Levels of polychlorinated dibenzo-p-dioxins (PCDD), dibenzofurans (PCDF) and pesticides in ringed seal blubber have been reported in Chemosphere 17 , 1291 (1988). Additional informations about sex, age and exact area which had gone lost by accident, have now been regained. They made a re-evaluation of the data necessary since the animals were caught much closer to the settlement at Ny Alesund than assumed earlier. No influence of this local source on the determined concentrations was found when they were compared with the levels in Arctic seals which have been published in the meantime. |
