Strategies for Mitigating Seasonal Heavy Metal Release in River Sediments Using Natural Mineral-Based Materials Yuliia Trach, Olha Biedunkova, Maryna Kravchenko, Tetiana Tkachenko, Roman Trach Environmental Quality Management, 2026 This study presents an ecological and geochemical assessment of trace element contamination in the Huyva River (Ukraine), a right tributary of the Teteriv River that supplies drinking water to Zhytomyr and nearby settlements. The research involved monitoring key physicochemical parameters, including pH, mineralization, hardness, and major ion composition, to evaluate seasonal and spatial hydrochemical variations. Concentrations of trace elements in water and bottom sediments were analyzed for 2014 and 2024, covering Ba, Pb, Ti, Mn, Cr, Ni, V, Cu, Ag, Li, Cd, Co, and Zn. Pollution was quantified using Contamination Factor (CF), Contamination Degree (CD), Overall Pollution Index (Zc), and Geo‐accumulation Index (I geo ). The results revealed an increase in Mn, Cu, Pb, and Co levels in sediments and a general rise in overall pollution, attributed to anthropogenic activities, hydrological alterations, and climatic factors—notably higher temperatures and lower oxygen levels that enhance metal mobility. The study also evaluated potential stabilization strategies for heavy metals, including physicochemical, biological, and engineering methods. Among them, natural carbonate materials were identified as the most effective due to their environmental compatibility, affordability, and ability to operate near water intake areas without disturbing water treatment systems, supporting sustainable water quality management.
Analysis and Prospective Use of Local Mineral Raw Materials to Increase the Aesthetic and Recreational Value of the Vyzhyvka River (Western Ukraine) Yuliia Trach, Tetiana Tkachenko, Maryna Kravchenko, Viktor Mileikovskyi, Oksana Tsos, et al. Environments Mdpi, 2025 Macrophytes are important components of aquatic ecosystems performing essential ecological functions. Their species composition and density reflect the ecological status of water bodies. The optimal ratio of morphological types of macrophytes is an important condition for preventing eutrophication. The aim of the study is to analyse the species composition, distribution, and density of macrophytes in the Vyzhyvka River (Ukraine) in a seasonal aspect (2023–2024) under constant physical and chemical characteristics of water. To assess the seasonal dynamics of water quality, changes in indicators in three representative areas were analysed. The MIR method of environmental indexation of watercourses was used to assess the ecological state of the river. The water quality in the Vyzhyvka River at all test sites corresponds to the second class of the “good” category with the trophic status of “mesotrophic”. This is confirmed by the identified species diversity, which includes 64 species of higher aquatic and riparian plants. Among the various morphological types of macrophytes, submerged rooted forms account for only 10.56% of the total species composition. To ensure a functional balance between submerged and other forms of macrophytes, a scientifically based approach is proposed, which involves the use of mineral raw materials of local origin, in particular, mining and quarrying wastes rich in silicon, calcium and other mineral components. The results obtained are of practical value for water management, environmental protection, and ecological reclamation and can be used to develop effective measures to restore river ecosystems.
Gas Exchange Research on Plant Layers of Green Structures and Indoor Greening for Sustainable Construction Tetiana Tkachenko, Oleksii Shkuratov, Akif Fazil oğlu Qasımov, Viktor Mileikovskyi, Anna Moskvitina, et al. Sustainability Switzerland, 2025 Green structures, buildings incorporating living plants, offer numerous benefits, including carbon sequestration and improved indoor air quality. (1) However, the effective design and analysis of these structures are hindered by a lack of standardised methodologies. This work proposes a novel four-zone method for instantaneous gas exchange testing in green structures. (2) The method involves estimating gas exchange by measuring gas content at the plant zone’s entrance and exit, with individual CO2 content measurements within the zone to account for inertia and stratification effects exacerbated by mixing. (3) This method has been adopted into a national standard draft. The dependency of CO2 absorption/release is obtained for Chlorophytum comosum. The method is also successfully tested on Ligustrum vulgare. (4) The developed method provides formulas and data on CO2 absorption/release for use in designing green structures and indoor greening systems. Results show that Chlorophytum comosum can consume over 23 μg/s of CO2 per square meter of foliage, with a light saturation threshold for CO2 absorption between 8500 and 20,000 phlx, depending on CO2 levels.
Planning of green roofs for the best thermotechnical effect Tetiana Tkachenko, Anna Lis, Yurii Tsiuriupa, Viktor Mileikovskyi, Adam Ujma, et al. Scientific Review Engineering and Environmental Sciences, 2025 The energy-efficient provision of indoor comfort for buildings is one of the most important requirements for modern construction. The greening of buildings is a natural measure to achieve this, for which the most limiting factor is the lack of systematic research on its positive effects. At the Kyiv National University of Construction and Architecture, a series of research on thermotechnical benefits and gas exchange in plant layers has been performed. The cooling effect of plants is up to 4 K. Semi-intensive green roofs on rooms have paths, which absorb solar radiation and load the air-conditioning systems. The proposed solution is to build the paths on the auxiliary premises with low microclimate requirements. The work aims to estimate the heat distribution in green roofs with paths to test the recommendation. Simulation using the Fourier–Kirchhoff equation shows that the path has a trace of higher heat transfer on the ceiling up to an additional 1.8‒2.0 W·m−2. Thus, aligning the paths above the auxiliary premises is recommended, if possible. A better solution is to allow planting of the paths. Using plant-permit pavements and barefoot-in-dew systems such as ZinCo Soft Landscape are examples of such solutions. It is necessary to use grass that can be walked on.
ESTABLISHING PATTERNS IN ELIMINATING COAL FIRE SITES WITH NITROGEN-AIR MIXTURES Yuriy Tsapko, Tetiana Tkachenko, Oksana Kasianova, Аleksii Tsapko, Ruslan Likhnyovskyi, et al. Eastern European Journal of Enterprise Technologies, 2025 The object of this study was the value of nitrogen concentration at which the combustion process of anthracite is effectively inhibited. Therefore, the problem of eliminating the sites of self-ignition of coal relates to ventilating the pile with nitrogen, but it is necessary to take into account the required concentration of inert gas. It has been proven that on the basis of experimental studies of the process of inhibition of combustion when washing an anthracite batch with gaseous nitrogen, a sample of heated coal in a normal air atmosphere continues to burn with greater intensity. An increase in temperature by an average of 20 °C was recorded for 40–45 s. Adding nitrogen to the air in an amount of 12.85 % reduces the combustion temperature of anthracite by 2 %, but the cooling time of combustion below the ignition temperature exceeds 120 s. For a nitrogen-air mixture with a nitrogen concentration of 23.81 %, a decrease in the combustion temperature of the sample below its ignition for 120 s was recorded. Further increase in the amount of nitrogen in the nitrogen-air mixture to 28.57 % more effectively cools the combustion of anthracite below the ignition temperature for 70 s. The results showed that with an increase in the concentration of pure nitrogen in the nitrogen-air mixture, the requirements for the purity of nitrogen as a fire extinguishing agent increase. Therefore, it is necessary to introduce it into the i-th nitrogen-oxygen composition in such a concentration that the nitrogen content in the formed mixtures with air in both cases is the same. This is due to the fact that the purity of the nitrogen-oxygen mixture and its fire extinguishing concentration reflect the conditions under which there is the use of nitrogen-oxygen mixtures of a certain composition for fire extinguishing. The practical significance is that the results of determining the fire extinguishing concentration of nitrogen make it possible to establish the operating conditions of coal storage facilities during the elimination of fire sites
INNOVATIVE MEANS OF NORMALIZING PHYSICAL FACTORS THE ENVIRONMENT IN THE PROCESSES OF RECONSTRUCTION AND RESTORATION HISTORICAL HERITAGE OBJECTS Valentyn GLYVA, Larysa LEVCHENKO, Nataliia BURDEINA, Tetiana TKACHENKO, Grzegorz TWARDOWSKI, et al. International Journal of Conservation Science, 2024 The problems of reconstruction and restoration of historical buildings and structures are relevant all over the world. It is especially important for Ukraine, where a large number of historical buildings and buildings of architectural value have been destroyed or damaged by military operations. The developed composite materials allow, due to their small thickness, to reduce the levels of electromagnetic fields and noise to values that meet modern international standards. A particularly important result is the reduction of low-frequency noise levels (by 12–30dB), which is practically not absorbed by building materials and structures. LED sources ultraviolet radiation can be used in the presence of people for at least 8 hours without reaching the maximum permissible exposure level of 30J/m2 according to SBM-2015. The use of LED ultraviolet radiation sources allows to increase the concentration of ions in deionized air to the standard concentration (500 cm-3) within 10 minutes according to SBM-2015 and disinfect the environment.
Improving Urban Stormwater Management Using the Hydrological Model of Water Infiltration by Rain Gardens Considering the Water Column Maryna Kravchenko, Grzegorz Wrzesiński, Katarzyna Pawluk, Marzena Lendo-Siwicka, Anna Markiewicz, et al. Water Switzerland, 2024 Implementing rain garden (RG) designs is widespread worldwide to reduce peak flow rates, promote stormwater infiltration, and treat pollutants. However, inadequate RG design degrades its hydrological behaviour, requiring the development and validation of an appropriate hydrological model for the design and analysis of structures. This study aimed to improve a hydrological infiltration model based on Darcy’s law by taking into account the height of the water column (HWC) at the surface of the RG and the filtration coefficients of soil materials. The model was tested by simulating the hydrological characteristics of a rain garden based on a single rain event of critical intensity (36 mm/h). Using the validated model, design curves were obtained that predict the performance of the RG as a function of the main design parameters of the structure: water column height, ratio of catchment area to structure area, layer thickness, and soil filtration coefficient. The hydrological efficiency of the RG was evaluated in terms of the time of complete saturation, filling of the structure with water, and determining the change in HWC caused by changes in the parameters. The filtration coefficient and thickness of the upper and intermediate infiltration layers of the RG are the main parameters that affect the depth of saturation of the layers of the structure and the HWC on the surface. The model is not very sensitive to the model parameters related to the lower gravel layer. If the top layer’s thickness increases by 10 cm, it takes longer to fill the structure with water, and the HWC on the surface reaches 0.341 m. The rain garden’s performance improves when the filtration coefficient of the top layer is 7.0 cm/h. Complete saturation and filling of the structure with rainwater do not occur within 7200 s, and the water column reaches a height of 0.342 m at this filtration coefficient. However, the rain garden’s effectiveness decreases if the filtration coefficient of the upper and intermediate layers exceeds 15 cm/h and 25 cm/h, respectively, or if the catchment area to RG area ratio decreases to values below 15. The modelling results confirm that considering the HWC in RG hydrological models is essential for designing structures to minimise the risk of overflow during intense rainfall events.
Behaviour and Peculiarities of Oil Hydrocarbon Removal from Rain Garden Structures Maryna Kravchenko, Yuliia Trach, Roman Trach, Tetiana Tkachenko, Viktor Mileikovskyi Water Switzerland, 2024 The expansion of impervious areas in the context of climate change leads to an increase in stormwater runoff. Runoff from roads, petrol stations, and service stations is the most common form of unintentional release of petroleum hydrocarbons (PHs). Rain gardens are an important practice for removing PHs from stormwater runoff, but little data exist on the removal efficiency and behaviour of these substances within the system. The main objective of the study is to investigate the effectiveness of rain gardens in removing pollutants such as diesel fuel (DF) and used engine oil (UEO) in a laboratory setting, as well as to study the behaviours of these pollutants within the system. Eight experimental columns (7.164 dm3) were packed with soil (bulk density 1.48 kg/dm3), river sand (1.6 kg/dm3), and gravel. Plants of the Physocarpus opulifolia Diabolo species were planted in the topsoil to study their resistance to PHs. For 6 months, the columns were watered with model PHs followed by simulated rain events. The concentrations of PHs in the leachate and soil media of the columns were determined by reverse-phase high-performance liquid chromatography (RP-HPLC). The results of HPLC indicated the absence of UEO and DF components in the leachates of all experimental columns, which suggested 100% removal of these substances from stormwater. The chromatography results showed that 95% of the modelled PHs were retained in the surface layer of the soil medium due to the sorption process, which led to a change in hydraulic conductivity over time. Recommendations are proposed to increase the service life of rain gardens designed to filter PHs from stormwater.
Improving the Efficiency and Environmental Friendliness of Urban Stormwater Management by Enhancing the Water Filtration Model in Rain Gardens Maryna Kravchenko, Yuliia Trach, Roman Trach, Tetiana Tkachenko, Viktor Mileikovskyi Water Switzerland, 2024 Rain gardens are used to solve urban problems related to the negative impact of stormwater. (1) Scientific contributions from different countries provide general guidelines for the design and operation of rain gardens in different geographical areas. Given the small spatial scale of rain gardens, the use of existing infiltration models often leads to design errors. (2) The purpose of this paper is to develop a hydrological model by introducing a system of equations that extends the ability to calculate the rate, flow rate and time of saturation of layers with moisture and rainwater leakage from the rain garden system. (3) The results obtained allow us to describe the dynamic processes of passage and saturation of layers of the rain garden at a certain point in time, which extends the ability to calculate the flow rate. It was established that the smaller the area of the rain garden compared to the area of the catchment basin, the faster it reaches its full saturation. Increasing the thickness of the rain garden layers allows for an increase in the efficiency of water retention at a lower value of the area ratio. (4) The practical significance of the results obtained is especially important for the correct description of hydrodynamics in the system and determining the optimal conditions for the effective functioning and management of the rain garden structure for any climatic region.
