摘要
为初步调查贵阳市春季空气中颗粒物PM2.5、PM10、TSP的污染状况,2012年4月～5月在贵阳市某城区-典型混合区采样20d。结果表明,TSP未超标,PM2.5、PM10质量浓度范围分别为0.042～0.130mg/m3和0.056～0.180mg/m3,其超标率分别为50%,15%。且PM2.5与PM10之间存在显著的相关性,相关方程为PM10=1.3482PM2.5-0.0028,其中对人体健康危害更大的PM2.5平均占到PM10的77.27%,说明该区的细颗粒物污染严重。
Investigation conducted into pollution condition about particulate matters, TSP, PM10 and PM2.5 in Guiyang city. Samples collected from 25 April 2012 to May 15, total 20 days, in some mixed functional city areas. Resuits showed TSP complied with national ambient pollutants standard while PM10 and PM2. 5 failed to meet the standard with concentration range from 0. 042-0. 130 mg / m^3 for PM2.5 and 0. 056-0. 180 mg / m^3 for PM10, which exceeded the limit for 50% and 15 % respectively. Moreover, PM2.5and PM10 have significant correlation with possible correlation equation, PM10 = 1. 3482PM2.5 -0. 0028. Specifically, the PM2.5,which proved to have more adverse impacts on human health , accounted for 77. 27% for PM10. The results indicate fine particulate matters pollution present serious problems in studied areas.
