Abstract

The dynamics of metal concentrations in the solution, suspension, sediments, and floating plants, as well as functional and structural parameters of phytoplankton and zooplankton were studied. The sorption rate of metals on suspension and the efficiency of their removal into bottom sediments decreased in the series Pb > Cu > Zn > Cd and at increasing proportion of metal aquaions in the solution. The effect of intensive renascence of green algae was recorded from the eighth to tenth day after the metal discharge into the mesocosms. This effect activated a plankton mechanism of metal removal into bottom sediments. The metal discharge led to a strong and stable depression in all groups of zooplankton. © 2004 MAIK "Nauka/Interperiodica".
