AR AA6 _ OZ Hi BIODEGRADATION (BOD/COD) TEST SUBSTANCE Identity: A mixture containing perfluorooctanesulfonate, which may also be referred to as PFOS, FC-95, or as a component of FC-602. (1Octanesulfonic acid) (CAS # 2795-39-3). Remarks: The 3M production lot number was 501. The test sample is FC602. Current information indicates it is a mixture of 1% PFOS, 12% diethylene glycol butyl ether, 61.05% water, 20% ethylene glycol, 2% Sultone foamer, 1% sodium octyl sulfate, 1% sodium decyl sulfate, 1% magnesium sulfate, 0.7% xanthan gum, 0.1% starch, 0.1% n-(3-chloroallyl)hexaminium chloride, and 0.05% tolytriazole. The following summary applies to a mixture with incompletely characterized concentrations o f impurities. Data may not accurately reflect the biodegradability of the fiuorochemicai component o f the test sample. METHOD:________________________________________________________ Method: Standard Methods, 507 for BOD and 508 for COD.

Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY__________________________________________________ 002106 Reliability: Klimisch ranking 2. Testing meets criteria for quality testing. However, the seed source was not indicated. There is a lack of characterization of sample purity and the study lacks analytical confirmation of the amount of fluorochemical proportion in the test solutions.
