摘要
利用单颗粒气溶胶飞行时间质谱仪(SPAMS)对太原市2018年12月大气细颗粒物(PM 2.5)化学成分进行分析,解析了机动车限行时段与非限行时段对PM 2.5来源影响,以期为进一步开展太原市大气PM 2.5治理工作提供科学支持,并为有关部门制定PM 2.5污染排放控制对策提供依据。
The chemical composition of atmospheric fine particulate matter(PM2.5)in Taiyuan city in December 2018 was analyzed by using single particle aerosol time of flight mass spectrometry(spams),and the influence of vehicle traffic restriction period and non traffic restriction period on PM2.5 source was analyzed,so as to provide scientific support for the further development of atmospheric PM2.5 control work in Taiyuan city,and provide suggestions for relevant departments to formulate PM2.5 pollution emission control countermeasures.
