ACUTE TOXICITY TO FISH
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonawthei,ch may alsobe referretdoas PFOS, FC-95,oras a component ofFC-203A. (1Octanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The 3M productionlotnumber was not provided.The test sample isFC-203A. Currentinformatioinndicateistisa mixtureof1.34% PFOS, 25% diethyleneglycolbutylether,67.85% water,2.66% Sultone foamer,3% sodium octylsulfate0,.1% sodium laurylsulfatea,nd 0.05% tolyltriazole.
The followingsummary appliesto a mixture with incompletely characterizedconcentrationsof impudties. Data may not accurately reftct the toxicityof the tluorochemicalcomponent of the testsample.
