Perfluorooctanoic acid (PFOA) is a type of per- and polyfluoroalkyl substances (PFAS) and is part of a broader group of organofluorine compounds. PFOA poses potential risks to human health and the environment due to its toxicity, bioaccumulation, chemical stability, widespread use, and long-range transport.

Perfluorooctanoic acid (PFOA) is one of the per- and polyfluoroalkyl substances (PFAS), a class of substances within a broader universe of organofluorine compounds. PFOA has potential adverse effects on human health and environmental safety because of its toxicity and bioaccumulation. Its innate chemical stability, widespread use, and long-range transport result in PFOA’s ubiquity in the global environment.
