ANALYSIS OF HYDROCHEMICAL STABILITY OF LIMNOSYSTEMS OF LAKES IN SHATURSKY DISTRICT
Abstract
Susceptibility of limnosystems to the influence
of pollutants is mainly determined by the physicochemical
processes occurring between waters of lakes and sediments
composing the lake kettles and catchment basins. By analyzing
the geological structure of the lake area in Shatursky
district, the factors contributing to the stability of hydrochemical
parameters of the lakes are identified and assessed.
The main factors include the increased capacity of bottom
sediments (sapropels) to absorb heavy metals and petroleum
products, as well as the close chemical interaction of lake waters
and underground waters of the surrounding peat bogs.
Due to technogenic humification of the peats near the lakes
in Shatursky district and to thermal eutrophication of their
waters, a decrease in geochemical security of the catchment
basins and a change in hydrochemical conditions of the lakes
are predicted.
