This paper discusses the adsorption and desorption of heavy metals at Jinzhou port sediment via the static and dynamic experiments of sediment which dip in seawater in the lab, and it is important to know the pollution problem of heavy metals in seawater. Using the heavy metals in Wuli river sediment of Huludao city as the parallel experiment, we make a study of the transportation of heavy metals deeply at seawater-sediment interface. And at the effect of ocean current, the release of heavy metals for interstitial water affects the sea environment. The concentrations of limited release and equilibrium are both under the first seawater standard when sediment desorb. But the sediment of Wuli River has became secondary pollution for water and will be a new problem of environment contamination.
