What are Per and Polyfluoroalkyl Substances – PFAS?
Per- and polyfluoroalkyl substances (PFAS) are a large family of chemicals that contain carbon, fluorine and other elements. Historically, these may have been referred to under the term ‘PFC’ which stood for Per Fluorinated Chemicals. However, PFC is also used to mean ‘Per Fluorinated Carbons’ ie greenhouse gases and so this term is no longer used for PFAS compounds.
