Abstract

Based on the 45 rainfall runoff samples that are collected from Qingdao residential area after the raining of July 22, 2014 and September 28, 2014, this paper tests the contents of heavy metals Cd, Cu, Pb, Zn and Mn. And based on the test results, this paper further analyzes event mean concentration (abbr. EMC), first flushing effect, and the correlation of these heavy metals. Experimental results show that the EMC of most of heavy metals are in low level, expect for the one of Cd collected on September 28, 2014. Therefore, the quality of most rainfall runoff samples is good. The first flushing effect of heavy metals in rainfall runoff of July 22, 2014 is obvious. In contrast, the first flushing effect does not appear in the rainfall runoff of September 28, 2014. The correlation between Cu, Pb, and Zn in rainfall runoff is strong, while the one between Cd, Mn and other heavy metals are weak.
