Per- and polyfluoroalkyl substances (‘PFAS’) are a group of manufactured chemicals that have been widely used globally, since the 1950s, in the manufacture of household and industrial products that resist heat, stains, grease and water. Examples of PFAS uses include fire-fighting foams; fume suppressants for chrome plating; stain protection for carpets, fabric and furniture; cosmetics; sunscreens; paper coating; plastics; electronic parts; insecticides; photographic materials; aviation hydraulic fluid and medical devices.
