Abstract


The present study aimed to compare the ability of bivalve mollusks and fish to accumulate some toxic metals in their tissues in the polluted environment. Populations of Dreissena polymorpha, Unio tumidus and Carassius gibelio in Latvia in Ukraine were investigated. In the mollusks from the polluted reservoirs, the accumulation of Zn, Cu, Cd in the tissues but decrease in metallothioneins concentration was detected, whereas the fish did not appropriate reflect the aquatic quality.

Keywords


etallothioneins; bivalve mollusks; fisch, copper; zinc; cadmium; bioindicatson
