Hidden Studies, Decades-Old, Could Have Curbed PFAS Problem: Scientist

"Studies conducted in the late 1970s and early 1980s were kept under wraps by chemical companies as pollution spread across the US, according to an editorial published today."

An editorial published in Environmental Health today suggests that research on perfluorinated alkylate substances (PFAS) and their dangerous health effects was not revealed until several decades after it was conducted.

The lack of publicly available research has prevented proper guidelines for levels of the chemical compounds, including in drinking water, Philippe Grandjean, a professor at University of Southern Denmark and Harvard's T.H. Chan School of Public Health, argued in his piece.

In the editorial, Grandjean said studies conducted up to four decades ago found health effects, including on the immune system, from PFAS chemicals, but those studies were hidden by production companies, like 3M Co."
