THE CONTENT OF CHEMICAL ELEMENTS IN THE ORGANS OF THREE TYPES OF MARINE FISH

Abstract

The concentrations of 24 elements were investigated in the organs and tissues of commercial fish species – pollock, cod and scomber from fishing zones of Far Eastern region. The levels of element concentration in fish are changed greatly in several orders of magnitude, reflecting it content in the environment from the one side, and it’s role in biochemical processes from the other side, providing vital functions and survival of fish. The liver accumulates maximal concentrations of most elements, the muscle tissues are distinguished by relatively low content of elements. The average concentrations of toxic elements As, Cd, Hg, Pb don’t exceed it’s maximal permissible levels of concentration.
