ACUTE TO XIC ITY TO FISH
TEST SUBSTANCE_______________________________________________
Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-201. (1Octanesulfonic add, perfluoroalkyl sulfonate salts (5) + (5140P)) (CAS # 2795-39-3)
Rem arks: The 3M production lot number was Lot 1. The test sample is FC -201. Its purity was not suffidently characterized, though current information indicates it is a mixture of 6% PFOS, 36% diethylene glycol butyl ether, 36.44% water, 12% Sultone foamer, 9% sodium octyl sulfate, 0.5% sodium lauryl sulfate, and 0.06% benzotriazole.
The foilowing summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the toxicity o f the fiuorochemicai component o f the test sample.

W ater chem istry during the study:
000167
pH range (0-96 hours): 7.0 - 7.0 (control exposure) 6.8 - 6.9 (750 mg/L exposure)*
Tem perature range (0-96 hours): 69 - 70 F
Dissolved oxygen range (0-96 hours): 4.7 - 5.6 mg/L (control exposure) 4.0 - 5.0 mg/L (750 mg/L exposure)*
* 750 mg/L (second highest concentration) exposure values used because the highest concentration used resulted in total mortality by 72 hours.
R E S U L TS __________________________________________ ______________
Nom inal concentrations: Bk control, 100, 250, 50 0,7 50, and 1,000 mg/L Elem ent values: 96-hour LC50 = 526 (397 - 631) mg/L
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.
C O N C L U S IO N S ___________________________________________________
The test substance 96-hour LC50 for fathead minnow was determined to be 526 mg/L with a 95% confidence interval of 397 to 631 mg/L.
Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133
DATA QUALITY____________________________ _______________________
Reliability: Klimisch ranking 3. Testing lacks record of methodology used. The sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
R E F E R E N C E S ____________________________________________________
The test was conducted by the 3M Company, Environmental Laboratory, St. Paul, MN, Lab Request number 2563, 1975.
