Abstract The study is devoted to the microelement composition of organs and tissues of chum salmon (Oncorhynchus keta), which came for spawning in September 2018 in the r. Lovetskaya on the southwestern coast of Sakhalin. Samples of organs and tissues of fish, prepared in Sakhalin, were frozen and delivered to Vladivostok for chemical analysis. Trace elements were determined from acid mineralizates by atomic absorption on a Shimadzu AA 6800. It was found that the content of microelements indicating anthropogenic impact on the environment (Zn, Cu and Ni) in the Sea of Japan chum was significantly higher than the content of those in the Okhotsk Sea fish. So, for example, the amount of zinc in the muscles of the Sea of Japan chum salmon was 2.5 times higher than in those of the Sea of Okhotsk fish. In the liver, the effect was even greater - the difference between the content of this element in the Sea of Japan and the Sea of Okhotsk reached 19 times. At the same time, in the organs and tissues of the Okhotsk chum salmon, which crossed the impact geochemical zone in the Kuril-Kamchatka region at least twice during its life cycle, the content of lead and cadmium, witnesses of underwater and surface volcanism in the Kuril straits, prevailed. The content of lead in the muscles of chum salmon from r. Raidovaya was 4 times more than in the muscles of chum salmon from the river. Lovetskaya; in the liver, the difference was 5 times.
