城市大气颗粒物中锑污染研究进展

Research progress of antimony pollution in urban atmospheric particulate matter

随着工业化和城市化发展,高强度人类活动及锑化合物的广泛使用使城市大气环境中锑污染日趋严重。进入大气中的锑能长时间驻留并随大气环流进行长距离迁移造成跨区域污染。鉴于锑对人体的潜在毒性及致癌性,城市大气环境锑污染引起学术界和国家相关部门的高度重视,然而目前国内关于大气环境中锑的研究仍处于初期阶段。对城市大气颗粒物中锑的来源、污染特征、源解析等方面进行综述,在此基础上对大气环境中锑污染来源、迁移转化过程研究中的锑同位素应用前景进行展望,为进一步开展城市大气颗粒物锑污染研究、防治和环境管理提供参考。

The pollution of antimony(Sb)in urban atmosphere is becoming more and more acute due to the development of industrialization and urbanization,as well as frequently human activities and the common usage of Sb.The Sb entered into the atmosphere can stay for a long time and migrate over long distances with atmospheric circulation,and causing cross-regional pollution.It has aroused government and academics’highly attention for the potential toxicity,carcinogenicity and long-distance migration,while the current study about the Sb in atmosphere is still in the primary stage.This paper reviewed the source,pollution feature and source appointment of Sb in atmospheric particulates,based on which,the application prospect of antimony isotope in the study of the source,migration and transformation of Sb pollution in atmosphere were looked forward.These conclusions could supply some references for the further study of Sb pollution in urban atmospheric particulates,and give some advises for Sb pollution prevent and control in atmosphere and its environment management.
