摘要
以黔南地区10座县城为例,10座县城大气化学成份中主要气态污染物为SO2和NO2,通过2004年和2013年两个年度里各县城大气SO2和NO2浓度的对比,结果表明各县城的大气SO2浓度大幅度下降,而多数县城NO2浓度则明显上升,这主要与区域能源利用方式的变化相关。
Taking the ten county towns in Qiannan as an example,the main gaseous pollutants in at-mosphere chemical constituents are SO2 and NO2 .By comparing the concentrations of SO2 and NO2 for the same seasons of 2004 and 201 3,our results showed that the concentrations of SO2 had descended by a large margin and the concentrations of NO2 had ascended obviously,this change was mainly related to the energy u-tilization patterns.
