Abstract

Phytoindication can be carried out by the response of plants in the species most sensitive to pollutants, or by the accumulation of harmful substances in the body of plants. Therefore, among plants, bioindicators with a high sensitivity to pollutants and storage bioindicators are distinguished. The dendrochronological method makes it possible to study changes in climatic conditions on the planet and the effect of various ecological and anthropogenic factors on woody plants of the ecosystem. A reliable correlation has been established between the levels of air pollution by pollutants and a decrease in radial annual growth in tree species. The article discusses the assessment of environmental pollution using phytoindication. One of the signs of phytoindication in the industrial zone is the annual growth of wood of these trees. According to the data obtained, under the influence of industrial waste, first of all, there is a decrease in the annual growth of wood of existing trees.
