17 fat tissue samples of four different Arctic seals species shot in Greenland, fat samples of one polar bear, two polar foxes and one sheep from south west Greenland were assayed for polychlorinated hydrocarbons (PCHC), aldrin, heptachlor, heptachlorepoxide, lindane, “raw” DDE and PCB.
“Raw” pp 'DDE and PCB were found in all specimens in highest amount, peak values of pp 'DDE were found in the polar bear and highest amount of PCB was found in a hooded seal.
Aldrin was also found in most samples, but only trace amounts of lindane, heptachlor and its epoxide were found variably. In PCHC content great variation from specimen to specimen was found in all species.
The data obtained are discussed in relationship to the possible sources of PCHC contamination of the Arctic.
