摘要
采用原子吸收光谱法,对乌鲁木齐市城区3个采样点的两次降雨过程中采集的路面径流进行了重金属Zn、Pb、Cd、Cu和Ni的含量分析。结果表明,道路径流中Zn、Pb、Cd污染较严重,但随着时间的推移,它们在雨水径流中的含量逐渐减少,符合"浓度初期冲刷"规律。
Atomic absorption spectrometry is used to analyze content of heavy metals such as Zn,Pb,Cd,Cu and Ni in road surface runoff from 3 sampling points in urban area of Urumqi city during two rainfalls.The results indicate that pollution of Zn,Pb and Cd in road surface runoff is serious,and the contents of such heavy metals in rain runoff decline after an elapse of time,which conforms to the rule of ＂first flush＂.
