M.; Popovych, V. V.; Bosak, P.V.; Shuplat, T. I. Abstract: Purpose. To study ecological regularities of the formation of vegetation cover in Ukraine depending on the climatic conditions and analyze its possible changes due to global warming. Methodology. The research methodology involves the following: diff erentiation of the climatic conditions and evaluation of the signifi cance of climatic indices at the level of territorial units of a geobotanical zoning based on variance analysis; multiple ordering of the geographic locations in terms of climatic indices basing on the analysis of main components (Principle Component Analysis); development of a typological scheme of the vegetation cover relying upon a discriminant analysis; statistic processing of the climatic parameters. Findings. Modelling of spatial diff erentiation of climatic indices depending on the location latitude and longitude as well as altitude above the sea level helped analyze the connection of vegetation cover and climate. It has been determined that peculiarities of the vegetation cover formation according to a scheme of geobotanical zoning is characterized in the most accurate way by the diff erence of such climatic indices as: air temperature in January, July, and August; monthly precipitation amounts during June September; duration of a frost-free period; and hydrothermal coeffi cient of T.G. Selianinov. The main regularity of the formation of Ukrainian vegetation cover has been defi ned. The regularity means the following structure of interrelation between the climatic indices: along with the growing average monthly temperatures of June-September and decreasing precipitation amounts from April to September, the indices of climatic water availability decrease along with the increasing heat availability indices (duration of an active vegetation period and total of temperatures per that period, average annual temperature). This regularity represents a gradient of climatic indices from the Ukrainian Carpathians towards the southern Crimean coast. It has been determined that during some years of the early 21st century, the conditions peculiar for a steppe area were formed for the forest and forest steppe areas. Originality. The vegetation cover of Ukraine is characterized by the ecological range, which is evaluated basing on ordering of the geographical locations in terms of coverage of complex climatic environmental gradients. A typological scheme of the Ukrainian vegetation cover can be represented in a two-dimensional space in the form of square parabola, whose left branch shows a gradient of climatic factors and changes in vegetation cover from the west to the north-east and right branch indicates it from the north-east to the south. Graphic visualization of climatic information on the basis of ecograms and typological schemes of vegetation cover can be used to predict the vegetation cover dynamics due to certain climatic changes. Practical value. While understanding the climatic conditions of geographic locations during certain periods of time, one can identify their location in the ecological and coenotic range of Ukrainian vegetation and predict their stability and possible changes in the vegetation cover due to global warming. 2022-01-01T00:00:00Z https://sci.ldubgd.edu.ua/jspui/handle/123456789/14541 Title: Monitoring of Heavy Metals Migration intoEdaphic Horizons of Coal Mine Dumps Authors: Popovych, Vasyl; Voloshchyshyn, Andriy; Tyndyk, Oleh; Menshykova, Olga; Shuplat, Taras; Bosak, Pavlo Abstract: Abstract. Mining of minerals is accompanied by direct irreversible changes in the biosphere. An analysis of the latest researches on the technogenic hazard of rock dumps at coal mines, as well as specifics of their reclamation and phytomelioration in a global context, necessiates the study of the ecological state and natural phytomelioration of the Nadiya mine waste heap in the Lviv-Volyn coal basin (Ukraine). This scientific work presents the results of research on heavy metals migration into the genetic horizons of the rock dump, as well as their influence on forming the phytomeliorative cover on its surface. It has been revealed that the studied site of the No.4 rock dump in the 0-15 cm horizon, which is located from the eastern side near the foot, is the most contaminated with heavy metals. The indicators of heavy metal content at the background site, which is located within a radius of 3 km from the rock dump, are the lowest in the 0-15 cm horizon. The uneven distribution of heavy metals in the genetic horizons of the rock dump substrate is caused by frequent landslides, changing rock acidity, heterogeneity of natural overgrowth, and existing combustion sources. In the event of precipitation, toxic compounds, heavy metals and other harmful substances are washed out from the rock dump surface, and in our case, these substances also enter the natural water body 2022-10-01T00:00:00Z https://sci.ldubgd.edu.ua/jspui/handle/123456789/14539 Title: Chemical Content of Landfill Neoreliefs in the Territory of the Subcarpathia Forestry District of Ukraine Authors: Korol, Kateryna; Popovych, Vasyl; Pinder, Volodymyr; Shyplat, Taras; Bosak, Pavlo Abstract: 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 emerging near recreation facilities. Undoubtedly, such a situation contradicts the improvement processes, because landfills are objects of detonation of dangerous substances and compounds infiltrating into all components of the environment due to geochemical flows. The object of the conducted research was determination of chemical elements in the newly formed substrates on the surface of the following landfills, i.e. Bronytskyi, Stryiskyi, Boryslavskyi, which are located not far from the border with Poland within the tourist and recreational complex of the Lviv region of Ukraine, geographically belonging to the Subcarpathia Forestry District of Ukraine. It was established that the chemical elements of the toxic group and biogenic elements accumulate. The traces of individual elements were also determined. The Bronytskyi landfill is the most polluted with the following chemical elements: Pb (3.56–4.06 mg/kg), Zn (2.84–3.67 mg/kg), Gd (0.021–0.033 mg/kg), P (457.3–609.7 mg/kg), K (9.7–14.6 mg/kg), Ca (174.7–237.7 mg/kg), Ga (3.58–5,98 mg/kg), La (1.09–1.24 mg/kg), Y (0.013–0.014 mg/kg), Cd (0.15–0.176 mg/kg), Sn (0.013–0.018 mg/kg), Nd (0.029–0.046 mg/kg), Eu (0.022–0.036 mg/kg) and Th (0.05–0.078 mg/kg). The site of the Boryslav landfill is most polluted in the western side - Fe (16.06–19.72 mg/kg), Cu (0.37–0.43 mg/kg), Gd (0.003 mg/kg), Si (43–58.2 mg/kg), P (782.4–995.5 mg/kg), Ca (88.6–104.7 mg/kg), Mn (1.7–2.7 mg/kg), Sc (0.009 mg/kg), Cr (1.069–1.255 mg/kg), Y (0.015–0.016 mg/kg), Nd (0.016–0.018 mg/kg). In the eastern side of the Stryi landfill the presence of the following elements is most evident - Fe (18.98–27.97 mg/kg), Ni (0.09–0.21 mg/kg), Zn (0.14–0.19 mg/ kg), Pb (0.05–0.1 mg/kg), Al (1.6–2.0 mg/kg), P (718.1–652.5 mg/kg), Mn (2.5–3.5 mg/kg), Ga (0.01 mg/kg), La (0.02–0.04 mg/kg), Cr (0.009–0.013 mg/kg), Ge (0.214–0.551 mg/ kg), Cd (0.014–0.02 mg/kg), Nd (0.017–0.037 mg/kg), Th (0.009–0.016 mg/kg). Such a detailed chemical analysis for the presented research objects was carried out for the first time. Determining of the chemical content of the newly formed substrate is important from the point of view of environmental protection solutions implementation. 2022-11-11T00:00:00Z https://sci.ldubgd.edu.ua/jspui/handle/123456789/14506 Title: Wastewater Purification from Excess Phosphates Using Bentonite Activated by Microwave Radiation Authors: Boichuk, Bohdan; Kuzyk, Andrew; Sysa, Leonid; Pastukhov, Paul; Shuplat1, Taras Abstract: This article examines the possibilities of improving the ecological condition of small rivers on the example of the upper part of the Prut River in the vicinity of Yaremche (Ivano-Frankivsk region, Ukraine). The previously published data of the article authors and other researchers that the amount of pollutants in river water in this area has increased, in particular, phosphorus compounds, has been confirmed. It was shown that the incompletely purified wastewaters of Yaremche, which contains an excess of phosphate ions, has a significant impact on this fact. On the basis of their own previous research and current work, the authors propose removing these ions using a natural sorbent based on bentonite, activated by microwaves in various ways. Experiments have shown that microwave activation of this sorbent increases the coefficient of phosphate ions extraction from wastewater significantly higher compared to natural bentonite. An approximate technological scheme of wastewater purification from excess phosphates after the main standard purifying cycle was suggested. 2022-03-01T00:00:00Z
