摘要：

介绍雾霾及PM2.5的基本知识,从化学角度讨论PM2.5的来源、成分、形成和危害;阐述发展PM2.5分析新方法对于掌握其危害,研究其生理影响和找到其源头的重要意义。清洁能源的高效利用,排放物的后处理以及“碳交易”等有希望成为解决雾霾及PM2.5问题的突破口。

关键词: 雾霾, PM2.5, 光化学烟雾, 挥发性有机化合物(VOCs), 颗粒物

Abstract:

The source, composition, formation and hazard of haze and PM2.5 were introduced. The development of new methodology for the analysis of PM2.5 is important for the understanding of the hazards, the study of the biologic effects, and the finding of the source of haze and PM2.5. The efficient utilization of clean energy, the post-processing of effluents, and "carbon trading" may become the breakthrough points to solve haze and PM2.5 related issues.

Key words: Haze, PM2.5, Photochemical smog, Volatile organic compounds(VOCs), Particles
