Investigation and analysis on air quality around a power plant in Xi'an

Abstract

The effect of power plant on air quality is a focused issue. The intention of this paper is to survey the air quality around a power plant in Xi'an. The concentration of pollutants in non-heating season and heating season has been tested, and the concentration of pollutants in different time of a day has been tested. In non-heating season, the concentrations of sulfur dioxide and nitrogen oxide at each test point meet the national standard of daily average concentration. The distance of maximum concentration of pollutants is 2 km to the leeward. The concentration of particular matter at six test points exceeded the national standard of daily average concentration. In heating season, the concentrations of sulfur dioxide, nitrogen oxide, and particulate matter at each test point meet the national standard of daily average concentration. Compare the results of non-heating season and heating season, the concentrations of particular matter are higher in non-heating season. The road dust and the sand soil dust have an important effect on the concentrations of particular matter. © Springer-Verlag Berlin Heidelberg 2014.
