AK *26 - 0177 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 501 and 895. 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: BOD Ultimate and dichromate reflux COD GLP: No Year completed: 1976 Contact time: 20 days Inoculum: Source not given. RESULTS_____ !_____________________ Lot 501 Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 11-Day: 15-Day: 20-Day: 500.000 mg/L 45.000 mg/L 218.000 mg/L 304.000 mg/L 319.000 mg/L Lot 895 Chemical Oxygen Demand (COD): Biochemical Oxygen Demand (BOD): 5-Day: 11-Day: 15-Day: 20-Day: 480.000 mg/L 45.000 mg/L 263.000 mg/L 270.000 mg/L 263.000 mg/L 001411 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. CON CLU SIONS_______________________________________________ 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. 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.
