| Abstract: | Two evaluation methods,including the Pollution Load Index(IPx) and the Potential Ecological Risk(RI),were adopted to analyze surface and profile distributions and pollution character of heavy metals(Mn、Pb、Cu、Zn、Cr and Cd) in sediments in Xiushan section of Meijiang river.The results show that the concentrations of these six metals in the surface sediments decrease in order of Mn >> Zn > Pb > Cu > Cr > Cd.Only the contents of two metal elements,Zn and Cu,decrease along with increasing depth,while other metals display no regularity.The values of IPx(2.7) and RI(> 600) indicate this region was heavily contaminated by these six heavy metals,and there are serious ecological risks for local organism. |
