ACTIVATED SLUDGE RESPIRATION INHIBITION TEST TEST SUBSTANCE Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may also be referredtoas PFOS, FC-95, or as a component ofFC-600. (1-Octanesulfonicacid,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-p,otassium salt,CAS # 2795-39-3) Remarks: The 3M productionlotnumber was 628. The testsample is FC-600. Currentinformationindicatesitisa mixtureof 1.0% PFOS, 81.20% water,12.00% diethyleneglycolbutylether,1.00% sodium octyl sulfate2,.00% propane Sultonefoamer, 1.00% sodium decylsulfate, 0.85% xanthangum, 0.1% N-(3-chloroallyhie)xaminium chiodde,0.80% starch,and 0.05 % benzotriazole. The followingsummary applies to a mixture with incompletely characterizedconcentration of impurities.Data may not accurately reflectthe the inhibitionby the fluorochemical component of the test sample.
