Annotation The paper presents an assessment of technogenic contamination by heavy metals of soils and woody plant species in the city of Chita, settlement of Pervomaysk and settlement of Novoorlovsk, where there are mining enterprises. The study shows coefficients of technogenic concentration of elements, biological absorption, total rate of soil contamination and biogeochemical activity of species. The ratio of soil contamination decreases in the following way: Pervomaysk (Zabaikalsky Ore Mining and Processing Enterprise) > Novoorlovsk (Novoolovsky Ore Mining and Processing Enterprise) > Chita. The soils in Pervomaysk and Novoorlovsk settlements are contaminated with Ni, Zn, Sr, Rb, Ti, Cu and Cr. In Chita they are contaminated with Zn, Ni, Sr, Rb, Ti. In terms of Zc, soils are classified as acceptable, with the possible use of the plants (Zc <16). Accumulation of heavy metals in woody plants can be described as a barrier type, depending on the biological characteristics of species and their concentration in the soil. The study describes the species that concentrates zink (Populus balsamifera) and shows the role of woody plants in the process of purifying the environment from pollution by heavy plants.
Key words environmental pollution, heavy metals, intensity of elements absorption, soil, woody plants.
