Abstract

Environmental degradation of urbanized areas negatively affects the population health. Air pollution is a priority among other environmental factors affecting incidence. The issue of environmental pollution by heavy metals, which exhibit high toxicity in trace amounts and have a high migratory ability and a tendency to bioaccumulation, has become increasingly urgent in recent years. The creation of sanitary-protective sectors of woody plant species should contribute to the deposition of aero-pollutants, as well as the absorption of toxicants from the soil. However, the performance of the function of a phytofilter for a long time negatively affects the vitality of trees themselves. A study of the absorptive capacity of individual species of woody plants and their reaction to the toxicants will make it possible to predict the stability of protective forest stands and justify forestry activities. This work presents the results of many years of research on the assessment of the relative living state and characteristics of the accumulation of heavy metals (Cu, Cd and Pb) with balsam poplar (Populus balsamifera L.) under conditions of industrial center of Sterlitamak. The metal content in the samples was determined by atomic absorption spectrometry. The biological absorption coefficient and the conversion coefficient were calculated. It was revealed that under the conditions of polymetallic pollution of the Sterlitamak’s industrial center, the relative living condition of the balsam poplar stands is assessed as “weakened”. The high content of metals in the soil’s root layer negatively affects the vitality of trees. Despite this, poplar stands make a significant contribution to limiting the spread of pollutants in the environment. The highest content of heavy metals in healthy trees is noted in the root system, thereby contributing to the preservation of favorable concentrations of chemical elements in the aboveground organs. With an increase in the concentration of copper, cadmium and lead in the roots of weakened trees, their increased amount is also observed in the aboveground organs (branches and leaves).
