PFAS: “Forever Chemicals”
Perfluoroalkyl and polyfluoroalkyl substances – PFAS refers to a large group of over 3000 man-made compounds that include Perfluorooctane Sulfonate (PFOS) and Perfluorooctanoic Acid (PFOA). These chemicals have been used in industrial and consumer products since the 1950s including non-stick products like Teflon, stain and water-resistant fabrics and textiles, cosmetics, polishes, grease-resistant food wrappers and fire-fighting foams.
