“…points out to such an important disadvantage of using plastic in road building as release of hazardous substances in high temperature (Belotserkovskaya, 2020). In high temperature and when burned, polyvinyl chloride (PVC) emits dangerous carcinogenous dioxins, and also lead and cadmium -the most hazardous heavy metals -into the air (Buts, 2019, Buts, 2020. Even when heated insignificantly, PVC generates vinyl chloride, dioxins and other toxic compounds present in the additives (stabilizers, oils, plastifiers, fillers) used for PVC production.…”

Currently, society and industry are developing at a rapid pace, and an increas- ingly serious problem of the modern world is environmental pollution, requiring recycling and reuse wastes. Modern technologies in the field of road construction involve the use of polymeric materials obtained from waste recycling. Almost nothing is known about soil contamination by plastic in general and the destruction of roads in particular; probably because of lack of awareness and absence of standard methods for quantifying plastic components in soil. The contemporary data suggest that flow of plastic has already reached a value similar to that found for other contaminants, such as heavy metals. In particular, migration is observed for plastic microparticles, but so far, their effect on groundwater has not been studied. Therefore, additional research is urgently needed to shed more light on the fate and impact of these persistent materials in the terrestrial environment. The purpose of the study was a geoecological analysis of the risks of using polymer waste in construction of roads to the geological environment. To ensure environmental safety in the implementation of technologies for the utilization of polymer waste, it is necessary to take into account their chemical composition, the ability to form hazardous products in increasing temperature, hazard class, physical and chemical properties. We propose criteria for assessing the possibility of recycling polymer waste in road construction, namely for the manufacture of asphalt concrete. According to the pro- posed overall criterion, taking into account not only technical and economic indicators, but also the environmental component, we can recommend the use of HDPE and LDPE, as well as PP for use in road construction. Taking into account the total criterion, we recom- mend using HDPE, LDPE as the most acceptable waste for road construction,, as well as PP. The technological scheme should include the collection, sorting of these plastics, as those that do not contain hazardous chemicals. Temperature conditions for manufacturing asphalt involve heating and converting the components into the liquid phase for uniform mixing of the entire composite. Under those temperature conditions, chemical compounds that are harmful to the environment and humans would not be created. The possibility to substitute part of the bitumen, to obtain asphalt concrete with high performance, increased service life shows the cost-effectiveness of using these groups of polymer waste in the technology of manufacturing asphalt concrete. The lack of regulatory framework and technical standards for working with polymers for paving brings the problem of plastic roads to the legislative level.

It has been analysed that wildfires are the most influential factor in environmental pollution. The ecological consequences of wildfires consist primarily of atmospheric air pollution with carbon monoxide, products of combustion of combustible materials, and the burning of oxygen. Plant combustion also contributes significantly to planetary environmental changes: climate warming, ozone depletion, acid rain, chemical and radioactive pollution of the atmosphere, water, and soil. With wildfires, soot particles, that is, carbon and products of incomplete combustion of wood, enter the air. Smoke, which is formed during fires, explosions, ignitions, etc., during the combustion of plant biomass (grasses, leaves from trees and shrubs, mosses, lichens, peatlands, forest litter and needles), is an aerosol-gas mixture containing hazardous substances dangerous to the environment and humans. Biomass burning is a global source of gas and dust pollution of the atmosphere and is considered one of the determining factors of ecotoxicological risks for public health. The negative impact of fires from military actions on the human body is acute and delayed. Acute exposure leads to hypoxia due to carbon oxides, increased consumption of oxygen from the air during combustion, irritation of the respiratory tract, and difficulty breathing. Delayed exposure is due to toxic, mutagenic, and carcinogenic effects. The toxic impact of fires on the life and health of the population is not only a threat to life but also an adverse effect on human organisms of heavy compounds of chemical substances represented by the combustion products of plant biomass of forests, peatlands, vast agricultural lands, including crop rotations and pastures. Often, this impact occurs in combination with typical atmospheric air pollution: emissions from industrial enterprises and motor vehicles. The peculiarity of such a combination is the complex synergistic effects of chemical compounds and high air temperature with significant relative duration (decades, months) of emergency environmental situations. Keywords: toxic factors, fires, ecosystem, human activity.

“…Drawing on the conducted assessments, the studies (Buts, Asotskyi, Kraynyuk, Ponomarenko, Kovalev, 2019) developed mathematical models for the influence of heavy metals on the development of composite indicators of the condition of water bodies, determining the conditions of migration and concentration of compounds of heavy metals, and composing an equation for calculating concentration of mobile forms of heavy metal compounds.…”

The lack of effective mechanisms of the methods of basin management, control of and responsibility for the ecological state of surface sources of drinking water leads to the fact that the main man-made objects that determine the ecological state of surface water sources are most often located in one oblast, while the production and consumption of the drinking water from those sources occur in the territory of other oblasts, which complicates the effective management of environmental safety of surface water sources. This is especially true for the regions of Ukraine which are poor in surface water resources, located in the basin of the Siversky Donets River, the water bodies of which are the main sources of water supply in the eastern regions of the country. The main consumer of water is Donetsk Oblast (over 50 % of the annual volume), and Kharkiv and Luhansk Oblasts together consume approximately the same volume of water per year (up to 50 % of the annual volume). Therefore, it is important to substantiate the integrated indicators of the ecological status of the water body to improve the environmental safety of surface water sources. The paper shows that oxygen indicators play an important role in the ecology of a water body. They are associated with the assimilative ability of water, the ability of water to decompose organic matter. Therefore, the content of dissolved oxygen and biochemical oxygen consumption in water is of great interest not only in terms of life development, but also as a composite measure of the ecological status of the aquatic environment. The relationship between the value of the combined index of water pollution and the value of biochemical oxygen consumption makes the indicator of biochemical oxygen consumption important for the integrated assessment of water contamination with various organic substances. For the tasks for which we justify the choice of composite measures of the ecological condition of surface waters, it is more important to identify the effects of contamination not directly at the site of contamination, but at some distance from it and after some time. Therefore, the use of the amount of dissolved oxygen and biochemical oxygen consumption as indicators that characterize the oxidation of pollutants present in water is the most appropriate for the tasks of timely monitoring of water bodies. Therefore, as a composite indicator for characterizing the condition of the watercourse and conducting timely monitoring, we chose oxygen indicators.
