PFASs--short for perfluoroalkyl substances--are synthetic chemicals of various formulations (including PFCs, PFOA, PFOS and GenX, among others) that are used widely in various products for moisture and stain resistance. Non-stick pans, rain jackets and carpeting are among thousands of different types of consumer goods that now contain one form or another of PFASs.
