The ecological-hydrochemical condition of the Ryazan Meshchera lakes

Identifies the main hydro-chemical parameters of some lakes of the Ryazan Meshchera, including lakes Laskowski, located in the immediate vicinity of the centre. All lakes are of glacial origin and were formed in specific environmental and geochemical conditions of Polesie landscapes. They are characterized by widespread fluvioglacial and ancient alluvial sand deposits, a kind of combination of coniferous forests with marshy areas, a relatively small anthropogenic load. The research established that extremely low TDS water of all lakes, and respectively detected very small concentrations of major macro - and micronutrients. Against this background, a large presence of iron in lake water, which is related to the geochemical background. The signs of pollution, including domestic sewage, in the studied lakes was not detected.
