We want to get rid of PFAS, but that’s easier said than done | Science

PFAS stands for poly- and perfluoroalkyl substances. It is a collective name for millions of similar substances that have two very useful properties due to their chemical structure. The fabrics are very water and grease repellent, making them useful in, for example, rain suits, baking paper and extinguishing foam. In addition, PFAS are very strong. The particles consist of carbon and fluorine atoms, which are very tightly bonded to each other. This makes the molecules almost impossible to break.
