• The present study analyzed the distribution and pollution characteristic of heavy metals in surface sediments from the Liaodong Bay,and then evaluated the potential ecological risk caused by heavy metals to learn the environment quality of sediments.Content distributions of heavy metals including As,Cu,Cd,Cr,Hg,Ni,Pb and Zn in surface sediments from the Liaodong Bay were studied.Simultaneously,the potential ecological risks of these heavy metals were analyzed by the index method on potential ecological risk and geoaccumulation index(I geo )and Environment quality in surface sediments from the Liaodong Bay was evaluated.The contents of As,Cu,Cd,Cr,Hg,Ni,Pb and Zn in surface sediments appeared higher near the Huludao,southeast sea of the Liugu estuary in the southwest part,near sea in the western.The results of pollution assessment by index of geoaccumulation and the potential ecological risk index were almost the same.The order of ecological risk of these heavy metal is as follow:Cd>Hg>Cu>Pb>As>Zn>Ni>Cr,with C
