“These documents reveal clear evidence that the chemical industry knew about the dangers of PFAS and failed to let the public, regulators, and even their own employees know the risks.”

An analysis of previously secret documents published Wednesday sheds new light on how chemical corporations aped Big Tobacco by conspiring to conceal the extreme toxicity of a class of synthetic compounds contaminating the Earth’s air, water, soil, plants, and animals—including most of the world’s people.

Commonly called “forever chemicals” because they do not biodegrade and accumulate in the human body, per- and polyfluoroalkyl substances (PFAS)—which include PFOS, PFOA, and GenX—have myriad uses, from nonstick cookware to waterproof clothing to firefighting foam. According to the U.S. Agency for Toxic Substances and Disease Registry, PFAS is linked to cancers of the kidneys and testicles, low infant weight, suppressed immune function, and other adverse health effects. It is found in the blood of 99% of Americans and a similar percentage of people around the world.
