摘要
羰基化合物是大气中很重要的一类中间化合物,对于大气中臭氧及二次有机气溶胶生成有重要的促进作用。同时,羰基化合物同时存在于气态及颗粒态中,其气粒分配行为对区域大气复合污染乃至全球气候变化等方面都具有重要意义。文章对羰基化合物的分析方法进行了文献总结,并归纳了羰基化合物的实验研究和外场观测。针对目前已有研究存在的不足,进一步提出了研究展望。
Carbonyl compounds are the important class of intermediate compounds in ambient atmosphere which play an important role in the formation of ozone and secondary organic aerosols. Carbonyl compounds exist in both gaseous and particulate phase. The gas-particle partitioning of carbonyl compounds was of great significance to regional air pollution and even global climate change. This review summarizes the the analytical methods and the experimental research and field observation of carbonyl compounds. In this review, we discuss findings presented in recent studies on the partition mechanism, the partition process of ambient atmosphere, existing knowledge gaps, and recommendations to help address these gaps for future research.
