The tasks of the research was to identify patterns of changes in the chemical composition of the soil, plants, water, depending on the level of technological and urban impact. 239 Surveyed territory and surroundings of cities and other human settlements in the urban and industrial pollution, as well as agricultural areas, where studies the effects of long and short-term deposits of chemical fertilizers and soil reclamation. The investigated area stable number of data elements that were found on the content of total forms of heavy metals. No sharp limit exceeded permissible concentration (MPC) mobile forms the following heavy metals: lead, cadmium and copper. Content of trace elements and heavy metals in the soil samples and the island Territories do not exceed established norms (MPC). The acidity of the soil medium is in the ranges up to average acidity slightly. The study found that soil samples taken in the Ussurijsky nature reserve and the island Territories, can be considered clean and used for comparison in examining ecosystems affected by anthropogenic pollution. Thus, it is established that the overall level of pollution in the environment of industrial and urban areas of heavy metals can be characterized as stable, not to exceed the norm. For mobile forms of defined chemical elements are isolated cases of exceeding the maximum allowable concentration. The overall level of contamination of the environment with heavy metals can be described as stable. No sharp limit exceeded permissible concentration (MPC) mobile forms the following heavy metals: lead, cadmium and copper. Protected and insular territories can be used as benchmarks when examining the damaged and contaminated ecosystems. The estimation of environmental state by chemical, microbiological and hydrobiological (macrozoobenthos) methods is corresponding with each other in general.
