Characteristics of Bioaccumulation of Elements in Organs and Tissues of Fish during Stabilization of Anthropogenic Load: Evidence from Whitefish Coregonus lavaretus L. of Subractic Lake Imandra

Abstract

Abstract—This paper considers the bioaccumulation of elements in organs and tissues of whitefish from the Lake Imandra reaches, which were subjected to different anthropogenic impacts, during stabilization of anthropogenic load. It is shown that the element accumulation in the organs and tissues of the whitefish is mainly controlled by the individual resistance to the higher concentrations of toxic elements and physiological state rather than by their concentrations in water. The models of element redistribution in liver and kidney depending on the physiological state of the fish are constructed. Changes in iron and zinc metabolism at different concentrations of hemoglobin in blood and stages of fish disease are shown.
