| 摘 要： | 采集了上海市交通主干道金沙江路距路肩不同距离（近站位、远站位）近地表大气颗粒物样品24个,使用全谱直流电感耦合等离子光谱仪测定其As、Cr、Cu、Pb、Mn、N i等重金属元素浓度。结果表明,大气颗粒物的质量浓度及其重金属绝对浓度在每个采样点的近站位均高于远站位,而部分大气颗粒物的重金属相对浓度表现为远站位高于近站位;金沙江路沿线由外环到内环方向,大气颗粒物的质量浓度有明显降低的趋势,而大气颗粒物重金属含量具有明显的升高趋势,这与机动车的行驶速度是相关的。

| Abstract: | Along a traffic mainline,Jinshajiang Road 24 atmospheric particulate samples were collected,and the concentration of heavy metal(As,Cr,Cu,Pb,Mn,Ni) were measured by ICP-OES.The results showed that:(1) The mass concentration of particulate matter at the sampling close stations were higher than far stations,while the relative concentration of heavy metals at far stations was higher than the close stations.(2)At the Jinshajiang Road along the direction from the Outer Ring to the Inner Ring,the concentration of... |
