ACTIVATED SLUDGE RESPIRATION INHIBITION 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, or FC-109-X. (Glycine, N-ethyl-N[(heptadecafluorooctyl)sulfonyl]-, potassium salt, CAS # 299151-7) 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% C4-C7 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 may not accurately relate toxicity of the test sample with that of the test substance. METHOD: Methods: Protocol Reference EAR, 11/8/79. Test type: Not noted. GLP: No Year Completed: 1981 Test organism source: Activated Sludge mixed liquor from St. Paul, Minnesota Metro Wastewater Treatment Plant RESULTS Nominal concentrations: Bk control, 1000 mg/L Element values: No acute inhibitory effect on activated sludge respiration rate at 1000 mg/L with a contact time of 3.25 minutes. Remarks: Testing was conducted on the mixture of the test substance as described in the test substance remarks field. The value reported applies to that mixture and not the test substance. No attempt was made to determine the impact of the presence of the organic solvents or what portion of the toxicity can be contributed to the Perfluorooctanesulfonylamido(ethyl)acetate. CONCLUSIONS Limited contact time estimates that FC-127 is not expected to inhibit the activity of activated sludge. 000221 Submitter: 3M Company, Environmental Laboratory, P.O.
