/IR tf -O 1 BIODEGRADATION (BOD/COD/TOC) TEST SUBSTANCE Identity: Perfluorooctanoic acid, ammonium salt; may also be referred to as PFOA ammonium salt, Ammonium perfluorooctanoate, PFO, FC116, FC-126, FC-169, or FC-143. (Octanoic acid, pentadecafluoro, ammonium salt, C A S # 3825-26-1) Remarks: The test sample is FC-143. The referenced study is only a summary. Current information indicates FC-143 is a mixture of 96.5 -100% test substance and 0 - 3.5% C 6, C 7, and Cgperfluoro analogue compounds. The 3M production lot number was 261. METHOD: Method: Not noted. Type: Aerobic (BOD). Unknown for COD and TOC. GLP: No Year completed: 1977 Contact time: 14 days Innoculum: Not noted RESULTS Total Organic Carbon (TOC)*: Chemical Oxygen Demand (COD)*: Biochemical Oxygen Demand (BOD): 5-Day: 14-Day: * Duplicated studies. 186.000 mg/kg 238.000 <4000 mg/kg <1800 mg/kg Nil <10,200 mg/kg CONCLUSIONS No reliable conclusions can be derived from this study.
