A h * 2.6 - 0 7 S Z 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-206 or L3243. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 1. The test sample is FC206 (L-3243). 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 fluorochemicai 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: Dissolved oxygen, and temperature Exposure period: 96-hours Statistical methods: LC5ovalue calculated using graphic interpolation. Test fish age: Juveniles Length and weight: Average length = 38.1 mm Average weight = 0.9 g (wet) Loading: Not given. Pretreatment: None. Test conditions: Dilution water: Dechlorinated 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: Temperature range (0-96 hours): 50 F Dissolved oxygen range (0-96 hours): 001466 4.9 - 5.9 mg/L (control exposure) 4.0 - 5.2 mg/L (3000 mg/L exposure)* * 3000 mg/L (intermediate concentration) exposure values used because the highest two concentrations resulted in total mortality by 72 hours. RESULTS________________________________________________________ Nominal concentrations: Blank control, 2000, 2500, 3000, 3500, and 4000 mg/L. Elem ent values: 96-hour LC50 = 2500 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. C O N C L U S IO N S ___________________________________________________ The FC-206 96-hour LC50 for rainbow trout was determined to be 2500 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. The sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
