Hydrothermal regime of the urban soils in the cold period of the hydrological year of Western Siberia (Russia).

This study analysed the temperature and humidity properties of urban soils in the territory of the Mikhailovskaya Embankment Park of Culture and Recreation in Novosibirsk, Russian Federation, in the cold period of the 2018-2019 hydrological year. Data on the temperature of the air and soil at various depths, winter and spring soil moisture and data on the dynamics of snow accumulation and snow distribution were analysed. This study found that, despite high levels of humidity in the autumn and the high snow reserves that accumulated during the winter, a decrease in soil moisture content was observed after the snow had melted.

Hg in snow cover and snowmelt waters in high-sulfide tailing regions (Ursk tailing dump site, Kemerovo region, Russia).

Gold-bearing polymetallic Cu-Zn deposits of sulphur-pyrite ores were discovered in the Novo-Ursk region in the 1930s. The average content of mercury (Hg) was approximately 120 μg/g at the time. A comprehensive study of Hg distribution in waste of metal ore enrichment industry was carried out in the cold season on the tailing dump site and in adjacent areas.
