BIODEGRADATION TEST SUBSTANCE Identity: N-Ethylperfluorooctanesulfonamide; may also be referred to as U1464, EtFOSA, EtPOSA, F-6309, or FX-12. (1Octanesulfonamide, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadecafluoro-N-ethyl-, CAS # 4151-50-2) Remarks: Material is a white solid. Sample purity and lot number were not recorded. The report with supporting information could not be located for this study. What is summarized is the computer print-out reporting final results. METHOD Method: Not noted. Type: Aerobic GLP: No Year completed: 1984 Test solution preparation: A solubilizing agent, FX-3250 was used to dissolve the test substance in the BOD medium. This agent is mixture of perfluorinated carbon chains (C5-C18). Other studies were reported under the same study number measuring COD with and without the presence of the solubilizing agent. Contact time: 20 days Inoculum: Not noted RESULTS 5-day BOD: 10-day BOD: 20-day BOD: COD: < 940 mg/kg < 960 mg/kg < 940 mg/kg 22,000 mg/kg CONCLUSIONS This testing indicated that the test substance is not capable of readily biodegrading in aerobic environments. 006035 DATA QUALITY Reliability: Klimisch ranking 4. Summary was created using only a listing of test values. The original study procedure and raw data were not found.

RATHER THAN USING ACETONE AGAIN TO SOLUBILIZE THE FX-12 FOR BOD DETERMINATIONS USE FX-3250 A COMMERCIAL CHEMICAL DIV. MATERIAL AS THE SOLUBILIZING AGENT. COD-RFX FOR SAMPLES 1, 2 AND 3 WAS RUN ON SAMPLES AFTER SOLVENT WAS DRIVEN OFF WITH NITROGEN. COD-RFX FOR SAMPLES 4, 5 AND 8 WAS RUN WITHOUT EVAPORATION OF SOLVENT. SAMPLES 6 AND 7 WERE RUN WITHOUT ANY FX-3250.
