BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredto as PFOS, FC-95, or as a component ofFC-206 or L3243. (1-Octanesulfonaicid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumbers were 510 and 512. The test sample isFC-206. Currentinformationindicatesitisa mixtureof0.67% PFOS, 17.5% diethyleneglycolbutylether,78.91% water,1.33% Sultone foamer, 1% sodium octylsulfate0,.04% sodium laurylsulfate0,.5% polyoxyethylenemonooctylphenylether,and 0.05% benzotriazole. The followingsummary applies to a mixture with incompletely characterizedconcentrations of impurities.Data does not accurately reflectdegradation potentialof the fluorochemical component of the testsample. METHOD: Method: Not noted. Type: Aerobic GLP: No Year completed: 1975 Contact time: >5 days lnoculum: Source notgiven. Remarks: UltimateBOD testterminateddue todrop of incubation temperature. RESULTS Lot 510 Chemical Oxygen Demand (COD): BiochemicalOxygen Demand (BOD): 5-Day: Lot 512 Chemical Oxygen Demand (COD): BiochemicalOxygen Demand (BOD): 5-Day: 428,000 mg/L <56,250 mg/L 432,000 mg/L <56,250 mg/L Remarks: Testingwas conducted on the mixtureas describedinthe Test Substance Remarks field.The valuesreportedapplytothatmixtureand not the fluorochemicalproportionalone. CONCLUSIONS No conclusionsgiven.
