Perfluorooctanoic Acid, also commonly
referred to by its acronym PFOA, is a synthetic chemical that is not
naturally occuring in the environment. PFOA is used to refer to not
only the Perfluorooctanoic Acid, but also its principal salts and Perfluorooctane
sulfonate (PFOS). These groups of compounds are typically used to aid
in the manufacturing of fluoropolymers. These polymers have valuable
properties of fire resistance, oil, stain and grease repellence. They
are also commonly used in fire fighting foams. Fluorotelomers will
thermally and biologically decompose to form the PFOAs.
Recent studies by the EPA have indicated the potential need for concern and the
necessity for additional analytical testing and monitoring. PFOAs have been determined
to bioaccumulate and are highly persistent. Continued testing has shown that
this class of compounds is widely distributed in the environment. Toxicological
studies have shown that exposure to PFOAs can result in developmental/reproductive
toxicity, liver damage and possibly cancer. |
