摘要

探讨了2002年春季内蒙古多伦县总悬浮颗粒物（TSP）和细颗粒物（PM2.5）的分布特征以及颗粒物浓度与气候的关系。并用仪器中子活化分析法（INAA）测定了TSP的元素成分

利用多种多元统计方法探讨了多伦春季TSP的可能来源。结果表明

多伦春季TSP和PM2.5污染较严重;TSP浓度主要受风速影响

而PM2.5浓度随气候变化其行为较复杂;TSP主要来自于地壳源

其中Cl与其它元素的相关性很小

可能主要来源于燃煤

而Br、Zn除了地壳来源外还有燃煤和废物焚烧的贡献。

Abstract

Duolun

a small town of the Inner Mongolia

was selected as a sampling site to collect the local sand

TSP and PM2.5 during dust storm period in the spring of 2002. The elemental compositions of TSPs were measured by instrumental neutron activation analysis (INAA). The relationship between aerosols mass concentrations and meteorological conditions was studied

and the sources of TSP were also investigated by the correlation analysis

principle factor analysis and cluster analysis. The results showed that most elements in the Duolun’s TSPs came from the crust

whereas Br and Zn were from both anthropogenic activity and the crust. Since Cl exhibited an exceptional correlation with other elements

its existence could be attributed to the coal combustion.
