The Impact

Anthropogenic pollution of water basins may become a serious threat for ecosystems and human health. Pollutants are transferred through food chains or directly when untreated water is used, released to soil through subsoil waters or during floods. The increased anthropogenic load on rivers’ hydrosystems, especially in their del-tas, is becoming rampant these days. The goal of the research is to study the coastal areas and to assess the state of vegetation. To achieve this goal, standard methods of biotesting and bioindication were applied in the territories of two water-protection zones – those of the Volga River and the Nozhovskiy erik (shallow channel in the Volga delta – translator’s note) near the Ilyinka village. The water quality in the Volga River, within the examined range, is stably characterized as “dirty” (4th class). The exceeded level of maximum permissible concentrations for petroleum products, heavy metals (mercury, zinc, molybdenum), sulfides and phenols is observed. The research has not revealed the impact of the quality of water on phytotoxicity of the soil and indices of abundance of the vegetation that grows in this territory. Toxicity of soils is weak in the area of the Nozhovskiy erik, it is very weak in the area of the Volga River: the germination capacity of the test object (watercress) ranges between 67 and 88%, morpho-metric indices of plants do not differ much from those in control groups. Within the summer period the monitoring sites were characterized by the maximum frequency-abundance indices of typical representatives of the local flora, which are camel thorn (Alhagi pseudalhagi) and greater burdock (Arctium lappa). Vegetation in these areas is abundant, its state is assessed as satisfactory.

The Yamal Peninsula

Most of the population of the Yamal Peninsula lives in settlements located on the banks of rivers. The increasing industrial development of the Yamal Peninsula leads to the fact that in these settlements in the water area and on the shores, objects of the fuel and energy complex are being built and functioning. At the same time, the contribution to water pollution of settlements located here, as well as objects of transport and fuel and energy infrastructure, is still unclear. On the other hand, the issues of intensifying the processes of coastal destruction and the related danger to residential and economic infrastructure are increasingly being discussed. However, the degree of activation of these processes on the Yamal Peninsula is also poorly understood. During the study, the state of water bodies and water protection zones was monitored for the period from 2016 to 2020. It was found that at present no significant anthropogenic pollution of water and bottom sediments is recorded. The content of pollutants and heavy metals is mainly determined by natural conditions. At the same time, the water protection zones are littered with scrap metal and household waste. Activation of channel processes and processes of abrasion and thermal abrasion of the banks is observed. The intensity of coastal destruction processes in the erosion zone varies from 0.25 to 0.85 m/year.

Выполнен анализ действующей редакции Методики разработки нормативов допустимых сбросов веществ и микроорганизмов в водные объекты для водопользователей , утвержденной приказом Минприроды России от 17 декабря 2007 г. 333, на предмет непротиворечивости и соответствия нормам водоохранного законодательства. Выявлена неопределенность применения Методики в условиях воздействия на качество воды природных и антропогенных факторов, не зависящих от конкретного водопользователя. Положения Методики противоречат принципам нормирования воздействия на водные объекты на основе наилучших доступных технологий, что было показано на примерах утвержденных технологических показателей содержания загрязняющих веществ в сточных водах различных отраслей промышленности. Анализ системы нормирования допустимых воздействий на водные объекты и географической дифференциации нормативов качества воды в пределах Российской Федерации вместе с системой целевых показателей качества воды также показал несоответствие Методики основным принципам водоохранного законодательства.The analysis of the current edition of the Methods of developing standards for permissible discharges of substances and microorganisms into water bodies for water users , approved by the Order of the Ministry of Natural Resources of Russia dated December 17, 2007 No. 333 for consilience and compliance with the regulations of the water protection legislation, is carried out. Uncertainty of the application of the Methods in the conditions of the impact of natural and anthropogenic factors that are independent of a specific water user on the quality of water has been identified. The provisions of the Methods contradict the principles of regulating the impact on water bodies based on the best available technologies shown on the examples of approved process indicators of the concentrations of various industrial pollutants in wastewater. An analysis of the system of regulating the permissible impact on water bodies and the geographical differentiation of water quality standards within the boundaries of the Russian Federation, together with the system of water quality targets, also showed that the Methods do not comply with the basic principles of the water protection legislation.

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.

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 article describes the ecological state of the Ural River at the present stage. Hydrochemical regime of the reservoir is an important indicator to regulating the number of water resources. As the Ural River is the transboundary reservoir, it is prone to contamination from various areas in the upper and middle reaches. Monitoring of the ecological state of the Ural River showed the presence of anthropogenic pollution. The hydrochemical regime of the reservoir is subject to changes in seasonal variations in water composition. In spring, with flood waters, the main pollution enters the river, however in other seasons, the quality of water leaves much to be desired. In autumn, in comparison with the spring, both alkalinity and salinity increased. The reservoir is prone to contamination with nitrites in almost all seasons of the year from 0.05 to 0.20 mg/dm3 (December, 2016). In the lower reaches of the Ural River, the content of readily oxidizable organic compounds ranges from 3.2 mg/dm3 (winter) to 7.36 mg/dm3 (autumn). The content of boron exceeds the maximum permissible concentration 1-3 times. Environmental monitoring conducted in different periods of the year showed a constant source of pollution flow into the reservoir, which was increased in the flood period. Concentrations of nitrite, boron and petroleum products in the Ural River exceed their permitted values at the point in the end of Uralsk city. The results of the research confirm that the source of the contamination of Ural River is its confluent Ilek River originating from Aktobe Oblast.

AbstractThe aim of the study was to evaluate the impact of potential pollution sources, mainly from the upstream anthropogenic sources and port-related activities. The in-vestigated area covered a wide range of anthropogenic im-pacts (e.g., industrial wastes, storm water runoff, acciden-tal oil spills, intentional discharges and shipping activities). The quality of water and Sediments was assessed us-ing Standard methods, as physical-chemical parameters, chemistry and biology (microbiology, ecotoxicology) aim-ing to figure the level of pollution and the effect of port-related activities. Seawater quality results agreed generally with environmental Standards. Though, in some samples the concentrations of sulphates (mg/1) and heavy metals (μg/1), as B, As and Se exceeded the recommended lim-its, without posing a serious environmental concern. Most of the surface sediment samples contain critical levels of hydrocarbons (C>12), (mg/kg), polycyclic aromatic hydrocarbons (ng/g) and polychlorobiphenyls (ng/g). For some heavy metals (mg/kg), exchangeable concentrations were found to be very close or above the regulations. The signifi-cance of this study is incontestable taking into account the lack of previous relevant historical data of this area. In this sense, it was possible to indicate, in general, good environmental conditions, despite the industrial and concentrated local port-related activities in the investigated area.
