2. Background (PFOS & PFOA) 2.1. Perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) are perfluorinated chemicals and commercially available in the form of salts, derivatives and polymers. PFOS has been identified as being persistent, bio -accumulative in the environment and toxic in terms of human health.

It was added to Annex B of the Stockholm Convention on Persistent Organic Pollutants in May 2009. Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Exhibit 1: Physical and Chemical Properties of PFOS and PFOA (ATSDR 2015; EFSA 2008; EPA 2016b, 2016c) Property PFOS (Free Acid) PFOA (Free Acid) Chemical Abstracts Service (CAS) number 1763-23-1 335-67-1 Physical description (physical state at room temperature and atmospheric pressure) White powder (potassium salt) PFOA and PFOS are no longer manufactured or imported in the United States, but similar “replacement chemicals for PFOA and PFOS such as GenX, may be just as persistent,” Pinney said.

Human exposure to per- and polyfluoroalkyl substances (PFAS) is a public health concern that ATSDR, the CDC, and NCEH are helping our local, territorial, tribal, state, and federal partners address.

Children with high levels of PFOA and PFOS in their blood produce lower levels of antibodies after vaccination, which could reduce their ability to fight off infections. 3M, the primary manufacturer of PFOS, began a voluntary phase-out of the chemical in 2000.
