| 摘 要： | 对西安市路面积尘粒径分布和不同粒径中矿物质量组成的研究表明,路面积尘质量主要集中在30～50目(0.59～0.297mm),其次在140～160目(0.105～0.088mm),<200目(<0.074mm)的粒径中。同时给出不同粒径中矿物的分布特点,较细粒径中矿物含量稍高于较粗粒径中的含量。细颗粒表面积大,更易吸附较多的有毒有害物质,对环境的影响较明显。

| Abstract: | Study on road dust with grain diameter distribution and mineral composition of various grains in Xi'an demonstrated that road dust mainly existed in grains with a diameter of 30～50 mesh(0.59～0.297mm),secondly in 140～160 mesh(0.105～0.088mm)and less than 200 mesh(0.074mm).Distribution of minerals in different diameter grains indicated that the quality of mineral in mini-diameter grains was higher than those in maxi-diameter grains.Mini-diameter grains were easy to adsorb more nocuous substance than maxi-diameter ones because of their big surface areas,which has obvious impact on environment. |
