Va. Plant By Juliet Eilperin Washington Post Staff Writer Friday, July 9, 2004; Page A03 ============================= The chemical, perfluorooctanoic acid, is a soaplike material used in making stain- and stick-resistant surfaces and materials for a wide array of products, including Gore-Tex and pizza boxes. The substance, also known as C-8 or PFOA, has been linked in industry studies to cancer and birth defects in animals. The agency had been pressed to act on C-8 by the Environmental Working Group, a private advocacy group, and by Ohio and West Virginia residents who are suing DuPont over claims that it contaminated soil and drinking water around the company's Parkersburg, W.Va., plant. Both welcomed the agency's move but said it could have taken tougher action. ============================= PerFluoroOctanoic Acid (PFOA) --> Per - ¹L/¥þ, Fluoro - ¬t, Octanoic Acid - ¨¯»Ä (¥Ò»Ä->¤@ÓºÒì¤lªºßn»Ä, ¤A»Ä->¨âÓºÒì¤lªºßn»Ä, ¤þ»Ä->¤TÓºÒì¤lªºßn»Ä, ¤B»Ä->¥|ÓºÒì¤lªºßn»Ä, ... ¨¯»Ä->¤KÓºÒì¤lªºßn»Ä).
