Abstract

The content of individual metals in carp, crucian carp, perch and pike tissues from small rivers of Western Podillya is investigated. It is shown, that for different metals there are individual patterns of accumulation in different tissues of the organism. However, the general tendencies that determine cellular transformations in fish are: tissue-specific cell localization, due to their morphology, chemical composition and membrane activity; chemical activity of metal ion, especially complexing ability with proteins and low molecular weight metabolites; concentration of ions, which affects the total ionic homeostasis in the organism. The maximum level of accumulation of the Mangan, Ferum and Copper in the tissues of fishes from Strypa, Cobalt, and Zinc in the tissues of fishes from Seret river is noted. In the Zolota Lypa river, in the vast majority of cases, accumulation of the minimum amount of metals in tissues of investigated species of fish took place, which may be due to the low bioavailability of metals for both predatory fish and benthophages.Pollution of internal reservoirs, including fishing, is one of the limiting factors for the functioning of aquatic ecosystems and their bioproductivity. The study of physiological and biochemical mechanisms of accumulation and distribution of metals in fish tissues under conditions of contamination of water ecosystems is one of the main conditions for the development of effective means of increasing the organism's resistance to new conditions of existence.
