Perfluoroalkyl and polyfluoroalkyl substances, or PFAS, have earned the nickname “forever chemicals” from their extraordinary ability to stick around in the environment long after they’ve been used.
These synthetic compounds, commonly used in consumer products and industrial applications for their water- and grease-resistant properties, are now found practically everywhere in the environment.
While many chemicals will degrade relatively quickly after they’re disposed of, PFAS can stick around for up to 1,000 years. This durability is great for their use in firefighting foams, nonstick cookware, waterproof clothing, and even food packaging.
