M <256 _ 0 9 1 3 MICROBIOS MICROTOX TO XICITY TEST TEST SUBSTANCE_______________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FX-3103. (1Octanesulfonic acid) (CAS # 2795-39-3). Rem arks: The 3M production lot number was not noted. The test sample is FX-3103, 3%. Current information indicates it is a mixture of 0.96% PFOS, 20% diethylene glycol butyl ether, 50.56% water, 15% ethylene glycol, 4.32% sodium octyl sulfate, 6.0% polyoxyethylene monooctylphenyl ether, 2.5% propane sultone foamer, 0.5% sodium nitrate, 0.06% sodium lauryl sulfate, and 0.1% benzotriazole. 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. METHOD:________________________________________________________ Method: Microbios Microtox "BASIC" Procedure T est type: Static acute GLP: No Y ear Com pleted: 1985 Species: Photobacterium phosphoreum Analytical monitoring: Not given. Exposure period: 30-minutes S tatistical m ethods: EC50 values calculated by statistical linear regression program provided for Microtox Test organism source: Microbios' Reagent. Test conditions: Diluent: Not given. Test tem perature: Not noted. Stock and test solution preparation: Not given. Exposure vessels: 4 mL cuvettes. Num ber o f replicates: two Num ber o f concentrations: Four plus a blank control Elem ent basis: Percent light loss RESULTS________________________________________________________ Nom inal concentrations: Blank control, 100, 250, 750, and 1000 mg/L Element value: 5-minute EC50 = >1000 mg/L 15-minute EC50 = >1000 mg/L 002974 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 15-minute EC50 for Photobacterium phosphoreum was determined to be >1000 mg/L. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, MN, 55133 DATA QUALITY__________________________ ________________________ R eliability: Klimisch ranking 3. 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.
