摘要
对大气颗粒物理化特性的在线监测不仅直接有利于按照国家环境空气质量新标准实施空气质量实况发布,更是全面掌握细颗粒物污染特性、污染成因、形成机制与制定控制对策的关键性基础工作。文章综述国内外关于大气颗粒物理化特征的典型在线监测技术及颗粒物粒径分级技术,如质量浓度、吸湿性、挥发性和数浓度与化学组成及其粒径分布等监测技术,以及单颗粒理化特性在线监测技术,为颗粒物在线监测、灰霾超级站仪器配置和气溶胶污染及其控制研究提供参考。
Continuous, online measurement of physico-chemical properties of atmospheric aerosols makes it possible to reveal the properties and formation mechanisms of aerosol pollution, relating to the effective countermeasures to control aerosol pollution. In this paper, typical continuous, online physico-chemical property monitoring techniques and particle-size degrading methods of atmospheric aerosols are introduced and reviewed, among others, the monitoring techniques for mass concentration, hygroscopicity, volatility, and number concentration, chemical composition and their size distributions, as well as the techniques for measuring physico-chemical properties of single particles.
