尖山河小流域尖山河重金属分布

The Distribution of Heavy Metals in Jianshan River of Jianshan River Watershed

    摘要
  • 摘要: 针对尖山河小流域的重金属污染，在尖山河设置12个取样点，取样后进行ICP实验，研究尖山河重金属的分布情况。结果表明：尖山河水体中Co、Mn和Zn的含量变化不大，比较稳定。As、Cd和Zn污染较小，Cr、Cu、Mn和 Ni 的均存在不同程度的污染，但是符合I、II类饮用水质标准；Co和Pb分别是V类和超过V类水质标准。尖山河水体中As、Co、Cr、Cu、Mg、Mn、Ni、Pb、Zn的溶解态的含量分别是其总量含量的0% 、8020%、7547%、8295%、7073% 、9608% 、7083%、7508%和7857%。同种重金属的总量和溶解态含量之间的空间分布格局存在相似性；不同种重金属的空间分布格局存在差异。

     

    Abstract: Small watershed of the Jianshan River has been suffered heavy metal pollution, To counter this tendency, we took samplings from 12 plots and conducted ICP experiment to investigate the distribution of heavy metal The results showed that the pollution of As, Cd and Zn in Jianshan River had little change and relatively stable, and Cr, Cu, Mn and Ni have different degrees of pollution, but they all measured up to the I and II class drinking water quality standards; Co and Pb were V and over V class water quality standards relatively.The dissolved content of As、Co、Cr、Cu、Mg、Mn、Ni、Pb、Zn in Jianshan River were the total amount of 0%,8020%,7547%,8295%,7073%,9608%,7083%,7508% and 7857%, respectively. The patterns of spatial distribution and dissolved state of the total amount of same heavy metals were similar. However, the patterns of spatial distribution of different heavy metals were difference.
