The study investigates the patterns and ecological consequences of vegetation succession in areas affected by ground fires within the Roztochya region of Ukraine. The objective was to identify key stages and drivers of post-pyrogenic vegetation recovery and assess the role of dominant species in...

Phytomeliorative efficiency of vegetation species composition on devastated landscapes, including landfills, is a key factor in improving the ecological state at both local and regional levels. This article presents results of assessing heavy metal content and phytomelioration potential of...

The paper analyzes the ecological state of landfills located within recreational zones, using the example of the Bronytsky landfill (Lviv region).The study was carried out using an integrated approach: physicochemical parameters were combined with chemical analyses, bioindication methods and spatial mapping.It was found that the temperature of the waste mass during the study fluctuated within +25…+32 °C, which contributed to the intensive migration of pollutants.In soil samples from the zone of direct impact, the Pb concentration reached 42.5 mg/kg, Cd — 1.2 mg/kg, which exceeds the background values ​​by 3–4 times.The Zn content in soil samples was 180 mg/kg versus 60 mg/kg in the control zone.Bioindicative studies revealed a 28% decrease in vegetation species diversity, and the number of heterotrophic bacteria decreased 2.1 times compared to control areas.According to the results of GIS analysis, local “hot spots” of pollution are traced in the southern sector of the landfill at a distance of up to 350 m from the boundary.The practical significance of the study lies in the formulation of recommendations for the creation of a buffer zone with a radius of at least 300 m, the implementation of reclamation measures using phytosanitary crops and the introduction of systematic monitoring at least twice a year.

Introduction. Military actions negatively affect the environment, in particular surface waters. Pollution is caused both by the ingress of equipment, weapons, explosives and explosion products into the water, and the ingress of various pollutants as a result of the destruction of facilities, treatment facilities, etc., as well as changes in production processes.Purpose. The purpose of the research is to compare the quality of surface waters in rivers located near the places of hostilities and in the rear areas of Ukraine according to monitoring data.Methods. The work uses statistical, comparative and analytical research methods.Results. The study was conducted based on water monitoring data for the Dnieper (Zaporizhzha) and Western Bug (Sokal) rivers. Analysis of the results of water monitoring by key quality indicators enables the identifying the influence between water quality indicators and the monitoring period - before the war and after its outbreak. Monthly monitoring data from 01.2021 to 10.2024 of the concentration of ammonium ions, BOD5, dissolved oxygen, nitrate ions, nitrite ions, sulfate ions, phosphate ions and chloride ions were analyzed.Dependency graphs were constructed, the main statistical characteristics were calculated. The indicators were compared with the maximum permissible concentrations established by regulatory documents.The presence, type and closeness of relationships were determined by the correlation coefficients between the corresponding quality indicators of both rivers for the entire research period, the period before the war and after its beginning. Correlation matrices were constructed between the water quality indicators of each river during these periods. Differences in the behavior of the indicators, their statistical characteristics, as well as correlation relationships were identified.Conclusion. According to the results of monitoring the quality of surface waters of the Dnieper River (Zaporozhye city) and the Western Bug (Sokal) before the start of the full-scale war and after its start, differences in quality indicators and their dynamics were revealed, which is due to military operations and the destruction of facilities with the entry of pollutants into the water, changes in the intensity of industrial and agricultural production associated with the war and internal migration of the population. Since the state of water is affected by various factors, including weather and climate conditions, no clear relationship can be found that describes these effects, but the impact of military operations is quite obvious. Проблема. Воєнні дії негативно впливають на довкілля, зокрема на поверхневі води. Забруднення спричинені як потраплянням у воду техніки, озброєння, вибухових речовин та продуктів вибуху, так і потраплянням різних забруднювачів внаслідок руйнування об’єктів, очисних споруд та ін., а також змінами у процесах виробництва.Мета. Метою досліджень є порівняння якості поверхневих вод у річках, поблизу яких ведуться бойові дії у річках в тилових областях України за даними моніторингу.Методи дослідження. У роботі застосовано статистичні, порівняльні та аналітичні методи досліджень.Основні результати досліджень. Дослідження проведено за даними моніторингу вод річок Дніпро (м. Запоріжжя) та р. Західний Буг (м. Сокаль). Аналіз результатів моніторингу стану води за основними показниками якості дав можливість виявити наявність впливу між показниками якості води та періодом моніторингу – до початку війни та після її початку. Проаналізовано щомісячні дані моніторингу з 01.2021 по 10.2024 таких показників, як концентрація амоній-іонів, БСК5, розчиненого кисню, нітрат-іонів, нітрит-іонів, сульфат-іонів, фосфат-іонів та хлорид-іонів.Побудовано графіки залежностей, обчислено основні статистичні характеристики. Показники порівняли з гранично допустимими концентраціями, які встановлені нормативними документами.Наявність, характер та тісноту зв’язків визначили за коефіцієнтами кореляцій між відповідними показниками якості обох річок за весь період досліджень, період до початку війни і після її початку. Побудовано кореляційні матриці між показниками якості води кожної з річок у ці періоди. Виявлено відмінності поведінки показників, їх статистичних характеристик, а також кореляційних зв’язків.Висновки. За результатами моніторингу якості поверхневих вод р. Дніпро (м. Запоріжжя) та р. Західний Буг (м. Сокаль) до початку повномасштабної війни та...

In Ukraine, the tourism and recreation industry is widespread. These are mostly resort complexes with health boarding houses, hotels and restaurants. However, in Ukraine, the issue of solid household waste processing and active landfills, located near recreation facilities, is practically not...

The tourism industry is concentrated within the boundaries of the Subcarpathia Forestry District of Ukraine. These are mostly resort complexes with recreation houses, hotels and restaurants. Since the issue of solid household waste processing has not been resolved in Ukraine, landfills are...

Sustainable development includes the process of processing and recycling of solid waste. In Ukraine, a system of accumulation of solid waste without pre-processing in landfills has been formed. As a result, anthropogenically devastated landscapes have appeared in the country, causing...
