EFSA: Per- and polyfluoroalkyl substances (PFAS)
Per- and polyfluoroalkyl substances (PFAS) consist of a large group of man-made chemicals used for their water-, grease-, and stain-resistant properties in products like non-stick cookware, food packaging, water-repellent clothing, and firefighting foams. The active substances in pesticides can also be PFAS.
