The purpose of this research is to analyze the characteristics of heatwaves during the warm period of the year as a manifestation of climatic changes in Ukraine. It was also our goal to establish how reliable Heat and Cold Wave Index (HCWI) from European Drought Observatory (EDO) is as a tool for heatwaves analysis. To extract the frequency and duration of heatwaves the percentile thresholds of 90 th were used. The data from Ukraine' weather stations since 1980 to 2021 were under analysis. There are 83 heatwave (HW) recorded in Ukraine. At the same time, for the first half-period 29 events of heatwaves were recorded, and for second half-period (2001-2021) − already 54 events. The duration of heatwaves increased during the study period. If for 1980-2000 the average duration of the heatwaves was 3.8 days, then for 2001-2021 the average duration increased to 4.3 days. The average maximum length of heatwaves increased more significantly − from 7.4 to 11.5 days in the second half-period. The intensity of heatwaves was evaluated by temperature extreme. The average maximal temperature during the heatwaves over Ukraine is 32.2ºC. The hottest HW event for the study period had maximum daily temperature of 41.4ºC (2010). For the first time, HCWI was used to determine the frequency, duration and intensity of heatwaves in Ukraine. HCWI can also be applied to study climate changes, determine the period of droughts, the adaptation of the population to heat stress and the healthcare system to its consequences.

The objective of the study was the composition of ash and slag waste from the Zmiiv TPP (thermal power plant) and the peculiarities of migration of heavy metals (HM) from the place of storage of ash and slag waste into the ecosystem. To achieve this goal, the following tasks were solved: chemical analysis of ash and slag waste of the Zmiiv TPP; identification of the probability of HM migration into the soil environment in the places of ash and slag waste storage. Ash and slag of the Zmiiv TPP contain Cu, Cr, As, Cd, Ni, Pb in quantities several times higher than the threshold limit value (TLV). For ash and slag wastes, the total pollution rate was Zc = 43, which corresponds to a high level. That is, this artificial horizon is dangerous. HMs migrate to groundwater and soils near the ash stockpiles as a result of infiltration of precipitation waters, leaks from water-bearing communications, water filtration through the base of the ash stockpiles of the Zmiiv TPP. To determine soil contamination near the ash stockpiles, we analyzed soil at the distances of 0, 5, 10, 50 and 100 meters. The contents of the HM decreased further away from the stockpiles. At the distance of up to 100 meters from the dump, there were excesses of the threshold limit values for Ni, Cu, As, Cr in the soil. The concentration factor exceeded one for Cr, As, Cu, Cd, Ni. Only at the distance of 100 meters did the contents of Pb and Zn reached the background values. The calculation of the total rate of soil contamination allowed us to classify these soils as moderately dangerous and acceptable. However, the Zn indicator has several significant disadvantages, particularly it does not take into account the differences in the potential hazards of the elements, as well as, most importantly, the synergistic effects of polymetallic pollution. The coefficient of synergistic effect of heavy metals was 26.64 (in the soil of the ash stockpiles), then decreased, but even at the distance of 100 meters it equaled 11.23, i.e. at the distance of 0... 100 m from the ash stockpiles, the overall actions exceed the norm. The study revealed that Cu, Ni, Zn and Cr had low mobility in the soil near the ash stockpiles and therefore accumulated near the stockpiles, which may be explained by neutral and slightly alkaline soil pH values. The ratio of mineral phases and glass varied, but we should note the predominance of aluminosilicates, calcium silicates and glass in the ash and slag wastes. Heavy metal compounds are confined mainly to amorphized clay aggregates and soot-coal ash formation, to a lesser extent to slag glass and even less to grains of quartz sand. Since ash contains such fractions that can be easily carried by the wind, it should be assumed that ingress of HM into the ecosystem occurs by air, which also contributes to air pollution. The solution to the problem of ash and slag waste disposal can be found in their utilization in the production of construction materials, in road construction, but it is necessary to study the composition of ash and slag and the probability of migration of HM depending on the conditions of use.

Purpose. The aim of the study is to analyze the geochemical composition of ash and slag waste at the Zmiiv Thermal Power Plant (TPP) and to identify the features of migration of heavy metals (HM) from the place of storage of ash and slag waste into the ecosystem. To achieve this goal, the following tasks were solved: geochemical analysis of ash and slag waste at Zmiiv TPP; study of the reliability of HM migration into the soil in the places of ash and slag waste storage. Methods. The content of heavy metals in ash, slag and soil were investigated using atomic absorption analysis (AAA) on a spectrophotometer S-115. X-ray diffraction analysis was used to determine the solid inorganic part of ash and slag. Results. Ash and slag of Zmiiv TPP contain Cu, Cr, As, Cd, Ni, Pb in quantities that are several times higher than the maximum permissible concentration (MPC). For ash and slag waste, the total pollution index is Zc = 43, which corresponds to a high level. That is, this artificially created horizon is dangerous. HM migrate into groundwater and into the soil near the ash dump due to the infiltration of atmospheric precipitation, emissions from water pipelines, filtration of water through the base of the ash dump of the Zmiiv TPP. To determine soil contamination near the ash dump, soil analyzes were performed at a distance of 0 ... 100 meters. At a distance of up to 100 meters from the dump, there is an excess of MPC in the soil for the content of Ni, Cu, As, Cr. At a distance of up to 100 meters from the dump, an excess of the MPC in the content of Ni, Cu, As, Cr is observed. Concentration factor exceeds unity for Cr, As, Cu, Cd, Ni. The content of Pb and Zn reaches background values only at a distance of more than 100 meters. The calculation of the total soil pollution indicator allows us to classify these soils as moderately hazardous and permissible. However, there are several significant disadvantages of the Zc indicator. First of all, it does not take into account the differences in the potential hazard of chemical elements, and, most importantly, the synergistic effects of polymetallic pollution. The coefficient of the synergistic effect of heavy metals is 26.64 (in the soil of the ash dump), then it decreases, but even at a distance of 100 meters it is 11.23, that is, at a distance of 0 ... 100 m from the ash dumps, the condition of the coefficient of synergistic effect is less than one. It has been established that Cu, Ni, Zn and Cr are characterized by low mobility in the soil near the ash dump, therefore they accumulate in the ecosystem near the ash dump, which is explained by the neutral and slightly alkaline soil pH values (pH = 8.0 ... 8.5). The ratio of mineral phases to glass is unstable; however, it should be noted that aluminosilicates, calcium silicates and glass predominate in ash and slag. Сompounds with HM are confined mainly to amorphous clay aggregates and sooty-carbon formations of ash, to a lesser extent to slag glass and even less to grains of quartz sand. Conclusions. Since the ash contains such fractions that can be easily carried by wind, it should be assumed that the HM entry into the ecosystem is also by air, which also contributes to air pollution. The solution to the problem of ash and slag waste disposal should be found in the production of building materials, in road construction, but it is necessary to study the composition of ash and slag and the probability of HM migration depending on the conditions of use.
