MICROBIOS MICROTOX TOXICITY TEST
TE$T_SUB.STANCE_______________________________________ _
Identity: Mixture containing perfluorooctanesulfonate which may also be referred to as PFOS, FC-95, or as a component of FC-3003. (1Octanesulfonic acid) (CAS # 2795-39-3).
Remarks: The 3M production lot number was not given. The test sample is FC-3003. Current information indicates it is a mixture of 1% PFOS, 15% diethylene glycol butyl ether, 79.39% water, 2% Sultone foamer, 1.5% sodium octyl sulfate, 1% sodium decyl sulfate, 0.06% sodium lauryl sulfate, and 0.05% benzotriazole.
The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data may not accurately reflect toxicity of the fluorochemical component of the test sample.
METHOD:____________________________________________________
Method: Microbios Microtox "BASIC" Procedure Test type: Static acute GLP: No Year Completed: 1997 Species: Photobacterium phosphoreum Analytical monitoring: pH and osmotic condition. Exposure period: 30-minutes Statistical methods: EC50 values calculated by statistical linear regression program provided for Microtox Test organism source: Microbios' Reagent. Test conditions:
Diluent: Millipore Milli-QTM water Test temperature: Not noted. Stock and test solution preparation: A 1 g/L primary stock solution was prepared b^ dissolving 100 mg of test substance in 100 mL of Millipore Milli-Q water. The pH of the stock solution was then adjusted from 5.7 to 7.7 using 1.0 N NaOH. An osmotic adjustment was made using 200 mg NaCI dissolved in 10 mL stock solution. Appearance of test solutions was noted as "clear". All test solutions were made by proportional dilutions. Exposure vessels: 4 mL cuvettes. Number of replicates: two Number of concentrations: Four plus a blank control Element basis: Percent light loss
RESULTS____________________________________________________
002693
Nominal concentrations: Blank control, 62.5,125, 250, and 500 mg/L
Element value:
5-minute EC5o = 311 (289 - 335) mg/L 15-minute ECso = 171 (161 - 181) mg/L 30-minute EC5o= 120 (118 - 122) mg/L
Element values based on nominal concentrations.
Remarks: Testing was conducted on the mixture as described in the Test Substance Remarks field. The values reported apply to that mixture and not the fluorochemical proportion alone.
CONCLUSIONS_________________________ ___ ______________
The test substance 30-minute EC50 for Photobacterium phosphoreum was determined to be 120 mg/L with a 95% confidence interval of 118 to 122 mg/L.
Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, MN, 55133
DATA QUALITY________________________________________________
Reliability: Klimisch ranking = 2. The study meets all the criteria for quality testing. However, sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
REFERENCES________________________________________________
