Abstract

Polychlorinated biphenyls (PCBs), oxychlordane, DDT and its metabolites, hexachlorobenzene (HCB), hexachlorocyclohexanes (HCHs), and compounds of technical toxaphene (CTTs) were quantified by gas chromatography and electron capture detection in livers of ten arctic foxes and in liver and adipose tissue of a polar bear. Enantiomeric ratios of oxychlordane and other chiral organochlorines were determined after gas chromatographic enantioseparation on two chiral stationary phases. The organochlorine patterns of the livers of arctic foxes was dominated by oxychlordane, while PCB congeners and other organochlorines were only lowly abundant. Livers and adipose tissue of the bear showed deviating level and ratios of the contaminants.
