Item Conceptual approach to the monitoring programme for the wetland of international importance Prut River Headwaters(2024) Korchemluk, Marta; Arkhypova, Liudmyla; Mykhailiuk, YuliiaFunctioning as a flood regulator and a freshwater reservoir, the Prut River Headwaters Wetland, protected under the Ramsar Convention, is a crucial hub of biodiversity, including endemic, rare, and threatened species listed in the national and global Red Lists. There are gaps regarding site management issues, including a lack of an integrated wetland monitoring system. Therefore, the objective of this research was to organise the processes involved in the comprehensive planning of wetland monitoring. To achieve this, the study utilised the conceptual framework for monitoring developed by the expert group of the UNESCO Chair on Sustainable Management of Conservation Areas. By employing the method of information-analytical research, a model for the water monitoring programme focused on the Prut River Headwaters Wetland was developed. A combination of physicochemical and hydrobiological assessments has been designed and partly tested. The method was used to test the universality of the proposed methodology in a specific studied area that requires sustainable management, and for the purpose of studying the perspective of application to other wetlands or valuable natural complexes in nature conservation areas. For the Conceptual Phase of the monitoring programme development, the key elements of river basin management of the Water Framework Directive of the European Union were used in synergy with the provisions of the Ramsar Convention. During the Implementation Phase, field and laboratory investigations of water bodies within the testing site at seven control points were conducted (measuring physicochemical parameters with portable equipment). All parameters’ values were within the limits of permissible norms. A primary database of results stored in the SMART software has been created. The practical implementation of the water monitoring plan is anticipated to contribute to the evaluation of the wetland ecosystem’s condition and support the administration of the Carpathian National Nature Park in the sustainable management of the wetland area.Item Impact of electric power facilities on natural phytocenotic diversity(2024) Glibovytska, Nataliia; Rashevska, Hanna; Arkhypova, Liudmyla; Adamenko, Yaroslav; Orfanova, MariiaThe relevance of studying the impact of electric power facilities on natural phytocenotic diversity lies in the necessity to preserve ecosystems due to the increasing number and size of electrical facilities, which potentially can affect the functioning of natural environments. The research aims to investigate the impact of electric power facilities on species diversity. The research is carried out at 46 monitoring sites in the immediate vicinity of the source of electromagnetic and noise pollution within the influence of the Burshtyn thermal power plant, the Bohorodchany solar power plant, the Shevchenkove wind power plant, the Tereble-Rytska hydroelectric power plant, under regional and cross-border power transmission lines. The representation of plant species at the monitoring sites is analysed. In general, 196 plant species are identified. Herbaceous plants dominate (from 74 to 100% of all plant life forms) at all monitoring sites, except for one site. Shrubs are present in 11 monitoring sites (from 5 to 25% of all plant life forms). The trees are represented in 20 monitoring sites (from 4 to 75% of all plant life forms). 179 species belong to the first class of constancy, 12 species belong to the second class and 5 species belong to the third class of constancy (91, 6.5 and 2.5%, respectively). The last plants have been identified as indicators of the influence of power plants. The most common plant families that exist under the influence of electrical installations are established. The largest number of species is represented by the Asteraceae, Rosaceae and Poaceae families – 37, 19 and 15 species, respectively. The species of the third constancy class have the highest representativeness. Daucus carota L., Achillea millefiolium, and Trifolium pratense L. are the dominant plant species in the areas impacted by electric power facilities. 180 species belong to the first constancy class. They cannot be suitable as phytoindicators of the ecological state in the areas affected by power plants. The results can be used to develop environmental protection strategies and measures to reduce the negative impact of power generation facilities on floraItem Mathematical modeling of pollution of underground aquifers due to mining of minerals(2024) Pukish, Arsen; Mandryk, Oleh; Arkhypova, Liudmyla; Syrovets, Serhii; Hryniuk, DianaPurpose. The research aims to create a mathematical model of salt contamination spreading through underground aquifers in the event of depressurization of the hydrocarbon production well crater for further assessment of environmental and economic damage from these processes. Methods. To predict the environmental and economic damage from salt contamination, the distribution of concentrations of harmful substances was investigated, taking into account the number of supply sources and their intensity over time, based on situ studies at the Rybalske Oil Field, Okhtyrskyi District of Sumska Oblast in Ukraine, where there were technological failures wells, accompanied by open fountains with the release of large amounts of highly mineralized water and the formation of craters. Mathematical modelling methods were used to process the data from the study of accidental technogenic pollution of underground aquifers. Findings. Based on real data from the study of the processes of potential salt contamination spread in fresh aquifers as a result of accidents at hydrocarbon production facilities, a mathematical model of salt contamination spreading in drinking groundwater in the event of depressurization of an oil field well crater has been developed. Potential economic losses in case of possible groundwater contamination with highly mineralized solution, which can into drinking groundwater aquifers, are substantiated. It has been established that in connection with the occurrence of an emergency situation due to the release of formation water to the surface in the territory of oil and gas fields, the formation of technogenic meromictic reservoirs is possible, which is confirmed by the example of the Rybalske Oil Field. It is proved that the total mineralization of crater water increases linearly with depth of the reservoir occurrence, and a similar dependence is characteristic of the chloride ion content. Originality. For the first time, a multicomponent mathematical model of mineral salt migration processes in underground freshwater aquifers in the case of depressurization of a meromictic reservoir has been developed. Practical implications. The research results obtained using numerical methods make it possible to predict the processes of spreading harmful substances in drinking underground aquifers as a result of emergencies at oil and gas fields, taking into account the number of sources of pollutants penetrating the study area, the heterogeneity of properties of the environment into which the harmful substance enters, and to assess the dynamics of changes in the concentration of these substances and time with further assessment of environmental and economic damage from these processes.Item Spatial-Temporal Patterns of Changes in PM 2.5 in Atmospheric Air of Ivano-Frankivsk Region(University "Vitez", 2024) Adamenko, S.; Arkhypova, Liudmyla; Adamenko, Yaroslav; Moskalchuk, N.; Glibovytska, NataliiaPM is one of the main atmospheric air pollutants causing serious concern for public health. Spatio-temporal patterns of PM 2,5 change are a current topic in physics atmospheric and environmental sciences. An equally important aspect is the study of the relationship between PM 2,5 concentration and meteorological characteristics.
