Abstract
Role of mineral suspended particles and the intensity of plankton reproduction in the sedimentation processes of the removal of Cu, Pb and Cd from water in a polluted water reservoir were studied by means of mesomodelling. Under the action of metals, the structure of the natural phytoplankton community gets rearranged, which leads to gradual increase in the total number of organisms and an increase in their fraction in settling sediments. This is accompanied by an increase in the concentrations of metals in sediments, likely due to the higher biosorption in comparison with metal sorption on mineral suspended particles.
