AR 226 -- O878 BIODEGRADATION (BOD/COD) JEST~S ~ UBSTANCE Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-787 or FC787X. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not noted. The test sample is FC-787. Current information indicates it is a mixture of 0.73% PFOS, 10% diethylene glycol monobutyl ether, 79.74% water, 5% ethylene glycol, 1.47% propane Sultone foamer, 0.73% sodium octyl sulfate, 0.73% sodium decyl sulfate, 0.75% xanthan gum, 0.75% magnesium sulfate, 0.10% N-(3chioroallyl)hexaminium chloride, and 0.05% benzotriazole. The following summary applies to a mixture with incompletely characterized concentrationsof impurities. Data does not accurately reflect the degradation potential of the fluorochemical component of the test sample. mewoo: Method: EPA or other acceptable methodologies GLP: No Year completed: 1990 Contact time: 20 days Inoculum: Source not given. RESOTS Chemical Oxygen Demand (COD): 350,000 mg/kg 320,000 mg/kg (replicate) Biochemical Oxygen Demand (CBOD): 5-Day: 160,000 mg/kg - 10-Day: 220,000 mg/kg 20-Day: 200,000 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. No conclusions given. Submitter: 3M Company, Environmental Laboratory, P.O.
