摘要
本文通过对国内外PM2.5监测网络布局现状的分析和比较,认为我国"十二五"规划的PM2.5监测网络在点位数目和网络布局上基本能够反映我国PM2.5污染状况。为进一步反映PM2.5的污染特征和来源,今后应逐步增加污染监控点位、道路交通点位的设置,并在质量浓度监测的基础上,逐步开展PM2.5主要组分监测。在监测方法选择上,β射线法联用动态加热系统(DHS)PM2.5自动监测仪器和振荡天平法联用膜动态测量系统(FDMS)PM2.5自动监测仪器均能够满足监测工作的需要,综合考虑两种类型仪器的性能指标和运行成本,β射线法联用动态加热系统(DHS)PM2.5自动监测仪器操作相对简单,运行维护成本相对较低,更适合在我国环境空气监测网络内推广和普及。
Based onanalysis and comparisonof the fine particle monitoring networks between China and abroad , the paper points that the existing network proposed in the air monitoring strategy during the 12th five year is available for reflecting the status of PM2.5 pollution. In order to research the characteristic and the source of PM2.5 , should considerate setting up some industrial stations and traffic stations, and monitoring both mass concentration and major chemical composition in the future. In the matter of monitoring technique, bothbeta attenuation monitor incorporates a dynamic heating system and tapered element oscillating microbalance monitor incorporates a filter dynamic measurement system can meet the demand, after estimating the performance and running cost of each monitor, we could come to the conclusion that the beta attenuation monitor is more convenient to operate and has lower cost, and is more suitable to be used in the PM2.5 monitoring network in China.
