PFAS Makers Concealed Health Dangers Despite Warnings and Breakthroughs

Makers of PFAS, or "forever chemicals," covered up their health risks for decades, according to an analysis of previously secret industry documents by UC San Francisco researchers. The paper documents a timeline of what industry knew versus public knowledge and analyzes strategies the chemical industry used to suppress information or protect their harmful products. PFAS are widely used chemicals in clothing, household goods, and food products, and are highly resistant to breaking down, making them ubiquitous in people and the environment.
