A R a a 6 -c r? \5 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 not noted. The test sample is FC-203. 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 of the fluorochemical component of the test sample. METHOD:_________________________________________________________ Method: Not given. Type: Continuous flow GLP: No Year completed: Not given. Species: Salmo gairdnen Supplier: Not given. Analytical monitoring: pH, and DO Exposure period: 96-hours Statistical methods: Not given. Test fish age: Not given. Length and weight: Not given. Loading: Not given. Pretreatment: None Test conditions: Dilution water: Not given. Dilution water chemistry: Not given. Lighting: Not given. Stock and test solution preparation: Stock solution of 160 g/L prepared, then diluted with dilution water to prepare the sample concentrations. Concentrations dosing rate: Flow-through Stability of the test chemical solutions: Not given. Exposure vessels: Not given. Number of replicates: Not given. Number of fish per replicate: Not given. Number of concentrations: five plus a blank control Water chemistry during the study: pH range (0 - 96 hours): 7.3 - 7.8 Dissolved oxygen range (0-96 hours): 7.2 - 9.0 mg/L 000506 RESULTS Nominal concentrations: Bk control, 25, 50,100, 200, and 400 mg/L. Element values: 96-hour LC50 = >400 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 LC50for rainbow trout was determined to be >400 mg/L. No mortality or sublethal effects observed at this concentration. 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 data sheets. Sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
