AFFF

PFAS are a family of chemical pollutants of emerging concern. They are extremely useful in processing and manufacturing non-stick and stain-resistant consumer products, as well as foams used in firefighting, but they are also particularly persistent in the environment, and in humans! Efforts are being made to control the spread of these chemicals, and it’s important to understand both where they are coming from and how they move through the environment. In a recent study, researchers show how snails and crabs might be better informants about PFAS contamination sources than fish.
