How the Planet-Altering Disaster of "Forever Chemicals" Was Kept Secret

How 3M Hid the 'Forever Chemicals' Crisis for Decades

ProPublica's Sharon Lerner uncovers how 3M kept the dangers of PFAS 'forever chemicals' secret for decades. After years of reporting, a former 3M scientist, Kris Hansen, reveals that in the 1990s she discovered PFOS in the blood of the general public, not just factory workers. Her boss acknowledged the finding with 'This changes everything' but then retired, and the company continued production. This podcast episode explores how a corporate giant concealed a planet-altering disaster.

    > They have developmental effects, immune effects. Thyroid, liver, hormonal systems. Some cause cancer, kidney cancer, obesity. They bind to proteins in your blood, and they change how systems in your bodies work.

    Is there any evidence that the amounts found in humans using non stick pans, for example, and not those drinking water downstream from an industrial source of “forever chemicals”, have any of these effects?
