BIODEGRADATION TEST SUBSTANCE Identity: N-Ethylperfluorooctanesulfonamidmea;y also be referredto as U1464, ETFOSA, ETPOSA, F-6309,or FX-12. (1Octanesulfonamide,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8heptadec,afluoro-N-ethyClA-S, # 4151-50-2) Remarks: Materialisa white solid.Sample purityand lotnumber were not recorded.

Type: Aerobic GLP: No Year completed: 1984 Test solutionpreparation:A solubilizianggent,FX-3250 was used to dissolvethetestsubstance inthe BOD medium. This agent ismixtureof perfluorinatecdarbon chains(C5-Cl8).Otherstudieswere reportedunder the same study number measuring COD withand withoutthe presence of the solubiliziangent. Contact time:20 days lnoculum: Not noted RESULTS 5-day BOD: 10-day BOD: 20-day BOD: COD: < 940 mg/kg < 960 mgfkg < 940 mg/kg 22,000 mg/kg CONCLUSIONS This testingindicatedthatthe testsubstance isnotcapable ofreadily biodegradinginaerobicenvironments. .DATA QUALITY Reliability:Klimischranking4.

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. GOD-RFX FOR SAMPLES 1, 2 AND 3 WAS RUN ON SAMPLES AFTER SOLVENT WAS DRIVEN OFF WITH NITROGEN. GOD-RFX FOR SAMPLES 4, 5 AND 8 WAS RUN WITHOUT EVAPORATION OF SOLVENT. SAMPLES 6 AND 7 WERE RUN WITHOUT ANY FX-3250. -------------------------------------------------------------------------------- SAMPLE DATE CODE DESCRIPTION RESULT MDL or (95% C.I.) -------------------------------------------------------------------------------- 1 C-BOD-05 C-BOD-10 C-BOD-20 COD-RFX 2 C-BOD-05 C-BOD-10 C-BOD-20 COD-RFX 3 C-BOD-05 C-BOD-10 C-BOD-20 COD-RFX 4 COD-RFX 5 GOD-RFX 6 COD-RFX 7 COD-RFX W/O FX-3250 BOD-05 (CARBONACEOUS) BOD-10 (CARBONACEOUS) BOD-20 (CARBONACEOUS) COD (DICHROMATE REFLUX) COATED WITH FX-3250 BOD-05 (CARBONACEOUS) BOD-10 (CARBONACEOUS) BOD-20 (CARBONAGEOUS) COD (DICHROMATE REFLUX) 5MLRES FX-3250 BOD-05 (CARBONACEOUS) BOD-10 (CARBONACEOUS) BOD-20 (CARBONACEOUS) COD (DICHROMATE REFLUX) 0.5 G W/FX-3250 COD (DICHROMATE REFLUX) DUP 4 COD (DICHROMATE REFLUX) 0.5 G W/O FX-3250 GOD (DICHROMATE REFLUX) DUP 6 COD (DICHROMATE REFLUX) NOT ANALYZED NOT ANALYZED NOT ANALYZED 17000 MG/KG <940 MG/KG <960 MGIKG <940 MG/KG 22000 MG/KG NOT ANALYZED NOT ANALYZED NOT ANALYZED 41 MG/L 3900 MG/L 3400 MG/L 24000 MG/KG 23000 MG/KG 05/16/2000 ENVIRONMENTAL LABORATORY 2 ARCHLVED FINAL REPORT LAB REQUEST NO.
