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. |
