The heavy metals circulating in the biosphere have a huge negative impact on ecosystem components. At the same time however, the real danger from the environmental pollution by the heavy metals (HM) is constituted not by gross volume of metals, but by their mobile forms as the last practically define the accumulation of elements in biomass and influence the biological activity of soils. Meanwhile, the level study of this question is very weak. The influence of soil consolidation on HM mobility is almost not unknown. In this regard at wood sites with unequal anthropogenic loading we have conducted researches which have demonstrated the dependence of toxic heavy metals forms, diverse by durability of communication, on the consolidation of soil. In many respects the density of soil profile defines the formation of the soil modes - water-air, temperature, oxidation-reduction, biochemical, and often makes decisive impact on demonstration of the soil main ecological functions, conditions of growth, development and efficiency of plants, microorganisms activity and soil fauna.
