&4 f t 6 - 0 7 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-206 or L3243. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot numbers were 510 and 512. The test sample is FC-206. Current information indicates it is a mixture of 0.67% PFOS, 17.5% diethylene glycol butyl ether, 78.91% water, 1.33% Sultone foamer, 1% sodium octyl sulfate, 0.04% sodium lauryl sulfate, 0.5% polyoxyethylene monooctylphenyl ether, and 0.05% benzotriazole. The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data does not accurately reflect degradation potential of the fluorochemical component of the test sample. METHOD:____________________________________________________ Method: Not noted. Type: Aerobic GLP: No Year completed: 1975 Contact time: >5 days Inoculum: Source not given. Remarks: Ultimate BOD test terminated due to drop of incubation temperature. RESULTS_____________________________________________ Lot 510 Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 428,000 mg/L <56,250 mg/L Lot 512 Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 432,000 mg/L <56,250 mg/L 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. 001408 CONCLUSIONS No conclusions given. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY_______________________________________________ Reliability: Klimisch ranking 3. Study lacks description and records of the method followed. Additionally, the study was terminated prematurely due to incubation difficulties. 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.
