摘要
利用2005—2007年乌海市区大气中SO2、NO2、PM10浓度的实测数据,分析了乌海市大气污染物的时间分布特征,分析结果表明:乌海市首要污染物是PM10,其次是SO2;从2005—2007年日平均值看:SO2、PM10呈下降趋势,NO2略呈上升趋势。SO2、NO2、PM10的浓度都有明显的季节变化。
Using of the observation data of concentration of SO2,NO2,PM10 in atmosphere from 2005 to 2007 years in Wuhai city in this article, the temporal distribution characteristics of atmospheric pollutant were analyzed.The results showed that the main pollutant is PM10, SO2 is secondary, from 2005 to 2007years, daily mean concentration of SO2 and PM10 was dicline, NO2 was opposite, the concentration of SO2.NO2 and PM10 show seasonal character obviously.
