Геохимия ландшафтов г. Улан-Батора

On the basis of geochemical surveys of 2008–2010, differentiated assessment of heavy metal contamination (As, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sr, V and Zn) of snow cover, soil and woody plants by functional zones of Ulan Bator is given. Regional specialization of depositing sources and their technogenic geochemical transformation in the city are measured. The factors that control the accumulation of pollutants in the landscape are singled out. The spatial distribution of heavy metals in soils and leaves of poplar is analyzed. On the basis of ecological and geochemical evaluation of the snow cover, soil and trees, the pollution of urban landscape as a whole is characterized as weak. Contamination of functional zones decreases from industrial to transportation, residential and recreational zone.
