The US Environmental Protection Agency (EPA) has been reviewing data and developing a draft risk assessment for Perfluorooctanoic Acid (PFOA). PFOA is a synthetic chemical, sometimes referred to as “C8”, used by chemical companies and manufacturers to make non-stick cookware, water repellant coatings for all-weather clothing and fabrics, food packing, gaskets, O-rings, and hoses. It is chiefly used in producing fluoropolymers which are employed in almost all commercial industry segments including aerospace, automotive, building/construction, chemical processing, electrical and electronics, semiconductor, and textile industries. The durability of PFOA due to its specific chemical structure prevents breakdown in the environment which leads to widespread persistence in the environment. It is this persistence which prompted the EPA to conduct a further evaluation of PFOA and its potential to adversely affect human health.
