: AR R26 -- O776 BIODEGRADATION (BOD/COD) IESTs0u 000B 000 sTANCE Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95,or as a component of FC-206 or L3243. (1-Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot numbers were 510 and 512. The test sample is FC-206. Current information indicates it is a mixture of 0.67% PFOS, 17.5% diethylene glycol butyl ether, 78.91% water, 1.33% Sultone fpoolaymoexry,e1th%ylseondeimuomnoocotcytlysluplfhaetney,l0e.t0h4er%, saonddiu0m.0l5au%ryblensuzloftartiea,z0ol.e5.% The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data does not accurately reflect degradation potential of the fluorochemical component of the test sample. M0 eTHo0 o: 00000000000 Method: Not noted.

Box 33331, St. Paul, Minnesota, 55133 p0 ataQuaury0000 Reliability: Klimisch ranking 3. Study lacks description and records of the method followed. Additionally, the study was terminated prematurely due to incubation difficulties. The inoculum is not properly characterized. The `sample purity was not properly characterized and the study lacks analytical confirmation of the amount of fluorochemical proportion in the solution.
