A R 30 - o w a 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-127. Current information indicates it is a mixture of 40-44% test substance, 32% water, 14% isopropanol, 4% ethanol, and 6-10% C 4 -C 7 fluoroalkyl carboxylate compounds. 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 BOD with Dichromate reflux determination of COD GLP: No Year completed: 1982 Contact time: 20 days Innoculum: Not noted RESULTS Chemical Oxygen Demand: 415,000 mg 0 2 / kg chemical (mean value) Biochemical Oxygen Demand: 5-Day: 240,000 mg/L 10-Day: 310,000 mg/L 20-Day: 320,000 mg/L Remarks: Testing was conducted on the mixture of the test substance as described in the test substance remarks field. The values reported apply to that mixture and not the test substance. The BOD and COD values are expected to be the result of biodegradation / oxidation of the organic solvent components, but it's not understood what portion of the degradation can be attributed to the Perfluorooctanesulfonylamido(ethyl)acetate. CONCLUSIONS 000^14 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. Testing cannot conclude what portions of the test sample were responsible for the apparent biodegradation values. The analytical method is not chemical specific.
