| Abstract: | The statistical analysis of the monitoring data of NO2, SO2 , PM10 in the urban area of Yiliang County during 2006 -2011 shows that the main pollutant is SO2. As far as the yearly variation of the concentration of the three pollutants is concerned, the concentration of NO2 and SO2 is clearly going down while that of PMI0 is in a slight downward trend. The seasonal variation of their concentration is as follows： SO2 winter 〉 autumn 〉 spring 〉 summer; NO2 and PM10 winter 〉 spring 〉 autumn 〉 summer. The pollution control measures are proposed. |
