Scientists Warn Against Attempts To Change Definition of 'Forever Chemicals'

A group of 20 internationally renowned scientists have issued a strong warning against attempts to narrow the definition of 'forever chemicals' in what they describe as a politically or economically motivated effort to weaken regulation of the potentially harmful chemicals. From a report: Per- and polyfluoroalkyl substances (Pfas) are a large group of synthetic chemicals used for their oil-, water- and stain-resistant properties in a range of consumer and industrial products from waterproof clothing and non-stick cookware to firefighting foams and electronics.

Their molecular structure makes them resistant to degradation, earning them the nickname 'forever chemicals.' In the last few years there has been growing awareness of the problems associated with Pfas, and a push for more stringent regulation, resulting in the banning of certain forms. A group of scientists are now raising the alarm about efforts, including by some individuals and groups in the International Union of Pure and Applied Chemistry (IUpac), to narrow the current international definition of Pfas in ways that could exclude certain chemical subgroups.
