摘要
通过采集2014年9月28日青岛市4个不同功能区降雨径流样品,监测其重金属Cd、Cu、Pb、Zn的含量,并分析重金属之间的相关性、事件平均浓度(EMC)和初期冲刷现象等。结果表明:石油化工区降雨径流中Cd、Cu、Pb之间具有显著相关性,并且Zn、Cu、Pb之间亦具有显著相关性;重金属Cd、Pb是降雨径流中主要污染物,Pb具有交通强度越高含量越高的特点,Cd具有距离石油化工区越远含量越低的特点;降雨径流中Cd、Cu、Pb、Zn的初期冲刷效应不仅与汇水面积、下垫面材料有关,而且与重金属的类别有关。
The rainfall runoff samples were collected from four different functional areas of Qingdao on September 28th, 2014, the content of Cd, Cu, Pb, Zn were tested, and the correlation between these heavy metals, the event mean concentration （abbr. EMC） and the first flush phenomenon were analyzed. Results showed that there was a significant correlation between Cd, Cu and Pb in the rainfall runoff from the petro-chemistry industry area, and the same in Zn, Cu and Pb. Cd and Pb were the main pollutants in the rainfall runoff. High content of Pb in the rainfall runoff occurred with great traffic intensity, while low content of Cd was in far away petro-chemical area. The first flush effect of Cd, Cu, Pb and Zn in the rainfall runoff were related not only with the catchment areas and underlying surface materials, but also with different heavy metals.
