BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity: Perfluorooctanoic acid, ammonium salt; may also 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% C5, C6, and Czperfluoro analogue compounds. METHOD: Method: EPA approved standard method numbers 507 and 508A. Type: Aerobic (BOD) and Dichromate reflux (COD) GLP: No Year completed: 1987 Contact time: 20 days Inoculum: Not noted RESULTS Chemical Oxygen Demand (COD): 825 mg/kg* Biochemical Oxygen Demand (BOD): 5-Day: 140 mg/kg 10-Day: 500 mg/kg 20-Day: 710 mg/kg ` Average of two tests. CONCLUSIONS No reliable conclusions can be derived from this study. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY Reliability: Klimisch ranking 4. Summary was created using only a listing of test values. The original study procedure and raw data were not found. However, there was a discrepancy noted in the data values. Data 003703 was reported as "mg/L" by the testing laboratory, but was entered as "mg/kg" values in the 3M Environmental Laboratory archive system without proper conversion from volume to mass units. Therefore, the data is invalid as stated. REFERENCES The COD and BOD studies were conducted by Pace Analytical of Minneapolis, MN at the request of the 3M Company, Lab Request number E1282, 5/29/87.
