Eutrophication of lakes in Volyn region

Abstract

The article describes the state of eutrophication of water bodies of Ukrainian Polissya on the example of some lakes of Turiysk region. It is indicated legislation defining the notion of eutrophication. It is displayed water fund of Volyn region in terms of surface water bodies — lakes, reservoirs and ponds. It is specified the results of studies on overgrowing and water logging of water bodies. It is separately marked the natural conditions of the lakes of Turiysk territory and their impact on the surrounding area. It is considered the newly approaches of national legislation on the environmental state of water bodies or their parts that allows to estimate consequences of eutrophication on a comparison of environmental standards for water quality of surface water bodies. It is analyzed the accumulation of bottom sediments in water bodies with atmospheric and marsh nutrition type. It is calculated the dynamics of change of water surface area of eleven lakes of Turiysk region for assessing the degree and forecast of their eutrophication. It is conducted the estimation of anthropogenicchanges that have occurred over the last 80 years and proposed environment protection measures for restoration of functioning of anthropogenically modified ecosystem « lake — floodplain» in order to preserve their water content
