Per- and polyfluoroalkyl substances (PFAS) are a diverse group of synthetic chemicals used in a range of industries, including aviation, automotive, construction, manufacturing and electronics. They are also found in many consumer products, including food packaging and cosmetics. However, they are now known to present a significant threat to human health and the environment due to their persistence, mobility and toxicity, as well as the tendency of some PFAS to bio magnify through the food web.
