Abstract
Research was made on the spatial distributions of heavy metals (Cu, Ni, Cr, Zn, Cd and Pb) in the sediments from a northern city of China. Based on the experimental data and the average enrichment factor (AEF) in the study area were evaluated by the potential ecological average enriched factor. The results showed that (1) Cd, Cu and Zn were the main risk factors and Ni, Cr belong to the mild pollution.(2) Different heavy metals have great differences in different layers of the sediment. (3) The third sampling point is the main heavy metals discharge side and the main pollution area.
