The waters with salinity from 10 to 23 comprise the main removal region of ion and particulateforms of heavy metals in the Changjiang estuary.The positive correlationships between Zn,Cd,Pb,Cuand the reciprocal of transparency,COD and chlorophyll-a showed that the removal of heavy metalsclosely correlate with the distribution of suspensions,the adsorption of organic materials and theassimilation by organisms.The removal of heavy metals in the Changjiang estuary water were consistentwith the sedimentation rate of the sediments in these waters,sediment types and the distributions ofheavy metals contents in the sediments.
