摘要
利用单颗粒气溶胶质谱仪,分析了襄阳市环境空气中的整体细颗粒物的化学组分。通过对2019年3月21日出现的沙尘污染过程的在线颗粒物化学成分和来源解析,初步探讨了这次污染过程的主要来源和成因。研究表明:此次污染过程中扬尘源明显升高,主要是受北方沙尘传输的影响。
In this study,the chemical composition of fine particles in the ambient air of Xiangyang City was analyzed by a single particle aerosol spectrometer.Based on the analysis of the chemical composition and source apportionment of the real-time particulate matter in the sand dust pollution process on March 21,2019,the main sources and causes of this sand dust pollution process were preliminarily discussed.The result shows that the dust source increased remarkably during the sand dust pollution process,which was mainly influenced by the dust transportation from the north region.
