【 摘 要 】

The work evaluates the general distribution of mercury in the soil cover of the Tunkinskaya depression (the Republic of Buryatia, the national park «Tunkinsky»). For this purpose, its gross contents in natural and agrogenically transformed soils were studied: plow lands, fallow lands, hayfields and pastures. The physico-technical characteristics of soils, the content of organic carbon, group composition of humus are determined. The method of processing the results included the calculation of the ecological and geochemical parameters: the concentration coefficient relative to the background, MAC, Clark concentration relative to the Earth's crust, the Earth's soils, the identification of the relationship with the physical and technical characteristics of the soil, and the content of C02, CO2carbonates, fulvic and humic acids.
