Combination of instrumental methods, and same time: geodetic measurements in the field with the monitoring data of the physical properties of land and computer processing of the data of studies have shown that the maximum concentration of heavy metals is formed at a distance from its source, Xm, that depends on the wind direction and speed. The results showed that the maximum concentration of heavy metals in the soil exceeds background levels of 1-3 orders of magnitude observed in the industrial and the adjacent area of a radius of 1-3 km. The scheme of pollution in the dominant directions of polluted substances have builded. Shown that the further from the source of contamination of heavy metals in the soil decreases and at a distance of 15-20 km, depending on the power source reaches the background level. Analysis of the X-distribution conducted by atomic absorption method on the device S115-M1 with sensitivity at about 0.0001 mg / kg. While establishing a monitoring network satellite data and Earth remote sensing (ERS) have precedence. According to the ERS can most quickly get the border areas, fairly accurate in their area, a digital image. It is shown to replenish and restore of information must be periodically fix in the database geodetic coordinates of individual land parcels or groups to be monitored.
