: AR R26 _ 0885 ACUTE TOXICITY TO AQUATIC INVERTEBRATES (DAPHNIA MAGNA) IESTSUBSTANCE Identity: Mixture containing perfluorooctanesulfonate which may also be referred to as PFOS, FC-95, or as a component of FC-3003. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not given. The test sample is FC-3003, identified by the laboratory as R1331. Current information indicates it is a mixture of 1% PFOS, 15% diethylene glycol butyl ether, 79.39% water, 2% Sultone foamer, 1.5% sodium octyl sulfate, 1% sodium decyl sulfate, 0.06% sodium lauryl sulfate, 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. MET Oe ------------------t Method: OECD Guideline 202 Type: Acute static GLP: No Year completed: 1997 Species: Daphnia magna oxygen Supplier: In-house cultures maintained at AScl-DETD, Duluth, MN. Analytical monitoring: Temperature, pH, conductivity, and dissolved Exposure period: 48-hours Test organism age: <24 hours old Statistical methods: No calculations performed, based on study results. Test conditions: Dilution water: Dechlorinated City of Duluth, MN tap water post- carbon filter, aerated for 24 hourspriorto use. Dilution water chemistry: Hardness: 44 mg/L as CaCO3 Alkalinity: 42 mg/L as CaCO3 Conductivity: 145 ymhos/cm pH: 8.05 . Lighting: Cool-white fluorescent lights. A daily photoperiod of 16 hours light __ and 8 hours dark was maintained throughout the testing period. Stock and test solution preparation: The test solutions were prepared by direct addition of test substance, followed by mechanical stirring at ambient lab temperature. Exposure vessels: 250 mL beakers with 200 mL test solution.
