BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity: Perfluorooctanoic acid, ammonium salt; mayalso be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, FC116, FC-126, FC-169, or FC-143. (Octanoic acid, pentadecafluoro-, ammonium salt, CAS# 3825-26-1) Remarks: The 3M production lot number was not noted The test sample is FC-126 and is referred to by the testing laboratory as E1282-1 and E1282-2. It's purity was not sufficiently characterized, though current information indicates it is a mixture of 78 - 93% test substance and 7 - 22% Cs, Cs, and C7 perfluoro analogue compounds. METHOD: Method: EPA approved standard method numbers 507 and 508A. Type: Aerobic (BOD) and Dichromate reflux (COD) GLP: No `Year completed: 1967 Contact time: 20 days Inoculum: Not noted RESULTS Chemical Oxygen Demand (COD): 825 mg/kg" Biochemical Oxygen Demand (BOD): 5Day: 140 mgkg 10-Day: 500 mglkg 20-Day: 710 mgkg *Average of two tests. CONCLUSIONS No reliable conclusions can be derived from this study. Submitter: 3M Company, Environmental Laboratory, P.O.
