AKZ2G - BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC -201. (1Octanesulfonic acid, perfluoroalkyl sulfonate salts (5) + (5140P)) (CAS # 2795-39-3) Rem arks: The 3M production lot number was not noted. The test sample is FC-201. Its purity was not sufficiently characterized, though current information indicates it is a mixture of 6% PFOS, 36% diethylene glycol butyl ether, 36.44% water, 12% Sultone foamer, 9% sodium octyl sulfate, 0.5% sodium lauryl sulfate, and 0.06% benzotriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect die biodegradability o f die fluorochemical component in the test sample.. METHOD:_____________________________ ___________________________ Method: Not noted.

Study lacks description and records of the method followed. The inoculum is not properly characterized. There is no characterization of the test substance purity, and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
