摘要
采集贵阳市老城区夏季5个典型监测点(太慈桥、贵州师范大学、大西门、省政府及省植物园)的样品进行PM2.5、PM10质量浓度分析。同时对PM2.5中PAHs的质量浓度进行分析。结果表明:贵阳市夏季PM2.5和PM10浓度排序均为太慈桥>省政府>大西门>贵州师范大学>省植物园,且PM2.5和PM10之间有良好的相关性,PM10=0.931 3 PM2.5+0.019 4,R2=0.996 7,PM2.5污染较重。此外,5个监测点总PAHs和苯并(a)芘的分析结果均为太慈桥>省政府>大西门>贵州师范大学>省植物园,苯并(a)芘浓度均未超标。
The mass concentration of PM2,5 and PM10 in Taici Bridge, Guizhou Normal University, Daximen, The provincial government and the provincial Botanical Garden in Guiyang were analyzed, and the mass concentrations of PAHs in PM2.5were also analyzed, the resuhs shows：The concentration of PM2.5 and PM10 of Guiyang in summer is Taici Bridge 〉 The provincial government 〉 Daximen 〉 Guizhou Normal University 〉 the provincial Botanical Garden, and there is a good correlation between PM2.5 and PM10 ,the equation is PM10 =0. 931 3 PM2.5 ＋0. 019 4, R^2 =0. 996 7, and the pollution of PM2.5 is serious. The mass concentration of PAHs and Benzo （a） pyrene is that Taici Bridge 〉 The provincial government 〉 Daximen 〉 Guizhou Normal University 〉 the provincial Botanical Garden while the mass concentration of Benzo （a） pyrene in 5 monitoring sites were not excessive.
