摘要：

The present study aimed to assess the biotransport of POPs, including OCPs and PCBs, by Pacific salmon (genus Oncorhynchus) on the northwestern Pacific Ocean. In 2008-2012, the Amur River basin, the eastern Kamchatka, and the mainland coast of the Sea of Okhotsk received the largest amounts of pesticides. In 2018, the transport of OCPs to the Russian northwestern Pacific reached only 1 kg, and the total OCP levels in muscles of fish from this region were significantly lower than in previous years. The average concentration of PCBs for all species under study differed from that of OCPs, with the highest concentration recorded from sockeye salmon. In 2018, pink salmon brought the largest amount of PCBs to the Russian northwestern Pacific. Coastal water pollution has decreased significantly in recent years due to the ban on the use of POPs in the Northwest Pacific (according to the measurements in 2010 and 2018).
