  • 摘要: 利用便携式气溶胶采样器对沈阳市崇山中路辽宁大学附近PM2.5的质量浓度进行了监测分析,研究了沈阳市交通干道附近PM2.5的污染特征及变化规律,同时记录了采样期间的机动车流量数据。结果表明:受季节性污染源及气象因素影响,沈阳市交通干道附近PM2.5质量浓度采暖季明显高于风沙季和夏秋季。监测期间,PM2.5质量浓度的逐时变化曲线呈现双峰特征,8:00~10:00时和21:00~22:00时浓度值高,期间浓度值低。PM2.5质量浓度与交通流量变化趋势基本一致,均呈现双峰特征。
    Abstract: In this paper, portable aerosol samplers were used to monitor and analyze the concentration of fine particulates near Liaoning University located in Chongshanzhong Road, Shenyang City. The pollution characteristics and variation laws of fine particulates near the traffic roads were studied. Meanwhile, the flux of vehicles through the crossing during sampling was also investigated. The results showed that affected by seasonal pollution sources and meteorological factors, concentration of PM2.5 near the traffic roads in heating season was significantly higher than that in windy season, summer and autumn. During the monitoring period, variation of PM2.5 concentration showed a bimodal feature higher from 8:00 to 10:00 and from 21:00 to 22:00 but lower at the rest of the day. Variation trend of PM2.5 concentration basically complied with that of the traffic flux, both showing a bimodal pattern.
