M zz - 07S3 BIODEGRADATION (BOD/COD) TEST SUBSTANCE____________________________________________ Identity: Mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-203CF-X or FC-203CF. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 101. The test sample is FC203CF. Current information indicates it is a mixture of 1% PFOS, 20% diethylene glycol monobutyl ether, 70.2% water, 2.75% Acrylic foamer, 3% sodium octyl sulfate, 1% triethanolamine, 2% sulfonated alkyl ether salts, and 0.05% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data does not accurately reflect the degradation potential of the fluorochemical component of the test sample. METHOD.:____________________________________________________ Method: EPA410.1 COD and EPA 405.1 CBOD G L P : No Year completed: 1991 Contact time: 20 days Inoculum: Not given. RESULTS____________________________________________________ Chemical Oxygen Demand (COD): 750.000 mg/kg Biochemical Oxygen Demand (CBOD): 5-Day: 350.000 mg/kg 10-Day: 400.000 mg/kg 20-Day: 720.000 mg/kg Remarks: Testing was conducted on the mixture as described in the Test Substance Remarks field. The values reported apply to that mixture and not the fluorochemical proportion alone. CONCLUSIONS No conclusions given. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 001213 DATA QUALITY Reliability: Klimisch ranking = 2. Testing meets all criteria for quality testing. The inoculum is not properly characterized. The sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
