PFAS – what does the science say? (opens in new tab)

Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) are a large class of chemicals, sometimes dubbed ‘forever chemicals’. They are used widely in consumer products such as non-stick pans, rinse-aid, cosmetics and stain-resistant clothing/carpets. They all have a strong carbon-fluorine bond which typically means they break down slowly in the environment.
