| 摘 要： | 本文以成雅高速公路为研究对象，采集公路两侧大气颗粒物样品，通过微波消解——火焰原子吸收法测定大气颗粒物中铅、镉、铜、锌的含量。研究表明，成雅公路两侧距路肩200m范围内大气颗粒物已受不同程度的铅、镉、铜、锌污染，其中重金属含量Pb〉Zn〉Cu〉Cd，并获得成雅高速公路两侧大气颗粒物中重金属污染的分布规律。

| Abstract: | In this paper, the atmospheric particulate were sampled from both sides of the Cheng-Ya expressway. The concentrations of lead, cadmium, cuprum and zinc were determined by Microwave digestion-Flame AAS method. The results showed that the air within 200 meters from the both road shoulders had already been polluted by heavy metals at different levels, with the concentration trend as follows ： lead 〉 zinc 〉 cuprum 〉 cadmium. And the distribution of heavy metal pollution to the air on both sides of the Cheng-Ya expressway was discussed. |
