By the analysis of species and contents of the heavy metals in the polluted sediment in Shizi River (in the section of Yangtze River Normal College)，it is shown that Pb content in the sediment has seriously exceeded the standard because of the influence from the road along the banks of the River，and is the present principal pollutant，meanwhile，Cr and Cd exceed the standard due to randomly stacking a lot of home scraps at the gate of the College，which is worth vigilance.
