大气颗粒物中重金属分布特征和来源的研究进展

Advances in the Study on Distribution Characteristics and Sources of Heavy Metals in Atmospheric Particulates

近年来,大气颗粒物引起的环境空气污染受到广泛的关注。颗粒物的研究内容主要集中在不同时间、空间和不同粒径颗粒物浓度的测定、成分分析和健康效应等方面。该文针对颗粒物中的重金属成分,从其含量水平、分布特征、赋存状态和来源分析上进行综述,总结目前对颗粒物中重金属的研究成果,并展望该领域研究方向。

In recent years, more and more attention was paid to environmental air pollution caused by atmospheric particulate matters. The studies on atmospheric paniculate matter concerned mainly in PM10 and PM2.5, uhrafine particulate matter （PM0.1） have gradually aroused the attention of many researchers. The main research of atmospheric particulate matter focused on the detection concentrations at different time, different space, and different diameter, particle composition analysis, human health effects and the other aspects. In the present paper, the levels of heavy metals, characteristics of distribution, existing form and the sources identification of heavy metals in atmospheric paniculate matter were reviewed, the current research results of heavy metals in paniculate matter were summarized and the future prospects of research in this field were discussed also.
