Perfluorooctanesulfonic and Perfluorooctanoic Acid
Ad from 1975
Huh?
You may not be familiar with these complex organic compounds (generically
referred to as PFAS chemicals), but undoubtedly you have been using (or have
been exposed to) products with these chemicals for years. They’ve been around
since the 1970s, manufactured by 3M and later Dupont. Perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic
acid (PFOA) were in an incredibly vast array of everyday products, from
Teflon-coated non-stick pans to water-repellant clothes. But there’s a catch…
actually several nasty catches.
“[They]
accumulate in your blood causing cancer, damaging
your immune system, injuring your liver, spleen, bone marrow, and increasing
cholesterol and triglycerides levels putting you at risk of heart attacks. Fun
stuff.
“These
fluorochemicals were the basis for the company’s success, going from a small
business called the Minnesota Mining and Manufacturing Company to a $120
billion conglomerate [3M]. The company used the
discoveries from the Manhattan Project–which used fluorine to distill the
uranium for the first atom bomb that dropped over Hiroshima–to develop a magic
fluorocarbon fluid called PFOA. Dupont used PFOA to create Teflon, a coating
used by hundreds of companies to manufacture miraculous–and toxic–non-stick cookware.”

OK,
we are constantly discovering stuff that is really bad for us that we have been
using for years. What’s difference here? Big reality: The use of PFOS and PFOA
chemical components, which actually accounted for 3M’s meteoric rise in
corporate value, were apparently known by 3M to be mega-toxic since the 1970s.
“[The]
dangers presented by these industrial chemicals have been known for decades,
not just a few months or years. A lawsuit filed by [the State of] Minnesota
against 3M, the company that first developed and sold PFOS and PFOA, the
two best-known PFAS compounds,
has revealed that the company knew that these chemicals were accumulating in
people’s blood for more than 40 years. 3M researchers documented the chemicals in
fish, just as the Michigan scientist did, but they did so back in the 1970s.
That same decade, 3M scientists realized that the compounds they produced were
toxic. The company even had evidence back then of the compounds’ effects on the
immune system, studies of which are just now driving the lower levels put forward
by the ATSDR, as well as several states and the European Union.
“The suit, which the Minnesota
attorney general filed in 2010, charges that 3M polluted groundwater with PFAS
compounds and ‘knew or should have known’ that these chemicals harm human
health and the environment, and ‘result in injury, destruction, and loss of
natural resources of the State.’ The complaint argues that 3M ‘acted with a
deliberate disregard for the high risk of injury to the citizens and
wildlife of Minnesota.’ 3M settled the suit for $850 million in February, and
the Minnesota Attorney General’s Office released a large set of documents —
including internal studies, memos, emails, and research reports — detailing
what 3M knew about the chemicals’ harms.
“Some
of the documents had been under seal since 2005 as a result
of a separate lawsuit over PFAS contamination in Minnesota. And the documents
had been in the EPA’s possession for at least 18 years: In 2000, 3M gave the
EPA hundreds of documents it had withheld from the agency, resulting in more
than $1.5 million in penalties in 2006 for 244
violations of the Toxic Substances Control Act. Even so, for years the EPA did
nothing. Even as a few government officials and company scientists understood
the vast dangers they posed, PFAS were allowed to spread into groundwater
and then drinking water, into people and their children, into animals, plants
and the food system where they remain today…
“As
a staff epidemiologist at 3M, Geary Olsen has had a wealth of data at his
fingertips. The company he’s worked for since at least 1998 makes more than
55,000 products and has more than 90,000 employees. Olsen had access to
internal information about both and has been able to combine them to pursue the
kinds of scientific questions most researchers can only dream of being able to
ask and answer…
“Olsen’s
findings, written up in an draft report in October
2001, were clear. There was a positive association between the amount of PFOA
in workers’ blood and their levels of cholesterol and triglycerides, states the
report, on which Olsen is listed as the principal investigator. The report
devoted more than 20 tables to triglycerides and cholesterol, detailing a
relationship that later studies would confirm: PFOA increased people’s levels
of triglycerides, which are a type of fat, and cholesterol, both of which can
increase the chance of heart disease. The results were in keeping with rat
evidence, as the report noted.
“Yet
less than two years later, when Olsen and the three co-authors on the report —
all 3M employees — published an article based on the same
research, it downplayed this key finding. Indeed, according to the study, which
ran in the March 2003 issue of the Journal of Occupational and Environmental
Medicine, ‘There were no substantial changes in hematological, lipid, hepatic,
thyroid, or urinary parameters consistent with the known toxicological effects
of PFOS or PFOA’ — a statement that appears to contradict the authors’ earlier
finding.” Sharon Lerner writing for the July 31st TheIntercept.com.
And no, this is not an example of the Trump administration’s trying to shut
down the EPA; this particular horrible casts a dark shadow across many prior
administration on both sides of the aisle.
We
live an exceptionally complex world of too many ideas, too much technology, too
many financial structures… such that very few of us are equipped to understand
and deal with. Instead, we depend on our government to protect us from
substantial harm generated by companies and powerful people who do not care
about people, who only care about profits, and are unmoved by the “collateral
damage” of their knowing manufacture of killing and health-destroying
substances. We desperately need our government to do its job, to maintain those
necessary regulations to protect the public, and to the extent that they fail
to do so, we need to hold those at the top of the companies and those
administrative agencies personally responsible for the harm they have caused or
allowed to continue unchecked.
I’m Peter Dekom, and the last thing
most Americans need is a pullback on regulations that otherwise protect us from
harm because they are inconvenient to greedy profiteers willing to kill or
decimate people for a buck… with governmental complicity.
