In today's urbanization are intense man-made land cover urban ecosystems. Modern urban ecosystems, is antropgenno transformed environment (created for favorable living person) with high dynamics of technological processes (including spatial movement and accumulation of toxic substances in urbopochve). One of the components of technological change in the urban environment is the contamination of soils in urban areas with heavy metals, which are biochemically active man-made substances. They are characterized by high toxicity and ability to accumulate in living organisms (and thus heavy metals are a source of danger to the body of the urban population as a result of constant contact with them), breaking its healthy functioning. Thus, the process of pollution pochvogruntovoy strata urban area with heavy metals is one of the most important and pressing issues urboekologii. Scale process of anthropogenic impact on the soil and the soil in urban areas, respectively, has a significant number of human sources, which include power generation facilities, landfills, with domestic and industrial waste, municipal utility and transportation system. Development of construction activity and work on the improvement of urban areas also leads to a process of heavy metal contamination of soils. Due to the fact that the city of Astrakhan is a large dynamically developing urboecosystems, within which technogenic processes occur with high intensity and affect all parts of nature, particularly on the ground, was used to study the concentration of heavy metals in the surface layer gorodskogopochvennogo cover. The article describes the soil contamination by heavy metals and the spread of the pollution in the city of Astrakhan.
