北京市2.5μm小颗粒大气气溶胶特征及来源
The Characteristics of 2.5 μm Aerosol Measurements in Beijing
【摘要】 对北京市采暖期和非采暖期 2 .5 μm小颗粒进行了初步研究 ,采用多元素同时测定及化学质量平衡法对其进行解析 .这研究将对北京市治理环境污染提供科学依据和政策建议
【Abstract】 m aerosol samples were collected in winter / nonwinter and determined by means of Inductively Coupled Plasma(ICP). Meanwhile, the source apportionment of 2.5 μm aerosol was identified using Chemical Mass Balance (CMB) model. Results showed that Traffic emissions, Resuspended soil dust and Combusting coal soot are the three largest main sources of atmospheric pollution in Beijing.
