Hydrochemical analysis of the dynamics of changes in the quality of surface waters of the Oskil River.</p> <p>Methods. Comparison of hydrochemical indicators with norms of maximum permissible concentrations (MPC). To determine the water quality criterion, the MPC for fisheries reservoirs was taken. The general assessment of water quality is determined by the following methods: water pollution index (WPI), modified WPI and specific combinatorial water pollution index (WPI).</p> <p>Results Based on the water pollution index, it was determined that the river corresponds to the category "very clean" to "moderately polluted". The water pollution index of the Oskil River indicates that the upper course corresponds to the II class "clean", but near the city of Kupyansk the water quality deteriorates to the III class "moderately polluted", and further downstream it again becomes the II class "clean".. According to the methodology specific combinatory water pollution index, the river water is rated from "very clean" to "moderately polluted". The pH in the water varied from 6.08 to 9.27. The total water hardness varied between 10.0 and 2.8 mmol/dm3. The oxygen level indicates an acceptable water condition in most areas. Compounds, the concentration of which most often exceeds the MPC for all observation posts, are: chromium 6+, manganese, copper, petroleum products. Other compounds may also exceed the MAC in some posts and observation years, including total iron, sulfates, zinc 2+ , nitrites, cobalt, phenols, and BSC5.</p> <p>Conclusions. Significant variations in the concentrations of chemical elements in different areas were found in the water quality of the Oskil River. Index of water pollution of the Oskil River according to the calculations of the IZV mod. shows that in most cases for all years of observation, the river corresponds to the III class "moderately polluted". The change in the KIZ indicator along the Oskil River shows that the level of pollution of the river is low along its entire length and it mostly remains under the influence of insignificant anthropogenic influence.</p> O.

The results of the chemical analysis of soils were carried out by the ICP-OES method on the iCAP6500DUO device.</p> <p><strong>Results</strong>. Monitoring researches were carried out by route advance by car, first from the village of Sychivka (on the border with the Vinnytsia region) to the east to the city of Cherkasy and in the opposite direction to the city of Uman. A total of 8 stops were made for the relevant measurements and sampling. The intensity of the noise load increased around large settlements (Uman, Smila, Cherkasy), and on intermediate sections of the highway, where vehicles could develop high speeds. The dependence of dustiness on the total carrying capacity of vehicles was determined. The radiation background for all polygons corresponded to the background values. Chemical analysis of soil samples directly near the track and at a distance of 25-30 m from it determined a close dependence on the distance. A generalization of various parameters of the current state of roadside ecosystems is made. In particular, the recording of various types of ruderal plants made it possible to draw a diagram of the degree of completion of the formation of roadside ecosystems.</p> <p><strong>Conclusions.</strong>&nbsp;After the construction of the road surface, over a certain period of time, plant and animal communities are formed along it, which later show signs of ecosystem dynamics</p> S.

On the basis of the previously conducted geoecological assessment of the forest landscapes of the model area by the means of landscape and ecological planning, the indicator of the amount of ecosystem services to provide for medieval stands by species composition per 1 ha was determined. Thus, on the basis of the Analytical Portal of the state wood accounting system, it was determined that for 2022, the average value of wood by species composition for the Kharkiv region was determined. Thus, the value of the ecosystem service for providing wood is about 604.5 million hryvnias. In terms of unit area (1 ha), the indicator of the ecosystem service will be UAH 13,247/ha. The indicator of the value of ecosystem services for regulation, in particular of the carbon capacity for the model plot, was determined for medieval stands by species composition per 1 ha.</p> <p><strong>Conclusions.</strong> The proposed use of geoecological assessment based on the landscape-ecological approach provides an opportunity to take into account landscape conditions, the impact of anthropogenic activity, as well as the results of management decisions in nature management.</p> N.

It is substantiated that with moderate and weak winds, the intensity and energy of forest fires in Ukraine usually do not exceed 4-5 magnitudes, i.e., a moderate or high level. Fires of this level occurred, for example, in the spring, summer, and fall of 2020 in a number of regions of Ukraine.</p> <p><strong>Conclusions.</strong> The developed special scales for classifying forest fires according to various parameters are an effective tool for qualitative and quantitative characterization of the intensity of forest fires and their environmental consequences. The obtained results can also be used to assess environmental impacts, material damage and social losses.</p> L. F. Chernogor, A. N. Nekos, G. V. Titenko , L. L.

Based on the use of general scientific and special methods of cognition. The hypothetical and deductive method was used to reveal the content and essence of the concept of "crisis monitoring". The method of structural and functional analysis is used to identify current trends in the preparation, planning and implementation of measures related to the improvement of crisis monitoring. The method of generalisation and comparison is used to assess the current state of the crisis monitoring system, to evaluate its actual and forecasted state; deterioration of people's living conditions.</p> <p><strong>Results</strong>. The article shows that emergency and crisis situations are an integral part of the social system. The author analyses the scientific heritage and legislation, which makes it possible to conclude that a crisis situation, critical situation, crisis, emergency situation are the defining properties of these systems and are the result of the action of factors. The author establishes that emergency and crisis situations develop in time and space and allow identifying certain stages at which crisis situations may arise.</p> <p><strong>Conclusions</strong>. The consequences of emergency and crisis situations are always negative, but there is a direct and inverse relationship between crisis and emergency situations.</p> L. I. Demchuk, I. G.

With an increase in the concentration of model solutions, there is a gradual inhibition of the growth of sprouts and especially the roots of the test objects. The most toxic effect on the test object, according to the research results, was caused by Cd - a phytotoxic effect from weak to strong was observed under the influence of different concentrations of model solutions. Experimental determination of the phytotoxic properties of model solutions of heavy metals Cd, Pb, Ni, Cu on test plants <em>Raphanus sativus</em> L. showed that the imbalance of growth processes is absent only when using solutions with concentrations of 1 MPC and 5 MPC Cu, i.e. practically without exceeding the regulatory requirements for soil quality. Model solutions of Cd and Cu 40 MPC had the highest degree of imbalance in the growth processes of the test plants <em>Raphanus sativus</em> L. – strong for the experimental study we conducted.</p> <p><strong>Conclusions.</strong> Biodiagnostics using <em>Raphanus sativus</em> L. test plants revealed signs of toxic effects where<em> Avena sativa</em> L. test plants did not experience inhibition, or the determined phytotoxic properties of the model solutions were lower, which is determined by the imbalance of growth processes. The above-mentioned discrepancies between the results of biodiagnostics of model solutions with the help of different test cultures make it possible to assert that it is necessary to introduce a comprehensive indicator for determining the phytotoxic properties of the studied samples, with the help of which it is possible to level such discrepancies.</p> O.
