BIODEGRADATION (BOD/COD)
TEST SUBSTANCE
Identity:A mixturecontainingperfluorooctanesulfonatweh,ich may alsobe referredto as PFOS, FC-95 or as a component ofFC-201 AF. (1Octanesulfoniaccid)(CAS # 2795-39-3).
Remarks: The 3M producton lotnumber was not noted. The testsample isFC-201AF. Currentinformationindicatesitisa mixtureof3% PFOS, 18.59% diethyleneglycolbutylether,37.81% water,14% ethyleneglycol, 8.25% Acrylicfoanier,9% sodium oetylsulfate0,.3% sodium laurylsulfate, 3% triethanolamine6,% sulfonatedalkylethersalts,and 0.05% tolyltriazole.
The followingsummary applies to a mixture with incompletely characterizedconcentrations of impurities.Data may not accurately reflectthe biodegradabilityof the fluorochemical component of the test sample.
