ACUTE TO XIC ITY TO FISH (M UM MICHOG)
TEST SUBSTANCE________________________________________________
Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-780. (1Octanesulfonic acid) (CAS # 2795-39-3).
Rem arks: The 3M production lot number was not available. The test sample is FC-780. Current information indicates it is a mixture of 0.5% PFOS, 14% diethylene glycol butyl ether, 76.95% water, 5.5% urea, 1.0% Sultone foamer, 1.15% sodium octyl sulfate, 0.8% polyoxyethylene monooctylphenyl ether, 0.05% sodium lauryl sulfate, and 0.05% tolyltriazole.
The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the toxicity o f the fluorochemical component o f the test sample.

Element values based on nominal concentrations. Rem arks: Testing was conducted on a mixture as described in the Test Substance Remarks field. The values reported apply to that mixture and not the fluorochemical proportion alone. CONCLUSIONS ________________________________________________ The 96-hour LC50 for FC-780 was >5000 mg/L. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY____________________________________ ______________ R eliability: Klimisch ranking = 4. Values are from a summary sheet only raw data not found. Study lacks description and records of the method followed. There is no characterization of the test substance purity and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
