ACUTE TOXICITY TO FISH (RAINBOW TROUT) IEST~S ~ UBSTANCE
Identity:
A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-203. (1Octanesulfonic acid) (CAS # 2795-39-3).
Remarks: The 3M production lot numberwas not noted. The test sample is FC-203. Current information indicates it is a mixture of 1.34% PFOS, 35% diethylene glycol butyl ether, 37.85% water, 20% ethylene glycol, 2.66 % Sultone foamer, 3% sodium octyl sulfate, 0.1% sodium lauryl sulfate, and 0.05% tolyltriazole.
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.
