大气气溶胶中痕量金属元素的研究进展

综述了近年来国内外学者对大气气溶胶中痕量金属元素的研究进展,介绍了痕量金属元素的地球化学行为,以及大气气溶胶中痕量金属的源解析方法、在环境中的循环与污染、生物有效性及对人体的健康效应。建议研发更可靠的分析方法或在线检测仪器,避免采样和样品前处理过程中痕量金属的污染和损失;建立监测网络,形成区域性的大气监测模式,更全面地分析污染来源;与监测超级站建设、空气污染流行病学设计和毒性机制研究相结合,建立更加完善的研究体系。

Research Progress of Trace Metals in Atmospheric Aerosols

In this paper,the research progress of trace metal elements in atmospheric aerosols by domestic and foreign scholars in recent years are reviewed.The geochemical behavior of trace metal elements are introduced,as well as the methods of source apportionment of atmospheric aerosol in trace metals,the recycling and pollution of aerosol trace metals in the environment,the aerosol bioavailability and the effects on human health.It is recommended to develop a more reliable analysis method or online instrument to avoid contamination and loss of concentration in the process of sampling and sample pre treatment; to establish a monitoring network to form a regional atmospheric monitoring model,and a more comprehensive analysis of pollution sources; to combine with the construction of super monitoring station,the epidemiology designing of air pollution and toxicity mechanisms,so as to create a more complete research system.
