T. Ellerichmann et al., GAS-CHROMATOGRAPHIC ENANTIOMER SEPARATIONS OF CHIRAL PCB METHYL SULFONS AND IDENTIFICATION OF SELECTIVELY RETAINED ENANTIOMERS IN HUMAN LIVER, Fresenius environmental bulletin, 7(5-6), 1998, pp. 244-257
The enantiomers of eight atropisomeric PCB methyl sulfons were separat
ed by chiral capillary gas chromatography, using a modified cyclodextr
in as stationary phase. Two of these PCB derivatives, -methylsulfonyl-
2,2',3',4',5,6-hexachloro-biphenyl (3-132) and 3-methylsulfonyl-2,2',4
',5,5',6-hexachlorobiphenyl (3-149), were detected in human liver samp
les and showed high enantiomeric excesses. In addition, 3-methylsulfon
yl-4,4'-DDE (MeSO2-DDE) and bis(4-chlorophenyl)sulfone (BCPS), were pr
esent in human liver.
