Levels of alpha-HCH, lindane, and enantiomeric ratios of alpha-HCH in marine mammals from the northern hemisphere.
The enantiomeric ratios of alpha-HCH were determined by chiral gas chromatography in blubber of marine mammals from regions of the northern hemisphere (North Sea, Baltic Sea, Arctic and Iceland). Cetaceans (harbour porpoises and white-beaked dolphins) showed a preferential accumulation of (+)-alpha-HCH. In blubber of harbour seals, grey seals and harp seals (+)-alpha-HCH was also more abundant than (-)-alpha-HCH. Hooded seals formed an exception with a (+/-) enantiomeric ratio of alpha-HCH < 1.
