09W 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 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 incompietely characterized concentrations o f impurities. Data may not accurately reflect the toxicity o f the fluorochemical component o f the test sample. M E T H O D _________________________________________________________ Method: OECD 209 Test type: Static acute GLP: No Y ear Com pleted: 1985 A nalytical m onitoring: Dissolved oxygen concentrations S tatistical m ethods: Results were determined by calculation of the % inhibition in respiration rate. Test organism source: Activated sludge mixed liquor collected from the Metro W aste Treatment Plant, St. Paul, MN. Test condition: Dilution w ater: Not given. Synthetic sew age: per OECD 209 Reference and te st solution preparation: Not given. T est vessels: Not given. Num ber o f concentrations: five plus blank control Tem perature: Not given. Total suspended solids and pH on day o f testing: Not given. Elem ent Basis: Respiration inhibition as determined by oxygen consumption. RESULTS________________________________________________________ Nom inal concentrations: 2 Blank controls, 100,180, 320, 560, and 1000 mg/L Elem ent values: 30-minute EC50 = >1000 mg/L 002978 3-hour EC50 = >1000 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 3-hour EC50 for 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 3. Study lacks description and records of the method followed. The inoculum was not properly characterized. There is no characterization of the test substance purity, and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
