Manufacturers of ‘forever chemicals’ tried to cover up the dangers they posed for more than 30 years, a new report claims.
Researchers at the University of California, San Francisco, who reviewed dozens of company documents, found executives were first alerted to the health risks in 1961, but scientists said that they failed to raise the alarm until the 1990s.
Internal documents revealed chemical manufacturers DuPont and 3M were facing studies warning the chemicals, dubbed per- and polyFluorinated Substances (PFAS), could cause liver enlargement, poisonings and birth defects in children.
