城市道路雨水径流铅污染研究分析

摘要

城市道路使用频繁，含铅汽油、轮胎磨损、运输漏失等使得重金属铅以离子态或化合态赋存于路面上，并经雨水冲刷进入雨水径流中，随之转移至人类生活的各个领域。由于铅对人类的潜在性危害，人们对去除道路雨水径流中铅的研究也日渐加深。本文通过对径流中重金属铅污染的研究，分析了城市道路径流雨水中铅污染的分布特征、迁移转化过程，给出了道路径流雨水中重金属铅去除的几种方法。%Heavy metals were introduced in the urban road on ionic state or combining state and would be washed off into the road runoff with the frequent use of the urban road,the use of leaded petrol,the abrasion of tire and the leakage of transport carriage which can be able to migrate to the areas of human living. more and more attentions were paid on the lead pollution in the road runoff due because of its potential harm to people. The research progress of the lead pollution in urban road runoff was analyzed in this paper through studying the lead pollution in urban road runoff,and recommended some disposal methods through the source,migration and the end of the lead pollution in urban road runoff.
