大气中重金属污染现状及来源研究

总结了近年来的研究成果,通过文献调研对中国大气中重金属污染现状、大气中重金属来源和重金属在环境中的迁移转化途径进行综述,提出为缓解重金属污染的高发态势,保护人群健康,应建立完善的环境污染防治体系,强化大气污染源颗粒物控制来减少重金属在大气环境中的暴露浓度,切断重金属在环境中的污染途径以减少大气传输和沉降,降低由大气-土壤-动植物-人体的重金属暴露健康风险.

Current Status and Sources of Heavy Metal in Atmosphere

The paper summarizes the research results in recent years through literature research on the status of heavy metal pollution in the atmosphere, the source of heavy metals in the atmosphere, migration and transformation of heavy metals in the environment.It proposed to alleviate the high incidence of heavy metal pollution, establish a sound environmental pollution control system, strengthen the control of atmospheric pollution sources to reduce the exposure concentration of heavy metals in the atmospheric environment, cut off the heavy metal pollution in the environment to reduce atmospheric transmission and sedimentation, reduce the atmosphere-soil-animals and plants-the human body heavy metal exposure to health risks.
