ARX-OW BIODEGRADATION TEST SUBSTANCE Identity: Perfluorooctanesulfonylamido(ethyl)acetate; may also be referred to as PFOSAA, FC-128 or as the major component of FC-127, FC-129, FC-109, orFC-109-X. (Glycine, N-ethyl-N[(heptadecafluorooctyl)sulfonyl]-, potassium salt, CAS # 2 9 9 1 51-7) Remarks: The test sample is FC-109-X. Current information indicates it is a mixture of 19-23% test substance, 61% water, 12% 2methoxymethylethoxypropanol, 2% ethanol, and 2-6% C 4 -C 7 fluoroalkyl carboxylate compounds. Test sample was from 3M production lot 2. The following summary is abbreviated because the test sample is a mixture of the test substance in a water/organic solvent solution. Data will not accurately relate biodegradation of the test sample with that of the test substance. METHOD: Method: Not noted. Type: Aerobic Carbonaceous BOD with Dichromate reflux determination of COD GLP: No Year completed: 1987 Contact time: 20 days Innoculum: Not noted RESULTS Chemical Oxygen Demand: 375,000 mg O2 / kg product Biochemical Oxygen Demand: 5-Day: 31,000 mg/L 10-Day: 61,000 mg/L 20-Day: 69,000 mg/L Remarks: The BOD and COD values are expected to be the result of biodegradation of the organic solvent components of the test sample. These values are not expected to be representative of the Perfluorooctanesulfonylamido(ethyl)acetate. CONCLUSIONS OOO 2,30 This testing indicated that some portion of the test sample biodegraded in aerobic environments capable of supporting biodegradation. Submitter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY Reliability: Klimisch ranking 3. This study lacks information on the methodology, characterization of the test substance purity and analytical measurement of test concentrations. Testing cannot conclude what portions of the test sample were responsible for the apparent biodegradation values.
