摘要
道路沉积物是来源和物质组成都很复杂的重要的环境介质之一,介绍国内外不同城市道路沉积物中重金属污染的研究现状,综述路面沉积物中重金属污染的主要种类和含量,比较沉积物中重金属赋存状态的研究方法,对沉积物中重金属的生物有效性进行分析探讨,探析沉积物中重金属污染的影响因素及其迁移转化过程,对沉积物中重金属的来源进行了判析,在此基础上提出控制道路沉积物重金属污染措施的建议,并指出沉积物重金属污染研究需要解决的问题及其发展方向。
Road surface sediment is one of the main environmental medium with complicated source and composition.The current research status of heavy metal pollution of road surface sediments in different cities both home and abroad was introduced.The main type and content of heavy metal in road surface sediments together with its occurrence were summarized and compared.The bioavailability of the heavy metal was discussed.The influencing factors of heavy metal in sediment as well as its migration and transformation process were all analyzed.And the source of heavy metal was judged.Based on this,the development trend of the study on heavy metal pollution and the problems to be solved were pointed out,and the suggestions for controlling the pollution were proposed.
