A R & A & - 0700 ACTIVATED SLUDGE RESPIRATION INHIBITION TEST TEST SUBSTANCE __________________________________________ Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95 or as a component of FC-201AF. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was not noted. The test sample is FC-201AF. Current information indicates it is a mixture of 3% PFOS, 18.59% diethylene glycol butyl ether, 37.81% water, 14% ethylene glycol, 8.25% Acrylic foamer, 9% sodium octyl sulfate, 0.3% sodium lauryl sulfate, 3% triethanolamine, 6% sulfonated alkyl ether salts, 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. METHOD____________________________________________________ Method: OECD Guideline 209 Test type: Static acute GLP: No Year Completed: 1995 Analytical monitoring: Dissolved oxygen, temperature, and pH. Statistical methods: Results were determined by calculation of the % inhibition in respiration rate. Test organism source: Activated sludge mixed liquor collected from the Metro Wastewater Treatment Plant, St. Paul, MN. Test condition: Dilution water: Millipore Milli-QTM water Synthetic sewage: per OECD method Reference and test solution preparation: A stock solution of the reference substance, 3,5-dichlorophenol, was prepared by dissolving 500 mg in 10mL 1N NaOH, diluted to 30mL with Millipore Milli-QTM water, then brought to the point of incipient precipitation with 1 N H2S 04 and diluted to 1L with Milli-QTM water. The pH of the reference solution was measured to be 7.3. Test substance was added directly to the test vessels. Test vessels: Not given. Number of concentrations: one plus blank control, in duplicate and 1 reference substance Temperature: 19.3-20.7C . Total suspended solids and pH on day of testing: 4.2 g/L (TSS in final: 1.7 g/L), initial pH 6.0 and final pH 6.5. Element Basis: Respiration inhibition as determined by oxygen consumption. 000308 Remarks: Uptake rates corrected to 20C for calculations. R E S U L T S _____________________________________________ Nominal concentrations: Blank controls and 1000 mg/L in duplicate plus one reference substance at 10 mg/L. Element values: 30-minute EC50 = >1000 mg/L 3-hour EC50 = >1000 mg/L Element values based on nominal concentrations. Remarks: 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 test substance 3-hour EC50for activated sludge respiration inhibition was determined to be >1000 mg/L. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY_______________________________________________ R eliability: Klimisch ranking = 2. This study meets 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.
