Particle Size Distribution and Source Analysis of Inorganic Elements in Atmospheric Aerosol in Xinglong Base Station
摘要
Abstract
The concentrations of 25 elements such as Ca,Na,Mg,Fe,Al and K were determined by ICP-MS,and the concentration characteristics,particle size distribution and source of these elements were discussed.The results show that Ca,Na,Mg,Fe,Al and K in inorganic elements in the aerated aerosol are 96％ of the total concentration of the measured elements,and all the elements show a high concentration level in the autumn.The particle size distribution shows that the 25 kinds of elements detected in this study show almost double-mode distribution,peaks apeared in the 4.7 ～ 5.8 μm grain size and small peak in the 0.43 ～ 0.65 μm particle size.The results of enrichment factor analysis show that Xinglong is mainly affected by crustal source and combustion source.关键词
