珠三角地区大气重金属的现状分析

近年来,我国的重金属污染事件频繁发生,大气重金属污染已经引起广泛的关注。统计了近十年来文献中珠三角地区大气PM2.5重金属(As,Cd,Cr,Pb,V,Zn,Cu,Mn)的浓度和重金属的空气污染特征,并运用US EPA的环境健康风险评价模型对环境空气中的重金属对人群的潜在的健康风险进行评价,以期为深入开展该地区大气重金属污染特征研究和污染防治提供参考。

In recent years, the atmospheric pollution of heavy metals has attracted widespread attention, because of the heavy pollution events occur frequently. This paper summarizes the concentrations of atmospheric heavy metal （As, Cd, Cr, Pb, V, Zn, Cu, Mn）in the PM2.5 in the Pearl River Delta, the characteristics of air pollution by heavy metals in the Pearl River Delta, and evaluated the potential health risk of heavy metals by the EPA US environmental health risk assessment model. In order to provide the reference that further studying the characteristics of pollution and the pollution prevention and control on the heavy metal of atmosphere in the Pearl River Delta.
