AR 6 -0 7 3 ! ACUTE TOXICITY TO FISH (BLUEGILL SUNFISH) 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 number was 501. The test sample is FC206. 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 may not accurately reflect toxicity of the fluorochemical component of the test sample. METHOD: Method: Not given. Type: Acute flow-through GLP: No Year completed: 1978 Species: Lepomis macrochirus Supplier: Commenai supplier in Brady, NE. Analytical monitoring: Temperature, pH, and dissolved oxygen. Exposure period: 24-hours Statistical methods: Not given. Test fish age: Juveniles Length and weight: Average length = 30 mm Average weight = 0.25 g (wet) Loading: 0.31 g/L Pretreatment: None Test conditions: Dilution water: Carbon-filtered well water Dilution water chemistry: Not given. Lighting: Not given. Stock and test solution preparation: Not given Diluter Flow rate: Not given. Concentrations dosing rate: Continuous. Stability of the test chemical solutions: Not noted. Exposure vessels: Vessels containing 16 L test solution. Number of replicates: 1 Number of fish per replicate: 20. Number of concentrations: five plus a blank control Water chemistry during the study: 001530 pH range (0-24 hours): 7.9 - 8.0 (control exposure) 8.0 - 8.0 (2000 mg/L exposure) Temperature range (0-24 hours): 18 C Dissolved oxygen range (0-24 hours): 7.3 - 9.0 mg/L (control exposure) 7.0 - 9.0 mg/L (2000 mg/L exposure) RESULTS Nominal concentrations: Blank control, 300, 600, 1200, 1800, and 2000 mg/L Element values: 24-hour LC5o(FC-206 only)= >2000 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 24-hour LC50 for bluegill sunfish was determined to be >2000 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. The sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
