Spatial distribution of pollutants in the area of the former CHP plant

Abstract

Abstract. The quality of atmospheric air and level of its pollution are now one of the most important issues connected with life on Earth. The frequent nuisance and exceedance of pollution standards often described in the media are generated by both low emission sources and mobile sources. Also local organized energy emission sources such as local boiler houses or CHP plants have impact on air pollution. At the same time it is important to remember that the role of local power stations in shaping air pollution immission fields depends on the height of emitters and functioning of waste gas treatment installations. Analysis of air pollution distribution was carried out in 2 series/dates, i.e. 2 and 10 weeks after closure of the CHP plant. In the analysis as a reference point the largest intersection of streets located in the immediate vicinity of the plant was selected, from which virtual circles were drawn every 50 meters, where 31 measuring points were located. As a result, the impact of carbon dioxide, hydrogen sulfide and ammonia levels could be observed and analyzed, depending on the distance from the street intersection.

Selected air pollutants in urban and rural areas, under the influence of power plants

“…In agricultural areas, characterized by low density of buildings, low population density and large vegetation area, there is a lower concentration of pollutants from vehicle traffic and individual heating systems, which means that the quality of air in these areas is considered to be cleaner and therefore "better" [12,16]. However, the emission from point sources of power stations may have a major impact on the concentration of air pollutants in these areas [17][18].…”
