AH A56 - 0730 ACUTE TOXICITY TO FISH (FATHEAD MINNOW) 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. METH O D ;____________________________________________________ Method: Not given. Type: Acute static GLP: No Year completed: 1976 Species: Pimephales promelas Supplier: Not given. Analytical monitoring: Temperature, pH, and dissolved oxygen. Exposure period: 72-hours Statistical methods: Not given. Test fish age: Juvenile Length and weight: Average length = 45 mm Average weight = 1.4 g (wet) Loading: Not given. Pretreatment: None. Test conditions: Dilution water: Carbon filtered well water (aerated) Dilution water chemistry: Not given. Lighting: Not given. Stock and test solution preparation: Test material amended to black dirt formulated (premixed) used in greenhouse research 1:1, mixed with sand, type silty clay soil. 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: four plus soil control and no soil control. Water chemistry during the study: 001526 pH range (0-72 hours): 7.3 - 7.3 (control exposure) 7.0 - 7.1 (10000 mg/L soil exposure) Temperature range (0-96 hours): 48 - 49 F Dissolved oxygen range (0-96 hours): 7.6 - 8.3 mg/L (control exposure) 5.3 - 7.9 mg/L (10000 mg/L soil exposure) RESULTS____________________________________________________ Nominal concentrations: Blank control, no soil control, 10,100,1000, and 10000 mg/L soil. Element values: None given. 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___________________________________________ No conclusions given. 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.
