M A H 6 _ 07J+7 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-203CE. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 519. The test sample is FC203CE. Current information indicates it is a mixture of 1.84% PFOS, 30% diethylene glycol butyl ether, 60.23% water, 2.56% Sultone foamer, 3.1% sodium octyl sulfate, 2.1% polyoxyethylene monooetylphenyl ether, 0.12% sodium lauryl sulfate, and 0.05% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability o f the fluorochemical component o f the test sample. METHOD:____________________________________________________ Method: BOD - Standard Methods 507, COD - Standard Methods 508. Type: Aerobic GLP: No Year completed: 1989 Contact time: 20 days Inoculum: Source not given. RESULTS _______ _____________________________________ Total Organic Carbon (TOC): 216,300 mg/kg (calculated) Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 10-Day: 20-Day: 740.000 mg/kg 370.000 mg/kg (duplicate) 46.000 mg/L 260.000 mg/L 470.000 mg/L CONCLUSIONS______________________________________________ No conclusions given. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 001056 DATA QUALITY Reliability: Klimisch ranking 3. The inoculum is not properly characterized. There is no characterization of the test substance purity, and analytical measurement of the test concentrations. The testing was conducted on a mixture with chemicals having varying degrees of biodegradability, leading to potential misinterpretation of the results.
