Desertification and pollution of heavy metals in urban areas (by the example of the Republic of Buryatia Zakamensk)

Discusses environmental problems of urban areas on the example of the Republic of Buryatia Zakamensk. Urboopustynivanie is linked to chemical pollution, sandy tehnojeljuvija, distribution of pollutants in water and wind flow across a wide perimeter. Identify indicators loads on the investigated territory. To calculate erosion tehnojeljuvija with levels applied universal equation USLE and deflationary contamination was calculated on the basis of known position that the kinetic energy of the wind is directly proportional to the cube of its speed and back proportional to the square of the soil moisture. Quantitative parameters obtained pollution urbozemov Zakamensk priority metals as Cd, Pb, Zn, Cu, as well as Mo and W. Obtained that erosive loss contaminated sands range from 6.7 to 28.8 t/ha/year, and deflationary loss reach 10 t/ha/ year. While urbojekosistemu only with water jets, only mercury and only from 1996 (closing time of the plant) is horrible around 155 t. Taking into account deflationary to increase this quantity pollution in 2 times.
