What is PFOS/PFOA
Perfluorooctane sulfonic acid (PFOS) and Perfluorooctanoic acid (PFOA) belong to a family of manmade chemicals used for more than 50 years to make products that resist heat, oil, stains, grease, and water. Perfluorinated compounds like PFOS and PFOA are extremely stable and do not breakdown in the environment.
Common uses for per- and polyfuoroakyl substances (PFAS) include:
- Coatings on some food packaging, especially microwave popcorn bags and fast food wrappers
- Non-stick cookware
- Components of fire-fighting foam
- Many industrial applications
