Complex chemical-analytical and microbiological studies of the state of water, soil grounds and bottom sediment of the industrial zone of city of Khabarovsk were carried out. It was found that petroleum prodacts are the main environmental pollutant of the study area. The impact of runoff from the industrial zone on the quality of water and bottom sediments of the Amur river is manifested in an increase in their content and number of indicator groups of bacteria in the zone of impact of the small river Kurcha-Murcha draining the territory of the industrial zone. The oil content in the Kurcha-Murcha river at the exit from conduit is 20 MPC. The degree of soil contamination varies from “increased-background” to “strong”. The amount of oil products in the bottom sediments of the Kurcha-Murcha and the Amur river (below the mouth of the Kurcha-Murcha river) is defined as "dangerous" and "strong", respectively.

В условиях антропогенного воздействия на окружающую среду и несбалансированного природопользования может происходить снижение самоочищающей способности реки Амур и ухудшение качества воды. Водопользование в бассейне реки осуществляется со стороны трёх государств: России, Монголии и Китая. Основными источниками поступления загрязняющих веществ в Амур с российской стороны являются предприятия деревообрабатывающей промышленности, машиностроение, цветная металлургия, добыча полезных ископаемых, производство электроэнергии. Снижение качества воды происходит также за счет недостаточной степени очистки сточных вод. Трансграничное положение изучаемого водного объекта, разница демографических потенциалов России и Китая и активное техногенное воздействие со стороны сопредельных территорий обусловливает актуальность настоящего исследования, целью которого является оценка многолетней изменчивости химического состава и качества воды на протяжении реки Амур. Исследование проведено на основе многолетних (20002017 гг.) гидрохимических данных Государственной системы наблюдений за состоянием и загрязнением окружающей среды Росгидромета в пунктах наблюдений на р. Амур: с. Черняево, гг. Благовещенск, Хабаровск, КомсомольскнаАмуре и НиколаевскнаАмуре. Рассмотрен химический состав воды на различных участках реки и проведена оценка качества воды по гидрохимическим показателям. Построены графики временной изменчивости значений удельного комбинаторного индекса загрязненности воды (УКИЗВ). Анализ многолетних данных показал, что на всех исследуемых участках реки концентрации хлоридов, сульфатов и нитратов не превышают предельно допустимые концентрации. Выявлены характерные загрязняющие вещества, содержание которых превышает нормативы ПДК более, чем в половине случаев. Это органические вещества, азот аммонийный, соединения железа, меди, цинка, никеля, марганца, фенолы и нефтепродукты. Наблюдается увеличение содержания некоторых загрязняющих веществ вниз по течению реки. В целом качество воды реки Амур на различных участках характеризуется 3м ( загрязненная и очень загрязненная ) и 4м классами качества ( грязная ). В динамике выражена общая положительная тенденция незначительного снижения уровня загрязненности воды.The title of the article is longterm variability of chemical composition and quality of water along the Amur river. As the title implies the article describes the chemical composition of water in different parts of the river and the water quality by hydrochemical parameters. A mention should be made that under the conditions of anthropogenic press on the environment and unbalanced use of natural resources, the ecological potential of the water ecosystem of the Amur River is depleted and the quality of water decreases. The transboundary position of the studied water object, the difference in the demographic potentials of Russia and China determines the relevance of this paper. The purpose of the work is to assess the longterm variability of the chemical composition and water quality along the Amur River. It should be noted that this research is based on longterm (20002017) Hydrochemical information. The state system of observers for the state and environmental pollution of Roshydromet at observation points along the river: c. Chernyaevo, the city of Blagoveshchensk, Khabarovsk, KomsomolskonAmur and NikolaevskonAmur. As a result, the analysis of longterm data showed that the concentrations of chlorides, sulphates and nitrates do not exceed the maximum permissible concentrations on all the studied river sections. Identified characteristic pollutants, the content of which exceeds the MPC standards in more than half of the cases. There is an increase in the content of some pollutants downstream of the river. In general, the water quality of the Amur River at different sites is characterized by the 3rd (polluted and very polluted) and 4th quality classes (dirty).

The climate of the planet is a complex system that changes as a result of processes of interaction between the atmosphere, the ocean and man. These elements are in a balanced equilibrium, which is now being destroyed by man's human activity. The urgency of the theme is due to the necessity of determining changes in the hydrological, hydrochemical and hydroecological state of water objects of Ukraine in the conditions of anthropogenic influence and global warming in order to optimize the management of water resources. The purpose of the research is to study the impact of climate change on the quality of water resources of Psel river, depending on the temperature regime and rainfall in Poltava region. The paper examines the effects of global warming, namely changes in the temperature regime of air and rainfall on qualitative and quantitative characteristics of Psel river in the territory of Poltava region. Using statistical methods, the existence of a correlation between climate parameters and qualitative characteristics of the reservoir has been proved. The results of the research should be taken into account when developing the schemes of adaptation of the region to the conditions of global warming and in the management of water protection activities in the basin of Psel river. The practical value of the results is to provide estimates of changes in the characteristics of the water resources of Psel river; detecting the effects of climate change on the hydrological, hydrochemical and hydroecological regimes of the river; establishing interrelationships between raising the average annual water temperature and the oxygen regime of the reservoir. The results of the work in the future will be used in the development of regional environmental programs and schemes for optimizing the management of water resources.

The impact of floods on the migration activity of elements coming from urbanized territories to the Amur river was assessed. The influence of large cities on pollution of water and floodplain ecosystems is revealed. The content of heavy metals in water, bottom sediments, and small watercourses draining urban areas is characterized. The processes of sediment accumulation in the floodplain, their influence on the redistribution of elements and geochemical transformations in the soil space of floodplain soils are studied. Conditions for the accumulation of heavy metals in soils are described, their concentration levels and migration activity are determined. The role of organic matter in swamps and silts on water pollution and bottom sediments of the Amur river is shown. It was found that the main mass transfer of soluble substances and pollutants dispersed fractions of nailc is carried out by water flow during floods.

A growing number of urban interventions, such as culture-led regeneration strategies, has emerged alongside growing awareness of the concept of re-urbanization. These interventions evolve to create a holistic urban vision, with aims to promote social cohesion and strengthen local identity as opposed to traditional goals of measuring the economic impact of new cultural developments. Szczecin’s, Poland urban strategy is focused on the expansion of culture—a condition for improving the quality of life and increasing the city’s attractiveness. This article assesses the potential for re-urbanization of Szczecin’s flagship cultural developments. Questionnaire surveys and qualitative research methods were used to assess the characteristics that distinguish cultural projects in the formal, location-related, functional, and symbolic layers, as well as examining their social perception. The results show that the strength of these indicators of urbanscape identity affects how the cultural developments are assessed by the society. Semiotic coherence and functional complexity of the structures have a significant impact on the sense of identification, while their monumentality and exposure contribute to the assessment of the impact on their surroundings. A development with a firm identity, embedded in the city’s tradition not only preserves the cultural heritage of the city but also makes inhabitants feel association with the new project.

Much of the earth’s surface is covered by water. As was pointed out in the 2020 edition of the World Water Development Report, climate change challenges the sustainability of global water resources, so it is important to monitor the quality of water to preserve sustainable water resources. Quality of water can be related to the structure of water crystal, the solid-state of water, so methods to understand water crystals can help to improve water quality. As a first step, a water crystal exploratory analysis has been initiated with the cooperation with the Emoto Peace Project (EPP). The 5K EPP dataset has been created as the first world-wide small dataset of water crystals. Our research focused on reducing the inherent limitations when fitting machine learning models to the 5K EPP dataset. One major result is the classification of water crystals and how to split our small dataset into several related groups. Using the 5K EPP dataset of human observations and past research on snow crystal classification, we created a simple set of visual labels to identify water crystal shapes, in 13 categories. A deep learning-based method has been used to automatically do the classification task with a subset of the label dataset. The classification achieved high accuracy when using a fine-tuning technique.


The quality of surface water remains an important issue today. This is particularly acute for water bodies located in the urban-basin geosystems. Purpose. To estimate pressure of atmospheric precipitation within the urban landscape basin geosystem on the river water (by example of the Kharkiv river). Methods. Field landscaping, ecological, landscape-geochemical; analytical; system analysis; chemical analytical; statistical Results. An assessment of the state of surface waters under the impact from the surface runoff of atmospheric origin during 2014-2016, and partly from 2017-2019, formed under the influence of the transport (partly residential) subsystem of the urban area and surface waters in Kharkiv. On the salt content, the characteristic of water quality is "moderately polluted" (1,6); on the tropho-saprobiological indicators, the quality of water is characterized as "polluted" (from 3.1 to 2.75 along the river). It is in this context the impact of waters, which is formed in the conditions of the urban environment for the quality of natural waters, is well demonstrated. The presence of high values of pollutants and natural factors. The assessment of the quality of water on the content of specific indicators is "moderately polluted" (from 2.28 to 1.85). Conclusions. The water of the Kharkiv region, which has a strong influence from the urban environment, has a grade III quality; the water is "moderately polluted". Environmental assessment indicates the impact of surface runoff already on the middle part of the river, which increases in accordance with the conditions of the operation of urban landscapes and anthropogenic (transport) load.

This paper presents the assessment of the impact of coal ash and slag from the ?Maljevac? dump on the quality of water of Paleski Creek, Montenegro. The obtained results confirm the negative influence of surface and groundwater from the dump on the water from the Paleski Creek. The results obtained by testing of the water samples, collected from Paleski Creek upstream of the dump, indicate that the water is qualified to be used for drinking, after simple physical treatment and disinfection. The results obtained for the water samples collected from the Paleski creek downstream from the dump indicate that the water could be safe for drinking only after the treatment that requires an intensive physical, chemical and biological processing, including some extended treatment.
