Environmental Assessment of Atmospheric Air Quality in Urban Landscapes
摘要
The problem of the impact of charcoal production on the natural environment is quite urgent, since its use is one of the most common forms of energy production in many countries of the world. Definition and environmental assessment of the effect of emissions from charcoal production enterprises on the state of atmospheric air within urban landscapes. Chemical ecological analysis, instrumental analysis, calculations, generalization, systematization, comparative analytical, descriptive, cartographic. Environmental assessment of the effect of charcoal production emissions on the state of air quality within urban landscapes was performed. It was established that the source of atmospheric pollution at the investigated enterprise is 4 pyrolysis furnaces for charcoal production. The operation of the equipment releases into the atmospheric air nitrogen oxides, carbon monoxide, undifferentiated suspended solid particles (smoke), ethane, methanol, acetic acid, acetone, greenhouse gases (methane, carbon dioxide, dinitrogen oxide, NMVOC). In total, 324.7 t/year of pollutants are released into the atmosphere, of which 4.21 t/year are harmful. The effect of pollutant emissions on the state of air pollution within urban landscapes was assessed from the results of calculations of the dispersion of pollutants in atmospheric air and that data obtained from instrumental measurement methods. Taking into account the existing background pollution, the concentration of pollutants in the atmospheric air at the border of the regulatory sanitary protection zone does not exceed the hygienic standards. The quality of atmospheric air is within maximum permissible concentration of pollutants whereby negative impact on human health and the state of the environment is absent.
