Abstract
The lakes of “Kokshetau” State National Natural Park (SNNP) are scanty and have a mosaic, fragmented character due to the present ecological state. In current work, the chemistry and degree of pollution in this lake is studied. The present research aimed to analyse the hydrophysical and hydrochemical parameters of lake Imantau of “Kokshetau” SNNP. This assessment includes dynamics of the hydrochemical water composition and benthal deposits, heavy metals content, and morphometric indicators of the lake using Earth’s remote sensing technique. This technique is based on Earth’s retrospective multichannel satellite images Landsat. Ionic water composition, total mineralization, hydrogen index, gas regime, and nutrient content (nitrates, nitrites) are determined. To assess the geochemical state of benthal deposits, the parameters like concentration coefficient (Cc), maximum allowable concentration (MAC) of pollutants in the soil, and total pollution index (Zc) are calculated. The results of this work is measured in terms of changes takes place in lake depth, water mass volume, water hardness, chemical concentrations.
