Abstract
The enantiomeric ratios of alpha-HCH were determined by chiral gas chr omatography in blubber of marine mammals from regions of the northern hemisphere (North Sea, Baltic Sea, Arctic, and Iceland). Cetaceans (ha rbour porpoises and white-beaked dolphins) showed a preferential accum ulation of (+)-alpha-HCH. In blubber of harbour seals, grey seals and harp seals (+)-alpha-HCH was also more abundant than (-)-alpha-HCH. Ho oded seals formed an exception with a (+/-) enantiomeric ratio of alph a-HCH < 1.
