Secret industry documents reveal that makers of PFAS 'forever chemicals' covered up their health dangers

> As early as 1961, according to a company report, Teflon's Chief of Toxicology discovered that Teflon materials had "the ability to increase the size of the liver of rats at low doses," and advised that the chemicals "be handled 'with extreme care' and that 'contact with the skin should be strictly avoided.'" According to a 1970 internal memo, DuPont-funded Haskell Laboratory found C8 (one of thousands of PFAS) to be "highly toxic when inhaled and moderately toxic when ingested." And in a 1979 private report for DuPont, Haskell labs found that dogs who were exposed to a single dose of PFOA "died two days after ingestion." In 1980, DuPont and 3M learned that two of eight pregnant employees who had worked in C8 manufacturing gave birth to children with birth defects. The company did not publish the discovery or tell employees about it, and the following year an internal memo stated, "We know of no evidence of birth defects caused by C-8 at DuPont." Despite these and more examples, DuPont reassured its employees in 1980 that C8 "has a lower toxicity, like table salt." Referring to reports of PFAS groundwater contamination near one of DuPont's manufacturing plants, a 1991 press release claimed, "C-8 has no known toxic or ill health effects in humans at concentration levels detected." > As media attention to PFAS contamination increased following lawsuits in 1998 and 2002, DuPont emailed the EPA asking, "We need EPA to quickly (like first thing tomorrow) say the following: That consumer products sold under the Teflon brand are safe and to date there are no human health effects known to be caused by PFOA." > In 2004, the EPA fined DuPont for not disclosing their findings on PFOA. The $16.45 million settlement was the largest civil penalty obtained under U.S. environmental statutes at the time. But it was still just a small fraction of DuPont's $1 billion annual revenues from PFOA and C8 in 2005. > "As many countries pursue legal and legislative action to curb PFAS production, we hope they are aided by the timeline of evidence presented in this paper," said Woodruff. "This timeline reveals serious failures in the way the U.S. currently regulates harmful chemicals."

**Executive 1:** "Our product causes damage to the environment and people's health? How do we prevent the public finding out?" **Executive 2:** "If we just don't tell anyone, then no one will ever figure it out!" **Executive 1:** "A foolproof plan! Also lets offer giant grants to 'researchers' for carrying out intentionally biased 'studies' that prove our products are safe!" **Executive 2:** "Genius! And I'll make a bunch of patriotic memes about our product, and a lot that accuse anyone questioning its safety of being a gay child molester!"
