| 摘 要： | 应用地质积累指数法和HaKanson生态风险指数法对月牙河9个监测点表层水体沉积物中重金属污染程度进行了连续多年的监测与实验研究。结果表明:水体沉积物中重金属的污染排列顺序是Cu>Ni>Zn>Pb,当水体沉积物大于60cm深度时其重金属污染物风险处于警戒线以下(即安全范围),检测出一个点位水体沉积物中重金属含量出现峰值现象,其中Cu污染程度为重度污染,以两种背景值为参比得出的重金属污染程度顺序相近.Cu对月牙河水体生态环境具有潜在影响的主要重金属元素。

| Abstract: | The heavy metal pollution in water bodies sediment of the Yueya River was studied with index of Geoaccumulation(Igeo)for many years with respect to their eco-environment risk.The method of potential ecological risk(PER)index presented by Lars Hakanson was also applied to analyze the accumulation coefficients,PER coefficients.The results showed that the index of heavy metals in the surface sediment of the order is: Cu>Ni> Zn > Pb..In2008,the heavy metals in surface sediment showed their peaks,the more seriou... |
