ACTIVATED SLUDGE RESPIRATION INHIBITION TEST * -z' TEST SUBSTANCE Identity: Periluorooctanesulfonate, DEA salt; may also be referred to as PFOS DEA salt, FC-99, or 3M Sample No. 2. (1-Octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, compd. with 2,2'-iminobis[ethanol] (1:1), CAS # 70225-14-8) Remarks: Test sample is a mixture of the test substance in water (approximately 25% test substance and 75% water). All values reported relate to this mixture. No calculations were made to adjust for the actual concentration of the test substance in the test sample. METHOD Method: Not noted. Test type: Static acute GLP: No Year Completed: 1979 Analytical m onitoring: DO concentrations. Method Remarks: Testing was terminated when there was no indication of toxicity at the highest sample concentration. RESULTS__________________________________________ Nominal concentrations: 1000 mg/L test material solution. Control response: Unknown Remarks: Testing was conducted on the "as-sold" mixture of the subject material (25% subject substance in water). The value reported applies to that mixture and not the test material. CONCLUSIONS______________________________________________ The test material exhibited no inhibitory effect at 1000 mg/L over a 7minute exposure. Subm itter: 3M Company, Environmental Laboratory, P.O. Box 33331, St. Paul, Minnesota, 55133 DATA QUALITY_______________ 001592 R eliability: Klimisch ranking 3. This study lacks sufficient documentation, characterization of the test substance purity, and analytical measurement of test concentrations. Additionally, testing was conducted on the "as sold" product, and testing was discontinued at 1000 mg/L.
