Opinion: ‘Forever Chemicals’ Are Everywhere. It’s Time to Rein Them in

Polyfluoroalkyl and perfluoroalkyl substances, or PFAS, are a class of man-made chemicals that break down slowly in the environment, can accumulate in the human body and have been linked to all manner of negative health effects from cancer to high cholesterol.
