MICROBIAL INHIBITION (DEHYDROGENASE ACTIVITY TEST)
TEST SUBSTANCE____________________________________________
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 number was not noted. 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 foamer, 1% sodium octyl sulfate, 0.04% sodium lauryl sulfate, 0.5% polyoxyethylene monooctylphenyl ether, and 0.05% benzotriazole.
The following summary applies to a mixture with incompletely characterized concentrations of impurities. Data may not accurately reflect inhibition by the fluorochemical component o f the test sample.
METHOD:____________________________________________________
Method: Not noted. GLP: No Year completed: 1973-1974 Analytical monitoring: % Transmittance Statistical methods: Results were determined by calculation of the % transmittance and comparison with the blank. Test organism source: Not given Contact time: Not given.
RESULTS____________________________________________________
Nominal concentrations: Blank control, 0.01,0.1,0.5, 1,5, and 10% concentration during the study conducted in 2/74. Blank control, 0.1, 0.5, and 1.0% concentration during the studies conducted in 3/73 and 3/74. Element values: Not given.
Remarks: Testing was conducted on the mixture as described in the Test Substance Remarks field. The values reported apply to that mixture and not the fluorochemical proportion alone.
CONCLUSIONS_______________________________________________
No conclusions given.
Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133

DATA QUALITY Reliability: Klimisch ranking 3. Study lacks description and records of the method followed. 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.
