我国大气可吸入颗粒物中重金属污染特征研究进展

Research Progress on the Pollution Characteristics of Heavy Metals in Atmosphere Particulate Matter in China

大气污染带来了严重的环境问题,PM_(2.5)及其载带的金属污染受到重视,其中Cr、Cd、Pb、Ni等典型重金属元素污染的危害更为重要。本文从常用的检测方法ICP-AES、ICP-MS、AFS、AAS、电化学分析,和可吸入颗粒物中重金属的来源,重金属形态与生物活性、分布特征等方面进行了综述,从而分析了可吸入颗粒物中重金属污染特征研究进展,并针对以上内容展望了未来研究我国大气可吸入颗粒物中重金属来源、组成追踪分析、生物有效性评价等工作的必要性。

Atmospheric pollution causes environmental problem. The pollution with Cr, Cd, Pb, Ni were more serious. This paper reviewed some detection methods including ICP-AES, ICP-MS, AFS, AAS, electrochemical analysis, the sources of heavy metals, speciation and bioactivity and distribution characteristics and analyzed its research progress. It prospected the necessity of the sources of heavy metals, the composition of tracing analysis and bioavailability assessment in inhalable particles in China.
