Perfluorinated compounds (PFCs) are used in a wide variety of applications as a surfactant because of their ‘wetting’ properties. Other applications include moisture, stain and fat repellency for consumer products (e.g. leather and carpets) and as polymerization aid for the production of fluorinated polymers (e.g. Teflon). Because of the wide distribution in wildlife and human samples the production of perfluorinated octane sulfonate (PFOS) some producers (e.g. 3M) decided to terminate the production PFOS and related compounds on a voluntary basis (EPA, 2000). Other PFCs (e.g. perfluorinated octanoic acid (PFOA)) remain in production by various producers for a range of applications. Dupont voluntarily plans to reduce PFOA residuals in consumer products with 98% by 2007
