ARSL6- 0723* ACUTE TOXICITY TO FISH (RAINBOW TROUT) TEST SUBSTANCE_______________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-203. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 4. The test sample is FC203. Current information indicates it is a mixture of 1.34% PFOS, 35% diethylene glycol butyl ether, 37.85% water, 20% ethylene glycol, 2.66 % Sultone foamer, 3% sodium octyl sulfate, 0.1% sodium lauryl sulfate, and 0.05% tolyltriazole. The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data may not accurately reflect toxicity o f the fluorochemical component of the test sample. METHOD:________________________________________________________ Method: Not given. Type: Acute static GLP: No Year completed: 1974 Species: Salmo gairdneri Supplier: Not given. Analytical monitoring: Temperature, pH, and DO Exposure period: 96-hours Statistical methods: Not given. Test fish age: Juvenile Length and weight: Average length = 1.5 in Average weight = 0.9 g (wet) Loading: Not given. Pretreatment: None. Test conditions: Dilution water: Carbon filtered city water, St. Paul, MN Dilution water chemistry: Not given. Lighting: Not given. Stock and test solution preparation: Not given. Concentrations dosing rate: Once Stability of the test chemical solutions: Not noted. Exposure vessels: Not given. Number of replicates: 1 Number of fish per replicate: Not given. Number of concentrations: five plus a blank control Water chemistry during the study: pH range (0-hours only): 7.1 - 7.2 0005S4 Temperature range (0-96 hours): 4 8 - 4 9 F Dissolved oxygen range (0-96 hours): 4.7 - 5.7 mg/L (control exposure) 4.2 - 5.2 mg/L (1250 mg/L exposure) RESULTS________________________________________________________ Nominal concentrations: Bk control, 125, 312.5, 625, 937.5, and 1250 mg/L Element values: 96-hour LC50 = 1250 mg/L Element values based on nominal concentrations 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___________________________________________________ The test sample 96-hour LC50 for rainbow trout was determined to be 1250 mg/L. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY___________________________________________________ Reliability: Klimisch ranking = 3. Testing lacks record of methodology used and documentation. Sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
