Abstract


The necessity of the control of atmospheric pollution in the zone of anthropogenic influence is determined by preliminary experimental as well as theoretical research which is followed by the calculation of the concentration fields with allowance for meteorological factors characteristic of the reserch region using mathematical models, the study of the zones of influence of industrial complexes. The implementation of such works is relevant in areas of fuel and energy complexes, like the lands of Bovshiv Village in the Galician region of the Ivano-Frankivsk district where Burshtyn Thermal Power Plant of PJSC "DTEK Zakhidenergo is located. On the basis of the anual pollutants gross emmisions the second category of danger with a standard width of the sanitary protective zone of 500 m has been stated for the thermal power plant. According to the calculations of ground concentrations of pollutants at the boundary of the regulatory sanitary protective zone with the employment of the dispersion model, it has been established that its planned standard zone width of 500 m does is not sufficient for the dispersion of the main pollutants emitted by the enterprise. The maximum surface concentrations of pollutants are calculated for the worst for their dispersion under atmospheric meteorological conditions, when the wind speed approaches zero. At such "unfavorable" weather conditions, the scale and dangerous levels of influence of low sources spread within the sanitary protection zone, but for the main high sources they spread outside its boundaries on agricultural lands of settlements. The distances on which the maximum ground concentrations of the emmited substances exceed their maximum permissible values are adjusted for the average annual wind repeat with predominance of Western and North-West winds. The distances on which excess ground concentrations of Suspended Particulate Matter, Nitrogen Oxides and Sulfur Dioxide can be observed are almost doubled. Under such circumstans, the residential areas in the village of Bovshiv is caught into the zone of potential pollution, for which, a comprehensive index of atmospheric air pollution has been calculated and the category of air pollution of "highly polluted" has been established. Therefore, Bovshiv as an area prone to pollution of the Burshtyn TPP is necessary to be included into the regional program of the comprehensive survey of the Burshtyn Industrial District, with the aim of organizing of the permanent environment monitoring.
