Modern Increasing Environmental Problems of Atmosphere Pollution Leading to Significant Increase in Planet Population Deaths and Economic Damage to Global Economy

The article analyzes two existing social, technical and economic problems which the world community shall focus on and pay special attention to.

METHODS FOR ASSESSING THE CITY ATMOSPHERE POLLUTION ACCORDING TO MONITORING DATA

The problem of assessing the city's atmospheric pollution based on monitoring data at stationary observation posts is considered. The results of the research carried out on the example of Iskitim city in the Novosibirsk region are discussed. The analysis of the relationship between the frequency of impurity emissions from dominant sources and the measured concentrations at the stationary observation point of the city for winter periods of time is carried out. The influence of the frequency of winds of different directions on the formation of the level of atmospheric pollution at the control post has been investigated. Taking into account the relative position of the observation point and the main highway of the city, a noticeable contribution of southwestern winds to the increase in benzo (a) pyrene concentrations is shown. The regularities of the formation of atmospheric pollution in calm conditions have been studied. A statistical relationship has been established between the number of calm recorded during the month at the Iskitim meteorological station and the values of benzo(a)pyrene concentrations.

THE PECULIARITIES AND IMPACTS OF AIRPORTS: THE CASE FOR MALTA INTERNATIONAL AIRPORT

The small-to-medium sized Malta International Airport (MIA) is the only airport in Malta, especially in terms of its footprint, and is considered one of the world’s most scenic landings, according to a 2016 poll. The annual passenger turnover is approximately 16 times the country’s population. MIA’s unique features include its proximity to the urban conservation area of Luqa, as well as that town’s other residential and business facilities, and also to the southern coast of Malta and the unique ecological habitats it supports. Its impacts range from noise to atmosphere pollution and, potentially, pollution of the coastal waters, in the eventuality of an air traffic accident. On the basis of the national strategic vision that Malta evolves into an expanding hub in the centre of the Mediterranean, significant investment is earmarked for MIA, including initiatives impacting security, the environment and energy.

Man-made pollution of the environment with coal dust as a result of operation and closure of coal mines

The technological processes of coal mining, enrichment and use, in particular coal combusting is accompanied by formation and release of significant amounts of dust and gases. Atmospheric air protection is one of the most urgent problems of the nowadays technological society, as scientific and technological progress and expansion of production is associated with an increase in negative anthropogenic impacts on the atmosphere. The paper presents a new solution to the current scientific problem of reducing carbon-containing dust content based on the disclosure of the laws of the aerodynamic interaction of dust and water flows in gravitational and electrostatic fields. The authors show in this study the causes of atmosphere pollution with coal-containing dust; main issues of atmospheric air protection at enterprises located in the controlled territory of Ukraine. The data of the first quarter of the 2020 year are presented in the research. The biggest part of the facilities that pollute the atmospheric air are focused in Donetsk and Lugansk regions. It is estimated that the air environment of the underground mine surface complex is filled with exhaust ventilation air of approximately 200.000 m3 per minute with a dust concentration of approximately (5-7) mg / m3, which is equal to 1.5 tons of dust per a day. It is here that the possibility of transporting pollutants over long distances is most often realized. Coarse dust discharged through the ventilation systems of mines is intensively deposited in the sanitary protection zones of mines. Fine dust is carried by the wind outside them, polluting the environment on the distance of up to 3500 m from the coal mine. Emissions of carbon dust into the atmosphere are almost always a major part of transboundary environmental pollution. Mine waste also poses an environmental threat. Technologies of reduction air pollution at the source of carbon-containing dust formation should be used in all new industries of economy. The results obtained reveal the mechanism of interaction of the sprayed liquid with coal dust and can be used in the development of new effective means of controlling the carbon-containing dust. The principles and practices of sustainable development, coupled with local research, will help to contain or eliminate health and environmental risks resulting from air pollution by carbon-containing dust.

ATMOGEOCHEMICAL INDICATORS - INDICATORS OF FOREST - STEPPE LANDSCAPES DEGRADATION

Anthropogenic development of forest-steppe landscapes has a long-term character. For the landscape-geochemical systems of the forest-steppe, under the conditions of the prevalence of vertically directed geochemical flows, the main limiting factor of functioning is the presence of a sufficient amount of atmospheric precipitation. Geochemical monitoring is carried out on the territory of the Kursk Biosphere Station, one of the purpose of which is to study the atmogeochemical component of forest-steppe landscapes. It is shown that atmogeochemical indicators - dustiness of the atmosphere, pollution of atmospheric precipitation, snow cover - can act as indicators of geochemical degradation of landscapes. For the assessment of atmospheric pollution of the natural landscape and definition of air routes of migration of the elements of a permanent atmogeochemical monitoring is required.
