Summary:
The study of the anthropogenic impact on the environment is one of the most important problems of our time. In the Southern Urals there are many plants of ferrous and non-ferrous metallurgy, machine building, and there is a developed transport network. Investigating landscapes under the influence of the Karabash copper smelter, and comparing it with the conditionally background territory of the Ilmen State Reserve, we found that the migration of heavy metals significantly increases in the impact zone. The value of heavy metals, strongly connected with dust particles, sharply increases by 10-100 orders of magnitude. As a result, active accumulation of pollutant elements occurs in landscapes. The bulk accumulates in the soil. At the same time, the capacity of the biological circulation of metals is greatly increased: Fe is 3 times, Mn is 4-8 times, Ni is 10-14 times, Zn is 40-100 times, Cu is 50-200 times, Pb is 100-400 times, Cd is 1000-3000 times.

Keywords: atmospheric transport, biological circulation, heavy metals, landscape, sources of pollution
