Our synthesis of the published scientific literature shows complexity and diversity of environmental effects of urbanization on the natural components and ecological systems: excessive loads on the lithosphere of the city and its surface manifest; The consequences of water use in the city; consequences of atmospheric pool pollution by city transport and plants there are acid precipitation; «heat islands»; dust content of the atmosphere and climate change; impact associated with the load on the landscape; alienation of land for waste dumps; the effects of electromagnetic radiation, noise, vibration, light and information pollution of the environment.

It was determined that the soil cover of the river valley is characterized by a significant transformation of basic chemical, physical-chemical properties of soil and humus condition that affects the main areas and the intensity of the geochemical migration of chemical elements. In the river valley Lopan there are signs formation of a new man-made physical-chemical alkaline geochemical barrier in superaqual and eluvial-accumulative landscapes (floodplain and floodplain terraces r.Lopan), which contributes to the intensification of surface accumulation of chemical elements and braking processes of vertical and horizontal migration. It is established that the most of the investigated valley alkalinization urban soil surface layer reduces the migration ability of various contaminants, including heavy metals.
