Per- and polyfluoroalkyl substances (PFAS) are a group of several thousand synthetic compounds that are found in a wide range of commodities. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS) are two of the most regularly investigated and discussed PFAS.
This brief from the Association of State and Territorial Health Officials (ASTHO) gives an overview of the public health significance of PFAS exposures, some challenges related to PFAS for state health agencies, and recent federal actions to protect communities from PFAS.
