nc-oio-j CHRONIC TOXICITY TO EARLY LIFE STAGE OF FISH TEST SUBSTANCE Identity: Perfluorooctanesulfonate; may also be referred to as 14C78.02, PFOS or FC-95. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, potassium salt, CAS #2795-39-3) Remarks field: The test substance is a white powder. Sample was radiolabeled. Sample purity was not characterized. The following summary is abbreviated due to the fact that this study has been superceded by a more recent test. METHOD Method: Method was developed by E G & G, Bionomic and closely followed those presented in the "Proposed recommended bioassay procedure for egg and fry stages of freshwater fish", U.S. EPA, 1972. Type: Flow-through chronic GLP: No Year completed: 1978 Species: Pimephales promelas RESULTS 30-Day NOEC: 30-Day LOEC: 30-Day MATC: 1 mg/L 1.9 mg/L >1 mg/L and <1.9 mg/L DATA QUALITY Reliability: Klimisch ranking = 2. This study satisfied criteria for quality testing at the time performed, but the analytical methodology was questionable.
