Teflon and DuPont

I’ve always heard awful, awful things about DuPont, a company that pretty much owns the feudal state of Delaware and considers employees to be serfs. This Intercept story is illustrative:

Concerns about the safety of Teflon, C8, and other long-chain perfluorinated chemicals first came to wide public attention more than a decade ago, but the story of DuPont’s long involvement with C8 has never been fully told. Over the past 15 years, as lawyers have been waging an epic legal battle — culminating as the first of approximately 3,500 personal injury claims comes to trial in September — a long trail of documents has emerged that casts new light on C8, DuPont, and the fitful attempts of the Environmental Protection Agency to deal with a threat to public health.

This story is based on many of those documents, which until they were entered into evidence for these trials had been hidden away in DuPont’s files. Among them are write-ups of experiments on rats, dogs, and rabbits showing that C8 was associated with a wide range of health problems that sometimes killed the lab animals. Many thousands of pages of expert testimony and depositions have been prepared by attorneys for the plaintiffs. And through the process of legal discovery they have uncovered hundreds of internal communications revealing that DuPont employees for many years suspected that C8 was harmful and yet continued to use it, putting the company’s workers and the people who lived near its plants at risk.

The best evidence of how C8 affects humans has also come out through the legal battle over the chemical, though in a more public form. As part of a 2005 settlement over contamination around the West Virginia plant where Wamsley worked, lawyers for both DuPont and the plaintiffs approved a team of three scientists, who were charged with determining if and how the chemical affects people.

In 2011 and 2012, after seven years of research, the science panel found that C8 was “more likely than not” linked to ulcerative colitis — Wamsley’s condition — as well as to high cholesterol; pregnancy-induced hypertension; thyroid disease; testicular cancer; and kidney cancer. The scientists’ findings, published in more than three dozen peer-reviewed articles, were striking, because the chemical’s effects were so widespread throughout the body and because even very low exposure levels were associated with health effects.
