PFAs are absolutely everywhere in the environment, and throughout the food chain. I have friends who live in Thornton Cleveleys, where the highest recorded levels of PFAs have recently been recorded near the outflow of a chemical plant. It’s seemingly historical as there have been no PFAs measured in the effluent from the plant since these measurements were started some tome ago. They’ve probably been accumulating for many decades and goes to show just how pervasive and persistant these chemicals are.
