我国部分城市土壤和降尘重金属污染现状与研究展望（英文）

Current Situation of Heavy Metal Pollution in Soil and Dustfall in Some Cities of China

人类活动导致我国城市土壤、降尘均存在不同程度的重金属污染,但各城市之间重金属危害类型与污染程度存在差异。依托收集到的城市土壤、降尘重金属污染案例资料,在调研相关资料基础上,阐述我国23个城市土壤、降尘重金属污染现状,并针对目前重金属污染研究存在的问题提出建议,旨在为后期政府决策和相关科研提供参考。

Because of human activities, urban dustfall and soil in China have been polluted by heavy metals in different degrees. However, the type and pollution degree of heavy metal hazard are different among cities. Based on data about the heavy metal pollution of urban soil and dustfall as well as related information inves- tigated, the present situation of heavy metal pollution in soil and dustfall in 23 regions of China were summarized, and some suggestions were put forward accord- ing to the existing problems of research on heavy metal pollution, aiming to provide reference for government decision-making and related research in future.
