Short for per-and polyfluoroalkyl substances PFAS are a class of thousands of man-made chemicals that have been around since the 1940s. They all contain carbon-fluorine bonds which are one of the strongest chemical bonds in organic chemistry. Per- and polyfluoroalkyl substances PFAS are a group of human-made chemicals that were first used in the 1940s followed in subsequent decades by the development of thousands of new PFAS chemistries.
The CDC has listed a host of health effects believed to be associated with exposure to those. Per- and polyfluoroalkyl substances PFAS are chemicals that have been used in a wide range of consumer and industrial products since the 1940s due to their resistance to grease.
