Per- and polyfluoroalkyl substances ( PFAS ) are synthetic chemicals first developed in the 1940s to withstand heat and repel water and grease.

They have been detected virtually everywhere on Earth , from the top of Mount Everest to inside human blood and brains.

There is firm evidence that at least one of the more than 4,000 human-made chemicals called PFAS causes cancer, but researchers are still trying to understand their broader health impacts.
