ACUTE TOXICITY TO FISH (RAINBOW TROUT) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonawthei,ch may alsobe referredtoas PFOS, FC-95,oras a component ofFC-203. (1Octanesulfoniaccid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was 4. The testsample isFC203. Currentinformatioinndicateistisa mixtureof1.34% PFOS, 35% diethyleneglycolbutylether,37.85% water,20% ethyleneglycol,2.66 % Sultonefoamer,3% sodium octylsulfate0,.1% sodium laurylsulfatea,nd 0.05% tolyltriazole. The followingsummary appliesto a mixture with incompletely characterizedconcentrationsof impurities.Data may not accurately reflecttoxicityof the fluorochemicalcomponent of the testsampie.
