ftR . &A6 - 0 7 1 0 ACUTE TO XIC ITY TO FISH TEST SUBSTANCE_______________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-203A. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not provided. The test sample is FC-203A. Current information indicates it is a mixture of 1.34% PFOS, 25% diethylene glycol butyl ether, 67.85% water, 2.66% Sultone foamer, 3% sodium octyl sulfate, 0.1% sodium lauryl sulfate, and 0.05% tolyltriazole. The following summary applies to a mixture wit!i incompletely characterized concentrations o f impurities. Data may not accurately reflect the toxicity o f the fluomchemical component o f the test sample. M E T H O D :________________________________________________________ Method: Not given Type: Acute static GLP: No Year completed: 1975 Species: Pimephales promelas Supplier: Not given. Analytical monitoring: Temperature, pH, and DO Exposure period: 96-hours Statistical methods: LC50 values calculated using graphic interpolation. Test fish age: Juvenile Length and weight: Average length = 2 in. Average weight = 1.5 g (wet) Loading: Not given. Pretreatment: None Test conditions: Dilution water: Carbon-filtered St. Paul 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 (0-96 hours): 7.0 - 7.0 (control exposure) 000987 6.7 - 6.9 (750 mg/L exposure)* Tem perature range (0-96 hours): 69 - 70 F Dissolved oxygen range (0-96 hours): 4.7 - 5.6 mg/L (control exposure) 3.9 - 4.8 mg/L (750 mg/L exposure)* * 750 mg/L (second highest concentration) exposure values used because the highest concentration used resulted in total mortality at 72 hours. RESULTS____________________________________________________ ___ Nom inal concentrations: Bk control, 100, 250, 500,750, and 1000 mg/L Elem ent values: 96-hour LC50 = 300 mg/L Element values based on nominal concentrations Rem arks: 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 test sample 96-hour LC50 for fathead minnow was determined to be 300 mg/L. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY___________________________________________________ R eliability: Klimisch ranking 3. Testing lacks record of methodology used. There is a lack of characterization of the test sample. Test solutions were not analyzed for test substance concentrations and confirmation of the amount of fluorochemical proportion in the solution.
