheds light on why these droplets have viscoelastic properties.
Droplets of proteins, tied to an increasing number of cellular processes and human diseases, are known for their liquid-like ability to flow, exchange material and dissolve as needed.
Yet these droplets, known as biomolecular condensates, are something akin to childhood staple Silly Putty in that they can also transform into more solid-like structures.
Now, a collaborative effort between the University at Buffalo, St. Jude Children’s Research Hospital and Washington University in St. Louis has found that condensates’ unique viscoelastic properties are determined by the amino acid sequence of the proteins that form them.
The team’s study, published July 2 in Nature Physics, found that whether the condensates behave more like a viscous liquid or an elastic solid depends on the strength and duration of the amino acids’ interactions. This can explain why condensates act like molecular putty and how they can even age into a solid similar to a rubber ball.
"Shedding light on the intricate behavior of condensates at the molecular level is crucial for advancing our knowledge of cellular biology and understanding their association with many neurodegenerative diseases,” says the study’s lead corresponding author, Priya R. Banerjee, PhD, associate professor of physics in the UB College of Arts and Sciences. “This work reveals the mechanisms behind cellular processes that have long been observed but never fully understood.”

New production process makes PLA bioplastic cheaper and greener
July 21, 2015
Polylactic acid (PLA) is a biodegradable bioplastic that is already
used to produce a variety of everyday items, such as cups, trays, bowls
and vegetable wrapping foil. Unfortunately, the current PLA production
process is expensive and produces waste. Researchers at the KU Leuven
Centre for Surface Chemistry and Catalysis in Belgium have now developed
a new production technique that is cheaper and greener and makes PLA a
more attractive alternative to petroleum-based plastics.
PLA boasts a number of advantages over
petroleum-based plastic. It is one of the few plastics suitable for use
in 3D printers, it is biocompatible, making it suitable for medical use,
and it biodegrades in a few years in certain environments, and is
industrially compostable and recyclable. But when it comes to cost, PLA
can't compete with petroleum-based plastics due to the intermediary
steps required to produce it.
As its name suggests, lactic acid is a main building
block of PLA. This can be obtained by the fermentation of sugar that can
be sourced from renewable resources such as corn starch, tapioca and
sugarcane.

Surfaces are carefully measured to quantify their roughness and texture, but this can be surprisingly tricky.
The importance of a surface's roughness can be seen in car engines, where if the walls of the engine's cylinders are too smooth they will seize, meaning that the surface needs to be just rough enough to carry a film of lubricant to maintain a smooth piston action.

Plasticizer
http://en.wikipedia.org/wiki/Plasticizer
Plasticizers (UK: plasticisers) or dispersants are additives that increase the plasticity or fluidity of a material. The dominant applications are for plastics, especially polyvinyl chloride (PVC). The properties of other materials are also improved when blended with plasticizers including concrete, clays, and related products.
Effect on health
Substantial concerns have been expressed over the safety of some plasticizers, especially because several ortho-phthalates have been classified as potential endocrine disruptors with some developmental toxicity reported.
Appendix: various specific plasticizers
Dicarboxylic/tricarboxylic ester-based plasticizers
- Phthalate-based
plasticizers are used in situations where good resistance to water and
oils is required. Some common phthalate plasticizers are:
- Bis(2-ethylhexyl) phthalate (DEHP), used in construction materials and medical devices
- Diisononyl phthalate (DINP), used in flooring materials, found in garden hoses, shoes, toys, and building materials
- Di-n-butyl phthalate (DnBP, DBP), used for cellulose plastics, food wraps, adhesives, perfumes, and cosmetics - about a third of nail polishes, glosses, enamels, and hardeners contain it, together with some shampoos, sunscreens, skin emollients, and insect repellents
- Butyl benzyl phthalate (BBzP) is found in vinyl tiles, traffic cones, food conveyor belts, artificial leather, and plastic foams
- Diisodecyl phthalate (DIDP), used for insulation of wires and cables, car undercoating, shoes, carpets, pool liners
- Dioctyl phthalate (DOP or DnOP), used in flooring materials, carpets, notebook covers, and high explosives, such as Semtex. Together with DEHP it was the most common plasticizers
- Diisooctyl phthalate (DIOP), all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane.
- Diethyl phthalate (DEP)
- Diisobutyl phthalate (DIBP)

volatility.
- Trimethyl trimellitate (TMTM)
- Tri-(2-ethylhexyl) trimellitate (TEHTM-MG)
- Tri-(n-octyl,n-decyl) trimellitate (ATM)
- Tri-(heptyl,nonyl) trimellitate (LTM)
- n-octyl trimellitate (OTM)
Adipates, sebacates, maleates

A Promising Approach for Rapid Stabilization of Plastics
April 26, 2023
In a new study, scientists from the University of Cambridge have developed a novel approach to rapid stabilization of plastics, offering a potential solution to the global plastic pollution crisis. The new approach, published in the journal Nature Communications, makes use of a process called “rapid polymerization”, which allows plastic materials to be stabilized in just minutes, as opposed to the current method of stabilization, which can take several days to complete. The process also uses fewer chemicals than current methods, resulting in a greener approach to plastic stabilization. The scientists behind the new approach hope that it will help reduce the amount of plastic pollution in our oceans and environment.

from the fibers of date palms, flax, grass, papyrus, leather, or camel
hair. The use of such ropes pulled by thousands of slaves allowed the
Egyptians to move the heavy stones required to build the pyramids. By
about 2800
B.C.
, rope made of hemp fibers was in use in China.
Raw Materials
Rope may be made either from natural fibers, which have been processed to allow them to be easily formed into yarn, or from synthetic materials, which have been spun into fibers or extruded into long filaments.
Natural fibers include hemp, sisal, cotton, flax, and jute. Another
natural material is called manila hemp, but it is actually the fibers from
a banana plant. Sisal was used extensively to make twine, but synthetic
materials are replacing it. Manila rope is still used by traditionalists,
but it can rot from the inside, thus losing its strength without giving
any outward indication.
Synthetic fibers include nylon,
polyester,
polypropylene and aramid. Polypropylene costs the least, floats on water,
and does not stretch appreciably. For these reasons it makes a good water
ski tow rope. Nylon is moderately expensive, fairly strong, and has quite
a bit of stretch. It makes a good mooring and docking line for boats
because of its ability to give slightly, yet hold. Aramid is the
strongest, but is also very expensive. Nylon and polyester may be spun
into fibers about 4-10 inches (10-25 cm) long. Ropes made from spun
synthetic fibers feel fuzzy and are not as strong as ropes made from long,
continuous filaments. Some ropes use two different synthetic materials to
achieve a combination of high strength and low cost or high strength and
smooth surface finish.
Wire rope may be made from iron or steel wires. This is commonly referred
to as cable and is used in bridges,
elevators,
and cranes. It is made by a different process than fiber or filament
ropes.

Silver-Nanowire-Based Elastic Conductors: Preparation Processes and Substrate Adhesion
2023 Mar 21
Abstract
The production of flexible electronic systems includes stretchable electrical interconnections and flexible electronic components, promoting the research and development of flexible conductors and stretchable conductive materials with large bending deformation or torsion resistance. Silver nanowires have the advantages of high conductivity, good transparency and flexibility in the development of flexible electronic products. In order to further prepare system-level flexible systems (such as autonomous full-software robots, etc.), it is necessary to focus on the conductivity of the system’s composite conductor and the robustness of the system at the physical level. In terms of conductor preparation processes and substrate adhesion strategies, the more commonly used solutions are selected. Four kinds of elastic preparation processes (pretensioned/geometrically topological matrix, conductive fiber, aerogel composite, mixed percolation dopant) and five kinds of processes (coating, embedding, changing surface energy, chemical bond and force, adjusting tension and diffusion) to enhance the adhesion of composite conductors using silver nanowires as current-carrying channel substrates were reviewed. It is recommended to use the preparation process of mixed percolation doping and the adhesion mode of embedding/chemical bonding under non-special conditions. Developments in 3D printing and soft robots are also discussed.

Artificial graphene could outperform the real thing
February 14, 2014
Graphene
is truly a 21st-century wonder material, finding use in everything from
solar cells to batteries to tiny antennas. Now, however, a group of
European research institutes have joined forces to create a graphene
knock-off, that could prove to be even more versatile.
Conventional
graphene takes the form of a one-atom-thick sheet of carbon atoms,
linked together in a honeycomb pattern. Along with being transparent and
conductive, it is also both the world's thinnest material, and the
strongest.
The artificial graphene has the same
honeycomb structure, but is made from nanometer-thick semiconductor
crystals instead of carbon atoms. The chemical makeup, size and shape of
those crystals can be tweaked, essentially custom-tuning the properties
of the material to the desired application.
It could
conceivably be used in many of the same places in which graphene is
currently utilized, but with even better performance. According to
project partner the University of Luxembourg, “'Artificial graphene'
should lead to faster, smaller and lighter electronic and optical
devices of all kinds, including higher performance photovoltaic cells,
lasers or LED lighting."

With
the continued rise in the uptake of solar cells, consumers are now
looking at less obtrusive ways to incorporate these in buildings and
vehicles. Transparent or semi-transparent cells provide greater
flexibility and visual appeal than standard, opaque silicon solar cells,
however their relatively high-cost and poor efficiencies have meant
that their adoption has been slow. To help remedy this, researchers
working at the Hong Kong Polytechnic University (PolyU) have created
semi-transparent, efficient, low-cost perovskite solar cells with

Conductive graphene yarn is lighter and stretchier than copper wire
June 23, 2014
The researchers started by chemically exfoliating flakes of graphene
from a block of graphite. Those flakes were then mixed with water, and
that mixture was concentrated into a slurry using a centrifuge. That
slurry was then spread across a plate and allowed to dry, forming into a
thin transparent film of graphene oxide.
The film was subsequently peeled off the plate and
cut into narrow strips, those strips in turn getting wound together
using an automatic fiber scroller.
The resulting yarn can be knotted and stretched
without fracturing, and is said to be much stronger than other types of
carbon fibers – this quality could be due to the presence of tiny air
pockets within it.
Removing oxygen from the material boosts its
electrical conductivity, and adding silver nanorods to it in the
film-fabricating stage could reportedly boost that conductivity further,
to the point of matching that of copper. Its stretchability and lighter
weight, however, could make it a better alternative in many
applications.

While graphene is already known for being the world's strongest material, most studies have focused on its tensile strength – that's the maximum stress that it can withstand while being pulled or stretched, before failing. According to studies conducted at Houston's Rice University, however, its ability to absorb sudden impacts hadn't previously been thoroughly explored. As it turns out, the material is 10 times better than steel at dissipating kinetic energy. That could make it an excellent choice for lightweight ballistic body armor.

A new way to make higher quality bilayer graphene
February 8, 2016
A team of researchers with members from institutions in the U.S., Korea and China has developed a new way to make bilayer graphene that is higher in quality than that produced through any other known process. In their paper published in Nature Nanotechnology, the team describes the technique they developed and the possible uses for the bilayer graphene that is produced.
Graphene is, of course, a flat material made from just single carbon atoms; it forms in a honeycomb pattern and has been found to have excellent electrical properties—one hindrance to using graphene in many applications has been the lack of a bandgap. That hindrance was partially overcome back in 2009 when a team working in the U.S. found that creating two layers of graphene bonded together and then applying electricity could cause a bandgap to occur. Since that time, researchers have been looking for ways to create such bilayer graphene in a way that could be commercialized. In this latest effort, the researchers report on a new technique they have developed that they claim produces the highest quality bilayer graphene yet.

2D self-assembling semiconductor could beat out graphene
May 2, 2014
Graphene may be talked about as the future wonder material (and for
that matter, the present one), but it has one critical deficiency. It
lacks a natural bandgap, the physical trait that puts the “semi” in
“semiconductor," so it has to be doped to become effective. Enter
Ni3(2,3,6,7,10,11-hexaiminotriphenylene)2 ... well, you can refer to it
as a metal-organic graphene analogue for now. In addition to having a
natural band gap, it’s able to self-assemble and represents a whole
family of compounds that’s exciting to researchers for its novel
properties.
Nickel (the metal) and HITP (the organic compound)
are represented in the diagram at the top of the page, with nickel
colored in green, amino groups in purple, and carbon rings in grey. The
amino groups in the carbon rings are attracted to the nickel, and
because of the symmetry and geometry in HITP, the overall organometallic
complex almost has a fractal nature that allows this new semiconductor
to self-organize perfectly. A band gap is created in the “hole” where
electrons aren’t, a space that's just about 2 nm across.

World's lightest solid material, known as 'frozen smoke', gets even lighter
January 13, 2011
Researchers have created a new aerogel that boasts amazing strength
and an incredibly large surface area. Nicknamed ‘frozen smoke’ due to
its translucent appearance, aerogels are manufactured materials derived
from a gel in which the liquid component of the gel has been replaced
with a gas, resulting in a material renowned as the world’s lightest
solid material. The new so-called “multiwalled carbon nanotube (MCNT)
aerogel” could be used in sensors to detect pollutants and toxic
substances, chemical reactors, and electronics components.
Although aerogels have been fabricated from silica,
metal oxides, polymers, and carbon-based materials and are already used
in thermal insulation in windows and buildings, tennis racquets, sponges
to clean up oil spills, and other products, few scientists have
succeeded in making aerogels from carbon nanotubes.
The researchers were able to succeed where so many
before them had failed using a wet gel of well-dispersed pristine
MWCNTs. After removing the liquid component from the MWCNT wet gel, they
were able to create the lightest ever free-standing MWCNT aerogel
monolith with a density of 4 mg/cm3.
MWCNT aerogels infused with a plastic material are
flexible, like a spring that can be stretched thousands of times, and if
the nanotubes in a one-ounce cube were unraveled and placed
side-to-side and end-to-end, they would carpet three football fields.
The MWCNT aerogels are also excellent conductors of electricity, which
is what makes them ideal for sensing applications and offers great
potential for their use in electronics components.

Aerographite claims title of World's Lightest Solid Material
July 12, 2012
http://www.gizmag.com/aerographite-worlds-lightest-material/23295/?li_source=LI&li_medium=default-widget
While they were each once hailed as the lightest solid material ever made, metallic microlattice and aerogel have now been moved back to second and third place (respectively), with aerographite taking the crown. Developed by a team from the Technical University of Hamburg and Germany’s University of Kiel, the material is composed of 99.99 percent air, along with a three-dimensional network of porous carbon nanotubes that were grown into each other.
Aerographite has a density of less than 0.2 milligrams per cubic centimeter, which allows it be compressed by a factor of 1,000, then subsequently spring back to its original state. Despite its extremely low density, it is black and optically-opaque in appearance. By contrast, the density of metallic microlattice sits at 0.9 mg per cubic centimeter.
The scientists discovered the sponge-like material when they were researching three-dimensionally cross-linked carbon structures. It is reportedly much more robust than the relatively fragile aerogel, being able to withstand at least 35 times as much mechanical force for its density. It is grown in a one-step process using zinc oxide templates, which allow blocks of the material to be created in various shapes, in sizes as large as several cubic centimeters.

Graphene aerogel takes world’s lightest material crown
March 24, 2013
Not even a year after it claimed the title of the world’s lightest material, aerographite has been knocked off its crown by a new aerogel made from graphene. Created by a research team from China’s Zhejiang University in the Department of Polymer Science and Engineering lab headed by Professor Gao Chao, the ultra-light aerogel has a density lower than that of helium and just twice that of hydrogen.
Although first created in 1931 by American scientist and chemical engineer, Samuel Stephens Kistler, aerogels have recently become a hotly contested area of scientific research. A “multiwalled carbon nanotube (MCNT) aerogel” dubbed “frozen smoke” with a density of 4 mg/cm3 lost its world’s lightest material title in 2011 to a micro-lattice material with a density of 0.9 mg/cm3. Less than a year later, aerographite claimed the crown with its density of 0.18 mg/cm3.
Now a new title-holder has been crowned, with the graphene aerogel created by Gao and his team boasting a density of just 0.16 mg/cm3. To create the record-setting material, Gao and his team turned to the wonder material du jour – graphene. Building on experience in developing macroscopic graphene materials, including one-dimensional graphene fibers and two-dimensional graphene films, the team decided to add another dimension and make a three-dimensional porous material out of graphene in an attempt to claim the record.
Instead of the sol-gel method and template-oriented methods generally used to create aerogels, Gao and his team used a new freeze-drying method that involved freeze-drying solutions of carbon nanotubes and graphene to create a carbon sponge that can be arbitrarily adjusted to any shape.

Microstructured materials as strong as steel yet less dense than water
April 14, 2014
Researchers in Germany have developed a lightweight, high-strength
material inspired by the framework structure of bones and wood and the
shell structure of bees' honeycombs. Created using 3D laser polymer
printing combined with a ceramic coating, the material is less dense
than water but, relative to its size, boasts strength comparable to
high-performance steel or aluminum.
Although inspired by nature, the polymer
microarchitecture produced by a team at the Karlsruhe Institute of
Technology (KIT) outperforms its natural counterparts in terms of
strength/density ratio. The underlying structure was produced using a
process of 3D laser lithography or polymer printing and hardening.
A number of structures were tested, including
triangular, hexagonal and honeycomb. These were then coated by gas
deposition to provide extra strength, with coatings of a ceramic
material and alumina both tested. The polymer structure measured roughly
50 µm long, wide, and high, while various coating thicknesses were
tested ranging from 10 nm to 200 nm.
It was found that a honeycomb polymer structure with
an alumina coating of 50 nm yielded the highest stability to density
ratio. This microarchitecture outperformed the triangular and hexagonal
counterparts produced and tested, while no additional strength was
achieved after a coating thickness of 50 nm of alumina was exceeded.
This optimized honeycomb structure failed at a pressure of 28 kg/mm2, yet only had a density of 810 kg/m3, which the team says exceeds the stability/density ratio of bones, massive steel or aluminum.
"The novel lightweight construction materials
resemble the framework structure of a half-timbered house with
horizontal, vertical, and diagonal struts,” said study co-author Jens
Bauer. "Our beams, however, are only 10 µm in size.”
The team says microstructured materials are often
used for insulation or as shock absorbers, and that such open-pore
materials can be used as filters in the chemical industry.

New materials developed that are as light as aerogel, yet 10,000 times stronger
June 22, 2014
http://www.gizmag.com/llnl-ultralight-metamaterial/32589/?li_source=LI&li_medium=default-widget
Imagine materials strong enough to use in building airplanes or motor cars, yet are literally lighter than air. Soon, that may not be so hard to do because a team of researchers from MIT and Lawrence Livermore National Laboratory (LLNL) have developed new ultra-lightweight materials that are as light as aerogel, but 10,000 times stiffer, and may one day revolutionize aerospace and automotive designs.
Aerogels are incredibly light, so light that the record holder, aerographene, boasts a density of just 0.16 mg/cm3. Currently, aerogels are used for insulation, tennis racquets, as a means of controlling oil spills, and were used on the NASA Stardust mission to collect samples from a comet’s tail. Unfortunately, despite its seemingly ephemeral nature, its very much a solid and will shatter if pressed hard enough, so its use is limited.
The new materials developed by the MIT/LLNL team aren't aerogels, but are metamaterials. That is, artificial materials with properties that aren't found in nature. The idea is to structure it, so that it has the lightness of aerogel, but is much stronger. The strength of the new materials comes from their geometric structure, not their chemical composition.
The new materials were made using projection micro-stereolithography, a form of desktop 3D printing that works on a microscopic level and can create highly complex, three-dimensional microstructures layer by layer very quickly for easy prototyping. It involves projecting a beam of ultraviolet light into a tank of polymers, responsive hydrogels, shape memory polymers, or bio-materials using the digital stereolithography technique in the form of masks, similar to those used to create microchips, to shape the layers.
Projection micro-stereolithography operates on a very small scale that allows the formation of "microlattices," which are much like trusses and girders. Materials can even be switched during fabrication. According to the team, it can be applied to many different materials, including polymers, metals and ceramics, which is exactly what the team did using a variety of constituent materials.
Firstly, the LLNL/MIT team made a polymer template coated with a metal film 200 to 500 nanometers thick, then the polymer base was melted away, leaving behind the metal in the form of thin-film tubes.
The team then used the same technique but replaced the metal with ceramic to create ceramic tubes about 50 nanometers thick, which produced a material with the properties of an extremely stiff aerogel, four orders of magnitude stiffer than conventional aerogel, but with the same density...

New experimental research exposes the strength of beryllium at extreme conditions
August 5, 2015
http://phys.org/news/2015-08-experimental-exposes-strength-beryllium-extreme.html#jCp
The technique involves setting off a piece of high explosives (HE) near the Be. On the side of the Be facing the HE, the team imposed a sinusoidal ripple pattern designed by co-author Jon Belof. When the expanding HE products load up against the target, the target accelerates. Since there is a low density gas pushing against a higher density metal, the interface is Rayleigh-Taylor unstable and the ripples grow in amplitude as the target accelerates.
If the target has no strength, the ripples will grow indefinitely and become turbulent at some point. However, since the Be does have strength, the ripple growth is limited by the strength of the material itself. The main diagnostic for the experiments is an X-ray image from the side of the target showing the height of the ripples at some time after the HE loading has occurred. The other diagnostic is velocimetry of the target showing its acceleration profile.

Bamboo inspires new process for making metals tougher
July 3, 2014
Steel is a common benchmark against which the strength of materials
is measured, with "stronger than steel" a familiar catch cry for those
touting the properties of some new space-age material. But now
researchers at North Carolina State University have created steel that
is stronger than steel using a process that increases the toughness of various metals by altering the microstructures within them.
Inspired by the internal structure of bones and
bamboo, which both boast impressive strength-to-weight ratios, the
researchers were able to increase the strength and toughness of metals
by giving them what the researchers refer to as a "gradient structure."
This is a structure where the size of the millions of tightly-packed
grains that make up the metal are gradually increased further down into
the material...

Comparison of composites made from fungal defibrated hemp with composites of traditional hemp yarn [2007]
Abstract:
Aligned epoxy-matrix composites were made from hemp fibres defibrated
with the fungi Phlebia radiata Cel 26 and Ceriporiopsis subvermispora
previously used for biopulping of wood. The fibres produced by
cultivation of P. radiata Cel 26 were more cellulose rich (78%, w/w)
than water-retted hemp due to more degradation of pectin and lignin. The
defibrated hemp fibres had higher fibre stiffness (88-94 GPa) than the
hemp yarn (60 GPa), which the fibre twisting in hemp yarn might explain.
Even though mild processing was applied, the obtained fibre strength
(643 MPa) was similar to the strength of traditionally produced hemp
yarn (677 MPa). The fibre strength and stiffness properties are derived
from composite data using the rule of mixtures model. The fibre tensile
strength increased linearly with cellulose content to 850 MPa for pure
cellulose. The fibre stiffness increased also versus the cellulose
content and cellulose crystallinity and reached a value of 125 GPa for
pure crystalline cellulose.

at Germany's Fraunhofer Institute for Wood Research, however, have
developed a reportedly greener alternative that they claim works just as
well – it's foam made from wood.
To produce the foam, wood particles are first ground
so small that they form into a slimy solution. A gas is then added to
that slime, causing it to take on a frothy consistency. Once that froth
hardens – a process that is "aided by natural substances contained in
the wood" – a dry, porous foam is the result. The finished product can
take the form of either rigid foam boards, or flexible mats.
The slime can also be converted into foam via induced chemical reactions.

Wood pulp extract stronger than carbon fiber or Kevlar
September 3, 2012
http://www.gizmag.com/cellulose-nanocrystals-stronger-carbon-fiber-kevlar/23959/?li_source=LI&li_medium=default-widget
The Forest Products Laboratory of the US Forest Service has opened a US$1.7 million pilot plant for the production of cellulose nanocrystals (CNC) from wood by-products materials such as wood chips and sawdust. Prepared properly, CNCs are stronger and stiffer than Kevlar or carbon fibers, so that putting CNC into composite materials results in high strength, low weight products. In addition, the cost of CNCs is less than ten percent of the cost of Kevlar fiber or carbon fiber. These qualities have attracted the interest of the military for use in lightweight armor and ballistic glass (CNCs are transparent), as well as companies in the automotive, aerospace, electronics, consumer products, and medical industries.

Nanotubes with two walls have singular qualities
April 15, 2015
Rice University researchers have determined that two walls are better than one when turning carbon nanotubes into materials like strong, conductive fibers or transistors.
Rice materials scientist Enrique Barrera and his colleagues used atomic-level models of double-walled nanotubes to see how they might be tuned for applications that require particular properties. They knew from others' work that double-walled nanotubes are stronger and stiffer than their single-walled cousins. But they found it may someday be possible to tune double-walled tubes for specific electronic properties by controlling their configuration, chiral angles and the distance between the walls.

Delicately opening a band gap in graphene enables high-performance transistors
September 21, 2015
Electrons can move through graphene with almost no resistance, a property that gives graphene great potential for replacing silicon in next-generation, highly efficient electronic devices. But currently it's very difficult to control the electrons moving through graphene because graphene has no band gap, which means the electrons don't need to cross any energy barrier in order to conduct electricity. As a result, the electrons are always conducting, all the time, which means that this form of graphene can't be used to build transistors because it has no "off" state. In order to control the electron movement in graphene and enable "off" states in future graphene transistors, graphene needs a non-zero band gap—an energy barrier that can prevent electrons from conducting electricity when desired, making graphene a semiconductor instead of a full conductor.http://phys.org/news/2015-09-delicately-band-gap-graphene-enables.html#jCp

treatments. Graphene-sheet fibers (GSFs) were fabricated from dried
coffee
grounds loaded in a nickel case using 2.45 GHz microwave plasma system at
the power of 900 W, which was equipped with a rectangular waveguide to couple
the microwave through quartz tube for generating the plasma. In the system, no
additional
heater was installed for substrate heating. The substrate temperature
was controlled by microwave power and plasma exposure time, and was
measured by a thermocouple placed in direct contact with the substrate
holder.
After the deposition chamber was pumped down to a base pressure of 1 Torr
by
a rotary pump with the pumping gas rate of 300L/s, the hydrogen and
argon gases were introduced into the chamber and produced the plasma to
irradiate the coffee grounds for 15 min. The maximal temperature was 650

After deposition, the plasma was shut down and the equipment was
naturally cooled to room temperature. The yield of GSFs was found to be
10-20% in all produced nanocarbons.

It's a wrap: clingfilm alternatives to help you ditch the plastic
Dec 2020
Four ways to store food while cutting out the plastic, from beeswax to vegan-friendly leaf wrap
1. Lakeland compostable perforated clingfilm, £3.99 for a 30-metre x 28.5cm-wide roll, perforated every 30cm
Produced
by an Italian supplier, the polyester film is designed to break down
under home and industrial home composting conditions, and it is claimed
that it will disappear within 12 months without leaving any harmful
residue in the compost.
Instructions on the packaging make clear
that it should not be used in ovens, grills or the microwave. The
perforations are handy, as it is difficult to cut the film with
scissors.
When we wrapped a slightly soggy cheese and tomato
sandwich, the clingfilm did not stick together or “cling” very well, so
we would not be confident about its durability if carried around. That
said, it is strong and did its job perfectly when used to cover food in
containers in the fridge, with no whiff evident from an open pot of
tuna. It can also be used in the freezer, although it was hard to tell
whether it would survive long-term.
Overall verdict: An
affordable guilt-free film that is useful for many kitchen jobs but
cannot be used for cooking and does not have the “clingability” of the
standard version.

Researchers develop viable, environmentally-friendly alternative to Styrofoam
May 9, 2019
Washington
State University researchers have developed an
environmentally-friendly, plant-based material that for the first time
works better than Styrofoam for insulation.
The foam is mostly
made from nanocrystals of cellulose, the most abundant plant material on
earth. The researchers also developed an environmentally friendly and
simple manufacturing process to make the foam, using water as a solvent
instead of other harmful solvents.
The work, led by Amir Ameli,
assistant professor in the School of Mechanical and Materials
Engineering, and Xiao Zhang, associate professor in the Gene and Linda
School of Chemical Engineering and Bioengineering, is published in the
journal Carbohydrate Polymers.
Researchers have been working to
develop an environmentally friendly replacement for polystyrene foam, or
Styrofoam. The popular material, made from petroleum, is used in
everything from coffee cups to materials for building and construction,
transportation, and packaging industries. But, it is made from toxic
ingredients, depends on petroleum, doesn't degrade naturally, and
creates pollution when it burns.
While other researchers have
created other cellulose-based foams, the plant-based versions haven't
performed as well as Styrofoam. They are not as strong, don't insulate
as well, and degraded at higher temperatures and in humidity. To make
cellulose nanocrystals, researchers use acid hydrolysis, in which acid
is used to cleave chemical bonds.

Could ‘Nanowood’ Replace Styrofoam?
March 26, 2018
Scientists at the University of Maryland have developed a biodegradable material that is both strong and a good insulator
Researchers
at the University of Maryland have developed a super-lightweight
insulating material they say could prove to be a better, more
eco-friendly alternative. The material, made from tiny wood fibers, is
called nanowood. It blocks heat at least 10 degrees better than
Styrofoam or silica aerogel, a common insulator, and it can take at
least 30 times more pressure than Styrofoam or silica aerogel before
being crushed.
Working in the lab of materials scientist
Liangbing Hu, postdoctoral researcher Tian Li is the lead author on the
study, published this month in the journal Science Advances.
“To
the best of our knowledge, the strength of our nanowood represents the
highest value among available super insulating materials,” wrote the
study authors.

Green alternatives to styrofoam insulation
April 8, 2019
1. Greensulate
Greensulate
is a good alternative to Styrofoam insulation. The material is
biodegradable and renewable in nature. Besides being a good insulator,
the material is also resistive to fire. You must have seen mushroom
being served at your favorite restaurant, but have you ever thought of
the idea of mushrooms inside your walls, protecting it from moisture and
other environmental hazards. Mushrooms form the basic element in making
Greensulate. A mixture of agricultural bio-waste grows mushrooms into
shapes to make insulation. One has to add Fungal cells in addition with
hydrogen peroxide, to prevent unwanted fungal growth. It is cheaper than
polystyrene and more Eco-friendly. This should serve as enough
incentives to try this material.
Greensulate is a reality because
of the research done by two mechanical engineers – Eben Bayer and Gavin
McIntyre. They, along with other members, are now corporate under the
name Ecovative Designs that provide Eco-friendly Greensulate materials
for a myriad of purposes.
2. Aerogel
Aerogel is a
translucent gel-like material that has a higher R-value than Styrofoam.
The material has low density and thermal conductivity, and porous in
nature. The translucent nature of the material has given it odd names
like frozen smoke, liquid smoke, etc. The low thermal conductivity is
due to the fact that it negates four ways of heat transfer – convection,
conduction, and radiation. Besides insulation, NASA has used Aerogel to
collect space dust. Through the process of supercritical drying, the
liquid component of the gel is taken out to make the material. The
nature of the gel depends on the material from. One can easily extract
it. Most common Aerogel materials have silica, carbon and alumina as
their constituents. Commercially, Aerogel comes in granular form for
insulation and absorption of infrared radiation.
The toxicity of the gel depends on its material. Silica-based Aerogel is not toxic and one can safely use it in homes.
3. Durisol’s green insulated concrete
Durisol,
a Canada based company, is the leading manufacturer of cement-bonded
wood fiber products. Since 1945, they have been making Durisol products
in their 14 manufacturing units located throughout the world. Durisol is
the name of the concrete, which constitutes a mixture of wood fiber and
Portland cement. It requires 100% recycled wood in the manufacturing
process. The origin of the material goes back to Switzerland, where it
was invented to provide a cheap building material to rebuild post world
war Europe. Currently, the company has a host of Durisol products that
include Flat Durisol Sheets, Concrete Wall Accessories, ICF Wall forms
and many more.
Durisol concrete forms are cheap, good insulators, Eco-friendly and strong as conventional concrete blocks.
4. Cellulose insulation
People
had been using Cellulose insulation in the ancient world, long before
the discovery of petroleum. We have now rediscovered the use of such
insulation in the wake of environmental crisis. The traditional
Cellulose material is purely organic and made from plant fibers, but the
modern variant uses recycled newspaper, saw dust, cotton, corncob, hemp
and cardboard. Commercially, Cellulose is available in dry loose fill,
wet-spray Cellulose, stabilized Cellulose and low-dust Cellulose. The
R-value of the material is 3.8 per square inch, little lower than
Styrofoam. It is a good insulator for walls, electrical wiring and
pipes. A wall filled with Cellulose insulation may have little or no air
pockets, thus increasing the efficiency of the insulation. The material
is resistive to vapors and molds, and is non-combustible.
The major disadvantage of Cellulose insulation is that it can increase the inflow of dust inside the house.
5. Denim insulation
When
talking about Denim, the first thing that comes in our mind is Jeans.
Denim insulation is nothing but recycled industrial cotton. Makers of
such materials are not going after throw away jeans; rather they are
taking the scraps that the textile industry is producing. 85% of the raw
material comes from scraps.
The insulation is cheap, 100%
recycled, treated with fire-resistant chemicals, and free from VOC and
formaldehyde. Furthermore, it’s installation does not require a
specialist to meddle in the process.
6. Icynene
Icynene
is a liquid insulation material that is mixed with water and sprayed
through a blower on to the wall. It is made from castor oil. The liquid
turns into foam when it hits the wall. The R-value of the material is
3.6 per square inch. It forms an effective air tight layer on the wall,
and traps air in bubbles moment it settles down. The air tight feature
makes it compulsory to built effective ventilation to assist air flow.
Moreover, it allows water vapor to escape hence prevents accumulation of
water.
Icynene may not be a viable option for people who are
looking for a cost-effective solution to insulation as Icynene is
expensive.
7. Straw bale insulation
Straw-bale as an
insulator has long been known to us. Straw being an agricultural
byproduct is clean and green. The material is fire-resistant and retards
sound. In addition, according to popular belief, Bale insulation can
reduce 75% of the heating cost. Commonly used bales of straw in
construction are derived from rice, wheat, oat and rye. The R-value of
the material varies from 0.94 to 2.38 per square inch. Besides being
clean, it is also cost-effective.
Straw-bale insulation may not be suitable in extreme cold climates, because of the low R-value.

making them an excellent choice for sustainable living.
One
example of natural fiber packaging is molded pulp trays that can be used
for food or electronics. These trays are made from recycled paper waste
and can be easily composted after use.
Another option is using
jute bags instead of plastic bags when shopping for groceries or
carrying items around town. Jute bags are durable, reusable, and
biodegradable.
Using natural fiber packaging not only helps
reduce waste but also supports the growth of sustainable industries that
prioritize environmental responsibility in their production processes.
Bagasse Containers
Bagasse
is a byproduct of sugarcane processing, and it’s often discarded as
waste. However, this material can be repurposed into eco-friendly
packaging products such as plates, bowls, and takeout containers.
Bagasse
containers are sturdy and durable enough to hold hot or cold food items
without leaking or breaking down quickly. They’re also microwave-safe
and freezer-safe for added convenience.
Using bagasse products
instead of Styrofoam not only helps reduce waste but also supports
sustainable agriculture practices by utilizing sugarcane residue that
would otherwise go unused.

Dutch Students Make Leather from Fruit Waste
September 1, 2015
http://www.greenoptimistic.com/leather-fruit-waste/#.Ve-t05e-2zk
They developed a method to produce a new material from the fruit and vegetable left-overs. As the name of the initiative suggests, the new material is called “fruit leather“, and it is created by processing spoiled biological plant waste. This new type of vegan leather can be used to make all sorts of products, from handbags to furniture, and it can potentially have the same quality as its animal ancestor after a few more improvements are made.
The young designers have not yet released their precise method, I am guessing because of a patent or a possibility for commercializing the product, but in general it involves cleaning, mashing, boiling and then drying of the waste.

Making clothes out of gelatin could reduce agricultural waste
June 24, 2015
From gummy bears to silky mousses, gelatin is essential for making some of our favorite sweets. Now scientists are exploring another use for the common food ingredient: spinning it into yarn so it can be made into clothing. And because gelatin comes from livestock by-products, the new technique would provide an additional use for agricultural leftovers. The report appears in the ACS journal Biomacromolecules.
More than a century ago, the textile industry started using protein fibers from animals and vegetables such as casein from milk and zein from corn to make new kinds of fabrics. But synthetic fibers derived from petroleum products boomed and quickly eclipsed those efforts. Now, as consumers search for "greener" products, scientists have revived the idea of making fabrics from animal and plant proteins. Wendelin J. Stark and colleagues decided to try spinning yarn out of gelatin, which comes from collagen, an abundant protein in livestock by-products.
The researchers spun filaments of gelatin, twisted them into a yarn and then treated it with gaseous formaldehyde and lanolin (wool grease) to make it water-resistant. The resulting yarn was about as strong as a strand of merino wool. It was also just as warm when knitted into a glove.

MIT group explores bacteria use for comfort wear
October 30, 2015
Now they are using the bacteria in a new way—it becomes a nanoactuator that expands and shrinks based on atmospheric moisture or the sweat of the skin. As Gizmodo wrote, the team was interested in the possibilities: "if natto's expansion and contraction could be carefully calibrated, perhaps it could act more like a machine than an unpredictable organism. Perhaps it could act more like an actuator."
The team said, "We introduce a specific type of living cells as nanoactuators that react to body temperature and humidity change. The living nanoactuator can be controlled by electrical signal and communicate with the virtual world as well." A digital printing system and design simulation software were developed too.

Scientists are using bacteria to remove harmful contaminants from our water. Here's how.
January 10, 2019
https://www.ehn.org/scientists-are-using-bacteria-to-remove-harmful-contaminants-from-our-water-heres-how-2625517276.html
John
Coates' laboratory at the University of California, Berkeley, hums with
activity. Negative 80-degree freezers whirr, liquid nitrogen bubbles,
grad students meticulously measure and mix complicated concoctions. But
all of this is nothing compared with the commotion going on at a
microscopic level.
The Coates lab is growing many different kinds
of bacteria, multiplying in petri dishes at mind-boggling rates. But
these bacteria aren't out to harm people or animals. In fact, quite the
opposite — they're hard at work breaking down a dangerous chemical that
pollutes waterways across the United States.
The chemical, called
perchlorate, comes from rocket fuel, munitions and fireworks. It's
dangerous to humans because it can impair thyroid function. It can also
affect the thyroid in freshwater animals like fish and amphibians, even
altering gonad development in some animals. But certain bacteria,
including several species of Dechloromonasand Azospira, have evolved to
use perchlorate to make energy-storing molecules. In the process, they
turn it into harmless chloride and oxygen.
Coates is just one of
many scientists across the globe who are working to harness the ability
of various bacteria to remove harmful pollutants from water. This is no
easy task. There are thousands of different pollutants — industrial
chemicals, pesticides, herbicides, fertilizers, metals and more — and no
one microbe can break down all. Also, because bacteria need special
conditions to survive, it can be difficult to incorporate them into
water treatment systems.
In spite of these challenges, Coates
sees a future full of possibility. "It's really just a question of
sitting down and spinning your brain around all the cool, novel aspects
of these organisms and then asking where can we apply this?" he says.
Perchlorate decon
Perchlorate
is mostly used in rocket fuels and munitions. Improper storage or
disposal of rockets or debris may contaminate the environment. Through
leaks or explosions, perchlorate can also pollute waterways near
manufacturing plants. It's water soluble and chemically stable, so it
can persist in ground and surface water for decades.
And that's
bad news for people whose drinking water comes from contaminated
sources, especially pregnant women and children. Perchlorate has been
shown to impair thyroid function; proper thyroid function is essential
for normal brain development during the prenatal period and during
childhood.
When Coates submitted his first academic paper on
perchlorate-degrading bacteria in 1998 (it was published in 1999), there
were only a few bacterial species known to be capable of performing
this feat. Coates wanted to see if there were more.
"It turns out
that the microorganisms that use perchlorate are essentially ubiquitous
— they're not difficult to find. And you can culture them fairly
readily. To remediate perchlorate, you just needed to create specific
conditions," he says.
The way to do this is to use something
called a bioreactor — a home for bacteria that provides all the
nutrients and minerals they need to thrive. It's similar to a fermenting
tank for beer, except instead of yeast converting sugars into alcohol
and carbon dioxide, perchlorate-destroying bacteria turn dangerous
perchlorate into harmless chloride and oxygen. Contaminated ground or
surface water gets pumped into the bioreactors, which are full of these
bacteria. Once the bacteria have broken down the perchlorate, the water
is filtered and sterilized to remove bacteria. The decontaminated water
can then be sent to consumers or pumped back into the ground.
Thanks
to discoveries made by Coates and a legion of other scientists,
perchlorate-decontaminating bioreactors have been applied in the real
world with great success. Large-scale perchlorate bioreactors are now at
work cleaning contaminated water at several sites in California,
Kansas, Texas and Utah. These bioreactors are astonishingly efficient:
The bioreactor-based groundwater treatment plant in Rialto, California,
for example, is capable or decontaminating 2,000 gallons (over 7,500
liters) of perchlorate-polluted water per minute — that's more than a
billion gallons (over 3.7 billion liters) a year. In fact, Coates says
that the bacterial removal of perchlorate represents one of the
largest-scale bioremediation projects in the world.
Converting uranium
Implementing
bioreactor technologies isn't always so straightforward, even when the
bioreactor performs well in the lab. A bioreactor designed by Bruce
Rittmann, the director of the Swette Center for Environmental
Biotechnology at Arizona State University's Biodesign Institute, was
initially used to remove water contaminants like perchlorate and
trichloroethene, but can also be used to remove uranium and other metals
from water. This kind of contamination can occur around uranium mines
and mills, especially older abandoned ones. In people, drinking water
contaminated with uranium can cause kidney damage; uranium is also toxic
to fish, decreasing their reproductive success.
The bacteria in
the bioreactor can't destroy the uranium, but they can convert it to a
form that separates from water. Once the uranium comes out of the
solution, it's much easier to remove —think about the difference between
taking a sugar cube out of a glass of water and trying to remove the
sugar once it's dissolved. In tests, Rittmann's bioreactor removed about
95 percent of the uranium from a contaminated water supply.
Rittmann
says it would be relatively straightforward to construct a bioreactor
system in currently operational mines that already have some sort of
water treatment system in place. However, cleaning up abandoned mines
would be more difficult, since they have no such infrastructure. There
are about 4,000 abandoned uranium mines in America's western states.
This
technology, Rittmann says, can be applied not just to water
contaminated by uranium mines but also to wastewater from precious metal
mines, including silver, gold and palladium. "In these cases, the
materials that we produce — the solids these microbes remove from the
water — are really valuable. We're working on the development of this
technology not only to remove pollutants but to generate high value.
It's a good deal," he says.
Beyond the bioreactor
What if
we want to break down pollutants in places where building bioreactors
isn't feasible, like in runoff from agricultural fields contaminated
with pesticides? Colin Scott, head of the Biocatalysis & SynBio Team
at Australia's Commonwealth Scientific and Industrial Research
Organization (CSIRO), may have an answer.
Bacteria make enzymes,
and it's these enzymes that do the dirty work of actually breaking down
pollutants. So, Scott and his team are experimenting with bacterial
enzymes to decontaminate water systems polluted with pesticides and
herbicides. Enzymes aren't alive, so they don't need nutrients, which
means they can be used in places that bacteria won't survive. They can't
reproduce or adapt, so won't multiply and disturb delicate ecosystems.
"Enzymes
themselves are terrific because they're really specific for the thing
that you want them to do, so they don't have any other effects. And
they're also biodegradable, so they don't persist in the environment,"
says Scott.
Such enzymes are not yet used on a large scale, but
they've been successful in field tests. For example, a bacterial enzyme
called OP-A is capable of breaking down organophosphate insecticides,
which have been linked to deficits in attention, coordination and
memory, especially in agricultural workers. In field trials, the OP-A
enzyme reduced levels of the controversial pesticide chlorpyrifos —
linked to impaired brain development in children — in contaminated field
runoff by 99 percent in just eight hours. (Since these tests, the
researchers say they have developed an improved version of OP-A, known
as A900.)
The specificity of enzymes is both their brilliance and
their downfall. On one hand, high specificity means that enzymes aren't
likely to produce unwanted side effects, like harming plants or
animals. On the other hand, there are thousands of different pollutants,
which means we'll need a lot of different enzymes.
After an
appropriate enzyme has been identified, scientists have to figure out
how to cost-effectively mass produce it. Since enzymes usually
biodegrade quickly, scientists have to make sure the enzyme stays intact
long enough to do its job. They also have to run safety studies to make
sure that whatever components the enzymes break the pollutant down into
aren't also toxic.
A long way to go
There's still a lot
of work to be done. At the science level, we need to identify and
characterize bacteria that can break down specific pollutants. Although
bacteria for degrading or removing contaminants like perchlorate,
uranium and certain pesticides are well understood, as-yet undiscovered
bacteria may be important in dealing with emerging water pollutants such
as PFAS, which can cause immune system dysfunction and cancer, as well
as pharmaceuticals, the effects of which are not yet fully understood.
Other
hurdles are policy based. It's often not a question of whether to use
bioremediation or alternative techniques, but whether to do anything at
all. Many contaminants — including several pesticides, cyanotoxins and
solvents — are monitored by the EPA, but not regulated. Without set
limits for acceptable amounts of these chemicals in drinking water,
there's no incentive for anyone to spend money to get rid of them. Even
though bioremediation may be cheaper than the alternatives, in the short
term, it's still more expensive than doing nothing. And for many
pollutants — including many pesticides — there's currently a whole lot
of nothing being done.
But with the continued work of scientists and stricter water quality standards, bacteria could be a public health game-changer.
"These bugs are amazing," says Coates. "What limits us is our imagination rather than the organisms' abilities."

Environmental remediation by tea waste and its derivative products: A review on present status and technological advancements
2022 Apr 5
Abstract
The
rising consumption of the popular non-alcoholic beverage tea and its
derivative products caused massive growth in worldwide tea production in
the last decade, leading to the generation of huge quantities of waste
tea residues every year. Most of these wastes are usually burnt or
disposed in landfills without proper treatment which results in serious
environmental issues by polluting water, air and soil. In the recent
times, 'waste to wealth' is a fast-growing concept for environment
friendly sustainable development. Utilization of the large amount of tea
wastes for the production of low-cost adsorbents to reduce the expenses
of water and wastewater treatment can be a sustainable way of
management of these wastes which at the same time will improve circular
economy also. This review endeavours to evaluate the potential of both
raw and modified tea wastes towards the adsorption of pollutants from
wastewater. The production of various adsorptive materials such as
biochar, activated carbon, nanocomposites, hydrogels, nanoparticles from
tea wastes are summarized. The advancements in their applications for
the removal of different emerging contaminants from wastewater as well
as potable water, air and soil are exhaustively reviewed. The outcome of
the present review reveals that tea waste and its derivatives are
appropriate candidates to be used as adsorbents that show tremendous
effectiveness in cleaning the environment. This article will provide the
readers with an in-depth knowledge on the sustainable utilization of
tea waste as adsorbent materials and will assist them to explore this
abundant cheap waste biomass for environmental remediation.

immobilization onto magnetite nanoparticles for phenol removal
30 October 2023
Abstract
In this study, melon peel waste was utilized to isolate peroxidase
enzyme through three-phase portioning (TPP) and subsequently immobilized
onto magnetite nanoparticles for effective bioremediation of phenol
pollutants from water. The optimization of TPP parameters ensured
maximum activity recovery and enzyme purity. Magnetite nanoparticles
were synthesized and used as a substrate for immobilizing the isolated
peroxidase, achieving an activity recovery of 157% and a purification
fold of 5.2. Protein homogeneity testing confirmed the purity of the
peroxidase enzyme. The magnetite nanoparticles had an average diameter
of 62 nm, and the immobilization efficiency reached 93% at pH 8 with an
enzyme/nanoparticles v/v ratio of 1:9. The immobilized peroxidase
demonstrated the ability to degrade 57% of phenol within 3 h and
retained 30% relative activity even after five catalytic cycles. This
immobilized melon peel peroxidase on magnetite nanoparticles proves to
be a robust, enduring, and reusable biocatalyst with potential for
various applications, especially in bioremediation processes.

Recent Strategies for Bioremediation of Emerging Pollutants: A Review for a Green and Sustainable Environment
2022 Aug 19
Abstract
Environmental
pollution brought on by xenobiotics and other related recalcitrant
compounds have recently been identified as a major risk to both human
health and the natural environment. Due to their toxicity and
non-biodegradability, a wide range of pollutants, such as heavy metals,
polychlorinated biphenyls, plastics, and various agrochemicals are
present in the environment. Bioremediation is an effective cleaning
technique for removing toxic waste from polluted environments that is
gaining popularity. Various microorganisms, including aerobes and
anaerobes, are used in bioremediation to treat contaminated sites.
Microorganisms play a major role in bioremediation, given that it is a
process in which hazardous wastes and pollutants are eliminated,
degraded, detoxified, and immobilized. Pollutants are degraded and
converted to less toxic forms, which is a primary goal of
bioremediation. Ex situ or in situ bioremediation can be used, depending
on a variety of factors, such as cost, pollutant types, and
concentration. As a result, a suitable bioremediation method has been
chosen. This review focuses on the most recent developments in
bioremediation techniques, how microorganisms break down different
pollutants, and what the future holds for bioremediation in order to
reduce the amount of pollution in the world.

BOX 2-1 KEY TERMS FOR UNDERSTANDING BIOREMEDIATION
Microorganism:
An organism of microscopic size that is capable of growth and
reproduction through biodegradation of "food sources," which can include
hazardous contaminants.
Microbe: The shortened term for microorganism.
Oxidize:
The transfer of electrons away from a compound, such as an organic
contaminant. The coupling of oxidation to reduction (see below) usually
supplies energy that microorganisms use for growth and reproduction.
Often (but not always), oxidation results in the addition of an oxygen
atom and/or the loss of a hydrogen atom.
Reduce: The transfer of electrons to a compound, such as oxygen, that occurs when another compound is oxidized.
Electron
acceptor: The compound that receives electrons (and therefore is
reduced) in the energy-producing oxidation-reduction reactions that are
essential for the growth of microorganisms and bioremediation. Common
electron acceptors in bioremediation are oxygen, nitrate, sulfate, and
iron.
Electron donor: The compound that donates electrons (and
therefore is oxidized). In bioremediation the organic contaminant often
serves as an electron donor.
Primary substrates: The electron
donor and electron acceptor that are essential to ensure the growth of
microorganisms. These compounds can be viewed as analogous to the food
and oxygen that are required for human growth and reproduction.
Aerobic respiration: The process whereby microorganisms use oxygen as an electron acceptor.
Anaerobic
respiration: The process whereby microorganisms use a chemical other
than oxygen as an electron acceptor. Common "substitutes" for oxygen are
nitrate, sulfate, and iron.
Fermentation: The process whereby
microorganisms use an organic compound as both electron donor and
electron acceptor, converting the compound to fermentation products such
as organic acids, alcohols, hydrogen, and carbon dioxide.
Cometabolism:
A variation on biodegradation in which microbes transform a contaminant
even though the contaminant cannot serve as the primary energy source
for the organisms. To degrade the contaminant, the microbes require the
presence of other compounds (primary substrates) that can support their
growth.
Reductive dehalogenation: A variation on biodegradation
in which microbially catalyzed reactions cause the replacement of a
halogen atom on an organic compound with a hydrogen atom. The reactions
result in the net addition of two electrons to the organic compound.
Intrinsic
bioremediation: A type of bioremediation that manages the innate
capabilities of naturally occurring microbes to degrade contaminants
without taking any engineering steps to enhance the process.
Engineered
bioremediation: A type of remediation that increases the growth and
degradative activity of microorganisms by using engineered systems that
supply nutrients, electron acceptors, and/or other growth-stimulating
materials.
Variations on Basic Metabolism
In addition
to microbes that transform contaminants through aerobic respiration,
organisms that use variations on this basic process have evolved over
time. These variations allow the organisms to thrive in unusual
environments, such as the underground, and to degrade compounds that are
toxic or not beneficial to other organisms.
Anaerobic
Respiration. Many microorganisms can exist without oxygen, using a
process called anaerobic respiration. In anaerobic respiration, nitrate
(NO3-), sulfate (SO42-), metals such as iron (Fe3+) and manganese
(Mn4+), or even CO2 can play the role of oxygen, accepting electrons
from the degraded contaminant. Thus, anaerobic respiration uses
inorganic chemicals as electron acceptors. In addition to new cell
matter, the byproducts of anaerobic respiration may include nitrogen gas
(N2), hydrogen sulfide (H2S), reduced forms of metals, and methane
(CH4), depending on the electron acceptor.

Principles of Phytoremediation
20 March 2020
Abstract
Phytoremediation,
a form of bioremediation, is one viable option for removing pollution
from contaminated soil and water. Bioremediation was developed as an
inexpensive, environmentally friendly, and sustainable alternative to
traditional chemical and physical pollution remediation methods.
Bioremediation began with the use of bacteria and later other
microorganisms, to extract or degrade inorganic and organic contaminants
in soil and water in situ. It then evolved to other applications in
combination with traditional chemical and physical remediation methods.
Phytoremediation was came about from basic research studies on the
physiology of halophytic and hyperaccumulating plants. At first, plants
provided successful for extracting salts, metals, and radionuclides from
soil and water. Further, studies discovered that plant roots and the
rhizosphere were capable of extracting or degrading organic pollutants
such as pesticides and petrochemicals. The in situ case studies
showcased in this book demonstrate how phytoremediation is a sustainable
means of pollution remediation in economically emerging countries and
is consistent with the United Nations Sustainable Development Goals.

Soil and Groundwater Remediation Technologies: A Practical Guide

______________
Five ways scientists can make soil less dirty
May 23, 2016
https://www.anl.gov/article/five-ways-scientists-can-make-soil-less-dirty
It
may be hard to imagine, but soil gets dirty. Soil can become
contaminated with oil, grease, heavy metals or pesticides through urban
and agricultural runoff as well as industrial spills or precipitation.
The
clean-up process involves more than a broom and a dust pan. Soil must
undergo remediation — the process of removing pollutants and
contaminants from the ground.
Several different remediation
processes are available, varying in efficiency, cost and sustainability
for specific site conditions. When officials suspect a site is
contaminated, they conduct an assessment to determine the pollutant, the
extent of contamination and the appropriate method to remediate the
soil.
The Applied Geosciences and Environment Management Program
at the U.S. Department of Energy’s Argonne National Laboratory evaluates
potentially contaminated sites and applies remediation methods, such as
those described below, that are both efficient and environmentally
friendly by reducing secondary impacts — such as emissions from trucks
that transport soil to a treatment facility.
Air Sparging
Air
sparging, also referred to as soil venting, involves injecting air into
the soil or groundwater. The air moves horizontally and vertically
through the soil, causing the contaminants to evaporate into a gas. This
method works best for contaminants that easily evaporate, such as crude
oil.
Air sparging is an example of an in-situ remediation
method, in which the contaminated soil does not need to be removed. In
situ methods tend to be more environmentally friendly than those that
are ex situ, where the soil is first removed and then treated at the
surface, said Lorraine LaFreniere, an Argonne geological engineer who
leads Argonne’s Applied Geosciences and Environment Management program.
“In
in situ methods, you’re not bringing any of the contaminants to the
surface,” LaFreniere said. “You have the advantage of not exposing
anybody to the contamination or the remediation process itself.”
Air Stripping
Air
stripping is an ex situ method specifically for water, in which
contaminated groundwater is collected and filtered through a machine
called an air stripper.
The groundwater goes into the top of the
machine and cascades to the bottom as fine droplets, while air enters
from the bottom and is forced upward. The air strips away the
contaminants as it rises through the droplets and exits through an
opening at the top.
Determining whether to use an in situ or ex
situ process depends on how the contamination is distributed throughout
the soil and to what depth, researchers said. For example, if the
contaminated soil is buried under clean soil, the clean soil would have
to first be removed.
Enhanced Biodegradation
Nature itself
tries to help eliminate soil contaminants through a naturally occurring
process called biodegradation. Certain microorganisms in the soil feed
on contaminants, such as tar deposits.
Argonne researchers, in
collaboration with other scientists, found that injecting zero-valent
iron — iron in its elemental form — into the soil accelerates natural
biodegradation.
“We injected slurry mixtures of zero-valent iron
and organic matter into soils and observed that it speeds up the process
considerably,” LaFreniere said.
Phytoremediation
Trees offer
shade on a sunny day, but they can also remove contaminants from soil
through phytoremediation. Trees and other deep-rooted plants absorb
contaminants in soil and incorporate the contaminants into their
tissues; plants also “breathe” volatile contaminants to the atmosphere,
where they dissipate.
“Plants process a lot of water during
photosynthesis to get the nutrients they need,” said Cristina Negri, an
Argonne agronomist and environmental engineer in the Energy Systems
Division. “What we’re doing is exploiting this natural process and
using plants as pumps to remove contaminants.”
Plant-based
remediation is good for contaminants, such as carbon tetrachloride, a
chemical that was primarily used as a fumigant and dry cleaning agent
until it was banned in the 1970s as harmful to human health.
Argonne
researchers are also using trees to monitor their progress when using
phytoremediation. The scientists measure the amount of contaminants in
samples of branches and tree cores to assess how much has been removed.
Soil Vapor Extraction
Sometimes, all you need is a really big vacuum.
The
soil vapor extraction method applies a vacuum to the soil to induce air
flow and get soil vapors moving. Researchers collect the contaminated
vapors in extraction wells and treat them above ground.
This is a
useful remediation method when the contaminants are already in a
vaporous state or are liquids that readily evaporate, such as methane
and propane. These vapors can make their way into homes and businesses
and may cause people to become ill.
“We’re trying to develop new
testing and treatment techniques to best remove contaminants and keep
people safe,” LaFreniere said. “As we’re remediating, we’re also
assessing the methods and technologies that we’re using.”

Energy’s Office of Environmental Management, the Commodity Credit
Corporation and the U.S. Department of Agriculture.

Recent Developments in Microbe–Plant-Based Bioremediation for Tackling Heavy Metal-Polluted Soils
2021 Dec 23
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8733405/
Plant-Based Bioremediation
Plants
are used for bioremediation either alone or in combination with
microbes (Ramos et al., 2005) instead of depending on microbes and their
efficacy in achieving bioremediation of any contaminated medium. The
application of green plants to clean up any contaminated medium or
surface is not a novel concept. Plants were proposed for treating the
wastewater around 300 years ago (Hartman, 1975). Presently a number of
plant species such as Amaranthus spinosus, A. hypochondriacus
Chrysopogon zizanioides, Brassica juncea, Ricinus communis, Chromolaena
odorata, Ageratum conyzoides, Ipomoea carnea, Prosopis juliflora,
Lantana camara, Parthenium hysterophorus, Fagopyrum esculentum,
Odontarrhena chalcidica, Tagetes patula, T. erecta, and Odontarrhena
chalcidica, have been identified which helpremediate HM contaminated
soil (Bauddh and Singh, 2012; Bauddh and Singh, 2015; Huang et al.,
2019; Chen et al., 2020a; Raza et al., 2020; Biswal et al., 2021; Cui et
al., 2021; Gonzaga et al., 2021; Nugroho et al., 2021; Singh et al.,
2021). In addition, plants like Nicotiana tabacum, Arabidopsis thaliana,
Beta vulgaris and Sedum alfredii have been genetically modified with
suitable bacterial genes from Caenorhabditis elegans, Saccharomyces
cerevisiae, Streptococcus thermophilus, Pseudomonas fuorescens and
employed for remediating the targeted contaminants (Daghan et al., 2013;
Liu et al., 2015a; Wang et al., 2019; Nedjimi, 2021). For instance,
mercury (Hg) reductase bacterial genes, e.g., merA and merB have been
applied in plants for the detoxification of methyl-Hg (Li et al.,
2020a). In addition, various biostimulators, such as manure and organic
amendments (e.g., various plant biochar, biosolids, and litter) are used
in this plant-based bioremediation. Use of different chelators such as
citric acid, ethylene diamine tetraacetic acid (EDTA),
[S,S]-ethylenediaminedisuccinic acid (EDDS),
ethylenediamine-di-o-hydroxyphenylacetic acid (EDDHA),
diethylenetriaminepentaacetic acid (DTPA), ethylene glycol tetraeacitic
acid (AGTA), nhydroxyethylenediaminetriacetic acid (HEDTA), fulvic
acids, salicyclic acid, and tartaric acid control metal sorption, and
precipitation through the formation of metal chelate complexes, which
consequently enhance the bioavailability of these metals and also
improve phytoextraction efficiency (Caporale and Violante, 2016; Acuña
et al., 2020; Saleem et al., 2020). The addition of chelates in soils
can move more metals into soil solution via the suspension of
precipitated compounds and desorption of sorbed species. Plants can also
naturally produce various phytosiderophores, organic acids, and
carboxylates, which can enhance metal mobility, solubility, and
bioavailability in soils, thus increasing the phytoremediation potential
of plants (Vithanage et al., 2012; Gupta and Singh, 2017). For
instance, Miscanthus sinensis can detoxify Al by producing various
phytosiderophores such as citric acid, malic acid, and chlorogenic acid
and stored the metal in cell walls (Haruma et al., 2019).
Plant-based
bioremediation is considered a potential tool for the accumulation,
transformation, and immobilization of a low level of contaminants (Rayu
et al., 2012). The mechanisms behind plants facilitate the reclamation
of the polluted soils and groundwater are presented in Table 1. The
approach of plant-based bioremediation has several merits such as
cost-effectiveness, public acceptance, and the ability to remove
inorganic and organic contaminants simultaneously. In a study, mixed
mercury-trichloroethylene (Hg-TCE) pollutants are removed by transgenic
alfalfa plants pKHCG co-expressing human P450 2E1 (CYP2E1) genes and
glutathione S-transferase (GST; Zhang et al., 2013). A major synergistic
effect caused by simultaneous expression of CYP2E1 and GST leads to
increased accumulation and resistance of heavy metal–organic complex
pollutants. Another study by Tammam et al. (2021) found that the plant
Glebionis coronaria can eliminate Pb from the contaminated soil. It is
also recorded that the foliar spray of Indole-3-acetic acid (IAA) and
gibberellic acid (GA3) enhanced the growth significantly and increase
the phytostabilization capacity of the studied plant. The application of
bamboo biochar with the Salix psammophila to remediate the multi-metal
contaminated soil, enhance the translocation factor (TF) and
bioconcentration factors (BCF) of Cd, Cu and Zn (Li et al., 2021a). The
higher TF for Zn (TF > 1) and BCF for Cd (BCF > 1) makes S.
psammophila a potential candidate for the phytoremediation in BBC
amendment soil. Recently several studies found that the application of
nanoparticles such as Ag nanoparticles (AgNPs), nano-TiO2 particles,
nanoscale zero-valent iron (nZVI), salicylic acid nanoparticles (SANPs)
and magnesium oxide (MgO) nanoparticles along with plants Zea mays,
Glycine max, Isatis cappadocica, Lolium perenne, Boehmeria nivea and
Raphanus sativus enhance the growth and phytoextraction of HMs Cd and Pb
(Khan and Bano, 2016; Singh and Lee, 2016; Gong et al., 2017; Souri et
al., 2017; Huang et al., 2018; Hussain et al., 2019).

Soil washing for the remediation of dioxin-contaminated soil: A review
2021
https://www.sciencedirect.com/science/article/abs/pii/S0304389421017325
Introduction
Sites
contaminated with polychlorinated aromatic compounds are a worldwide
problem. One of the most noticeable group of soil contaminants is
polychlorinated dibenzo-p-dioxins and dibenzofurans (or PCDD/Fs or
dioxins) (Kulkarni et al., 2008, Haglund, 2007). In fact, PCDD/Fs, which
are compounds of similar physico-chemical properties and molecular
structures, are one of the most toxic human-made chemicals (Alaee,
2016). Their stability, easy accumulation, and persistence in the
environment along with their ability to cause adverse health effects,
such as wasting syndrome (Seefeld et al., 1984), immunotoxicity (Rhile
et al., 1996), teratogenicity (Mimura et al., 1997), dysfunctional
immune and reproductive systems, and various types of cancers (Steenland
et al., 2004), make them a potential threat to human wellbeing.
PCDD/Fs’
biodegradation is slow, and their half-life in soil is estimated to be
ten years (Habe et al., 2002, Lin et al., 2018). They also have very low
vapor pressure, making them hardly evaporate into the air (Eitzer and
Hites, 1988). The water solubility of PCDD/Fs is very low (e.g. 1.93 ×
10−3 and 0.75 × 10−7 mg/L for 2,3,7,8-tetrachlorodibenzo-p-dioxin
(2,3,7,8-TCDD) and octachlorodibenzodioxin (OCDD) at 25 ℃, respectively)
since they are non-polar and hydrophobic compounds with high
octanol-water partitioning coefficients; therefore, mostly PCDD/Fs
accumulate in soil particles (Atsushi and Yoshihisa, 2008). The
hydrophobicity of dioxins is proportional to the number of chlorine
atoms present on the molecule.
Currently, available remediation
technologies for dioxin-contaminated soil can be classified as thermal
(Lee et al., 2008), physical/chemical (Rathna et al., 2018), and
biological remediation (Huang et al., 2018, Tran et al., 2020). The
selection of a treatment for a specific site mostly depends on PCDD/F
removal efficiency, soil detoxification, and cost. Soil
washing/extraction is a physicochemical remediation process that has
been widely studied in recent years due to its high removal efficiency,
ease in operation, and cost-effectiveness. Soil washing uses physical
forces (e.g., generated by propellers/impellers) and liquid solvents
(chemical extraction) to remove contaminants from soil (Cheng et al.,
2017). Physical separation in soil washing can help separate fine
particles (clay and silt), which often have a larger surface area and
thus higher PCDD/F concentrations, from coarse particles (sand and
gravel) (Jonsson et al., 2010). When in contact with soil particles,
physical forces can break them down, facilitating contaminant removal.
Rotating mixer, ultrasonic basin, mechanical stirrer, and flotation
machine are usually employed for physical separation. Physical
separation can also be combined with chemical extraction to enhance the
remediation efficiency for dioxin-contaminated soil.
Being
hydrophobic makes PCDD/Fs more soluble in organic solvents than in water
(Guemiza et al., 2017a), making organic solvents such as ethanol,
2-propanol, acetone were the earliest reagents used for extracting
dioxins from the soil. The dioxin removal efficiencies range from 75% to
90% for ethanol (Jonsson et al., 2010, Meguro et al., 2008). For
example, Jonsson et al. (2010) indicated that at high initial PCDD/F
concentrations of 2300–8100 pg-Toxicity Equivalent (TEQ)/kg, the
treatment efficiencies were 81–85% after 10 wash cycles with 75%
ethanol. Recently, the use of surfactants or organic matters such as
humic acid, compost, edible oils has shown to be feasible to extract
hydrophobic compounds from soil (Guemiza et al., 2017a). These additives
help increase the solubility of dioxins in the washing liquid.
Surfactants such as Brij 35, Tween 80, Triton X100, and Sodium dodecyl
sulfate (SDS) have been studied for PCDD/F soil washing (Reynier et al.,
2014, Binh et al., 2016). At an initial PCDD/F concentration of 6289
ng-TEQ/kg, the obtained removal efficiencies were 25%, 72%, 70%, and 74%
for Brij 35, SDS, Tween 80, and Triton X100, respectively. Also, Vu et
al. (2017) reported 80–95% removal of dioxins from highly contaminated
soil when it was washed by fish oil and compost tea.
Recently,
two prominent review articles have been published on soil washing
treatment of hydrophobic organic pollutants (Trellu et al., 2016,
Mousset et al., 2014). Trellu et al. (2016) summarized soil
washing/flushing technologies for soil contaminated with
polychlorobiphenyls (PCB), polycyclic aromatic hydrocarbons (PAH), and
petroleum hydrocarbons, as well as the treatment of the washed solution.
This study, unlike many others, described the treatment of the washed
solution in detail. Yet, soil washing was only briefly described.
Mousset et al. (2014) reviewed the use of cyclodextrins in comparison
with other surfactants, cosolvents and agents for the removal of
hydrophobic pollutants from contaminated soil. This study mostly focused
on cyclodextrins and its properties, advantages and uses in soil
washing. Other solvents and surfactants were also involved but only for
the comparison with the efficiency and outstanding properties of
cyclodextrins. These studies, however, have indicated that soil washing
technology is a robust and environmentally friendly treatment with ease
in operation and maintenance. A review on PCDD/F soil washing has not
existed. Also, a detailed summary of physical washing techniques has not
been available in the literature. Further, the cost feasibility of soil
washing has rarely been summarized. Our review article aimed at
bridging these gaps.
In this review, a description of physical
washing devices and chemical extraction processes (using solvents,
surfactants and edible oils) for PCDD/F soil washing was provided. The
advantages and limitations of each technology for PCDD/F soil washing
were presented. Particularly, cost feasibility, one of the most crucial
factors for upscaling a treatment technology, was given.

Soil and brownfield bioremediation
2017 Aug 22
Bioaugmentation
Introducing
specific microorganisms to decontaminate the soils when indigenous
microbes are not efficient is considered a more acceptable approach to
remediate the contaminated soils. However, the strains for
bioaugmentation should ideally have (i) superior ability to degrade the
target contaminants, (ii) easy to cultivate, (iii) fast growth, (iv)
tolerance to the high concentration of contaminant and (v) ability to
survive in a wide range of environmental conditions/stressors.
Bioaugmentation has been proven to be successful for a wide range of
pollutants including pesticides such DDT, lindane, endosulfan,
pentachlorophenol (PCP), polyaromatic hydrocarbons (PAHs) and total
petroleum hydrocarbons (Abhilash et al., 2011; Saez et al., 2014; Wang
et al., 2014; Chen et al., 2015; Kuppusamy et al., 2016a,b). However,
predation, competition and toxins in soils can negatively affect the
survival of introduced microbes. In such cases, bioaugmentation using
immobilized cells in carrier materials or preadapted strains to the
problem soil conditions may prove to be advantageous regarding enhancing
their survival in soils.

Polycyclic Aromatic Hydrocarbons: Sources, Toxicity, and Remediation Approaches
2020 Nov 5
Abstract
Polycyclic
aromatic hydrocarbons (PAHs) are widespread across the globe mainly due
to long-term anthropogenic sources of pollution. The inherent
properties of PAHs such as heterocyclic aromatic ring structures,
hydrophobicity, and thermostability have made them recalcitrant and
highly persistent in the environment. PAH pollutants have been
determined to be highly toxic, mutagenic, carcinogenic, teratogenic, and
immunotoxicogenic to various life forms. Therefore, this review
discusses the primary sources of PAH emissions, exposure routes, and
toxic effects on humans, in particular. This review briefly summarizes
the physical and chemical PAH remediation approaches such as membrane
filtration, soil washing, adsorption, electrokinetic, thermal,
oxidation, and photocatalytic treatments. This review provides a
detailed systematic compilation of the eco-friendly biological treatment
solutions for remediation of PAHs such as microbial remediation
approaches using bacteria, archaea, fungi, algae, and co-cultures. In
situ and ex situ biological treatments such as land farming,
biostimulation, bioaugmentation, phytoremediation, bioreactor, and
vermiremediation approaches are discussed in detail, and a summary of
the factors affecting and limiting PAH bioremediation is also discussed.
An overview of emerging technologies employing multi-process
combinatorial treatment approaches is given, and newer concepts on
generation of value-added by-products during PAH remediation are
highlighted in this review.
Microbial Remediation of Polycyclic Aromatic Hydrocarbon Pollution
As
per Kuppusamy et al. (2017), biological methods have gained wide
attentions for PAH remediation, followed by integrated methods, chemical
oxidation, and physical methods. Among all biological methods for PAH
remediation, usage frequency of natural attenuation, bioaugmentation,
and biostimulation is highest (∼33%), followed by bioreactors (22%),
phytoremediation/rhizoremediation (22%), composting (13%), biopiles
(4%), enzyme-mediated bioremediation (2%), vermiremediation (2%), and
others (2%) (Kuppusamy et al., 2017). Moreover, the second most
attractive integrated methods are applied in the subsequent order, i.e.,
biological–biological (42%), chemical–biological (27%),
physical–chemical (21%), physical–chemical–biological (5%), and
thermal–chemical methods (5%) (Kuppusamy et al., 2017). Microbial PAH
remediation (bioaugmentation and biostimulation) deals with separate or
combined application of specific microbes such as bacteria, archaea,
fungi, and algae. However, bacteria- and fungi-assisted degradation has
been widely studied.
Bacteria
Bacteria have unique
metabolic versatility for degradation of PAH pollutants (Ma and Zhai,
2012). During bacterial aerobic PAH degradation, the oxygen works as the
final electron acceptor and also as a co-substrate for the
hydroxylation and oxygen-mediated cleavage of the aromatic ring (Chen et
al., 2016), whereas bacterial anaerobic PAH degradation utilizes an
entirely diverse approach to break and open the aromatic ring depending
on the reductive reaction type and alternative final electron acceptors
(Ghosal et al., 2016; Dhar et al., 2020). Chiefly, the bacteria perform
aerobic PAH degradation using oxygenase-facilitated metabolism
(comprising monooxygenase and dioxygenase enzymes). The first step in
the aerobic PAH degradation is the hydroxylation of the aromatic ring
through dioxygenase enzymes and formation of the cis-dihydrodiol, which
ultimately oxidized to diol intermediates with the help of dehydrogenase
enzymes.
These diol intermediates finally break open through the
action of intra diol or extra diol ring-breaking dioxygenases via
either ortho-cleavage or meta-cleavage pathway, able to form
intermediates such as catechol, gentisic acids, and protocatechuic acid,
which finally transform to tricarboxylic acid (TCA) cycle intermediates
(Mallick et al., 2011). Dioxygenase is the multi-enzyme complex usually
comprising of reductase, ferredoxin, and terminal oxygenase subunits
(Mallick et al., 2011; Ghosal et al., 2016; Wu et al., 2020). Bacteria
also strategize PAH degradation by the cytochrome P450-assisted pathway
with the formation of trans-dihydrodiols or anaerobically under nitrate-
and sulfate-reducing conditions (Lu et al., 2011; Mallick et al., 2011;
Yang et al., 2020). Although aerobic PAH degradation is conventional
and preferable, anaerobic PAH degradation is gaining more attentions
nowadays due to the presence of anoxic conditions in diverse
environmental niches such as phreatic zone, deep aquatic sediment, and
water-flooded soil (Ghosal et al., 2016; Dhar et al., 2020).
The
aerobic and anaerobic bacterial species have been reported extensively
in the literature for the degradation of LMW and HWM PAHs through pure
cultures, consortia, and mixed bacterial culture approaches (Table 2).
The enhanced or complete PAH degradation can be achieved by mixed
bacterial cultures and bacterial consortia as results of collaborative
catabolic activities of participants and possibly presence of diverse
degradation pathways. Therefore, most of the recent studies emphasized
on mixed bacterial culture- and consortia-assisted PAH degradation
(Vaidya et al., 2018; Haleyur et al., 2019; Patel et al., 2019).
Degradation by immobilized bacteria and genetically modified bacteria is
also a considerable approach (Peng X. et al., 2018). One of the major
difficulties for degradation in soil/sediment is a dispersion of
inoculum; it is easy for surface soil, however, challenging for
subsurface soil due to limited microbial transport as cells adhere
strongly to soil organic matter.

The immobilization of
delivering inoculum microbes can serve the solution by increasing shelf
life and activities of microbes in the soil system (Mrozik and
Piotrowska-Seget, 2010). Huang et al. (2016) reported enhanced pyrene
and indeno[1,2,3-cd]pyrene degradation (71 and 81%) in
petroleum-contaminated soil using immobilized Pseudomonas taiwanensis
PYR1 and Acinetobacter baumannii INP1 on cinder beads. Immobilization
provides biological stability to inoculum microbes, protection from
suboptimum substandard environmental conditions, and reduced competition
with indigenous microbes (Mrozik and Piotrowska-Seget, 2010). Apart
from mesophilic bacteria, bacterial extremophiles such as halophilic,
acidophilic, and thermophilic have also been reported for PAH
degradation (Table 2). Application of thermotolerant and thermophilic
bacteria for PAH degradation is beneficial, as elevated temperature
causes increased diffusion of PAHs by decreasing viscosity, ultimately
increasing the bioavailability of PAHs (Mehetre et al., 2019). Over the
last decade, bacterial community analysis (Muangchinda et al., 2018;
Yang et al., 2020), biochemical pathways in bacteria for PAH degradation
(Chen et al., 2016; Vaidya et al., 2017), degradation-associated
bacterial genes (Peng T. et al., 2018; Sangkharak et al., 2020), enzyme
systems (Chen et al., 2016; Wu et al., 2020), and gene regulation of PAH
degradation processes (Kan et al., 2020; Wu et al., 2020) have been
researched enormously.
Archaea
Extreme environmental
habitats, particularly saline regions, are most vulnerable to petroleum
pollution due to their close connection with oil industries, which
mostly release many pollutants, including PAHs, and demand extremophiles
rather than conventional microorganisms for bioremediation (Dastgheib
et al., 2012). Over the past few years, archaea have drawn the attention
of researchers for PAH bioremediation, although few research studies
have been reported (Table 2). The degradation pathways and mechanisms
behind bioremediation via archaea have not been extensively studied like
bacteria (Khemili-Talbi et al., 2015). Khemili-Talbi et al. (2015)
isolated biosurfactant-producing halophilic arhaeon Natrialba sp. C21
from oil-polluted saline water for degradation of phenol, naphthalene,
and pyrene at very high salinity conditions (25% NaCl). They also
attempted to find the degradation pattern via enzyme assays such as
catechol 1,2-dioxygenase, catechol 2,3-dioxygenase, protocatechol
3,4-dioxygenase, and protocatechol 4,5-dioxygenase. The maximum activity
of catechol 1,2-dioxygenase indicated that degradation occurred via the
ortho-cleavage pathway.
Fungi
Mycoremediation of PAHs has
been widely reported in the past several years with numerous fungal
species. Unlike bacteria, all fungi do not utilize PAHs as a sole source
of carbon; rather, they co-metabolize the PAHs and generate a range of
oxidized products including CO2. The fungi execute monooxygenase
enzyme-mediated PAH degradation (Gupta and Pathak, 2020). Mainly two
types, i.e., ligninolytic fungi (white-rot fungi) and non-ligninolytic
fungi, have been reported in the literature for LMW and HMW PAH
bioremediation (Table 2). Ligninolytic fungi produce enzymes such as
lignin peroxidase, manganese peroxidase, and laccases for degradation of
lignin present in the wood and simultaneously oxidize the PAHs and
convert into diphenol intermediates that eventually oxidize into
quinones (Aydin et al., 2017). Ligninolytic enzymes generate
water-soluble polar products after catalytic cleavage of aromatic
compounds, which are eventually available for fungal metabolism and soil
microflora present in the vicinity (Gupta and Pathak, 2020).
On
the other hand, non-ligninolytic fungi produce cytochrome P450
monooxygenase-like enzymes, which oxidize the PAHs and lead to form
arene oxide and water; further, arene oxides through non-enzymatic
rearrangement form phenols, which conjugate with xylose, gluconeric
acid, and glucose (Cerniglia and Sutherland, 2010; Ghosal et al., 2016).
Some fungal species are also capable of producing biosurfactants in
order to overcome the hindrance of less soluble HMW PAHs, which resulted
in better degradation (Ojha et al., 2019). Limited studies have been
reported on the mechanisms and pathways involved in the breakdown of
PAHs through mycoremediation (Aydin et al., 2017; Agrawal et al., 2018).
Direct fungi application in the field has many limitations including
inadequate biomass growth, huge biomass handling difficulties, lack of
application methodologies, and bulk degrading enzyme production, which
can be overcome by oxidative fungal enzyme-mediated PAH bioremediation
(Harms et al., 2011).
Algae
Algae, the primary producers
in coastline and estuarine ecosystems, may have a significant role in
PAH bioremediation within aquatic ecosystems. Alga-mediated effective
PAH removal occurs through cellular biodegradation and/or
bioaccumulation (Ke et al., 2010). PAH biodegradation employs both
monooxygenase and dioxygenase enzymatic pathways and produces
hydroxylated and dihydroxylated intermediates, respectively, depending
on the algal type (Chan et al., 2006). Microalgae (Cyanobacteria) are
freshwater unicellular green alga, have gained huge attention for its
ubiquitous occurrence, easy to propagate, and most prominent efficiency
of degrading HMW PAHs (Ke et al., 2010; De Llasera et al., 2016). Few
reports on alga-based PAH bioremediation are listed in Table 2. Many
alga-based PAH removal studies at the laboratory or microcosm scale have
been reported in the literature, although large- or field-scale
alga-mediated PAH remediation remains to be uncovered and requires
scientific attention to develop successful strategies.
Co-cultures
Co-culturing
approaches such as bacterial–fungal co-cultures, fungal–algal synergy,
and bacterial–algal synergy are proven as the most efficient bioremedial
approaches at the laboratory as well as large-scale applications
(Sharma et al., 2016; Subashchandrabose et al., 2019; Table 2). During
aerobic degradation, algae supply oxygen to enhance degradation. The
bacterial–algal synergy is more advantageous over bacterial consortia
and bacterial–fungal co-cultures because algae provide various extra
polymeric and lightweighted compounds (consist of lipids, proteins,
nucleic acids, fermentation products, etc.), which promote bacterial
and/or fungal growth and thus enhance PAH degradation (Kuppusamy et al.,
2017).
Microbial Enzyme-Mediated Bioremediation
Microbial
enzyme-mediated bioremediation involves the use of isolated enzymes
from bacteria, fungi, and other living organisms for PAH removal. The
enzymatic action is extremely efficient and selective due to higher
reaction rates and the capability to catalyze reactions at a wide range
of temperature and pH. Oxygenase, dehydrogenase, lignin peroxidase,
manganese peroxidase, laccases, and phenoloxidases are enzymes
responsible for PAH oxidation as mentioned in above subsections (Mohan
et al., 2006). The oxidative enzymes from fungi are more efficient
because they are less substrate-specific enzymes (Harms et al., 2011;
Gupta and Pathak, 2020). Zhang et al. (2020) isolated novel manganese
peroxidase gene from Cerrena unicolor BBP6 and cloned into Pichia
pastoris, which had various dye-decolorizing ability along with 80 and
91% of fluorene and phenanthrene degradation activity within 24 h, and
the highest recombinant enzyme expression was 154.5 Unit.L–1. The only
drawback of this method is cost related to production, extraction, and
purification of enzymes (Kuppusamy et al., 2017).
Strategies for Polycyclic Aromatic Hydrocarbon Bioremediation
Land
farming is a cost-effective and safe treatment for polluted land, in
which the native microbiome at a polluted site is stimulated for PAH
degradation via improving aeration, moisture, and nutrient levels so
that the connection of microbes is improved with pollutants and
nutrients (Agnello et al., 2016; Kuppusamy et al., 2017). The reduction
rate is much higher for LMW PAHs (2–3 rings) than HMW PAHs (4–6 rings),
and this method is applied usually for a thin layer of land surface (Das
and Das, 2015; Silva-Castro et al., 2015; García-Sánchez et al., 2018).
This simple method requires less maintenance, nearly no cleanup
obligations, and slight monitoring efforts. Limitations are slow
degradation rate after initial rapid degradation rate due to the
concentration gradient of pollutants, affected only superficial 10–35-cm
accessible soil layer, and largely influenced by surrounding
uncontrollable and unintentional conditions like heavy rainfall (Gan et
al., 2009).
Natural attenuation method enhances the degradation
capacities of innate microbiome by improving aeration, moisture, and
nutrient levels. If natural attenuation is performed on polluted land,
then it is a good example of land farming method. Chikere et al. (2017)
reported 98% total petroleum hydrocarbon and 85% poly aromatic
hydrocarbon degradation by enhanced natural attenuation in crude
oil-polluted field-scale bioremediation after. The enhanced natural
attenuation was processed by nutrient addition (N:P:K ratio 2:1:1),
tilling, periodic water irrigation, and intermittent turning of soil to
make sure there was uniform aeration (Chikere et al., 2017).
Biostimulation
is a remediation method in which the activities of indigenous microbes
can be encouraged by the addition of nutrients (N,P,S, and K), slow/fast
releasing fertilizers, organic wastes, humic acid, and/or terminal
electron acceptor. It is basically used to overcome limitations of
microbial growth and activities. Different combinations of macro- and
micro- nutrients are used to enhance PAH degradation (Das and Das,
2015). Patel et al. (2019) tested NPK fertilizer, urea fertilizer, and
AS fertilizer as biostimulating agents to enhance phenanthrene and
fluoranthene degradation by mixed bacterial cultures. Biostimulation can
also be performed through an adaptation approach in which high
pre-exposure of target pollutants are applied for adaptation of
selective organisms having the capacity to survive and utilize target
pollutants (Mohan et al., 2006).
A new era of nanobiotechnology
leads to the development of a more competitive biostimulation approach
for rapid PAH remediation based on the use of nanofertilizers and
nanominerals, which enable broader distribution of nutrients in deeper
soil (Kuppusamy et al., 2017). A time interval study conducted by Bianco
et al. (2020) on the effects of anaerobic biostimulation such as
digestate, fresh organic fraction of solid municipal waste, and
combination of micro-/macronutrients (ratio of soil and biostimulants
was 10:1) on the degradation of the four PAH mixture (200 mg.kg–1 of
anthracene, phenanthrene, pyrene, and fluoranthene) in marine sediment
at 37°C and 130 rpm confirmed biostimulation efficiency for PAH
degradation (55%) compared to control without any supplementation (12%).
The application of digestate and organic waste as biostimulants during
degradation signifies the economic perspective as well as encourages the
renewable remediation strategy (Bianco et al., 2020). Blood meal is a
dark-colored complex non-toxic liquid of animal origin, which acts as a
slow releasing fertilizer and is rich with lysine, valine, leucine,
tryptophan, and histidine. Recently, biostimulation using blood meal
along with weekly soil plowing was studied for in situ bioremediation of
dichlorodiphenyltrichloroethane (DDT)- and PAH-polluted farmland soil
(Wang et al., 2017).
Composting is one of the most preferable and
cost-effective remediation methods for pollutant degradation in soil,
which improves soil organic content and soil fertility, and it is one
type of biostimulation in which organic content is added (Chen et al.,
2015). Composting remediation is more successful for 3- and 4-ring PAHs
than 5- and 6-ring PAHs, as higher ring PAHs may negatively affect the
microbial activities of compost and their natural bioavailability was
low (Gan et al., 2009; Guo et al., 2020). The compost bulking agents
such as spent mushroom, soot waste, agricultural wastes, maple leaves,
cow manure, pig manure, activated sludge, etc., can be used in PAH
degradation that support the enhancement of microbial population and
raise the required temperature for degradation (Mohan et al., 2006;
Shah, 2014; Das and Das, 2015). Guo et al. (2020) studied biodegradation
of PAHs in polluted sewage sludge by a co-composting method using green
forest waste. The experiments were performed with three different
rations of sewage sludge and green forest waste. PAH degradation (75.2%)
was highest in ratio 3:2, followed by ratio 3:1 (70.7%) and ratio 3:3
(62.4%) after 50 days of composting in compost windrows (1.5 m width ×
1.2 m height × 10 m length).
Bioaugmentation is the introduction
of inoculum of pollutant-degrading single microorganisms or group of
microorganisms to achieve optimum degradation and sometimes to improve
the catabolic capacities of indigenous microbes (Das and Das, 2015). It
is effective, rapid, easily publicly adaptable, easily applicable, and
versatile alternative for PAH degradation; nevertheless, unpredictable
(Kong et al., 2018). Application of the bioaugmentation strategy for PAH
degradation may include bacteria, archaea, fungi, and algae as pure
cultures as well as mixed cultures; detailed description is presented in
the section Microbial Remediation of Polycyclic Aromatic Hydrocarbon
Pollution (Ghosal et al., 2016). The degradation of PAHs by
microorganisms occurs in the presence of oxygen and in the absence of
oxygen, which are called aerobic degradation and anaerobic degradation,
respectively. In anaerobic biodegradation, microbes use other substances
such as nitrate, sulfate, iron, manganese, and carbon dioxide as
electron exchanger during degradation and produce carbon dioxide and
methane as the final products. Anaerobic biodegradation is helpful to
remediate the deep underground soil where oxygen is absent or very low
(Gan et al., 2009).
Bioreactor is an ex situ controlled system
for efficient PAH degradation; addition of non-ionic surfactants,
bioaugmentation with useful microbes, and/or biostimulation with
additional nutrients enhance PAH bioremediation process in bioreactors
(Mohan et al., 2006). Soil column and soil slurry bioreactors degrade
effectively the soil-bound contaminants under controlled and optimized
conditions. The continuous fed batch reactors (anaerobic-anoxic-aerobic,
5 L each) were proved to be potential for 300 mg.L–1 of naphthalene
degradation (99%) in influent wastewater from coke oven industry along
with sulfate and ammonical nitrogen as biostimulants and cow dung slurry
as inoculum by Yadu et al. (2019). Forján et al. (2020) designed a
pilot- scale soil slurry bioreactor for PAH-polluted factory soil in
which dissolved oxygen (8 mg/L), pH (∼8), and temperature (28°C) probes
were constantly controlled. Soil slurry bioreactor was prepared by
combined approach of biostimulation (C:N:P ratio of 100:10:1) and
bioaugmentation using Rhodococcus erythropolis, which reported 89.3,
79.7, 72.0, and 82.1% degradation of 2-ring, 3-ring, 4–6-ring, and total
PAHs, respectively, after 15 days of bioreactor process (Forján et al.,
2020).
Phytoremediation is an in situ method in which the plants
are used to remove PAHs or to convert them into less harmful components
in soil, sediment, surface water, and groundwater (Das and Das, 2015).
Plants remediate the organic pollutants by different mechanisms such as
phytoextraction (withdrawal of pollutants from soil),
phytovolatilization (atmospheric release of volatile pollutants from
soil via plant organs), and phytodegradation (degradation of pollutants
by enzymes released from plant and/or plant-associated microbes)
(García-Sánchez et al., 2018). Plants help in soil aeration by
increasing permeability and by cracking soil masses, which favor PAH
aerobic biodegradation (Gitipour et al., 2018).
During
phytoremediation, plants resist easily a range of environmental assaults
due to their sessile characteristic. Plants are selected ideally based
on their quality to grow at a polluted site and growth time, biomass
productivity, ability to support active soil microbial population,
capability to degrade pollutants, and capability to adapt to
environmental conditions (Cook and Hesterberg, 2013). Economic viewpoint
suggests phytoremediation with grass is preferable due to less
maintenance, low nutrient requirements, robust growth, tolerance for
sought, acidic and, cold conditions, and their very fibrous root system,
which may help enhance soil microbial activities (Gan et al., 2009;
Cook and Hesterberg, 2013).
He and Chi (2019) investigated
phytoremediation capabilities of two submerged aquatic plants,
Vallisneria spiralis and Hydrilla verticillata, in PAH-polluted
sediments at pilot scale. The experiment was conducted for 108 days, and
results indicated that dissipation of phenanthrene and pyrene was
highest in sediment planted with V. spiralis (85.9 and 79.1%), followed
by sediment planted with H. verticillata (76.3 and 64.6%) and unplanted
sediment (76.3 and 64.6%). Higher dissipation of phenanthrene and pyrene
in planted sediments was due to plant-supported biodegradation and
plant uptake (He and Chi, 2019). Phytoremediation of soil polluted by
fly ash PAHs using willows of Salix × smithiana Willd (checked) was used
to remove 50.9% PAHs after 3 years of treatment (checked), which was
higher as compared to 9.9% ash PAH removal by natural attenuation in
soil (Košnáø et al., 2020).
Rhizoremediation is one specific
subset of phytoremediation, in which plant-associated rhizosphere
microorganisms are used for treatment of polluted soils (Das and Das,
2015). Rhizoremediation is more intensive for PAH degradation and a key
of successful rhizoremediation is dependent on the appropriate
partnership of plant and microbes that have degradation capabilities
(Agnello et al., 2016; Eskandary et al., 2017). Plants provide the huge
root surface area for microbial growth and remediate pollutants
approximately 10–15 m deep in the soil (Bisht et al., 2015). In
rhizoremediation, plant roots supply the nutrients for growth and
activities of PAH-degrading microbes in the form of carbohydrates, amino
acids, flavonoids, and organic acids, whereas microbes compensate by
supporting the plants to conquer against stress generated due to
pollutants and reduce the phytotoxicity (Bisht et al., 2015; Eskandary
et al., 2017). Kong et al. (2018) conducted field-scale PAH degradation
study (3 m × 1.2 m, 0.4 m depth, and 5 tons soil) for 175 days in aged
polluted soil of 50-year-old coking plants.
Comparison of four
different methods indicated that microbe-associated phytoremediation
(Rhodococcus ruber Em1 associated with Orychophragmus violaceus) was
superlative among natural attenuation, bioaugmentation (Rhodococcus
ruber Em1), and phytoremediation (Orychophragmus violaceus). R. ruber
Em1 combined with O. violaceus significantly enhanced the removal of 16
PAHs, 54% as compared to 18, 30, and 36% in other methods. The removal
of HMW PAHs with 4–6 rings were much greater by microbe-associated
phytoremediation methods (55%) as compared to natural attenuation (10%)
and phytoremediation (20%) (Kong et al., 2018). García-Sánchez et al.
(2018) also compared four different PAH bioremediation approaches via
pot experiments with 5 kg of aged polluted soil for 180 days. They found
a microbe-associated phytoremediation approach using maize plants along
with white rod fungi and indigenous microorganisms as the most
beneficial for removal of LMW, HMW, and total 16 PAHs as compared to
other approaches, i.e., natural attenuation, myco-augmentation using
white rod fungi Crucibulum leave, and phytoremediation using maize
plants (García-Sánchez et al., 2018).
The advantages of
phytoremediation and rhizoremediation as compared with other approaches
are that they preserve the natural conditions of the soil, energy is
derived primarily from sunlight, high level of microbial biomass in the
soil can be achieved, and both are cost-effective and
environment-friendly methods. The major drawbacks of both methods are
the site where plants cannot grow, large land requirement, limited
remediation depth, only applicable for low-level polluted site (plant
tolerance level), highly dependent on climate and seasonal conditions,
disposal of accumulated PAHs from plant parts, unknown effects of
biodegradation products, risk for pollutants to enter the food chain,
and uncertainty in treatment duration prediction (Gan et al., 2009;
Bisht et al., 2015; Gitipour et al., 2018).
Vermiremediation is
used as individual and combined with microbes or plants for PAH removal
from fine soil (pores size < 0.1 μm). PAHs in pores of fine soil are
not bioavailable and bioaccessible for degrading bacteria (size 1–10 μm)
and plant root hairs (size 15–17 μm). During vermiremediation,
burrowing actions of earthworms enlarge the soil pore size; therefore,
degrading microbes and plant root can penetrate into the soil, able to
grow and finally able to degrade hidden PAHs (Kuppusamy et al., 2017).
Earthworms also remove PAHs from the soil by either dermal absorption or
intestinal digestion that biotransform or biodegrade into harmless
compounds (Sinha et al., 2008). Benefits of vermiremediation include
improvement of physical/biological soil quality, excretion of nutritive
constituents as vermicasts, and proliferation of beneficial soil
microorganisms (Rorat et al., 2017). Earthworms reproduce speedily using
less or no energy, which possibly enhance PAH removal in a short time
duration, proving vermiremediation to be very cost-effective,
eco-friendly, and sustainable (Sinha et al., 2008). The addition of
earthworms Eisenia andrei in sewage sludge bioreactor after
precomposting had led to higher PAH removal (86, 58, and 62% under three
different pre-composting processes) after 5 weeks (Rorat et al., 2017).
The only drawback of vermiremediation is that it is applicable for low
and medium polluted sites, where earthworms are able to survive and grow
(Kuppusamy et al., 2017).

Energy harvesting
https://en.wikipedia.org/wiki/Energy_harvestingEnergy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g. solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks.
Energy harvesters provide a very small amount of power for low-energy electronics. While the input fuel to some large-scale generation costs money (oil, coal, etc.), the energy source for energy harvesters is present as ambient background and is free. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment because of radio and television broadcasting.
Piezoelectric
The piezoelectric effect converts mechanical strain
into electric current or voltage. This strain can come from many
different sources. Human motion, low-frequency seismic vibrations, and
acoustic noise are everyday examples. Except in rare instances the
piezoelectric effect operates in AC requiring time-varying inputs at
mechanical resonance to be efficient.
Most piezoelectric electricity sources produce power on the order of
milliwatts, too small for system application, but enough for hand-held
devices such as some commercially available self-winding wristwatches.
One proposal is that they are used for micro-scale devices, such as in a
device harvesting micro-hydraulic energy. In this device, the flow of
pressurized hydraulic fluid drives a reciprocating piston supported by
three piezoelectric elements which convert the pressure fluctuations
into an alternating current.

Preparation on transparent flexible piezoelectric energy harvester based on PZT films by laser lift-off process
http://www.sciencedirect.com/science/article/pii/S0924424712006516
The piezoelectric energy generation properties of transparent flexible devices (TFD) based on PbZr0.52Ti0.48O3
(PZT) films, which were fabricated by laser lift-off (LLO) process,
were studied for a piezoelectric energy harvester. Through the
introduction of indium-tin-oxide (ITO) and polyethylene terephthalate
(PET) substrates, TFDs were implemented, respectively. The TFDs based on
PZT films generated an AC-type output signal and output power of
8.4 nW/cm2, at periodically bending and releasing motion. In
addition, inverted output signals were observed when the manufactured
TFDs were connected to the measuring equipment in reverse and were
bended to the reverse direction, demonstrating that the generating
signals originated from the piezoelectric effect of TFDs. The
experimental results clearly showed that the TFDs based PZT film have
potential for use in next generation of electronic devices applications
such as flexible devices, transparent electronics, and energy harvester.

that the laser-machining process did not have significant effect on the
electrical properties of piezoelectric material. The fabricated device
was tested in the low-frequency regime of 50 to 1000 Hz at constant
force of 8 g (where g = 9.8 m/s2). The device was found to
generate continuous power of 1.13 muW at 870 Hz across a 288.5 kOmega
load with a power density of 301.3 muW/cm3.

Energy-Saving Thermoelectric Material Made From Dirt
November 29, 2012
A team of researchers at Michigan State University have developed a new type of thermoelectric
material by using common materials found in dirt. The researchers
developed this material using what they know about tetrahedrites, one of
the most abundant minerals on Earth.
MSU Professor of Chemical
Engineering, Donald Morelli, and his team figured out how to synthesize
compounds that have the same chemical composition as natural minerals
and closely mimic tetrahedrites. By modifying the composition,
researchers have been able produce even more efficient thermoelectric
material.
Why is this important? Themoelectric energy needs to be
more efficient to be a viable energy source. For example, if
thermoelectric was more efficient, the heat generated by a car engine
that travels through the tail pipe could then be converted into actual
electricity. By tweaking the composition, researchers are coming closer
to making this a reality.

Magnetostrictive resonators as sensors and actuators
http://www.sciencedirect.com/science/article/pii/S0924424712007509
Two types of magnetostrictive resonators – magnetostrictive
microcantilever (MSMC) and magnetostrictive particle (MSP) – have been
introduced as sensor platforms. Their principles and advantages as
sensor platforms are discussed along with the materials selection. A
detailed and complete comparison between the MSMC and MSP is given. It
is concluded that for the resonators with the same size, an MSP exhibits
a higher sensitivity and has a much higher resonant frequency. For the
resonators with the same resonant frequency, MSMCs exhibit a much higher
sensitivity and have a much smaller size than MSPs. Using antibody as
the sensing element, MSP biosensors for in situ detection of Escherichia coli and Listeria monocytogenes
are developed and characterized. These biosensors exhibit a high
performance. For example, the MSP-antibody biosensors of
1 mm × 0.3 mm × 15 μm exhibit a detection limit less than 100 cfu/ml for
in situ detection of bacterial cell in water. A new type actuator is
introduced using MSPs. The MSP actuator is operated using AC magnetic
field with a frequency close to, but different than, its resonant
frequency. The MSP actuator exhibits an unlimited displacement, and its
moving direction is controlled by the operating frequency used.

Levitating Magnet May Yield New Approach to Clean Energy
http://engineering.columbia.edu/levitating-magnet-may-yield-new-approach-clean-energy
Achieving nuclear fusion in the laboratory has been a cherished goal of physicists and energy researchers for more than 50 years. That’s because it offers the possibility of nearly endless supplies of energy with no carbon emissions and far less radioactive waste than that produced by today’s nuclear plants, which are based on fission, the splitting of atoms (the opposite of fusion, which involves fusing two atoms together). But developing a fusion reactor that produces a net output of energy has proved to be more challenging than initially thought.

synthetic. This has great implications for the use of clean fuel cells.
The team, comprised of Russian, French and German scientists, have
been collaborating to create this process that can be possibly used in
fuel cells. The study was conducted at the Moscow Institute of Physics
and Technology, at the Laboratory of Functional Organic and Hybrid
materials.
Batteries produce energy by utilizing the reaction of oxidizing and
reducing agents. The batteries’ lifespan is complete when both the
agents are consumed. When an accumulator is used, electric energy can be
stored in packets.

Archaea (/ɑːrˈkiːə/ ar-KEE-ə; sg.: archaeon /ɑːrˈkiːən/ ar-KEE-ən) is a domain of single-celled organisms. These microorganisms lack cell nuclei and are therefore prokaryotic. Archaea were initially classified as bacteria, receiving the name archaebacteria (in the Archaebacteria kingdom), but this term has fallen out of use.
Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in a laboratory and have been detected only by their gene sequences in environmental samples. It is unknown if these are able to produce endospores.

______________
The Role of Methanogens in Waste Water Treatment
As
one of the most diverse groups of Archaea known to date, the
Methanogens represent the euryarchaeota order which gains energy via
methane production. The methanogens utilize the metabolic process of
methanogenesis, which is the methane production pathway that converts
carbon dioxide and other bacterial waste products into methane.
Methanogens have become the focus of recent literature due to their
large contribution to global methane emissions as well as their role in
wastewater treatment. Methane is a potent greenhouse gas that has a
global warming potential of 25 in a 100 year time frame and is estimated
to account for 20% of the total radiative forcing from all greenhouse
gases (Wang et al., 2011). The recent increase in methane emissions,
from natural systems such as wetlands as well as landfills and
agricultural cattle, has made understanding methanogens crucial to
global climate change. Although methane emissions have negative
environmental impacts, the use of methanogens can be use in reducing
wastewater and the pollution of water systems across the world.
Methanogens help break down organic material that would otherwise
pollute water sources and lead to environmental degradation. The
construction of wetland systems in developing countries has been adopted
as a low cost and highly effective method of reducing nutrient
concentrations and degrading organic compounds in agricultural as well
as urban wastewaters (Johansson, et al., 2004). The balance of these two
impacts is vitally important for the future.

Energy Metabolism during Anaerobic Methane Oxidation in ANME Archaea
2017 Mar 17
Abstract
Anaerobic
methane oxidation in archaea is often presented to operate via a
pathway of “reverse methanogenesis”. However, if the cumulative
reactions of a methanogen are run in reverse there is no apparent way to
conserve energy. Recent findings suggest that chemiosmotic coupling
enzymes known from their use in methylotrophic and acetoclastic
methanogens—in addition to unique terminal reductases—biochemically
facilitate energy conservation during complete CH4 oxidation to CO2. The
apparent enzyme modularity of these organisms highlights how microbes
can arrange their energy metabolisms to accommodate diverse chemical
potentials in various ecological niches, even in the extreme case of
utilizing “reverse” thermodynamic potentials.

Methanotrophs: Methane Mitigation, Denitrification and Bioremediation
16 February 2017
Abstract
Methanotrophs
are bacteria capable of using methane as a carbon source. They can
lower atmospheric methane emissions, remove N in environmental and
wastewater treatment systems and even transform organic pollutants in
soils. Methanotrophic methane mitigation technologies have been
demonstrated beyond the laboratories as adaptable field-scale systems
that may be engineered to meet site-specific climatic variations and
ensure minimal atmospheric methane emission. In agricultural sediments
and soils, methanotrophs sequester methane but are affected by
fertiliser applications, while in wastewater treatment systems they can
lower the costs associated with N removal. Finally, the methanotrophs
are particularly appealing as bioremediation agents in
methane-containing environments, as their primary enzymes have a broad
substrate range that can transform various hydrocarbons, including
aromatic compounds and halogenated aliphatics. These diverse bacteria
are an important global methane sink and this importance is set to
increase as anthropogenic emissions increase over the coming decades.

Catalytic combo converts CO₂ to solid carbon nanofibers while offsetting emissions
January 11, 2024
Scientists
at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory
and Columbia University have developed a way to convert carbon dioxide
(CO2), a potent greenhouse gas, into carbon nanofibers, materials with a
wide range of unique properties and many potential long-term uses.
Their strategy uses tandem electrochemical and thermochemical reactions
run at relatively low temperatures and ambient pressure.
As the
scientists describe in the journal Nature Catalysis, this approach could
successfully lock carbon away in a useful solid form to offset or even
achieve negative carbon emissions.
"You can put the carbon
nanofibers into cement to strengthen the cement," said Jingguang Chen, a
professor of chemical engineering at Columbia with a joint appointment
at Brookhaven Lab who led the research. "That would lock the carbon away
in concrete for at least 50 years, potentially longer. By then, the
world should be shifted to primarily renewable energy sources that don't
emit carbon."
As a bonus, the process also produces hydrogen gas (H2), a promising alternative fuel that, when used, creates zero emissions.

Why Solid Carbon is the Future of Energy Storage
Feb 22, 2024
Energy storage is a huge sector, and growing at a rapid pace - largely due to the mass rollout of renewable energy. Lithium-ion batteries have a part to play in all of this, but they come with their own set of problems, including cost and the use of rare earth materials. This is why I am so interested in thermal batteries - using heat to store energy instead of chemical bonds. Antora energy have an incredible new way of doing this with solid carbon blocks and thermo-photovoltaic panels. So, I got in contact with them!

A review of green remediation strategies for heavy metal contaminated soil
25 November 2020
Abstract
Heavy metals and metalloids can accumulate in soil, with potentially toxic effects to
human health and ecosystems, threatening the sustainable use and management of soil
resources. Although a number of remediation technologies, such as Solidification/
Stabilization (S/S), soil washing, electrokinetic remediation and chemical oxidation/
reduction can be applied for the immobilization, removal or detoxification of heavy
metals in soil, the environmental, social and economic impacts associated with these
conventional approaches hinder their overall sustainability. More attempts have been
made to maximize the ‘net environmental benefit’ in various ways, including recov-
ering resources, embracing nature-based solutions (NBS), and saving energy with
the emergence and development of the ‘green and sustainable remediation’ (GSR)
movement. This review critically discusses these green remediation strategies, and
the novel soil amendments being utilized in these sustainable approaches. Iron-
based amendments are the most promising candidates in green remediation due to
the highest stabilization performances for both oxyanions and metallic cations as
well as relatively low disturbance to soil. In comparison, waste-derived materials
suffer from risks of contaminant release in the long run, reducing the overall sustain-
ability despite their low costs. It has been found that phytoremediation and green
amendment- based S/S are typically the ‘greenest’ remediation strategies, but wise
decisions should be made on the basis of case-specific sustainability assessment re-
sults. Finally, it is proposed that integration of several green remediation techniques
may have a synergistic effect on remediation efficiency.

Organic Acids for the In Situ Remediation of Soils Polluted by Heavy Metals: Soil Flushing in Columns
April 2001
Abstract
To compare the soil remediation effectiveness of saltsof weak organic acids with strongchelating agents, three soils of different textures,all polluted by heavy metals, were washed in a column,at optimum pH, with salts of weak organic acids,namely, citrate, tartarate or oxalate + citrate orchelating agents (EDTA or DTPA). For the clay loam,Cr, Mn, Hg and Pb were removed by citrate andtartarate at levels of 43 to 45, 37 to 41, 91 to 92and 75%, respectively. EDTA and DTPA effectivelyleached only Pb after 20 pore volumes. For the loam,citrate leached 98 and 89% of Cd and Pb after 20 porevolumes, respectively, while tartarate leached out 91and 87% of Cd and Pb. EDTA and DTPA removed 93 to97% of these metals after 20 pore volumes. For thesandy clay loam, 84 to 91, 73 to 84, 56 to 70 and 72to 81% of Cd, Cu, Pb and Zn were removedrespectively, by citrate and tartarate. EDTA and DTPAremoved 93 to 97% of these metals after 20 porevolumes. An in situ soil remediation simulation wasalso tested using the sandy clay loam in a tub. After 12 hr of retention, the citrate solution washed 81, 82,73 and 90%, of Cd, Cu, Pb and Zn, respectively, aftersix pore volumes. EDTA and DTPA effectively removedall heavy metals, except for Hg, but also extractedlarge quantities of soil nutrients and pollute thesoil by being adsorbed on the soil particles. Thesalts of citrate and tartarate effectively removed theheavy metals from the three polluted soils whileleaching little macro-nutrients and improving soilstructure. Each soil reached C and B levels ofsoil-clean-up criteria after 10 to 20 pore volumes andwithin 10 to 15 hr of flushing.

Soil remediation time to achieve clean-up goals II: Influence of natural organic matter and water contents
2006 Jan 9
Abstract
This work reports a relatively rapid procedure for the forecasting of the remediation time (RT) of sandy soils contaminated with cyclohexane using vapour extraction. The RT estimated through the mathematical fitting of experimental results was compared with that of real soils. The main objectives were: (i) to predict the RT of soils with natural organic matter (NOM) and water contents different from those used in experiments; and (ii) to analyse the time and efficiency of remediation, and the distribution of contaminants into the soil matrix after the remediation process, according to the soil contents of: (ii1) NOM; and (ii2) water. For sandy soils with negligible clay contents, artificially contaminated with cyclohexane before vapour extraction, it was concluded that: (i) if the NOM and water contents belonged to the range of the prepared soils, the RT of real soils could be predicted with relative differences not higher than 12%; (ii1) the increase of NOM content from 0% to 7.5% increased the RT (1.8-13 h) and decreased the remediation efficiency (RE) (99-90%) and (ii2) the increase of soil water content from 0% to 6% increased the RT (1.8-4.9 h) and decreased the RE (99-97%). NOM increases the monolayer capacity leading to a higher sorption into the solid phase. Increasing of soil water content reduces the mass transfer coefficient between phases. Concluding, NOM and water contents influence negatively the remediation process, turning it less efficient and more time consuming, and consequently more expensive.

Remediation Strategies
Remediation
strategies for contaminated soil can be broadly classified as
biological, chemical, or physical (Table 16.2). Many are a combination
of more than one type, and can be applied either ex situ or in situ. Ex
situ methods involve excavating the soil from the impacted zone and
treating the soil either on or off site. In situ methods treat the
contaminated soil in place. Contaminated sites often have contaminated
surface and ground waters that may require different or complementary
remediation strategies.
Table 16.2. Common remediation strategies for contaminated soils
Type Category Common contaminants Location
Biological Bioremediation, land farming, engineered biopiles or windrows Petroleum hydrocarbons
Bioventing Petroleum hydrocarbons In situ
Phytoremediation (rhizodegradation, phytoextraction,
phytodegradation, phytostabilization, phytoextraction) Petroleum
hydrocarbons, other organic contaminants, metals Generally in situ
Slurry phase reactors or lagoons Various organics Ex situ
Chemical Chemical oxidation / reduction Organics, inorganics Either
Neutralization Acids, bases Either

Bioremediation
is a biological treatment that uses soil microorganisms to treat
contaminants. It can use natural biodegradation processes, or enhance
them by adding commercial or other microbial preparations
(bioaugmentation), or adding nutrients such as nitrogen or phosphorus
and/or electron acceptors such as oxygen (biostimulation).
Bioremediation strategies focus on microbial degradation of organic
contaminants, although microbial induced chemical changes of inorganic
chemicals can be considered bioremediation, such as converting more
toxic chromium to the less toxic chromium.
Bioremediation can be
applied in various technologies, such as landfarms, biopiles, or
engineered reactors. Bioventing is an in situ treatment that enhances
microbial degradation of contaminants through enhanced aeration in the
contaminated zone. Use of plants to remove (phytoextraction), stabilize
(phytostabilization), or destroy (phytodegradation) contaminants is a
biological treatment called phytoremediation. Rhizosphere bacteria can
play an important role in biodegradation of organic contaminants during
phytoremediation (rhizodegradation).
Chemical treatments can be
used to convert contaminants to non-hazardous or less toxic chemicals,
or to forms which are less mobile, more stable, or inert. Chemical
oxidation using hydrogen peroxide, ozone, or permanganate can destroy
compounds such PAHs, and is best for liquids such as ground water or
soil slurries. Chemical reduction can convert toxic chromium to less
toxic chromium and degrade some chlorinated organic solvents such as
trichlorothene. Neutralization involves adding materials to adjust the
pH of highly acidic or caustic soil.
Physical treatments use
properties of the contaminant or contaminated medium to separate or
immobilize the contaminant. Chemical additives can improve removal
efficiencies. In situ, soil vapour extraction creates a vacuum in the
vadose zone, draws vapours into an extraction well, then treats or
destroys them above ground. Soil flushing occurs in situ, where the
contaminated zone is treated with a solution, and mobilized contaminants
are brought to the surface for disposal, treatment, or re-circulation.
Treatment solutions can be water, basic, acidic, chelating or
complexing, reducing, co-solvents, or surfactants. Dual phase extraction
involves installation of piping to ground water and vacuum extraction
of water and organic contaminants such as petroleum hydrocarbons. Soil
washing is done ex situ and may involve separating soil fines (silt,
clay) from coarse material thereby reducing the total mass and volume
that needs to be treated.
Solidification and stabilization
prevent or slow release of contaminants from soil by treatment with
binding agents such as cement or asphalt. The soil may be treated with a
material that will reduce contaminant solubility and mobility. For
example, phosphate based materials often reduce mobility of lead, by
converting lead into insoluble lead phosphate compounds. Hydrogen
sulphide can convert many metals into insoluble respective pyrites.
Electrokinetic
separation sends a low intensity direct current through the soil to
separate metals, radionuclides, and organic contaminants. Positively
charged species migrate to the cathode, and negatively charged species,
such as inorganic and organic anions, migrate to the anode.
Thermal
treatments are mainly used to remediate organic contaminants. Thermal
desorption is typically ex situ, with heat applied to soil to evaporate
or vapourize contaminants which are collected, treated, or destroyed.
Temperatures of 90 to 320°C are required to treat volatile organic
contaminants such as fuel components, 320 to 540°C to treat
semi-volatile organics such as PAHs, PCBs, and lubricants. Incineration
involves heating soil ex situ to 870 to 1370°C to destroy organic
contaminants. Vitrification heats soil to 1400 to 2000°C to melt silica
and convert it to stable glass and crystalline solids. Heat may be
generated by electrodes and electrical resistance or plasma arc
technology. Organic contaminants are volatilized, trapped, and treated
or destroyed and inorganic contaminants, including radionuclides, are
encased.

Bioaugmentation as a strategy for cleaning up of soils contaminated with aromatic compounds
2009
Summary
The
contamination of soil with aromatic compounds is of particular
environmental concern as they exhibit carcinogenic and mutagenic
properties. One of the methods of their removal from soil is
bioaugmentation, defined as a technique for improvement of the
degradative capacity of contaminated areas by introduction of specific
competent strains or consortia of microorganisms. The efficiency of
bioaugmentation is determined by many abiotic and biotic factors
discussed in this paper. The first include chemical structure,
concentration and availability of pollutants as well as physico-chemical
properties of soil. In turn, among biotic factors the most important is
the selection of proper microorganisms that can not only degrade
contaminants but can also successfully compete with indigenous
microflora.
Several strategies are being developed to make
augmentation a successful technology particularly in soils without
degrading indigenous microorganisms. These approaches involve the use of
genetically engineered microorganisms and gene bioaugmentation. The
enhancement of bioaugmentation may be also achieved by delivering
suitable microorganisms immobilized on various carriers or use of
activated soil.
Introduction
Industrial production of
chemicals as well as their inappropriate use, improper disposal and
accidental leakage has resulted in contamination of many areas. Among
man-made substances that cause ecotoxicological problems are a variety
of aromatic compounds such as halogenated aromatic compounds, polycyclic
aromatic hydrocarbons (PAHs) and BTEX compounds (benzene, ethylbenzene,
toluene and three isomers of xylene). The main sources of these toxic
substances are oil refineries, gas stations, use of wood preservatives
and agrochemicals, petrochemical and pharmaceutical industries. The
presence of these chemicals in the environment poses serious risks to
human health due to their toxicity, mutagenic and carcinogenetic
properties and ability to accumulate through the food chain. Most
aromatic compounds are recalcitrant, persistent and remain in the
environment for long periods of time (Budavari 1996).
There are
many methods for the removal of these pollutants from soils. They
involve both physico-chemical and biological approaches. Although the
first ones are more effective than biological methods they are expensive
and require high energy demand and consumption of many chemical
reagents. This is a reason why use of microorganisms capable of
degrading toxic compounds known as bioremediation has become an
attractive technology (Hamdi et al. 2007). One of the in situ
bioremediation strategies is bioaugmentation, which improves the
biodegradative capacities of contaminated sites by introduction of
single strains or consortia of microorganisms with desired catalytic
capabilities. Moreover, genetically engineered microorganisms (GEMs)
exhibiting enhanced degradative capabilities encompassing a wide range
of aromatic hydrocarbons have also potential for soil bioaugmentation.
Its place among bioremediation categories is depicted in Figure 1.

A new approach to cleaning heavy metals out of soil
June 4, 2019
https://engineering.stanford.edu/magazine/article/new-approach-cleaning-heavy-metals-out-soil
When poisonous heavy metals like lead and cadmium escape from factories or mines, they can pollute the nearby soil.
With
no easy ways to remove these contaminants, fields must be cordoned off
to prevent these toxins from entering the food chain where they threaten
human and animal health.
According to the Environmental
Protection Agency, heavy metals have been found at thousands of
locations nationwide. While some have been cleaned up through a
combination of federal, state and private efforts, the need remains for
new technologies to address heavy metal contamination
Now a research team led by Stanford materials scientist Yi Cui
has invented a way to wash heavy metals from contaminated soils using a chemical process that’s a bit like brewing coffee.
As they describe
in
Nature Communications, the researchers started by rinsing contaminated
soil with a mixture of water and a chemical that attracts heavy metals.
When that mixture percolates through the soil, the chemical pulls heavy
metals loose. The team members then collected this toxic brew and ran it
through an electrochemical filter that captured the heavy metals out of
the water. In this way they cleansed the soil of heavy metals and
recycled the water and chemical mixture to percolate through more
contaminated ground.
“This is a new approach to soil cleanup,”
said Cui, who is a professor of materials science and engineering and
photon science. “Our next step is a pilot test to make sure that what
works in the lab is practical in the field, and to figure out how much
this process will cost.”
So far, his team has cleansed soils
contaminated with lead and cadmium, two prevalent and dangerous toxins,
as well as with copper, which is only dangerous in high concentrations.
Cui believes this process of chemical cleansing and electrochemical
filtering will work with other dangerous heavy metals like mercury and
chromium, but further lab experiments are needed to demonstrate that.

Remediation of cadmium-contaminated soil: GLDA-assisted extraction and sequential FeCl3–CaO-based post-stabilization
2023
Abstract
Cadmium (Cd) contamination of farmland soils is a growing concern because of its highly toxic impact on ecosystems and human health. Chelator-assisted washing and chemical immobilization are effective remediation strategies for Cd-contaminated soils. Ethylenediaminetetraacetic acid (EDTA) has traditionally been used for soil washing, but its persistence in the environment and subsequent toxicity have raised significant ecological concerns. Consequently, biodegradable chelators have gained increasing attention as eco-friendly alternatives to the persistent chelator, EDTA. Therefore, this study evaluated the performance and efficacy of three biodegradable chelators: L-glutamate-N,N′-diacetic acid (GLDA), methylglycine-diacetic acid (MGDA), and 3-hydroxy-2,2′-iminodisuccinic acid (HIDS) in comparison to EDTA for remediating a real Cd-contaminated agricultural soil. The influence of treatment parameters, including chelator variants, washing time, chelator concentration, solution pH, and liquid-to-soil ratio (L/S) on Cd extraction was studied and optimized to attain the maximum removal rate. Following chelator-assisted washing, the efficacy of a stabilization preference combining FeCl3 and CaO in reducing the leaching potential of residual Cd in chelator-washed soil residues was also investigated. GLDA demonstrated comparable Cd extraction efficiency to EDTA, and the Cd extraction efficiency was found to be positively correlated with the soil washing parameters. However, under the optimized conditions (chelator concentration: 10 mmol L−1; washing time: 3 h; solution pH: 3; L/S ratio: 10:1), GLDA exhibited a higher Cd extraction rate than EDTA or the other chelators. Furthermore, a post-treatment process incorporating FeCl3 and CaO substantially diminished the water-leachable Cd content in the resultant soil residues. The proposed remediation strategy, which combines chemically assisted washing and stabilization, could be a practical option for extracting bulk Cd from soil and reducing the leaching potential of residual Cd.

Remediation of lead-contaminated soil by washing with choline chloride-based deep eutectic solvents
2022
Introduction
Lead-contaminated soil has attracted much attention as a typical heavy metal contaminated soil (Landrot and Khaokaew, 2018, Sun et al., 2019). And the formation of lead-contaminated soil was mainly attributed from natural (Zhang et al., 2020, Zhang et al., 2020) and human activities (Wu et al., 2016, Yoo et al., 2016). Lead compounds will exist in the soil for a long time, and cause serious harm to human health (Wei and Yang, 2010). Lead poisoning in particular affects the normal development of children (Mathee et al., 2018). Therefore, the research on the lead-contaminated soil remediation methods is of great significance to human and environment (Huang et al., 2021).
The main remediation methods for heavy mental-contaminated soil mainly include engineering methods (Li et al., 2020), physical and chemical methods (Zeng et al., 2020, Zhao et al., 2020), and biological methods (Gidudu and Chirwa, 2020). Engineering methods mainly refer to the application of machinery to cover up or transfer contaminated soil to achieve the purposes of soil remediation. Engineering measures mainly include soil dumping, soil replacement, top soil removal, additional soil and deep ploughing, which are characterized by being relatively simple and stable, and especially widely used in the soil remediation. However, the use of engineering measures can result in the physicochemical changes in the soil (Zhang et al., 2020, Zhang et al., 2020). The physi-chemical remediation methods refer to the soil remediation by combining physics and chemistry (Zhao et al., 2021). And the physi-chemical remediation technologies mainly include electrokinetic remediation (Nasiri et al., 2020, Xu et al., 2020), solidification/stabilization (Han et al., 2020), soil improvement (Lu et al., 2020), and washing technologies (Park et al., 2021, Peng et al., 2021, Zhu et al., 2015). Although these technologies are simple and effective, they tend to be costly and can result in secondary pollution (Bolan et al., 2014). Chemical washing is also used for remediate contaminated soil with heavy metals. The inorganic acid (Luo et al., 2018, Xing et al., 2021) chelating agents, surfactants (Mao et al., 2015), organic acid (Cheng et al., 2020) and inorganic salts were used as chemical agents. And they were usually applied to remediate contaminated soil by heavy metals (Dermont et al., 2008, Hu et al., 2021). However, there is still a need to determine an effective and environmentally friendly chemical reagents for soil remediation (Ke et al., 2020, Li et al., 2021, Wan et al., 2021). Citric acid, oxalic acid and tartaric acid were usually combined with EDTA (Gluhar et al., 2020), ethylenediamine tetra (methylene phosphonic acid) and polyacrylic acid (Feng et al., 2020) used to extract heavy metals from the contaminated soil.
Deep eutectic solvents (DESs) are a novel liquid similar with ionic liquid synthesized by two or more compounds with different melting points (Almeida et al., 2020, Hayyan et al., 2010). Usually it can be synthesized by mixing hydrogen bond donor (HBA) with hydrogen bond acceptor (HBD) (Bi et al., 2020, Hayyan et al., 2013a). The functional DESs obtained through the mixing natural plant derivatives (citric acid, glucose and fructose) with choline chloride has been investigated previously (Hayyan et al., 2012, Hayyan et al., 2013b). And DESs are also considered to be a novel and green solvents due to their excellent properties negligible volatility, non-flammability, nontoxicity, biodegradability, and thermal stability (Tome et al., 2018, Warminska et al., 2021). Hydrogen bonding is a key process for the formation of DESs and allows the creation of supramolecular structures between components identified from nuclear magnetic resonance (NMR) analysis. DESs have been widely used in electrochemistry (Li et al., 2016), sewage treatment (Soylak and Koksal, 2019), dissolving metal salts (Habibi et al., 2013), and separating harmful metals from various substances (Altunay et al., 2020, Bakkar, 2014, Mukhopadhyay et al., 2016a), due to its low toxicity, biodegradability, simple preparation and low price (Abbott et al., 2007). Recent studies have found that DESs had achieved good results in remediating soil contaminated by heavy metals (Habibollahi et al., 2019, Matong et al., 2017, Mukhopadhyay et al., 2016a). DESs are easily degraded by environmental factors when they are in the natural environment (Tang et al., 2021, Warminska et al., 2021). However, DESs are with high viscosity, which results in that it is very difficult to be recycled after remediation. In our previous research, choline chloride with ethylene glycol and water to synthesize diluted DESs and combining with EDTA-2Na can remove more than 95% of lead from lead-contaminated soil (Huang et al., 2021). However, DESs are seldom directly used for the decontamination of polluted soil.
The present research synthesized DESs through the mixing of HBDs such as ethylene glycol, urea, propylene glycol, glycerin, and malonic acid with the HBA choline chloride. These DESs were used in the present research for the lead-contaminated soil remediation. The optimal HBD was determined by comparing Pb extraction rate among the different DESs used. In addition, the effects of influence factors such as temperature, liquid-solid (L/S) ratio, water-DESs volume ratio, stirring speed, and choline chloride-malonic acid (Ch-M) molar ratio on Pb extraction were investigated and response surface analysis was also conducted. Moreover, the analysis of the DESs and soil were conducted before and after remediation to characterize the reaction mechanism. Finally, in order to illustrate the practical feasibility of the proposed remediation technique, the cost and application in real contaminated soil had been analyzed.

Sample preparation and regents
Soil samples were taken from the top soil of cultivated in Shanghai,
China (31°12′N, 121°39′E). The soil samples were naturally dried and
passed through a 0.18 mm sieve before being stored. Determination of
lead content of soil samples was 22.87 mg·kg−1 (CHN, Ministry of Ecology and Environment, 2017). Then, 23.98 g Pb(NO3)2
was dissolved in water and mixed with 1 kg soil samples to prepare
lead-contaminated soil. After 60 days of solidification, the Pb
concentration in the simulated
DESs screening
Th Ch-M and soil reaction system was the lowest pH values among all the evaluated DESs of 1.32 (Table S2). In Fig. 2, the five DESs (Ch-U, Ch-E, Ch-P, Ch-M, and Ch-G) were diluted with water and the solutions were used as washing agents for screening. Besides for Ch-M, the other DESs have little effect on the removal of Pb from the contaminated soil. This result can be attributed to the fact that the extraction of Pb from soil is strongly dependent on the pH (Table S2) of a solution
Conclusions
The current research has confirmed that diluted DESs (Ch-M) can be used for lead-contaminated soil remediation. The viscosity and cost of Ch-M could be reduced though diluted with water, and FT-IR analysis confirmed the effectiveness of the method. According to the FT-IR and HRMS analysis indicated that the carboxyl groups and hydrogen bonds in Ch-M chelate, resulting in the dissolving of Pb(NO3)2 and the formation of [Pb‧Chcl‧COOH], [Ch‧Pb], and other complex ions.

Remediation of mercury contaminated soil, water, and air: A review of emerging materials and innovative technologies
2019
Abstract
Mercury
contamination in soil, water and air is associated with potential
toxicity to humans and ecosystems. Industrial activities such as coal
combustion have led to increased mercury (Hg) concentrations in
different environmental media. This review critically evaluates recent
developments in technological approaches for the remediation of Hg
contaminated soil, water and air, with a focus on emerging materials and
innovative technologies. Extensive research on various nanomaterials,
such as carbon nanotubes (CNTs), nanosheets and magnetic nanocomposites,
for mercury removal are investigated. This paper also examines other
emerging materials and their characteristics, including graphene,
biochar, metal organic frameworks (MOFs), covalent organic frameworks
(COFs), layered double hydroxides (LDHs) as well as other materials such
as clay minerals and manganese oxides. Based on approaches including
adsorption/desorption, oxidation/reduction and
stabilization/containment, the performances of innovative technologies
with the aid of these materials were examined. In addition, technologies
involving organisms, such as phytoremediation, algae-based mercury
removal, microbial reduction and constructed wetlands, were also
reviewed, and the role of organisms, especially microorganisms, in these
techniques are illustrated.

Advanced techniques to remove phosphates and nitrates from waters: a review
13 April 2021
Abstract
At
high levels, phosphates and nitrates from mineral fertilizers and
wastewaters are contaminating natural waters, leading, for example, to
eutrophication and death of many living species. This requires
remediation techniques such as physical, chemical, biological methods,
and nano-techniques. For instance, microbes such as Bacillus subtilis,
Pseudomonas, Achromobacter, Spirulina platensis and Chlorella vulgaris
allow denitrification and can remove 55% of phosphates. Removal can be
done also using adsorbents produced from wastes and bio-sorbents. Here
we compare the methods to remove phosphates and nitrates in waters.

Asymmetrical
alternating current electrochemically-mediated washing method for
sustainable remediation of Cr(VI)-contaminated soil
2022 May 6
Abstract
The
demands for genuine remediation of heavy metal contaminated soil have
triggered extensive studies in the soil washing method. However,
numerous soil washing methods show poor sustainability for target soil,
due to the tremendous cost, hidden secondary pollution and severe soil
deterioration. Here, an asymmetrical alternating current
electrochemically-mediated remediation platform (ACRP) is developed by
fabricating an amidoxime-functionalized electrode (Ami-electrode). The
real soil contaminated with 1200 mg/kg Cr(VI) is remediated efficiently
to less than safety level (30 mg/kg), meanwhile no exorbitant soil
nutrient loss is observed and no secondary pollution occurs.
Furthermore, the consumption of washing effluents for the ACRP method is
24 times lower than the traditional washing method. Ami-electrode with
asymmetrical alternating current promote the electrocatalytic efficiency
by inhibiting the Coulomb repulsion between Cr(VI) species and cathode.
With the aid of Ami-electrode and positive bias, Cr(VI) species in
effluents are adsorbed on chelating site. By subsequent negative bias,
Cr element is reduced and recycled in the less hazardous form of
amorphous Cr(III) hydroxide, and effluents are regenerate concurrently
in a cyclic system. Durability experiment and cost calculation verify
the exceptional sustainability and feasibility for remediation
practices. This work provides a sustainable remediation method for
Cr(VI)-contaminated soil, and then paves the way to develop
electrochemically soil remediation platform for practical applications.

Removal of heavy metal ions from wastewater: a comprehensive and critical review
08 July 2021
Magnetic adsorbents
Magnetic adsorbents are a specific material matrix that hosts iron particles (usually magnetic nanoparticles, such as Fe3O4). The base material could be carbon, CS, polymers, starch, or biomass. As illustrated in Fig. 2,
the adsorption process is affected by the magnetic field, surface
charge, and redox activity characteristics. They showed low-cost,
easy-synthesis, extraordinary surface charge, and reusability. Many
magnetic adsorbents were proposed in the literature, such as zero-valent
iron nanoparticles (ZVI NPs), iron oxides (hematite (α-Fe2O3), maghemite (γ-Fe2O3), magnetite (Fe3O4)),
and spinel ferrites. The mechanism and kinetics of the sorption process
rely on several parameters, such as surface morphology and adsorbent
magnetic behavior. They are also affected by experimental conditions
such as pH, irradiation time, adsorbent concentration, wastewater
temperature, and the initial dosage of pollutants. The presence of iron
particles in adsorbent is very efficient in metal ions removal from
effluent.
Some studies have focused on coating Fe3O4 particles for removing heavy metal ions. Co-precipitation, high-gravity technology, and grafting are the most commonly used methods. The grafting method was considered a preferable choice because it is flexible and straightforward. However, it strongly depends on the active hydroxyl on the surface of Fe3O4 particles and the number of active functional groups. The produced adsorbents were not adequately cyclic stable, which is a barrier facing the commercialization of this method. Additional details about different magnetic adsorbents can be found in Supplementary Table 5.
Biosorbents
The most recent research studies in using biosorption for wastewater treatment are listed in Supplementary Table 6. The presence of numerous functional groups (i.e., carboxyl, amino, hydroxyl, phosphate, thiol, etc.) on the surface expedite the biosorption process. Generally, the interaction between pollutants and the surface of biosorbent can occur through electrostatic interaction, aggregation, complexation/coordination, microprecipitation, ion exchange, reduction, or oxidation. The solution pH affects the biosorbent surface charge density and ionization of functional groups located on the biosorbent surface. When pH is low, cations are almost stable and can be bonded to the biosorbent surface. On the other hand, at higher pH values, the solubility of metal cations decreases with the possibility of a precipitation phenomenon.
The biosorbent amount is a vital factor affecting the removal efficiency due to offering more vacant biosorption sites. The biosorbent capacity could increase at higher temperatures due to decreased solution viscosity, reduction in Gibb’s free energy, and bond rupturing. These reasons increase the collision frequency (mobility and kinetic energy) between biosorbent and metal ions and enhance the biosorbent active sites, leading to a higher affinity. In turn, the bonding force between biosorbent and pollutants could decline at higher temperatures, and thus the biosorbent sorption uptake reduces. It was elucidated that the removal efficiency increases as the mixing agitation rate increases.
Metal-organic frameworks adsorbents
Metal-organic frameworks (MOFs) are generally synthesized via reticular synthesis in which metal ions are strongly bonded to organic linkers. Researchers proposed thousands of MOFs. It was noticed that most of the organic ligands used to form many MOFs are very expensive and toxic. Zirconium-MOFs family (such as UiO-66) is promising nanostructure materials for sorption applications due to the easy incorporation of functional groups and hydrolytic-thermal stability such as amine, carboxylic, hydroxyl, and oxygen or by using the cross-linking method. Composite-based MOF adsorbents could obtain further enhancement in the adsorption capacity of MOFs. Supplementary Table 7 lists the uptake of different MOFs towards several heavy metal ions in wastewater.
Despite the exciting features of MOFs and their good capability to remove heavy metal ions, they have micropores (i.e., tiny pores) inaccessible for some target metals. Also, most of them have low stability in water. Mn, Fe, and Cu have been used to form MOFs, but most of them resulted in poor chemical stability. Therefore, further research is still needed to tune the MOFs’ structure and scale up these materials to implement them into industrial wastewater applications. Moreover, different functionalization methods should be proposed and applied to enhance MOFs’ stability and sorption kinetics.
Membrane-based filtration and separation
Over
the years, technological advancement in membrane development has led to
an increase in the use of membranes for filtration and extraction of
heavy metal ions from wastewater. A simplified schematics for different
membrane-based filtration processes is illustrated in Fig. 3a–c, while
Fig. 3d demonstrates various pollutants that can be separated by
different membrane techniques.
Ultrafiltration
Ultrafiltration
(UF) is used at low transmembrane operating pressure (TMP). Because UF
membrane pores may be larger than the heavy metal ions, additives may be
bonded to metal ions to enlarge the size of the metal ions. Therefore,
micellar enhanced ultrafiltration (MEUF) and polymer enhanced
ultrafiltration (PEUF) are proposed.
MEUF is formed by bonding UF
and surfactant. MEUF has high flux and high selectivity, leading to
low-energy consumption, high removal efficiency, and less space demand.
MEUF is most suitable for wastewater whose heavy metals are in low
concentrations. In MEUF, a surfactant is mixed with wastewater in a
concentration above the critical micellar concentration (CMC). Beyond
CMC, surfactant monomers assemble and increase the creation of some
micelles in the solution. The surfactant contains a hydrophobic tail and
a hydrophilic head. The inner hydrophobic core of the micelles could
solubilize organic matters (having low molecular weight) as a
solubilizate, while the surface adsorbs counter metal ions on their
surface due to electrostatic interactions. Surfactants, whose electric
charge is the opposite of the metal ions, usually attain the highest
retentions. In this regard, polyelectrolytes (PE), cationic surfactants,
and anionic surfactants (e.g., sodium dodecyl sulfate (SDS)) are used
for effective heavy metals extraction.
A summary of different
studies on the MEUF process is given in Supplementary Table 8. The
performance of MEUF depends on several factors, including the added
solutes, type of surfactant, operating conditions, and kind of membrane
used.
PEUF is formed through the integration of UF and binding
polymers. The functional groups of the bonding polymers could be
sulfonate, phosphonic, carboxylated, or amine, and they are bonded via
chelating or ionic bonds58. PEUF are also known as polymer-supported,
complexation, polymer-assisted, size enhanced, and complexation enhanced
ultra-filtrations. While permitting water and un-complexed components
to permeate the membrane pores, the PEUF process blocks and extracts
polymer-bonded metal ions.
A summary of studies conducted on PEUF
is presented in Supplementary Table 9. PEUF shows effective polymer
bonding, effective extraction, ability to recover and reuse complexation
polymer of retentate, low-energy demands, and low-cost operation.
However, the choice of appropriate water-soluble polymer macro-ligands
remains the main challenge of developing this technology.
Nanofiltration
Nanofiltration (NF) is used to concentrate constituents whose molecular
weight is >1000 Da and remove solutes whose size of 0.0005–0.007 μm
with molecular weights >200 Da. Thus, the operating range of NF is between UF and reverse osmosis (RO) processes.
The NF membranes are composed of polymer composites of multiple-layer
thin-film of negatively charged chemical groups. Anti-fouling NF
membranes containing CeO2/Ce7O12 and PES were synthesized through phase inversion and used to extract Fe3+, Al3+, Co2+, Cd2+, Cu2+,
and humic acid from wastewater and reached extraction efficiency
between 94 and 98%. Other studies are presented in Supplementary Table 10.
Microfiltration
Microfiltration (MF) employs a microporous membrane to remove micron-sized particles, bacteria, viruses, protozoa, contaminants, pollutants, etc., from a solvent/fluid/solution60. MF process is also a low pressure-driven membrane process, whose membrane pores are in the range of 0.1–10 μm60. Some of the MF membranes are made of silica, ceramics, zirconia, alumina, PVC, polysulfone, PTFE, polypropylene, PVDF, polyamides, polycarbonate, cellulose acetate, cellulose esters, or composite materials. The commercial application of MF is widely found in pharmaceutical and biological industries. However, the application of the MF system may be found in particle removal of the rinse water in the semiconductor industry, sterilization of beer and wine, other juices and cider clarification, and wastewater treatment60. The application of MF in heavy metal removal has not drawn enough attention because of its low removal ability. However, it has been used by modifying membrane or chemical pre-treatment of the feed solution. Depending on the mode of application, the MF process is available in two main configurations: crossflow and dead-end. Some studies on MF are summarized in Supplementary Table 11.
Reverse osmosis
RO is a
pressure-driven separation process that employs a semi-permeable
membrane (pore size 0.5–1.5 nm) to allow only smaller molecules to pass.
RO process reverses the normal osmosis process by applying pressure
(20–70 bar) >the osmotic pressure of the feed solution. The molecular
size of the solutes blocked is usually in the range of
0.00025–0.003 μm60. RO process could extract 95–99% of inorganic salts
and charged organics60. RO process is compact and attained high
rejection efficiency. However, membrane fouling and degrading are the
major drawback of RO systems60. The RO separation process was used to
extract heavy metal ions, including Ni2+, Cr6+, and Cu2+ from
electroplating wastewater, with a removal efficiency of >98.7562.
Recently, RO has been used to purify industrial wastewaters from
coster-field mining operations located in Victoria-Australia with mean
extraction efficiency of 10%, 48%, 82%, 66%, and 95% for Fe3+, Zn2+,
Ni2+, As3+, and Sb3+ respectively63. Other studies on RO heavy metals
removal are summarized in Supplementary Table 12.
Forward osmosis
Forward
osmosis (FO) is an osmosis process that requires a membrane to balance
selectivity and permeated water flux51. In FO, a semi-permeable membrane
separates a feed solution from the draw solution, as shown in Fig. 3b.
The draw solution is usually at a higher osmotic pressure compared to
the feed solution. Due to the osmotic pressure difference between the
feed and draw solutions, water transports from the feed solution to the
draw solution, thereby keeping the rejected solutes on the feed side and
treated water on the draw solution64. FO does not require hydraulic
pressure; thus, it is energy-saving. FO process is also environmentally
friendly, easy cleaning, and low fouling; therefore, it is widely used
in wastewater treatment64. Nevertheless, FO has limitations, such as
draw solution re-concentration, membrane selection challenges, internal
and external concentration polarization65. Supplementary Table 13
summarizes the use of FO, including thin-film membranes.
Electrodialysis
Electrodialysis
(ED) is used to separates ions at the expense of electric potential
difference. ED uses a series of cation exchange membranes (CEM) and
anion exchange membranes (AEM), alternatively arranged in parallel, to
separate ionic solutes51. In the ED process, the anions pass through
AEM, while cations pass through CEM. In such a case, the treated stream
(diluate) is produced from half of the ED stack channels, while the
concentrated stream is expelled from the other half, as shown in Fig.
3c. ED offers high water recovery, no phase change, no reaction, or
chemical involvement66, and can operate over a wide range of pH values.
However, ED also exhibits membrane fouling, high cost of membranes, and
demand for electric potential.
ED has been used to separate Ni2+, Pb2+, and K+
from synthetic solution through a novel ED heterogeneous CEM
(consisting of 2-acrylamido-2-methyl propane sulfonic acid-based
hydrogel and PVC) to attain extraction efficiency of 96.9%, 99.9%, and
99.9% for Ni2+, Pb2+, and K+, respectively. A batch ED process was employed to recover Pb2+ and reached a maximum separation efficiency of ~100%. A pilot-scale ED system has also been used to extract Cu2+, Ni2+, and traces of Cd2+, Fe3+, Cr6+, and Zn2+, and exceeded 90% removal rate. As3+ and As5+ were removed from metallurgical effluent by ED and attained a removal efficiency of 91.38%.
Other membrane-based methods
Chemical-based separation
Chemical
methods for removing heavy metals from wastewater are mature and used
early. In this section, the chemical-based methods will be discussed,
including precipitation, coagulation-flocculation, and flotation.
Membrane distillation (MD) and liquid membrane (LM) are also used for wastewater treatment. MD is a hybrid thermally driven membrane separation process that consists of cold and hot compartments separated by a microporous hydrophobic membrane. MD allows only vapor to permeate its pores while blocking other molecules. MD exists in four configurations: direct contact MD, air gap MD, sweeping gas MD, and vacuum MD. MD process has been reported to achieve over 96% removal of Ca2+, Mg2+, Fe3+, and Fe2+, and more than 99% for As3+ and As5+.
On the other side, LM is made of a liquid phase or thin-layer organic phase, which acts as a barrier between two aqueous phases. LM is immiscible to the feed solution and retentate solution, and combined stripping and extraction processes in a single stage. LM is highly selective, relatively efficient, and can achieve specific molecular recognition. However, the membrane’s long-term stability is poor. LM process exists as a supported liquid membrane (SLM), emulsion liquid membrane (ELM), bulk liquid membrane (BLM), and polymer inclusion membrane (PIM). Among these types, the SLM process is an attractive alternative to traditional solvent extraction for heavy metal removal. SLM achieved a removal efficiency of 89% for Zn2+, Cd2+, Cu2+, and Fe3+.
Precipitation
Chemical
precipitation (the so-called coagulation precipitation) is broadly used
in industries and is considered one of the most effective and mature
methods. It changes the form of dissolved metal ions into solid
particles to facilitate their sedimentation. The reagent coagulation
(coagulant) precipitates metal ions by changing pH, electro-oxidizing
potential, or co-precipitation76. It is usually followed by the removal
of sediments. A simple schematic of the chemical precipitation process
is depicted in Fig. 4.
Hydroxide precipitation is broadly used
due to its relatively inexpensive, simple, and tunable pH77. It is
implemented by adding a hydroxide to the stirred wastewater to form
insoluble metal hydroxide precipitates. For example, a metal ion could
react with calcium hydroxide (lime) to produce metal hydroxide
precipitates and calcium ions as:
It was found that pH values of 9–11 improved this process efficiency.
However, a high pH value is considered a disadvantage of this method
since it requires a large dosage of precipitates. One of the most
effective hydroxide precipitates for treating inorganic effluents of
heavy metal concentration of 1000 mg/L is lime (CaO or Ca(OH)2). A summary of some hydroxide precipitation studies is presented in Supplementary Table 14. It can be seen that the majority of metals removed by this method are Zn2+, Cu2+, Ni2+, Pb2+, and Cr3+.
In addition to the need for the high dosage to get optimal pH, there
are some drawbacks, such as relatively large volumes of sludge leading
to dewatering, disposal issues, amphoteric, and the inhabitation of
metal hydroxide precipitation with the presence of complexing agents.
The
sulfide participation method distinguishes itself by higher removal
efficiency and lesser dissolved solids increment than the hydroxide
method. This method was reported to treat toxic heavy metal ions80.
Lower sulfide results in a higher zinc concentration in the effluent,
while higher sulfide leads to a malodor problem due to high residual
sulfide. Also, it could produce hydrogen sulfide gas which is malodorous
and toxic. For these reasons, the sulfide precipitation is recommended
to be executed at a neutral pH81. The metal sulfide precipitations could
follow Eq. (2) reaction,
Supplementary Table 15 summarizes
the metal ions removal using sulfite precipitations. The toxicity of
sulfide and its high cost are the most shortcomings.
As an
alternative method to hydroxide precipitation, carbonate precipitation
shows good effectiveness and optimum precipitation at lower pH values82.
It could be achieved using sodium carbonate or calcium carbonate. The
classical carbonates can be formed based on Eq. (3 and 4):
It
could have less sludge volume, but it could release CO2 bubbles and
needs higher reagents for efficient precipitation83. Supplementary Table
16 lists some studies concerning carbonate precipitation. It can be
seen that copper and manganese are the major metals removed by this
technology. Zinc and lead could also be removed efficiently.
Fenton reaction is usually used to improve the removal efficiency of the
chemical precipitation methods. The Fenton or Fenton-like oxidation is
used for the de-complexation of heavy metal complexes. However, the pH
is adjusted by the chemical precipitation mechanism (e.g., NaOH). Fenton
chemistry is not straightforward, and it is performed through numerous
reactions, depending upon various active intermediates, such as [FeIV O]2+ and hydroxyl radicals. The classical Fenton reaction is:
Fe3+-H2O2 (Fenton-like) and Fe0-H2O2 (advanced Fenton) are also represented as an alternative for Fe2+-H2O2. Additional detailed examples of using the Fenton-integrated chemical precipitation method are summarized in Supplementary Table 17.
Some metals are represented in small volumes in bulk wastewater, such as radionuclides. The removal of radioactive metals is listed in Supplementary Table 18.
Coagulation and flocculation
Coagulation is the destabilization of colloids by neutralizing the forces that keep them parted, while flocculation is the agglomeration of destabilized particles. Traditional coagulants are aluminum, ferrous sulfate, and ferric chloride, using to neutralization of ion charges. Flocculation bonds the particles forming large agglomerates with the help of a flocculant, such as polyaluminum chloride (PAC), polyferric sulfate (PFS), polyacrylamide (PAM), and other macromolecule flocculants. The PE were reported as one of the most practical flocculations, but the produced sludge might be toxic. The flocculants are generally not natural and non-biodegradable.
The process is illustrated in Fig. 5, including the sedimentation. Some weaknesses are toxicity and health hazardousness of inorganic coagulants, a large volume of sludge, selective for some metals and inefficient in emerging contaminants, increasingly effluent color, inefficient when using natural coagulants, and complex of scaling up. Supplementary Table 19 summarizes some of the studies conducted on coagulation-flocculation for heavy metal removal from different wastewater sources. The typical heavy metals removed by this method include Cu2+, Pb2+, and Ni2+. Other metals such as As2+, Se2+, Cr2+, Sb3+, Sb5+, Ag2+ could also be efficiently removed.
Flotation
Flotation
is used to remove various metal ions. The general schematic of the
flotation process is shown in Fig. 6. Dissolved air flotation, ion
flotation, and precipitation flotation were extensively studied. In the
dissolved air flotation, air (or gas) is fed to wastewater to generate
micro-bubbles that could attach the metal ions, developing lower density
agglomerates, leading to raising the flocs through the wastewater. The
accumulated slug at the top surface can easily be removed.
Electric-based separation
In
this section, different electrochemical methods (i.e., electrochemical
reduction (ER), EC, electroflotation (EF), and electrooxidation (EO)),
and ion exchange method are discussed.
Electrochemical treatment
In
an electrochemical system, oxidation is performed at the anode
(positive side), where electrons transfer to the cathode (negative
side), at which the reduction process occurs. These two chemical
reactions are called redox (reduction-oxidation), leading to water
purification through metal removal. For example:
Ion exchange treatment
The ion exchange method is a reversible chemical reaction used to
replace the undesirable metal ion with harmless and environmentally
friendly ones.
A heavy metal ion is removed from a wastewater solution by attaching it
to an immobile solid particle as a replacement with the solid particle
cation, as shown in Fig. 8.
The material of solid ion-exchange particles could be either natural,
e.g., inorganic zeolites, or synthetically produced, e.g., organic
resins. The ion-exchange method can remove target (some or all) heavy
metal ions, such as Pb2+, Hg2+, Cd2+, Ni2+, V4+, V5+, Cr3+, Cr4+, Cu2+, and Zn2+ from wastewater.
The ion exchange mechanism for metal removals can be explained in the
following reaction as the ion exchange particle having ion exchanger of M−EC+ (M− is the fixed anion and EC+ is the exchange cation; Na+ and H+ are frequently used as exchange cations) to exchange its cation (EC+) with the wastewater cation (WC+).
Photocatalytic-based separation
The photocatalytic process was reported as a simple process for wastewater treatment that uses light and semiconductors, such as titanium dioxide (TiO2). Three key steps are taken in this process: charged carrier photogeneration, charged carrier separation and diffusion to the photocatalyst surface, and redox reaction on the photocatalyst surface. The effluents of real soil washing wastewater were treated using an outdoor dual solar photocatalytic process of flat plate collector for the removal of 93.5% Cu2+, 99.6% Fe3+, and 99.4% Zn2+. A simulated ultraviolet (UV)–solar TiO2 photocatalysis has been used for the removal of ethylenediamine-N, N′-disuccinic acid (EDDS), and Cu2+ from wastewater (0.2 mM EDDS and 0.2–1.4 mM CuSO4) to obtain 100% conversion efficiency at 24% mineralization degree. In another study, maximum removal efficiencies of 41% Cu2+, 100% Fe3+, 100% Zn2+ and 100% EDDS were obtained from synthetic soil washing solution (3.6 × 10−1 mM EDDS, 8.0 × 10−2 mM Cu+2, 1.0 × 10−1 mM Fe+3 and 8.0 × 10−2 mM Zn+2).
Using visible light irradiation, a synthesized rhodium/antimony co-doped TiO2 nano-rod and titanate nanotube (RS-TONR/TNT) was used to extracts Pb2+, Cd2+, Cu2+, Zn2+, and organic pollutant from wastewater with 70 and 80% degradation efficiency for dye and Bisphenol A, respectively. The photocatalytic process using CeO2/BiOIO3 composites with Ce4+/Ce3+ redox centers was used to attain 86.53% Hg2+ removal efficiency under visible light absorption and photocatalytic activity. In an aqueous solution containing As5+ and Cr6+ (concentration of 0.10 mg/L), a synthesized 3D-Fe2O3 was used to achieve nearly 100% removal rates using solar light irradiation and photocatalytic activity. A fabricated CH-GEL/ZSPNC hybrid nanocomposite ion exchanger achieved 90% Ni2+, 94.9% Zn2+, 95% Mg2+, 100% Pb2+, 90.3% Cd2+, 88.9% Cu2+ and 84% Rhodamine-B (dye) extraction efficiencies using solar light.
A fabricated CS/silver bio-nano-composites (CS/PVDC/Ag) was utilized in photocatalytic oxidation process for 97% Cu2+, 88% Pb2+, 89% Cd2+ and 77% dye removal. Although this technology shows the in site generation of reactive radicals, no chemicals used, no sludge production, it has some drawbacks. It is still on a laboratory scale, low throughput, dependent on pH, and inefficient when different metals are present.

Soilless remediation of the fine carbonate-rich gold-copper mine tailings
21 August 2023
Soil remediation with minimum amendments is a good strategy for tailings disposal. Carbonate-rich gold-copper mine tailings occurring alongside the Yangzi River, China, were employed as the objective in this study. They showed the characteristics of fine particles and alkaline pH with high density and low nutrition. The amendments including bacterial fertilizer (BF), polymer, peat, straw, and compound fertilizer (CF) were used for soilless remediation on the tailings. Soil quality index (SQI) involved in tailing properties and growth characteristics of ryegrass was used to optimize the combination of amendments. The results showed that the optimum amendment combination was 0.2% BF + 0.6% CF + 0.2% polymer + 10% peat and 2% straw. Tailing nutrients such as soil organic matter (5.56%), available nitrogen (93.6 mg kg−1), available phosphorus (51.7 mg kg−1), available potassium (711 mg kg−1), and ryegrass exhibited the highest germination rate and biomass level under the optimal improvement conditions. Additional environmental assessments revealed that soilless treatment of the tailings helped to convert Cu, Zn, and As into residual forms. These findings show a good strategy for tailings soil improvement and provide a promising perspective of the soilless remediation for fine carbonate-rich metal tailings.

Soil Remediation by Agglomeration with Petroleum Coke
2004
Objective:
Contamination
of soils with crude or refined oil products is a problem often
associated with production, refining, and distribution of petroleum
hydrocarbons. Excavation and incineration of the soil is an effective,
but expensive, technology to remediate the contaminated soil.
Bioremediation
is useful as a polishing step, but conventional manual and mechanical
techniques must be used on heavy concentrations of oil. A hot water wash
is practical only for coarse soil contaminated with light oils. This
project proposes to use petroleum coke to remediate soil heavily
contaminated with crude oil or other high molecular weight hydrocarbons.
This project will treat oily soil with finely divided petroleum coke.
The bridging liquid (oil) will be supplied by the contaminated soil. The
agglomerated fine coke and contaminant oil will be floated and removed
leaving an oil-free soil. Our studies to date using fine coal have shown
this method capable of treating soils saturated with heavy hydrocarbons
(crude oil) with oil recoveries as high as 99.9%.
The coal and
oil were recovered as a high grade fuel. The Gulf Coast region, which
has a large amount of oil contaminated soil, or has the potential to
have large amounts of oil contaminated soil because of oil spills, does
not have an abundant quantity of the type of coal best suited to soil
remediation. Petroleum coke has this type surface and should be an
excellent choice as a remediation agent. Finely divided coal or, as we
hope, finely divided coke is a material that "scrubs" the oil from the
soil and lends an adsorbent surface for the oil. The benefits of this
project will be an economical and practical solution to a type of
contamination common to the Gulf Coast with a readily available
remediating agent. Because of previous work, The University of Alabama
has a fully equipped soil remediation laboratory to carry out this
investigation.

Recent advancements in hydrocarbon bioremediation and future challenges: a review
23 May 2022
Abstract
Petrochemicals
are important hydrocarbons, which are one of the major concerns when
accidently escaped into the environment. On one hand, these cause soil
and fresh water pollution on land due to their seepage and leakage from
automobile and petrochemical industries. On the other hand, oil spills
occur during the transport of crude oil or refined petroleum products in
the oceans around the world. These hydrocarbon and petrochemical spills
have not only posed a hazard to the environment and marine life, but
also linked to numerous ailments like cancers and neural disorders.
Therefore, it is very important to remove or degrade these pollutants
before their hazardous effects deteriorate the environment. There are
varieties of mechanical and chemical methods for removing hydrocarbons
from polluted areas, but they are all ineffective and expensive.
Bioremediation techniques provide an economical and eco-friendly
mechanism for removing petrochemical and hydrocarbon residues from the
affected sites. Bioremediation refers to the complete mineralization or
transformation of complex organic pollutants into the simplest compounds
by biological agents such as bacteria, fungi, etc. Many indigenous
microbes present in nature are capable of detoxification of various
hydrocarbons and their contaminants. This review presents an updated
overview of recent advancements in various technologies used in the
degradation and bioremediation of petroleum hydrocarbons, providing
useful insights to manage such problems in an eco-friendly manner.

How to Neutralize Cat Feces in Soil: All You Need to Know
Natural Solutions to Neutralize Cat Feces in Soil
Here's how you can naturally neutralize cat feces in soil:
Use earthworm composting bins to break down cat feces and organic
matter quickly. The worms do the work and produce nutrient-rich
castings.
Compost the cat feces with other organic matter before
applying it to the soil, but avoid fresh animal manure as it can have
harmful bacteria and parasites. Use a larger compost bin for better
breakdown.
Balance the high carbon content of cat feces by adding
extra nitrogen. This helps with efficient breakdown and prevents odors.
Keep the compost pile wet to create the right environment for decomposition. Moisture is vital for the breakdown process.
Let the composting process rest for at least two years before using it
to ensure complete breakdown and eliminate potential pathogens.
Properly composted cat feces can be excellent fertilizer for non-edible
plants because of its high levels of nitrogen, phosphorus, and
potassium.
However, don't use cat feces on food plants or crops as it can lead to illness from parasites and pathogenic bacteria.
To get rid of odor and bacteria in cat feces, mix lime, commercial
enzymes, vinegar, or baking soda with water. These methods are
effective.
Make the soil less hospitable to bacteria by adding
amendments like lime or sulfur. You can also use baking soda, coffee
grounds, leaves, or acid-loving plants to neutralize odor.
Be
cautious when handling lime as it can pose health risks. Additionally,
remember that cat feces might contain parasites that could contaminate
gardens and cause illness. It takes about a year for cat feces to
decompose, so dried feces may still attract bugs and emit unpleasant
odors.
Remember to prioritize safety measures and proper composting techniques when dealing with cat feces in soil.
Now that you know how to naturally neutralize cat feces in soil, I want to address another concern: eliminating cat urine odor.

How to Neutralize Cat Urine in Soil? All You Need to Know
https://icareforcats.com/how-to-neutralize-cat-urine-in-soil/
Here's what you need to do:
First things first, get rid of any visible cat urine. Grab some gloves
or a paper towel and scoop up those urine-soaked areas. Make sure you
dispose of it properly to avoid any more contamination.
Next,
flush the soil with water. This will dilute the urea and acid from the
cat urine and restore your soil's goodness. Pour plenty of water over
the affected spots, making sure it covers everything nicely.
Give
that soil a thorough rinse and let it drain and dry out. The rinsing
will help get rid of any leftover residue, while drying it out helps
with the smell. Just give it some time to air dry before moving on.
If the smell is still lingering, you might want to think about
repotting your plant or using cat deterrents you can find at the store.
Sometimes pee goes deep into the soil, so repotting can refresh things.
And those deterrents can keep those pesky cats away from that spot.
Another trick is to mix vinegar or hydrogen peroxide with water. Spray
this solution onto the stinky area and let it sit for a bit, then rinse
it off. Both vinegar and hydrogen peroxide work wonders when it comes to
neutralizing odors.
And hey, don't forget to clean up your tools properly after you're done.
We don't want any cross-contamination.
By following these steps, you'll say goodbye to that cat urine smell and make your plants happy again.
Main points I'll expand upon further down this article:
Alkaline substances like baking soda can neutralize and eliminate cat urine odor.
Baking soda can be mixed with water as a solution or spray.
Sprinkling baking soda on affected areas and brushing it away is effective.
Vinegar and hydrogen peroxide can be combined with baking soda for added odor reduction.
Activated charcoal, enzymes, citrus peels, coffee grounds, and essential oils can also help neutralize odors.
Cat urine increases soil acidity and urea content, harming plants and nutrient absorption.
Excessive urine can cause salt build-up, making soil too alkaline for some plants.
High nitrogen levels in cat urine lead to imbalances in soil nutrients.
Prevention is key in avoiding soil contamination from repeated urination.
Adding organic matter and planting deodorizing plants can help balance nutrients and absorb odors.

Succession of biochar addition for soil amendment and contaminants remediation during co-composting: A state of art review
2023
Abstract
This
paper aimed to highlight the succession of biochar addition for soil
amendment and contaminants remediation during composting process.
Biochar incorporated into the compost mixture promotes composting
performance and enhances contaminants reduction. Co-composting with
biochar for soil biota has been demonstrated via modified soil
biological community abundance and diversity. On the other hand, adverse
alterations to soil properties were noted, which had a negative impact
on the communication of microbe-to-plant interactions within the
rhizosphere. As a result, these changes influenced the competition
between soilborne pathogens and beneficial soil microorganisms.
Co-composting with biochar promoted the heavy metals (HMs) remediation
efficiency in contaminated soils by around 66–95%. Notably, applying
biochar during composting could improve nutrient retention and mitigate
leaching. The adsorption of nutrients such as nitrogen and phosphorus
compounds by biochar can be applied to manage environmental
contamination and presents an excellent opportunity to enhance soil
quality. Additionally, the various specific functional groups and large
specific surface areas of biochar allow for excellent adsorption of
persistent pollutants (e.g., pesticides, polychlorinated biphenyls
(PCBs)) and emerging organic pollutants, such as microplastic, phthalate
acid esters (PAEs) during co-composting. Finally, future perspectives,
research gaps, and recommendations for further studies are highlighted,
and potential opportunities are discussed.

How Hemp Can Heal Our Soil & Why It Matters To Consumers
February 24, 2024
Not
only can you use hemp to make dozens of sustainable products, from
clothing, skateboards to medicine, but it can also help heal the earth.
As
the human population grows, so do our need for more land to grow the
crops that keep us fed. But our dependence on fossil fuels and dirty
industrial processes have left a lot of land too toxic to sustain life.
That’s where the rapidly growing field of “bioremediation” can be vital.
Bioremediation essentially means using living things to heal the soil,
allowing us to clean and reclaim some of these polluted lands. While
bacteria and other microorganisms can be used, phytoremediation, from
the Greek word for plant, relies on crops like hemp.
Below, we’ll
take a look at the reasons why hemp is such a promising plant for
bioremediation. At the same time, we’ll also touch on the risks posed by
heavy metals and toxins, which can inadvertently end up in hemp-based
consumer products.
Hemp Soil Remediation VS The Chernobyl Nuclear Disaster
One
of the most dramatic demonstrations of industrial hemp‘s potential was
in Chernobyl, in the aftermath of the historic 1986 nuclear disaster
which spewed radioactive waste across Eastern Europe. Over 100,000
square kilometers of Russia, Ukraine, and Belarus were inundated with
radiation, rendering much of them unusable.
In the late 90s, a
company called Phytotech began experimenting with industrial hemp in
some polluted Ukrainian regions. The results were extremely promising.
“Phytoremediation
can be used to remove radioactive elements from soil and water at
former weapons producing facilities,” explained Elaine Charkowski for
Central Oregon Green Pages in winter of 1998. “It can also be used to
clean up metals, pesticides, solvents, explosives, crude oil,
polyaromatic hydrocarbons, and toxins leaching from landfills.”
“Hemp
is proving to be one of the best phyto-remediative plants we have been
able to find,” Slavik Dushenkov, a research scientist with Phytotech,
told Charkowski.
Beyond Radiation: From Cadmium to Oil Spills
In
a paper published in September 2012 in Applied Biochemistry and
Biotechnology, a team of five researchers in China reported on their
successful experiments with hemp to absorb cadmium from the soil. Left
untreated, cadmium in soil can enter the food chain, and consumption can
cause severe joint and spinal pain. Too much exposure is known to even
affect the kidneys and link to cancer.
The scientists
experimented with 18 different varieties of hemp that are native to
China. They identified 7 varieties which exhibited the highest
concentrations of Cadmium (Cd) when grown in polluted soil.

Interaction

Bioremediation-2007.
May 2007
Abstract
The interaction at a root-hair level between Medicago sativa (alfalfa) and Azotobacter through the removal of kerosene hydrocarbons process was studied. The method of Farreus was used to grow Medicago sativa (alfalfa) plants in nitrogen-free Jensen’s medium added with kerosene (1% v/v), and in the presence of Azotobacter nigricans. Under this condition, the removal of kerosene hydrocarbons was 63.1 %, but plants growth was notably shorter than the controls grown without kerosene. Nevertheless, in both systems, a high population of Azotobacter was located in the tips of the roots hair. In the kerosene feed system, the hydrocarbons were observed as oil microscopic droplets adhered to the surface of the whole radical system; that is, in both the hair of the roots and in the principal root tissue. Notably, the major number of Azotobacter cells was concentrated in the droplets located on the surface of the roots hair. These results point out a symbiotic association between Azotobacter and alfalfa at the root-hair level that should be involved in the biochemical process for effective removal of the hydrocarbons.

Microalgal Bioremediation: A Clean and Sustainable Approach for Controlling Environmental Pollution
17 May 2022
Abstract
Environmental
pollution is a major global threat today, with widespread consequences.
Industrial effluents, flue gases, automobile emissions, solid waste,
agricultural runoff, amongst others, have loaded air, water, and soil
with a plethora of undesirable substances harmful for humans and their
surroundings. Common pollutants, such as exhaust gases, heavy metals,
pesticides, pharmaceuticals, and many emerging organic and inorganic
chemicals, are causing multitude of chronic illnesses. With growing
population and rapid industrialization, it is becoming increasingly
important to develop efficient, cheap, sustainable, and scalable
processes to mitigate these life-threatening pollutants.
Conventional
physiochemical methods used for the treatment of industrial, municipal,
and agricultural wastewaters and emissions are effective, but they
suffer serious drawbacks, such as sludge generation, membrane fouling,
and high energy and reagent requirements. This has attracted the use of
biological resources in development of sustainable and eco-friendly
remediation processes. Microalgae particularly have emerged as a
potential microorganism in bioremediation owing to their ability to
adsorb, accumulate, and degrade many common pollutants using different
mechanisms. Concomitant sequestration of carbon dioxide, generation of
oxygen, and accumulation of lipids and carbohydrates with growth are
however the real advantages of using microalgae in bioremediation.
Moreover, simple and cheap nutritional and cultivation requirements of
microalgae make it most suitable bioresource for mitigating pollution.
The development of microalgae-based remediation processes is therefore
an ambitious goal in environmental biotechnology. This chapter reviews
important concepts, developments, challenges, and future prospects of
microalgal bioremediation.

Horizontal ‘gene drives’ harness indigenous bacteria for bioremediation
15 September 2020
Engineering bacteria to clean-up oil spills is rapidly advancing but
faces regulatory hurdles and environmental concerns. Here, we develop a
new technology to harness indigenous soil microbial communities for
bioremediation by flooding local populations with catabolic genes for
petroleum hydrocarbon degradation. Overexpressing three enzymes (almA,
xylE, p450cam) in Escherichia coli led to degradation of 60–99%
of target hydrocarbon substrates. Mating experiments, fluorescence
microscopy and TEM revealed indigenous bacteria could obtain these
vectors from E. coli through several mechanisms of horizontal
gene transfer (HGT), including conjugation and cytoplasmic exchange
through nanotubes. Inoculating petroleum-polluted sediments with E. coli carrying the vector pSF-OXB15-p450camfusion showed that the E. coli
cells died after five days but a variety of bacteria received and
carried the vector for over 60 days after inoculation. Within 60 days,
the total petroleum hydrocarbon content of the polluted soil was reduced
by 46%. Pilot experiments show that vectors only persist in indigenous
populations when under selection pressure, disappearing when this carbon
source is removed. This approach to remediation could prime indigenous
bacteria for degrading pollutants while providing minimal ecosystem
disturbance.

Pocket K No. 25: Biotech Plants for Bioremediation
Conventional Remediation Strategies
Conventional
remediation for polluted sites typically involves the physical removal
of contaminants, and their disposal in a designated site. Physical
remediation strategies therefore do not eliminate the problem, they
merely shift it. In addition, physical remediation strategies are also
very expensive, disruptive to the environment, may temporarily increase
exposure to chemicals, and often leave residual contamination.
Cadmium, Zinc, Lead, and Selenium
Toxic
metals affect crop yields, soil biomass, and fertility, and accumulate
in the food chain. Metal-tolerant species protect themselves from the
toxicity of metal ions by binding metals ions with specific proteins
that render them in a safer form. Three classes of proteins are
important for metal detoxification in plants: metallothioneins,
phytochelatins, and glutathione. The genes coding for these have been
successfully used to improve phytoremediators through genetic
engineering.
For example, shrub tobacco (Nicotiana glauca)
transformed with the phytochelatin TaPCS1 shows very high levels of
accumulation of zinc, lead, cadmium, nickel, and boron, and produces
high biomass (3). In Arabidopsis, Indian mustard, and tobacco plants,
improved metal tolerance was achieved through the over-expression of
enzymes that induce the formation of phytochelatins (4, 5, and 6).
Plants
naturally tolerant to heavy metals have also been used as a source of
genes for phytoremediation. Transgenic Arabidopsis plants expressing a
selenocysteine methyltransferase (SMTA) gene from the selenium
hyperaccumulator Astralagus bisulcatus contain eight times more selenium
in their biomass when grown on selenite compared to non-transgenic
controls. Comparison of gene expression profiles between Arabidopsis
thaliana and the closely related species A. hallerri, which is tolerant
to cadmium and hyperaccumulates zinc, is also helping identify major
genes required for metal tolerance.
Explosives
Millions of
tons of explosives have been released into the environment, with the
resulting pollution of vast expanses of land and water resources. RDX
(Research Department Explosive) was the primary explosive used during
World War II, and newer derivatives are extensively used to date.
Explosives, and their degradation products, are extremely toxic and
corrosive.
Tobacco plants engineered with the bacterial gene for a
NADPH-dependent nitroreductase tolerate and degrade high levels of TNT
(9), and Arabidopsis plants carrying the xplA gene from Rhodococcus
bacteria are highly resistant to of RDX.
Landmines
Landmines
affect millions of people, both combatants and civilians, in over 80
countries. Sixty to 70 million active landmines exist throughout the
world, and these claim the lives and limbs of 50 people every day, and
threaten the livelihood of many more by denying them access to
humanitarian aid, agricultural land, and water resources. Efforts are
underway to develop transgenic plants that can be used to warn civilians
of the presence of landmines in a field. Arabidopsis whose roots change
color when they come into contact with degradation products of
landmines have been developed. Scientists are now working to allow the
plant to transmit the signal to their leaves, to effect human-readable
changes for a practical explosives detection system.
Mercury
Mercury
is a highly toxic element found both naturally and as an introduced
contaminant in the environment, and is a very serious global
environmental problem. Organic mercury (organomercurials), the most
toxic form to living organisms, is produced when bacteria in the water
and soil convert elemental mercury into methylmercury. Methylmercury is
easily absorbed and accumulates at high levels in the food chain.
Mercury poisoning affects the immune system, damages the nervous system,
and is harmful to developing fetuses.
Detoxification of
organomercurials has been achieved in transgenic plants by transforming
Arabidopsis, tobacco, poplar trees, Indian mustard, and eastern cotton
wood with two bacterial genes, merA and merB. (5, 6, 7). The combined
actions of merA and merB transform methylmercury to the volatile
elemental form, which is 100 times less toxic, and is released by the
plant to the atmosphere at non-toxic concentrations through
transpiration.
Arsenic
Arsenic occurs naturally in
rocks and soil, and is released into underground water. Consumption of
contaminated drinking water leads to skin disorders, gangrene, and
cancer of the kidneys and bladder. In addition, high levels of arsenic
in agricultural land degrade soils, reduce crop yields, and introduce
the pollutant to the food chain (8). Arsenic contamination threatens up
to 40 million people in Bangladesh alone, a problem described by the
World Health Organization (WHO) as “the largest poisoning of a
population in history”.
Scientists have engineered Arabidopsis
plants with arsenic tolerance by introducing two bacterial genes: arsC
and y-ECS. arsC converts arsenate, the arsenic form absorbed by plants,
to arsenite. Double transgenics are not only highly tolerant of arsenic,
they also have improved cadmium tolerance, and a six-fold increase in
the level of biomass compared to wild-type controls.

Enhanced
Fenton Reaction for Xenobiotic Compounds and Lignin Degradation Fueled
by Quinone Redox Cycling by Lytic Polysaccharide Monooxygenases
2021
Abstract
The
Fenton reaction is considered to be of great significance in the
initial attack of lignocellulose in wood-decaying fungi. Quinone redox
cycling is the main way to induce the Fenton reaction in fungi. We show
that lytic polysaccharide monooxygenases (LPMOs), through LPMO-catalyzed
oxidation of hydroquinone, can efficiently cooperate with glucose
dehydrogenase (GDH) to achieve quinone redox cycling. The LPMO/GDH
system can enhance Fe3+-reducing activity, H2O2 production, and hydroxyl
radical generation, resulting in a fueled Fenton reaction. The
system-generated hydroxyl radicals exhibited a strong capacity to
decolorize different synthetic dyes and degrade lignin. Our results
reveal a potentially critical connection between LPMOs and the Fenton
reaction, suggesting that LPMOs could be involved in xenobiotic compound
and lignin degradation in fungi. This new role of LPMOs may be
exploited for application in biorefineries.

Energy Conservation and Hydrogenase Function in Methanogenic Archaea, in Particular the Genus Methanosarcina
2019 Sep 18
Summary
The biological production of methane is vital to the global carbon cycle and accounts for ca. 74% of total methane emissions. The organisms that facilitate this process, methanogenic archaea, belong to a large and phylogenetically diverse group that thrives in a wide range of anaerobic environments. Two main subgroups exist within methanogenic archaea: those with and those without cytochromes. Although a variety of metabolisms exist within this group, the reduction of growth substrates to methane using electrons from molecular hydrogen is, in a phylogenetic sense, the most widespread methanogenic pathway. Methanogens without cytochromes typically generate methane by the reduction of CO2 with electrons derived from H2, formate, or secondary alcohols, generating a transmembrane ion gradient for ATP production via an Na+-translocating methyltransferase (Mtr). These organisms also conserve energy with a novel flavin-based electron bifurcation mechanism, wherein the endergonic reduction of ferredoxin is facilitated by the exergonic reduction of a disulfide terminal electron acceptor coupled to either H2 or formate oxidation. Methanogens that utilize cytochromes have a broader substrate range, and can convert acetate and methylated compounds to methane, in addition to the ability to reduce CO2. Cytochrome-containing methanogens are able to supplement the ion motive force generated by Mtr with an H+-translocating electron transport system. In both groups, enzymes known as hydrogenases, which reversibly interconvert protons and electrons to molecular hydrogen, play a central role in the methanogenic process. This review discusses recent insight into methanogen metabolism and energy conservation mechanisms with a particular focus on the genus Methanosarcina.

Methanogenesis
Methanogenesis
or biomethanation is the formation of methane coupled to energy
conservation by microbes known as methanogens. Organisms capable of
producing methane for energy conservation have been identified only from
the domain Archaea, a group phylogenetically distinct from both
eukaryotes and bacteria, although many live in close association with
anaerobic bacteria. The production of methane is an important and
widespread form of microbial metabolism. In anoxic environments, it is
the final step in the decomposition of biomass. Methanogenesis is
responsible for significant amounts of natural gas accumulations, the
remainder being thermogenic.

The origin and evolution of methanogenesis and Archaea are intertwined
31 January 2023
Abstract
Methanogenesis has been widely accepted as an ancient metabolism, but the precise evolutionary trajectory remains hotly debated. Disparate theories exist regarding its emergence time, ancestral form, and relationship with homologous metabolisms. Here, we report the phylogenies of anabolism-involved proteins responsible for cofactor biosynthesis, providing new evidence for the antiquity of methanogenesis. Revisiting the phylogenies of key catabolism-involved proteins further suggests that the last Archaea common ancestor (LACA) was capable of versatile H2-, CO2-, and methanol-utilizing methanogenesis. Based on phylogenetic analyses of the methyl/alkyl-S-CoM reductase family, we propose that, in contrast to current paradigms, substrate-specific functions emerged through parallel evolution traced back to a nonspecific ancestor, which likely originated from protein-free reactions as predicted from autocatalytic experiments using cofactor F430. After LACA, inheritance/loss/innovation centered around methanogenic lithoautotrophy coincided with ancient lifestyle divergence, which is clearly reflected by genomically predicted physiologies of extant archaea. Thus, methanogenesis is not only a hallmark metabolism of Archaea, but the key to resolve the enigmatic lifestyle that ancestral archaea took and the transition that led to physiologies prominent today.

Heterologous
Production of an Energy-Conserving Carbon Monoxide Dehydrogenase
Complex in the Hyperthermophile Pyrococcus furiosus
2016 Jan 29
Abstract
Carbon monoxide (CO) is an important intermediate in anaerobic carbon
fixation pathways in acetogenesis and methanogenesis. In addition, some
anaerobes can utilize CO as an energy source. In the hyperthermophilic
archaeon Thermococcus onnurineus, which grows optimally at
80°C, CO oxidation and energy conservation is accomplished by a
respiratory complex encoded by a 16-gene cluster containing a CO
dehydrogenase, a membrane-bound [NiFe]-hydrogenase and a Na+/H+ antiporter module. This complex oxidizes CO, evolves CO2 and H2, and generates a Na+ motive force that is used to conserve energy by a Na+-dependent
ATP synthase. Herein we used a bacterial artificial chromosome to
insert the 13.2 kb gene cluster encoding the CO-oxidizing respiratory
complex of T. onnurineus into the genome of the heterotrophic archaeon, Pyrococcus furiosus, which grows optimally at 100°C. P. furiosus is normally unable to utilize CO, however, the recombinant strain readily oxidized CO and generated H2 at 80°C. Moreover, CO also served as an energy source and allowed the P. furiosus strain to grow with a limiting concentration of sugar or with peptides as the carbon source. Moreover, CO oxidation by P. furiosus
was also coupled to the re-utilization, presumably for biosynthesis, of
acetate generated by fermentation. The functional transfer of CO
utilization between Thermococcus and Pyrococcus
species demonstrated herein is representative of the horizontal gene
transfer of an environmentally relevant metabolic capability. The
transfer of CO utilizing, hydrogen-producing genetic modules also has
applications for biohydrogen production and a CO-based industrial
platform for various thermophilic organisms.

New
insights into xenobiotic tolerance of Antarctic bacteria:
transcriptomic analysis of Pseudomonas sp. TNT3 during
2,4,6-trinitrotoluene biotransformation
10 February 2024
Abstract
The
xenobiotic 2,4,6-trinitrotoluene (TNT) is a highly persistent
environmental contaminant, whose biotransformation by microorganisms has
attracted renewed attention. In previous research, we reported the
discovery of Pseudomonas sp. TNT3, the first described Antarctic
bacterium with the ability to biotransform TNT. Furthermore, through
genomic analysis, we identified distinctive features in this isolate
associated with the biotransformation of TNT and other xenobiotics.
However, the metabolic pathways and genes active during TNT exposure in
this bacterium remained unexplored. In the present transcriptomic study,
we used RNA-sequencing to investigate gene expression changes in
Pseudomonas sp. TNT3 exposed to 100 mg/L of TNT. The results showed
differential expression of 194 genes (54 upregulated and 140
downregulated), mostly encoding hypothetical proteins. The most highly
upregulated gene (> 1000-fold) encoded an azoreductase enzyme not
previously described. Other significantly upregulated genes were
associated with (nitro)aromatics detoxification, oxidative,
thiol-specific, and nitrosative stress responses, and (nitro)aromatic
xenobiotic tolerance via efflux pumps. Most of the downregulated genes
were involved in the electron transport chain, pyrroloquinoline quinone
(PQQ)-related alcohol oxidation, and motility. These findings highlight a
complex cellular response to TNT exposure, with the azoreductase enzyme
likely playing a crucial role in TNT biotransformation. Our study
provides new insights into the molecular mechanisms of TNT
biotransformation and aids in developing effective TNT bioremediation
strategies. To the best of our knowledge, this report is the first
transcriptomic response analysis of an Antarctic bacterium during TNT
biotransformation.

Diversity and Niche of Archaea in Bioremediation
2018 Sep 3
Abstract
Bioremediation
is the use of microorganisms for the degradation or removal of
contaminants. Most bioremediation research has focused on processes
performed by the domain Bacteria; however, Archaea are known to play
important roles in many situations. In extreme conditions, such as
halophilic or acidophilic environments, Archaea are well suited for
bioremediation. In other conditions, Archaea collaboratively work
alongside Bacteria during biodegradation. In this review, the various
roles that Archaea have in bioremediation is covered, including
halophilic hydrocarbon degradation, acidophilic hydrocarbon degradation,
hydrocarbon degradation in nonextreme environments such as soils and
oceans, metal remediation, acid mine drainage, and dehalogenation.
Research needs are addressed in these areas. Beyond bioremediation,
these processes are important for wastewater treatment (particularly
industrial wastewater treatment) and help in the understanding of the
natural microbial ecology of several Archaea genera.
2. Archaea in the Degradation of Organics in Hypersaline Environments
Perhaps,
the most developed research area that connects Archaea to
bioremediation lies within the degradation of organics in hypersaline
environments. Natural hypersaline environments include salterns, salt
lakes, salt marshes, salt flats (sabkhas), and oil and gas production
wastewaters. The contamination of these environments with crude oil is
common, and about 5% of the chemical, pharmaceutical, and oil industries
have highly saline wastewater effluents in need of treatment. Members
of both Bacteria and Archaea are known to inhabit such environments and
these are often referred to as “halobacteria” and “haloarchaea,”
respectively. Recent reviews have focused on hydrocarbon degradation by
halobacteria and haloarchaea, the biotechnological potential of the
hydrolytic enzyme, the biodiversity of microbial communities in
halophilic environments, the potential of haloarchaea in bioremediation
processes, and the growing rate of research of haloarchaea in
bioremediation. Recently, a new database—called HaloDom—has compiled all
isolated halophilic species into a single online resource. Many
Bacteria can degrade at salinities of up to 15% such as strains of the
genera Ralstonia, Halomonas, Dietzia, and Alcanivorax. Here, an overview
of the haloarchaeal strains isolated on the ability to degrade
hydrocarbons, such as crude oil, is provided.
The haloarchaea
cluster into a single class (the class Halobacteria) within the phylum
Euryarchaeota. They are typically cultured at neutral pH and
temperatures of 30-45°C, and they require high salinities of 1.8–5.0 M
NaCl. Many strains have been traditionally isolated on a standard
nutrient media that contains heterotrophic carbon and energy sources.
Table 1 lists the strains associated with hydrocarbon degradation and
their degradative abilities. Additionally, a phylogenetic tree of many
of these strains (where nearly full-length 16S rRNA gene sequences were
available), as well as other strains and phylogenetic groups discussed
in this manuscript, is shown in Figure 1. The metabolic capabilities of
haloarchaea for hydrocarbon degradation appear vast, and these Archaea
all inhabit a close phylogenetic association.

Haloarchaea: worth exploring for their biotechnological potential
12 September 2017
Abstract
Halophilic
archaea are unique microorganisms adapted to survive under high salt
conditions and biomolecules produced by them may possess unusual
properties. Haloarchaeal metabolites are stable at high salt and
temperature conditions that are useful for industrial applications.
Proteins and enzymes of this group of archaea are functional under salt
concentrations at which bacterial counterparts fail to be active. Such
properties makes haloarchaeal enzymes suitable for salt-based
applications and their use under dehydrating conditions. For example,
bacteriorhodopsin or the purple membrane protein present in halophilic
archaea has the most recognizable applications in photoelectric devices,
artificial retinas, holograms etc. Haloarchaea are also useful for
bioremediation of polluted hypersaline areas. Polyhydroxyalkanoates and
exopolysccharides produced by these microorganisms are biodegradable and
have the potential to replace commercial non-degradable plastics and
polymers. Moreover, halophilic archaea have excellent potential to be
used as drug delivery systems and for nanobiotechnology by virtue of
their gas vesicles and S-layer glycoproteins. Despite of possible
applications of halophilic archaea, laboratory-to-industrial transition
of these potential candidates is yet to be established.

Archaea: An Agro-Ecological Perspective
2021 May 21
Abstract
Microorganisms
inhabiting bulk soil and rhizosphere play an important role in soil
biogeochemical cycles leading to enhanced plant growth and productivity.
In this context, the role of bacteria is well established, however, not
much reports are available about the role archaea plays in this regard.
Literature suggests that archaea also play a greater role in nutrient
cycling of carbon, nitrogen, sulfur, and other minerals, possess various
plant growth promoting attributes, and can impart tolerance to various
abiotic stresses (especially osmotic and oxidative) in areas of high
salinity, low and high temperatures and hydrogen ion concentrations.
Thermoacidophilic archaea have been found to potentially involve in
bioleaching of mineral ores and bioremediation of chemical pollutants
and aromatic compounds. Looking at immense potential of archaea in
promoting plant growth, alleviating abiotic stresses, and remediating
contaminated sites, detailed studies are required to establish their
role in different ecological processes, and their interactions in
rhizosphere with plant and other microflora (bacteria and fungi) in
different ecosystems. In this review, a brief discussion on archaea from
the agro-ecological point of view is presented.

Diversity, metabolism and cultivation of archaea in mangrove ecosystems
02 December 2020
Abstract
Mangroves
comprise a globally significant intertidal ecosystem that contains a
high diversity of microorganisms, including fungi, bacteria and archaea.
Archaea is a major domain of life that plays important roles in
biogeochemical cycles in these ecosystems. In this review, the potential
roles of archaea in mangroves are briefly highlighted. Then, the
diversity and metabolism of archaeal community of mangrove ecosystems
across the world are summarized and Bathyarchaeota, Euryarchaeota,
Thaumarchaeota, Woesearchaeota, and Lokiarchaeota are confirmed as the
most abundant and ubiquitous archaeal groups. The metabolic potential of
these archaeal groups indicates their important ecological function in
carbon, nitrogen and sulfur cycling. Finally, some cultivation
strategies that could be applied to uncultivated archaeal lineages from
mangrove wetlands are suggested, including refinements to traditional
cultivation methods based on genomic and transcriptomic information, and
numerous innovative cultivation techniques such as single-cell
isolation and high-throughput culturing (HTC). These cultivation
strategies provide more opportunities to obtain previously uncultured
archaea.

Distribution and genomic variation of ammonia-oxidizing archaea in abyssal and hadal surface sediments
22 December 2023
Abstract
Ammonia-oxidizing
archaea of the phylum Thaumarchaeota play a central role in the
biogeochemical cycling of nitrogen in benthic sediments, at the
interface between pelagic and subsurface ecosystems. However, our
understanding of their niche separation and of the processes controlling
their population structure in hadal and abyssal surface sediments is
still limited. Here, we reconstructed 47 AOA metagenome-assembled
genomes (MAGs) from surface sediments of the Atacama and Kermadec trench
systems. They formed deep-sea-specific groups within the family
Nitrosopumilaceae and were assigned to six amoA gene-based clades. MAGs
from different clades had distinct distribution patterns along
oxygen-ammonium counter gradients in surface sediments. At the species
level, MAGs thus seemed to form different ecotypes and follow
deterministic niche-based distributions. In contrast, intraspecific
population structure, defined by patterns of Single Nucleotide Variants
(SNV), seemed to reflect more complex contributions of both
deterministic and stochastic processes. Firstly, the bathymetric range
had a strong effect on population structure, with distinct populations
in abyssal plains and hadal trenches. Then, hadal populations were
clearly separated by trench system, suggesting a strong
isolation-by-topography effect, whereas abyssal populations were rather
controlled by sediment depth or geographic distances, depending on the
clade considered. Interestingly, genetic variability between samples was
lowest in sediment layers where the mean MAG coverage was highest,
highlighting the importance of selective pressure linked with each AOA
clade’s ecological niche. Overall, our results show that deep-sea AOA
genome distributions seem to follow both deterministic and stochastic
processes, depending on the genomic variability scale considered.

Extremozymes: A Potential Source for Industrial Applications
2017
Abstract
Extremophilic
microorganisms have established a diversity of molecular strategies in
order to survive in extreme conditions. Biocatalysts isolated by these
organisms are termed extremozymes, and possess extraordinary properties
of salt allowance, thermostability, and cold adaptivity. Extremozymes
are very resistant to extreme conditions owing to their great solidity,
and they pose new opportunities for biocatalysis and biotransformations,
as well as for the development of the economy and new line of research,
through their application. Thermophilic proteins, piezophilic proteins,
acidophilic proteins, and halophilic proteins have been studied during
the last few years. Amylases, proteases, lipases, pullulanases,
cellulases, chitinases, xylanases, pectinases, isomerases, esterases,
and dehydrogenases have great potential application for biotechnology,
such as in agricultural, chemical, biomedical, and biotechnological
processes. The study of extremozymes and their main applications have
emerged during recent years.

Radiation-resistant extremophiles and their potential in biotechnology and therapeutics
Abstract
Extremophiles
are organisms able to thrive in extreme environmental conditions.
Microorganisms with the ability to survive high doses of radiation are
known as radioresistant or radiation-resistant extremophiles. Excessive
or intense exposure to radiation (i.e., gamma rays, X-rays, and
particularly UV radiation) can induce a variety of mutagenic and
cytotoxic DNA lesions, which can lead to different forms of cancer.
However, some populations of microorganisms thrive under different types
of radiation due to defensive mechanisms provided by primary and
secondary metabolic products, i.e., extremolytes and extremozymes.
Extremolytes (including scytonemin, mycosporine-like amino acids,
shinorine, porphyra-334, palythine, biopterin, and phlorotannin, among
others) are able to absorb a wide spectrum of radiation while protecting
the organism's DNA from being damaged. The possible commercial
applications of extremolytes include anticancer drugs, antioxidants,
cell-cycle-blocking agents, and sunscreens, among others. This article
aims to review the strategies by which microorganisms thrive in extreme
radiation environments and discuss their potential uses in biotechnology
and the therapeutic industry. The major challenges that lie ahead are
also discussed.

Archaea: Microbial Candidates in Next-generation Probiotics Development
2018
Abstract
Pharmabiotics
and probiotics in current use or under development belong to 2 of 3
domains of life, Eukarya (eg, yeasts) and Bacteria (eg, lactobacilli).
Archaea constitute a third domain of life, and are currently not used as
probiotics, despite several interesting features. This includes the
absence of known pathogens in humans, animals, or plants and the
existence of some archaea closely associated to humans in various
microbiomes. We promote the concept that some specific archaea that
naturally thrive in the human gut are potential next-generation
probiotics that can be rationally selected on the basis of their
metabolic phenotype not being encountered in other human gut microbes,
neither Bacteria nor Eukarya. The example of the possible bioremediation
of the proatherogenic compound trimethylamine into methane by archaeal
microbes is described.

Observed fingerprint of a weakening Atlantic Ocean overturning circulation
11 April 2018
Abstract
The Atlantic meridional overturning circulation (AMOC)—a system of ocean
currents in the North Atlantic—has a major impact on climate, yet its
evolution during the industrial era is poorly known owing to a lack of
direct current measurements. Here we provide evidence for a weakening of
the AMOC by about 3 ± 1 sverdrups (around 15 per cent) since the
mid-twentieth century. This weakening is revealed by a characteristic
spatial and seasonal sea-surface temperature ‘fingerprint’—consisting of
a pattern of cooling in the subpolar Atlantic Ocean and warming in the
Gulf Stream region—and is calibrated through an ensemble of model
simulations from the CMIP5 project. We find this fingerprint both in a
high-resolution climate model in response to increasing atmospheric
carbon dioxide concentrations, and in the temperature trends observed
since the late nineteenth century. The pattern can be explained by a
slowdown in the AMOC and reduced northward heat transport, as well as an
associated northward shift of the Gulf Stream. Comparisons with recent
direct measurements from the RAPID project and several other studies
provide a consistent depiction of record-low AMOC values in recent
years.

A conceptual view on inertial internal waves in relation to the subinertial flow on the central west Florida shelf
29 October 2018
Abstract
The
study reported here focuses on inertial internal wave currents on the
west Florida midshelf in 50 m depth. In situ observations showed that
the seasonal shifts in stratification change both the frequency range of
inertial internal waves and their modulation time scales. According to
the analysis, the subinertial flow evolution time scales also undergo
compatible seasonal variations, and the inertial internal wave currents
appear to be temporally and spatially related to the subinertial flow.
Specifically, the subinertial flow evolving on
frontal-/quasi-geostrophic time scales appears to be accompanied by the
near-inertial oscillations/inertia-gravity waves in corresponding
small/finite Burger number regimes, respectively. The quasi-geostrophic
subinertial currents on the west Florida shelf are probably associated
with the synoptic wind-forced flow, whereas the frontal-geostrophic
currents are related to the evolution of density fronts. Further details
of this conceptual view should, however, be elucidated in the future.

Weakening Atlantic overturning circulation causes South Atlantic salinity pile-up
14 September 2020
Abstract
The
Atlantic Meridional Overturning Circulation (AMOC) is an active
component of the Earth’s climate system1 and its response to global
warming is of critical importance to society. Climate models have shown
an AMOC slowdown under anthropogenic warming since the industrial
revolution, but this slowdown has been difficult to detect in the
short observational record because of substantial
interdecadal climate variability. This has led to the indirect detection
of the slowdown from longer-term fingerprints such as the
subpolar North Atlantic ‘warming hole’. However, these fingerprints,
which exhibit some uncertainties, are all local indicators of AMOC
slowdown around the subpolar North Atlantic. Here we show observational
and modelling evidence of a remote indicator of AMOC slowdown outside
the North Atlantic. Under global warming, the weakening AMOC reduces the
salinity divergence and then leads to a ‘salinity pile-up’ remotely in
the South Atlantic. This evidence is consistent with the AMOC slowdown
under anthropogenic warming and, furthermore, suggests that this
weakening has likely occurred all the way into the South Atlantic.

A stable Atlantic Meridional Overturning Circulation in a changing North Atlantic Ocean since the 1990s
27 Nov 2020
Abstract
The
Atlantic Meridional Overturning Circulation (AMOC) is crucially
important to global climate. Model simulations suggest that the AMOC may
have been weakening over decades. However, existing array-based AMOC
observations are not long enough to capture multidecadal changes. Here,
we use repeated hydrographic sections in the subtropical and subpolar
North Atlantic, combined with an inverse model constrained using
satellite altimetry, to jointly analyze AMOC and hydrographic changes
over the past three decades. We show that the AMOC state in the past
decade is not distinctly different from that in the 1990s in the North
Atlantic, with a remarkably stable partition of the subpolar overturning
occurring prominently in the eastern basins rather than in the Labrador
Sea. In contrast, profound hydrographic and oxygen changes,
particularly in the subpolar North Atlantic, are observed over the same
period, suggesting a much higher decoupling between the AMOC and ocean
interior property fields than previously thought.

Likely weakening of the Florida Current during the past century revealed by sea-level observations
07 August 2020
The Florida Current marks the beginning of the Gulf Stream at Florida
Straits, and plays an important role in climate. Nearly continuous
measurements of Florida Current transport are available at 27°N since
1982. These data are too short for assessing possible multidecadal or
centennial trends. Here I reconstruct Florida Current transport during
1909–2018 using probabilistic methods and principles of ocean physics
applied to the available transport data and longer coastal sea-level
records. Florida Current transport likely declined steadily during the
past century. Transport since 1982 has likely been weaker on average
than during 1909–1981. The weakest decadal-mean transport in the last
110 y likely took place in the past two decades. Results corroborate
hypotheses that the deep branch of the overturning circulation declined
over the recent past, and support relationships observed in climate
models between the overturning and surface western boundary current
transports at multidecadal and longer timescales.

The evolution of the North Atlantic Meridional Overturning Circulation since 1980
01 March 2022
Abstract
The
Atlantic Meridional Overturning Circulation (AMOC) is a key component
of the climate through its transport of heat in the North Atlantic
Ocean. Decadal changes in the AMOC, whether through internal variability
or anthropogenically forced weakening, therefore have wide-ranging
impacts. In this Review, we synthesize the understanding of contemporary
decadal variability in the AMOC, bringing together evidence from
observations, ocean reanalyses, forced models and AMOC proxies. Since
1980, there is evidence for periods of strengthening and weakening,
although the magnitudes of change (5–25%) are uncertain. In the subpolar
North Atlantic, the AMOC strengthened until the mid-1990s and then
weakened until the early 2010s, with some evidence of a strengthening
thereafter; these changes are probably linked to buoyancy forcing
related to the North Atlantic Oscillation. In the subtropics, there is
some evidence of the AMOC strengthening from 2001 to 2005 and strong
evidence of a weakening from 2005 to 2014. Such large interannual and
decadal variability complicates the detection of ongoing long-term
trends, but does not preclude a weakening associated with anthropogenic
warming. Research priorities include developing robust and sustainable
solutions for the long-term monitoring of the AMOC,
observation–modelling collaborations to improve the representation of
processes in the North Atlantic and better ways to distinguish
anthropogenic weakening from internal variability.

Scientists identify asymmetry in the pressure anomalies of the mid–high latitudes of the Southern Hemisphere
March 31, 2022
In
the Southern Hemisphere, a zonally oriented high pressure belt extends
around the globe in the subtropics and middle latitudes, while lower
pressure covers the high latitudes. The pressure in these two regions
fluctuates. The Southern Annular Mode (SAM) reflects such fluctuation,
which shows a "seesaw" phenomenon of pressure variation in the mid–high
latitudes of the Southern Hemisphere. It is called an "annular mode"
because of the belt-shaped pressure anomaly in the middle latitudes, and
its structure is zonally symmetric. However, some studies have shown
some SAM events to be characterized by zonal asymmetries, the structure
of which has been revealed in a recent study published in Atmospheric
and Oceanic Science Letters.

Trends and variability in the Southern Annular Mode over the Common Era
22 April 2023
Abstract
The Southern Annular Mode (SAM) is the leading mode of atmospheric
variability in the extratropical Southern Hemisphere and has wide
ranging effects on ecosystems and societies. Despite the SAM’s
importance, paleoclimate reconstructions disagree on its variability and
trends over the Common Era, which may be linked to variability in SAM
teleconnections and the influence of specific proxies. Here, we use data
assimilation with a multi-model prior to reconstruct the SAM over the
last 2000 years using temperature and drought-sensitive climate proxies.
Our method does not assume a stationary relationship between the SAM
and the proxy records and allows us to identify critical paleoclimate
records and quantify reconstruction uncertainty through time. We find no
evidence for a forced response in SAM variability prior to the 20th
century. We do find the modern positive trend falls outside the 2σ
range of the prior 2000 years at multidecadal time scales, supporting
the inference that the SAM’s positive trend over the last several
decades is a response to anthropogenic climate change.

Global changes in oceanic mesoscale currents over the satellite altimetry record
22 April 2021
Abstract
Oceanic mesoscale eddies play a profound role in mixing tracers such as
heat, carbon and nutrients, thereby regulating regional and global
climate. Yet, it remains unclear how the eddy field has varied over the
past few decades. Furthermore, climate model predictions generally do
not resolve mesoscale eddies, which could limit their accuracy in
simulating future climate change. Here we show a global statistically
significant increase of ocean eddy activity using two independent
observational datasets of surface mesoscale eddy variability (one
estimates surface currents, and the other is derived from sea surface
temperature). Maps of mesoscale variability trends show heterogeneous
patterns, with eddy-rich regions showing a significant increase in
mesoscale variability of 2–5% per decade, while the tropical oceans show
a decrease in mesoscale variability. This readjustment of the surface
mesoscale ocean circulation has important implications for the exchange
of heat and carbon between the ocean and atmosphere.

Weaker Gulf Stream in the Florida Straits during the Last Glacial Maximum
09 December 1999
Abstract
As
it passes through the Florida Straits, the Gulf Stream consists of two
main components: the western boundary flow of the wind-driven
subtropical gyre and the northward-flowing surface and intermediate
waters which are part of the ‘global conveyor belt’, compensating for
the deep water that is exported from the North Atlantic Ocean1. The mean
flow through the Straits is largely in geostrophic balance and is thus
reflected in the contrast in seawater density across the Straits. Here
we use oxygen-isotope ratios of benthic foraminifera which lived along
the ocean margins on the boundaries of the Florida Current during the
Last Glacial Maximum to determine the density structure in the water and
thereby reconstruct transport through the Straits using the geostrophic
method—a technique which has been used successfully for estimating
present-day flow. Our data suggest that during the Last Glacial
Maximum, the density contrast across the Florida Straits was reduced,
with the geostrophic flow, referenced to the bottom of the channel, at
only about two-thirds of the modern value. If the wind-driven western
boundary flow was not lower during the Last Glacial Maximum than today,
these results indicate a significantly weaker conveyor-belt component of
the Gulf Stream compared to present-day values. Whereas previous
studies based on tracers suggested that deep waters of North Atlantic
origin were not widespread during glacial times, indicating either a
relatively weak or a shallow overturning cell, our results provide
evidence that the overturning cell was indeed weaker during glacial
times.

Abrupt
Changes in Atmospheric Circulation During the Medieval Climate Anomaly
and Little Ice Age Recorded by Sr-Nd Isotopes in the Siple Dome Ice
Core, Antarctica
21 March 2023
Abstract
The Southern Hemisphere westerly winds (SWW) play a critical role in
global climate, yet their behavior on decadal to centennial timescales,
and the mechanisms driving these changes during the preindustrial era,
remain poorly understood. We present a decadally resolved record of dust
compositions using strontium and neodymium isotope ratios in mineral
dust from the Siple Dome ice core, Antarctica, to explore the potential
that abrupt changes in SWW behavior occurred over the past millennium.
The record spans portions of the Medieval Climate Anomaly (MCA) and the
Little Ice Age (LIA) intervals as defined in the Northern Hemisphere. We
find evidence of an abrupt strengthening of atmospheric circulation
during the MCA at ∼1125 CE (825 BP) that persisted for about 60 yr,
indicating increased influence of Patagonia-sourced dust. This occurs
during an extended positive phase of Southern Annular Mode (SAM+)-like
conditions, characterized by high SWW velocities and a southerly shift
of the main wind belt toward ∼60°S, suggesting that rapid changes in SWW
strength could occur under the present SAM+ pattern. A second 20 yr
long shift in dust compositions during the LIA at ∼1748 CE (200 BP) is
coincident with higher dust delivery to Siple Dome, and may indicate
increased dust emissions related to glacier activity in Patagonia. The
new Siple Dome ice core data set demonstrates that Sr-Nd isotopes can be
used to trace shifts in atmospheric circulation on decadal timescales.

Impact
of changes in sea surface temperature due to climate change on
hurricane wind and storm surge hazards across US Atlantic and Gulf coast
regions
09 July 2023
Abstract
Communities in US
coastal regions are threatened by hurricanes more than ever, and the
effect of climate change may further aggravate the risk and
corresponding losses in the future. This paper investigates the
potential impact of changes in sea surface temperature (SST) on
hurricane wind and storm surge hazards for the Atlantic and Gulf coast
regions. An empirical track model that uses SST as an input is used to
account for the effect of temperature variations on hurricane intensity.
The storm surge hazard is modeled using Sea, Lake, and Overland Surges
from Hurricanes (SLOSH). Four projected future climate conditions based
on the Intergovernmental Panel on Climate Change (IPCC) emission
scenarios are adopted to capture the effect of changes in SST on future
hurricane intensity. The impacts of changes in hurricane frequency and
sea-level rise are also considered. The results show that the projected
increase in the average SST will lead to more intense hurricanes by the
end of the twenty-first century. An increase in wind speed for all the
studied sites with varying degrees is observed. The most significant
increase in wind speeds is observed on the northeast Atlantic coast,
with some areas showing an increase of more than 60% for high return
period winds under the most extreme future climate scenario. This is
because a higher increase in SST is observed in such areas, which will
lead to more intense hurricanes in the future. An increasing trend is
also observed for the storm surge for all the study sites in the future.
However, the largest increase in predicted surge heights is mainly seen
in the Gulf Coast locations.

The weakening AMOC under extreme climate change
06 October 2023
Abstract
Changes in the Atlantic Meridional Overturning Circulation (AMOC) in the quadrupled CO2 experiments conducted under the sixth Coupled Model Intercomparison Project (CMIP6) are examined. Increased CO2
triggers extensive Arctic warming, causing widespread melting of sea
ice. The resulting freshwater spreads southward, first from the Labrador
Sea and then the Nordic Seas, and proceeds along the eastern coast of
North America. The freshwater enters the subpolar gyre north of the
separated Gulf Stream, the North Atlantic Current. This decreases the
density gradient across the current and the current weakens in response,
reducing the inflow to the deepwater production regions. The AMOC cell
weakens in tandem, first near the North Atlantic Current and then
spreading to higher and lower latitudes. This contrasts with the common
perception that freshwater caps the convection regions, stifling
deepwater production; rather, it is the inflow to the subpolar gyre that
is suppressed. Changes in surface temperature have a much weaker
effect, and there are no consistent changes in local or remote wind
forcing among the models. Thus an increase in freshwater discharge,
primarily from the Labrador Sea, is the precursor to AMOC weakening in
these simulations.

South Atlantic Anomaly
The
South Atlantic Anomaly (SAA) is an area where Earth's inner Van Allen
radiation belt comes closest to Earth's surface, dipping down to an
altitude of 200 kilometres (120 mi). This leads to an increased flux of
energetic particles in this region and exposes orbiting satellites
(including the ISS) to higher-than-usual levels of ionizing radiation.
The
effect is caused by the non-concentricity of Earth and its magnetic
dipole and has been observed to be increasing in intensity
recently.[quantify] The SAA is the near-Earth region where Earth's
magnetic field is weakest relative to an idealized Earth-centered dipole
field.
Definition
The area of the SAA is confined by the
intensity of Earth's magnetic field at less than 32,000 nanotesla at
sea level,[1] which corresponds to the dipolar magnetic field at
ionospheric altitudes.[2] However, the field itself varies in intensity
as a gradient.

Geomagnetic South Atlantic Anomaly and global sea level rise: A direct connection?
2011
We highlight the existence of an intriguing and to date unreported relationship between the surface area of the South Atlantic Anomaly (SAA) of the geomagnetic field and the current trend in global sea level rise. These two geophysical variables have been growing coherently during the last three centuries, thus strongly suggesting a causal relationship supported by some statistical tests. The monotonic increase of the SAA surface area since 1600 may have been associated with an increased inflow of radiation energy through the inner Van Allen belt with a consequent warming of the Earth's atmosphere and finally global sea level rise. An alternative suggestive and original explanation is also offered, in which pressure changes at the core–mantle boundary cause surface deformations and relative sea level variations. Although we cannot establish a clear connection between SAA dynamics and global warming, the strong correlation between the former and global sea level supports the idea that global warming may be at least partly controlled by deep Earth processes triggering geomagnetic phenomena, such as the South Atlantic Anomaly, on a century time scale.
Highlights
► We compare South Atlantic Anomaly (SAA) surface and sea level in the last 300 years. ► SAA and sea level show a strong correlation supported by statistical tests. ► Increasing the SAA surface may have increased the inflow of radiation energy. ► The radiation energy may have warmed the atmosphere causing the sea level change. ► Alternatively magnetic field and sea level changes may have a common internal cause.

Slowdown of Antarctic Bottom Water export driven by climatic wind and sea-ice changes
12 June 2023
Abstract
Antarctic Bottom Water (AABW) is pivotal for oceanic heat and carbon
sequestrations on multidecadal to millennial timescales. The Weddell Sea
contributes nearly a half of global AABW through Weddell Sea Deep Water
and denser underlying Weddell Sea Bottom Water that form on the
continental shelves via sea-ice production. Here we report an observed
30% reduction of Weddell Sea Bottom Water volume since 1992, with the
largest decrease in the densest classes. This is probably driven by a
multidecadal reduction in dense-water production over southern
continental shelf associated with a >40% decline in the sea-ice
formation rate. The ice production decrease is driven by northerly wind
trend, related to a phase transition of the Interdecadal Pacific
Oscillation since the early 1990s, superposed by Amundsen Sea Low
intrinsic variability. These results reveal key influences on exported
AABW to the Atlantic abyss and their sensitivity to large-scale,
multidecadal climate variability.

Influence of glacial ice sheets on the Atlantic meridional overturning circulation through surface wind change
31 July 2017
Abstract
Coupled
modeling studies have recently shown that the existence of the glacial
ice sheets intensifies the Atlantic meridional overturning circulation
(AMOC). However, most models show a strong AMOC in their simulations of
the Last Glacial Maximum (LGM), which is biased compared to
reconstructions that indicate both a weaker and stronger AMOC during the
LGM. Therefore, a detailed investigation of the mechanism behind this
intensification of the AMOC is important for a better understanding of
the glacial climate and the LGM AMOC. Here, various numerical
simulations are conducted to focus on the effect of wind changes due to
glacial ice sheets on the AMOC and the crucial region where the wind
modifies the AMOC. First, from atmospheric general circulation model
experiments, the effect of glacial ice sheets on the surface wind is
evaluated. Second, from ocean general circulation model experiments, the
influence of the wind stress change on the AMOC is evaluated by
applying wind stress anomalies regionally or at different magnitudes as a
boundary condition. These experiments demonstrate that glacial ice
sheets intensify the AMOC through an increase in the wind stress at the
North Atlantic mid-latitudes, which is induced by the North American ice
sheet. This intensification of the AMOC is caused by the increased
oceanic horizontal and vertical transport of salt, while the change in
sea ice transport has an opposite, though minor, effect. Experiments
further show that the Eurasian ice sheet intensifies the AMOC by
directly affecting the deep-water formation in the Norwegian Sea.

Interbasin and interhemispheric impacts of a collapsed Atlantic Overturning Circulation
06 June 2022
Climate
projections suggest a weakening or collapse of the Atlantic Meridional
Overturning Circulation (AMOC) under global warming, with evidence that a
slowdown is already underway. This could have significant ramifications
for Atlantic Ocean heat transport, Arctic sea ice extent and regional
North Atlantic climate. However, the potential for far-reaching effects,
such as teleconnections to adjacent basins and into the Southern
Hemisphere, remains unclear. Here, using a global climate model we show
that AMOC collapse can accelerate the Pacific trade winds and Walker
circulation by leaving an excess of heat in the tropical South Atlantic.
This tropical warming drives anomalous atmospheric convection,
resulting in enhanced subsidence over the east Pacific and a
strengthened Walker circulation and trade winds. Further teleconnections
include weakening of the Indian and South Atlantic subtropical highs
and deepening of the Amundsen Sea Low. These findings have important
implications for understanding the global climate response to ongoing
greenhouse gas increases.

Dynamics of Southern Hemisphere Atmospheric Circulation Response to Anthropogenic Aerosol Forcing
28 September 2020
Abstract
Anthropogenic
aerosols, concentrated largely in the Northern Hemisphere, not only
affect the local climate but also induce pronounced changes in
atmospheric circulation that extend into the Southern Hemisphere (SH).
In coupled historical single-forcing simulations, aerosol forcing
induces a deceleration of both the subpolar jet (SPJ) and the
subtropical jet (STJ) in SH in austral winter. Atmospheric general
circulation model experiments indicate that the STJ is weakened by an
interhemisphere gradient in the zonal mean sea surface temperature (SST)
and an anomalous cross-equatorial Hadley circulation, while the SPJ
response shares similar feedbacks with the greenhouse gas forcing.
Specifically, atmospheric eddy adjustments are important for the SPJ
change. The atmospheric response unique to anthropogenic aerosol forcing
(e.g., cross-equatorial Hadley cell and the weakened SH STJ) can be
exploited for climate change attribution.
Key Points
The Southern Hemisphere atmospheric circulation change is identified in response to anthropogenic aerosol forcing
The aerosol forcing weakens the subtropical jet and strengthens the
subpolar jet due to the interhemisphere asymmetric SST response
The spatially uniform cooling effect of aerosols induces a subpolar and
subtropical jet change similar to the GHG effect with sign reversed

Southern Hemisphere westerly wind changes during the Last Glacial Maximum: model-data comparison
2012
Abstract
The Southern Hemisphere (SH) westerly winds are thought to be critical to global ocean circulation, productivity, and carbon storage. For example, an equatorward shift in the winds, though its affect on the Southern Ocean circulation, has been suggested as the leading cause for the reduction in atmospheric CO2 during the Last Glacial period. Despite the importance of the winds, it is currently not clear, from observations or model results, how they behave during the Last Glacial. Here, an atmospheric modelling study is performed to help determine likely changes in the SH westerly winds during the Last Glacial Maximum (LGM). Using LGM boundary conditions, the maximum in SH westerlies is strengthened by ∼+1 m s−1 and moved southward by ∼2° at the 850 hPa pressure level. Boundary layer stabilisation effects over equatorward extended LGM sea-ice can lead to a small apparent equatorward shift in the wind band at the surface. Further sensitivity analysis with individual boundary condition changes indicate that changes in sea surface temperatures are the strongest factor behind the wind change. The HadAM3 atmospheric simulations, along with published PMIP2 coupled climate model simulations, are then assessed against the newly synthesised database of moisture observations for the LGM. Although the moisture data is the most commonly cited evidence in support of a large equatorward shift in the SH winds during the LGM, none of the models that produce realistic LGM precipitation changes show such a large equatorward shift. In fact, the model which best simulates the moisture proxy data is the HadAM3 LGM simulation which shows a small poleward wind shift. While we cannot prove here that a large equatorward shift would not be able to reproduce the moisture data as well, we show that the moisture proxies do not provide an observational evidence base for it.

Weird behavior of Earth's magnetic field over South Atlantic dates back 11 million years
July 06, 2022
Strange
behavior in Earth's magnetic field over the South Atlantic region can
be traced back as far as 11 million years ago, and it's unlikely to
cause any impending reversal of Earth's magnetic field, a new study
shows.
The South Atlantic Anomaly is a weak spot in Earth's
magnetic field, which protects the planet from high doses of solar wind
and cosmic radiation. This anomaly exists because the Earth's inner Van
Allen radiation belt comes closest to the planet’s surface, causing an
increased flux of energetic particles. In turn, this anomaly also causes
technical disturbances in satellites and spacecraft orbiting Earth.
Researchers
from the University of Liverpool in England studied igneous, or
volcanic rocks from the island Saint Helena, which lies in the South
Atlantic Anomaly. Records of Earth's magnetic field are preserved in
igneous rocks, offering a detailed view of the planet's magnetic
history.
"Our study provides the first long term analysis of the
magnetic field in this region dating back millions of years," Yael
Engbers, lead author of the study, said in a statement. "It reveals that
the anomaly in the magnetic field in the South Atlantic is not a
one-off, similar anomalies existed eight to 11 million years ago."
Researchers
studied rocks from 34 volcanic eruptions that occurred at Saint Helena
between 8 and 11 million years ago. When volcanic rocks cool down, small
grains of iron-oxide in them get magnetized, preserving the direction
and strength of the Earth’s magnetic field at that time and place.
Earth's
magnetic field lines run from south to north. The geomagnetic records
from the rocks show that the magnetic field at Saint Helena has pointed
in different directions during past eruptions. This suggests that the
magnetic field in this region has been unstable for millions of years.
Earth's
magnetic field changes in strength and direction over time. It is
believed that these fluctuations may eventually trigger a reversal of
the Earth's magnetic field. However, given that the magnetic field at
the region of the South Atlantic Anomaly has been unstable for several
million years, it is not likely associated with any such impending
reversal, according to the statement.
"It also supports earlier
studies that hint towards a link between the South Atlantic Anomaly and
anomalous seismic features in the lowermost mantle and the outer core,"
Engbers said in the statement. "This brings us closer to linking
behavior of the geomagnetic field directly to features of the Earth's
interior."

The South Atlantic Anomaly May Go Back Far Longer Than Anybody Knew
21 July 2020
For
years, scientists have been gripped by the existence of a strange
anomaly weakening Earth's magnetic field. It's located in the midst of
the South Atlantic ocean, extending all the way from South America to
the west coast of southern Africa.
This giant, puzzling expanse
of reduced magnetic intensity – which in recent times looks to be
splitting into two divided entities – means the region offers less
protection against harmful radiation from the Sun for Earth's
satellites.
That's a problem for spacecraft today. But perhaps
the greatest significance of the 'South Atlantic Anomaly' is what it
might mean for tomorrow: specifically, whether the mysterious phenomenon
foreshadows the beginnings of a complete polar reversal of Earth's
magnetic field.
Such giant magnetic flips have occurred many
times in our planet's history, and some scientists have speculated that
the South Atlantic Anomaly could be a kind of precursor to these rare
global transitions.
Not so, according to a new study from
researchers at the University of Liverpool in the UK. The alternative
explanation they have is, in some ways, even stranger: the South
Atlantic Anomaly is not so much a freak irregularity of recent history,
but a recurrent magnetic phenomenon that has affected Earth since as far
back as 11 million years ago.
"Our study provides the first
long-term analysis of the magnetic field in this region dating back
millions of years," says first author and palaeomagnetism researcher
Yael Engbers.
"It reveals that the anomaly in the magnetic field
in the South Atlantic is not a one-off, similar anomalies existed eight
to 11 million years ago."

Fast upper-level jet stream winds get faster under climate change
30 November 2023
Abstract
Earth’s
upper-level jet streams influence the speed and direction of travel of
weather systems and commercial aircraft, and are linked to severe
weather occurrence. Climate change is projected to accelerate the
average upper-level jet stream winds. However, little is known about how
fast (>99th percentile) upper-level jet stream winds will change.
Here we show that fast upper-level jet stream winds get faster under
climate change using daily data from climate model projections across a
hierarchy of physical complexity. Fast winds also increase ~2.5 times
more than the average wind response. We show that the multiplicative
increase underlying the fast-get-faster response follows from the
nonlinear Clausius–Clapeyron relation (moist-get-moister response). The
signal is projected to emerge in both hemispheres by 2050 when
considering scenario uncertainty. The results can be used to explain
projected changes in commercial flight times, record-breaking winds,
clear-air turbulence and a potential increase in severe weather
occurrence under climate change.

Satellite Observations of Imprint of Oceanic Current on Wind Stress by Air-Sea Coupling
18 December 2017
Abstract
Mesoscale eddies are present everywhere in the ocean and partly
determine the mean state of the circulation and ecosystem. The current
feedback on the surface wind stress modulates the air-sea transfer of
momentum by providing a sink of mesoscale eddy energy as an atmospheric
source. Using nine years of satellite measurements of surface stress and
geostrophic currents over the global ocean, we confirm that the
current-induced surface stress curl is linearly related to the current
vorticity. The resulting coupling coefficient between current and
surface stress (sτ [N s m−3]) is heterogeneous and can be roughly expressed as a linear function of the mean surface wind. sτ
expresses the sink of eddy energy induced by the current feedback. This
has important implications for air-sea interaction and implies that
oceanic mean and mesoscale circulations and their effects on
surface-layer ventilation and carbon uptake are better represented in
oceanic models that include this feedback.

Mysterious South Atlantic Anomaly is “Deepening,” Recent Government Report Says

An
anomalous magnetic region in the South Atlantic Ocean is growing,
according to data that appeared in a government report published earlier
this year.
The South Atlantic Anomaly is a location in the
southern Atlantic where the innermost portions of the natural zone of
energetic charged particles encircling Earth, known as the Van Allen
radiation belt, makes its closest approach to the planet. The resulting
outflow of energized particles produces a higher yield of ionizing
radiation detectable by satellites orbiting Earth.

A shift in the ocean circulation has warmed the subpolar North Atlantic Ocean since 2016
26 February 2021
Abstract
The
Subpolar North Atlantic is known for rapid reversals of decadal
temperature trends, with ramifications encompassing the large-scale
meridional overturning and gyre circulations, Arctic heat and mass
balances, or extreme continental weather. Here, we combine datasets
derived from sustained ocean observing systems (satellite and in situ),
idealized observation-based modelling (advection-diffusion of a passive
tracer), and a machine learning technique (ocean profile clustering) to
document and explain the most-recent and ongoing cooling-to-warming
transition of the Subpolar North Atlantic. Following a gradual cooling
of the region that was persisting since 2006, a surface-intensified and
large-scale warming sharply emerged in 2016 following an ocean
circulation shift that enhanced the northeastward penetration of warm
and saline waters from the western subtropics. The long ocean memory of
the Subpolar North Atlantic implies that this advection-driven warming
is likely to persist in the near-future with possible implications for
the Atlantic multidecadal variability and its global impacts.

Ocean warming and accelerating Southern Ocean zonal flow
29 November 2021
Abstract
The
Southern Ocean (>30° S) has taken up a large amount of anthropogenic
heat north of the Subantarctic Front (SAF) of the Antarctic Circumpolar
Current (ACC). Poor sampling before the 1990s and decadal variability
have heretofore masked the ocean’s dynamic response to this warming.
Here we use the lengthening satellite altimetry and Argo float records
to show robust acceleration of zonally averaged Southern Ocean zonal
flow at 48° S–58° S. This acceleration is reproduced in a hierarchy of
climate models, including an ocean-eddy-resolving model. Anthropogenic
ocean warming is the dominant driver, as large (small) heat gain in the
downwelling (upwelling) regime north (south) of the SAF causes zonal
acceleration on the northern flank of the ACC and adjacent subtropics
due to increased baroclinicity; strengthened wind stress is of secondary
importance. In Drake Passage, little warming occurs and the SAF
velocity remains largely unchanged. Continued ocean warming could
further accelerate Southern Ocean zonal flow.

Unusual nighttime impulsive foF2 enhancement below the southern anomaly crest under geomagnetically quiet conditions
2011
Abstract
An
unusual nighttime impulsive electron density enhancement was observed
on 6 March 2010 over a wide region of South America, below the southern
crest of the equatorial anomaly, under low solar activity and quiet
geomagnetic conditions. The phenomenon was observed almost
simultaneously by the F2 layer critical frequency (foF2) recorded at
three ionospheric stations which are widely distributed in space, namely
Cachoeira Paulista (22.4°S, 44.6°W, magnetic latitude 13.4°S), São José
dos Campos (23.2°S, 45.9°W, magnetic latitude 14.1°S), Brazil, and
Tucumán (26.9°S, 65.4°W, magnetic latitude 16.8°S), Argentina. Although
in a more restricted region over Tucumán, the phenomenon was also
observed by the total electron content (TEC) maps computed by using
measurements from 12 GPS receivers. The investigated phenomenon is very
particular because besides being of brief duration, it is characterized
by a pronounced compression of the ionosphere. This compression was
clearly visible both by the virtual height of the base of the F region
(h′F) recorded at the aforementioned ionospheric stations, and by both
the vertical electron density profiles and the slab thickness computed
over Tucumán. Consequently, neither an enhanced fountain effect nor
plasma diffusion from the plasmasphere can be considered as the single
cause of this unusual event. A thorough analysis of isoheight and
isofrequency ionosonde plots suggest that traveling ionospheric
disturbances (TIDs) caused by gravity wave (GW) propagation could have
likely played a significant role in causing the phenomenon.

Effects of Electric Field and Neutral Wind on the Asymmetry of Equatorial Ionization Anomaly
17 April 2018
Abstract
The
zonal electric field and the meridional neutral wind are the principal
drivers that define the geometry and characteristics of the equatorial
ionization anomaly (EIA). Here we present the response of the EIA to the
variability of the zonal electric field based on measurements of the
equatorial electrojet (EEJ) currents and trans-equatorial neutral winds
for the generation and control of the asymmetries of the EIA crests of
total electron content (TEC) in the western side of the South American
continent. The EEJ strengths are determined using a pair of
magnetometers. The 24-hr trans-equatorial neutral wind profile is
measured using the Second-Generation, Optimized, Fabry-Perot Doppler
Imager (SOFDI) located near the geomagnetic equator. The EIA is
evaluated using TEC data measured by Global Positioning System (GPS)
receivers from the Low-Latitude Ionospheric Sensor Network and several
other networks in South America. A physics-based numerical model,
Low-Latitude Ionospheric Sector, and SOFDI data are used to study the
effects of daytime meridional neutral winds on the consequent evolution
of an asymmetry in equatorial TEC anomalies during the afternoon and
onward for the first time. We find that the configuration parameters
such as strength, shape, amplitude, and latitudinal width of the EIAs
are affected by the eastward electric field associated with the EEJ
under undisturbed conditions. The asymmetries of EIA crests are observed
more frequently during solstices and the September equinox than in the
March equinox season. Importantly, this study indicates that the
meridional neutral wind plays a very significant role in the development
of the EIA asymmetry by transporting the plasma up the field lines.
This result suggests that a precise observation of the latitudinal TEC
profile at low latitudes can be used to derive the meridional wind.

Cross-equatorial winds control El Niño diversity and change
06 August 2018
Abstract
Over the past two decades, El Niño events have weakened on average and
their sea surface temperature (SST) anomalies shifted westward towards
the central Pacific. Moreover, the intertropical convergence zone
(ITCZ), which typically migrates southward from its northerly position
during El Niño events, has not crossed the Equator since 1998. The
causes of these changes remain under debate.
Here, using in situ, satellite and atmospheric reanalysis data, we show
they can be related to a multidecadal strengthening of cross-equatorial
winds in the eastern Pacific. This gradual strengthening of meridional
winds is unlikely to be caused by El Niño/Southern Oscillation (ENSO)
changes, and contains signals forced both locally and from outside the
tropical Pacific, probably from the tropical North Atlantic. Coupled
model simulations in which the observed cross-equatorial wind
strengthening is superimposed successfully reproduce the key features of
the recent changes in tropical climate. In particular, the tropical
mean state experiences a ‘La Niña-like’ change, the ENSO amplitude
weakens by about 20%, the centre of the SST anomalies shifts westward
and the ITCZ now rarely crosses the Equator. Thus, cross-equatorial
winds are found to modulate tropical Pacific mean state and variability,
with implications for quantifying projected changes in ENSO under
anthropogenic warming.

Southern Hemisphere Westerlies and Amundsen Sea Low Deepening Over the
20th Century Revealed by Proxy-Data Assimilation
29 November 2021
Abstract
Winds
and pressure over the Southern Ocean are critical to many aspects of
the climate system, but the brevity of climate data in this region makes
it challenging to interpret recent changes. Here, we reconstruct 20th
century sea level pressure and zonal surface wind anomalies over the
Southern Ocean, using data assimilation with a global paleoclimate proxy
database and four climate-model priors. The reconstructions agree well
with instrumental reanalysis products, especially in the circumpolar
westerly and Pacific regions. We observe significant strengthening in
the midlatitude Pacific westerlies, associated with a deepening Amundsen
Sea Low, throughout the 20th century in all four reconstructions. When
the prior includes anthropogenic forcing, we observe poleward-shifting
circumpolar westerlies throughout the 20th century. Our results
highlight the combined roles of natural variability and anthropogenic
forcing, and the zonally asymmetric character of atmospheric circulation
changes at high southern latitudes, with implications for Antarctic ice
sheet change.

The Ocean Has a Fever
August 21, 2023
In
March and April 2023, some earth scientists began to point out that
average sea surface temperatures had surpassed the highest levels seen
in a key data record maintained by NOAA. Months later, they remain at
record levels, with global sea surface temperatures 0.99°C (1.78°F)
above average in July. That was the fourth consecutive month they were
at record levels.
Scientists from NASA have taken a closer look
at why. “There are a lot of things that affect the world’s sea surface
temperatures, but two main factors have pushed them to record heights,”
said Josh Willis, an oceanographer at NASA’s Jet Propulsion Laboratory
(JPL). “We have an El Niño developing in the Pacific, and that’s on top
of long-term global warming that has been pushing ocean temperatures
steadily upward almost everywhere for a century.”
The map above
shows sea surface temperature anomalies on August 21, 2023, when many
areas were more than 3°C (5.4°F) warmer than normal. On that date, much
of the central and eastern regions of the equatorial Pacific were
unusually warm, the signature of a developing El Niño. As has been the
case for weeks, large patches of warm water were also present in the
Northwest Pacific near Japan and the Northeast Pacific near California
and Oregon. Portions of the Indian, Southern, and Arctic Oceans also
showed unusual warmth.
The map is based on data from the
Multiscale Ultrahigh Resolution Sea Surface Temperature (MUR SST)
project, a JPL effort that blends measurements of sea surface
temperatures from multiple NASA, NOAA, and international satellites, as
well as ship and buoy observations. Rather than showing absolute
temperature, the anomaly reflects the difference between the sea surface
temperature on August 21, 2023, and the 2003-2014 average for that day.
The video below, also based on MUR SST data, shows global sea surface
temperatures since April 1, 2023, the period when they have been at
record-breaking levels. The warmest waters appear dark red.
“Over
the long term, we’re seeing more heat and warmer sea surface
temperatures pretty much everywhere,” said Gavin Schmidt, the director
of NASA’s Goddard Institute for Space Studies. “That long-term trend is
almost entirely attributable to human forcing—the fact that we've put
such a huge amount of greenhouse gas in the atmosphere since the start
of the industrial era.”
Schmidt noted that other factors—such as
weather and wind patterns or the distribution of dust and aerosols—have
short-term effects on sea surface temperatures in certain regions, but
they generally have a minor effect on the longer-term global mean.
Previous research shows that as much as 90 percent of the excess heat
that has occurred in recent decades due to increasing greenhouse gas
emissions is absorbed by the ocean, with much of that heat stored near
the surface.
The most important factor that helped push sea
surface temperatures into record territory in 2023 was the evolving El
Niño in the Pacific, according to Willis. He came to that conclusion by
analyzing the timing and intensity of sea surface temperature anomalies
in several regions and comparing them to the global trend.

Bizarre Giant Hexagon on Saturn May Finally Be Explained
September 22, 2015
The huge, mysterious hexagon at Saturn's north pole may finally have an explanation.
The bizarre hexagonal cloud pattern was first discovered in 1988 by scientists reviewing data from NASA's Voyager flybys of Saturn in 1980 and 1981, but its existence was not confirmed until NASA's Cassini spacecraft observed the ringed planet up-close years later.
Nothing like the hexagon has ever been seen on any other world. The structure, which contains a churning storm at its center, is about 20,000 miles (32,000 kilometers) wide, and thermal images show that it reaches roughly 60 miles (100 km) down into Saturn's atmosphere...
The scientists ran computer simulations of an eastward jet flowing in a curving path near Saturn's north pole. Small perturbations in the jet — the kind one might expect from jostling with other air currents — made it meander into a hexagonal shape. Moreover, this simulated hexagon spun around its center at speeds close to that of the real one.
The scenario that best fits Saturn's hexagon involves shallow jets at the cloud level, study team members said. Winds below the cloud level apparently help keep the shape of the hexagon sharp and control the rate at which the hexagon drifts.
Different models, such as ones that involve deeper winds or do not take winds lower down into account, do not match Saturn's hexagon well. For instance, they might result in a six-pointed star, or shapes with more or less than six points, or six pairs of storms arranged in a hexagonal pattern.
Morales-Juberías would now like to compare this new research with models from other research teams to see how these findings hold up. He and his colleagues detailed their findings in June in the journal Astrophysical Journal Letters.

The JIRAM instrument measures heat radiated from the planet at an infrared wavelength of around 5 microns.

Solving the Strange Storms on Jupiter
September 23, 2020
https://www.caltech.edu/about/news/solving-strange-storms-jupiter
At the south pole of Jupiter lurks a striking sight—even for a gas giant planet covered in colorful bands that sports a red spot larger than the earth. Down near the south pole of the planet, mostly hidden from the prying eyes of humans, is a collection of swirling storms arranged in an unusually geometric pattern.
Since they were first spotted by NASA's Juno space probe in 2019, the storms have presented something of a mystery to scientists. The storms are analogous to hurricanes on Earth. However, on our planet, hurricanes do not gather themselves at the poles and twirl around each other in the shape of a pentagon or hexagon, as do Jupiter's curious storms.
Now, a research team working in the lab of Andy Ingersoll, Caltech professor of planetary science, has discovered why Jupiter's storms behave so strangely. They did so using math derived from a proof written by Lord Kelvin, a British mathematical physicist and engineer, nearly 150 years ago.
Ingersoll, who was a member of the Juno team, says Jupiter's storms are remarkably similar to the ones that lash the East Coast of the United States every summer and fall, just on a much larger scale.
"If you went below the cloud tops, you would probably find liquid water rain drops, hail, and snow," he says. "The winds would be hurricane-force winds. Hurricanes on Earth are a good analog of the individual vortices within these arrangements we see on Jupiter, but there is nothing so stunningly beautiful here."
As on Earth, Jupiter's storms tend to form closer to the equator and then drift toward the poles. However, Earth's hurricanes and typhoons dissipate before they venture too far from the equator. Jupiter's just keep going until they reach the poles.
"The difference is that on the earth hurricanes run out of warm water and they run into continents," Ingersoll says. Jupiter has no land, "so there's much less friction because there's nothing to rub against. There's just more gas under the clouds. Jupiter also has heat left over from its formation that is comparable to the heat it gets from the sun, so the temperature difference between its equator and its poles is not as great as it is on Earth."
However, Ingersoll says, this explanation still does not account for the behavior of the storms once they reach Jupiter's south pole, which is unusual even compared to other gas giants. Saturn, which is also a gas giant, has one enormous storm at each of its poles, rather than a geometrically arranged collection of storms.
The answer to the mystery of why Jupiter has these geometric formations and other planets do not, Ingersoll and his colleagues discovered, could be found in the past, specifically in work conducted in 1878 by Alfred Mayer, an American physicist, and Lord Kelvin. Mayer had placed floating circular magnets in a pool of water and observed that they would spontaneously arrange themselves into geometric configurations, similar to those seen on Jupiter, with shapes that depended on the number of magnets. Kelvin used Mayer's observations to develop a mathematical model to explain the magnets' behavior.
"Back in the 19th century, people were thinking about how spinning pieces of fluid would arrange themselves into polygons," Ingersoll says. "Although there were lots of laboratory studies of these fluid polygons, no one had thought of applying that to a planetary surface."
"We wanted to explore the combination of parameters that makes these cyclones stable," says Cheng Li (Phd '17), lead author and 51 Pegasi b postdoctoral fellow at UC Berkeley. "There are established theories that predict that cyclones tend to merge at the pole due to the rotation of the planet and that's what we found in the initial trial runs."
Eventually, however, the team found that a Jupiter-like stable geometric arrangement of storms would form if the storms were each surrounded by a ring of winds that turned in the opposite direction from the spinning storms, or a so-called anticyclonic ring. The presence of anticyclonic rings causes the storms to repel each other, rather than merge.
Ingersoll says the research could help scientists better understand how weather on Earth behaves.
"Other planets provide a much wider range of behaviors than what you see on Earth," he says, "so you study the weather on other planets in order to stress-test your theories."
The paper, titled, "Modeling the Stability of Polygonal Patterns of Vortices at the Poles of Jupiter as Revealed by the Juno Spacecraft," appears in the September 8 Issue of the Proceedings of the National Academy of Sciences. Co-authors are Cheng Li of UC Berkeley, and Harriet Brettle (MS '19) and undergraduate student Alexandra Klipfel, both of Caltech.

Surprises in Venus’ south pole vortex
March 24, 2013
The planet next door, Venus, has two vortices (whirlwinds) above its south pole, and two more above its north pole. Astronomers in the Planetary Science Group of the University of the Basque Country (UPV/EHU) have been closely monitoring the complicated movement of the south pole vortices of slow-rotating Venus. The south pole vortex is a huge double whirlwind the size of Europe. Double? Yes. In the south polar vortex of Venus, there are two main cloud layers separated by a distance of about 20 kilometers (about 12 miles). These scientists announced today (March 24, 2013) that they’ve confirmed the “erratic” movement of air in the double vortex at Venus’ south pole. And, surprisingly they said, each part of the vortex forms a separate “tube,” which “goes its own way.” Itziar Garate-Lopez, head researcher, said in a press release:
We knew it was a long-term vortex; we also knew that it changes shape every day. But we thought that the centers of the vortex at different altitudes formed only a single tube, but that is not so. Each center goes its own way, yet the global structure of the atmospheric vortex does not disintegrate.
The south polar vortex of Venus changes shape every day. The images at the top of the figure show the upper cloud of Venus, 65 km above the planet’s surface. The images at the bottom depict the south polar vortex of Venus 20 km further down showing the vertical extension and variability of the vortex.
Long-term vortices are a frequent phenomenon in the atmospheres of fast-rotating planets, like Jupiter, Saturn and Earth, for example. But Venus rotates very slowly. It rotates only once every 243 Earth-days, more slowly than any other planet in our solar system. Its rotational speed is in contrast to about 24 hours for Earth, 9 hours 56 minutes for Jupiter and 10 hours 39 minutes for Saturn. Still, Venus has permanent vortices in its atmosphere at both poles. One clue to the reason might be that the rotation speed of Venus’ atmosphere is much greater than that of the planet. Traveling at speeds of around 200 meters per second, the atmosphere takes only four Earth days to go all the way around the planet. Garate-Lopez said:
We’ve known for a long time that the atmosphere of Venus rotates 60 times faster than the planet itself, but we didn’t know why. The difference is huge; that is why it’s called super-rotation. And we‘ve no idea how it started or how it keeps going.
Wide-angle camera view from Cassini spacecraft of the north polar region
on Saturn. It shows the central storm clouds inside a larger structure
called the north polar hexagon. This vortex on Saturn is similar to
Earth’s polar vortex where winds blow in a circular pattern.
So the vortices above the poles of Venus appear to be ever-shifting, but permanent. Meanwhile, on Earth, the vortices for each pole are cold-core low-pressure areas that strengthen in the winter and weaken in the summer. They usually span 1,000–2,000 kilometers (620–1,240 miles) in which the air is circulating (in a counter-clockwise fashion in the Northern Hemisphere). Garate-Lopez said:
On the Earth there are seasonal effects and temperature differences between the continental zones and the oceans that create suitable conditions for the formation and dispersal of polar vortices. On Venus there are no oceans or seasons, and so the polar atmosphere behaves very differently.

Bottom line: Astronomers in the Planetary Science Group of the
University of the Basque Country (UPV/EHU) announced today (March 24,
2013) that they’ve confirmed the “erratic” movement of air in the double
vortex at Venus’ south pole. And, surprisingly they said, each part of
the vortex forms a separate “tube,” which “goes its own way.” Planetary
vortices are common for fast-rotating planets like Jupiter, Saturn and
Earth, but Venus rotates very slowly. However, its atmosphere rotates
around the planet 60 times faster than the planet itself!

Space weather
https://en.wikipedia.org/wiki/Space_weather
Space
weather is a branch of space physics and aeronomy, or heliophysics,
concerned with the varying conditions within the Solar System and its
heliosphere. This includes the effects of the solar wind, especially on
the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. Though physically distinct, space weather is analogous to the
terrestrial weather of Earth's atmosphere (troposphere and
stratosphere). The term "space weather" was first used in the 1950s and
popularized in the 1990s. Later, it prompted research into "space
climate", the large-scale and long-term patterns of space weather.

South Atlantic Anomaly: Have astronomers finally explained space's Bermuda Triangle?
January 30, 2022
If
we look skyward we can explore a similar phenomenon dubbed the "Bermuda
Triangle of space" – a vast region above Earth has been known to wreak
havoc on spacecraft that happen to enter the area. In this case, nobody
is claiming that craft are suddenly vanishing into thin air, but the
disruption that's being caused is nevertheless serious, and it poses
great problems for both equipment and astronauts.
The Bermuda
Triangle of space – or the South Atlantic Anomaly (SAA) as it is
formally known – lies above the South Atlantic, stretching from Chile to
Zimbabwe. It sits at the point where the inner Van Allen radiation belt
comes closest to Earth's surface. Here, Earth's magnetic field is
particularly weak.
To explain, Earth has two Van Allen belts – a
couple of doughnut-shaped rings of charged particles that surround our
planet, held in place by Earth's magnetic field. The inner part consists
mainly of high-energy protons and the outer part is mainly electrons.
Because the belts trap the particles that are shooting from the surface
of the sun, they end up protecting the surface of the planet from
harmful radiation.
At the location of the SAA, however, the
particles of solar cosmic rays are not being held back to the same
extent as they are elsewhere above the planet. As a result, solar rays
come as close as 124 miles (200 kilometers (124 miles) to the Earth's
surface and the more intense solar radiation results in an increased
flux of energetic particles in this area.
"I'm not fond of the
[Bermuda Triangle of Space] nickname, but in that region, the lower
geomagnetic field intensity eventually results in a greater
vulnerability of satellites to energetic particles, to the point that
spacecraft damage could occur as they traverse the area," said John
Tarduno, professor of geophysics at the University of Rochester.

Hexagonal clouds are not the mystery behind the Bermuda Triangle
21 Oct 2016
Hexagonal clouds were linked to the Bermuda Triangle but do not solve the mystery of the area in the Atlantic Ocean. This kind of clouds have been seen in the Bermuda Triangle, and although they are rare, they are not uncommon.
The honeycomb cloud patterns open and closed cells can create updrafts and downdrafts and are believed to be responsible for the unusual activity. Nevertheless, it does not solve the mysteries related to the Bermuda Triangle. Hexagonal clouds are usually seen in mid-North Atlantic and the North Pacific during late fall until arely spring. The phenomenon happens when cold, dry air mixes with warm water...

The ‘Bermuda Triangle mystery’ isn’t solved, and this scientist didn’t suggest it was
October 25, 2016
“Scientists
believe the powerful winds reported by radar in the North Sea also
exist below the hexagonal clouds over the Bahamas, and meteorologist
Randy Cerveny thinks they’re connected to a terrifying atmospheric
phenomenon,” the narrator says in the “What on Earth” segment.
Cerveny
goes on to explain that the hexagonal shapes in the clouds could be
formed by “air bombs,” which sounds crazy, but he’s actually just
explaining microbursts — something we have reported on and analyzed many
times.
“If Professor Cerveny is right, and these strange
hexagons are the signature of deadly air bombs,” the segment continues,
“then this satellite image could . . . solve the riddle of the Bermuda
Triangle.”
Microbursts can do extensive damage on land and can
definitely sink ships in the ocean. Could microbursts have sunk a few
ships and downed a few planes in the Bermuda Triangle? Sure. Does this
mean the Bermuda Triangle mystery is real and that we’ve solved it? No —
Cerveny isn’t saying that.
He said he does segments for the show
and typically “either you give the actual explanation, or the straw-man
explanation,” so someone else can come in and knock it down. He said he
offered the microburst explanation as a possibility to knock down.
Instead, the segment offered it as a legitimate explanation.
Cerveny
said he didn’t have an opportunity to see the show and correct it
before it aired. “Nope. That was a surprise,” he said, laughing. “I did
not know what was going on until I saw this. I have no interest in
studying the Bermuda Triangle.”

What's The Real Science Behind The "Bermuda Triangle"?

Have Norwegian geologists solved the mystery of the Bermuda Triangle?
2016
What does a research abstract about craters formed by methane gas eruptions have to do with it?
“Bermuda
Triangle, don’t go too near,” Barry Manilow warns in his saccharine
1980s pop hit named for the enigmatic region in the Atlantic Ocean
legendary for the number of ships and planes that disappear in its
proximity.
Now, some media reports are suggesting that the
mystery behind Mr. Manilow’s admonition may be solved. Pointing to a
Norwegian research abstract that details the discovery of craters at the
bottom of the Barents Sea in the Arctic, British newspapers The Times
and Daily Mail were somehow able to make the leaping proposal that
similar craters caused “notorious” disappearances in the Bermuda
Triangle during the 20th century.
But this isn’t the case. For
one thing, the study, published by geologists at the University of
Norway, focuses solely on craters discovered off of Bear Island, located
above the northern tip of Scandinavia and about 4,000 miles from the
Bermuda Triangle.
Using 3-D seismic imaging, they measured the
craters to be as wide as 3,280 feet in diameter and 131 feet in depth
and suggest that they were caused by methane gas eruptions from oil
accumulated in shallow rocks dating back 250 million years ago.
“The
crater area is still likely to represent one of the largest hot-spots
for shallow marine methane release in the arctic,” they write in a
preliminary summary.
Nowhere in their research, however, is the Bermuda Triangle even mentioned.
“We
have discovered many large craters on the seabed in the central Barents
Sea,” co-author Karin Andreassen said in a statement addressing the
misinforming reports. “We have yet to publish these results, so these
are preliminary. What I can say is that we are not making any links to
the Bermuda Triangle.”
The methane blowouts detailed in their
research, he explained, point to the time period after the last Ice Age
ended – about 11,700 years ago.
And “conditions during the last ice age,” Dr. Andreassen said, “cannot be compared with what we see today.”
The researchers' statement sufficiently dismantles the any association between the craters and the Bermuda Triangle.
But
beyond the geographical irrelevance of the region stretching from Miami
to San Juan, Puerto Rico, and Bermuda, the so-called “mystery” itself
is made up.

‘Burps of Death’ in the Bermuda Triangle?
2016
Researchers
say methane bubbling to the surface of the ocean could explain the
sudden loss of ships in the western North Atlantic.
The Bermuda Triangle doesn’t officially exist. Agencies such as the U.S. Navy and the U.S. Board of Geographic Names do not recognize the region as anything other than an arbitrary area of the western North Atlantic Ocean.
Discussion Ideas
- Some scientists think bubbly gas blowouts from seafloor methane deposits could contribute to “disappearances” associated with the Bermuda Triangle. What is the Bermuda Triangle? Take a look at today’s MapMaker Interactive map for some help.
- The Bermuda Triangle is a loosely defined region of the western North Atlantic Ocean, between Miami, Florida; San Juan, Puerto Rico; and the island of Bermuda.
- Since the early 1960s, the “Bermuda Triangle”
has been a legendary site associated with supernatural disappearances
of ships and planes. This has no basis in fact; ships and planes “vanish in the Bermuda Triangle as often as they vanish from anywhere else.”
- A 1976 NOVA episode was unequivocally dismissive about the concept: “Science does not have to answer questions about the Triangle because those questions are not valid in the first place.” (Way to go, NOVA.)
- If the mystery of the Bermuda Triangle is hype, why do people think planes and ships are more likely to disappear in the area? Take a look at the third bookmark in today’s MapMaker Interactive map for some help. (Don’t be afraid to adjust the transparency levels!)
- The Bermuda Triangle is one of the most hurricane-prone areas of the Atlantic Ocean. Ships and planes are much more likely to encounter strong tropical storms in this region than many others.
- The Gulf Stream, one of the world’s most recognizable ocean currents in the world, flows right through the Bermuda Triangle. Debris from sunken ships or planes may not drift to the bottom of the ocean, but instead be transported north by this extremely powerful current.
- The myth of the Bermuda Triangle is a great story perpetuated by unsupported evidence. Many accounts of missing vessels fail to report the weather conditions at the time of the ships’ disappearance, for example. Other accounts report ships or planes as “missing”—but fail to report their return.
Methane clathrate is an unconventional form of natural gas made of an ice-like lattice of frozen water, which forms a “cage” around molecules of methane. This beautiful sample of methane clathrate was unearthed off the coast of Oregon.
Most methane deposits show up around continental shelves.

Impact of the South Atlantic Anomaly on radiation exposure at flight altitudes during solar minimum
08 June 2023
Abstract
The
South Atlantic Anomaly (SAA) is a geographical region over the South
Atlantic Ocean where the inner Van Allen radiation belt extends down
particularly close to Earth. This leads to highly increased levels of
ionizing radiation and related impacts on spacecraft in Low Earth
Orbits, e.g., correspondingly increased radiation exposure of astronauts
and electronic components on the International Space Station. According
to an urban legend, the SAA is also supposed to affect the radiation
field in the atmosphere even down to the altitudes of civil aviation. In
order to identify and quantify any additional contributions to the
omnipresent radiation exposure due to the Galactic Cosmic Radiation at
flight altitudes, comprehensive measurements were performed crossing the
geographical region of the SAA at an altitude of 13 km in a unique
flight mission—Atlantic Kiss. No indication of increased radiation
exposure was found.

The Bermuda Triangle: A Breeding Ground for Rogue Waves or a Pit of Human Mistakes?
August 2, 2018
Gas bubbles, magnetic anomalies…humans being humans?
People
often talk about weird magnetic anomalies over the Bermuda Triangle,
Boxall said. "There aren't any," he said. There are magnetic anomalies
in the world that have to do with the Earth's mantle moving beneath the
crust, but the nearest one is about 1,000 miles [1,600 km] south, off
the coast of Brazil — a long way away from the Bermuda Triangle, he
said.
Another theory has to do with pockets of explosive methane
gas that could, due to some disturbance, float up toward the water's
surface and cause the water to be less dense than the ship, leading the
ship to sink. However, no experiment to date has been able to prove that
this is possible, Boxall said.
"Theoretically, it could be
happening, but there are lots of places in the world where this can
happen," not just in the Bermuda Triangle, Boxall said. Instead, he
thinks the most common cause for the mysterious vanishings is human
error. [The 20 Most Mysterious Shipwrecks Ever]
The famous
disappearance of Flight 19 — five U.S. Navy aircraft that vanished
during a training mission in 1945 — that led one journalist in 1964 to
give the area its current name, probably occurred because the crew got
lost and ran out of fuel, Boxall said.
About a third of all
registered and privately owned ocean craft in the U.S. are in the states
and islands of the Bermuda Triangle area, he said. And according to the
most recent 2016 figures from the Coast Guard, 82 percent of incidents
in this area that year involved people who had no formal training or
experience of being at sea, he added.
"So, you take a third of
the entire boating population of the U.S., you dump them in the Bermuda
Triangle," and what you get is mysterious vanishings, Boxall said. You
don't need any licensing or specific equipment like radios or navigation
maps to take a boat to sea, he added.
"A number of times,
working at sea, we've come across people who are navigating using a road
map, who are relying on their mobile phones as their means of
communication, discovering … you get 30 miles offshore [and] you lose
the signal," Boxall said.
In addition, "environmental
considerations could explain many, if not most, of the disappearances,"
NOAA wrote on its website. "The ocean has always been a mysterious place
to humans, and when foul weather or poor navigation is involved, it can
be a very deadly place."
NOAA also says the area could be prone
to accidents because of the Gulf Stream, a strong and fast ocean current
that can cause "rapid, sometimes violent, changes in weather," and
shallow waters around the Caribbean islands that can prove fatal for
ships.
"You can extend the Bermuda Triangle to ever bigger
areas…what you'll find is that the Bermuda Triangle covers the entire
globe," Boxall said. "Rogue waves can hit lots of different places,
methane bubbles can hit lots of different places, and wherever you get a
high concentration of amateurs without any experience you're going to
get a high concentration of mysterious disappearances."
But, you
know, maybe it is aliens capturing unsuspecting humans using vortexes
that lead straight into their laboratories that they've set up in the
lost city of Atlantis.

The Atlantic Ocean could soon be closed off by a ring of furious volcanoes
March 2024
The Ring of Fire is one of the most iconic geological features in the world.
Stretching
some 40,000 km along the Pacific Ocean, it is home to 75 per cent of
the Earth’s volcanoes and 90 per cent of its earthquakes, making it the
planet’s greatest hotbed of violent seismic events.
And yet, this
extraordinary area may be faced with some competition in the dramatic
tectonic stakes, with experts warning that the Atlantic could eventually
begin to close and form a Ring of Fire of its own.
For an ocean
such as the Atlantic to stop growing and shut itself off, new subduction
zones must form within it – areas where one tectonic plate pushes
another down into the mantle below.
The heat from the mantle then
melts this rock, transforming it into magma. And the abundance of magma
near to the Earth’s surface creates the perfect conditions for volcanic
activity, as National Geographic notes.

Continental Drift versus Plate Tectonics
A
scientific idea that was initially ridiculed paved the way for the
theory of plate tectonics, which explains how Earth’s continents move.
https://education.nationalgeographic.org/resource/continental-drift-versus-plate-tectonics/
______________
Continental drift
https://en.wikipedia.org/wiki/Continental_drift
Continental
drift is the hypothesis, originating in the early 20th century, that
Earth's continents move or drift relative to each other over geologic
time. The hypothesis of continental drift has since been validated and
incorporated into the science of plate tectonics, which studies the
movement of the continents as they ride on plates of the Earth's
lithosphere.
The speculation that continents might have "drifted"
was first put forward by Abraham Ortelius in 1596. A pioneer of the
modern view of mobilism was the Austrian geologist Otto Ampferer. The
concept was independently and more fully developed by Alfred Wegener in
his 1915 publication, "The Origin of Continents and Oceans". However, at
that time the hypothesis was rejected by many for lack of any motive
mechanism. The English geologist Arthur Holmes later proposed mantle
convection for that mechanism.

Plume–ridge interactions: ridgeward versus plate-drag plume flow
2023
Abstract
The
analysis of mid-ocean ridges and hotspots that are sourced by
deep-rooted mantle plumes allows us to get a glimpse of mantle structure
and dynamics. Dynamical interaction between ridge and plume processes
have been widely proposed and studied, particularly in terms of
ridgeward plume flow. However, the effects of plate drag on
plume–lithosphere and plume–ridge interaction remain poorly understood.
In particular, the mechanisms that control plume flow towards vs. away
from the ridge have not yet been systematically studied. Here, we use 2D
thermomechanical numerical models of plume–ridge interaction to
systematically explore the effects of (i) ridge-spreading rate, (ii)
initial plume head radius and (iii) plume–ridge distance. Our numerical
experiments suggest two different geodynamic regimes: (1) plume flow
towards the ridge is favored by strong buoyant mantle plumes, slow
spreading rates and small plume–ridge distances; (2) plume drag away
from the ridge is in turn promoted by fast ridge spreading for
small-to-intermediate plumes and large plume–ridge distances. We find
that the pressure gradient between the buoyant plume and spreading ridge
at first drives ridgeward flow, but eventually the competition between
plate drag and the gravitational force of plume flow along the base of
the sloping lithosphere controls the fate of plume (spreading towards
vs. away from the ridge). Our results highlight that fast-spreading
ridges exert strong plate-dragging force, which sheds new light on
natural observations of largely absent plume–lithosphere interaction
along fast-spreading ridges, such as the East Pacific Rise.

Divergent Plate Boundaries
Divergent
plate boundaries are locations where plates are moving away from one
another. This occurs above rising convection currents. The rising
current pushes up on the bottom of the lithosphere, lifting it and
flowing laterally beneath it. This lateral flow causes the plate
material above to be dragged along in the direction of flow. At the
crest of the uplift, the overlying plate is stretched thin, breaks and
pulls apart.

70 million years of seafloor spreading and magmatism in the South Atlantic
2021
Highlights
70 million years of crust from one spreading center are examined.
The relationships between M, RMS roughness, and spreading rate are quantified.
The coefficients of determination for all relationships are small.
The spreading center has changed from an axial high to valley twice in 70 myrs.
Abstract
A
basic tenet of seafloor spreading is the need to spatially accommodate
the magnitude of lateral spreading. As new spreading proceeds and crust
is transported away from the spreading axis, the space created is filled
by both the magmatic accretion of new oceanic crust and the brittle
stretching of that crust by extensional faults. The ratio between the
magmatism and faulting, referred to as M, is dynamically related to the
rate of spreading and the topographic roughness of the generated crust.
Here we use a multichannel seismic dataset recently collected in the
South Atlantic Ocean to examine how the relationships between spreading
rate, M, and topographic roughness have changed over 70 million years of
crustal ages all created at one spreading segment. We frequency filter
the topographic profile of the top of the igneous crust to remove long
wavelength signal and determine the best window length for analysis. We
then use a moving window to quantify how M and the root mean square of
topographic roughness vary across the age transect. Qualitatively and
quantitatively, we find spreading rate and M are positively correlated
while M and spreading rate are negatively correlated with the
topographic roughness of the crust. We are able to expand the age and
length scale of an analysis of M by an order of magnitude compared to
previous studies. Our analysis also finds that the spreading center in
the South Atlantic has likely alternated between an axial high and axial
valley twice in the past.

Evidence for a Global Slowdown in Seafloor Spreading Since 15 Ma
25 March 2022
Abstract
The
rate of ocean-crust production exerts control over sea level, mantle
heat loss, and climate. Different strategies to account for incomplete
seafloor preservation have led to differing conclusions about how much
production rates have changed since the Cretaceous, if at all. We
construct a new global synthesis of crust production along 18 mid-ocean
ridges for the past 19 Myr at high temporal resolution. We find that the
global production rate during 6–5 Ma was only 69%–75% of the 16–15 Ma
interval. The reduction in crust production is mostly due to slower
seafloor spreading along almost all ridge systems. While the total ridge
length has varied little since 19 Ma, some fast-spreading ridges have
grown shorter and slow-spreading ridges grown longer, amplifying the
spreading-rate changes. Our production curves represent a new data set
for investigating the forces driving plate motions and the role of
tectonic degassing on climate.

The Mystery of the World’s Largest and Deepest Gravity Hole
November 3, 2023
The sea level here is hundreds of feet lower than the rest of the ocean.
Dear
Indian Ocean, please don’t take offense, but: Why is your gravity hole
so big? That question had been baffling scientists ever since the hole
was discovered back in 1948. Now a team from the Indian Institute of
Science (IISc) thinks they have found the answer: The “hole” in the
Indian Ocean is caused by fragments from the sunken floor of another,
much older ocean.
There’s nothing mysterious per se about
gravitational variation, which corresponds to differences in the density
of the subsurface (and submarine) layers of rock. What was unexplained,
was the size and amplitude of the anomaly in the Indian Ocean.
More air than water
The
gravity hole is centered about 1,200 kilometers (750 miles) southwest
of Kanyakumari (aka Cape Comorin), the southernmost tip of the Indian
subcontinent. The circular depression in the ocean has an area of about 3
million square kilometers (1.2 million square miles), which is almost
the size of India itself. Due to lower local gravity, the sea level in
the IOGL is up to 106 meters (348 feet) lower than the global average.
That adds up to a huge volume of air where there should be water. A back
of the envelope calculation suggests that, due to the anomaly, about
100 cubic kilometers (25 cubic miles) of water is being displaced.
The
anomaly was discovered by Felix Andries Vening Meinesz, a Dutch
geophysicist who had invented a device to measure gravity at sea. (It
was nicknamed the “Golden Calf,” because of its color and because
sailors on submarines carrying the instrument had to remain motionless
in their bunk during measurements, a nuisance for which they received
extra pay.)
As a pioneer of submarine gravimetry, Vening Meinesz
spent much of his career roaming the oceans in submarines and research
vessels. He discovered several anomalies in Earth’s gravitational field,
which he attributed to plate tectonics, none larger or stronger than
the one in the Indian Ocean.
The eminent Dutchman—one of his
research fellows was the geologist B.G. Escher, the brother of the
graphic artist M.C. Escher—was thinking in the right direction, but his
era lacked the computing power to pinpoint a more proximate cause. The
actual cause of the IOGL remained unknown until last May, when the
journal Geophysical Research Letters published a study by IISc
researchers.
Starting the clock 140 million years ago, the IISc
team ran various simulations through a supercomputer to explore how
tectonic and volcanic forces shaped the world as we know it. The models
that produced a gravity hole closely resembling the actual IOGL all had
one thing in common: low-density magma plumes rising up to displace
higher-density material, weakening the area’s gravity.

Rethinking Earth’s Surface: Geoscientists Discover Hidden Faults of the Pacific Plate
March 7, 2024
Research
indicates that the Pacific Plate is being torn apart at undersea
plateaus across the ocean, due to the weight of the oceanic plate
subducting along the Western Pacific Ring of Fire.
Recent
research conducted by geoscientists from the University of Toronto is
refining the long-standing model of plate tectonics, which suggests that
the oceanic plates are inflexible as they glide over the Earth’s
mantle.
Instead, the researchers found the Pacific Plate is
scored by large undersea faults pulling it apart. The newly discovered
faults, some thousands of meters deep and hundreds of kilometers long,
are the result of enormous forces within the plate tugging it westward.
The
researchers describe their findings in a paper published in the journal
Geophysical Research Letters. The authors include Erkan Gün, a
postdoctoral fellow, and Professor Russell Pysklywec in the Department
of Earth Sciences in the Faculty of Arts & Science at U of T, Phil
Heron, an assistant professor in the Department of Physical &
Environmental Sciences at University of Toronto Scarborough, as well as
researchers from the Eurasia Institute of Earth Sciences, Istanbul

INTRODUCTION - 500 Million Years of Florida Geology
200 Million Years of Undersea Calcium Carbonate Deposition
It is upon these very old, African-born basement rocks that the sedimentary rocks of the Florida Platform would
start to accumulate. Deep layers of carbonate rock—predominantly limestones and dolostones composed of the
mineral calcium carbonate—built up over the next 200 million years to create Florida’s flat-topped, “carbonate
platform” structure. These rock layers, two to three miles thick in some places, are a result of the near-constant
deposition of calcium carbonate (CaCO3) that occurred in the warm ocean shallows that surrounded and very
often completely submerged ancient Florida. As marine organisms lived and died in the shallow seas, their skeletal
remains became concentrated, compacted, and gradually hardened (lithified) into a complex subsurface
stratigraphy of sedimentary rock formations, whose differences in depth, location, and composition reflect
Florida’s fascinating formational history.

NASA Researchers Track Slowly Splitting ‘Dent’ in Earth’s Magnetic Field
Aug 17, 2020
A small but evolving dent in Earth’s magnetic field can cause big headaches for satellites.
Earth’s
magnetic field acts like a protective shield around the planet,
repelling and trapping charged particles from the Sun. But over South
America and the southern Atlantic Ocean, an unusually weak spot in the
field – called the South Atlantic Anomaly, or SAA – allows these
particles to dip closer to the surface than normal. Particle radiation
in this region can knock out onboard computers and interfere with the
data collection of satellites that pass through it – a key reason why
NASA scientists want to track and study the anomaly.
The South
Atlantic Anomaly is also of interest to NASA’s Earth scientists who
monitor the changes in magnetic field strength there, both for how such
changes affect Earth’s atmosphere and as an indicator of what’s
happening to Earth’s magnetic fields, deep inside the globe.
Currently,
the SAA creates no visible impacts on daily life on the surface.
However, recent observations and forecasts show that the region is
expanding westward and continuing to weaken in intensity. It is also
splitting – recent data shows the anomaly’s valley, or region of minimum
field strength, has split into two lobes, creating additional
challenges for satellite missions.
A host of NASA scientists in
geomagnetic, geophysics, and heliophysics research groups observe and
model the SAA, to monitor and predict future changes – and help prepare
for future challenges to satellites and humans in space.

High Sea Level Along U.S. Atlantic Coast Due To Ocean Current And Wind Changes
August 31, 2009
Persistent
winds and a weakened current in the Mid-Atlantic contributed to higher
than normal sea levels along the Eastern Seaboard in June and July,
according to a new NOAA technical report.
After observing water
levels six inches to two feet higher than originally predicted, NOAA
scientists began analyzing data from select tide stations and buoys from
Maine to Florida and found that a weakening of the Florida Current
Transport—an oceanic current that feeds into the Gulf Stream—in addition
to steady and persistent Northeast winds, contributed to this anomaly.
“The
ocean is dynamic and it’s not uncommon to have anomalies,” said Mike
Szabados, director of NOAA’s Center for Operational Oceanographic
Products and Services.
“What made this event unique was its breadth, intensity and duration.”
The
highest atypical sea levels occurred closer to where the anomaly formed
in the Mid-Atlantic, where cities like Baltimore, Md., at times
experienced extreme high tides as much as two feet higher than normal.
Data
from NOAA’s National Water Level Observation Network tide stations,
Atlantic Oceanographic and Meteorological Laboratory, and National Data
Buoy Center, are published in the report.
Impacts of the event
were amplified by the occurrence of a perigean-spring tide, the natural
timing of the season and month when the moon is closest to the Earth and
its gravitational pull heightens the elevation of the water.
The combined effects of this tide with the sea level anomaly produced minor flooding on the coast.
“The
report is a good first assessment,” said NOAA Oceanographer William
Sweet, Ph.D. “However, NOAA, with our academic partners, should continue
to investigate the broader causes behind the event. Further analysis is
needed to fully understand what is driving the patterns we observed.”

Critical Atlantic Ocean current system is showing early signs of collapse, prompting warning from scientists
February 9, 2024
A
crucial system of ocean currents may already be on course to collapse,
according to a new report, with alarming implications for sea level rise
and global weather — leading temperatures to plunge dramatically in
some regions and rise in others.
Using exceptionally complex and
expensive computing systems, scientists found a new way to detect an
early warning signal for the collapse of these currents, according to
the study published Friday in the journal Science Advances. And as the
planet warms, there are already indications it is heading in this
direction.
The Atlantic Meridional Overturning Circulation (the
AMOC) — of which the Gulf Stream is part — works like a giant global
conveyor belt, taking warm water from the tropics toward the far North
Atlantic, where the water cools, becomes saltier and sinks deep into the
ocean, before spreading southward.
The currents carry heat and
nutrients to different areas of the globe and play a vital role in
keeping the climate of large parts of the Northern Hemisphere relatively
mild.
For decades, scientists have been sounding the alarm on
the circulation’s stability as climate change warms the ocean and melts
ice, disrupting the balance of heat and salt that determines the
currents’ strength.
While many scientists believe the AMOC will
slow under climate change, and could even grind to a halt, there remains
huge uncertainty over when and how fast this could happen. The AMOC has
only been monitored continuously since 2004.

Scientists warn of current ‘tipping point’ in Atlantic Ocean; ‘significant’ effects on climate
February 10, 2024
A
critical system of Atlantic Ocean currents may be approaching collapse,
which scientists warn will have a dangerous impact on our global
climate.
The Atlantic Meridional Overturning Circulation (AMOC),
which “effectively transports heat and salt through the global ocean,”
has recently shown signs of trending toward a crucial “tipping point”
according to a study published Friday in the journal Science Advances.
Scientists
have been warning of the potential collapse for decades, as the
currents’ strength has been weakened by rising temperatures which affect
the system’s balance of heat and salt.
While the study offers no
timetable for when a collapse could occur — the AMOC has only been
closely observed since 2004 — it predicts devastating effects in
particular for Euorpe and the Amazon rainforest.

The polar vortex is acting up

Arctic. So far, this disruption of the polar vortex has been minor,
falling short of the wind reversal (west-to-east → east-to-west) that
defines a major sudden stratospheric warming. Our post last week
explained that this major warming event has been elusive so far due to
the lack of waves propagating from the troposphere below to the main
level of the stratospheric polar vortex. Minor warmings themselves are
not unexpected. Nor are they generally expected to be felt all the way
down at the surface.
But what makes the stratosphere’s current
behavior unexpected and somewhat rare is that the polar vortex seems to
be more disrupted at the lower levels, closer to the
stratosphere-troposphere boundary. For more than a week, high pressure
has been sitting in the troposphere over Greenland [footnote #1]. It’s
possible that the recent minor stratosphere warming reinforced this
Greenland high pressure, which then drove a wedge into the stretched-out
polar vortex in the lowest part of the stratosphere, splitting it into
two lobes.
This lower stratosphere disturbance has been
affecting the winds above it and looks to become just strong enough to
fully reverse the winds of the polar vortex in the mid-stratosphere. A
major sudden stratospheric warming is forecast to likely occur tomorrow.
Normally, that’s when the excitement about whether we’ll see any
surface impacts begins, as changes in the polar vortex communicate their
way down to the lower stratosphere and sometimes the troposphere. But
since the lower stratosphere has been perturbed for a while now, we’ve
already been on the lookout for changes in the troposphere...

Deadly coral disease in Florida, Caribbean may be transported in ship hulls, study finds
November 16, 2022
A new study suggests that ships may be spreading a deadly coral disease across Florida and the Caribbean. The findings by scientists at the University of Miami (UM) Rosenstiel School of Marine, Atmospheric, and Earth Science could help establish testing and treatment methods to mitigate the risk of further disease spread.
Stony coral tissue loss disease, or SCTLD, was first observed near Miami in 2014 and has since spread throughout all of Florida's Coral Reef and into the Caribbean, including in waters off Jamaica, St. Maarten, U.S. Virgin Islands, and Belize.
Researchers suggest that transport through ship hulls, where the vessel take on ballast water in one region to keep it stable and release it at a different port, may have contributed to disease spread.

Florida's Coral Reef Disease Outbreak
Scientists, policy makers, and the public are responding to a disease event affecting the continental United States' only living barrier reef.
Florida's Coral Reef is experiencing a multi-year outbreak of stony coral tissue loss disease. While disease outbreaks are not uncommon, this event is unique due to its large geographic range, extended duration, rapid progression, high rates of mortality and the number of species affected. The disease is thought to be caused by bacteria and can be transmitted to other corals through direct contact and water circulation. Researchers are working to identify potential pathogens and relationships with environmental factors, strategies to treat diseased colonies, and identify genotypes of corals that are resistant to the disease.

Stony coral tissue loss disease accelerated shifts in coral composition and declines in reef accretion potential in the Florida Keys
25 October 2023
Outbreaks of coral disease have been a dominant force shaping western
Atlantic coral-reef assemblages since the late 1970s. Stony coral tissue
loss disease (SCTLD) is nonetheless having an unprecedented impact in
the region. Whereas numerous studies over the last decade have worked to
characterize this novel pathogen and its impacts on coral populations,
few have quantified its functional effects on reef ecosystems. Of
particular importance is how SCTLD may be impacting the essential
reef-accretion process and the myriad ecosystem services it supports.
Here, we evaluated the impact of SCTLD on reef-accretion potential by
estimating carbonate budgets and taxon-level carbonate production at 43
sites throughout the Florida Keys from 2016−2022. Average regional
reef-accretion potential declined from an already low, but positive rate
of 0.30 ± 0.16 mm y-1 (mean ± standard error) in 2016 before the disease was first observed, to a state of accretionary stasis (0.08 ± 0.12 mm y-1)
by 2022. This 70% relative decline in reef-accretion potential was
driven by the loss of reef-building corals, with significant decreases
in carbonate production by massive taxa including Colpophyllia natans, Montastraea cavernosa, Pseudodiploria strigosa, Orbicella spp., and Siderastrea siderea, and increasing contributions from less susceptible, weedy taxa including Millepora spp., Agaricia spp., and Porites astreoides.
In general, changes in taxon-level carbonate production following the
SCTLD outbreak mirror long-term shifts in reef assemblages in response
to previous stressors. One striking exception, however, is S. siderea,
which had become increasingly dominant in recent decades, but declined
significantly in response to SCTLD. Overall, by further decimating the
already depauperate reef-building coral populations in the Florida Keys,
SCTLD has caused a functionally significant shift in the composition of
Florida’s coral-reef assemblages and accelerated the loss of regional
reef-building capacity. The dire impacts of the disease in south Florida
may serve as an early warning that the persistence of the invaluable
ecological and socioeconomic functions coral reefs provide will be
increasingly threatened throughout the western Atlantic in the aftermath
of SCTLD.

Extreme Ocean Temperatures Are Affecting Florida’s Coral Reef
August 18, 2023
Since April 2023, NOAA has been monitoring a steady rise in ocean temperatures, which is resulting in unprecedented heat stress conditions in the Caribbean basin, including waters surrounding Florida and the Gulf of Mexico. On Thursday, August 17, 2023, NOAA scientists provided a briefing on how these record-breaking warm ocean temperatures have stressed, bleached, and in some cases, killed corals within the 3,800 square miles of the Florida Keys National Marine Sanctuary.
Coral reefs are often referred to as the "rainforests of the sea," due to their incredible biodiversity and ecological importance. They provide vital benefits as part of marine ecosystems by sustaining habitats for marine life, buffering the harmful impacts of storms on coastal communities, and supporting local economies through tourism and fishing.
According to the briefing, a large-scale heat stress and coral bleaching event is underway, impacting two ocean basins and multiple countries. Five countries in the Eastern Tropical Pacific have confirmed coral bleaching, including Mexico, El Salvador, Costa Rica, Panama, and Columbia. Seven countries/territories/states in the Atlantic have confirmed bleaching as well, including Florida, Puerto Rico, the U.S. Virgin Islands, Mexico (both sides of the Yucatan), Panama, Belize, and Cuba.
Throughout the Caribbean and Atlantic, sea surface temperatures are as high or higher than ever before in satellite records, and heat stress has developed five to six weeks earlier than ever seen in the record.
Essentially, corals around Florida are experiencing extreme levels of heat stress that have never been recorded before. All of the Florida Keys are at Alert Level 2 for bleaching conditions, which means severe, widespread bleaching and significant mortality are likely. Some sites have already been exposed to two times greater the amount of heat stress than when mortality is expected to begin, and so far, the most extreme heat stress is in the lower and middle Florida Keys.

Hot seawater killed most of cultivated coral in Florida Keys in setback for restoration effort
February 16, 2024
Record hot seawater killed more than three-quarters of human-cultivated coral that scientists had placed in the Florida Keys in recent years in an effort to prop up a threatened species that’s highly vulnerable to climate change, researchers discovered.
Researchers from the National Oceanic and Atmospheric Administration this week returned to five reefs where they planted staghorn and elkhorn coral, both classified as threatened in the endangered species list, to see how the repopulated critters had survived prolonged water temperatures in the 90s (30s Celsius) last summer and fall. Most of them didn’t. They saw widespread death in both repopulated and wild coral on five Florida Keys reefs.

Probiotics May Help Corals Fight a Dangerous Disease Off Florida’s Coast
April 6, 2023
The new treatment shows promise in lab experiments
It begins as a pale spot on an otherwise colorful mass of coral that the average snorkeler might not give a second glance. But to the trained scientific eye, that spot is a lesion that can be a disturbing harbinger of swift and complete destruction, even of healthy corals. Unfortunately biologists working in Florida and Caribbean waters have seen far too much of stony coral tissue loss disease (SCTLD), a persistent and widespread pathogen that is leaving an ever-growing trail of dead, white coral in its wake.
“It’s really devastating,” says Valerie Paul, head scientist at the Smithsonian Marine Station at Fort Pierce, Florida. “It can kill coral that’s hundreds of years old in a month.”
The remaining live tissue on this great star coral (Montastraea cavernosa)
colony in Florida is being destroyed by stony coral tissue loss
disease. The bright white margin surrounding the dark-brown, living
coral tissue is where the coral is bleaching and dying due to the
disease.

What Exactly Is a Red Tide?
August 2018
Drifting
throughout the ocean, invisible to the naked eye, are innumerable
microscopic algae. They come in many shapes and sizes—some geometrically
beautiful, like the diatoms, and others, like the dinoflagellates, swim
in a distinctive whirling pattern. These tiny algae are essential
components to ocean life as they fuel the food web by harnessing light
energy from the sun. But when supplied with excess nutrients, they can
multiply uncontrollably, becoming an unwanted mass commonly called a
“red tide” that smothers nearby ocean life.
This massive growth
of algae can become harmful to both the environment and humans, which is
why scientists often refer to them as harmful algal blooms or HABs.
When nutrients from inland areas flow down rivers and arrive in the
ocean they supply a nutritious feast for algae, causing them to rapidly
grow. This can happen naturally as rivers flood and bring nutrient-rich
soil from forests and grasslands, but it can also happen when fertilizer
and excrement from livestock travel down those same waterways, or when
coastal development leads to excess erosion. Some algae species, like
the dinoflagellate Karenia brevis, color the ocean surface a deep red,
inspiring the name “red tide.” But not all red tides are red and not all
of them even become dense enough to color the water. There are also
“brown tides” which can be damaging as well.
The sea of red in the waves is caused by an algae called Karenia brevis.
Not only do red tides create temporarily toxic oceans, they can also deplete the water of dissolved oxygen, causing a phenomenon known as a dead zone. When the algae die, they become a feast for microbes, like bacteria. These microbes, like animals, require oxygen, so as they feed on the dead algae they also multiply and consume much of the oxygen in the ocean. This leaves little available for fish and other creatures that breathe underwater. When the ocean becomes depleted of oxygen, fish can die en masse—leaving the ocean surface covered in floating, dead fish for as far as the eye can see.
Red tides are seasonal and often peak in the late summer when ocean conditions are the best for algae growth, however, off the coast of Florida they have been known to last for up to 18 months at a time. Although a natural occurrence (Spanish explorers remarked on the Florida red tides in the 1500s), studies suggest that harmful algal blooms are increasing in frequency, likely due to climate change and nutrient pollution from farming and landscaping.
But this does not mean the situation is hopeless—through concerted efforts in cleaning rivers and coastlines of excess nutrients, communities can curb the spread of these increasingly frequent red tides. Following a sudden population growth in the 1950s, Tampa Bay became covered in a thick mat of algae as mangroves were cleared and polluted water was dumped straight into the bay. Now, after over 40 years of restoration, the bay is cleaner than ever and the story of the community that came together to restore their waterways proves that recovery is possible.
Dinoflagellates are major producers of oxygen in the ocean (and freshwater). But some species can grow out of control, causing a red tide.
A satellite image of chlorophyll concentrations (the molecule used in photosynthesis) shows the harmful algae bloom in the southwestern part of Florida.

Harmful algal bloom
A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, mechanical damage to other organisms, or by other means. HABs are sometimes defined as only those algal blooms that produce toxins, and sometimes as any algal bloom that can result in severely lower oxygen levels in natural waters, killing organisms in marine or fresh waters. Blooms can last from a few days to many months. After the bloom dies, the microbes that decompose the dead algae use up more of the oxygen, generating a "dead zone" which can cause fish die-offs. When these zones cover a large area for an extended period of time, neither fish nor plants are able to survive. Harmful algal blooms in marine environments are often called "red tides".

Exposure to Aerosolized Algal Toxins in South Florida Increases Short- and Long-Term Health Risk in Drosophila Model of Aging
2020
Abstract
Harmful algal blooms (HABs) are a rising health and environmental
concern in the United States, particularly in South Florida. Skin
contact and the ingestion of contaminated water or fish and other
seafood have been proven to have severe toxicity to humans in some
cases. However, the impact of aerosolized HAB toxins is poorly
understood. In particular, knowledge regarding either the immediate or
long-term effects of exposure to aerosolized cyanotoxins produced by
freshwater blue-green algae does not exist. The aim of this study was to
probe the toxicity of aerosolized cyanobacterial blooms using Drosophila melanogaster
as an animal model. The exposure of aerosolized HABs at an early age
leads to the most severe long-term impact on health and longevity among
all age groups. Young groups and old males showed a strong acute
response to HAB exposure. In addition, brain morphological analysis
using fluorescence imaging reveals significant indications of brain
degeneration in females exposed to aerosolized HABs in early or late
stages. These results indicate that one-time exposure to aerosolized HAB
particles causes a significant health risk, both immediately and in the
long-term. Interestingly, age at the time of exposure plays an
important role in the specific nature of the impact of aerosol HABs. As
BMAA and microcystin have been found to be the significant toxins in
cyanobacteria, the concentration of both toxins in the water and
aerosols was examined. BMAA and microcystin are consistently detected in
HAB waters, although their concentrations do not always correlate with
the severity of the health impact, suggesting the potential contribution
from additional toxins present in the aerosolized HAB. This study
demonstrates, for the first time, the health risk of exposure to
aerosolized HAB, and further highlights the critical need and importance
of understanding the toxicity of aerosolized cyanobacteria HAB
particles and determining the immediate and long-term health impacts of
HAB exposure.

Pollution Verified in Most of Southwest Florida Area’s Prized Water Bodies
2021
What’s been long suspected now is official: Southwest Florida’s most cherished waters are in trouble.
From
Charlotte Harbor south to San Carlos Bay, a draft state report shows
widespread pollution from the fertilizer nitrogen and the algae
byproduct, chlorophyll. Many of them also contain unhealthy levels of
fecal bacteria. Even the water in the J.N. “Ding” Darling National
Wildlife Refuge on Sanibel Island is tainted.
For years, the
Sanibel-Captiva Conservation Foundation has been sampling the water
around its islands, and the nonprofit is now sounding the alarm, joined
by other water quality advocates.
The latest report includes most
of the water bodies along the Gulf of Mexico including the barrier
islands and the coast – the places that power the region’s $3 billion
tourism industry.
It’s an industry still traumatized by 2018’s
devastating dual toxic blooms of red tide and cyanobacteria. The
microorganisms responsible for both can be fed by nutrient pollution.

Algal bloom
https://en.wikipedia.org/wiki/Algal_bloom
An
algal bloom or algae bloom is a rapid increase or accumulation in the
population of algae in freshwater or marine water systems. It is often
recognized by the discoloration in the water from the algae's
pigments.[1] The term algae encompasses many types of aquatic
photosynthetic organisms, both macroscopic multicellular organisms like
seaweed and microscopic unicellular organisms like cyanobacteria.[2]
Algal bloom commonly refers to the rapid growth of microscopic
unicellular algae, not macroscopic algae.[3] An example of a macroscopic
algal bloom is a kelp forest.[2]
Algal blooms are the result of a
nutrient, like nitrogen or phosphorus from various sources (for example
fertilizer runoff or other forms of nutrient pollution), entering the
aquatic system and causing excessive growth of algae. An algal bloom
affects the whole ecosystem.
Consequences range from the benign
feeding of higher trophic levels to more harmful effects like blocking
sunlight from reaching other organisms, causing a depletion of oxygen
levels in the water, and, depending on the organism, secreting toxins
into the water. Blooms that can injure animals or the ecology,
especially those blooms where toxins are secreted by the algae, are
usually called "harmful algal blooms" (HAB), and can lead to fish
die-offs, cities cutting off water to residents, or states having to
close fisheries. The process of the oversupply of nutrients leading to
algae growth and oxygen depletion is called eutrophication.
Algal
and bacterial blooms have persistently contributed to mass extinctions
driven by global warming in the geologic past, such as during the
end-Permian extinction driven by Siberian Traps volcanism and the biotic
recovery following the mass extinction.

Unethical human experimentation in the United States
https://en.wikipedia.org/wiki/Unethical_human_experimentation_in_the_United_States
1950s
In
1950, to conduct a simulation of a biological warfare attack, the U.S.
Navy sprayed large quantities of the bacteria Serratia marcescens –
considered harmless at the time – over the city of San Francisco during a
project called Operation Sea-Spray. Numerous citizens contracted
pneumonia-like illnesses, and at least one person died as a
result. The family of the person who died sued
the government for gross negligence, but a federal judge ruled in favor
of the government in 1981. Serratia tests were continued until at
least 1969.
Also in 1950, Dr. Joseph Stokes of the University
of Pennsylvania deliberately infected 200 female prisoners with viral
hepatitis.
From the 1950s to 1972, mentally disabled children
at the Willowbrook State School in Staten Island, New York, were
intentionally infected with viral hepatitis, for research whose purpose
was to help discover a vaccine. From 1963 to 1966, Saul Krugman of
New York University promised the parents of mentally disabled children
that their children would be enrolled into Willowbrook in exchange for
signing a consent form for procedures that he claimed were
"vaccinations". In reality, the procedures involved deliberately
infecting children with viral hepatitis by feeding them an extract made
from the feces of patients infected with the disease.
In
1952, Chester M. Southam, a Sloan-Kettering Institute researcher,
injected live cancer cells, known as HeLa cells, into prisoners at the
Ohio State Penitentiary and cancer patients. Also at Sloan-Kettering,
300 healthy females were injected with live cancer cells without being
told. The doctors stated that they knew at the time that it might cause
cancer.
In 1953, Dr. Frank Olson and several other colleagues
were unknowingly dosed with LSD as part of a CIA experiment, MK-ULTRA.
Olson died nine days later after falling to his death from a hotel
window under suspicious circumstances.
The San Francisco
Chronicle, December 17, 1979, p. 5 reported a claim by the Church of
Scientology that the CIA conducted an open-air biological warfare
experiment in 1955 near Tampa, Florida, and elsewhere in Florida with
whooping cough bacteria. It was alleged that the experiment tripled the
whooping cough infections in Florida to over one-thousand cases and
caused whooping cough deaths in the state to increase from one to 12
over the previous year. This claim has been cited in a number of later
sources, although these added no further supporting evidence.
During
the 1950s, the United States conducted a series of field tests using
entomological weapons (EW). Operation Big Itch, in 1954, was designed to
test munitions loaded with uninfected fleas (Xenopsylla cheopis). In
May 1955 over 300,000 uninfected mosquitoes (Aedes aegypti) were dropped
over parts of the U.S. state of Georgia to determine if the air-dropped
mosquitoes could survive to take meals from humans. The mosquito tests
were known as Operation Big Buzz. The U.S. engaged in at least two other
EW testing programs, Operation Drop Kick and Operation May Day.
1960s
In
1963, 22 elderly patients at the Jewish Chronic Disease Hospital in
Brooklyn, New York City were injected with live cancer cells by Chester
M. Southam, who in 1952 had done the same to prisoners at the Ohio State
Prison, to "discover the secret of how healthy bodies fight the
invasion of malignant cells". The administration of the hospital
attempted to cover the study up, but the New York medical licensing
board ultimately placed Southam on probation for one year. Two years
later, the American Cancer Society elected him as their vice
president.
From 1963 to 1969, as part of Project Shipboard
Hazard and Defense (SHAD), the U.S. Army performed tests which involved
spraying several U.S. ships with various biological and chemical warfare
agents, while thousands of U.S. military personnel were aboard the
ships. The personnel were not notified of the tests, and were not given
any protective clothing. Chemicals tested on the U.S. military personnel
included the nerve gases VX and Sarin, toxic chemicals such as zinc
cadmium sulfide and sulfur dioxide, and a variety of biological
agents.
In 1966, the U.S. Army released Bacillus globigii
into the tunnels of the New York City Subway system, as part of a field
experiment called A Study of the Vulnerability of Subway Passengers in
New York City to Covert Attack with Biological
Agents. The Chicago subway system was also subject
to a similar experiment by the Army.

Avoid contact with contaminated water and surrounding areas
August 30, 2023
Naples, Fla. – The Florida Department of Health in Collier County (DOH-Collier) is advising the public not to enter the water due to the possible increased risk of waterborne illness. Water quality has been affected by Hurricane Idalia. Swimming is not recommended.
Public Beaches
Heavy winds and rain can negatively impact coastal waters. Excessive amounts of rain and storm surge can increase the levels of harmful bacteria in these waters. The sources of the bacteria can vary and include failing septic systems, sewer line breaks, overflowing manholes, and wildlife.
Storm surge and floodwaters may have also brought debris on to the beaches. This debris is hazardous and has also been subjected to harmful bacteria. Under no circumstance should any person handle debris who is not wearing proper safety equipment.
Residents and visitors should avoid swimming in coastal waters until bacterial testing indicates sample results within the state and Environmental Protection Agency’s (EPA) standards. Testing will begin as soon as conditions are safe, and areas are accessible. Test results can be accessed at the Florida Department of Health Healthy Beaches website: https://www.floridahealth.gov/environmental-health/beach-waterquality/index.html.

Santa Rosa County's water is at risk. Growing area while protecting wellfield no easy task
2022
With Santa Rosa County experiencing exponential growth in the East Milton area, outgoing County Commissioner Bob Cole convened a workshop last week to discuss ways to protect the wellfield that supplies the county's water.
The East Milton Area Wellfield Protection District was established between 2010 and 2013 to protect an area bounded on the south by U.S. 90 and the west by State Road 87. The Fairpoint Regional Utility System and East Milton Water System operate approximately 12 wells within the area from which they draw water from the Sand and Gravel Aquifer.
At present, the wells supply water to more than 85,000 residents.
"This is a very vulnerable aquifer," Gary Eichler, an expert hydrogeologist speaking for Fairpoint Regional, warned commissioners. The aquifer, which is fed by rainwater, is "highly susceptible to contamination from above."
The Santa Rosa County Commission is considering a proposal to allow a new borrow pit inside its East Milton Wellfield protection area

Deadly fungus detected in Florida, spreading rapidly, CDC warns
Mar 21, 2023
(NEXSTAR) – A fungus that poses “an urgent antimicrobial resistance threat,” according to the Centers for Disease Control and Prevention, has already been detected in more than half of U.S. states.
Candida auris, or C. auris, is so concerning because it is often resistant to anti-fungal drugs, making it hard to treat infections. It can also be hard to identify with standard lab tests, making it even more difficult to treat properly and early.
The fungus was first detected in the United States in 2016. The fungus “spread at an alarming rate” between 2020 and 2021 in health care facilities, the CDC wrote in a memo released Monday, and has continued to spread in 2022.

Study Finds Pensacola Has The Nation’s Worst Water
December 13, 2009
Pensacola has the worst drinking water of any American city, according to the results of a national survey released Saturday.
In the study, there were 21 chemicals found in Pensacola’s water that exceeded health guidelines, including radium, lead, bezene and carbon tetracholride.
In an unprecedented analysis of 20 million tap water quality tests performed by water utilities between 2004 and 2009, Environmental Working Group (EWG) found that water suppliers detected a total of 316 contaminants in water delivered to the public. The Environmental Protection Agency (EPA) has set enforceable standards for only 114 of these pollutants.
Another 202 chemicals with no mandatory safety standards were found in water supplied to approximately 132 million people in 9,454 communities across the country. These “unregulated” chemicals include the toxic rocket fuel component perchlorate, the industrial solvent acetone, the weed killer metolachlor, the refrigerant Freon and radon, a highly radioactive gas.
Pensacola’s worst water ranking was among 100 of the nation’s largest water systems in cities over 250,000 in population. In North Escambia, water systems are operated by small independent water companies such as Walnut Hill Water Works, Molino Utilities, Central Water Works, Bratt-Davisville Water System and the Town of Century. These smaller water systems were not part of the worst water results. Only the water provided by the Emerald Coast Utilities Authority (ECUA) in the Pensacola metro area was part of the water study. The smaller North Escambia water systems were not included in the study by EWG.

Widespread human waste pollution in surface waters observed throughout the urbanized, coastal communities of Lee County, Florida, USA
2023
Abstract
The coastal communities of Lee County, Florida, USA have grown rapidly since the 1970s. In this county, drainage ditches, canals, creeks, and the Caloosahatchee River Estuary often have high concentrations of nutrients and bacteria limiting their designated uses. Septic systems have previously been identified as a major pollution source in some areas of Lee County; therefore, this study sought to identify the extent of this issue throughout the county. To accomplish this, surface water samples were collected at 25 ditch, creek, or canal sites suspected of human waste contamination from septic systems in various drainage basins throughout Lee County during January 2020–January 2021. Water samples were analyzed for nutrients, dual stable nitrate isotopes (δ15N-NO3−, δ18O-NO3−), fecal indicator bacteria (enterococci, Escherichia coli), a molecular tracer of human waste (HF183), and chemical tracers of human waste (the artificial sweetener sucralose, pharmaceuticals). Particulate organic matter (POM) and macrophytes were also collected and analyzed for stable carbon (δ13C) and nitrogen (δ15N) isotopes, as well as elemental composition (C:N:P). To broaden the assessment of stable isotope values and C:N:P, archived macrophyte samples from 2019 were also included in analyses. Ammonium concentrations were high (> 4.3 μM) in 55 % of samples. Fecal bacteria were high in 66 % of samples. HF183 was detected in 50 % of samples and positively correlated with enterococci (r = 0.32). Sucralose concentrations were high (> 380 ng/L) in 54 % of samples, while carbamazepine was detected in 40 % of samples. Human waste N sources were indicated by δ15N > 3.00 ‰ at 44 % of sites by δ15N-NO3−, 68 % of sites by POM, and at 100 % of sites where macrophyte samples were collected. This large-scale study provides evidence of widespread human waste pollution throughout Lee County and can help guide infrastructure improvements to promote sustainable development. These findings should be applicable to urbanized regions globally that are experiencing declines in water quality and harmful algal blooms due to development with inadequate infrastructure.

USGS Finds 28 Types of Cyanobacteria in Florida Algal Bloom
May 31, 2017
A new U.S. Geological Survey study that looked at the extensive harmful algal bloom that plagued Florida last year found far more types of cyanobacteria present than previously known.
This microscope image shows Dolichospermum circinale, which was one of
the 28 species of cyanobacteria USGS scientists discovered during the
major harmful algal bloom that hit southern Florida last year. Many
varieties of the cyanobacteria found in the bloom are capable of
creating harmful toxins. This species is capable of creating saxition,
which is the second most potent natural toxin in the world. Photo by

Exposure to microcystin among coastal residents during a cyanobacteria bloom in Florida
2020 Feb 5
Abstract
Florida has experienced multiple cyanobacteria blooms in recent years
the most severe of which occurred in 2016 and 2018. Several toxins are
produced by proliferating cyanobacteria, including the hepatotoxin
microcystin (MC). Harmful algal blooms (HABs) caused by cyanobacteria
have the potential to impact public health. However, to date there have
been limited attempts to quantify exposure in human populations. This
study investigated potential exposure to the cyanobacterial toxin, MC by
measuring concentrations in swabs of the nasal mucosa. In addition, the
relationships between nasal concentrations of MC, environmental
concentrations and activity patterns were assessed. Participants (n =
125) were recruited in 2018 during a cyanobacterial bloom of Microcystis
aeruginosa and completed a questionnaire which included location, type,
and duration of recreational or occupational contact with impacted
waterways within the last 10 days. Water samples were collected
concurrently. A sterile swab was used to collect a sample from the nasal
mucosa. Concentrations of MC were measured by ELISA. Of the 121
participants who provided nasal swabs, 115 (95.0 %) had concentrations
of MC above the limit of detection with a mean concentration of 0.61 +
0.75 ppb. There were significant differences (p < 0.01) in mean MC
concentration between individuals with direct contact with impacted
waters (0.77 + 0.88 ppb) compared to those with no recent contact (0.37 +
0.49 ppb). Higher concentrations were observed among occupationally
exposed individuals. Nasal concentrations of MC varied significantly
over time and location of exposure to the bloom, concordant with
concentrations in water samples. The results suggest that inhalation of
aerosols may be an important pathway for exposure to MC. Nasal MC
concentrations were generally highest during periods when concentrations
in the surrounding waters peaked. Further research is needed to
characterize the public health implications of exposure to
cyanobacterial blooms.

Grundfos KPL Stormwater Pumps Play Instrumental Role in Florida Everglades Restoration Project
February 26, 2024
Grundfos Pumps Help Move Water From Lake Okeechobee to the Everglades Agricultural Area Stormwater Treatment Area For Cleaning, Storage; Project to Provide Clean Water to the Everglades, Coastal Communities, Aquifers
BROOKSHIRE, Texas–(BUSINESS WIRE)–#Grundfos—Grundfos, a global leader in water technology and services, announced today that the Grundfos KPL submersible axial flow propeller pumps are installed in multiple pump stations in the Everglades Agricultural Area (EAA) Stormwater Treatment Area. With the ability to pump 146,000 gallons of water per minute, Grundfos KPL pumps will move water from Lake Okeechobee into the 6,500-acre EAA stormwater treatment area and reservoir for storage and cleaning. The clean water will then move south to nourish the Everglades and replenish Florida’s aquifers and the Florida Bay.
“The EAA Reservoir and Stormwater Treatment Area is a triumph in sustainable design that will positively impact Florida’s residents, the local economy and the native wildlife for generations,” said Jack Canfield, Market Development Manager of Water Utilities at Grundfos. “Grundfos’ role in this project exemplifies the company’s belief that everyone deserves access to clean, safe water, including the local ecosystem of birds, fish and plants. We are proud to work with the South Florida Water Management District, the engineers at Brown and Caldwell, and the construction team at Phillips & Jordan to ensure the success of a hydrological restoration project of this scale and complexity.”
For decades, toxic runoff from agricultural land use entered Florida’s canal system and made its way into natural waterways, lakes and coastal communities. In 2019, Florida Governor Ron DeSantis enacted an ambitious Everglades restoration project that includes the EAA Reservoir and Stormwater Treatment Area, which will use the natural filtration systems of the Everglades to reduce harmful discharges like green algae and other bacteria and restore the natural flow of clean water to South Florida.
Grundfos KPL submersible axial flow propeller pumps are installed at two pump stations within the stormwater treatment area. One pump station is now operational, and the other is completing the testing and analysis phase while power is connected to the station.
“The entire Grundfos team feels immense pride as we see this critical phase of the Everglades restoration project come to fruition,” said HP Nanda, EVP & Divisional CEO of Water Utility at Grundfos. “As stewards of our environment and a global leader in water solutions, we recognize the critical role water plays in sustaining life and ecosystems. The installation of these Grundfos solutions marks a significant step forward in our commitment respect, protect and advance the flow of water. Through innovative technology and collaborative efforts, we aim to ensure a brighter, healthier future for generations to come.”

- In 2016, harmful algal blooms drove away half of would-be Florida tourists, according to a Black Hills State University and University of Florida’s Tourism Crisis Management Initiative study.
- That summer and this summer, the governor declared a state of emergency for several counties, including Lee.
- Harmful algal blooms are estimated to cost the United States at least $50 million a year, with public health at about $20 million or about 42 percent of the bill, according to the Woods Hole Oceanographic Institution.
- A 2015 Florida Realtors report concluded pollution in the
Caloosahatchee and St. Lucie river systems negatively impacted home
values after examining sales and water data from 2010 through 2013.

Bioluminescent Bacteria Combat Pollution in Fragile Florida Ecosystem
12/20/2011
Bioluminescence is an ability shared by creatures around the planet that allows them to generate light – in fact, 90% of life in the world’s oceans possess this characteristic. Whereas most animals use it to help them find food, attract mates, and defend against predators, a marine biologist is harnessing bioluminescent bacteria to save one of Florida’s most precious and threatened ecosystems – the Indian River Lagoon. By mixing bioluminescent bacteria with sediment from the 156-mile estuary, renowned scientist Dr. Edith Widder is able to determine how many toxic chemicals are present in the water.

Cumene Contamination in Groundwater: Observed Concentrations, Evaluation of Remediation by Sulfate Enhanced Bioremediation (SEB), and Public Health Issues
2020
Abstract
Isopropylbenzene (cumene) is commonly encountered in groundwater at petroleum release sites due to its natural occurrence in crude oil and historical use as a fuel additive. The cumene concentrations detected at these sites often exceed regulatory guidelines or standards for states with stringent groundwater regulations. Recent laboratory analytical data collected at historical petroleum underground storage tank (UST) release sites have revealed that cumene persists at concentrations exceeding the default cleanup criterion, while other common petroleum constituents are below detection limits or low enough to allow natural attenuation as a remediation strategy. This effectively makes cumene the driver for active remediation at some sites. An insignificant amount of research has been conducted for the in-situ remediation of cumene. Sulfate Enhanced Biodegradation (SEB) is evaluated in a field case study. The results from the field case study show an approximate 92% decrease in plume area following three rounds of SEB injections. An additional objective of this research was to determine the cumene concentration in fuels currently being used to determine future impacts. A review of safety data sheets from several fuel suppliers revealed that cumene concentrations in gasoline are reported typically as wide ranges due to the proprietary formulations. Several fuels from different suppliers were analyzed to determine a baseline of cumene concentration in modern fuels. The results of the analysis indicated that cumene accounts for approximately 0.01% (diesel) to 0.13% (premium gasoline) of the overall fuel composition. Cumene generally is considered to be of low human health toxicity, with the principal concern being eye, skin, and respiratory irritation following inhalation of vapors in an occupational setting, but it has been regulated in Florida at very low concentrations based on organoleptic considerations.

Seriousness of the water shortage in Cape Coral

Concerns over the water levels in Southwest Florida are growing to some, but others are shrugging the information off.
Parts of both Cape Coral and unincorporated Lee County are under mandatory water restrictions due to the low levels of drinking water.
It’s becoming a concern to some because it means their well, which is the source of their home’s water, is at risk of drying up. While some aren’t too worried because they say Cape Coral always runs dry, others remember what it’s like to be without water.

Study: North Cape Coral slowly sinking, likely due to over-pumping for city's water desalinization plant
2023
Nearly 40 square miles of North Cape Coral is sinking, an inch or more every year, due to over-pumping the aquifers below the city for household water.
The reason for a deepening depression in that area was detailed in a recent study in the journal Science of Remote Sensing by researchers from the Geological Survey of Norway.
At the center of the sinking soil is Cape Coral’s desalinization plant and the 22 wells scattered through the surrounding neighborhoods. Pumping brackish water from as deep as 1,250 feet into the reverse osmosis plant,the wells produce more than one million gallons of clean, drinkable water every day for the city’s burgeoning population.
But that rate of extraction comes with serious environmental costs that far exceed the price paid in dollars to run the desalinization plant, the researchers say.
The heavy pumping lowers the water table by more than three feet of water per year, and without giving the aquifers time to refill, so much underground space that held water has collapsed it could house enough water to fill eight Empire State Buildings.
Now that the aquifer has compacted it can never refill. The landscape above is sinking into the void, which has dropped the ground level surrounding the desalinization plant by as much as 1.5 feet in a process called subsidence, the Norwegian researchers report.
The oblong-shaped depression is poised to wreak havoc on anything built on the land surrounding the water plant, which includes hundreds of homes, several high schools, two middle schools, two parks, two sports complexes, and a hospital.
“Groundwater pumping for feeding the … desalination facilities is the primary factor responsible for land subsidence in the northern part of the city,” the study's authors wrote. “Such deformation likely results from overusing the aquifer system. That aggressive groundwater pumping might potentially facilitate natural sinkhole formation.”
No scientific agreement
Rachael Rotz, a hydrogeologist at The Water School at the Florida Gulf Coast University, was not involved in the study, but said the subsidence around the northern wellfield could be a mere coincidence. The real culprit, she said, could be growth...

Acid Precipitation and Sulfate Deposition in Florida
30 May 1980
Abstract
The acidity of rainfall in Florida has increased markedly in the past 25
years, and the average sulfate and nitrate concentrations have
increased by factors of 1.6 and 4.5, respectively, over the period.
Annual average pH values below 4.7 now occur over the northern three quarters of the state. Summer rainfall has average pH
values 0.2 to 0.3 unit lower than winter rainfall, and sulfate
concentrations at most sites are higher in summer. The annual deposition
of H+ (about 300 to 500 equivalents per hectare) in northern
Florida is a third to a half of the deposition in the heavily impacted
northeastern United States; comparable figures for excess sulfate
(derived from sulfur dioxide) are 7 to 11 kilograms of sulfur per
hectare or 50 to 90 percent of the sulfate deposition rates at Hubbard
Brook, New Hampshire.

Impacts of Sulfate Contamination on the Florida Everglades Ecosystem
2004
Water quality is a key issue facing the restoration of the Florida Everglades. For example, agriculturally derived phosphorus entering the Everglades has caused eutrophication of 6 to 10 percent of the ecosystem, resulting in changes in the native plant communities. Phosphorus contamination remains an important issue facing Everglades restoration, but recent work by the U.S. Geological Survey (USGS) has pointed to other water-quality issues critical to the overall health of the Everglades ecosystem.
Among the most important of these other water-quality issues in the Everglades is sulfate (SO42-) contamination. Sulfate contamination affects as much as one-third of the freshwater Everglades, and sulfate concentrations are 60 to 100 times historical levels in heavily affected areas. The effects of sulfate contamination on ecosystem health have not been fully studied, but links between sulfate contamination and high levels of methylmercury in the ecosystem have been documented. Also, sulfate contamination may be contributing to declines in native plants by altering chemical conditions in the sediments. Ongoing USGS research will further delineate these effects and explore possible options for mitigating sulfate contamination in this unique ecosystem.

Radiation levels in Lakeland homes again in question

Did the state use the wrong radiation detectors?
LAKELAND, Fla. (WFLA)- In Florida, phosphate mining is lucrative and controversial.
It tears up the earth, bringing radioactive minerals buried beneath to the surface.
Thousands of people live in homes in Lakeland’s Grasslands and Oakbridge communities, on what was once the Poseidon mine.
A lawsuit filed in 2017, claims the Drummond Company, which owned the mine, reclaimed it, then despite high radiation levels, built on it.
“This Gamma radiation affects the way cells change. And when you affect the way cells change, it causes cancer,” attorney Mark Lanier pointed out.
Lanier heads up the law firm suing Drummond.

Radionuclide Contamination
https://floridadep.gov/water/source-drinking-water/content/radionuclide-contamination
Sources
There are two sources of radioactive contamination in drinking water. The first is naturally occurring radionuclides contained in the soil that water moves through. Some areas in Florida are susceptible to contamination from phosphate-rich soils and rock.
The second source of radioactive contamination comes from man-made sources. There is no known man-made contamination of drinking water in Florida.
Radionuclides found in drinking water are members of three radioactive series - uranium, thorium and actinium - and include the naturally occurring elements radium, uranium and the radioactive gas radon. These contaminants may cause different types of biological damage. Radium concentrates in the bones and can cause cancers. Uranium can cause cancers in the bones and can have a toxic effect on kidneys.
The standards and rules governing radionuclides is currently under revision by the U.S. Environmental Protection Agency. Florida will adopt the new standards and rules when issued by EPA.

Imminent Failure of Phosphogypsum Stack in Tampa Bay Exposes Phosphate Industry Risks
2021
Catastrophic Wastewater Release Highlights Need for Federal Action
ST. PETERSBURG, Fla.— Manatee County officials have issued evacuation orders for the area surrounding Florida’s Piney Point in anticipation of the imminent catastrophic collapse of a phosphogypsum stack retention pond holding up to 700 million gallons of wastewater.
It has been reported that 22,000 gallons a minute are being discharged from the holding pond to prevent the release of millions of gallons of wastewater and a failure of the radioactive phosphogypsum stack itself. Phosphogypsum is the radioactive waste from processing phosphate ore into phosphoric acid, which is predominantly used in fertilizer.

215 Million Gallons of Radioactive Water Threaten Drinking Water in Florida
2021
Mulberry, Florida is now home to a giant sinkhole that has caused 215 million gallons of radioactive water to leak into the state’s supply of drinking water.
The contamination occurred when a sinkhole appeared at a phosphate fertilizer plant near Tampa, which damaged the stack where waste water was stored. This filtered into the state’s aquifer system, which supplies water to residents, making the water contain phosphogypsum. Phosphogypsum is classified as slightly radioactive and is a byproduct of the creation of fertilizer. This is due to the naturally-occurring uranium and radium in the phosphate ore.

Salt levels in Florida’s groundwater rising at alarming rates; nuke plant is one cause
2020
Louis Fernandez walks along a flooded street in Miami Beach, Fla., during high tides caused by the lunar cycle Sept. 30, 2015. South Florida is under siege from invading saltwater above and below ground as seas rise due to climate change.
Deep beneath the Homestead-Miami Speedway, home of NASCAR’s Dixie Vodka 400, saltwater carries on a slower but more consequential race into the drinking-water supply of 3 million people in South Florida.
In 1999, the U.S. Geological Survey installed one of its first monitoring wells there using an electromagnetic technique to measure the thickness of intruding saltwater into the Biscayne aquifer. The racetrack is situated 5 miles from the Atlantic Ocean.
By 2018, a saltwater wedge at the bottom of the aquifer had expanded to a thickness of 20 feet. By last year, the chloride concentration had increased more than tenfold, to 12,000 milligrams per liter. The chloride concentration of seawater is about 35,000 milligrams per liter.
South Florida’s flooding streets get the attention, but what is happening beneath the surface presents clear — and in some cases eye-popping — evidence of another threat: saltwater intrusion.
Analysis of chloride testing in South Florida by the Howard Center for Investigative Journalism at the University of Maryland shows dozens of instances where the point at which saltwater meets freshwater — known as the interface — is moving inland.
U.S. Geological Survey testing shows saltwater has continued to migrate into South Florida’s aquifer system. Nearly one-third of 215 monitoring wells showed a five-year trend of increasing salinity with just 16 showing a downward salinity trend. (Test results at many other wells also showed increasing chloride levels, but those were not viewed by government hydrologists as a significant trend.)
The Geological Survey began special monitoring in Florida in the 1940s when wells too salty for drinking became common. Records since reflect a relentless salting of South Florida, a threat both to drinking water and to the environment.
Federal and state agencies have been monitoring sea-level rise for decades. Yet the Nuclear Regulatory Commission did not consider the impact of rising seas and increasing salt before granting a first-ever, 80-year license in December for the Turkey Point nuclear plant on Biscayne Bay. The plant is cooled by a series of canals that spewed millions of gallons of heavily saline water into the aquifer beneath it.
In a case playing out in the U.S. Court of Appeals for the District of Columbia challenging the relicensing, environmental advocates contend the NRC didn’t adequately consider the plant’s pollution and future impacts of climate change.
Above ground, more extreme storm surges and high tides also deliver salt, sometimes far inland. By 2050, destructive high tides could plague the southeast Atlantic by anywhere from 25 to 85 days a year, the National Oceanic and Atmospheric Administration predicts.
In July, the Southeast Florida Regional Climate Change Compact projected that by 2040, seas would rise between 10 to 17 inches over 2000 levels, based on predictions from NOAA and the Intergovernmental Panel on Climate Change, the United Nations body that has studied the issue since the 1980s.
Harold Wanless, a University of Miami geographer known for sobering but accurate predictions about the changing climate, said the Atlantic Ocean in South Florida already is a foot higher than in 1930 and noted that saltwater advances inland from both the east and southwest.
“There’s major saltwater intrusion that is further diminishing our freshwater resources. And we’re probably going to lose most of (the freshwater resources) with another 2 feet of sea-level rise,” he said.
Wanless’ research at Cape Sable at the bottom of the Florida Everglades 15 years ago documented the environmental changes spreading across sensitive lands. His report to the U.S. Department of the Interior described Cape Sable as the canary in the coal mine, and recommended the government consider the safety of people using the back country there due to threats from widening creeks and higher waters.
Today, the National Park Service says of this once-pristine area: “The interior freshwater marsh has disappeared almost entirely.”
Adds Wanless: “We’ve lost almost all of the sawgrass marsh in Cape Sable because of saltwater intrusion.”
Disrupting a balance
Months after Florida became a state in 1845, the state Senate passed a resolution asking Washington to look into draining the vast, interconnected lands of freshwater that stretched from what is now Orlando to the Florida Keys.
By the start of the 20th Century, Florida politicians and their backers proceeded with fervor to reclaim the wild lands. Canals emptied Everglades water to pave the way for farming and development, part of the storied Florida land boom. The effects of upsetting the balance between freshwater and saltwater in low-lying Florida became apparent within decades as Miami-area wells grew too salty for use.
By 1940, the Geological Survey was monitoring dozens of wells to gauge saltwater movement. Government hydrologists concluded saltwater had already traveled miles into the Biscayne aquifer.
The Geological Survey has more than 100 monitoring wells from Jupiter to near the bottom of the Florida mainland, most of them 2-inch-wide PVC pipes that reach to the bottom of aquifers. Government hydrologists attempt to place the wells ahead of the saltwater to measure its pathways and speed as an aid to planners.
The movement can be dramatic, according to results examined by the Howard Center. A well in south Miami showed a modest chloride level of 24 milligrams per liter more than a half-century ago. The latest reading, in September, showed 5,650 milligrams per liter.
Last December, a Geological Survey well in southwest Miami along the Blackwater Canal suddenly showed a spike in chloride, to 600 milligrams per liter. The reading caught the eye of hydrologists because it showed how canals are enabling saltwater to flow farther inland even as it travels underground.
Scott Prinos, a hydrologist in the Geological Survey’s Caribbean-Florida Water Science Center, said most of the wells east of the saltwater front show the front continuing to move inland.
In July 2018, a newly installed well measured chloride at 302 milligrams per liter. In May, 22 months later, that saltiness had spiked to 2,100 milligrams per liter. In September, the chloride content was even greater — 2,310, well testing shows.
The well is situated 5 miles west of Florida Power & Light’s Turkey Point Nuclear Generating Station, where operations are proving to be yet another problem in South Florida’s quest to stave off a saltwater invasion.
Trouble at Turkey Point
A grand jury convened by the Miami-Dade County state’s attorney last year on the health of Biscayne raised alarms about saltwater intrusion driven by the plant. In Miami, grand juries venture beyond criminal matters into issues of public importance.
A massive plume of saltwater released by the plant’s unique method of cooling two nuclear reactors “constitutes a serious threat to the source of our freshwater,” the grand jury reported.
The nuclear plant has spewed millions of gallons of water, some of it saltier than the ocean, into the Biscayne aquifer and surrounding environment.

Decades later, EPA still working on cleanup of Florida’s “Mount Dioxin”
2022
Pensacola wood treatment plant just one of 92 Superfund sites around the Sunshine State
(Creosote and “critical race theory”)
From 1942 to 1982, the Escambia Wood Treatment Company produced power poles, railroad ties, pilings and other wood products coated with creosote and PCBs to make them last. Although it was an industrial operation, the factory was in the middle of the city and surrounded by homes.
“A lot of the homes around there belonged to people who worked there,” explained Chips Kirschenfeld, the natural resource department manager for Escambia County, which now owns the site.
The residents had little choice when it came to buying homes there, explained Frances Dunham, who was a community activist at the time. That area was one of the few neighborhoods in the ‘50s and ‘60s where banks would lend money to Black people to buy houses, she explained.
If you are still wondering what “critical race theory” might be, here’s a good example. It shows how it’s not a theory but a fact.
The Black families who lived in that neighborhood felt hemmed in by factories and the railroad track. Pensacola is one of the Sunshine State’s rainiest cities, and during storms, toxic stuff from the Escambia Treatment site would wash over into people’s yards.
Escambia Treatment was no fly-by-night outfit, either. One of the owners happened to be Pensacola’s mayor from 1967 to 1971. But political influence is no guarantee of corporate responsibility – quite the opposite, in fact.
All the managers were white and all the workers Black. The employees knew they were being exposed to harmful chemicals that sometimes ate away their shoes in a matter of weeks, but their choices were limited. One later told an NPR reporter: “It was horrible for us all, but we all had to try to make a living.”
After Congress passed the Clean Water Act and other environmental regulations in the 1970s, the company’s owners saw the writing on the wall. They filed for bankruptcy and abandoned the plant.
They left behind what Dunham described as “leaking drums, a lab full of broken equipment and open containers, an overturned electrical transformer, crumbling asbestos insulation around a boiler” – and something worse in the soil and water.
The owners had stored the site’s toxic waste – not just creosote and PCB’s, but also polycyclic aromatic hydrocarbons and dioxins – in unlined pits on the site. Essentially, the workers had been ordered to pour the toxic waste into a hole in the ground. As often happens with holes in porous Florida, what was put in didn’t stay there.
A few years later, during an investigation of a Superfund site next door – yes, Pensacola has two Superfund sites adjacent to each other, the second one being a phosphate processing facility – regulators made an alarming discovery. The Escambia Wood site was full of contaminants too.
At first the EPA did not declare this a Superfund site. Instead, it was classified as a site in need of emergency cleanup, not unlike the Exxon Valdez oil spill.
That meant send workers to rush in right away, instead of holding meetings with the neighbors to inform them about what was happening. When former employees offered to point out areas of extreme contamination, Dunham said, one of the EPA coordinators – who called himself a “cowboy” — told them to get lost.
Instead, the EPA had crews in special contamination suits start digging up the soil, the sludge and everything else. They planned to incinerate it, but at first they were just piling it up. Before long, they had excavated 250,000 cubic yards of toxic soil, creating what locals dubbed “Mount Dioxin.”

AIR FORCE ADMITS AGENT ORANGE SPRAYING IN FLORIDA IN 1962-70
2009
In the 1960s, Ernie Rivers taught Navy flight
students at the Pensacola Naval Air Station
how to live off the land if their plane was
downed. He was the officer in charge of the
survival unit, overseeing 30 to 35
instructors, who taught more than 100 men
a week how to survive with only a compass,
map, and a hunting knife. Every week
groups of students would camp for three
days, using different sites on Eglin Air
Force Base Reservation in Florida.
When the winds and clouds were right, Rivers and his men would watch
planes pass overhead, clouds of spray coming from them. Several times he
and his men were sprayed. “I’d say, ‘At least we don’t have to use bug
repellant,’” he noted, laughing, during an interview. That was a big plus,
they thought, for them as well as Army Rangers who were also training out
in the bayous of the Florida panhandle, where mosquitoes and other bugs
could make life miserable.
Rivers and the students thought they were watching the Air Force spray
DDT to kill mosquitoes. What was actually being sprayed, he said, was
Agent Orange. Documents show that gallons of the defoliants Agent
Orange, Agent Purple, and Agent White were sprayed at Eglin. In fact,
according to officials overseeing the program, the Air Force sprayed a test
area on the base with more dioxin than any similar area in Vietnam. The
fact that Agent Orange was sprayed in Florida for eight years was not
widely known then or even today. Only in the last several years has the
documentation on the spraying been made publicly available by Alvin
Young, an Air Force scientist for more than 15 years at Eglin. Young
oversaw a huge research project evaluating how massive spraying of
Agent Orange at the Florida air force base affected its soil, water, plants,
fish, and animals.
In Vietnam during the war, a typical mission disseminated 14.8 kg of Agent
Orange per hectare, according to Young. Most of the Agent Orange in
Vietnam was intercepted by forest canopy, and some of it was destroyed
by the sunlight. But at Eglin, where the spray rate was 876 kg per hectare,
the trees and bushes already had been removed from the spray area.
Young recently wrote that each hectare at Eglin received at least 1,300
times more dioxin than a hectare sprayed in Vietnam. The spraying went on
from 1962 to 1970. The test area was three kilometers square.
Eglin was one of several key military installations involved with Operation
Ranch Hand and posters plastering its buildings made that clear. Pictures
of Smokey the Bear, the unofficial Operation Ranch Hand mascot,
proclaimed, “Only you can prevent a forest.” Eglin had responsibility for
training the aircrews, fitting aircraft with spray equipment, and testing the
spray systems and spray patterns.
Spray systems were tested in an area divided into four grids. From June
1962 through June 1970 fixed-wing airplanes, helicopters or jet aircraft
sprayed massive amounts of defoliants on the area. During that time 75,000
liters of Agent Orange, 61,200 liters of Agent Purple, 15,800 liters of Agent
White, and 16,600 liters of Agent Blue rained onto the base.
There were 155,000 kg sprayed of the active ingredients in the herbicides.
The Air Force estimated that the amount of dioxin sprayed was between 5.6
and eight pounds, an enormous amount since it is one of the more toxic
chemicals, even in minute amounts. Because of its toxicity, dioxin is
generally measured in parts per trillion.
In the late 1960s, Air Force officials became concerned about the
ramifications of spraying dioxin in massive amounts stateside. “After
repetitive applications, personnel involved with the test program expressed
concern about potential ecological and environmental hazards that might
be associated with continuance of these test programs,” Young wrote later
in an Air Force technical report.
Officials overseeing the test program knew how toxic Agent Orange was
but seemed unconcerned, so long as it was used in Vietnam. James Clary,
who worked at Eglin and helped design the spray system for herbicides,
wrote in a 1988 letter to then-Sen. Tom Daschle: “When we [military
scientists] initiated the herbicide program in the 1960s, we were aware of
the potential for damage due to dioxin contamination in the herbicide. We
were even aware that the ‘military’ formulation had a higher dioxin
concentration than the ‘civilian’ version due to the lower cost and speed of
manufacture. However, because the material was to be used on the
‘enemy,’ none of us were overly concerned.”
But when it started to be sprayed in enormous quantities on an American
base, some Air Force officials became concerned and wanted to study the
impact of the spraying. Their concern doesn’t seem to have been motivated
only by worry about ecological and public health issues...

Paradise Squandered: Legacy of pollution haunts Escambia County
2019
Despite Escambia County's outward beauty, our community has long been plagued by pervasive pollution from industrial plants, landfills, septic tanks and the like.
Pollution was so bad that in 1999, a special grand jury was convened to assess local air and water quality. The jury found that local regulators were falling down on the job, that local elected officials were serving corporations rather than citizens, and that we needed to take immediate action to stem the tide of toxins in our community.
The grand jury issued an array of recommendations to improve pollution control, environmental monitoring, government accountability and other issues, but 20 years later, we're still seeing a lot of the same old problems.

Escambia County ranks among top places for toxic releases in the country
2017
ESCAMBIA COUNTY, Fla. (WEAR) — Escambia County is near the top of the list when it comes to counties in the country with the highest release of toxins into the environment. Forbes used data from the Environmental Protection Agency and found Escambia County was the 11th largest producer of toxins out of the country's nearly 3,000 counties.
"It's varied between 10 and 13th over the past 16 years in its ranking," said Dr. John Lanza, director of the Florida Health Department.
Every year the EPA puts out a Toxics Release Inventory (TRI) report. It compiles data reported by industries across the country. In 2016, industries in Escambia County reported releasing 34 million pounds of toxins either into the air, water, or ground.
Ascend Performance Materials in Cantonment was responsible for 32 million pounds of it. According to Ascend, the Cantonment facility uses deep wells to send processed wastewater into the ground into what is known as the Lower Floridian Aquifer. Lanza said it is injected so far down, it does not affect our drinking water supply.
"For our foreseeable future there's no public health threat, no threat health to the citizens of Escambia or surrounding areas because it's down 1,600 feet," Lanza said.
Ascend reports the facility only injects treated, non-hazardous wastewater into the deep wells and only one percent accounts for either nitrate or organic compounds. The company said they have not had any issues during the 54 years the wells have been in operation.
Lanza said if the deep wells were factored out of the TRI report, it would drop Escambia County's ranking to 254. International Paper Pensacola Mill was the second largest contributor to toxic releases in the county with nearly 1.5 million pounds reported. Gulf Power was third and released just over 260,000 pounds of toxic materials.
"We have always encouraged all the industries in Escambia County to try to reduce the amount of waste that they had over the years and to the greatest extent, they've done that because the numbers have significantly decreased other than the deep well injection," Lanza explained.
Lanza said the TRI list does not show the full picture of environmental issues. He pointed out Superfund sites are not included in the data, nor are airports and interstates which account for pollution into the air.
"We should encourage industry, but also ourselves to limit that pollution as much as we possibly can," Lanza said.

List of Superfund sites in Florida
https://en.wikipedia.org/wiki/List_of_Superfund_sites_in_Florida
This is a list of Superfund sites in Florida designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations. These locations are known as Superfund sites, and are placed on the National Priorities List (NPL).
The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. As of May 3, 2010, there were 52 Superfund sites on the National Priorities List in Florida. Three more sites have been proposed for entry on the list and 23 others have been cleaned up and removed from it. There are also twelve Superfund Alternative sites in the state.

‘Look at the water for evidence.’ Data proves Florida pollution prevention not working
Jan. 5, 2022
It’s a textbook Florida morning at a ranch just north of Lake Okeechobee. Cattle roam. Herons and egrets hunt for food. Clouds mosey across the sky.
But beneath this idyllic scene, a silent byproduct lurks. Phosphorus levels, mostly from fertilizer and cow manure, exceeded the state pollution limit by 19 times.
The problem is not exclusive to this Rio Rancho Corp. farm. Rainfall runoff that flows into Lake O from hundreds of surrounding properties routinely exceeds the limit — without the state imposing any consequences, a TCPalm investigation found.
All 32 drainage basins around the lake with available data exceeded the limit over a five-year average, according to TCPalm’s analysis of “water year” data from May 2016 to April 2021. Rio Rancho was just the worst in the last two years. Even lesser polluters exceeded the limit by over 100%.
The data proves — for the first time — that Florida’s flagship program to reduce water pollution isn’t working. And that pollution is contaminating waterways and sparking toxic algal blooms in the St. Lucie and Caloosahatchee rivers.
“All one has to do is look at the water for the evidence,” said Indian Riverkeeper Mike Conner, who heads a Treasure Coast nonprofit that advocates for clean water. “The impairment of Florida waters is now at an all-time high.”
The Department of Environmental Protection (DEP) oversees the program involving legally enforceable goals and strategies to reduce pollution, called Basin Management Action Plans (BMAPs). There are 38 plans customized to help waterways in their region.
For the Lake O BMAP, the agency set the phosphorus limit at 40 parts per billion two decades ago, but the basins have exceeded that by a median 5.7 times over the five-year average, TCPalm found.
The worst polluter over those five years — 22 times over the limit — was the East Beach Drainage District, on Lake O’s southeast shore, near Pahokee.
State records don’t show that, though. DEP historically touts progress that often doesn’t match reality because it uses models to give credit for pollution-reduction measures — from reservoirs to informational brochures — assuming they produce intended results. DEP’s resulting graphics, used in public presentations, show progress is being made.
The truth is in the data recorded by the South Florida Water Management District (SFWMD) water-quality monitors, which TCPalm analyzed.

Danger lurking in the water of 6 Tampa Bay beaches: Where to avoid and why
Sep 4, 2021
TAMPA,
Fla. (WFLA) — If you’re hoping to go swimming or fishing in
Hillsborough County this Labor Day Weekend, you may want to reconsider
because county health officials say at least six beaches are unsafe to
swim in.
Many are being advised to stay away from beaches like Ben T. Davis because of dangerous bacteria lurking in the water.
The
Florida Department of Health in Hillsborough County said the amount of
Enterococci bacteria is too high, making the water dangerous to swim in.
They said that bacteria is usually found in the intestinal tract of
humans and animals and is an indication of fecal pollution.

Most
antifouling bottom paints contain cupreous oxide which is a neurotoxin.
It constantly leaches into the water around your boat, creating a
plume. When marine life unsuspectingly swims into the plume, they ingest
the toxin, which attacks their nervous system and they die of
convulsions, thus preventing them from attaching to your boat.
Otheuclear neurotoxins used in the past have been banned worldwide
because of their destructive effects on marine life. Of all the copper
compounds, cupreous oxide is the most deadly.

Pleasure Boatyard Soils are Often Highly Contaminated
2014 Feb 23
Abstract
The contamination in pleasure boatyards has been investigated. Measured
concentrations of copper, zinc, lead, mercury, cadmium, tributyltin
(TBT), the 16 most common polycyclic aromatic hydrocarbons (∑16 PAHs),
and the seven most common polychlorinated biphenyls (∑7 PCBs) from
investigations at 34 boatyards along the Swedish coast have been
compiled. The maximum concentrations were 7,700 for Cu, 10,200, for Zn,
40,100 for Pb, 188 for Hg, 18 for Cd, 107 for TBT, 630 for carcinogenic
PAHs, 1,480 for ∑16 PAHs, and 3.8 mg/kg DW for ∑7 PCB; all 10–2,000
higher than the Swedish environmental qualitative guidelines. In
addition, the mean of the median values found at the 34 places shows
that the lower guidance value for sensitive use of land was exceeded for
the ∑7 PCBs, carcinogenic PAHs, TBT, Pb, Hg, and Cu by a factor of 380,
6.8, 3.6, 2.9, 2.2 and 1.7, respectively. The even higher guideline
value for industrial use was exceeded for the ∑7 PCBs and TBT by a
factor of 15 and 1.8, respectively. TBT, PAHs, Pb, Cd, and Hg are
prioritized substances in the European Water Framework Directive and
should be phased out as quickly as possible. Because of the risk of
leakage from boatyards, precautions should be taken. The high
concentrations measured are considered to be dangerous for the
environment and human health and highlight the urgent need for
developing and enforcing pleasure boat maintenance guidelines to
minimize further soil and nearby water contamination.

Eco-friendly paint most effective against fouling on ships and boats
December 12, 2022
Summary:
Emissions from copper-based antifouling paints are a well-known
environmental problem. As much as 40 percent of copper inputs to the
Baltic Sea come from antifouling paints on ships and leisure boats.
According to a new study, this is completely unnecessary. When the
researchers compared copper-based antifouling paint with biocide-free
silicone-based paint, they found that the environmentally friendly
alternative was best at keeping the fouling at bay.

Crisis in Paradise: Examining Florida's Toxic Triangle and Its Impact on the Space Coast
March 11, 2024
BREVARD COUNTY, FL. - Florida's Space Coast may look like a
paradise with its sun-drenched beaches and glistening waters, but a dark
secret lurks beneath the surface. If you dive deep into research,
you'll uncover intriguing parallels to the contamination found in Camp Lejeune, North Carolina.
However, what makes it even more unsettling is the realization that
Brevard County doesn't house just one military base but three: Kennedy
Space Center, Cape Canaveral Space Force Station, and Patrick Space
Force Base.
INDIAN RIVER LAGOON: The Indian River Lagoon,
often mistaken for a river due to its lengthy appearance, is situated
along these bases and is home to a troubling history of pollution. This
expansive body of water is not just any estuary - it is a national
treasure that the Environmental Protection Agency (EPA) committed to
protecting. Back in 1990, this area received special designation to
ensure the preservation of its ecosystems, but sadly, the current state
of affairs tells a different story. Over the years, sewage, chemicals,
and industrial waste have tainted the once pristine waters, robbing the
habitat of its vibrant marine life like seahorses, stingrays, and
manatees.
Decades ago, the waterways were a haven for local fishermen, but now
they bear witness to the profound impact of pollution. The condition has
worsened to the point where locals decided to impose a tax on
themselves in 2016, all hoping to preserve whatever little was left of
the waterways. The problem has become so widespread that even political
leaders incorporate the Indian River Lagoon and its water quality
concerns into their campaign rhetoric.
Over the last few
decades, the seagrass population has drastically decreased, leading to
manatees facing starvation and the declaration of an Unusual Mortality
Event (UME)
in 2021. Pollution has fueled harmful algal blooms, causing a decline
in fisheries, while unchecked development is encroaching on wildlife
habitats. The lagoon's shellfish have been found to have the highest concentration of microplastics in the world.
Studies have shown an uptick in diseases like cancers, lesions, and
tumors in dolphins, turtles, and fish. Parasites have impacted shrimp
and blue crab populations, with scientists sounding the alarm about
potential human health risks. Swimming in waterways with raw sewage
risks contracting Hepatitis A (HAV), urinary tract infections, and flesh-eating bacteria (vibrio vulnificus).
The once vibrant ecosystem of the lagoon has transformed from
crystal-clear waters to murky green, posing a grave threat to its
natural resources and the well-being of communities near them.
DISEASE CLUSTER CONCERNS: Over the years, several investigations have been conducted into disease clusters in Brevard County. These include a high incidence of leukemia cases in children near a Superfund site in Palm Bay, a high rate of Hodgkin's Lymphoma in teens near Patrick military base in South Patrick Shores, ALS among workers at Kennedy Space Center, and a concerning situation of blood cancer and asthma in Port St. John situated between two power plants. These investigations shed light on the health challenges faced by different communities in Brevard County.
PFAS CONTAMINATION: Fast-forward to 2018, and another alarming
discovery was made—PFAS chemicals were detected in groundwater
throughout the county. The levels were particularly concerning at
Patrick Space Force Base, where they reached a staggering 4.3 million
parts per trillion, making it the third-highest concentration in the
entire country.
The impact of PFAS chemicals on human health is
deeply troubling. Extensive epidemiological studies have revealed a
range of adverse effects, including elevated cholesterol levels,
reproductive and developmental issues, and weakened immune systems.
Shockingly, these harmful chemicals have also infiltrated the
bloodstreams of alligators, manatees, and dolphins in the Indian River,
reaching some of the highest recorded levels.
The source of these
hazardous substances can be traced back to firefighting foams, which
were once innocently sprayed on children for playful fun decades ago.
However, the Department of Defense was aware of the dangers associated
with these chemicals as early as the 1970s, yet continued their use.
This negligence has had far-reaching consequences for human and animal
populations, highlighting the urgent need for stricter regulations and
responsible practices to safeguard the ecosystem and human health.
HOW CHEMICALS ARE REGULATED: Polluting industries have a
reputation for advocating for looser regulations on chemicals and
monitoring, and one such example is perchlorate. Back in the 1990s,
scientific research revealed that exposure to perchlorate during
pregnancy could have significant adverse effects on the developing
brains of both fetuses and infants, with lifelong consequences.
Perchlorate contamination is most commonly found at sites involved in
the manufacturing, testing, and disposing ammunition and rocket fuel.
The Department of Defense has been using perchlorate since the 1940s.
The Defense Department and military contractors such as Lockheed Martin
have aggressively blocked regulation on this chemical.
Many
Americans lack knowledge about how chemicals are regulated in the United
States. The Safe Drinking Water Act does not prioritize health-based
standards; the initial standards were established before 1996.
Additionally, industries spend large sums of money lobbying to obstruct and remove regulations on toxic substances.
The powerful chemical industry influences toxic substance laws, while
the EPA faces challenges due to inadequate funding and a lack of
authority to tackle these critical issues.
Pollution has loomed
like a dark cloud over Brevard, impacting numerous young residents with
rare illnesses. The "toxic triangle" highlights the far-reaching
consequences of contaminated water sources and underscores the urgency
of proactive measures.

10 U.S. cities with the worst drinking water
2011
A
surprising number of U.S. cities have drinking water with unhealthy
levels of chemicals and contaminants. If you live in Pensacola, Fla.,
you may want to invest in a water purifier.
1. Pensacola, Fla. (Emerald Coast Water Utility)
Located
on the Florida Panhandle along the Gulf of Mexico, Pensacola is
Florida's westernmost major city. Analysts say it has the worst water
quality in the country. Of the 101 chemicals tested for over five years,
45 were discovered. Of them, 21 were discovered in unhealthy amounts.
The worst of these were radium-228 and -228, trichloroethylene,
tetrachloroethylene, alpha particles, benzine and lead. Pensacola's
water was also found to contain cyanide and chloroform. The combination
of these chemicals makes Pensacola's water supply America's most
unhealthy.
10. Jacksonville, Fla. (JEA)
Located on the
northeast coast of Florida, Jacksonville is the state's largest city.
According to EWG, 23 different toxic chemicals were found in
Jacksonville's water supply. The chemicals most frequently discovered in
high volumes were trihalomethanes, which consist of four different
cleaning byproducts — one of which is chloroform. Many trihalomethanes
are believed to be carcinogenic. Over the five-year testing period,
unsafe levels of trihalomethanes were detected during each of the 32
months of testing, and levels deemed illegal by the EPA were detected in
12 of those months. During at least one testing period, trihalomethane
levels were measured at nearly twice the EPA legal limit. Chemicals like
arsenic and lead were also detected at levels exceeding health
guidelines.

Florida Environment’s Hidden Menace: Toxic Chemical Pollution
1996
An
Associated Press computer analysis of five years of federal TRI records
examined Florida’s top 25 toxic polluters and the state’s toxic hot
spots.
The AP analysis found an encouraging trend: Many of
Florida’s largest polluters reduced their toxic waste releases between
1989 and 1993.
But a third of Florida’s 67 counties saw their
toxic waste totals grow during that five-year period--sometimes
dramatically, the AP analysis showed.
Industrial Polk County in
west-central Florida was the top toxic hot spot with 24.6 million pounds
of toxic waste released in 1993, according to the most recent,
available TRI statistics from the Environmental Protection Agency.
Most
of the toxic waste released in Polk County in 1993 came from companies
that mine phosphate and turn it into fertilizer for farms and gardens.
Polk County had 55.5 pounds of toxic waste per resident.
The
state’s top toxic polluter, IMC-Agrico, has three phosphate plants in
the Polk County town of Mulberry that generated more than 12 million
pounds of toxic waste in 1993.
Phosphate-rich Hillsborough
Country, also in west-central Florida, ranked second for the amount of
toxic waste released within its borders. Rounding out Florida’s toxic
top five are counties with chemical plants and paper mills--Bay and
Escambia in the Panhandle and Duval, which encompasses Jacksonville, in
northeast Florida.

'All the water's bad': In McDowell County, you have to get creative to find safe drinking water
June 17, 2021
To
get drinking water, Burlyn Cooper and his neighbors have to collect
runoff from the rock face of a mountain. It’s contaminated, but it’s all
they have.
BRADSHAW, W.Va. — Every week, Burlyn Cooper parks on
the edge of a winding two-lane road, unloads a dozen plastic jugs from
the trunk of his car, and uses a hose to fill them with the spring water
that drips from a mountain's exposed rock face. For Cooper and many of
his neighbors, the mountain's runoff is their most reliable, and
trusted, source of drinking water.
"I've got so used to it, I wouldn't know how to act, to turn the faucet on and have good water," he said. "I can't imagine it."
Cooper
and his wife, Hazel, once depended on wells for water. More than 43
million Americans use wells, which can be a plentiful source of clean
water. Today, however, the Coopers' two wells are too polluted to drink
from — the result, they suspect, of nearby natural gas extraction. The
once-clear water, which they now only use to wash themselves and water
their animals, is orange and sour-smelling. It leaves a thick sludge in
their sinks, rust-colored stains on their taps and clothes, and an
itchy, red rash on Burlyn's skin.

Water being pumped into Tampa Bay could cause a massive algae bloom, putting fragile manatee and fish habitats at risk
April 8, 2021
Millions
of gallons of water laced with fertilizer ingredients are being pumped
into Florida’s Tampa Bay from a leaking reservoir at an abandoned
phosphate plant at Piney Point. As the water spreads into the bay, it
carries phosphorus and nitrogen – nutrients that under the right
conditions can fuel dangerous algae blooms that can suffocate sea grass
beds and kill fish, dolphins and manatees.
It’s the kind of risk no one wants to see, but officials believed the other options were worse.
About
300 homes sit downstream from the 480-million-gallon reservoir, which
began leaking in late March 2021. State officials determined that
pumping out the water was the only way to prevent the reservoir’s walls
from collapsing. They decided the safest location for all that water
would be out through Port Manatee and into the bay.
Florida’s
coast is dotted with fragile marine sanctuaries and sea grass beds that
help nurture the state’s thriving marine and tourism economy. Those near
Port Manatee now face a risk of algal blooms over the next few weeks.
Once algae blooms get started, little can be done to clean them up.

Four
South Florida environmental nonprofits sent Gov. Ron DeSantis a letter
Wednesday urging him to veto a controversial Lake Okeechobee water
supply bill.
Opponents say SB 2508 contains an unnecessary
requirement that the governor and Legislature must approve water
management district decisions about water allocation; plus, the bill
yields too much control to entities planning to destroy wetlands.
Supporters say the bill provides a necessary check and balance...

The Effects: Dead Zones and Harmful Algal Blooms
https://www.epa.gov/nutrientpollution/effects-dead-zones-and-harmful-algal-blooms
Dead
zones are areas of water bodies where aquatic life cannot survive
because of low oxygen levels. Dead zones are generally caused by
significant nutrient pollution, and are primarily a problem for bays,
lakes and coastal waters since they receive excess nutrients from
upstream sources.
Excess nitrogen and phosphorus cause an
overgrowth of algae in a short period of time, also called algae blooms.
The overgrowth of algae consumes oxygen and blocks sunlight from
underwater plants. When the algae eventually dies, the oxygen in the
water is consumed. The lack of oxygen makes it impossible for aquatic
life to survive. The largest dead zone in the United States – about
6,500 square miles – is in the Gulf of Mexico and occurs every summer as
a result of nutrient pollution from the Mississippi River Basin.
When
some types of algae blooms are large and produce chemicals, or toxins,
the event is called a harmful algal bloom. Harmful algal blooms can
occur in lakes, reservoirs, rivers, ponds, bays and coastal waters, and
the toxins they produce can be harmful to human health and aquatic life.
Harmful algal blooms are mainly the result of a type of algae called
cyanobacteria, also known as blue-green algae.
Elevated nutrient
levels and algal blooms can also cause problems in drinking water in
communities nearby and upstream from dead zones. Harmful algal blooms
release toxins that contaminate drinking water, causing illnesses for
animals and humans.

Algae
https://plants.ifas.ufl.edu/plant-directory/algae/
Species Overview
Algae are a diverse set of organisms that can be found just about anywhere around the globe, from the artic circle to the underwater volcanic vents. These organisms conduct photosynthesis but do not have roots or leaves. Rather they are collections of cells that remain individual or connect together into colonies that can form mats or even resemble plants. Though unsightly at times, algae are an essential part of the food web and contribute significantly to dissolved oxygen in the water column.
Algae populations are driven, largely, by the amount of nitrogen and phosphorus in the water. But depending on what species of algae is present, green water can be a sign of a healthy and productive aquatic ecosystem.
Though this is a major oversimplification, we will primarily classify algae into four groups: (1) Unicellular (green), (2) filamentous, (3) blue-green, and (4) charophytes (plant-like).
Species Characteristics
Unicellular, green algae grow suspended throughout the water column and can indicate high levels of nitrogen and phosphorus, and high biological productivity. These are unicellular and don’t have any noticeable structure (unless you have a microscope), but will cause the water to take on a greenish or gritty appearance. These nutrient-rich environments are not necessarily bad as they will support a wide variety of wildlife, from plankton to invertebrates, to fish. However, the overgrowth of green algae can prevent light penetration through the water that is needed to support submersed plants. If no plants are present, as the algae populations cycle through the season, dissolved oxygen can range from high to low in a matter of days. This rapid cycling of oxygen can be troublesome to the aquatic ecosystem and fish kills may result.
Filamentous algae (Cladophora, Pithophora, and Spirogyra spp., and others) often form dense floating mats that can range from green to brown, to red. These mats can be thick and have hair-like quality to them. Generally speaking, these form on the bottom of relatively shallow or clear lakes that have sufficient light penetration to the bottom to support growth. Gases formed during photosynthesis get trapped in the mats, causing them to float to the surface. These algae can be particularly troublesome to desirable submersed plants as the algae cover them over and compete for sunlight. They are also unsightly and complicate fishing, swimming, and other recreation. Particularly as the older mats begin to rot the smell can be unpleasant, further adding to the nuisance of these algae.
Blue-green algae is a cyanobacteria that develops a recognizable blue-ish hue when blooming. If the bloom persists, the cells can begin to clump together and develop a noxious odor. Of primary concern, the blue-green algae microsystis can produce a powerful toxin (microsystin) that can be harmful to pets and humans. These algae are often managed in drinking water reservoirs as some of the compounds they produce have a bad taste at very small levels, in the parts-per-trillion range.
Charophytes, or plant-like algae, form very structured colonies that will appear rooted in the sediment with branch-like structures, very much looking like a plant. These are still algae; they are just very structured in their colonies. Kelp, a marine algae, looks very much like a plant but is a clonal algae. In freshwater some of these algae can grow to nuisance levels, impeding navigation and swimming. One example, chara algae, will often smell like garlic or onions and has an abrasive texture that can impede recreation.

Florida tops list for the most polluted lakes in the U.S., study finds
March 18, 2022
Florida has climbed to the top of another ignominious list, thanks to its hundreds of thousands of acres of dirty lakes.
Thick algae mats clogged the Pahokee Marina on Lake Okeechobee last year.
The state's waters have long been fouled by dirty stormwater and algae blooms fed by fertilizer run off from farms. Now a new study examining water quality across the U.S. shows Florida ranking first for the highest total acres of lakes too polluted for swimming or healthy aquatic life. That means water can have high levels of fecal matter and other bacteria that can sicken people , or have low levels of oxygen or other pollution that can harm fish and other aquatic life. The state ranked second for polluted estuaries.
The Environmental Integrity Project launched the project to track the progress of the Clean Water Act as it nears its 50th anniversary.
“Fifty years ago, we had the imagination and political will to face big problems and try to do something about them,” said Eric Schaeffer, the project's executive director and former head of the U.S. Environmental Protection Agency regulatory office . “We're hoping at this half-century mark that we can find the courage to recommit.”
The group based the findings on Florida’s 2020 water quality report filed with the U.S. Environmental Protection Agency. The same reporting from other states was used to compile the rankings. Ohio and the Great Lakes were excluded because they compile data on lakes differently.
The 1972 law made it a federal crime to directly discharge pollution into waters, but remained vague about runoff that drains into waters. That’s created decades of problems for states like Florida, where farms and dense urban areas line waterways.
Across the U.S., it’s also allowed industrialized agricultural operations to largely bypass pollution limits, Schaeffer said.
“A failure to confront agriculture is probably the biggest program failure in the Clean Water Act,” said Schaeffer, who resigned from his EPA post in 2002 after criticizing the Bush administration for gutting the Clean Air Act. “We have to confront the fact that agricultural runoff is really the leading cause of water pollution in the U.S. today. I don't think that was true so much 50 years ago.”
In Florida, nearly 900,000 acres of lakes are classified as impaired for swimming or healthy aquatic life. About 2,500 acres of estuaries are polluted, accounting for 99% of the total assessed.

Mine tailing disposal sites: contamination problems, remedial options and phytocaps for sustainable remediation
2017
Abstract
Mining
practices and the absence of proper mine land reclamation has led to
heavy metal contaminated sites with serious impact on the ecosystems and
risk for human health. The origin of the contamination is often
associated to mine tailing deposits because they are a source of the
acid mine drainage (AMD). These areas are devoid of vegetation due to
the harsh soil conditions that prevent the rooting of plant species. The
remediation of these areas followed by revegetation is necessary to
suppress the generation of the AMD and its negative effects on the
ecosystems. Conventional remediation technologies for heavy metal
contaminated sites are usually not applicable because of the high cost
associated with chemicals and energy requirements, as well as the long
treatment time to remediate large areas. In this study, the use of
phytocapping for the remediation of mine tailing deposits and abandoned
mine areas is reviewed. Phytocapping is cost effective, environmentally
friendly and has multifunctional role against various problems of mine
tailings: it provides erosion control, landscape rehabilitation,
enhances the soil properties for further colonization of other more
demanding vegetal species, reduces the leachability of metals downwards
the groundwater, and favors the immobilization of metals forming less
bioavailable species. The most critical step in phytocapping is the
developing of the first vegetative cover because of the biotoxicity of
the mine soil and mine tailings. Several amendment materials can be used
to ameliorate soil conditions creating a favorable environment for the
rooting of plants, as well as serving as a source of nutrients. Local
plant species with fast growing are preferable because their adaptation
to the soil and climate conditions favors their self-propagation.

Health of beloved Florida spring should improve after water plant's closure
Jan 31, 2023
Hernando
County leaders and others participated in a valve closing ceremony to
mark the closure of the facility, which is located behind the Walmart
Supercenter on US Highway 19.
The county closed the facility,
which had been in operation since 1967 because it was ultimately sending
water rich with nitrogen into spring.
Nitrogen and other types of nutrient pollution can cause algae to bloom in springs like Weeki Wachee.
According
to the Southwest Florida Water Management District, “large amounts of
algae growth can cause reduced water clarity and extreme fluctuations in
dissolved oxygen, which is stressful to aquatic life.”
Hernando
County said the water reclaimed at the Spring Hill site will now be sent
to another facility near the airport, where newer technology will scrub
more of the nitrogen from reclaimed water before it is used to irrigate
a local golf course.

Sulfur distribution and isotopic composition in peats from the Okefenokee Swamp, Georgia and the Everglades, Florida
1991
Abstract
Peat cores from three aquatic environments (freshwater, brackish and marine have been analyzed for organic, pyritic and sulfatic sulfur contents and isotope ratios. Peat collected from each environment has a unique combination of sulfur content, distribution and isotope ratio. Freshwater peat from the Okefenokee Swamp contains the least sulfur (0.26 to 0.48%, primarily organic sulfur) and is vertically uniform in sulfur content and isotope ratio. The organic sulfur isotope ratio of the Okefenokee pear (+ 12.3 to + 12.8 per mil) is similar to that of sulfate in associated surface waters. Cores from presently brackish and marine peats from the Florida Everglades have high organic, pyritic and sulfatic sulfur contents with vertical variability in sulfur content and isotope ration. The isotope ratio of organic sulfur in the brackish and marine peat is lighter than that of sulfate associated with their respective peat-forming environments. Organic sulfur in the marine peat is isotopically lighter than in the brackish peat. Freshwater peats subsequently overlain by sediment associated with brackish to marine waters may have a sulfur content, distribution and isotopic ratio indistinguishable from peats derived under brackish or marine conditions.
The primary source of sulfur in peats is dissolved sulfate associated with the peat-forming system. The sulfate concentration of the waters in which a peat forms is of major importance in determining the isotopic composition of the sulfur form found in peat. The content, distribution and isotopic ratio of low and high sulfur peats are similar to those reported for coals, indicating that the fundamental sulfur geochemistry of coals may have been established during the peat-forming stage of coalification. The organic sulfur content and isotope ratio of a coal may be useful in estimating the relative sulfate ion concentration of the waters present during the peat-forming stage of coalification where transgressive sequences are not involved. The sulfate ion concentration of paleowaters could be used to interpret the paleoenvironment during the peat-forming stage of coalification and thus, information about the organic sulfur content and isotope ratio of coals may prove useful in helping to assess coal quality in advance of mining.

Florida’s Vanishing Beaches: The fight against coastal erosion
July 20, 2022
According
to a June report by the Florida Department of Environmental Protection,
more than half of the 825 miles of coastline they surveyed are
critically eroded.
Earlier this year, you might remember seeing
the unbelievable video of a home collapsing into the Atlantic Ocean in
the Outer Banks. The house on a beach in Rodanthe is one of three that
succumbed to erosion.
Our national partner Newsy investigated how
bad the problem is in North Carolina. We teamed up with them and
learned that beaches on the West Coast of Florida have similar, if not
worse, erosion as Rodanthe...

A World of Vanishing Lakes
From the Dead Sea to a Louisiana lake that was sucked into the Earth, the stories behind the disappearances are varied
February 6, 2014
Scott Lake, Florida
This
central Florida lake drained away in just two weeks in June 2006 when a
sinkhole opened up. Scientists estimate that 32 tons of wildlife were
sucked into the Earth; some fish were left behind to rot on the exposed
lake bottom.
Nearby residents considered efforts to plug the
hole, but time took care of the problem for them. With the sinkhole now
naturally plugged back up with clay and silt, it's starting to fill with
water and gradually the lake is returning. But Florida’s geology makes
the state prone to sinkholes, so the lake’s permanence is not
guaranteed.

platform was created during the Eocene to Oligocene as the Gulf Trough
filled with silts, clays, and sands. Flora and fauna began appearing
during the Miocene. No land animals were present in Florida prior to the
Miocene.
Limestone over bedrock
The Floridian peninsula
is a porous plateau of karst limestone sitting atop bedrock known as the
Florida Platform. The emergent portion of the platform was created
during the Eocene to Oligocene as the Gulf Trough filled with silts,
clays, and sands. Flora and fauna began appearing during the Miocene. No
land animals were present in Florida prior to the Miocene.
The
largest deposits of rock phosphate in the United States are found in
Florida.[1] Most of this is in Bone Valley in central and west-central
Florida.[2]
Extended systems of underwater caves, sinkholes and
springs are found throughout the state and supply most of the water used
by residents. This type of terrain (geomorphology) that develops over a
carbonate platform or strata is called Karst Topography.
The
limestone is topped with sandy soils deposited as ancient beaches over
millions of years as global sea levels rose and fell. During the last
glacial period, lower sea levels and a drier climate revealed a much
wider peninsula, largely savanna.[3] While there are sinkholes in much
of the state, modern sinkholes most commonly form in the Tampa Bay area
and Central Florida.

Groundwater reorganization in the Floridan aquifer following Holocene sea-level rise
12 September 2010
Abstract
Sea-level fluctuations, particularly those associated with
glacial–interglacial cycles, can have profound impacts on the flow and
circulation of coastal groundwater: the water found at present in many
coastal aquifers may have been recharged during the last glacial period,
when sea level was over 100 m lower than present, and thus is not in equilibrium with present recharge conditions.
Here we show that the geochemistry of the groundwater found in the
Floridan Aquifer System in south Florida is best explained by a
reorganization of groundwater flow following the sea-level rise at the
end of the Last Glacial Maximum approximately 18,000 years ago. We find
that the geochemistry of the fresh water found in the upper aquifers at
present is consistent with recharge from meteoric water during the last
glacial period. The lower aquifer, however, consists of
post-sea-level-rise salt water that is most similar to that of the
Straits of Florida, though with some dilution from the residual fresh
water from the last glacial period circulation. We therefore suggest
that during the last glacial period, the entire Floridan Aquifer System
was recharged with meteoric waters. After sea level rose, the increased
hydraulic head reduced the velocity of the groundwater flow. This
velocity reduction trapped the fresh water in the upper aquifers and
initiated saltwater circulation in the lower aquifer.

Crystal River Mounds (150 BC)
2007
The
Crystal River site is located on the Central Gulf Coast of Florida near
the Three Sisters Springs. These springs are the source of the Crystal
River and the reason for its name. It is likely the Crystal River site
was chosen precisely due to its location near these springs.
The
site features at least three, flat-topped pyramid mounds, a large plaza,
two burial mounds, and three erect standing stones referred to as
stelae. The site is full of firsts. The flat-topped pyramid mounds are
the first such architectural features in Florida and perhaps the entire
Southeastern U.S. The mound-and-plaza site plan is the earliest such
site plan north of Mexico. A T-shaped flat-topped pyramid mound (Mound
H) is unique in the U.S. Its construction method, being made mostly of
limestone rocks, is rare in the southeastern U.S. and the first in
Florida. The three standing stone stelae, one carved with a human face,
are also unique and the only such objects north of Mexico.
The
central burial mound (Mound F) is surrounded by a circular embankment of
sand (Mound C), which also housed burials. The two structures form what
archaeologists call the Main Burial Complex. Exotic artifacts unearthed
from the central burial mound showed a trade connection with the
Hopewell civilization of Ohio. The Crystal River site was the
southernmost site with such exotic Hopewell artifacts.
Another
burial mound at the site (Mound G) showed no such exotic artifacts. This
difference in grave goods suggests one burial mound was for the elites
and the other for commoners.

Giant Sinkhole At Florida Plant Leaks Polluted Water Into State Aquifer
2016
Water containing low-level radiation and other pollutants has poured into Florida's primary drinking water aquifer through a gaping sinkhole 45 feet wide.
It happened at a plant owned by fertilizer giant Mosaic in central Florida's rural Polk County, Robin Sussingham of member station WUSF reports.
Last month, the sinkhole opened up at the plant under a gypsum stack — a pile of hazardous waste — as the Tampa Bay Times reported:
"It drained millions of gallons of acidic water laced with sulfate and sodium from a pool atop a 120-food gypsum stack. An unknown amount of gypsum, a fertilizer byproduct with low levels of radiation, also fell into the sinkhole, which is believed [to] be at least 300 feet deep."
Water continues to flow into a large sinkhole on the Mosaic Co. property
shown in this aerial photo on Thursday in Mulberry, Fla.

NAPLES, FLORIDA WATER QUALITY REPORT
https://www.epicwaterfilters.com/blogs/news/naples-utilities-florida-water-quality-report
Where
does Naples get its water from? All of the water that is used by the
Collier County Public Water Supply System (Naples, Florida) to produce
drinking water comes from wells. Water produced from wells is called
groundwater. The groundwater comes from porous, water-bearing
underground geologic layers of sand, gravel, or rock that have the
capability to produce water. These water-producing layers are called
aquifers. In Collier County, generally, as you go deeper into the
ground, the water in the aquifers becomes saltier.
List of Cities
& Towns that use this water system: Chokoloskee, Copeland,
Everglades City, Goodland, Immokalee, Marco Island, & Naples
The
Collier County Water Division operates two hybrid water treatment
plants that have the ability to process both fresh groundwater and
brackish groundwater from several different aquifers. Is Naples tap
water safe to drink? Does Naples put fluoride in the water?
Source: City of Naples, Florida
A list of contaminants in Naples, Florida Water Supply
(Detected above health guidelines*)
Chromium (hexavalent)
3rd
party independent testing found that this water utility exceeds health
guidelines for this drinking water contaminant. The movie Erin
Brockovich alerted the public to the great suffering the little town of
Hinkley, California experienced due to hexavalent chromium in their
drinking water. Today, Hinkley is little more than a ghost town thanks
to continued water contamination, health concerns, and plummeting
property values. Chromium (hexavalent) is a carcinogen that commonly
contaminates American drinking water. Chromium (hexavalent) in drinking
water may be due to industrial pollution or natural occurrences in
mineral deposits and groundwater. What are the risks of drinking tap
water with Chromium (hexavalent)? Cancer. A 2008 study by the National
Toxicology Program, part of the National Institutes of Health, found
that chromium-6 in drinking water caused cancer in laboratory rats and
mice. That study and other research led scientists at the California
Office of Environmental Health Hazard Assessment to conclude that
chromium-6 can cause cancer in people. Find out more about this
contaminant and how to remove it here.
Total trihalomethanes (TTHMs)
3rd
party independent testing found that this utility exceeds health
guidelines for this drinking water contaminant. Total Trihalomethanes
(TTHMs) are the result of a reaction between the chlorine used for
disinfecting tap water and natural organic matter in the water. At
elevated levels, TTHMs have been associated with negative health effects
such as cancer and adverse reproductive outcomes. Now a study by
government and academic researchers adds to previous evidence that
dermal absorption and inhalation of TTHMs associated with everyday tap
water use can result in significantly higher blood TTHM concentrations
than simply drinking the water does. What are the risks of drinking tap
water with Total Trihalomethanes (TTHMs)? Cancer. Studies from around
the world including the United States & Europe have found that
drinking tap water that carries Total Trihalomethanes increases the risk
of developing cancer. In animal studies, all trihalomethanes cause
liver, kidney and intestinal tumors. Find out more about this
contaminant and how to remove it here.
Fluoride
There is a
drinking water standard of 4 ppm for fluoride but there is no health
guideline for this contaminant and much is unknown about the effects of
fluoride long term on the human body. This water utility did not exceed
the drinking water standard for fluoride but fluoride was found in their
water. Fluoride occurs naturally in surface and groundwater and is also
added to drinking water by many water systems. The fluoride that is
added to water is not the naturally occurring kind, the main chemicals
used to fluoridate drinking water are known as “silicofluorides” (i.e.,
hydrofluorosilicic acid and sodium fluorosilicate). Silicofluorides are
not pharmaceutical-grade fluoride products; they are unprocessed
industrial by-products of the phosphate fertilizer industry (Gross!).
Since these silicofluorides undergo no purification procedures, they can
contain elevated levels of arsenic — more so than any other water
treatment chemical. In addition, recent research suggests that the
addition of silicofluorides to water is a risk factor for elevated lead
exposure, particularly among residents who live in homes with old pipes.
What are the risks of drinking tap water with Fluoride? Unknown. A
growing body of evidence reasonably indicates that fluoridated water, in
addition to other sources of daily fluoride exposure, can cause or
contribute to a range of serious effects, including neurological issues,
arthritis, damage to the developing brain, reduced thyroid function,
and possibly osteosarcoma (bone cancer) in adolescent males. Animal
studies indicate a moderate level of evidence that support adverse
effects on learning and memory in animals exposed to fluoride in the
diet or drinking water. Find out more about this contaminant and how to
remove it here.

Thermal pollution
https://en.wikipedia.org/wiki/Thermal_pollution
Thermal
pollution, sometimes called "thermal enrichment", is the degradation of
water quality by any process that changes ambient water temperature.
Thermal pollution is the rise or drop in the temperature of a natural
body of water caused by human influence. Thermal pollution, unlike
chemical pollution, results in a change in the physical properties of
water. A common cause of thermal pollution is the use of water as a
coolant by power plants and industrial manufacturers. Urban
runoff—stormwater discharged to surface waters from rooftops, roads, and
parking lots—and reservoirs can also be a source of thermal
pollution. Thermal pollution can also be caused by the release of
very cold water from the base of reservoirs into warmer rivers.
When
water used as a coolant is returned to the natural environment at a
higher temperature, the sudden change in temperature decreases oxygen
supply and affects ecosystem composition. Fish and other organisms
adapted to particular temperature range can be killed by an abrupt
change in water temperature (either a rapid increase or decrease) known
as "thermal shock". Warm coolant water can also have long term effects
on water temperature, increasing the overall temperature of water
bodies, including deep water. Seasonality effects how these temperature
increases are distributed throughout the water column. Elevated water
temperatures decrease oxygen levels, which can kill fish and alter food
chain composition, reduce species biodiversity, and foster invasion by
new thermophilic species.

History Of Phosphate Mining In Florida Fraught With Peril
2021
In
our ongoing series on phosphate mines, WUSF reports on the long,
tangled history of Florida's phosphate mines and the environment.
At
the construction entrance to the Piney Point phosphate plant - off
Buckeye Road in northern Manatee County, just south of the Hillsborough
County line - the smell of phosphate and gypsum hangs heavy in the air.
A
bulldozer is busy pushing sand into a hole from which more than 200
million gallons of tainted water flowed into Tampa Bay. This isn't the
first time this has happened. Accidents like this fill the history books
in Florida, including two here at this very site.
Manatee County Administrator Scott Hopes became the face of that disaster in late March.
ALSO READ: What Mosaic Is Doing With Its ‘Gypstack’ To Prevent Another Piney Point Disaster
"We're
down to about 340 million gallons that could breach in totality in a
period of minutes, and the models for less than an hour are as high as a
20-foot wall of water," he said during a news conference, when 300
families were evacuated for several days when it looked like a breach in
the gypstack was "imminent."
Long before Piney Point, phosphate
processing plants in the greater Tampa Bay region have caused some of
Florida's worst environmental disasters. Accidents like these fill the
history books in Florida.
Piney Point is not even close to the worst.
In
1997 a dam atop a gypsum stack at a Mulberry Phosphates fertilizer
plant broke during heavy rains, spilling 56 million gallons of acidic
wastewater into the North Fork of the Alafia River. Virtually everything
in the 42 miles between Mulberry and Tampa Bay was killed - including
more than 1 million fish. The company declared bankruptcy and shut down.
In
2004, high winds from Tropical Storm Frances whipped up waves atop a
180-foot-tall gypsum stack at Mosaic's phosphate plant in Riverview. The
waves bashed a big hole in the dike around the pond, sending 65 million
gallons of polluted water into Archie Creek, which flows into
Hillsborough Bay. Untold numbers of fish were killed, along with acres
of mangroves and seagrass.
In 2016, one of the deepest sinkholes ever
recorded in Florida opened beneath Mosaic's New Wales Plant in
Mulberry. More than 200 million gallons of polluted water spiraled into
the underground aquifer. No one knows where it went. It took the company
two years to seal the opening.
And at Piney Point in 2001, after
owner Mulberry Phosphates went belly up, thousands of gallons of
ammonia-laden waste poured from the stack into ditches leading into one
of the prime breeding areas for fish and marine life in Tampa Bay.
Ten years later, a rip in the lining of the stack here poured another 170 million gallons into the bay.

Pollution from Florida mining a concern with Hurricane Ian
2022
https://apnews.com/article/hurricanes-florida-storms-pollution-e82ff089f4ffc2e16c73c29e9818f58b
ST.
PETERSBURG, Fla. (AP) — The polluted leftovers of Florida’s phosphate
fertilizer mining industry, more than 1 billion tons in “stacks” that
resemble enormous ponds, are at risk for leaks or other contamination
when Hurricane Ian comes ashore in the state, environmental groups say.
Florida
has 24 such phosphogypsum stacks, most of them concentrated in mining
areas in the central part of the state. About 30 million tons of this
slightly radioactive waste is generated every year, according to the
Florida Industrial and Phosphate Research Institute...
Phosphate
has been mined in Florida since 1883. It’s used mainly for fertilizer to
produce food, animal supplements and a variety of industrial products.
Land used in mining is required to be “reclaimed,” or brought as close
as possible back to its original state.
The byproducts that wind
up in the stacks, however, have few uses acceptable to federal
regulators. They can contain radioactive uranium, thorium and radium
along with toxic metals such as barium, cadmium and lead, according to
the environmental group ManaSota 88.
Fertilizers are made from
phosphate rock that contains naturally occurring uranium and thorium,
which decay to radium, and radium decays to the radioactive gas radon,
the Environmental Protection Agency says. Class-action lawsuits have
claimed health effects for people living near the mining waste.
“Phosphate
companies have had over 70 years to figure out a way to dispose of
radioactive gypsum wastes in an acceptable manner, but they have yet to
do so,” said Glenn Compton, chairman of ManaSota 88...

Gizzard shad harvest reduces nutrient pollution in Lake George
August 23, 2019
PALATKA,
Fla., Aug. 23, 2019 ― The St. Johns River Water Management District’s
Lake George gizzard shad harvest removed approximately 5,176 lbs. of
phosphorus and 13,192 lbs. of nitrogen from the largest lake in the St.
Johns River system, located in Marion, Lake, Volusia and Putnam
counties.
“Gizzard shad removal is a cost-effective tool to
remove nutrients from Lake George,” said St. Johns River Water
Management District Executive Director Dr. Ann Shortelle. “We appreciate
our Governing Board’s commitment to funding turnkey projects such as
this to improve the health of the St. Johns River system, and we thank
Gov. DeSantis for making water quality protection one of his highest
environmental priorities.”
In response to the governor’s
executive order and emerging algal blooms in the lower St. Johns River,
district staff identified shad harvesting as a rapid and effective way
to reduce phosphorus in the lake, part of the St. Johns River system.
Staff identified unspent funds and the agency’s governing board approved
the Lake George harvest at its May meeting.
The gizzard shad
harvest took place from June 4 to July 16 and removed 628,173 pounds of
the rough fish from Lake George, which directly removed thousands of
pounds of nutrient pollution from the lake. Removing large numbers of
shad from a waterbody removes the nutrients contained in the fishes’
bodies.
Water quality data from Lake George suggest the reduction
in phosphorus recycling caused by shad removal is roughly seven times
the direct phosphorus removal benefit. District shad harvests on Lake
George between 2013 and 2018 removed more than 5 million pounds of fish
containing a total of 22,312 pounds of phosphorus.
Gizzard shad
feed on algae on the bottom of the lake, stirring up sediments and
clouding the water. Shad excrete nutrients back into the water,
recycling nutrients from the bottom that can feed more algae. Thus, by
removing these fish, additional nutrients will not be recycled into the
lake to impair its water quality.
Gizzard shad are a native fish
found in most Florida waters and account for 5 to 20 percent of the
total fish population in healthy Florida lakes. However, in
nutrient-rich, algae-dominated lakes, gizzard shad proliferate and can
account for more than 90 percent of the total fish population.
Harvesting
gizzard shad from Lake George is conducted during warmer months to
avoid potentially catching untargeted species, including American shad, a
species that is managed and protected under the Atlantic States Marine
Fisheries Commission.
The district works with commercial fishing
vendors to net gizzard shad. Sport fish caught in nets during the
harvests are immediately released. The program is permitted and
monitored by the Florida Fish and Wildlife Conservation Commission.

How catching 'junk' fish cleans up Central Florida lakes
2017
Net
a million pounds of shad annually and that's 8,000 pounds of phosphorus
out of the lake. Each pound of phosphorus can grow 500 pounds of algae.
So that's 4 million pounds of potential algae per year out of the way
of bottom grass, bass and other coveted lake life.

What Mosaic Is Doing With Its ‘Gypstack’ To Prevent Another Piney Point Disaster
2021
Three
months ago, a rupture at the former Piney Point phosphate plant sent
hundreds of millions of gallons of toxic water into Tampa Bay. We take a
tour of one towering "gypstack" to see what's being done to keep that
from happening again.
Dennis Black, the gypstack manager at The
Mosaic Company's phosphate processing plant in Bartow, guns a large
vehicle up the side of the dusty mountain.
"We're averaging just over 500 feet right now. We're permitted to go to 520," he says, over the roar of the SUV.
The stack is almost as tall as a 50-story building.
The view from atop the gypsum stack is regal.
The
Lakeland skyline pokes out to the north. Bok Tower in Lake Wales can be
seen to the east. On a clear day the towers of downtown Tampa scrape
the western horizon.

Silver Springs pollution is reaching unsafe levels, according to expected survey results
February 17, 2024
Robert
“Bob” Knight, the founder of FSI, said he fears Silver Springs will
meet the same fate as Gilchrest Blue Spring. In July, a sinkhole opened
in the spring and flooded the water with sediment. He said it’s all
empty and almost dead now. Nitrate levels are at a high, and about a
third of the spring’s flow is lost.
Chemical compounds in an area
spring are more than three times a safe level, according to an upcoming
report by the Florida Springs Institute. The compounds, called nitrates,
can kill plant life, cause algae blooms and pollute drinking water in
Silver Springs.
“Compared to what it used to be, [Silver Springs] is in very bad condition,” said Bill Hawthorne, an aquatic ecologist at FSI.
The
Silver Springs system, and over a thousand more springs in north
central Florida, supply 90% of the state’s drinking water. The Silver
Springs system is the largest artesian spring group in the United States
and is among the largest in the world.
FSI’s survey has
calculated the compounds at 1.15 milligrams per liter. Any level greater
than 0.35 causes plant death and pollutes the water, according to
Hawthorne.
“The two biggest threats we’ve seen are nitrogen
pollution and groundwater pumping,” Hawthorne said. “There’s been a
large reduction in flow, which is vital for everything that calls the
spring home.”
Prior to farming and development in the area, the chemical compounds were much lower, at 0.04 milligrams per liter, he said.

Can Coal Ever Be Clean?
April 2014
It’s the dirtiest of fossil fuels. We burn eight billion tons
of it a year, with growing consequences.
The world must face the question.
American Electric Power’s Mountaineer Plant, on the Ohio River in New Haven, West Virginia, inhales a million pounds of Appalachian coal every hour. The coal arrives fresh from the ground, on barges or on a conveyor belt from a mine across the road. Once inside the plant, the golf-ball-size lumps are ground into dust as fine as face powder, then blown into the firebox of one of the largest boilers in the world—a steel box that could easily swallow the Statue of Liberty. The plant’s three steam-powered turbines, painted blue with white stars, supply electricity round the clock to 1.3 million customers in seven states. Those customers pay about a dime per kilowatt-hour, or roughly $113 a month, to power the refrigerators, washers, dryers, flat screens, and smartphones, to say nothing of the lights, of an average household. And as Charlie Powell, Mountaineer’s plant manager, often said, even environmentalists like to keep the lights on.
The customers pay not a cent, however, nor does American Electric Power (AEP), for the privilege of spewing six to seven million metric tons of carbon dioxide into the atmosphere every year from Mountaineer’s thousand-foot-high stack. And that’s the problem. Carbon is dumped without limit because in most places it costs nothing to do so and because there is, as yet, no law against it in the U.S. But in 2009 it looked as if there might soon be a law; the House of Representatives had already passed a bill that summer. AEP, to its credit, decided to get ahead of it.
That October, Mountaineer began a pioneering experiment in carbon capture. Powell oversaw it. His father had worked for three decades at a coal-fired power plant in Virginia; Powell himself had spent his career at Mountaineer. The job was simple, he said: “We burn coal, make steam, and run turbines.” During the experiment, though, it got a bit more complicated. AEP attached a chemical plant to the back of its power plant. It chilled about 1.5 percent of Mountaineer’s smoke and diverted it through a solution of ammonium carbonate, which absorbed the CO₂. The CO₂ was then drastically compressed and injected into a porous sandstone formation more than a mile below the banks of the Ohio.
The system worked. Over the next two years AEP captured and stored more than 37,000 metric tons of pure carbon dioxide. The CO₂ is still underground, not in the atmosphere. It was only a quarter of one percent of the gas coming out the stack, but that was supposed to be just the beginning. AEP planned to scale up the project to capture a quarter of the plant’s emissions, or 1.5 million tons of CO₂ a year. The company had agreed to invest $334 million, and the U.S. Department of Energy (DOE) had agreed to match that. But the deal depended on AEP being able to recoup its investment. And after climate change legislation collapsed in the Senate, state utility regulators told the company that it could not charge its customers for a technology not yet required by law.
In the spring of 2011 AEP ended the project. The maze of pipes and pumps and tanks was dismantled. Though small, the Mountaineer system had been the world’s first to capture and store carbon dioxide directly from a coal-fired electric plant, and it had attracted hundreds of curious visitors from around the world, including China and India. “The process did work, and we educated a lot of people,” said Powell. “But geez-oh-whiz—it’s going to take another breakthrough to make it worth our while.” A regulatory breakthrough above all—such as the one Obama promised last summer—but technical ones would help too.
Capturing carbon dioxide and storing or “sequestering” it underground in porous rock formations sounds to its critics like a techno-fix fantasy. But DOE has spent some $6.5 billion over the past three decades researching and testing the technology. And for more than four decades the oil industry has been injecting compressed carbon dioxide into depleted oil fields, using it to coax trapped oil to the surface. On the Canadian Great Plains this practice has been turned into one of the world’s largest underground carbon-storage operations.
Since 2000 more than 20 million metric tons of carbon dioxide have been captured from a North Dakota plant that turns coal into synthetic natural gas, then piped 200 miles north into Saskatchewan. There the Canadian petroleum company Cenovus Energy pushes the CO₂ deep into the Weyburn and Midale fields, a sprawling oil patch that had its heyday in the 1960s. Two to three barrels of oil are dissolved out of the reservoir rock by each ton of CO₂, which is then reinjected into the reservoir for storage. There it sits, nearly a mile underground, trapped under impermeable layers of shale and salt.
For how long? Some natural deposits of carbon dioxide have been in place for millions of years—in fact the CO₂ in some has been mined and sold to oil companies. But large and sudden releases of CO₂ can be lethal to people and animals, particularly when the gas collects and concentrates in a confined space. So far no major leaks have been documented at Weyburn, which is being monitored by the International Energy Agency, or at any of the handful of other large storage sites around the world. Scientists consider the risk of a catastrophic leak to be extremely low.
They worry more about smaller, chronic leaks that would defeat the purpose of the enterprise. Geophysicists Mark Zoback and Steven Gorelick of Stanford University argue that at sites where the rock is brittle and faulted—most sites, in their view—the injection of carbon dioxide might trigger small earthquakes that, even if otherwise harmless, might crack the overlying shale and allow CO₂ to leak. Zoback and Gorelick consider carbon storage “an extremely expensive and risky strategy.” But even they agree that carbon can be stored effectively at some sites—such as the Sleipner gas field in the North Sea, where for the past 17 years the Norwegian oil company Statoil has been injecting about a million tons of CO₂ a year into a brine-saturated sandstone layer half a mile below the seabed. That formation has so much room that all that CO₂ hasn’t increased its internal pressure, and there’s been no sign of quakes or leaks.
American Electric Power’s Mountaineer Plant, on the Ohio River in New Haven, West Virginia, inhales a million pounds of Appalachian coal every hour. The coal arrives fresh from the ground, on barges or on a conveyor belt from a mine across the road.

‘Sewer crisis in the state of Florida’
2019
Storms and aging infrastructure contribute to massive spills
More than 900,000 gallons of raw sewage flowed into Sarasota Bay after a violent December storm forced open a city pipe.
Summer
rain in Daytona Beach and equipment failure in Jacksonville each
prompted more than a quarter-million gallons of human waste to spill
from sewers last year.
In Boca Raton, a pressurized pipe gushed
out nearly 50,000 gallons of untreated wastewater, while another 55,000
gallons spewed from a DeFuniak Springs manhole into nearby Bruce Creek.
These
sewage spills are emblematic of failing wastewater systems across
Florida, which is grappling with aging infrastructure and no clear
solutions for funding a fix.
An analysis of those reported spills
shows Florida’s sewers failed nearly 23,000 times over the past 10
years — a clip of more than six sewer spills each day.
The systems leaked enough human waste to fill about 2,400 Olympic-size swimming pools.
The
top cause for the spills was breakage, often from tree root intrusion
and exacerbated by the deterioration of aging lines, nearing 80 years
old in some communities. Flooding and power loss from storms also
pounded the systems in coastal areas, causing massive amounts of sewage
to flow out.

Ban Sewage Sludge Now!
Oct 26, 2018
Algae in Blue Cypress Lake, an Outstanding Florida Waterway
On
October 15, 2018, our Headwaters Advisory Committee delivered an
editorial to local papers highlighting the MANY concerns that remain
regarding the application on Sewage Sludge to property in our
headwaters, and the Technical Advisory Committee that has been formed to
study the issue. Read our concerns below, and help us stay engaged.
What happens in our headwaters impacts the entire basin.
"Florida waters are suffering from a growing pollution threat – sewage
sludge. Also known as biosolids, this sludge is a byproduct of the
process to clean our wastewater. In an effort to dispose of this waste
inexpensively, utilities often contract with third party haulers to
transport and spread excess sludge on to agricultural lands. This
unsustainable disposal practice exposes adjacent waters to those
agricultural areas to high levels of pollution from runoff.
In 2007, the Florida Legislature essentially banned the land disposal of
sewage sludge in the Lake Okeechobee watershed. This legislation was
enacted in response to the serious nutrient pollution problem that was
severely degrading the lake’s water quality. As a result, the state
began permitting the redistribution of South Florida’s sewage sludge to
areas with fewer restrictions north of the lake.
The Florida
Department of Environmental Protection (FDEP) confirmed that on average
more than 70,000 tons of sewage sludge has since been annually permitted
to be disposed within the Upper Basin of the St. Johns River, which
includes Brevard, Indian River and Osceola Counties. In 2016, this
represented more than 73% of the Class B biosolids permitted for land
application in the entire state.
This state-sanctioned
spreading of sewage sludge is now degrading the St. Johns River’s water
quality and threatening human health.
Did they believe that
they could simply relocate sewage sludge to a different watershed
without a similar degradation of water quality and increased threats to
human health?
In addition, biosolids are undermining the
significant investments made by downstream local governments to remove
nutrient pollution from the St. Johns and its lakes and tributaries. The
state-required Basin Management Action Plan (BMAP) for the middle
section of the St. Johns River determined that over 96% of the total
nitrogen loading and 95% of the total phosphorous loading in the Middle
Basin of the river comes from upstream sources. The addition of
biosolids-related nutrient pollution will only make it much more
expensive and difficult for Central Florida communities and businesses
to reduce nutrients by close to 38%, as required by the state.
In response to the public outcry, the FDEP recently formed a Biosolids
Technical Advisory Committee (TAC) to further evaluate this issue. We
are pleased to see the state finally taking some action, but this
committee is simply evaluating the same technical issues and research
that were previously determined to warrant legislative restrictions on
this harmful practice in South Florida. While good for the Lake
Okeechobee watershed, this unfortunately left the remainder of the state
exposed to the water quality impacts of sewage sludge. It should come
as no surprise that the application of over 70% of the state’s biosolids
to agricultural lands within the St. Johns watershed would have the
same devastating results.

Residual
sludge from treating waste water has been turned into a money-spinner
but what are the costs to health of ‘the most pollutant-rich manmade
substance on Earth’?
7 Oct 2019
By some estimates, Americans send about 300m pounds of feces daily from the nation’s toilets to wastewater treatment plants.
While
the water is cleaned and discharged, the remaining toxic sewage sludge
stays at the treatment plant, and it’s what Sierra Club environmentalist
Nancy Raine calls “the most pollutant-rich manmade substance on Earth”.
This
“biosolid” sludge is expensive to dispose of because it must be
landfilled, but the waste management industry is increasingly using a
money-making alternative – repackaging the sludge as fertilizer and
injecting it into the nation’s food chain.
Now the practice is
behind a growing number of public health problems. Spreading
pollutant-filled biosolids on farmland is making people sick,
contaminating drinking water and filling crops, livestock and humans
with everything from pharmaceuticals to PFAS.

Petroleum sludge treatment and disposal techniques: a review
24 March 2022
Abstract
Petroleum
sludge is a solid emulsified waste and contaminant commonly produced in
the petroleum industry. In the recent past, there has been increased
business growth in the oil sector, resulting in increased volumes of
oily sludge characterized by high viscosity and toxicity. Therefore,
sludge treatment before discarding is extremely necessary. This review
seeks to highlight various conventional and evolving approaches in the
treatment, recovery, and disposal of petroleum sludge and assess their
suitability under various conditions.

Sewage pollution, declining ecosystem health, and cross-sector collaboration
2021
Abstract
It is well established that a global sanitation crisis threatens humans. By comparison, much less attention has been given to address the effects of this crisis on the health of ecosystems. We provide examples of how sewage can affect natural ecosystems and where hotspots in sewage contamination commonly overlap with these habitats. We highlight these issues for some of the major ecosystems spanning across terrestrial, aquatic, and coastal realms. Recent studies reveal that untreated and poorly treated sewage elevates concentrations of nutrients, pathogens, endocrine disruptors, heavy metals, and pharmaceuticals in natural ecosystems. We show many large areas (10,000's of km2) across the globe with high levels of sewage contamination and that these contamination hotspots overlap extensively in occurrence with coral reefs, salt marshes, and fish-rich river systems. Given the global extent of sewage pollution in and near natural habitats, conservation biologists and managers must address this threat. However, because of its size, conservationists cannot solve this problem alone. We therefore argue that conservation must combine forces with the human health sector to create cross-disciplinary synergisms in innovation and efficiency. New sewage management solutions are emerging, such as waste-free toilets and resource recovery to generate fuel and drinking water; but more innovation is needed - a demand that will most effectively be reached through cross-sector collaboration.

Gainesville neighborhood on pollution notice after 10,000 gallons of flood and wastewater released into Hogtown Creek
Sep. 21, 2021
GAINESVILLE, Fla. (WCJB) - Gainesville residents who live near Hogtown Creek are facing a problem they’re all too familiar with.
On Sunday, GRU arrived at NW 10th Ave. where cleanout pipes released at least 10,000 gallons of flood and wastewater.
One man who’s lived on this street for three years said flooding is a constant problem.
“It’s been going on for a while, and I don’t go down there anymore because of those signs,” said Adam Pearce.
Pearce said because of where his house sits on the street, he’s safe from the sewage overflow.
He
said one of his neighbors at the end of the street had sewage flood
into their home. He said he’s seen the different ways this has affected
his neighbors’ lives.
“He’s got three kids. He can’t go outside
out front so he’s gotta kind of go out back and do baseball out there
because the sewage warnings and water damage,” said Pearce.
GRU said areas experiencing wastewater releases, like this, have received between 10 to 12 inches of rain over the last month.

GADSDEN COUNTY, Fla. (WTXL) — Two wastewater plant facilities in Gadsden County experienced water overflows this weekend.
According
to a Florida Department of Environmental Protection pollution notice
that was released Saturday, the Quincy Wastewater Treatment Plant began
overflowing the facility flow equalization tanks at around 7:30 p.m.
Friday because of the heavy rain that accumulated in the area.
The news release notes that the facility’s influent pumps were running, but could not keep up with the high flows.
The facility overflowed until 2 p.m. Saturday.
The FDEP estimates that 100,000 gallons escaped into the Quincy creek.
The overflows were almost contained, but the on and off rains led to the overflows to back up.

Of course, there was no outcry across the city since transparency was non-existent.
In
2009, the City of Tallahassee was placed under a Florida Department of
Environmental Protection (FDEP) expensive enforcement consent order for
numerous and voluminous sewage spills, much of which end up in storm
water ditches leading to Munson.
November 2021, 466,000 gallons
flowed through Hartsfield Village into the Central Drainage Ditch.
Contrary to my requests of city staff to track the movement of raw
sewage from north Tallahassee to Lake Munson, staff stopped behind TCC,
even with high eColi measurements.
Another 10 spills of 100,000 gallons flowed in 2021; yet, no transparency. Approximately 150,000 gallons spilled in 2020.

Lake Munson has gone from pristine to polluted. Can a drawdown change the trajectory?
Advocates, residents want county to remove what they see as toxic sediment
2022
The view over Lake Munson from Donna McKenzie’s armchair has changed a lot in the last 47 years.
Her husband, Ray, once fished and hunted ducks on the lake.
The
water used to be clear and free from the green scum accompanying the
pollution that has turned the lake toxic in recent years.
“It’s
really sad because I’ve been retired for 20 years and it’s like I’ve
been sitting here waiting for 20 years watching it go down,” Donna
McKenzie said from her home on the southwest shoreline.
The wait
for action may be over as the county in November began to release water
from the lake in an effort to combat the pollution that has resulted in
fish kills, algal blooms and partial closures of Lake Munson.

Is Perdido Bay in peril? Is it too late to protect it?
2019
Despite
Escambia County's outward beauty, our community has long been plagued
by pervasive pollution from industrial plants, landfills, septic tanks
and the like.
Pollution was so bad that in 1999, a special grand
jury was convened to assess local air and water quality. The jury found
that local regulators were falling down on the job, that local elected
officials were serving corporations rather than citizens and that we
needed to take immediate action to stem the tide of toxins in our
community.
The grand jury issued an array of recommendations to
improve pollution control, environmental monitoring, government
accountability and other issues, but 20 years later, we're still seeing a
lot of the same old problems.

Florida's Indian River Lagoon Is A "Killing Zone" Of Mass Animal Deaths: Report (VIDEO)
2013
Day
after day, dolphins floated up dead, emaciated down to their skeletons.
Florida's Indian River Lagoon, considered one of the most diverse
ecosystems in North America, was in dire crisis.
And it wasn't
just the 46 dead bottlenose dolphins. The casualty list is long and
depressing: gone are 47,000 acres of sea grass beds, 111 manatees, and
300 pelicans, reports Fox News.
It's been described as a "killing zone" and a "mass murder mystery" that is perplexing biologists.
The
Tampa Bay Times reports that scientists believe it may be due to one or
several causes: fertilizer-laced stormwater runoff, polluted water
dumped from Lake Okeechobee by U.S. Army Corps of Engineers, climate
change and effects on acidity, changes in water temperature and salt
levels, and overflow from contaminated mosquito-control ditches.
The
Harbor Branch Oceanographic Institute at Florida Atlantic University
was counting on $2 million in state funds to study the dead bodies
piling up at Indian River Lagoon.
Except Gov. Rick Scott vetoed
the research project in May, writing in his veto letter “While some
water projects may also contribute to a statewide objective, not all
projects demonstrate an ability to contribute to a statewide
investment.”
Since Scott took office in 2009, his smaller
government approach has slashed regulation and conservation programs,
reports the Broward New Times.

Crisis in the Indian River Lagoon: Solutions for an Imperiled Ecosystem
There is an ecological crisis in Indian River Lagoon. Large quantities of water with high levels of nutrient pollution from Lake Okeechobee and the St. Lucie Basin are being discharged to tide, leading to toxic algae blooms in the Lagoon’s waters. There have been numerous, mysterious reports of deaths of Pelicans, manatees, and dolphins in the area. Harmful bacteria have also been detected in some areas, making the water dangerous for human contact.
A parallel story is taking place on Florida’s Southwest coast. Water from Lake Okeechobee and the Caloosahatchee Basin are being flushed into the Caloosahatchee River, and as with the Indian River Lagoon, the discharges are contributing to algae blooms in the Caloosahatchee Estuary’s ecosystem.
In its natural state, water in the northern Kissimmee Basin meandered south to Lake Okeechobee, flowing into Everglades National Park and eventually Florida Bay. This water had very low levels of phosphorus and nitrogen.
Before human alteration to the ecosystem, the Kissimmee Valley would take six to eight months to release wet season loads into Lake Okeechobee. Now this same water drainage takes place within one month, making the Lake rise at an unnaturally rapid pace.
Fertilizer and storm water add phosphorus and nitrogen to the Okeechobee watershed. The water moves so quickly that it cannot be naturally cleansed before flowing downstream. The Indian River Lagoon and the Caloosahatchee Estuary also receive local runoff, which contribute high flows of nutrient-laden water into the estuaries.
Lake Okeechobee’s optimum water level for the ecosystem and for public safety is between 12.5 and 15.5 feet. Higher levels have drowned out as much as 70 square miles of plant communities, damaging foraging, breeding, and nesting habitats for iconic wildlife such as the endangered Everglade Snail Kite.
In addition, the 75-year old Herbert Hoover Dike surrounding the Lake cannot tolerate very high water levels without increasing the risk of a breach. A breach of the levee would expose the nearby towns of Pahokee, South Bay, and Clewiston to dangerous flooding. The United States Army Corps of Engineers is currently repairing the levee, but completion is decades away and it is uncertain how high the water will be able to be held once repairs are complete.
The danger from high water levels in the Lake is the reason for the increased mandatory releases to the coastal estuaries. The solution is to clean water and keep it in the ecosystem rather than discharging it to the coast.

Florida’s Indian River Lagoon Crisis: Unveiling the Hidden Dangers of Toxic Algae Blooms
2024
FAU Harbor Branch scientists discover distinctive patterns of cell damage linked to toxins in Florida’s Indian River Lagoon.
The Indian River Lagoon (IRL) in Florida, stretching 156 miles long, is bordered by five counties and contains five inlets linking it to the Atlantic Ocean. In recent times, this estuary has faced several phytoplankton bloom incidents, triggered by rising seasonal temperatures and environmental factors.
Florida’s Indian River Lagoon faces increasing phytoplankton blooms,
leading to toxic conditions. A study by Florida Atlantic University
revealed varying toxicity levels and the presence of both known and
potentially new toxins, emphasizing the importance of monitoring for human health implications. Toxic algae blooms on the water surface.

Fracking Florida
Fracking Florida is a website created by the Florida-based non-profit environmental policy and human rights organization, The Center for Human Rights and Environment, and is devoted to promote the exchange of information about the social and environmental implications of bringing hydraulic fracturing (fracking) activity to the State of Florida.
Because Florida is a State where oil and gas has been extracted successfully in the past, it is likely that oil and gas companies will try to bring hydraulic fracturing to the State, in fact, they already have.
Through the dissemination of information it is our intention to inform Florida residents of the risks and impacts posed by hydraulic fracturing operations with the ultimate goal of protecting Florida’s natural resources and delicate ecological systems, and guaranteeing the health and safety of Florida residents.
Where would you get Fracked? Below is a map (source: Florida Department of Environment) of where the oil and gas industry has sought to extract fossil fuels in the State. While not all of these sites produced oil or gas, with hydraulic fracturing technologies, some of these may now be able to produce fossil fuel … any one of these places is a potential site for fracking exploration and possibly, if shale gas and oil were found at those site, for fracking. The most likely places where fracking would initially get underway are those places where there has been oil or gas extraction in the past, including for example, Escambia, Santa Rosa, Collier, Lee, Hendry, and Lee counties. But even if you happen to live near a county line to one of these counties, and there is an oil or gas deposit nearby in one of these neighboring counties, through the extension of horizontal drilling techniques which can explore for miles underground in horizontal directions and due to the typical impacts of fracking could easily affect your area, and that might include Miami-Dade, Broward, Glades, Okaloosa, and others. Those are the “most likely” and immediate scenarios for fracking explorations.
The conclusion is, no matter where you live in Florida, there is a potential for the oil and gas industry to at the very least, test the waters for potential of non-conventional oil and gas. If you hear about Florida Fracking possibly coming your way, and you’re concerned that this activity might impact you, get engaged, talk to your local city council members, write to your Legislative Representatives and make sure your voice is heard.
You can find information on this website to inform yourself about the likely impacts of hydraulic fracturing if it were to come to Florida.

South Florida’s Dirty Secret Is Oil
March 18, 2021
https://www.nrdc.org/bio/alison-kelly/south-floridas-dirty-secret-oil
“Paradise
Coast” is how the tourism industry often refers to the Everglades,
Naples, and Marco Island parts of south Florida. As many city dwellers
flee states with cold winters and expensive costs of living looking to
quarantine in this paradise, there is a dirty little secret lurking in
the Florida swamp—impending oil development.
Many new residents
and tourists come to Florida to experience the state’s natural wonders
like Everglades National Park, Big Cypress National Preserve, Ten
Thousand Islands National Wildlife Refuge, and Florida Panther National
Wildlife Refuge. They come to hike, view wildlife, kayak, boat, and
fish. What they don’t know is that beneath many of these public lands in
Florida, including Big Cypress, there is oil—and it’s privately owned.
Much
(but not all) of this oil is owned by corporations run by the
politically powerful Collier family, after whom Collier County is named.
Collier-related corporations also engage in real estate development,
including a new 45,000-acre town, in endangered Florida panther habitat.
The Intercept has recently reported on the Collier entities’
development of endangered species’ habitats. And the Colliers have also
set their sights on accessing Florida panther habitat in Big Cypress in a
continued quest for oil.
Although there are two legacy oil
drilling sites in Big Cypress National Preserve—Bear Island and Raccoon
Point—the Colliers’ lessee, Burnett Oil Company, wants to expand oil
drilling at Raccoon Point and develop another entirely new area of the
Preserve, consisting of wetlands and namesake cypress trees.
The U.S. Government Tried to Buy Out the Colliers’ Mineral Rights Under Big Cypress
Big
Cypress National Preserve is a “split estate” where the federal
government owns the surface of the preserve and private entities,
including Collier entities, own the oil and gas beneath the surface. In
the early 2000s, under President George W. Bush and his brother, Florida
Governor Jeb Bush, there was an attempt to strike a deal to buy mineral
rights from the Collier entities for Big Cypress, Ten Thousand Islands
National Wildlife Refuge, and Florida Panther National Wildlife Refuge.
The deal fell through after a Department of Interior whistleblower
raised concerns that the agency overvalued the mineral rights and did
not follow applicable agency rules. The complaint was referred to the
Interior’s Office of Inspector General, which produced a report raising
several claims.
Interior’s Inspector General found Collier
entities only own around two-thirds of the private mineral rights yet
the deal contemplated compensation for 100%. Even more concerning is the
report’s finding that Collier entities may have already been
compensated in previous transactions for some or all of the mineral
interests that they sought compensation for in the early 2000s. Given
all the uncertainties in valuing the oil and gas rights, the Inspector
General recommended that, should Interior consider acquiring Big
Cypress’s private mineral interests again, the Department consider
condemnation. That’s what the enabling legislation, establishing the
Preserve as a National Park Unit, contemplated.
Since the federal
government failed to buy out private oil and gas rights beneath Big
Cypress, there has been no action on the Inspector General’s claims.
This is a big deal because, generally, when oil companies want to
extract oil and gas from public lands and waters, they enter into lease
agreements with the federal government and pay certain fees and
royalties on the fossil fuels they extract. In the case of federally
owned oil and gas, the U.S. taxpayers collect a share of the profits
based on the value or volume of the oil and gas extracted.
But in
the case of Big Cypress, the Collier entities’ lessee, Burnett Oil
Company, only had to obtain an access permit from the National Park
Service (in addition to state-issued permits) to hunt for oil in the
Preserve, which it did in 2017 and 2018, as we previously reported. In
order to drill, Burnett Oil Company must apply for an operations permit
from the National Park Service, but since the mineral rights are
privately held and below the surface, it needs no lease with the federal
government. In short: because Collier’s mineral rights are private,
neither the federal government nor the taxpayer will receive any
royalties from oil extracted in Big Cypress.
And Collier entities
have begun a lobbying effort to try to make sure they are compensated
if state or local governments try to impact their efforts to drill for
oil. As recently reported, a registered lobbyist for certain Collier
companies drafted proposed bill language and sent it to Florida Senator
Ray Rodrigues, for what became proposed Senate Bill 1380 "Relief From
Burdens on Real Property Rights.” If this bill passes, it will amend the
“Bert J. Harris, Jr., Private Property Rights Protection Act” in
Section 70.001 of the Florida Statutes. The existing law created “a
separate and distinct cause of action from the law of takings, the
Legislature herein provides for relief, or payment of compensation, when
a new law, rule, regulation, or ordinance of the state or a political
entity in the state, as applied, unfairly affects real property.”
Senator Rodrigues’ proposed amendment would ensure that the law applies
to privately held oil and gas.
There are other bills pending in
the 2021 Florida Legislative Session, such as Senate Bill 722, which
would prohibit the Florida Department of Environmental Protection from
granting permits for the drilling of wells for oil or gas within the
Everglades Protection Area. But this area does not include Big Cypress
National Preserve. Florida minority Democratic Leader Senator Gary
Farmer has introduced Senate Bill 546—“Stop Fracking Act"—that would
prohibit “extreme well stimulation,” including certain types of fracking
and acidizing. The senator also opposes oil drilling in Big Cypress.
Burnett Oil Company Seeks Federal Water Permits to Facilitate Oil Drilling
Burnett
Oil Company must have liked the results of its damaging oil exploration
activities in the Preserve because it has applied for permits to fill
in wetlands to build new oil drilling well pads and access roads. It is
seeking these permits under Florida’s Section 404 Clean Water Act
permitting program. Note that in the eleventh hour of the Trump
Administration, the Environmental Protection Agency approved the state
of Florida’s application to assume this permitting program. There is
federal court litigation challenging that move, and the Miccosukee Tribe
of Indians of Florida has raised serious concerns about the state’s
takeover of this permitting program. The tribe indicated that it also
plans to submit comments on Burnett Oil’s new development proposal.
There are hundreds of known cultural and archaeological resources
located in the Preserve and one of Burnett Oil’s proposed new well pads
is located adjacent to a Miccosukee reservation.
According to
Collier Resources Company, the National Park Service allows oil
exploration and development “as long as the activities comply with
strict environmental protection measures.” However, state and federal
government permitting requirements for the oil exploration so far have
failed to prevent extensive damage and these permits are not being
“strictly” enforced.
Here’s an example: other permittees in
Florida proposing to impact wetlands must provide compensatory
mitigation. They have to assess ecological functions provided by
wetlands and other surface waters using a standard procedure called the
Uniform Mitigation Assessment Method (UMAM), calculate the amount those
functions are reduced by a proposed impact, and the amount of mitigation
they would need to do to offset that loss. State regulators usually
require mitigation plans in advance of any impacts to wetlands. But when
Burnett Oil conducted seismic testing in Big Cypress, it was not
required to provide compensatory mitigation before driving 33-ton
vehicles off-road through Preserve wetlands to hunt for oil. Indeed,
four years after Burnett began exploring for oil in big Cypress, the
company has not completed compensatory mitigation for its wetland damage
in Big Cypress using Florida’s Uniform Mitigation Assessment Method.
Now
Burnett Oil Company is proposing the same mitigation approach for oil
development in its state Section 404 Clean Water Act application. And
why not? Wetland mitigation requires time and money, and, thus far, the
oil company is not being required to prove it can compensate for the
loss of wetland functions under UMAM.
The Biden-Harris Administration Should Review, and if Necessary, Halt, Burnett Oil’s Drilling Plans
Despite
the damage Burnett Oil caused in its first phase of exploration and its
failure to complete mitigation for that harm to wetlands, the National
Park Service Big Cypress National Preserve Superintendent said we can
anticipate public release of Burnett Oil’s operations permit application
to drill for oil in Big Cypress in late April or early May 2021.
This
rush to process permit applications to accommodate oil drilling in the
early days of the Biden-Harris Administration could jeopardize its
comprehensive review and reconsideration of Federal oil and gas
permitting and leasing practices, including potential climate and other
impacts associated with oil and gas activities. The Administration is
also working on strengthening Tribal consultation and Nation-to-Nation
relationships, and, therefore, the concerns expressed by the Miccosukee
Tribe of Indians of Florida and the Seminole Tribe of Florida must be
heard and addressed. NRDC submitted Freedom of Information Act (FOIA)
requests to the National Park Service during the Trump Administration,
seeking information on Burnett Oil’s first phase of exploration and
legacy oil drilling in the Preserve to better understand the impacts.
The National Park Service should fulfill those requests.
The
National Park Service should not permit new oil drilling in Big Cypress
National Preserve “[i]n order to assure the preservation, conservation,
and protection of the natural, scenic, hydrologic, floral and faunal,
and recreational values of the Big Cypress Watershed . . . and to
provide for the enhancement and public enjoyment thereof” as
contemplated by Congress in the Preserve’s enabling act. At a minimum,
it should pause decisions until after:
The Biden-Harris Administration completes a comprehensive review of the Federal oil and gas program;
The Department of the Interior initiates an investigation to follow up
on the claims made by its Office of Inspector General regarding the
possible prior purchase of private mineral rights beneath Big Cypress;
The National Park Service fulfills outstanding FOIA requests regarding
past and present oil exploration and development in Big Cypress;
The National Park Service engages in meaningful government-to-government Tribal consultation;
The National Park Service prepares a detailed Environmental Impact
Statement (EIS) under the National Environmental Protection Act (NEPA)
to analyze the impacts of oil drilling and to consider alternatives to
drilling, such as purchasing private mineral rights; and
The
National Park Service initiates formal consultation with the U.S. Fish
and Wildlife Service on impacts from oil drilling on endangered species
and their critical habitats, such as the Florida panther, Florida
bonneted bat, and the Everglade snail kite.
Further, the Florida
Department of Environmental Protection should not authorize additional
wetland impacts or oil drilling in Big Cypress, particularly in light of
the damage Burnett Oil Company caused during its first exploratory
phase. After all, state and federal agencies are already spending
billions of dollars to restore the Everglades and Big Cypress provides
over 40 percent of water to Everglades National Park. So, is it wise to
industrialize this region to accommodate more oil extraction?
The
Florida Department of Agriculture and Consumer Services’ Secretary,
Nikki Fried, who is a member of Florida Governor DeSantis’ cabinet,
opposes oil drilling in Big Cypress. It is unclear why the Florida
Department of Environmental Protection would permit new drilling in Big
Cypress in light of Governor DeSantis’ prior efforts to protect other
parts of the Everglades from oil development.
New oil development
will jeopardize Floridians way of life and tourism dollars—adverse
impacts could include truck traffic, pipelines and compressor stations,
risks of leaks and spills and related surface and ground water
contamination, air emissions and related impacts to human health and the
climate, noise, lighting, compromised viewsheds, and impacts to
cultural and natural resources and wildlife habitats.
We need state and federal agencies to help preserve what’s left of Florida’s paradise.

Mineral Holdings & Oil Fields
http://www.collierresources.com/mineral-holdings-oil-fields
Collier
Resources Company (CRC) manages more than 800,000 acres of minerals
throughout Collier, Lee and Hendry Counties, leasing mineral rights and
monitoring oil exploration, development and production at three oil
fields – Raccoon Point, Bear Island and Sunniland Field. CRC is also
actively engaged in further exploring its mineral assets.
Sunniland
Field
When
oil was needed to power the war effort during World War II, the federal
government created incentives to locate and drill for oil in Florida.
Humble Oil Company, known today as ExxonMobil, made the first discovery
on Collier minerals at Sunniland Field just south of Immokalee in 1943.
It was the beginning of oil exploration and development in Florida, and
since that time, the Sunniland Field has produced more than 13 million
barrels of oil and continues to produce oil today.
Bear
Island
Partially
located in the Big Cypress National Preserve, oil was discovered in
Bear Island in 1972, prior to the establishment of the preserve, and
production began just a year later. This oil field has yielded nearly 13
million barrels of oil since then and continues to produce oil today.
Raccoon
Point
Oil
at Raccoon Point field was first discovered by ExxonMobil in 1978 and
production began in 1981. The field is located in the Big Cypress
National Preserve near the Collier-Dade County line and produces
approximately 1,950 barrels of oil per day. The field has produced more
than 18 million barrels of oil to date, with a recent increase in
production with the addition of a new horizontal well. The field was
expanded in 1992 as a result of a 3-D seismic survey.

Injection Wells Used to Dispose of Hazardous Waste in Florida
August 04, 2019
Hazardous Waste and Injection Wells
Hazardous
waste is a significant source of water pollution, including dangerous
chemicals harmful to people and the environment. Hazardous materials may
cause severe health and safety problems if not handled correctly. Waste
sources include dangerous byproduct materials generated by factories,
farms, and construction sites. According to a report released on March
29, 2018, by the Environment Florida Research and Policy Center,
industrial facilities dumped 270 times the allowed amount into Florida's
waters. The tenth-worst total in the nation.
According to the
Florida Department of Protection, over 2,100 permitted industrial
wastewater facilities are in Florida. Many industrial facilities use
freshwater to carry away waste into waterways. Wastewater is water that
has been harmfully affected by outside influence and flows from an open
drain. For instance, power plants are near bodies of water and discharge
a significant level of metals such as lead, mercury, cadmium, arsenic,
and chromium into the water. Typical industrial waste could include PCE
(perchloroethylene or tetrachloroethylene), asbestos, lead, mercury,
nitrates, phosphates, sulfur, oils, and petrochemicals. This water ends
up in an environment much more harmful to humans than irrigation water.
Since
the 1960s, deep injection wells (DJW) have been used to protect the
aquifer in Florida. The injection wells dispose of hazardous liquid by
injecting it underground. These wells use a high-pressure pump to force
toxic waste down a pipeline into the deep earth. However, waste fluids
can migrate to the surface through abandoned groundwater wells.
Injection wells are an invisible dumping ground for polluters. Florida
has minimal enforcement and weak protections when it comes to hazardous
waste. Polluters are not being held accountable for dumping chemicals
that threaten our health and environment.

Deepest Well Project In Florida History
February 13, 2015
MIAMI (CBSMiami) – Imagine a 10,000-foot deep injection. Queasy yet?
Don't worry, that's not the next painful vaccine shot. Instead, that's the depth the Miami-Dade Water and Sewer Department (WASD) is going for the state's record well project.
"WASD has recently begun drilling the largest deep injection well in the State of Florida, possibly the country for a water resource purpose at our Central District Waste Water Treatment Plant (CDWWTP)," said WASD Director Lester Sola. "We will be drilling to a depth of 10,000 feet and as a result needed a special drill to be built to accommodate this project."
The purpose of the deep injection well is to comply with future state laws that will prohibit the disposal of treated wastewater into the ocean by 2025. The new disposal method at CDWWTP has already been successfully implemented at the South District Waste Water Treatment Plant.

______________
Improperly Constructed Wells
Several problems associated with improperly constructed wells can result in groundwater contamination from the introduction of contaminated surface or groundwater. Types of wells that are a source of potential groundwater contamination include:
Sumps and dry wells, which collect stormwater runoff and spilled liquids and are used for disposal. These wells sometimes contain contaminants such as used oil and antifreeze that may discharge into water supply areas.
Drainage wells, which are used in wet areas to remove some of the water and transport it to deeper soils. These wells may contain agricultural chemicals and bacteria (U.S. EPA, 1990a).
Injection wells, which are commonly used to dispose of hazardous and non-hazardous industrial wastes. These wells can range from a depth of several hundred to several thousand feet. If properly designed and used, these wells can effectively dispose of wastes. But undesirable wastes can be introduced into groundwater from injection wells when the well is located directly in an aquifer, or if leakage of contaminants occurs from the well head or casing or through fractures in the surrounding rock formations (U.S. EPA, 1990a).
Improperly abandoned wells act as a conduit through which contaminants can reach an aquifer if the well casing has been removed, as is often done, or if the casing is corroded. In addition, some people use abandoned wells to dispose of wastes such as used motor oil. These wells may reach into an aquifer that serves drinking water supply wells. Abandoned exploratory wells (e.g., for gas, oil, coal) or test hole wells are usually uncovered and are a potential conduit for contaminants.
Active drinking water supply wells that are poorly constructed can result in groundwater contamination. Construction problems, such as faulty casings, inadequate covers or lack of concrete pads, allow outside water and any accompanying contaminants to flow into the well. Sources of such contamination can be surface runoff or wastes from farm animals or septic systems. Contaminated fill packed around a well can also degrade well water quality. Well construction problems are more likely to occur in older wells that were in place prior to the establishment of well construction standards and in domestic and livestock wells.
Poorly constructed irrigation wells also can allow contaminants to enter groundwater. Often pesticides and fertilizers are applied in the immediate vicinity of wells on agricultural land.

Restoration Successes in America’s Everglades
August 24, 2023
A River of Grass:
America’s Everglades is called the “river of grass” for a reason. The slow-moving, rain-fed sheet of water that is the Everglades once covered roughly 11,000 square miles, with source waters stemming from the Kissimmee Chain of Lakes and flowing into Lake Okeechobee in the center of the state. From Lake Okeechobee, water historically flowed slowly south through what is now Everglades National Park and into Florida Bay and the Florida Keys, as well as to estuaries on the east and west coasts.
This created a unique patchwork of mangrove forests, sawgrass meadows, estuaries, continuous seagrass meadows, and some of the oldest cypress trees in the world. In fact, it is the only place in the world where the American alligator and crocodile coexist in the wild.
Toxic blue-green algae coats the waters of a canal off Florida’s
Caloosahatchee River. In 2016, harmful algae put St. Lucie and Martin
counties under a 242-day state of emergency.

Everglades
The Everglades is a natural region of flooded grasslands in the southern portion of the U.S. state of Florida, comprising the southern half of a large drainage basin within the Neotropical realm. The system begins near Orlando with the Kissimmee River, which discharges into the vast but shallow Lake Okeechobee. Water leaving the lake in the wet season forms a slow-moving river 60 miles (97 km) wide and over 100 miles (160 km) long, flowing southward across a limestone shelf to Florida Bay at the southern end of the state. The Everglades experiences a wide range of weather patterns, from frequent flooding in the wet season to drought in the dry season. Throughout the 20th century, the Everglades suffered significant loss of habitat and environmental degradation...

How NASA spotted El Niño changing the saltiness of coastal waters

______________
How Are the Saline Glades Changing?
Changes
in plant communities in the park are not limited to Cape Sable.
Paralleling the shoreline in extreme southeastern Florida is a clearly
distinct vegetation community known locally as the saline glades, a
long, linear zone of sparsely vegetated marsh, much of which occurs
within Everglades National Park. Because this area receives little
freshwater flow and lies just out of reach of the tides, it is
unfavorable to the growth of most inland and coastal plant species8. The
zone is best characterized by the few plants species that can survive
there: stunted red mangroves, sawgrass, and spike rush.
Over the
past 50 years, the coastal vegetation of red mangroves has expanded its
range inland (more than 1 km in some areas) and has displaced other
freshwater species8. The red mangroves are able to grow farther inland
because the exchange of fresh and saline water in the marsh has been
influenced by roads, canals, and sea-level rise. Roads block the flow of
fresh water from the north into the saline glades and canals reroute
fresh water away from the area8. Storm surge and overwash from extreme
high tides deposit salt into the soils, making the area inhospitable to
freshwater species, and rising seas have helped extend this reach
farther inland. This increasingly salty environment makes it easier for
saline species to grow and reduces the overall area of freshwater
marsh8. Increased sea levels have also brought similar changes elsewhere
in south Florida.
https://www.nps.gov/ever/learn/nature/cceffectssalineglades.htm
______________
What's Happening to Cape Sable?
One
of the most drastic landscape changes in Everglades National Park, and
one that is complicated by sea-level rise and inland effects, is seen in
the Cape Sable area. Cape Sable is a large coastal landmass located at
the southwestern tip of Florida that was once characterized by an
expansive interior freshwater marsh with associated freshwater lakes. In
the early 1900s, settlers determined to use the area for agriculture
began draining the freshwater out to the ocean so the land could dry7.
However, the canals they built -- coupled with the effects of hurricanes
and the manipulation of water farther north -- transformed Cape Sable,
and much of this alteration has been aggravated by climate change.
Scientists
have used geological clues found in the landscape to estimate historic
sea levels long before humans had the instruments to do so. This
analysis shows that sea-level rise in south Florida was relatively slow
over the past 3,200 years7; however, modern instrumentation has recorded
an accelerated rate of rise over the past century, which has had
visible impacts on Cape Sable. The canals are now a pathway for salty
ocean water and sediments to travel inland, especially during high tides
or with the help of strong wind and surge from tropical storms7. In
recent years, the interior freshwater marsh has disappeared almost
entirely, and nearby lakes have filled almost completely with marine
sediments. Changes along Cape Sable also have implications for the
mangrove trees that live at the waters edge. In response to rising seas
and increased flooding, the trees have been moving inland as the habitat
becomes more suitable. And along the coast, high tides and storm surges
have helped wash sediments away from their roots and have contributed
to erosion along Cape Sable7. While many wonder whether coastal plants
and mangrove forests will be able to keep pace with sea-level rise,
others are beginning to notice similar changes further inland.

27 December 2022
A
fungus, called Metarhizium robertsii, is reportedly able to remove
mercury around plant roots, thus preventing its uptake. The remediation
operation, moreover, occurs as much in the soil as in fresh or salt
water. These findings come from a study published in recent weeks in the
journal Proceedings of the National Academy of Sciences (PNAS).

Growth response and mycoremediation of heavy metals by fungus Pleurotus sp.
19 November 2022
Abstract
Heavy metal contamination (HMs) in water and soil is the most serious
problem caused by industrial and mining processes and other human
activities. Mycoremediation is a biotechnology that employs fungi to
remove toxic contaminants from the environment in an efficient and
cost-effective manner. Pleurotus spp. have been shown to
either increase plant growth on metal-contaminated soils by providing
more nutrients or by reducing metal toxicity. Pleurotus species (J. Lange), a mushroom that can be eaten, has been observed growing on plantations of wood trees in Kerman's orchards. P. sp.
was the subject of this study, which examined the effects of different
concentrations of various heavy metals Cobalt (Co), Copper (Cu), and
Nickel (Ni) (0, 15, 30, 45, and 60 mg/L) on fungal colony diameters,
mycelial dry weights, accumulation of heavy metals, and antioxidative
enzymes. The findings revealed that P. sp. was more
tolerant of Co than other metals, so the fungus grew more in the
presence of low concentrations of Co and Cu. However, even at
concentrations as low as 15 mg/L, Ni greatly inhibited the growth of
biomass and colony diameter. Heavy metals increased the activity of
superoxide dismutases (SOD) and catalase (CAT) up to 45 mg/L, but an
increase in metal concentration above 45 mg/L resulted in a significant
decrease in SOD. Metals in mycelium also increased as the concentrations
of these heavy metals increased.

NASA Study Maps the Roots of Global Mangrove Loss
Sep 29, 2023
Using high-resolution data from the joint NASA-U.S. Geological Survey Landsat program, researchers have created the first map of the causes of change in global mangrove habitats between 2000 and 2016 – a valuable tool to aid conservation efforts for these vital coastline defenders.
Mangroves are hardy trees and shrubs that grow in the salty, wet, muddy soils of Earth’s tropical and subtropical coastlines. They protect the coastlines from erosion and storm damage; store carbon within their roots, trunks, and in the soil; and provide habitats for commercially important marine species. The study showed that overall, mangrove habitat loss declined during the period. However, losses from natural causes like erosion and extreme weather declined more slowly than human causes such as farming and aquaculture. For conservation and resource managers trying to prevent loss or re-establish new habitats, this finding highlights the need for strategies that account for natural causes of loss.
The global map will benefit researchers investigating the carbon cycle impacts of mangrove gain and loss, as well as help conservation organizations identify where to protect or restore these vital coastal habitats.
In 2002, the Río Cauto Delta, pictured here in a January 2020 Landsat 8 image, was named a Ramsar site – an internationally recognized wetland of importance. The delta is home to numerous species of mangroves.
This map shows the location and severity of mangrove habitat loss,
measured in kilometers, caused by natural and human drivers from 2000 to
2016. Darker areas experienced more loss in the period.

Tell Me About: Threats to Mangroves in Florida
Jun 2, 2022
What’s going on?
Although currently protected by Florida law, mangrove deforestation continues due to coastal and urban development. Since the 1900s, vital estuary habitats such as the Tampa Bay and Charlotte Harbor have lost 50-60% of their mangrove forests. Other environmental issues, including climate change and water pollution, also threaten mangroves by changing the distribution and chemistry of their environment. This may include increased storm events and sea-level rise.
Why it matters.
Mangrove forests provide critical habitats for crustaceans, birds, and fish, including many endangered species. They are home to several important species for commercial and recreational fishing industries, a significant part of Florida’s economy. Mangroves remove and store much more carbon per acre than terrestrial forests, making these ecosystems a significant player in fighting climate change.
Found right along the water’s edge, mangroves stabilize shorelines and reduce coastal erosion. They help prevent storm surges and damage to coastal properties during hurricanes and other storm events. Mangroves also improve water clarity and quality by trapping sediments and absorbing nutrients that would obscure or pollute the water.

Florida is in the midst of a still-unfolding water pollution catastrophe. Many formerly picture-perfect beaches and posh waterfront neighborhoods are now surreal toxic landscapes where the smell is so pungent, it can make you nauseous.
Parts of South Florida are being inundated by harmful algal blooms, which affect both public health and marine life, including red tide (caused by the alga Karenia brevis) and blue-green algae (more precisely known as cyanobacteria, or Microcystis, which are technically bacteria but commonly referred to as algae).

Habitat destruction
Human activity has impacted the mangrove ecoregion in Florida. While the coverage of mangroves at the end of the 20th century is estimated to have decreased only 5% from a century earlier, some localities have seen severe reductions. The Lake Worth Lagoon lost 87% of its mangroves in the second half of the 20th century, leaving a remnant of just 276 acres (1.12 km2). Tampa Bay, home to the busy Port of Tampa, lost over 44% of its wetlands, including mangroves and salt marshes, during the 20th century. Three-quarters of the wetlands along the Indian River Lagoon, including mangroves, were impounded for mosquito control during the 20th century. As of 2001, natural water flow was being restored to some of the wetlands.

Improving Water Quality with Mangroves
July 15, 2019
https://www.monitorwater.org/post/improving-water-quality-with-mangroves
In the heart of South Florida, mangrove forests are characteristic of coastline scenery. While many people may not even think twice when passing these ecosystems while biking down a beach road or kayaking atop glassy waters, mangroves hold incredible environmental value, a value that is being threatened by human activity around the world today.By some estimates, more than 50 percent of the world's mangrove forests were destroyed by the end of the 20th century, and half of those that remain are in poor condition. Mangrove forests are among the most threatened habitats in the world, and the loss of mangroves is rampant across the globe.In South Florida, we have an estimated 469,000 acres of mangrove forests that contribute to the overall health of the state's coastal zone. From securing and protecting coastlines, to serving as homes for hundreds of marine and land species, to capturing tons of carbon dioxide from the atmosphere with their immense carbon-storing abilities, mangroves and mangrove forests are key environmental beauties.Mangroves also have the lesser-known, incredible ability to improve the water quality of their ecosystem. Their roots hold onto sediments which reduces erosion and leads to better water quality. They can also absorb nutrients from runoff that could potentially cause harmful algal blooms offshore, an increasingly big problem here in South Florida. Amazingly, both coral reefs and seagrass beds are reliant on the water purifying ability of nearby mangrove forests to keep the water clear and healthy.However, despite their known environmental benefits and impact, mangroves still face the imminent threat of destruction from human action around the world. Human greed continues to devastate mangrove ecosystems, and if we do not stop our current courses of action now, mangroves as we know them may become extinct. From damage from plastic and agricultural pollution to being cleared for coastal development, mangroves continue to be destroyed at an alarming rate, and it is up to us to change this.

Reproductive toxins and alligator abnormalities at Lake Apopka, Florida
1997
Abstract
The alligator population at Lake Apopka in central Florida declined dramatically between 1980 and 1987. Endocrine-disrupting chemicals and specifically DDT metabolites have been implicated in the alligators' reproductive failure. The DDT metabolite hypothesis is based largely on the observation of elevated concentrations of p,p-DDE and p,p-DDD in alligator eggs obtained from Lake Apopka in 1984 and 1985. In the following commentary, we draw attention to two nematocides that are established reproductive toxins in humans, dibromochloropropane (DBCP) and ethylene dibromide (EDB), which could also have played a role in the reproductive failure observed in alligators from Lake Apopka in the early 1980s.

Habitat Loss
Habitat destruction is the issue most often cited for the problems now facing Florida wildlife. Wildlife habitat has declined and even disappeared during the past 100 years as natural lands were converted to agriculture, range lands, and expanding urban areas. During the mid-20th century, Florida lost more than seven million acres of forest and herbaceous wetlands to development. In recent decades, Florida’s massive population growth and booming tourism industry have disturbed and fragmented many natural areas across the state. Estimates based on current growth rates suggest Florida could lose an additional seven million acres of rural and natural lands to urban uses within the next 50 years.

Florida Deforestation Crisis
Florida Deforestation Crisis. Deforestation. The word comes up all the time in conversations about climate change and environmental impact , but how much do most of us really know about deforestation and its true effect? National Geographic defines deforestation as “the purposeful clearing of forested land” (1). Countless forests have been cut down to make room for civilization or to provide wood for manufacturing or building. Deforestation is one of the most obvious forms of environmental damage; we see it every day on the way to work in a casual glance at the many construction sites constantly appearing in new locations. Who even thinks twice when they see a newly-developed neighborhood, a construction area spotted with dirt heaps and tractors, or yet another road work crew on the job? Construction is a part of everyday experience, and because of this, we don’t always make the connection between destructive environmental degradation and that new neighborhood down the street. But they’re inextricably linked, and it’s time to start paying attention.
The Whole Picture
Key to any discussion of deforestation is a full understanding of the term ecosystem. Briefly put, an ecosystem is a “community of coexisting species together with the nonliving parts of their habitat” (2). Fundamental to every ecosystem is the presence of all the necessary components; animals, trees, plants, microorganisms, and water systems all work together to sustain healthy life. Take away one piece of the ecosystem and the entire setup falters. Florida is a notable global hotspot for biodiversity, full of vivid and healthy ecosystems that sustain all different species of animals and plants. But take away the trees and waterways – replace them with roadways and cities – and all of that changes.
One clue to Florida’s amazing biodiversity lies in its multiple climate zones. The U.S. is home to 11 different climate zones, designated by temperature ranges that allow the growth of different plant types (3). Florida in particular among the states is special because it contains the warmer zones 8-10, making it one of the only locations conducive to growing both tropical and subtropical plants. Wetlands are also a major part of the Florida landscape, and these damp, swampy areas provide a home to countless species and perform several other essential but often-ignored functions. Coastal wetlands act as a filter, removing excess pollutants and nutrients from water and preventing coastal erosion (4). However, human activities are severely damaging Florida wetlands, destroying these diversely inhabited wildlife homes and subjecting the landscape as a whole to unprecedented change.
Historic South Florida water flow vs. current water flow
Florida’s history includes the mentality of “draining the swamp”, which was a term associated with destroying wetlands to increase the areas in Florida available for construction. This mindset along with the “Florida is a blank canvas” ethos collectively normalized the destruction of the natural Florida landscape for the benefit of the real estate / tourism market. Little did these developers understand just how important the hydrology systems of wetlands are to our water system (5).
Florida’s red tides are partly a result of the expansive wetland loss, as these wetland ecosystems are no longer able to filter nutrient-filled liquid before it reaches larger bodies of water (6). Construction is systematically disturbing the balance of Florida’s expansive statewide ecosystem and contributing to such a major source of pollution.
Deforestation and Florida’s Trees
The unique Florida climate provides for a number of different forest habitats. Florida’s upland ecosystems, predominated by hardwood pine forests, scrub, etc. are home to many tree species (7). These habitats include: Pine Flatwoods, Oak Scrub, Coastal Strands, Coastal Scrub, Hammocks, Cypress Swamps, and more. Here is a short breakdown of some common Florida habitats and the important trees that call these places home...

Selective radio frequency pest control apparatus
1995
Abstract
This
application discloses an apparatus and method for generating and
radiating energy at specific radio frequency wavelengths known to
adversely affect the nervous systems of small insects such as flies,
gnats, cockroaches, termites and the like wherein each is affected by a
different frequency or range of frequencies; the apparatus containing a
power supply, a voltage selector circuit for generating sequences of
specific voltages, a modulator circuit to amplitude modulate each
specific voltage about its center level, a multiple frequency generator
to convert each modulated voltage into a modulated frequency of both
fundamental and harmonic content, a radio frequency transmitter circuit,
and a random interval timer circuit to energize and de-energize the
radio frequency transmitter circuit in such a manner as to prevent the
pest from acquiring an immunity to the radiated energy. There is further
disclosed a method of forming patterns of radiated energy wherein said
multiple frequency generator, said modulator circuit, said voltage
selector circuit, said radio frequency transmitter circuit and said
random interval timer circuit are operably connected in such a manner as
to produce bursts of radio frequency energy at slightly varying fixed
frequencies having both fundamental and harmonic content and wherein
such bursts are continuously varied in both their interval and duration.

Exposure of Insects to Radio-Frequency Electromagnetic Fields from 2 to 120 GHz
02 March 2018
Abstract
Insects
are continually exposed to Radio-Frequency (RF) electromagnetic fields
at different frequencies. The range of frequencies used for wireless
telecommunication systems will increase in the near future from below
6 GHz (2 G, 3 G, 4 G, and WiFi) to frequencies up to 120 GHz (5 G). This
paper is the first to report the absorbed RF electromagnetic power in
four different types of insects as a function of frequency from 2 GHz to
120 GHz. A set of insect models was obtained using novel Micro-CT
(computer tomography) imaging. These models were used for the first time
in finite-difference time-domain electromagnetic simulations. All
insects showed a dependence of the absorbed power on the frequency. All
insects showed a general increase in absorbed RF power at and above
6 GHz, in comparison to the absorbed RF power below 6 GHz. Our
simulations showed that a shift of 10% of the incident power density to
frequencies above 6 GHz would lead to an increase in absorbed power
between 3–370%.

pesticides can mitigate their impact, causing severe health and
environmental issues. Hence, innovative eco-friendly and low-cost
solutions must be promoted apart from chemical control. Here, we have
investigated the use of laser radiation as a reliable solution. We have
analyzed the lethal dose required to kill 90% of a population for two
major pest aphid species (Acyrthosiphon pisum and Rhopalosiphum padi).
We showed that irradiating insects at an early stage (one-day old nymph)
is crucial to lower the lethal dose without affecting plant growth and
health. The laser is mostly lethal, but it can also cause insect
stunting and a reduction of survivors’ fecundity. Nevertheless, we did
not notice any significant visible effect on the offspring of the
surviving irradiated generation. The estimated energy cost and the
harmless effect of laser radiation on host plants show that this
physics-based strategy can be a promising alternative to chemical
pesticides.

Photonic molecule
Photonic molecules are a form of matter in which photons bind together to form "molecules".[1][2][3] They were first predicted in 2007. Photonic molecules are formed when individual (massless) photons "interact with each other so strongly that they act as though they have mass".[4] In an alternative definition (which is not equivalent), photons confined to two or more coupled optical cavities also reproduce the physics of interacting atomic energy levels, and have been termed as photonic molecules.
Researchers drew analogies between the phenomenon and the fictional "lightsaber" from Star Wars.

Detection of pesticides using nanozymes: Trends, challenges and outlook
Abstract
Effective
monitoring of pesticide residues in food and environmental samples is
of high importance as these chemical residues undergo ongoing eco- and
bio-accumulation, compromising the health of humans and animals alike.
Several sensor platforms are being developed for the detection of
pesticide residues in a range of sample matrices. A relatively new
sensor platform that has gained enormous attention is based on the
natural enzyme-mimicking catalytic activity of nanomaterials, more
commonly referred to as nanozyme activity. In this review, we provide a
critical overview of the recent advances in nanozyme-based sensing
strategies for the detection of pesticides. The review highlights the
salient features and the working principle of various nanozyme-based
sensors, their integration with molecular recognition elements (MREs) to
improve target specificity, and associated limitations that must be
overcome to turn nanozyme sensors into mainstream analytical tools. The
review further provides a critical outlook of nanozyme-based sensors for
pesticide detection. The last section of the review outlines the steps
that must be taken to realise the full potential of nanozyme-based
sensors.

Digital holography
https://en.wikipedia.org/wiki/Digital_holography
Phase-shifting holography
The
phase-shifting (or phase-stepped) digital holography process entails
capturing multiple interferograms that each indicate the optical phase
relationships between light returned from all points on the illuminated
object and a controlled reference beam of light. The optical phase of
the reference beam is shifted from one sampled interferogram to the
next. From a linear combination of these interferograms, complex-valued
holograms are formed. These holograms contain amplitude and phase
information of the optical radiation diffracted by the object, in the
sensor plane.
Frequency-shifting holography
Through the
use of electro-optic modulators (Pockel cells) or acousto-optic
modulators (Bragg cells), the reference laser beam can be
frequency-shifted by a tunable quantity. This enables optical heterodyne
detection, a frequency-conversion process aimed at shifting a given
radiofrequency optical signal component in the sensor's temporal
bandwidth. Frequency-shifted holograms can be used for narrowband laser
Doppler imaging.

Quasi-crystalline order in vibrating granular matter
19 January 2024
Abstract
Quasi-crystals
are aperiodic structures with crystallographic properties that are not
compatible with that of a single unit cell. Their discovery in a
metallic alloy more than four decades ago has required a full
reconsideration of our definition of a crystal structure.
Quasi-crystalline structures have also been discovered at much larger
length scales in different microscopic systems for which the size of the
elementary building blocks ranges from the nanometre to the micrometre
scale. Here we report the first experimental observation of spontaneous
quasi-crystalline self-assembly at the millimetre scale. This result is
obtained in a fully athermal system of macroscopic spherical grains
vibrating on a substrate. Starting from a liquid-like disordered phase,
the grains begin to locally arrange into three types of square and
triangle tile that eventually align, forming an eight-fold symmetric
quasi-crystal that has been predicted in simulation but not yet
experimentally observed in non-atomic systems. These results not only
demonstrate an alternative route for the spontaneous assembly of
quasi-crystals but are of fundamental interest for the connection
between equilibrium and non-equilibrium statistical physics.

Nanoparticle quasicrystal constructed with DNA
November 2, 2023
ANN
ARBOR—Nanoengineers have created a quasicrystal—a scientifically
intriguing and technologically promising material structure—from
nanoparticles using DNA, the molecule that encodes life.
The
team, led by researchers at Northwestern University, the University of
Michigan and the Center for Cooperative Research in Biomaterials in San
Sebastian, Spain, reports the results in Nature Materials.
Unlike
ordinary crystals, which are defined by a repeating structure, the
patterns in quasicrystals don’t repeat. Quasicrystals built from atoms
can have exceptional properties—for example, absorbing heat and light
differently, exhibiting unusual electronic properties such as conducting
electricity without resistance, or their surfaces are very hard or very
slippery.
Engineers studying nanoscale assembly often view
nanoparticles as a kind of ‘designer atom,’ which provides a new level
of control over synthetic materials. One of the challenges is directing
particles to assemble into desired structures with useful qualities, and
in building this first DNA-assembled quasicrystal, the team entered a
new frontier in nanomaterial design...
A mathematical tool called a fast Fourier transform maps the structure
in a way that reveals the 12-fold symmetry of the quasicrystal. The fast
Fourier transform of the electron microscope image of the quasicrystal
is shown on the left, while the transform of the simulated crystal is
shown on the right.

Sound research
Scientific innovations harness noise and acoustics for healing
Bioengineering | Spring 2018
From
the original stethoscope, invented more than 200 years ago, to the
fleeting chirp of gravitational waves, sound has reverberated throughout
the history of technological and scientific advances.
Today, the
role of sound in science extends beyond the range of audible
frequencies: Ultrasonic and other silent acoustic waves have made their
way into researchers’ repertoire, helping them push the boundaries of
conventional medicine and research.
In examples from four
Stanford labs, scientists are investigating the full spectrum,
harnessing the nuances of noise and the power of acoustics to generate
inventive, if not unexpected, technologies that show just how potent the
combination of sound and science can be.
Turning the irksome into the advantage
Nothing
incites irritation in quite the same way as a lurking mosquito. But its
high-pitched drone may actually help curb spikes in mosquito
populations and, more importantly, the diseases that they pass on to
humans. This, at least, is the premise behind Manu Prakash’s newly

HAARP AND NEW TECHNOLOGIES THAT AFFECT HUMAN BEHAVIOUR
2001
http://www.consumerhealth.org/articles/display_ID_20011005223152.html
WHAT IS HAARP?
HAARP
stands for High-frequency Active Auroral Research Project. HAARP is a
joint project by the U.S. Navy and Air Force in Alaska to create a very
large radio frequency transmitter which can transmit an electromagnetic
beam into the upper atmosphere or ionosphere. This radio-frequency
energy is broadcast through a field of 48 antennas which are 72 feet
tall and they have a cross diapoled across the top. Electromagnetic
waves then bounce back onto Earth and penetrate everything--living and
dead. Normally, radio frequency energy dissipates with distance, but by
firing them in a unique way, the energy is focussed and a cyclotron
resonance effect occurs. This produces very much more concentrated and
potent energy when it delivers its load either through magnetic lines of
force or to the ionosphere. The cyclotron resonance energy wraps itself
around these magnetic lines and it moves north to south. This was
intended to create a shielding effect during a nuclear attack. The ideal
place to locate these instruments happens to be in the northern regions
where the magnetic lines of force intersect the planet, and the
research project was located in Alaska.
EXTREMELY LOW FREQUENCY (ELF) RADIATION
When
HAARP sends up a signal in the high frequency range and they begin to
pulse or vibrate that signal, the ionosphere itself converts from DC to
AC, begins to mirror the pulse rate and acts like a giant broadcast
antenna in the sky, perhaps as much as a 1,000 miles above this
transmitter. It pulses the signal back to the earth in the extremely low
frequency (ELF) range. This is between one and approximately 100 Hertz.
That is what is used for communication with submarines at depth using
14 and 26 mile long antennas buried underground in Michigan, Wisconsin
and in Alaska to create that signal. With HAARP, they thought they would
have a little more versatility and the ability to communicate at higher
data rates and more efficiently with submarines at depth. It is the
same ELF that is used for earth penetrating tomography because you need a
long wave in order to penetrate the earth to any great degree. Short
wavelengths just don't go very far. The problem is, earth penetrating
tomography operates in the ELF range, which happens to correlate to
biologically active frequencies in the human body, particularly in the
human brain.
FREQUENCY RANGES IN THE HUMAN BRAIN
The
human brain predominantly operates on a frequency of between one and 30
pulses per second, cycles per second Hertz, and it varies. One to four
pulses per second is the delta range. This is where you are in your
deepest, deepest sleep. The next level is theta, which is about 4 to 7
cycles per second. This is the range where you are in that semi-awake,
semi-asleep stage where you are sort of drifting off. You are aware of
your dreams but are aware you are awake. This is where most three to
five-year-olds spend most of their lives, which explains an awful lot.
But it is also where they learn a tremendous amount. This is where they
learn language, social skills, everything that kids learn between the
ages of three and five. This is also the state where a lot of people
re-experience childhood events, because that is where you are when you
are a child. The next stage is the alpha stage, which goes from about 7
to 12 Hertz. This is where you are when you do your most creative and
intellectual work. It is interesting to note that the planet Earth
pulses at Schumann's Resonance which is 7.83 Hertz. That is the ideal
frequency for human beings to be engaged in, and we are separated from
that because we are surrounded by Tesla's invention of 60 cycles of AC
current which is agitating to most of our systems. The next level is
beta. Low beta is where we are actively engaged in learning and thinking
and dialogue. You are in high beta when you get agitated and angry,
when you have high, strong emotions.
EFFECTS OF ELF ON THE BRAIN
The
problem is that external signals like the radio frequency signals of
HAARP, and any electromagnetic signals from light and sound waves that
can be pulsed in this ELF range will cause the brain to begin to lock
onto that external signal and begin to mirror it. When it does so, it
changes the character and chemistry of the brain during that period of
time and your behaviour changes. Early researchers have claimed that
these ELF concentrations of energy are harmless, but over the last 20
years, researchers have recognized that very low energy concentrations
can have profound physiological effects. The military rationalizes that
HAARP instruments broadcast the signal in the ELF range and this is a
very, very low level of electromagnetic radiation by the time it gets
back to the earth, that it is nothing to worry about, that it is about
equal to what the earth naturally produces. They compare it to things
like the flickering of the television set.
ZAPPING THE BODY WITH ELF
However,
Jose Delgado at Yale University researched radio frequency energy, and
discovered that he could influence the brain using a pulsed radio
frequency signal concentration at one-fiftieth of the energy that the
earth naturally produces, and this was sufficient to change the
behaviour of primates and humans like flipping on and off a light
switch. It was not the magnitude of energy, but its specific frequency
which triggered events within the brain, changed brain chemistry and
consequently changed behaviour. A few years ago, a story was released
about children having epileptic seizures from watching a cartoon on
television. A reaction in the brain was caused by the flicker rate
hitting one of these frequencies inadvertently. It wasn't the amount of
energy; it was the frequency. It is like dialing a radio station. In
between stations, you hear static. When you hit a resonant frequency, a
signal that corresponds to the receiver, you get a clear signal.
The
same is true of the human body. Every organ, every chemical, every
element within our body has a unique resonant frequency that can be
measured. In fact, the basic organs of the body have been measured for
radio frequency symmetry by the University of Utah under contract with
the United States Air Force. The study is cited in our books. You can
look it up. They have actually determined the amount of radio frequency
energy each part of the body can tolerate. So if you want to stop a
heart, you know how to do it. This is kind of a gross application of the
technology. A more refined application would be to target a chemical or
chemical compound within the population that is present in all of us,
that is universal. For instance, if you send a signal that resonates at
the same frequency as iodine, you trick the body into thinking it has
been poisoned by iodine. And you have a mystery illness which doesn't
show on tests because the iodine is not there. This can be used in lots
of different ways. If everyone breaths in a substance during war, you
can send energy that amplifies its effect, and you can create some
pretty horrendous special effects.
The idea that HAARP
inadvertently or purposefully might be used in this way is kind of
shocking. In Between Two Ages (p.54-56), Zbigniew Brezinski, previous
National Security Advisor to President Carter, discussed triggering an
event in the ionosphere that could affect human behaviour. Referring to
research out of UCLA by Gordon MacDonald, Brezinski suggested that if
you could electronically stroke the ionosphere in just the right way to
return a signal in the ELF range, you could manipulate the emotions of a
population of a large geographic area. Between Two Ages is about
technology's impact on society, culture and economies, and it gave a
25-year forecast of what was going to happen globally. It was written in
the early '70s, so it reads like a history because it is dead right on.
In Earth Rising: The Revolution, our latest book, we cite a CIA
experiment in which they actually tried this in Eastern Europe. There is
plenty of evidence that the Russians were doing this to us. Remember
the macrowave beaming of the U.S. Embassy? There are reports of Russian
research where they exposed primates to this same signal. This research
is still classified because it caused disruption of physical health.

High-frequency Active Auroral Research Program
https://en.wikipedia.org/wiki/High-frequency_Active_Auroral_Research_Program
The
High-frequency Active Auroral Research Program (HAARP) is a University
of Alaska Fairbanks program which researches the ionosphere – the
highest, ionized part of Earth's atmosphere.
The most prominent
instrument at HAARP is the Ionospheric Research Instrument (IRI), a
high-power radio frequency transmitter facility operating in the high
frequency (HF) band. The IRI is used to temporarily excite a limited
area of the ionosphere. Other instruments, such as a VHF and a UHF
radar, a fluxgate magnetometer, a digisonde (an ionospheric sounding
device), and an induction magnetometer, are used to study the physical
processes that occur in the excited region.
Initially HAARP was
jointly funded by the U.S. Air Force, the U.S. Navy, the University of
Alaska Fairbanks, and the Defense Advanced Research Projects Agency
(DARPA).[1] It was designed and built by BAE Advanced Technologies. Its
original purpose was to analyze the ionosphere and investigate the
potential for developing ionospheric enhancement technology for radio
communications and surveillance.[2] Since 2015 it has been operated by
the University of Alaska Fairbanks.[3]
Work on the HAARP facility
began in 1993. The current working IRI was completed in 2007; its prime
contractor was BAE Systems Advanced Technologies.[1] As of 2008, HAARP
had incurred around $250 million in tax-funded construction and
operating costs. In May 2014, it was announced that the HAARP program
would be permanently shut down later in the year.[4] After discussions
between the parties, ownership of the facility was transferred to the
University of Alaska Fairbanks in August 2015.[5]
HAARP is a
target of conspiracy theorists, who claim that it is capable of weather
manipulation. Commentators and scientists say that advocates of this and
other conspiracy theories are wrong,[6] as claims made fall well
outside the abilities of the facility, if not the scope of natural
science.
Research
HAARP's main goal is basic science
research in the uppermost portion of the atmosphere, termed the
ionosphere. Essentially a transition between the atmosphere and the
magnetosphere, the ionosphere is where the atmosphere is thin enough
that the Sun's X-rays and UV rays can reach it, but thick enough that
there are enough molecules present to absorb those rays. Consequently,
the ionosphere consists of a rapid increase in density of free
electrons, beginning at ~70 km, reaching a peak at ~300 km, and then
falling off again as the atmosphere disappears entirely by ~1,000 km.
Various aspects of HAARP can study all of the main layers of the
ionosphere.
The profile of the ionosphere is highly variable,
changing constantly on timescales of minutes, hours, days, seasons, and
years. This profile becomes even more complex near Earth's magnetic
poles, where the nearly vertical alignment and intensity of Earth's
magnetic field can cause physical effects like the aurora.
The
ionosphere is traditionally very difficult to measure. Balloons cannot
reach it because the air is too thin, but satellites cannot orbit there
because the air is too thick. Hence, most experiments on the ionosphere
give only small pieces of information. HAARP approaches the study of the
ionosphere by following in the footsteps of an ionospheric heater
called EISCAT near Tromsø, Norway. There, scientists pioneered
exploration of the ionosphere by perturbing it with radio waves in the
2–10 MHz range, and studying how the ionosphere reacts. HAARP performs
the same functions but with more power and a more flexible and agile HF
beam.
Some of the main capabilities of HAARP include:
Generating very low frequency (VLF) radio waves by modulated heating of
the auroral electrojet, useful because generating VLF waves ordinarily
requires gigantic antennas
Generating artificial Airglow, which
is typically subvisual but routinely detectable. Under certain
geophysical conditions and transmitter configurations, it can be bright
enough to observe with the unaided eye.[17][18]
Generating
extremely low frequency (ELF) waves in the 0.1 Hz range. These are next
to impossible to produce any other way, because the length of an antenna
is dictated by the wavelength of the signal it emits or receives.
Generating whistler-mode VLF signals that enter the magnetosphere and
propagate to the other hemisphere, interacting with Van Allen radiation
belt particles along the way
VLF remote sensing of the heated ionosphere
Research at the HAARP has included:
Plasma line observations
Stimulated electron emission observations
Gyro frequency heating research
Spread F observations (blurring of ionospheric echoes of radio waves
due to irregularities in electron density in the F layer)
High-velocity trace runs
Airglow observations[19]
Heating induced scintillation observations
VLF and ELF generation observations[20]
Radio observations of meteors
Polar mesospheric summer echoes (PMSE) have been studied, probing the
mesosphere using the IRI as a powerful radar, and with a 28 MHz radar
and two VHF radars at 49 MHz and 139 MHz. The presence of multiple
radars spanning both HF and VHF bands allows scientists to make
comparative measurements that may someday lead to an understanding of
the processes that form these elusive phenomena.
Research into extraterrestrial HF radar echos: the Lunar Echo experiment (2008).[21][22]
Testing of spread spectrum Transmitters (2009)
Meteor shower impacts on the ionosphere
Response and recovery of the ionosphere from solar flares and geomagnetic storms
The effect of ionospheric disturbances on GPS satellite signal quality
Producing high density plasma clouds in Earth's upper atmosphere[23]
Research
conducted at the HAARP facility has allowed the US military to perfect
communications with its fleet of submarines by sending radio signals
over long distances.

Why scientists used these radio transmitters to create artificial auroras
Sending radio pulses into the upper atmosphere can create splotches of red and green light.
Nov 10, 2023
If
you live in and around Gulkana, Alaska and recently saw some eerie
lights in the sky—don’t worry; they were all part of a science
experiment. Earlier this week, researchers from the University of Alaska
Fairbanks and several other US institutions created artificial auroras
by sending radio pulses into the Earth’s ionosphere using HAARP (High
Frequency Active Auroral Research Program) transmitters on the ground.
The frequencies of these transmissions were between 2.8 and 10
megahertz.
These transmitters act as heaters that excite the
gasses in the upper atmosphere. When the gasses “de-excite,” they
produce an airglow between 120 and 150 miles above ground, according to a
notice about the project issued by the HAARP team. This is similar to
how charged particles from the sun interact with gasses in the upper
atmosphere to create natural auroras; the charged particles are steered
by the Earth’s magnetic field to the north and south poles to form
aurora borealis and aurora australis. Compared to those light displays,
the artificial auroras are much weaker.

Assessment of carbon dioxide piscicide treatments
January 1, 2018
Few
chemicals are approved to control or eradicate nuisance fish
populations in the United States. Carbon dioxide (CO2) is currently
being developed and studied as a new piscicide option for nonselective
population control. This study evaluated dry ice (solid state CO2) as a
simple CO2 delivery method during winter piscicide applications.
Nonnative Silver Carp Hypophthalmichthys molitrix, Bighead Carp H.
nobilis, and native Fathead Minnow Pimephales promelas were overwintered
together in ice‐covered ponds treated with 25 kg dry ice/100,000 L (low
treatment) or 50 kg dry ice/100,000 L (high treatment). Overwinter fish
survival was significantly reduced in ponds treated with dry ice
relative to untreated control ponds. Fathead Minnows were less
susceptible to CO2exposure than the carps, with 26–96% survival in
low‐treatment ponds and 4–68% survival in high‐treatment ponds. Silver
Carp and Bighead Carp were more sensitive to CO2 treatments and no
individuals of either species survived in ponds with the high‐treatment
level. Water samples were also collected in all ponds throughout this
study, and we observed notably higher Silver Carp and Bighead Carp
environmental DNA (eDNA) concentrations in dry‐ice‐treated ponds
relative to untreated control ponds. Distinct changes in eDNA trends
correlated with fish mortality, and results indicate that eDNA sampling
could be a useful indicator of piscicide efficacy. This study
demonstrates that CO2 administered as dry ice is an effective under‐ice
piscicide method.

Piscicide impact extends beyond targets and toxicity
2018
Abstract
Restoration
of fisheries often requires removal of invasive fishes. Although
piscicides such as antimycin a and rotenone are reliable and
cost-effective tools for such removals, they may reduce the abundance of
nontarget species directly via toxicity-induced mortality (toxic
effect) or indirectly via loss of prey (trophic effect). Toxic effects
are well documented in some taxa, especially in benthic
macroinvertebrates (BMIs). Yet, the corresponding trophic effects on
nonpiscine, aquatic, and riparian species remain unstudied. I tested for
a trophic effect of piscicides using a population of American Dippers
(Cinclus mexicanus), songbirds that feed extensively on BMIs. I caught
breeding birds and estimated body condition before, during, and after
treatment of the stream with antimycin a or rotenone. Birds exhibited
poorer body condition (3.0–3.7% lower body mass) during treatment than
before or after treatment. These differences suggested that treatment
reduced prey availability enough to impact birds at least 9 months after
application. Therefore, continued use of piscicides for fish
restoration would benefit from (1) site-specific comparison of benefits
of invasive fish removal to costs of potential or documented toxic and
trophic effects of piscicides on nontarget organisms; (2) continued
adherence to best practices for recovery of the BMI community after
piscicide treatment; and (3) experimental study of piscicide impacts.

There is significant confusion concerning whether and how this material
may be used in USDA-certified organic farming.
Although the
Organic Materials Review Institute (OMRI) Generic Materials List
identifies rotenone as “Allowed with Restrictions” on organic farms, the
material is only legally allowed under certain conditions. Other
substances commonly used with rotenone, including piperonyl butoxide,
are explicitly prohibited for use in organic agriculture. The National
Organic Program (NOP) is currently exploring possible changes to the
regulations, potentially limiting or prohibiting the use of rotenone.
Rotenone
is commonly derived from the roots of various tropical plants native to
Southeast Asia, South America and East Africa. Historically, farmers
have used this extract as a foliar spray to control pests on vegetables,
berries, tree fruits, nuts, forage crops and sugarcane. It was first
registered in the United States in 1947, and through the years, the
Environmental Protection Agency (EPA) required a number of studies to
further confirm its safety status for use in agriculture. In 2004, the
EPA required an inhalation neurotoxicity study to further investigate
the possibility of rotenone leading to Parkinson’s Disease-like symptoms
at high dose exposure in animals. Instead, the companies distributing
and selling rotenone products voluntarily cancelled all food use
registrations for it, except for piscicide (fish kill) uses. Since
then, the EPA only supports registration for piscicidal purposes.

Addition of Cinnamon Oil Improves Toxicity of Rotenone to Spodoptera litura (Lepidoptera: Noctuidae) Larvae
1 September 2017
Abstract
Although
rotenone is widely used as a pesticide, it has a low level of
insecticidal activity on Spodoptera litura (F.) (Lepidoptera:
Noctuidae). To gain a better understanding of the high tolerance to
rotenone, a synergist (cinnamon oil) was added, and the comparative
physiological impacts were assessed. After rotenone treatment, a
considerable amount of rotenone was discharged in excreta, but extremely
low levels were found in the ventral nerve cord and brain. By contrast,
the rotenone cinnamon oil treatment group showed an increased amount of
rotenone in the ventral nerve cord and brain. The co-toxicity
coefficient for rotenone cinnamon was 213, indicating synergism. The
midgut cells from insects treated with rotenone alone, and the controls,
exhibited no significant differences, whereas those of the rotenone
cinnamon oil group had larger intercellular spaces. These findings
suggest that rotenone alone could not effectively penetrate the midgut,
perhaps accounting for its low toxicity to S. litura. The rotenone
cinnamon oil mixture apparently affected midgut cell spacing and
membrane permeability, thus effectively increasing rotenone toxicity.

Acute Toxicity of 5% Rotenone to Northern Snakeheads
August 2006
Abstract
The
confirmation of northern snakeheads Channa argus caught by an angler in
a private pond in Maryland resulted in significant media attention and
generated numerous resources for risk identification and the development
of action plans to prevent the introduction of this nonnative species
into state waters. Rotenone was selected as an eradication option, and a
bioassay was conducted with captured northern snakehead juveniles to
determine toxicity and application dose. The lowest rotenone
concentration evaluated, 0.075 mg of active ingredient per liter of
water, resulted in 100% mortality within 1 h. Pond treatment was highly
successful; 8 adult and 834 juvenile snakeheads were recovered. Study
results show that northern snakeheads are susceptible to normal doses of
rotenone and that standard pond treatment techniques are effective in
eradicating this invasive species.

Common pesticide may have made the Zika epidemic worse
SEPTEMBER 21, 2021
Before COVID, there was Zika. In 2015, the number of babies born in
Brazil with small heads and brains—a condition known as
microcephaly—suddenly increased dramatically. The severe deformities
left the children disabled for life, and caused intense global concern.
These cases of microcephaly were soon shown to be caused by pregnant women being infected with the mosquito-borne Zika virus. The virus infects and kills cells that form the brain, hampering its proper development.
But the impact was not universal—certain regions in north-eastern Brazil saw far more cases of microcephaly than others.
Scientists began to question whether other factors might be at play that intensified the epidemic in some places. Not long after, they focused their attention on pyriproxyfen, a globally approved pesticide used against household insects in agriculture—including mosquitoes. Pyriproxyfen was used intensively in the regions with the highest numbers of microcephaly cases.
Now, in a new study, we have shown that pyriproxyfen could indeed exacerbate the already severe effects the Zika virus has on fetal brain development...
Genetically modified tadpoles emit green fluorescence when exposed to
thyroid hormone (T3 in the image). When they were simultaneously exposed
to pyriproxyfen, the fluorescent signal dropped significantly, showing
the insecticide blocks thyroid hormone action.

Toxic coal ash is making its way to Florida from Puerto Rico. Experts warn of its adverse health effects
February 7, 2020
The
AES power plant in Puerto Rico generates 300,000 tons of coal ash, the
toxic byproduct of coal burned to generate electricity, each year. The
residents of the island, understandably, don't want to be near the toxic
elements, so they passed a law "to prohibit the deposit and disposal of
coal ashes or coal combustion residues in Puerto Rico."
In addition, the law prevents the ash from being stored on the island for more than 180 days.
So where does the coal ash go? A lot of it — tens of thousands of tons — makes its way to the mainland U.S.
CBS
News tracked one cargo ship, the Mississippi Enterprise, as it was
hauling coal ash into Jacksonville, Florida. From there, the ash is
taken to Chesser Island landfill in Folkston, Georgia, as reported by
local Puerto Rican journalist Abner Dennis and Omar Alfonso.
Lawyer
and activist Ruth Santiago, who has been battling AES to provide better
safeguards in disposing the coal ash, warned communities in Florida and
elsewhere where the ash was being disposed: "They should not allow the
import of the toxic coal ash to their communities."

Newly discovered roundworm species could help limit pesticide use
Feb 26, 2024
RIVERSIDE
— Chemical pesticides have come under a lot of scrutiny lately for
their potential effects on human health and the environment. In fact,
several cities across the country have started taking action to ban the
use of some types.
Now, researchers in California have made an
exciting discovery that's an alternative to chemical pesticides and
could impact earth.
Nematodes are microscopic roundworms that
often get a bad wrap in the agriculture community because some are
dangerous to humans and animals and some kill crops. But there are also
types that target insects.
“These are the good guys. These are
often known as beneficial nematodes,” said Adler Dillman a professor who
studies nematodes at the University of California at Riverside.
They enter insects through their openings like a mouth and then kill them within 48 hours from the inside.
There
are 100 species of these good Steinermnema that researchers around the
world know about and each has unique features that makes it thrive in
different conditions.
Dillman was trying to sequence genomes for
some of these insect-killing nematodes and received a batch from
Thailand for his work. However, when he started running tests, he
discovered that the worms he ordered were not the ones he got.
“It turns out it was a previously undescribed species. It wasn't like anything else that is known,” Dillman said.
The
researchers decided to name the new species Steinornema Adamsi. These
nematodes are completely safe for people and only target insects.
Dillman
and his team are now working to understand the unique characteristics
of this nematode to see if it's better adapted to humidity or a certain
type of soil.
Then, farmers can use that knowledge in their
application. many agriculturists already spray nematodes on their land
rather than pesticides. It is more expensive but the worms
self-replicate and can last multiple planting seasons, so Dillman says
there's enormous potential.
“We have become more conscientious
and aware of the damage, the ecological damage of chemical pesticides
and their health effects, not only on humans, but on the rest of the
environment, contaminating water sources and other things,” Dillman
said. “Our food abundance, food security is a major global problem and
insects cause a significant loss of global crop yield. Being able to use
something that is environmentally friendly and ecologically safe, but
can also significantly reduce insect herbivory of our crops will be
beneficial to everyone.”

Farmers
use $60 billion of pesticides each year. 2 MIT scientists have
developed a new technology that could cut that number in half
Dec. 19, 2022
Kripa
Varanasi had just started his first year as an assistant professor of
mechanical engineering at the Massachusetts Institute of Technology in
2009 when he went to Washington, D.C., to give a talk at the U.S.
Department of Agriculture. His academic focus was on the bottlenecks
that occur between states of matter—where liquids and solids meet, for
example—and he was studying how to make droplets stick to, or bounce
off, solids in various applications. Varanasi had just come off a stint
in industry, at GE, where he was inculcated in the entrepreneur’s habit
of looking for problems to solve, so he asked the USDA representatives
for their top gripe. They didn’t hesitate to answer: “Pesticide runoff
is a big problem.”
Now, 13 years later, Varanasi and one of his
since graduated Ph.D. students—Vishnu Jayaprakash—have launched AgZen,
which uses additives developed in the lab to make more pesticide spray
droplets stick to the plants they hit. In early lab tests and field
trials, the additives replicated farmers’ prior results but with up to
50% less pesticide, cutting costs and reducing pollution from runoff and
wind-carried chemicals.
“Globally, farms are spending about $60
billion a year on these pesticides, and our goal is to try to get them
to cut that down while still not compromising on pest control,” says
Jayaprakash, AgZen’s CEO.
The company, which officially launched
in 2020, has raised $3 million in seed funding (Material Impact is an
investor) and won about $600,000 in prizes such as runner-up awards at
the MIT $100K and Rice Business Plan competitions.

Biopesticides
as a promising alternative to synthetic pesticides: A case for
microbial pesticides, phytopesticides, and nanobiopesticides
2023 Feb 16
Abstract
Over
the years, synthetic pesticides like herbicides, algicides, miticides,
bactericides, fumigants, termiticides, repellents, insecticides,
molluscicides, nematicides, and pheromones have been used to improve
crop yield. When pesticides are used, the over-application and excess
discharge into water bodies during rainfall often lead to death of fish
and other aquatic life. Even when the fishes still live, their
consumption by humans may lead to the biomagnification of chemicals in
the body system and can cause deadly diseases, such as cancer, kidney
diseases, diabetes, liver dysfunction, eczema, neurological destruction,
cardiovascular diseases, and so on. Equally, synthetic pesticides harm
the soil texture, soil microbes, animals, and plants. The dangers
associated with the use of synthetic pesticides have necessitated the
need for alternative use of organic pesticides (biopesticides), which
are cheaper, environment friendly, and sustainable. Biopesticides can be
sourced from microbes (e.g., metabolites), plants (e.g., from their
exudates, essential oil, and extracts from bark, root, and leaves), and
nanoparticles of biological origin (e.g., silver and gold
nanoparticles). Unlike synthetic pesticides, microbial pesticides are
specific in action, can be easily sourced without the need for expensive
chemicals, and are environmentally sustainable without residual
effects. Phytopesticides have myriad of phytochemical compounds that
make them exhibit various mechanisms of action, likewise, they are not
associated with the release of greenhouse gases and are of lesser risks
to human health compared to the available synthetic pesticides.
Nanobiopesticides have higher pesticidal activity, targeted or
controlled release with top-notch biocompatibility and biodegradability.
In this review, we examined the different types of pesticides, the
merits, and demerits of synthetic pesticides and biopesticides, but more
importantly, we x-rayed appropriate and sustainable approaches to
improve the acceptability and commercial usage of microbial pesticides,
phytopesticides, and nanobiopesticides for plant nutrition, crop
protection/yield, animal/human health promotion, and their possible
incorporation into the integrated pest management system.

Piezoelectric Biosensors for Organophosphate and Carbamate Pesticides: A Review
9 September 2014
Abstract
Due
to the great amount of pesticides currently being used, there is an
increased interest for developing biosensors for their detection. Among
all the physical transducers, piezoelectric systems have emerged as the
most attractive due to their simplicity, low instrumentation costs,
possibility for real-time and label-free detection and generally high
sensitivity. This paper presents an overview of biosensors based on the
quartz crystal microbalance, which have been reported in the literature
for organophosphate and carbamate pesticide analysis.

City Ignores Reports of Toxic Soil in Residences, Sidewalks in Coconut Grove, Reports Show
2014
Last
fall, Miami leaders finally admitted they'd known for years that the
long-shuttered Old Smokey trash incinerator in Coconut Grove had
poisoned the earth with toxic ash. But they've also insisted
contamination is contained within a 4.5-acre, fenced-off facility.
However,
new reports obtained by New Times contradict that claim, revealing
instead that testing this summer found that residential properties and
public rights of way adjacent to Old Smokey had dangerous levels of
heavy metals and other highly toxic substances. And though the findings
arrived in June, city officials have failed to notify residents, ignored
repeated demands from county regulators to fence off dangerous sites
and remove the toxin-laced soil, and refused to investigate the extent
of the contamination.

In the Florida Everglades, a Greenhouse Gas Emissions Hotspot
November 6, 2023
Drainage
has exposed the fertile soils of the Everglades Agricultural Area, a
region responsible for much of the nation’s sugar cane.
ORLANDO,
Fla.—It used to be the water spilled over Lake Okeechobee’s southern
shore, flowing eventually into the sawgrass prairies of the Florida
Everglades. For thousands of years the marsh vegetation flourished and
died here in an endless cycle, the plant remains falling beneath the
slow-coursing water to form a rich layer of organic soil called peat.
Over
time the fertile soil, along with the subtropical climate and abundance
of water, drew the attention of farmers, who as far back as the 1880s
began digging canals to drain away the water and expose the peat for
planting.
Today this region, known as the Everglades
Agricultural Area, is among the nation’s most bountiful, raising rice,
sod, vegetables like lettuce, celery and corn and most notably sugar
cane, making Florida the country’s top producer of the crop.
Growing
evidence suggests that draining the water and exposing the peat also
has made the region a significant source of greenhouse gas emissions,
which are warming the global climate and contributing to impacts like
hotter temperatures, rising seas and more damaging hurricanes.
The
Everglades represent Florida’s most important freshwater resource. The
watershed spans much of the peninsula, encompassing the Kissimmee River,
Lake Okeechobee, sawgrass prairies to the south and Florida Bay.
Various efforts over the last century to drain the Everglades, the
largest steered by the U.S. Army Corps of Engineers, have made modern
Florida possible and left the river of grass drastically altered. A $21
billion federal and state effort to restore the Everglades is among the
most ambitious of its kind in human history.
The Everglades
Agricultural Area hugs the southern shore of Lake Okeechobee, the
state’s largest lake. Emissions here especially are a concern because,
although vast swaths throughout the watershed have been drained, this
region historically harbored the greatest deposits of peat, said
Meenakshi Chabba, ecosystem and resilience scientist at the Everglades
Foundation, an advocacy group that commissioned one recent study on the
emissions.
“This is one little spot nestled in a highly conserved
area that is really a global emissions hotspot,” she said. “Right here
is the Everglades Agricultural Area, which is bleeding greenhouse gas
emissions and leading to global heating.”
The study, conducted by
Winrock International, a nonprofit focused on social, agricultural and
environmental issues, found that sugar cane production in the Everglades
Agricultural Area accounted for more than 7.3 million metric tons of
greenhouse gas emissions annually, an amount equivalent to that from 1.6
million gas-powered passenger vehicles driven for one year. The scope
of the emissions would place the region among the top 100 greenhouse gas
polluters in the U.S., in a league with the likes of Nebraska Public
Power District (7.6 million metric tons) and East Kentucky Power
Cooperative (7.3 million metric tons), which are 82nd and 83rd on the
list, said Steve Davis, chief science officer at the Everglades
Foundation.
The vast majority of the agricultural area’s
emissions, 84 percent, were a result of drainage leading to peat
oxidation and loss, according to the study. The researchers also
examined emissions related to agricultural equipment (3.8 percent),
pre-harvest field burning (1.7 percent), drainage canals (1 percent),
pesticides (0.7 percent) and fertilizers (0.6 percent), among other
sources. Emissions associated with the processing of sugar cane were
excluded because the region’s mills and refineries are powered through
the combustion of sugar cane by-products, the study said.
Florida’s
largest sugar growers characterized the study as inaccurate and based
on faulty data and analysis. U.S. Sugar, responsible for nearly 10
percent of all the sugar produced in the U.S., pointed out the region
plays an important part in providing the nation’s food and that cane is a
crop that absorbs carbon. Florida Crystals Corp., another leading
producer of sugar cane, said its farmers have taken steps to minimize
peat loss and greenhouse gas emissions by focusing, for instance, on
minimizing soil disturbance and keeping soils covered...

Greenwashing Florida – From "Fuel Farms" to "Resiliency Facilities"
February 12, 2024
TALLAHASSEE,
FL - Florida stands at a pivotal moment, facing a transformation that
threatens to reshape its landscape and compromise the well-being of its
communities. Senate Bills 1624 and 1628, and their companion House Bills
(collectively "Bills"), currently under consideration, are not merely
pieces of legislation; they represent a concerted effort to rebrand the
expansion of fuel storage and distribution facilities in Florida as a
noble endeavor to enhance resiliency. However, advocates and activists
are attempting to expose the cloaking of corporate interests in the
guise of environmental stewardship for what it truly is: a deceptive
practice that undermines local autonomy and jeopardizes environmental
integrity.
At the heart of this issue lies the creation and
operation of fuel distribution and storage facilities by Belvedere
Terminals, a wholly owned subsidiary of Grupo Mexico, a Mexican mining,
transportation, and infrastructure corporation. What initially appears
as an innocuous effort to bolster energy infrastructure is, in reality, a
calculated move to establish above-ground fuel storage facilities
across Florida. This aggressive expansion plan, disguised under the
label of "resiliency facilities," threatens to irreversibly alter the
fabric of our state.
The terms "fuel farms" and "resiliency
facilities" may sound reassuring, but they serve as thinly veiled
attempts to greenwash the true nature of these projects. By portraying
the construction of fuel storage and distribution facilities as vital
components of resiliency planning, proponents of these Bills seek to
garner public support while obscuring the potential risks and
consequences.
The implications of this deceptive maneuver extend
far beyond mere semantics. By rebranding fuel storage and distribution
facilities as fuel farms or resiliency facilities, proponents seek to
circumvent scrutiny and silence dissent. This greenwashing of corporate
interests undermines the democratic process and erodes the rights of
local communities to determine their own fate. Will Floridians continue
to be misled by such rhetoric?
SB 1624, disguised as a champion
for Florida's alleged energy crisis, masks a sinister reality: a scheme
orchestrated for Grupo Mexico, a company with an abysmal safety record,
to force unwanted fuel distribution and storage facilities into
unwilling communities.
There is a legitimate concern that Grupo
Mexico's control over Florida's fuel supply and infrastructure could
compromise the state's energy security as well as Homeland Security.
Grupo Mexico’s potential control over Florida’s railway infrastructure
and fuel storage demands close scrutiny. Balancing economic interests
with security imperatives is crucial to safeguarding our state and
nation.
What many people may not realize is that the previously
American-owned Florida East Coast Railway (FEC), a vital artery of our
region's economy and transportation network for over 100 years, has been
discreetly acquired by Grupo Mexico. This transformation holds
significant implications for Florida communities, raising concerns about
transparency, accountability, and the potential impact on local jobs,
safety, and the environment.

How to Prevent Red Tide – Florida’s Efforts to Control Red Tide
May 24, 2023
Researchers call it "sea sawdust," and it has a friendly relationship with the organism that causes red tide.
Florida
researchers are watching an algae bloom drifting offshore of the Tampa
Bay area — and no, it’s not red tide or a looming blobof seaweed.
Scientists
are monitoring a patchy cloud of “sea sawdust” that has ebbed and
flowed in the Gulf of Mexico for nearly a week, according to the Florida
Fish and Wildlife Research Institute. The blue-green algae species,
known as Trichodesmium, is often found in tropical waters and blooms off
Southwest Florida.
The good news: It’s not known to be toxic. The bad news: It leaves behind nitrogen that can feed red tide.
Sea
sawdust earns its nickname from the opaque, brownish hue it reflects as
it gathers on the sea surface, according to Kate Hubbard, the director
of the state’s Center for Red Tide Research. From above, thick blooms
can resemble oil slicks.
“It really stands out,” Hubbard said in
an interview. “When you’re on the water, it pops out as something that
looks different than really any other type of algae.”
