ACTIVATED SLUDGE RESPIRATION INHIBITION TEST TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredtoas PFOS, FC-95 or as a component of FC-201AF. (1Octanesulfonicacid)(CAS # 2795-39-3). Remarks: The 3M productionlotnumber was not noted. The testsample isFC-201AF. Currentinformationindicatesitisa mixtureof 3% PFOS, 18.59% diethyleneglycolbutylether,37.81% water,14% ethyleneglycol, 8.25% Acrylicfbamer,9% sodium octylsulfate0,.3% sodium laurylsulfate, 3% t(iethanolamine6,% sulfonatedalkylethersalts,and 0.05% tolyltdazole. The followingsummary applies to a mixtum with incompletely charactedzed concentrations of impudties. Data may not accurately mflect the toxicityof the fluorochemical component of the testsample. METHOD Method: OECD Guideline209 Test type: Staticacute GLP: No Year Completed: 1995 Analyticalmonitoring: Dissolvedoxygen,temperature,and pH. Statisticamlethods: Resultswere determinedby calculatioonfthe% inhibitioinnrespiratiornate. Test organism source: Activatedsludge mixed liquorcollectedfrom the Metro Wastewater Treatment Plant,St.Paul,MN. Test condition: Dilutionwater: MilliporMeilli-OTwmater Synthetic sewage: per OECD method Reference and testsolutionpreparation: A stock solutionofthe referencesubstance,3,5-dichlorophenowla,s prepared by dissolving 500 mg in1OmL 1N NAOH, dilutedto30mL withMilliporMeilli-QTM water,then broughttothe pointofincipienptrecipitatiwointh 1N H2SO4 and dilutedto IL withMilli-CiwTamter. The pH ofthe referencesolution was measured to be 7.3. Test substance was added directltyothe testvessels. Test vessels: Not given. Number of concentrations: one plusblank controli,nduplicateand 1 referencesubstance Temperature: 19.3- 20.7*C. Totalsuspended solids and pH on day of testing: 4.2 g/L (TSS in final1:.7g/L),initiaplH 6.0 and finalpH 6.5. Element Basis: Respirationinhibitioans determined by oxygen consumption. Remarks:Uptakeratescorrectetdo200C forcalculations. RESULTS Nominal concentrations: Blankcontrolsand 1000 mg/L induplicateplus one referencesubstance at 10 mg/L. Elementvalues: 30-minuteEC50=>1000mg/L 3-hour EC50 = >1000 mg/L Element values based on nominal concentrations. Remarks: Testingwas conducted on a mixtureas describedinthe Test Substance Remarks field.The values reportedapply tothatmixtureand not the fluorochemicalproportionalone. CONCLUSIONS The testsubstance 3-hour EC5o foractivatedsludge respiratioinnhibitiownas determined tobe >1000 nig/L. Submitter: 3M Company, EnvironmentalLaboratory,P.O.
