BACK TO MAIN TOXICITY TO FISH (Saltwater Rainbow Trout) TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as PFOS or FC-95. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-, potassium salt, CAS # 2795-39-3) Remarks: The test substance is a white powder of uncharacterized purity.

Decomposition of Perfluorooctane Sulfonate by Combustion Processes Introduction To understand the potential degradation pathways for perfluorinated chemicals, it was necessary to model the thermodynamics of incineration processes.
