ACUTE TOXICITY TO FISH (FATHEAD MINNOW)
TEST SUBSTANCE
Identity: A mixture containing perfluorooctanesulfonate, which may also be
referred to as PFOS, FC-95, or as a component of FC-206A. (1-
Octanesulfonic acid) (CAS # 2795-39-3).
Remarks: The 3M production lot number was cc 785-22.
The test sample is FC-206A. Current information indicates it is a mixture of
0.92% PFOS, 18.75% diethylene glycol butyl
Hydroxy foamer, 1.75% sodium octyl sulfate,
