Abstract
Heavy metal concentrations were studied in aquatic organisms (mollusks and higher aquatic plants) and bottom sediments of lakes Blagodati, Vas’kovskoe (Primorskii krai) and Azabach’e (Kamchatskii krai). The geochemical features of watershed rocks, including higher total and leachable concentrations of microelements in bottom sediments (Cu and Ni in Lake Azabach’e, Zn and Pb in Lake Vas’kovskoe) correlate with higher concentrations of those elements in aquatic organisms. Lake Blagodati, where metal concentrations in the sediments are minimal, can be taken as background for Primorskii krai.
