Review of toxicity for the main chemical elements - pollutants of salmonid spawning rivers in Kamchatka

Abstract

Toxicological tests of salmons on acute and chronic critical concentrations of 15 chemical elements (Cu, Zn, Pb, Co, Ni, Mn, Sb, Al, Fe, Mo, V, Se, S, As, B) are executed and compared with cited data, with special attention to mechanisms of the toxins physiological effects on fish, including their synergistic and antagonistic influence. These elements are the most common pollutants of spawning rivers in Kamchatka. For better comparability, the standard test object is used, as rainbow trout. Regional amendments to the normative standards of anthropogenic discharges are proposed.
