ACUTE TOXICITY TO FISH (FATHEAD MINNOW) TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredtoas PFOS, FC-95, or as a component ofL-4647. (1Octanesulfonicacid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber isgivenas both NB# 52393-334, and cc803-17. The testsample is1.356% solutionofL-4647. Current informationindicatesitisa mixtureof6.6% PFOS, 20% polyethyleneglycol, 20% hexahydricalcohol,39% sodium decylsulfate1,3.2% Hydroxy foamer, 1% sodium ethylhexylsulfate,0.1% methylhydroquinone, and 0.1% biphenylols,odium salt,tetrahydrate. The followingsummary applies to a mixture with incompletely charactedzed concentradons of impudties. Data may not accurately reflectthe toxicityof the fluorochemical component of the testsample. METHOD: Method: Not given. Type: Acute statidcefinifivaend range-finding GLP: No Year completed: 1960 Species: Pimephalespromelas Supplier:Commerical supplierB,rady,NE. Analyticalmonitoring: Temperature,pH, and dissolvedoxygen. Exposure period: 96-hours Statisticamlethods: The LC50 valueswere determinedby themoving average angle method. Test fishage: Juveniles Length and weight: Average length 32 -36 mm Average weight 0.37- 0.40g (wet) Loading: 0.46- 0.75g/L Pretreabnent:None Test conditions: Dilutionwater: Carbon-filterweedllwater Dilutionwater chemistry: Not given.
