КОНЦЕНТРАЦІЯ МЕТАЛІВ У ТКАНИНАХ ТА МЕТАЛОТІОНЕЇНАХ ВОДНИХ ТВАРИН В ІНДИКАЦІЇ КОМПЛЕКСНОГО ЗАБРУДНЕННЯ ДОВКІЛЛЯ

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.
