Abstract
The concentration of organochlorine pesticides in pink salmon Oncorhynchus gorbusha and chum salmon O. keta has been studied for the fish sampled in the Sea of Okhotsk and along the Pacific coast of the Kuril Islands during the spawning migrations. Chum salmon accumulates much more pollutants (180 ng/g of wet weight) than pink salmon does (70 ng/g of wet weight). The total bulk of the toxicants transported by the Pacific salmon to the Russian coast of the northwestern Pacific Ocean in 2008–2010 ranged between 13.0–35.5 kg in regard to the number of the breeders reached the spawning grounds. The ecological risk for the local spawning grounds is discussed.
