PHOTODESTRUCTION OF FOOD DYES FROM AQUEOUS SOLUTIONS UNDER THE INFLUENCE OF UV RADIATION

Olena YEVDOCHENKO — 2025-10-30

In accordance with the EU Directive "Directive (EU) 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption", drinking water is recognized as one of the important food products, for which standards for the content of various pollutants, including dyes, have been adopted. It should also be noted that one of the key goals for 2030 of the EU countries is to guarantee accessibility and long-term provision of water supply and sanitation for all (the sixth Sustainable Development Goal (SDG)).Modern industry produces more than 107 tons of various synthetic dyes, 15–20% of which end up in wastewater.Therefore, the problem of cleaning water bodies from dyes remains relevant.The paper presents a comparative analysis of the photodegradation of food dyes included in the red, green and yellow candies of the brands «Mintex+», «Bim Bom», «Duchess», «Citrus Mix» and «Juice Mix».It is shown that the degree of resistance of red dyes to ultraviolet radiation varies depending on the sample. The highest resistance was demonstrated by the dye used in «Citrus Mix» candies, while the lowest was demonstrated in the «Juice Mix» sample. It was determined that red dyes are generally characterized by relatively high resistance to photodegradation.A similar trend is observed for green dyes, although their resistance to UV radiation was lower. The dye used in the product «Duchess» was the most stable, and the least stable was in the «Bim Bom» candies. It was determined that green dyes are more vulnerable to photodegradation processes compared to red ones.The variability of the resistance of yellow dyes to UV radiation was determined. It was found that the dye from the «Bim Bom» lollipops demonstrated the highest resistance, the «Juice Mix» sample the lowest. According to the results obtained, the dyes can be placed in the following sequence in terms of the degree of resistance to photodegradation: red < yellow < green. The results obtained can be explained by the chemical nature of synthetic dyes and their ability to photodegradation processes.

RHEOLOGICAL PROPERTIES OF POLYVINYLACETAL COLLOIDAL SYSTEMS

Hanna TKACHUK — 2025-10-30

This study investigates the dynamic viscosity and thixotropic recovery of polyvinylacetal colloidal systems.Rotational viscometry was employed to determine the dependence of dynamic viscosity (η) on polymer concentration and shear stress (τ). The rheological properties of the polymers examined exhibited a common pattern: viscosity increases with concentration as a result of intensified intermolecular interactions.Detailed analysis of flow curves for polyvinyl butyral solutions revealed pseudoplastic behavior at low shear stresses.With increasing shear stress, a transition to Newtonian flow was observed, where the dynamic viscosity reached a minimum and stabilized. This effect is attributed to the breakdown of macromolecular structural conglomerates, which form in the resting state through hydrogen bonding with water molecules in the dispersion medium.A key finding is the demonstrated ability of polyvinylacetal gels to rapidly restore their structure through thixotropic recovery. The degree of thixotropic recovery (α), calculated as the ratio of effective viscosities during reverse and forward measurement runs, increased substantially with polymer concentration, reaching 94.58%. This property ensures that, following mechanical disruption during application, the polymer layer quickly regains its structural integrity and adhesive performance, which is of practical significance.The obtained results confirm the high efficiency of polyvinylacetals as adhesives and highlight the prospects for further research aimed at optimizing their compositions, exploring the influence of external factors, and elucidating adhesion mechanisms at the molecular level. Such efforts may lead to the development of novel, more advanced materials for the textile industry.

THEORETICAL AND METHODOLOGICAL PREREQUISITES FOR THE DEVELOPMENT OF UNIVERSAL COMPETENCIES (SOFT SKILLS) OF FUTURE SOCIONOMIC PROFESSIONALS IN THE CONTEXT OF DIGITAL TRANSFORMATION

Viktoria SAVITSKA — 2025-10-30

The focus on universal (transversal) competencies of future specialists in socionomic professions is determined by rapid changes in the professional sphere, production and economic relations, as well as global social transformations. The professional reality of the 21st century demonstrates the necessity for a universal form of certification for future socionomic professionals, serving as an indicator of the level of their universal competencies developed during higher education. For future socionomic specialists, attitudes toward a range of general professional skills have shifted significantly. These include the ability to flexibly and adequately respond to social reality, the capacity to construct a positive vision of the future, leadership qualities, teamwork skills, emotional self-regulation, creativity in solving professional and other tasks, and resilience. Among the essential cross-professional skills in the socionomic domain are conflict resolution abilities, effective communication, media literacy, critical thinking skills, and overall communicative culture as a vital personal trait of a professional.The issue of developing soft skills in future socionomic professionals is especially relevant in the context of digitalization, which requires a transformation of thinking to achieve educational goals and objectives. This paper emphasizes that universal competencies (soft skills) are a set of general abilities closely related to personal qualities. Unlike hard skills, which encompass theoretical knowledge and practical experience that can be taught, soft skills are innate, non-technical attributes that reflect an individual's approach to work. Their foundation lies in the personality of the future professional and the way they interact with others.

Ganna IAKYMENKO — 2025-10-30

Research Aim: to identify discrepancies between the competencies possessed by environmental science graduates and the needs of stakeholders. Based on the results of the GAP analysis, develop recommendations for improving the training system for students in environmental science specialties.Methodology. The study employed analytical methods (structuring, deduction, GAP analysis), as well as general and predictive methods.Scientific Novelty. The GAP analysis was conducted to identify gaps between the competencies of environmental science graduates and the requirements of the labor market. Discrepancies were revealed between employer needs and graduate competencies, with key issues identified as: untimely updating of educational components; lack of knowledge about environmental trends among both students and educators; insufficient mastery of international professional terminology; inadequate knowledge of environmental management; and a narrow range of competencies related to sustainable development and ESG (Environmental, Social, and Governance) that is insufficient for current demands.Eight recommendations were developed to improve the training system for higher education students in environmental science specialties across three directions: improving higher education management systems, developing educators’ competencies, and enhancing students’ competencies.Conclusions. Implementing the provided recommendations to improve the training system for higher education students in environmental specialties will increase graduates’ competitiveness in the labor market and reduce the adaptation period at their first job «in the profession». The use of informal education tools will help bridge the existing gap between student competencies and the current needs of businesses in the shortest possible time.

STUDY OF THE THERMAL TREATMENT METHOD FOR HIGHLY MINERALIZED WASTEWATER FROM INDUSTRIAL PRODUCTION

Karina BELOKON — 2025-10-30

Highly mineralized wastewater from industrial enterprises is one of the main pollutants of the natural environment.This type of liquid waste is contaminated with mineral substances such as salts of calcium, sodium, magnesium, etc.Despite the widespread implementation of recirculating water supply and new low-waste technologies, the volume of contaminated wastewater remains significant. Therefore, the purification of liquid waste from mineral contaminants is a major problem.A method for thermal neutralisation of highly mineralised liquid industrial waste using intermediate solid heat transfer has been proposed, offering promising prospects for application in metallurgy, chemistry, coal mining, energy and other industrial sectors. Laboratory equipment was developed, with an electric heater and an evaporation column containing an inert heat transfer medium in the form of metal balls. This work investigated the hydrodynamic regime of the evaporation apparatus during the disposal of highly mineralized wastewater on an intermediate solid heat carrier.Experiments were conducted on a granular packing with ball diameters of 10 and 15 mm. During the evaporation process, water was fed cyclically at a speed of 2, 2.5, and 3 m/s. As a result, it was found that the hydraulic resistance of the evaporation apparatus depends on the speed of the hot heat carrier and the type of packing (dry or wet).The conducted laboratory studies showed that the cyclical evaporation of highly mineralized wastewater using an intermediate solid heat carrier (metal balls) allows for reduced energy consumption and the effective removal of mineral contaminants from the water. However, the formation of a salt film on the packing elements reduces the porosity of the layer and increases hydraulic resistance. To ensure the efficient operation of the evaporation apparatus, it is necessary to maintain an optimal level of porosity.

ECOLOGICAL ASSESSMENT OF GROUNDWATER IN THE KRIVOOZERSKY DISTRICT OF THE MYKOLAIV REGION FOR THE IMPACT OF TOXICANTS

Nataliia HNATIUK — 2025-10-30

The article presents the results of a comprehensive study of groundwater from artesian well No. 104-E, located in Kryve Ozero, Kryvoozerskyi District, Mykolaiv Oblast. The research aimed to assess the water quality for domestic and drinking purposes and to determine the impact of toxicants on the aquifer within the fractured Precambrian granite. The article provides a detailed description of the well’s geographical location, technical characteristics, shaft and mouth design, as well as the geological section, which includes five main lithological layers: loams, sands, dense clay, fractured aquifer granite, and lower weakly fractured granites of negligible hydrogeological significance. The absolute elevation of the wellhead is 87.0 m, the static water level is 5.5 m, and the dynamic water level during pumping is 69.0 m, indicating a high potential of the aquifer and its suitability for domestic and drinking water supply.Detailed physicochemical, microbiological, and radiological studies of water from 2021–2023 were conducted, demonstrating consistently high water quality and compliance with all indicators of DSANPiN 2.2.4-171-10. No exceedances of the maximum permissible concentrations (MPC) of toxicants and harmful substances were detected.Nitrate, nitrite, ammonium, and radionuclide (^226Ra, ^222Rn, ^137Cs, ^90Sr) levels are within natural background or regulatory limits, indicating the absence of significant anthropogenic contamination of the aquifer. Microbiological indicators show no total coliforms, E. coli, or pathogenic enterobacteria, while the total microbial count does not exceed permissible limits, confirming the water’s safety for consumption.Special attention was given to operational aspects of the well, including optimal pump operation modes, preventive cleaning and flushing, and the establishment of a sanitary protection zone around the well. These measures ensure long- term stability of water quality and protect the aquifer from potential contamination.Promising directions for further research include regular groundwater monitoring to detect changes in composition, particularly the dynamics of toxicant accumulation, the influence of seasonal and climatic factors on water quality, and the use of biotesting to evaluate phytotoxicity and overall safety of water resources. Implementing these measures will confirm the safety of water for domestic and drinking purposes, optimize well operation regimes, and provide scientifically based recommendations for aquifer protection in Kryvoozerskyi District, Mykolaiv Oblast.

MECHANISMS OF STATE ENVIRONMENTAL INSPECTION FOR THE PROTECTION OF NATURAL LANDSCAPES AND ECOLOGICAL SAFETY

Vladislav PARAKHNENKO — 2025-10-30

The article examines modern mechanisms of state environmental inspection as an important tool for ensuring the protection of natural landscapes and maintaining environmental safety in Ukraine. It is emphasised that environmental threats caused by intensive economic activity, urbanisation, military actions and the effects of global climate change necessitate improvements to the system for monitoring compliance with environmental legislation. The essence of state environmental inspection as an institutional and legal mechanism that combines legal, administrative, organisational and environmental instruments of influence on economic entities and local self-government bodies is revealed.Attention is drawn to the role of the State Environmental Inspection of Ukraine in preventing violations in the field of environmental protection, timely detection of negative environmental processes, as well as in monitoring the state of land, water, forest and protected resources. The current problems of inspection effectiveness are analysed, including insufficient funding and technical support, staffing difficulties, fragmented legislation, and imperfect mechanisms for interaction with other state authorities. Separate emphasis is placed on the need to implement European standards of environmental control and monitoring, digitisation of inspection processes, and automation of environmental data collection.Particular attention is paid to the issue of preserving and restoring natural landscapes as a basic component of national environmental policy. It is determined that environmental inspection should perform not only a punitive function, but also a preventive and educational one, forming a conscious attitude towards environmental conservation in society and economic entities. It is shown that improving inspection activities will contribute to increasing the level of environmental safety, rational use of natural resources and the formation of an environmentally responsible model of public administration.Thus, state environmental inspection is seen as a comprehensive mechanism capable of ensuring the integration of the interests of the state, society and business in the field of environmental protection. Further development of this system involves strengthening the legal framework, introducing innovative approaches to environmental monitoring, and intensifying international cooperation to bring Ukraine closer to European environmental standards.

THE ROLE OF GRAIN DRYER MODERNIZATION IN THE DECARBONIZATION OF THE AGRICULTURAL DOMAIN

Olha KARAIM — 2025-10-30

Objective. The aim of this article is to analyze the techno-environmental aspects of grain drying complexes functioning in the agro-industrial sector in the context of carbon footprint formation and the ways to reduce atmospheric emissions as a component of the transition to a low-carbon economy.Methods. The study employs an interdisciplinary review approach based on the analysis of scientific publications from the Scopus and Web of Science databases, methodological guidelines, principles of life cycle assessment, and energy analysis. A comparative evaluation of conventional and alternative grain drying technologies was conducted, taking into account energy consumption, emission levels, and decarbonization potential.Results. Based on the results of the study, it has been confirmed that grain drying is one of the most energy-intensive stages of post-harvest processing of cereals, leading to significant consumption of fossil fuels and the associated formation of a carbon footprint, accompanied by substantial emissions of CO₂, CO, and particulate matter PM₁₀ and PM₂.₅. It has been established that the majority of conventional grain drying complexes lack efficient flue gas cleaning systems and are characterized by excessive energy consumption, which contradicts the objectives of decarbonization. The implementation of alternative energy solutions – such as biomass, heat pumps, and solar energy – as well as advanced filtration technologies and catalytic afterburning of exhaust gases, has been substantiated as a promising direction. The importance of life cycle assessment is emphasized as a tool for identifying "carbon-vulnerable" stages and developing strategies for transitioning to a low-carbon economy in the agricultural domain.Conclusions. Reducing the environmental impact of drying processes is crucial for the ecological modernization of agro-industrial production. The implementation of energy-efficient and low-carbon technologies – particularly through the modernization of drying equipment and the shift to renewable energy sources – is of strategic importance for the development of sustainable and climate-neutral agriculture.

ALKALI-ACTIVATED LONG-FLAME COAL. NANOPOROUS STRUCTURE AND ABILITY TO ADSORB HEAVY METALS

Volodymyr KUCHERENKO — 2025-10-30

Purpose. Study of the reorganizatіng supramolecular and porous structure of long-flame coal with increasing alkaline activation temperature, and assessment of its effect on adsorption activity towards lead cations.Methodology. Carbon materials (CMs) were obtained by heating KOH-impregnated coal to one of the temperatures within 350–825°C, isothermal holding for 1 h, cooling, washing from alkali and drying. The elemental composition was determined by a Carlo Erba 1106 analyzer. The content of acidic functional groups (AFG) was determined by Boehm titration. The spatial structure of CMs was studied by X-ray diffraction. The porosity characteristics of CMs were calculated using low-temperature (77 K) nitrogen adsorption–desorption isotherms (2D-NLDFT-HS method). Adsorption of Pb(II) cations was measured at 25°C and a constant CM content (1 g/l) in aqueous solutions. Adsorption kinetics were fitted using pseudo-first and pseudo-second order models. Adsorption isotherms were approximated by Langmuir and Freundlich models.Originality. The adsorption activity towards Pb(II) of carbon materials obtained by alkaline activation of long-flame coal at different temperatures at a small KOH/coal ratio (1 g/g) was studied for the first time. The adsorption equilibrium was found to be reached for 2 h, the adsorption kinetics obey the pseudo-second-order model, and the adsorption isotherms are better approximated by the Langmuir model. The adsorption rate is limited by the interaction of cations with surface adsorption centers, rather than diffusion into the porous system. The activation temperature was determined to be a key factor of forming CMs nanoporosity and ability to adsorb Pb(II) cations. With increasing temperature, the adsorption capacities of the cations monolayer, calculated from the Langmuir equation, increase from 0.143 mmol/g to 0.981 mmol/g.The basic processes of Pb(II) adsorption by CMs samples from long-flame coal is established to be ion-exchange reactions (exchange of AFGs protons for Pb(II)) and π-sorption (interaction of Pb(II) with the π-system of coal polyarenes). The contribution of π-sorption was shown to increase with the activation temperature and is dominant (87–91%) in materials obtained at 800–825°C. The sufficiently high capacity for Pb(II) of these CMs allows us to predict their effectiveness in purifying water from other heavy metals.

WATER QUALITY IN THE IRPIN RIVER IN THE POST-MILITARY PERIOD

Maryna LADYKA — 2025-10-30

Military operations lead to significant changes in the functioning of aquatic ecosystems. Both direct and indirect consequences are manifest in the ecological, social, and economic spheres. Assessment of the current state of water resources in areas where hostilities have continued is necessary to study the scale and specifics of their pollution and predict long-term consequences.The goal of our study was to analyse changes in the water quality of the Irpin River in the post-military period. A comparative characteristic of water samples taken in 2024 with the average annual data of state monitoring of the quality of surface waters of the Irpin River (hydrochemical station in the village of Gostomel) for the period 2020–2023 was carried out. The observation points were chosen within the Kyiv region (Irpin, Demydiv village, Kozarovychi village), taking into account the spatial difference in the impact of military actions and the intensity of anthropogenic load on the river ecosystem.On the basis of a comparative analysis of the values of ecological indices (IE) of the water quality of the Irpin River in the pre-war and post-war periods, deterioration of its quality was established. In particular, in the pre-war period (2020–2021) according to the worst values (EI = 3.98) it belonged to class III, quality category 4 (“satisfactory”, “slightly polluted” waters), and in the post-war period (2022-2023) (EI = 4.83) – to class III, quality category 5 (“mediocre”, “moderately polluted” with a tendency to “satisfactory”, “slightly polluted”) in accordance with the data of the state monitoring point of surface waters on the Irpin River (Gostomel village).The decline in water quality was primarily reflected in the increase in the level of organic pollution and the deterioration of trophic and saprobiological characteristics. The main sources of organic matter (mainly nitrogen and phosphorus compounds) are untreated municipal wastewater (Irpin city, Gostomel village), as well as runoff from agricultural lands and private households (Demydiv village, Kozarovychi village). This, in combination with the summer increase in water temperature, leads to a deficit of dissolved oxygen (≤ 4 mgO2/dm3) and a violation of the natural ecological balance in the river.The limniophilous (lake) conditions with slowed water exchange have formed in the flooded areas of the valley. This causes a deterioration in the oxygen regime and contributes to the accumulation of organic compounds in the water. The degree of anthropogenic load on the surrounding areas determines the dynamics of self-purification processes and the speed of recovery of the hydroecosystem.

POST-PROJECT MONITORING AS A BASIS FOR ENVIRONMENTAL ASSESSMENT FOR BIODIVERSITY CONSERVATION IN FOREST ECOSYSTEMS

Viktoriia MELNYK-SHAMRAI — 2025-10-30

The article examines the role of post-project monitoring as a key tool for environmental impact assessment in the context of biodiversity conservation in forest ecosystems. It outlines the legal and organizational frameworks for implementing environmental impact assessment mechanisms in Ukraine, which were developed to adapt national legislation to the requirements of the European Union and international environmental agreements. The study also discusses the specifics of their application in the forestry sector. The article presents an analysis of post-project monitoring data from forest ecosystems, which demonstrates the complex nature of impacts on environmental components, including atmospheric air, water resources, soils, flora, and fauna. It was found that biodiversity is the most vulnerable element, as the disruption of natural trophic links, a decrease in the number of rare and endangered species, habitat degradation, and fragmentation lead to a decline in the ecological stability of forests. A SWOT analysis was conducted using the example of the "Slovechansky Forest Enterprise of the Agro-Industrial Complex" to identify the strengths, weaknesses, opportunities, and threats of forestry activities, while considering the need for biodiversity conservation. Special attention is paid to integrating the results of post-project monitoring into the environmental management system, which helps in making science-based decisions for ecosystem preservation.The practical value of this work lies in providing recommendations for government bodies, forestry enterprises, and environmental protection organizations on how to improve the post-project monitoring system, optimize forest use, expand protected areas, and enhance cooperation with local communities. Future research prospects suggest the need to implement geoinformation technologies and remote monitoring to analyze the spatial dynamics of biodiversity. In conclusion, post- project monitoring is defined as a key mechanism for the environmental support of forestry activities, ensuring not only control but also adaptive management of natural resources in accordance with EU environmental requirements.

ECOLOGICAL ASPECTS OF THE STATE OF THE FOREST FUND OF THE KIVERTSIV FOREST DISTRICT

Bogdan FEN — 2025-10-30

The current state of environmental security in Ukraine and the world requires a rethinking of approaches to the use of natural resources, in particular, forest resources. Forests play an extremely important role in stabilizing the climate, preserving biodiversity, water protection, recreation, and in supporting sustainable economic development. In the context of global warming, increasing anthropogenic pressure on the environment, and increasing the frequency of natural disasters, the problem of effective management of forest resources, preservation and restoration of forest ecosystems is of particular importance.The relevance of the research topic is due to a number of contradictions: on the one hand, the economic benefits from forest use stimulate intensive timber exploitation, on the other hand, the environmental consequences of excessive logging cause forest degradation, soil erosion, reduction of moisture reserves, etc. Despite the development of many regulatory documents, the issues of ecological balance of forest use remain insufficiently studied in the applied context of individual enterprises. Local analysis of the forest fund taking into account the dynamics of felling, reforestation and zoning by functional purpose is not sufficiently covered in the scientific literature. The work conducted a study of the structure and ecological parameters of forest resources of the Kivertsi Forestry Department of the Polissya Forest Office branch of the State Specialized Economic Enterprise "Forests of Ukraine", and an analysis of forestry management in the studied region was carried out.Structured data on the dynamics of the forest fund by categories of forest plots, division of areas and stocks of stands of the dominant species of Scots pine and Scots oak by age classes.

TOXICOLOGICAL RISKS OF FOREST RESTORATION ON TERRITORIES WITH AMMUNITION CONTAMINATION

Illia TSYHANENKO-DZIUBENKO — 2025-10-30

This review study of toxicological risks of forest restoration on territories with ammunition contamination systematizes current scientific knowledge about complex interactions between military contaminants and forest ecosystems in the context of the Russian-Ukrainian war and international experience. Over 160 publications on explosive compound toxicology, heavy metal accumulation, and ecological barriers to forest recovery after military actions were analyzed. Phytotoxic effects of major explosive compounds were systematized: trinitrotoluene (TNT) demonstrates highest phytotoxicity with LC50 for Scots pine seedlings of 45 mg/l and causes plant tissue degradation of 26.8%, while hexogen (RDX) and octogen (HMX) are characterized by viability reduction of 20.4% and 18.4% respectively with higher persistence in soil environment. Data on heavy metal accumulation from military activities were generalized, showing critical lead concentrations up to 1067 mg/kg in soils and 1495 μg/l in groundwater, which is 53 times higher than background values and creates long-term geochemical barriers for forest regeneration over decades. Specific ecological obstacles to forest recovery after the Russian-Ukrainian war were examined, including 38,589 hectares of damaged forest cover in three regions during 2022, contamination with unexploded ordnance, cascade disruptions of nitrogen and phosphorus biogeochemical cycles, degradation of mycorrhizal symbioses, and structural vulnerability of monoculture plantations.International bioremediation experience was systematized, including field trials of genetically modified switchgrass for hexogen degradation (remediation rate 27 kg/ha over three years) and post-conflict studies in Colombia after the 2016 FARC peace agreement, which revealed paradoxical increase in deforestation rate by 177% after cessation of military actions. A conceptual classification of military contaminants by phytotoxicity and persistence, matrix model for risk assessment for different types of forest biogeocenoses, and hierarchical scheme of ecological barriers to forest succession were developed. A comprehensive algorithm for assessing biosafety of forest restoration measures based on risk analysis criteria was presented, including six sequential stages from contaminant identification to technical recommendations formation for remediation measures. Review results demonstrate critical necessity of integrating toxicological analysis with modern remediation technologies and developing interdisciplinary approaches in military ecology for effective restoration of militarily disturbed forest landscapes in the post-war period.

ASSESSMENT OF THE AIR BASIN STATE OF THE WESTERN UKRAINE REGIONS IN CONDITIONS OF SUSTAINABLE DEVELOPMENT

Angelina CHUGAI — 2025-10-30

Assessing the technogenic load on the air basin is an important task that has become even more urgent since the outbreak of full-scale military operations in Ukraine. As a result, over the last 3 years, a significant amount of pollutants has been emitted into the air and significant environmental damage has been caused. The territory of Western Ukraine, compared to other regions of Ukraine, is not characterized by high indicators of technogenic impact on the air basin. Most scientific publications are focused on assessing the transport load on the atmospheric air in the western regions. The aim of the study is to assess the state of the air basin using the parameters of sustainable development. For the assessment, the parameters for calculating the environmental dimension index of the metric for measuring sustainable development processes were used. The calculations were made for two categories of environmental policy – Environmental Systems and Environmental Load. It was determined that the territory of Western Ukraine in 2019–2023 was characterized by moderate indicators of the air basin load. In the category “Environmental Systems”, the worst performance in terms of sustainable development is recorded for sulfur dioxide. Ternopil and Khmelnytsky regions are the most pressured regions in pollution levels. The worst situation in the category “Environmental Load” was registered in Lviv, Rivne and Ternopil regions. The best indicators were registered in Volyn and Chernivtsi regions. It has been suggested that Ivano-Frankivsk region may be among the regions with the worst conditions. In terms of transport emissions and emission density, the worst indicators were registered in Rivne, Ternopil, and Lviv regions, and the best in Chernivtsi. In terms of emissions of certain pollutants, the worst conditions were registered in Lviv region, and the best in Zakarpattia region. The parameters of the “Environmental Systems” category are characterized by the worst indicators in terms of sustainable development.
