M AA6 _ O7/-S' ACUTE TO XIC ITY TO AQUATIC INVERTEBRATES (DAPHNIA MAGNA) TEST SUBSTANCE________________________________________________ Identity: A mixture containing perfluorooctanesulfonate; may also be referred to as PFOS, FC-95, or as a component of FC-203C and L-5440. (1-Octanesulfonicacid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, potassium salt, CAS # 2795-39-3) Rem arks: The 3M production lot number was 501. The test sample is FC-203C. Current information indicates it is a mixture of 1.47% test substance, 60% water, 30% diethylene glycol butyl ether, 3% sodium octyl sulfate, 3% hydroxy foamer, 10% polyoxyethylene monooctylphenyl ether, 0.12% sodium lauryl sulfate, and 0.05% benzotriazol. The following summary applies to the test sample as a mixture o f the test substance in water solution with incompletely characterized concentration o f impurities. Data may not accurately relate toxicity o f the test sample with that of the fluorochemical component METHOD:__________________________________________________ ____ Method: Not given Type: Static acute GLP: No Year com pleted: 1981 Species: Daphnia magna Supplier: Not given.

Rem arks: Testing was conducted on the mixture of the test substance 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 ___________________________________________________ No mortality was observed during the study. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 ~ DATA QUALITY___________________________________________________ R eliability: Klimisch ranking = 4. Values are from a summary sheet only - raw data not found. Test concentrations not provided. Study lacks description and records of the method followed. There is no characterization of the test substance purity, analytical measurement of the test concentrations, and confirmation of the amount of fluorochemical proportion in the solution.
