| 摘 要： | 本文通过对街道灰尘中铬、镉、铅三种元素赋存状态研究、铬、铅在街道灰尘中以残渣态为主，镉以有机质结合态为主。虽然铬、铅、镉存在形式稍有差异，但其在街道灰尘中主要以矿物质的形态存在，说明其比较稳定，不易迁移转化，对环境的危害比较持久。在治理措施上应有早遏止微量元素向环境中排放，以免其与灰尘发生相互作用对环境造成长期的危害。

| Abstract: | Based on the research of occurrence state of Cr,Cd and Pb in the dust, the paper points out that the main state of Cr and Pb is remnant dregs, the main state of Cd is organic combination, although the difference of their state is very less, their main existent form is mineral too, This indicates they is very stable, it is not easy to move and trans form, their harm is lasting to environment, the measure of administration is that they is checked to dis charge into environ ment, let not they interplay to harm permanently environment. |
