ACTIVATED SLUDGE RESPIRATION INHIBITION TEST SUBSTANCE Identity:Perfluorooctanesulfonylamido(ethyl)acemtaaytea;lso be referredtoas PFOSAA, FC-128 oras themajor component of FC-1 27, FC-129, FC-1 09,or FC-109-X. (Glycine,N-ethyl-N[(heptadecafluorooctyl)sulfonpyolt]a-s,siumsalt,CAS # 2991 51-7) Remarks: The testsample isFC-127. Currentinformatioinndicateist isa mixtureof40-44% testsubstance,32% water,14% isopropanol4,% ethanol,and 6-10% C4-C7 fluoroalkyclarboxylatecompounds. The followingsummary isabbreviated because the testsample isa mixture of the testsubstance in a waterlorgank solventsolution. Data may not accuratelyrelatetoxicityof the testsample with thatof the testsubstance. METHOD: Methods: ProtocolReference EAR, 11/8/79. Test type:Not noted. GLP: No Year Completed: 1981 Test organism source:ActivatedSludge mixed liquofrrom St.Paul, 'MinnesotaMetro Wastewater Treatment Plant RESULTS Nominal concentrations: Bk control,1000 mg/L Element values: No acute inhibitoreyffecton activatedsludge respiratiornateat 1000 mg/L witha contacttime of 3.25 minutes. Remarks: Testingwas conducted on the mixtureofthe testsubstance as describedinthe testsubstance remarks field.The valuereportedapplies tothatmixtureand not thetestsubstance. No attemptwas made to determinethe impact ofthepresence oftheorganicsolventsorwhat portionofthe toxicitcyan be contributedtothe Perfluorooctanesuffonylamido(ethyl)acetate.
