Abstract

Acidotrophic lakes are unique reservoirs for the territory of Belarus, which are characterised by a minimum concentration of dissolved substances. They are very sensitive to changes in natural and climatic conditions in watersheds and anthropogenic transformation of water, hydrochemical and thermal regimes, but at the same time they react rather weakly to restoration measures. Lakes of this type are habitats for rare and protected species of flora and fauna. The study of the current state of acidotrophic lakes will make it possible to identify emerging trends in eutrophication at an early stage and to take measures aimed at preventing the degradation of these limnosystems and the disappearance of protected species of aquaflora. The purpose of the study is the analysis of hydrochemical regime of acidotrophic lakes in Belarus under the conditions of climate change and anthropogenic impact on their watersheds. An analysis of the hydrochemical parameters of eight acidotrophic lakes in Belarus showed that, compared with the late 1970s – early 1980s there was an increase in water mineralisation, ammonium ion concentration, a decrease in the concentration of dissolved oxygen and transparency. In the lakes Svityaz and Beloe (Luninets district), a hydrogen sulfide zone forms near the bottom in summer. This testifies to the deterioration of the ecological state of acidotrophic lakes. The results of the study can be used for the management of aquatic ecosystems, during their restoration, optimisation of the economic use of lake catchment areas, in the educational process in the training of hydrometeorologists and geoecologists.
