摘 要: 民用燃煤排放污染物是我国冬季重污染发生的重要影响源,近年来引起了广泛关注。本研究从民用燃煤污染物排放的角度,系统总结了民用燃煤排放气溶胶粒子及其载带化学组分的粒径分布特征,探讨了在民用燃煤排放烟气稀释过程中冷却凝结形成颗粒物的机制以及烟气排放到大气环境中与其他源排放污染物的协同老化机制,最后分析了单颗粒气溶胶质谱在民用燃煤排放颗粒表征中的应用趋势。本文可为民用燃煤排放气溶胶及其载带化学组分的排放因子、清单构建、有毒有害组分健康效应模拟评价、民用燃煤排放污染物的环境效应研究等提供参考和借鉴。
关 键 词: 大气科学;民用燃煤;综述;气溶胶;粒径分布;老化机制

Abstract: Pollutants emitted from residential coal combustion are important sources for the formation of severe air pollution processes in winter of China, which have drawn widely attention. This paper systematically summarizes the size distribution of aerosol particles and associated chemical components, discusses the formation of particles by condensation and coagulation during dilution process of smoke in residential coal combustion. The collaborative aging mechanism for smoke and other sources is also proposed in recent studies. At last, the application tendency of single particle aerosol mass spectrometer in the emission study of residential coal combustion is analyzed. This paper will provide useful information for establishing emission factors, updating emission inventory, assessing the human health effects of toxic and harmful components and studying environmental effect of pollutants emitted from residential coal combustion.
