Recommendation: The SAB reviewed the scientific evidence on 12 PFAS chemicals (PFNA, PFOA, PFHpA, PFHxA, PFBA, PFOS, PFHxS, PFBS, GenX, and PFPAs and PFPiAs) and their salts. Across the entire category of perfluoroalkyl/per- and polyfluoroalkylether acids (PFAAs), the SAB found many similar hazards, as described in more detail below. The SAB also reviewed the Organization for Economic Cooperation and Development (OECD) list of PFAAs and PFAA precursors, including information about known and potential breakdown pathways. OECD has created as comprehensive a list as possible of PFAS, including precursors. In addition, the SAB reviewed scientific information showing that the PFAA precursors break down into the PFAAs via a number of pathways.
