The data on the state of radioactive contamination of leaves of plants growing directly on the territory of the drained part of the cooling pond of the Chernobyl NPP are presented. It was shown that the main source of contamination is the root intake of radionuclides (137Cs and 90Sr). This contamination is larger in previously drained areas compared to recently exposed ones. Hot particles were found on the leaf surface by autoradiography. Their total β-activity is a few percent of the total pollution. Possible sources of hot particles – resuspension in the air in the region of the northern part of the cooling pond are discussed.

The City

Studies conducted in different cities have shown that trees growing in urbanized areas reduce noise levels and cleanse the air of solid particles, ozone, sulfur dioxide, carbon monoxide, nitric oxide and other pollutants contained in car fumes, transport dust and generated by industry. The reaction to the influence of negative factors in woody plants is in disturbances in metabolism and biochemical composition, their general development also changes, and their population decreases. The indicators of disorders occurring at the cellular and tissue levels are more sensitive to the influence of negative anthropogenic factors in comparison with external manifestations. The research was carried out on woody plants: small-leaved linden (L. Tíliacordáta), horse chestnut (L. Aésculus); the soil. The research was carried out in 9 districts of Volgograd. The assessment of the state of woody plants was carried out by the visual method based on external signs. GOST methods were used to determine the concentrations of chemical elements in the foliage and soil of woody plants. Using physical and chemical methods, the concentrations of chemical elements in the soil and biomass of woody plants taken from the selected areas of the city of Volgograd were obtained, and the correlation between these indicators and the life state of woody plants was determined. The dependence of the indicators of the concentration of nutrients in the soil and the state and viability of woody plants was well traced. In general, the state of most of the woody plants of the city was healthy or moderately weakened. Such a high level of the life state is explained by the relatively young age structure of the studied plants, because at a young age woody plants are more resistant to negative factors of the urban environment. The revealed features of the life of woody plants in the city can be taken into account in the practice of city green building.

State Of Affairs

The state of woody plants determines the viability of forests and environmental safety in urban environments largely. Therefore, scientific studies of the tree response as a complex biosystem on environmental factors changes are especially relevant due to the growing threat of environmental disasters (environmental pollution, active felling, etc.). Many modern methods for assessing the state of such complex macromolecular systems are verbal in nature due to the lack of non-destructive testing methods with controlled accuracy. The shortage of experimental measurements retards the development of modeling the state of trees and, consequently, the development of methods for predicting their response on the influence of external factors. The development of digital technology can change the current state of affairs in this sphere. In the report, within the framework of a systematic approach, the possibility of using digital technologies at analyzing the response of the state of woody plants on environmental factors changes has analyzed. The results of studying the flow of salt solutions in the xylem of tree trunks are presented to solve the problem. Based on experimental data, models are proposed that can become the basis of calculation systems for analyzing the state parameters of woody plants and predicting the occurrence of environmental disasters.

It has been experimentally found that the mono groups of Juniperus virginiana L. have less resistance to the natural and climatic factors, this is firstly due to increase in the height of biomass of the tree and secondly to application of loads in the form of a wind force, as well as an additional mass in precipitation. According to the results of diagnostics of the state and monitoring of sustainability of Juniperus virginiana L.plantings, the accident risk is estimated at 14% of the total number (585 units).
