ARSL&6 - ACUTE TOXICITY TO AQUATIC INVERTEBRATES (COROPHIUM VOLUTATOR) TEST SUBSTANCE_______________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-603EF. (1Octanesulfonic acid) (CAS # 2795-39-3).

26-Week Capsule Toxicity Study with Perfluorooctanesulfonic Acid Potassium Salt (PFOS) in Cynomolgus Monkeys Current Summary as of May 4, 2000 The purpose of this study was to identify the earliest clinically measurable biological response from repeated daily exposure to potassium perfluorooctane sulfonate (PFOS) and to correlate this response to serum concentrations for purposes of risk assessment and medical monitoring of exposed populations.
