环境因素影响二次有机气溶胶生成的研究进展

二次有机气溶胶 (SOA) 是大气颗粒物的重要组成部分, 对能见度、气候变化和人体健康有着重要的影响, 因 此备受广泛关注。近年来我国空气质量虽得到明显改善, 但复合污染现象仍然十分严峻。为更好地评估 SOA 对大气 复合污染的影响, 获得准确的参数化数据, 为区域污染防控提供科学依据, 需要对 SOA 进行更深入的研究。鉴于此, 总 结了近年来有关环境因素对 SOA 生成影响的研究, 指出多重环境因素的复合作用对 SOA 的生成具有重要的影响。并 结合目前研究现状, 对未来研究前景进行了展望。

Research process of influence of environmental factors on secondary organic aerosol formation

Secondary organic aerosol (SOA) accounts for a significant proportion of atmospheric particles, which has attracted wide attention because of its impact on visibility, climate change and human health. Although air quality in China has been significantly improved in recent years, atmospheric complex pollution is still serious. In order to better evaluate the influence of SOA on atmospheric complex pollution, obtain accurate parametric data and provide scientific basis for regional pollution prevention and control, comprehensive characterization of SOA is needed. In view of this, the research of environmental effects on SOA formation in recent years has been summarized, and that the synergetic effect of multi-environmental factors has an important influence on SOA formation has been demonstrated. In addition, the future prospect has also been suggested based on the present research.
