Environmental safety is one of the most important international and national tasks when using chemicals such as mercury, its compounds and mercury containing waste. Mercury (Hg) is a global pollutant. Constant anthropogenic mercury emissions and its presence in food chains affects human and ecosystem health and cause serious concerns. When released into the atmosphere with various emissions, mercury is deposited on the ground or water surface. Due to the global transport of mercury in the environment, its release is possible near sources of pollution, as well as at a remote distance. Keywords: mercury–containing wastes, Minamata Convention, immobilization

Purpose Monitoring of acidic impurities in the atmospheric air of residential areas of settlements is one of the areas of ensuring their environmental safety and is officially carried out at 221 stations in the Russian Federation in the study of atmospheric precipitation.Method. In areas where they are minimal, the author proposes an alternative method for assessing environmental pollution based on the preparation of aerosol suspensions. The purpose of this work was to study the acidity index (pH) of aerosol suspensions (washing off aerosols from the leaves of apricot trees (Prunus armeniaca) obtained in the Srednyaya Akhtuba region (Sredneakhtubinsky district of the Volgograd region) in the spring-summer of 2020.Result. The results of the research demonstrated acidic aerosols ( pH = 5.32 + 0.01) in the atmospheric air rp Srednyaya Akhtuba in comparison with the conditionally clean zone (SNT "Oroshenets", "Shelf"), (pH = 6.39 + 0.02) The data indicate environmental pollution and on environmental risks for the population.Conclusion. Acidic impurities in the atmosphere of the middle Akhtuba region in comparison with the conditionally clean zone (SNT "Oroshenets", "Shelf"), which indicates environmental risks for the population. sources of pollution in residential areas of the settlement of Srednyaya Akhtuba and to develop environmental measures to protect the population from acidic impurities contained in aerosols, which requires further study of the territory.

ABSTRACT The rupture of a pipeline transporting hydrocarbons at high temperature caused the spill of 1,300 m3 of fuel oil near the Guanabara Bay shoreline, on January 18, 2000. Immediately after the accident, an emergency effort was undertaken to obtain satellite images in order to monitor the spill's location and movement. One Landsat-5/TM (Thematic Mapper) and 15 Radarsat-1 images were acquired This paper describes the results obtained with the interpretation of the first three images acquired after the spill. The low frequency of acquisition and the prevailing cloud cover limited the use of visible and infrared spaceborne sensors. Image processing techniques were applied to highlight oil-covered areas on the water surface. Ambiguities in the oil detection were resolved with the aid of ancillary information such as location of knows sources of pollution; aerial inspection information and GPS controlled aerial photos taken from helicopters. The RADARSAT-1 images show clearly the area affected by the spill accident allowing the differentiation of oil-free water areas, fluvial discharge or effluents areas, and oil-covered water areas. One limitation to oil detection using the Landsat-5/TM image was the presence of clouds and haze near the spilled area. In order to improve the visual discrimination of patterns on the water surface related to oil, many RGB combinations of the seven TM bands were evaluated. A supervised classification procedure was applied resulting in the following classes: oil-free water, fluvial discharge, bay areas affected by haze and oil-covered water. The GIS integration of the classification results with ancillary information, such as location of knows sources of pollution; aerial inspection information and GPS controlled aerial photos acquired simultaneously with image acquisition, allowed the final selection of oil-covered areas. The results obtained helped PETROBRAS to optimize the emergency response procedures and subsequent cleaning efforts.

Abstract Mercury is a global pollutant that can accumulate in organisms and endanger human health. This paper studied the soil, plants and animals in the light beach, Suaeda wing wetland, reed wetland and rice field in the Liaohe Estuary in 2018 and 2019, and determined the stable carbon and nitrogen isotopes of animals and plants to construct the food chain. The results show that from 2018 to 2019, the accumulation of mercury in the soil of the light beach, Suaeda winged wetland and reed wetland of the Liaohe Estuary continued to increase, but the accumulation of mercury in paddy soil showed a decreasing trend; the mercury content in plant samples also showed a certain degree There is a positive correlation between the accumulation of mercury in the food chain and the construction of trophic levels in the food chain. Mercury can carry out efficient biomagnification and bioaccumulation through the food chain.

Rational use of natural resources is one of the most acute problems not only in Belarus, but throughout the world. The development of industry, transport and the use of high-intensive technologies in agricultural sector result in the increase of air, land and water pollution. At the same time, wastewater is one of the sources of pollution, despite the fact that much attention is paid to their treatment and neutralization. Currently, various technologies are used for the disposal and treatment of livestock waste. One of them is the utilization of livestock waste for fertilizer irrigation of crops. For practical implementation of fertilizer irrigation, specialized reclamation systems have been built, a technology at the complexes that is based on the principle of full water circulation. Typically, such systems include a network of underground pipelines and irrigation equipment for irrigation, various purpose hydraulic structures, a fence and a drainage network for collecting contaminated surface and drainage water, which accumulate and reuse it for irrigation. When analyzing the operation of such water circulation system, at first glance it seems that the spread of pollution outside the irrigated territory is excluded. However, practical experience shows that complete cleaning and environmental safety, even on advanced systems, is not provided. Therefore, the performance of individual elements of the water reclamation system for fertilizer irrigation requires in-depth study and improvement.

Excessive and unbalanced use of the pesticides that is necessary to protect agrophytocenoses against pests leads to environmental pollution. Harmful pesticides tend to enter the natural cycles of substances. Therefore, they are quick to disappear or be destructed by biological agents. There are also “nondestructive” pesticides, which do not enter the natural cycles; neither they are accumulated in food chains and in biotopes. These substances have become an object of research in the fi eld of environmental safety.

Ensuring environmentally safe conditions for the use and development of coastal areas, which usually have a high level of urbanization, is an important engineering and socio-economic task, since it requires tak-ing into account environmental factors of natural and man-made environments when optimizing planning solutions for development and organization of activities. The work is devoted to the study and identification of areas of environmental risk in the current resort and recreational, residential and industrial areas, com-plex environmental conditions and prospects for the development of coastal areas of the Crimea (for exam-ple, recreational complexes of the southern coast of Crimea). When conducting research of problem areas, the structure of the drainage system, with an emphasis on stormwater, areas of municipal solid waste (MSW) and the impact of highways, has been studied in detail. Conducted researches allowed to establish for all in-vestigated water objects changes of water quality due to the flow of non-canalized domestic sewage, the storm sewers, sewage waters of individual small private enterprises, the unorganized surface drain during rains, a high recreational load on separate beaches. The highest level of pollution, including microbiological, coastal marine waters are observed when they are to several sources of pollution at the same time. Considered possi-ble measures to reduce or overcome negative processes in the environment. In order to improve the ecologi-cal condition and recreational value of coastal beaches, it is necessary to redistribute the flow of residents throughout the coastal zone, to solve the problems of water supply, sanitation of territories for the placement of solid waste and other waste, and to take preventive and technical measures for the protection of coastal recreational zones. The research results can be used in the development of projects for the reconstruction of the territory of coastal settlements of the southern coast of Crimea while ensuring environmental safety.
