| 摘 要： | 水体底泥污染是世界范围内的一个环境问题,污染物通过大气沉降、废水排放、雨水淋溶与冲刷等途径进入水体,最后沉积到底泥中并逐渐富集,使底泥受到污染。千岛湖不同监测点底泥Cu、Zn、M n、Pb、Cd、A s、Hg等重金属含量存在差异。大坝前、毛竹源和三潭岛监测点M n、A s和Hg含量较高。不同采样点,底泥重金属污染度有差异,表现为毛竹源>三潭岛>航头岛>茅头尖>大坝前>排岭水厂>街口,毛竹源测点底泥重金属污染风险最高,街口重金属污染风险最低。

| Abstract: | Water heavy metal pollution is a worldwide environmental problem,contamination enters into the water-body through atmosphere sedimentation,wastewater discharging,rainwater drenching and dissolving and eroding,and finally deposit in the mud and gradually enriched,make the bottom mud polluted.The content of heavy metals such as Cu,Zn,Mn,Pb,Cd,As,and Hg in the bottom mud of the Qiandao Lake varies at different monitoring spots.The content of Mn,As and Hg at the dam,Maozhuyua,and Santan Island is relatively higher than that at other spots.The degree of heavy metal pollution of the bottom mud at different sampling spots varies.The pollution risk of heavy metals in the bottom mud at Maozhuyuan is the highest,while that at Jiekou is the lowest. |
