Long thought to be chemically so inert as to be biologically
inactive, emerging studies combined with old data from industry
files establish that perfluorooctane sulfonate (PFOS) is a
persistent organic pollutant, with poorly understood but
significant
health risks to wildlife and people.
The PFOS story is likely to emerge as one of the apocryphal
examples of 20th century experimentation with widespread
chemical exposures: prolific use and almost no testing for
safety,
until unexpectedly and almost serendipitously, it is discovered
as a
contaminant virtually everywhere. And as is often the case in
these
stories, the company producing PFOS products possessed
information hinting at its risks but chose not to share their
data with
regulators or the public for years.
Extremely resistent to environmental breakdown, PFOS is now a
ubiquitous contaminant, found in polar bears in the Arctic,
dolphins
in Florida, seals and otters in California, albatross in the
mid-Pacific, and people world-wide. Traditional scans for
persistent pollutants missed this exposure for a long time
because
unlike most POPs, PFOS doesn't accumulate in fatty tissue.
Instead it binds to proteins.
Data accumulating on its toxicity provide as yet uncertain
answer
about its impacts. Long assumed by regulators to be inert and
thus
safe, evidence suggesting unsuspected risks lay largely
unexamined in EPA and company files. They then became too
ominous to ignore.
Used as the key ingredient in Scotchgard, the 3M-made fabric
protector, PFOS has been part of consumer culture for over 40
years, valued for its ability to protect materials from stains
because
it repels both water and oil. It is widely used in a variety of
industrial and consumer products, ranging from fire
extinguishing
foams to wrapping for microwave popcorn and other food
products.
In spring 2000, Scotchgard's manufacture, 3M, surprised almost
everybody by announcing they would eliminate their line of
PFOS-related products by 2002.
When 3M announced it was removing Scotchgard and related
chemicals from its product line the company was lauded for its
environmental responsibility. According to 3M, it was
eliminating a
profitable part of its business--worth some $300 milliion per
year--on the basis of precautionary concerns raised because
PFOS was accumulating in a wide diversity of species, including
people "at extremely low levels." 3M's press release disclaimed
any health threats, asserting that over 700 studies established
the
chemical's safety.
As detailed by an EPA analysis (pdf file) of 3M's own documents,
however, disturbing information had been accumulating for some
time about PFOS toxicity.
For example:
According to EPA's assessment of 3M data, PFOS caused
postnatal deaths (and other developmental effects) in offspring
in a
3M-run 2-generation reproductive effects rat study (NOAEL of 0.1
mg/kg/day and LOAEL of 0.4 mg/kg/day). At higher doses in this
study, all progeny in first generation died while at the LOAEL
many
of the progeny from the second generation died. It is very
unusual
to see such second generation effects." A 3M study (pdf file)
of the
effect of PFOS on monkeys found that exposed individuals
exhibited "low food consumption, excessive salivation, labored
breathing, hypoactivity, ataxia, hepatic vacuolization and
hepatocellular hypertrophy, significant reductions in serum
cholesterol levels, and death." EPA summarizes its assessment by
observing: "PFOS accumulates to a high degree in humans and
animals. It has an estimated half-life of 4 years in humans. It
thus
appears to combine Persistence, Bioaccumulation, and Toxicity
properties to an extraordinary degree" (emphasis added).
This story is far from over. Research is now concentrating on
characterizing the mechanisms of PFOS toxicity, identifying the
full
range of impacts, getting a fuller picture of contamination
levels in
people and wildlife, and examining related perfluorinated
compounds, including perfluorooctanoic acid (PFOA), a chemical
involved in the production of Teflon.
Comment:
Another example of fluorine based chemical harming humans and
building in the environment.
Many fluorine based chemical cause this problem. HF from coal
plants in the long term will outweight the H2SO4 and HCl
emissions, due to calcium affinity making the fluoride levels
rise in
soils and plants, and likewise in man.

Righting the wrongs of the Manhattan Project's deceit and
treachery national security methods using openness and
accountability.
Toxic metals and fluorides concentrate in lymph nodes and cause
damage to macrophage mitochondrial DNA, leading to illnesses.
See the analysis at http://members.aol.com/magnu96196/cfs.html
In the 1980's, Oak Ridge managers established a national
alliance
of DOE friendly supplanted activists and old DOE scientists to
mislead gullible fluoride affected sick workers and communities
in
order to fabricate a health mystery and avoid the extreme
liabilities
of the fluorides health damage to uranium gas diffusion chemical
plant workers and communities.
