ACUTE TOXICITY TO FISH (MUMMICHOG)
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredtoas PFOS, FC-95, oras a component ofFC-780. (IOctanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The 3M productionlotnumber was notavailableT.he test sample isFC-780. Currentinformationindicateistisa mixtureof0.5% PFOS, 14% diethyleneglycolbutylether,76.95% water,5.5% urea,1.0% Sultonefoamer,1.15% sodium oetylsulfate0,.8% polyoxyethylene monooctylphenylether,0.05% sodium laurylsulfatea,nd 0.05% tolyltriazole.
The followingsummary applies toa mixture with incompletely characterizedconcentrations of impudties. Data may not accurately reflectthe toxicityof the fluorochemical component of the testsample.
