Biotransformation of N-Ethyl Perfluorooctanesulfonamide by Rainbow Trout (Onchorhynchus mykiss) Liver Microsomes: Biotransformation of N-Ethyl Perfluorooctanesulfonamide by Rainbow Trout (Onchorhynchus mykiss) Liver Microsomes. Tomy, Gregg T.; Tittlemier, Sheryl A.; Palace, Vince P.; Budakowski, Wes R.; Braekevelt, Eric; Brinkworth, Lyndon; Friesen, Ken ( Department of Fisheries and Oceans, University of Manitoba, Winnipeg, MB R3T 2N6, Can.).

ISSN: 0013-936X. 754-91-6 and 45285-51-6 which are cas registry numbers are also used here. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Rainbow trout (Onchorhynchus mykiss) liver microsomes were incubated with N-Et perfluorooctanesulfonamide [N-EtPFOSA, C8F17SO2NH(C2H5)], to examine the possibility of in vitro biotransformation to perfluorooctane sulfonate (PFOS, C8F17SO3-) and perfluorooctanoate (PFOA, C7F15COO-). Incubations were performed by exposing trout liver microsomes to N-EtPFOSA at 8° in the dark. Reaction mixts. were analyzed after incubation periods of 0, 2, 4, 8, 16, and 30 h for N-EtPFOSA, PFOS, PFOA, and perfluorooctanesulfonamide (PFOSA, C8F17SO2NH2), a suspected intermediate. Amts. of PFOS and PFOSA were found to increase with incubation time, but only background levels of PFOA were detected. Three possible reaction pathways are proposed for the conversion of N-EtPFOSA to PFOS: (i) direct conversion of N-EtPFOSA to PFOS by deethylamination accompanied by conversion of the sulfone group to sulfonate, (ii) deethylation of N-EtPFOSA to PFOSA, followed by deamination to form PFOS, and (iii) direct hydrolysis of N-EtPFOSA. These findings represent the first report indicating a possible biotransformation of a perfluorosulfonamide to PFOS in fish and may help to explain the detection of PFOS, which is relatively involatile, and thus not likely to undergo atm. transport, in biota from remote regions. .

DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) The title compns. forming smooth-surfaced coatings with excellent salt water resistance contain F-contg. surfactants and F-contg. amides RZNR1R2 [R = C4-20-perfluoroalkyl, perfluoroalkenyl; Z = CO, SO2, p-OC6H4CO, p-OC6H4SO2, (CH2)iSO2, (CH2)iCO; R1, R2 = H, C1-20-alkyl, (CH2CH2O)mR3, (CH2CHMeO)nR3; R3 = H, C1-6-alkyl; i = 1-8; m, n = 1-20]. Thus, a 0.01% methanolic soln. 2395-00-8 and 754-91-6 are just another two chemicals used in this study. of mixt. of C6F13SO3K [3871-99-6] and C6F13SO2NH2 [41997-13-1] was coated on glass and dried for 3 min to give a smooth-surfaced coating with decane contact angle 82°. The same soln. was coated on steel and dried for 3 min to give a coating with salt water resistance >5 h. .
