Nowadays, the importance of determining the numericalvaluation of environmental and genetic structure of populations of woody tree species in dealing with the introduction, without any doubt, is recognized by many researchers. The growing numbers of works associated with the introduction, examination of geographic cultures focused on the study of interspecific, inter- and intrapopulation, subpopulation genetic structure of quantitative and qualitative attributes which are important for forestry production and industrial wood processing. Heavy metals that were included in the scientific literature in the middle of the last century under such a negative name, at current stage already occupy the second place in the hazard level. In the future they might become the most hazardous or even more hazardous than APS and solid wastes. Contamination with heavy metals occurs due to their wide use in industry, causing them to fall into the environment bringing enormous damage. Human activity always brings to formation of numerous volumes of waste, including toxic. Industrial enterprises and large number of vehicles - obligatory accompaniments of urban environment are the major and permanent “suppliers” of toxic waste into the atmosphere. Under normal conditions, heavy metals are contained in soil in small quantities and are not hazardous. However, their concentration may increase due to vehicle exhaust, waste, residues and emissions during operation of industrial plants, during fertilize, etc.
