Abstract. Currently, heavy metals are considered as priority soil pollutants. It is known that the vegetative mass of agricultural crops is capable of accumulating them in large quantities. Ornamental flower crops, which firmly occupy their ecological niche, are practically not considered from this point of view. The aim of this work is to study the features of the accumulation of heavy metals in the aboveground and underground organs of some representatives of the genus Paeonia L. in the urbanized environment of the city of Ufa. The objects of research were seven taxa of Paeonia (P. peregrina Mill., P. lactiflora Pall., P. lactiflora f. rosea, P. delavayi Franch., P. × hybrida Appassionata, Mustai Karim, Jeanne d’Arc). Methodology. The study of the elemental composition of the aboveground and underground parts was carried out according to the method No. M-02-1009-05 atomic spectroscopy. Mathematical data processing was carried out using generally accepted methods of variation statistics using the AgCStat software package in the form of an Excel add-in. Scientific novelty. For the first time, different taxa and parts of Paeonia plants were taken for research. Results. It was revealed that in the studied samples the copper content is 4,15–2520,00 times higher than that of other elements. It is noted that the minimum concentrations of arsenic, cadmium, chromium, manganese and iron are noted in the roots; lead and nickel – in flowers; copper – in the leaves of the studied paeonies. The maximum content of arsenic, lead, chromium is found in the leaves; cadmium, nickel, manganese – in the stems; iron – in flowers. That is, cutting paeonies in the autumn before retirement avoids the accumulation of these microelements in the soil. The results of the correlation analysis showed that the absolute values of the concentrations of the studied elements in the considered taxa of paeonies correlate with each other to a weak and medium degree. Correlation study of pairs of elements makes it possible to assess the synergism of accumulation and its absence, which is consistent with the opinion of other authors.

At present, heavy metals are generally recognized as priority soil pollutants, while the most active pollutants are their mobile forms, which can pass from solid phases into soil solutions and be absorbed by plants. It is known that the vegetative mass of agricultural crops is capable of accumulating large amounts of heavy metals. Ornamental flower crops, which firmly occupy their ecological niche, are practically not considered from this point of view. The aim of this work was to study the features of the accumulation of heavy metals in the aboveground and underground organs of some representatives of the genus Paeonia L. in the urbanized environment of the city of Ufa. The objects of research were four species ( P. peregrina Mill., P. lactiflora Pall., P. lactiflora f. rosea, P. delavayi Franch.) (Family Paeoniaceae Rudolphi) and three varieties of hybrid peony (Appassionata, Mustai Karim, Jeanne dArc). The study of the elemental composition of the aboveground and underground parts was carried out according to the method Determination of As, Pb, Cd, Sn, Cr, Cu, Fe, Mn and Ni in samples of food products and food raw materials by the atomic absorption method with electrothermal atomization. Mathematical data processing was carried out using generally accepted methods of variation statistics using the AgCStat software package in the form of an Excel add-in. Eight element studies are presented for each raw material group. Quantitative indicators of elements are given in mmol/kg of air-dry raw materials. It was revealed that in the studied samples the copper content was 4.152520.00 times higher than that of other elements. The minimum concentrations of arsenic (0.00350.0064 mmol/kg), chromium (0.00190.0046 mmol/ kg), manganese (0.01740.0219 mmol/ kg) and iron (0.00590.0125 mmol/ kg) were noted in the roots; lead (0.0030.037 mmol/kg), cadmium (0.00020.001 mmol/kg) and copper (0.14770.2134 mmol/kg) - in the leaves; nickel (0.00820.0179 mmol/kg) - in the flowers of the studied paeonies. The maximum content of arsenic (0.00620.0123 mmol/kg) and chromium (0.00280.0063 mmol/kg) was found in the leaves; lead (0.00270.0223 mmol/kg), nickel (0.01670.0209 mmol/kg), manganese (0.01730.0212 mmol/kg) and iron (0.00870.0138 mmol/kg) - in stems; cadmium (0.00020.0009 mmol/kg) and copper (0.1440.244 mmol/kg) - in flowers. Therefore, cutting paeonies in the autumn before retirement avoids the accumulation of these microelements in the soil. The results of the correlation analysis showed that the absolute values of the concentrations of the studied elements in the considered taxon of paeonies correlate with each other to a moderate and strong degree.

An artist who finds themselves in the last days of a war in the enemy’s defeated capital may not just fix its objects dispassionately. Many factors influence the selection and depicturing manner of the objects. One of the factors is satisfaction from the accomplished retribution, awareness of the historical justice triumph. Researchers think such reactions are inevitable. The article offers to consider from this point of view the drawings created by Soviet artists in Berlin in the spring and summer of 1945. Such an analysis of the German capital’s visual image is conducted for the first time. It shows that the above reactions were not the only ones. The graphics of the first post-war days no less clearly and consistently express other feelings and intentions of their authors: the desire to accurately document and fix the image of the city and some of its structures in history, the happiness from the silence of peace, and the simple interest in the monuments of European art.The article examines Berlin scenes as evidences of the transition from front-line graphics focused on the visual recording of the war traces to peacetime graphics; from documentary — to artistry; from the worldview of a person at war — to the one of a person who lived to victory. In this approach, it has been important to consider the graphic images of Berlin in unity with the diary and memoir texts belonging to both artists and ordinary soldiers who participated in the storming of Berlin. The combination of verbal and visual sources helps to present the German capital’s image that existed in the public consciousness, as well as the specificity of its representation by means of visual art.

The 20-30 years of the XX-th century in the history of Kazakhstan are characterized by the formation of such a form of governance of the republic from the center as the institute of emissaries. This form of management remained unchanged until the end of the Soviet period. The system of administrative management has acquired a new character, consolidating the former imperial positions based on the search for sources of raw materials and sales markets. The history of the formation and activity of the Institute of emissaries as a management system in Kazakhstan was not considered as an object of historical analysis. For the first time in the Kazakh historiography in the context of the 20-30s, the author analyzes the origins of the formation of this institute of management. The article highlights the beginning of a new stage in the Kazakh history, which implies a generalization of the activities of the power system and its nature from the point of view of modern realities.

Purpose. The research is devoted to the analysis of the agricultural exhibition pavilions symbolism in Dyukovsky Park in Odessa in 1950s years. Methodology. Field study and bibliographic research, synthesis and analysis, historical method, and method of analogies are used in that work. Results. The stages of Dyukovsky Park formation have been studied, from the Duke de Richelieu, which gave the name to the park, dacha creation to the active construction and landscaping of the park in the XX century. In particular, from the symbolism point of view, the architectural and artistic decor of the agricultural exhibition pavilions of the 1950s years is analyzed. These are: a pavilion of Vegetable growing which is crowned by layers of wheat and a 5-pointed star (the first place in the wheat export); the pavilion of the Textile Industry and other goods decorated with jugs and towels with symbols of fertility and abundance; the pavilion of the Vinery State Farms with plant motifs and the Fish Pavilion with high reliefs of fish, anchors, ship noses and bas-reliefs of nets (active development of sea fishing). In general, the symbolism of all presented pavilions reflects the idea of wealth, prosperity and active development of the main directions of agriculture and industry of the country. For the first time, the architectural heritage of the agricultural exhibition, which is the compositional core of the Odessa Dyukovsky Park, is analyzed from the symbolism point of view. At the same time, the decoding of the semantic loads inherent in the architectural and artistic decor of the pavilions is correlated with the theme of the exhibition, as well as with the historical features of the construction period. Today, all buildings of the former exhibition pavilions are empty or are used as warehouses. Perhaps the analysis of the information code of these buildings will again attract the attention of the city authorities to the issues of reconstruction of the city's historical heritage, reviving it.

in the conditions of the Kursk region, the analysis of soil samples and plant samples for the content of heavy metals was carried out. It is established that the soils of the studied areas are classified as having a high level of pollution in terms of their content. The priority pollutants of the soil are Pb, Zn, Cd, Cr, Ni, and Cu, the supply of which is mainly associated with the enterprises operating in this territory. The content of heavy metals in medicinal plant raw materials is estimated. For the first time, depending on the biological characteristics of Tilia cordata, Betula pendula, Plantago major, Urtica dioica, Achillea millefollium, data on the content of biologically active substances in conditions of technogenic pollution are presented, and the antioxidant activity of plants in areas characterized by various anthropogenic loads is studied.

Abstract For the first time, a survey about agricultural land focusing on the partitioning of the Pb, Cd, and Zn to the rural part of Mitrovica in northern Kosovo was made. Kosovo’s Mitrovica is one of the main industrial sites in the former Yugoslavia and a world-class mining district in Europe. The process of obtaining metals dates since 1927. From this year until 2000, the technological process of acquisition/obtaining has been accompanied by environmental pollution by creating waste landfills. These landfills are located on the outskirts of the city of Mitrovica at a distance from 1 to 4 km. In this area high levels of heavy metals in air, water, and earth were noticed. Therefore, these metal residues have a particular impact on air, earth, water, and effects on plants, animals and humans health. This situation became alarming; therefore in 2000 the production process was discontinued. During the period from 2000 to the present day, there is noticed a change of nature. Residents of the area have begun to work on agricultural lands without realizing the potential risk coming up. Despite the stagnation of industrial production, environmental pollution continues even further, especially from the landfill generated by industrial wastes. Widespread and very visible contamination mainly from Pb, Zn, Cd were found on the ground, with the highest concentrations measured near the Zveçan smelter. A significant amount of Cd, Pb, and Zn in contaminated soils/ground was quite movable/changeable, suggesting that these elements may be readily available for plants and soil/ground organisms. The main objective of this work is to address this pollution and take measures for education and information.

This paper examines the geographical description of Athens and Atlantis in Plato's dialogues Timaios and Critias. Plato described both Attika and the Athenian Acropolis essentially correct. The description of the Acropolis resembles the historical Acropolis of the Mycenaean time, but also the city of Athens of Plato's time. Plato's description of Atlantis is impossible from the geological point of view. Greek elements which appeared for the first time in the 7th century BC are included in the cultural description of Atlantis. The flood and cataclysms mentioned by Plato are based neither on Greek nor Egyptian tradition, but are based on his philosophical views.

AbstractThe study of potential possibilities of mesofauna as bioindicator of soil contamination by heavy metals is one of the most important areas of urban ecology and soil biology. The work presents the results of ecotoxicological and bioindicative assessment of the environment and the biota of the Melitopol urbosystem of Ukraine. The dynamics of chemical properties of soils in different functional zones of the city is analysed. The complex indices of pollution of environmental components are determined. A bioindicative assessment of the ecological condition of the territory of the urbosystem on the indicators of vitality of the soil mesofauna is carried out. For the first time, regional species-bioindicators for the territory of the city of Melitopol were determined. The ecomorphic structure of soil mesofauna of various functional zones of the city was revealed.

The growth of the essential oils market is explained by the growing demand for natural and organic products. Today, the global aromatherapy market with essential oils is growing, and demand for essential oils is increasing at the same rate. The studies are dedicated to the valuable essential oil culture ‒ fennel, the spread of which in the forest-steppe zone of Ukraine will allow to obtain high profitability by agro-forming of different forms of ownership and will help to provide the Ukrainian market with raw materials of appropriate quality. The article offers a solution to the pressing issue of expanding the area of new unconventional culture in the conditions of the Forest-Steppe of Ukraine by improving technological measures in the cultivation of culture. The basis of scientific research is the study of sowing terms (1st decade of April, for soil LTR 6-80C), (2nd decade of April, for LTR of soil 10-120C); row spacing (5, 30, 45 and 60 cm) and seeding rates (1, 1.5 and 2 million sprouting seeds per hectare). Among the plans of the research tasks were: to conduct the accounting of yields and to determine indicators of seeds quality (the content of essential oil in fennel seeds and its conditional yield per hectare of sowing), depending on the studied factors. Crop accounting was performed by continuous submerged threshing. The yield was brought to 100% purity and standard humidity according to the method described by V.O. Moiseychenko and V.O. Yeshchenko. Mathematical data processing was performed according to the method of B.A. Dopehova. The results of the research show that the sowing variants in the first decade of April, with a wide-row method (45 cm) sowing rate of one million sprouting seeds per hectare, yielded the optimum yield of fennel – 1.48 t / ha. In the same variant, the maximum content of essential oil was obtained – 6.23% and its yield from the hectare sowing area‒ 59.2 kg.
