BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatmea;y also be referredtoas PFOS, FC-95, or as a component of FC-206CF or FC-206CF-X. (1-Octanesulfoniacid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was 101. The testsample isFC206CF. Currentinformationindicatesitisa mixtureof 0.5% PFOS, 10% diethyleneglycolmonobutyl ether,78.08% water,1.375% acrylicfoamer, 1.5% sodium octylsulfate1,% sulfonatedalkylethersalts,6.0% urea,0.5% triethnaolamine, and 0.05% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data does not accurately reflectthe degradation potentialof the fluorochemical component of the testsample. METHOD: Method: EPA 410.1 COD GLP: No Year completed: 1991 Contact time: 20 days Inoculum: Not given. and EPA 405.1 CBOD RESULTS Chemical Oxygen Demand (COD): BiochemicalOxygen Demand (BOD): 5-Day: 1O-Day: 20-Day: 340,000 mg/kg 160,000 mg/kg 170,000 mg/kg 180,000 mg/kg Remarks: Testingwas conducted on the mixtureas described inthe Test Substance Remarks field.The values reportedapplytothatmixtureand not the fluorochemicalproportionalone. CONCLUSIONS No conclusionsgiven. Submitter: 3M Company, EnvironmentalLaboratory,P.O. Box 33331, St. Paul,Minnesota,55133 DATA QUALITY Reliability:Klimischranking= 2. The study meets allcriterifaorquality testing.However, the inoculum isnot properlycharacterized.The sample puritywas not properlycharacterizedand the study lacksanalytical confirmationofthe amount offluorochemicalproportioninthe solution.
