WASHINGTON, Aug 19 — “Forever chemicals” used in daily items like nonstick pans have long been linked to serious health issues — a result of their toxicity and extreme resistance to being broken down as waste products.
PFAS, or per- and polyfluoroalkyl substances, were first developed in the 1940s and are now found in a variety of products, including nonstick pans, water-resistant textiles and fire suppression foams. Chronic exposure to even low levels has been linked to liver damage, high cholesterol, reduced immune responses, low birth weights and several kinds of cancer.
PFAS’ indestructability comes from their carbon-flouride bonds, one of the strongest types of bonds in organic chemistry. At one end of the molecule, there is a group of charged oxygen atoms which can be targeted using a common solvent and reagent at mild temperatures of 80-120 degrees Celsius, decapitating the head group and leaving behind a reactive tail.
