| 摘 要： | 滨海高速公路径流作为沿海城市金属污染源之一受到国内外关注。青岛市青银高速公路路面径流金属Cr、Cu、Zn、Hg及Pb分析表明,青岛高速公路路面径流水质较好,基本符合国家V类水质标准。初期径流水质中污染物浓度较高,随着降雨冲刷强度突然增大,出现"二次冲刷"现象。结合主成分分析推知径流中Cr、Cu、Zn及Cd主要来源于大气沉降,而Hg与Pb主要来源于大气的道路交通污染。

| Abstract: | As mental pollution sources of coastal city,the coastal highway runoff gets the domestics and foreign attention.Sampling and monitoring of rainfall-runoff events from Qingyin Highway in Qingdao were conducted to measure the concentrations of the metals.Results showed that all indices of water quality of Qingdao Highway runoff already reached standard-V of Environmental Quality Standard for surface water.There was higher concentration of pollutant in initial highway runoff.With rainfall intensity strengthen instantly,second flush effect appeared.Correlation analysis and principal component analysis of the pollution indices in highway runoff suggested that Cr,Cu,Zn,and Cd were mainly from atmospheric deposition,the resources of Hg,Pb were road traffic pollution. |
