M S ia -G - * 1 9 BIODEGRADATION (BOD/COD) TEST SUBSTANCE_______________________________________ __ Identity: A mixture containing perfluorooctanesulfonate; may also be referred to as PFOS, FC-95, or as a component of FC-206CF or FC-206CF-X. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 101. The test sample is FC206CF. Current information indicates it is a mixture of 0.5% PFOS, 10% diethylene glycol monobutyl ether, 78.08% water, 1.375% acrylic foamer, 1.5% sodium octyl sulfate, 1% sulfonated alkyl ether salts, 6.0% urea, 0.5% triethanolamine, 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 o f the test sample. MET HOD;_____________________________________________ Method: EPA 410.1 COD and EPA 405.1 CBOD GLP: No Year com pleted: 1991 Contact tim e: 20 days Inoculum : Not given. RESULTS_____________________________________________ Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 10-Day: 20-Day: 340.000 mg/kg 160.000 mg/kg 170.000 mg/kg 180.000 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. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 001855 DATA QUALITY R eliability: Klimisch ranking = 2. The study meets all criteria for quality testing. However, 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.
