INFLUENCE OF THE PILEUP AND MIXING OF WATER ON THE CONCENTRATION OF BIOGENIC ELEMENTS IN THE LITTORAL ZONE OF THE EUTROPHIC LAKE
Abstract
The influence of the pileup and mixing of water on the concentration of dissolved nitrate nitrogen, ammonium nitrogen, and phosphorus in the littoral zone of eutrophic Lake Obsterno (Belarus) has been studied.
This concentration was determined for the two types of the littoral zone – with and without water-air vegetation (Scirpus lacustris). After the pileup the concentrations of PO4–, NO3–, NH4+ ions increased. The increasing of PO4– was higher in the littoral zone without vegetation, but NH4+ – in the littoral with vegetation.
Thus, the pileup and mixing of water in the littoral zone lead to an increase in biogenic elements, which may influence the phytoplankton development.
