摘要
于2015年秋季(1月)、夏季(8月)对贵阳市五个区的大气颗粒物(PM10、PM2.5)进行了监测研究。结果发现,贵阳市大气颗粒物污染很轻,8月和11月PM10、PM2.5的超标率都为0;大气颗粒物PM10和PM2.5浓度季节变化大,11月PM10和PM2.5浓度明显大于8月;2个月的监测数据显示5个区PM10和PM2.5日均值浓度变化趋势基本一致,5个区中南明区的PM10和PM2.5浓度最高,花溪区的PM10和PM2.5浓度最低。PM10中PM2.5比重较大,PM2.5粒径小,对人体健康危害很大。
The airborne particulate matter（ PM10,PM2. 5） of the five distinct of the Guiyang city in the autumn（ November） and summer（ August） of 2015 were monitored in this study. The results showed that airborne particulate matter pollution in Guiyang is very light,and the exceeded the rate of PM10,PM2. 5 in August and November are 0;The concentrations of PM10 and PM2. 5 variate greatly in different seasons. The monitoring data showed that the daily concentration change of PM10 and PM2. 5 is basically the same in the five district,the concentration of PM10 and PM2. 5 in Nanming District was highest,while the concentration of PM10 and PM2. 5 in Huaxi District was lowest. The larger proportion of PM10 is PM2. 5,PM2. 5 small particle size,great harm to human health.
