| Abstract: | The waters with salinity from 10 to 23 comprise the main removal region of ion and particulate forms of heavy metals in the Changjiang estuary. The positive correlationships between Zn, Cd, Pb, Cu and the reciprocal of transparency, COD and chlorophyll -a showed that the removal of heavy metals closely correlate with the distribution of suspensions, the adsorption of organic materials and the assimilation by organisms. The removal of heavy metals in the Changjiang estuary water were consistent with the sedimentation rate of the sediments in these waters, sediment types and the distributions of heavy metals contents in the sediments. |
