What are PFASs?
Perfluoroalkyl and polyfluoroalkyl substances (together known as PFASs) are a class of man-made chemicals, not found naturally in the environment. PFOA (sometimes known as “C8”) and PFOS are the two PFASs that have been the most extensively produced and therefore are the most studied of these chemicals. Both of these chemicals are very persistent in the environment and in the human body.
