“…Migration of HM from ash and slag to the components of the ecosystem depends on many factors, one of the essential being the acidity of the environment. Earlier, we examined migration properties of heavy metals by developing concentration logarithmic diagrams (Buts Y., Kraynyuk O., Asotskyi V., 2020; Y. Buts, V. Asotskyi, O. Kraynyuk, 2019; Buts, Y., Asotskyi, V., Kraynyuk, O, 2018;Krainiuk O., ButsYu., 2018;Krainiuk O., ButsYu., Nekos A., 2019). Thus, one may assume that Cu, Ni, Zn and Cr are characterized by low mobility in soil, thus accumulating near the ash stockpiles, which is due to neutral and poorly-alkaline values of soil pH (рН=8,0…8,5).…”

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. To find ways to improve the soil properties of forest ecosystems after the action of the pyrogen- ic factor: to propose technological measures to restore the quality and improve the soil properties of the ecosystem; to prove the effectiveness of using clay in soil cleaning as a sorbent. Methods. The introduction of clay as a potential sorbent for cleaning fertile soils from trace metals is proposed. The mineral composition of the clay was determined by X-ray phase analysis. Clay materials can be successfully used in adsorption cleaning technologies. The method of phytoremediation with the help of dandelion to concentrate trace metal was used also. The concentration of trace metal was determined by atomic adsorption analysis. Results. The task of the experimental study was to substantiate the possibility of using cheap natural clay raw materials without its prior activation to remove trace metals from the soil solution. In the case of post-pyrogenic relaxation of ecosystems under conditions of man-caused load, the soil in the restored area may be contaminated with VM and other hazardous substances. The clay of the Kharkiv region was chosen for the experiment. The experiment proved the effectiveness of the use of clay in soil purification as a sorbent, and phytoremediation of dandelion in relation to heavy metals. Thus, both technical and biological methods of VM sorption to prepare the soil for planting can be recommended for the restoration of the forest ecosystem after a fire. The proposed technological measures to restore the quality and soil properties of the ecosystem include the implementation of design and survey work, including field research; implementation of the state ecological research (monitoring); cleaning the affected area from damaged trees; reclamation of soil fertility of regenerative territories, provided by design of restoration, depending on characteristic features of damages of sites and the subsequent application of regenerative territories. Conclusions. At postpyrogenic relaxation of ecosystems, in the conditions of technogenic loading, the efficiency of using clay in soil cleaning as a sorbent and phytoremediation with dandelion in relation to heavy metals has been proved.

“…Climatic and meteorological factors (humidity of air, atmospheric pressure, temperature) can lead to development of various inflammations of respiratory organs, exacerbations of chronic obstructive pulmonary disease, pneumonia, influenza and the like. The consequences of forest fires (Buts, 2018), geological factors, in particular the emission of Radon from the bowels of the Earth, can also provoke some diseases. For example, a Radon ejection is the second most important (after smoking) cause of lung cancer.…”

The article is devoted to consideration of the spatial-temporal structure of the primary morbidity and prevalence of the respiratory organs diseases among the population of the Sumy region. The article based on the data of annual statistical reports of medical institutions of Sumy region, which are subordinate to the Ministry of Public Health of Ukraine. The article used the methods of factor and correlation analysis, as well as methods of mathematical-statistical analysis, and ranking. The authors analyzed the spatial-temporal structure of respiratory organs pathology among the population and revealed the territorial differences and the dynamics of respiratory morbidity of the population. Nosogeographic assessment of territory of the Sumy region, which was carried out according to the integral respiratory diseases morbidity index (IMI), shows that today the highest values of IMI are obtained by analyzing the incidence rate in Putyvl’ (1.01), Krasnopillia (1.02), Konotop (1.11), Buryn’ (1.32) districts and in the city of Sumy (1.15). These are the districts where the incidence rate of respiratory diseases among the population has increased most of all during the study period. Low values of IMI are noted in Lypova Dolyna (0.63), Seredyna Buda (0.71), Velyka Pysarivka (0.72) and Nedryhailiv (0.79) districts. The higher is the IMI value, the worse the health level of the population. The average index storage respiratory diseases (ISD) in the Sumy region in 2017 was 1.27, with polarization ISD value in some areas from 1.19 in Shostka, 1.22 in Konotop, 1.23 in Yampil’ and Trostianets regions to 1.39 in Lebedyn, 1.42 in Romny and 1.61 in the Seredyna Buda districts. This indicates the predomination of chronic forms of diseases over acute ones and can be explained by the influence of environmental and socio-economic factors. It also points to the need to increase of attention of both the regional and state components of the health care system. Besides that, the issues of providing financial and human resources for the health care system in districts with high incidence rates of respiratory pathology require attention. The study of the primary morbidity and the prevalence of respiratory diseases trends is a prerequisite for the development of preventive measures in the Sumy region. They are also needed to assess the quality of medical care for residents who have the pulmonary diseases. The factor analysis results are confirmed the importance of environmental and technogenic factors in formation of the indicators of primary morbidity and prevalence of respiratory diseases among the residents of the Sumy region.
