| Abstract: |
| The authors have determined the distributions of Ph, Cu and Cd ia surface sediment, acid-soluble fraction and interstitial water of the Changjiang Estuary and analysed the relationship between them and some environmental parameters, finding that there exists a quasi-equilibrium between the interstitial water and the sediment. The distribution of Pb or Cu in both phases it controlled mainly by the adsorptioa-desorption and deposition-solution processes of HFO1) and org.2) in the sediments, whereas Cd is mainly controlled by the depoahisn-Jolution process of CdS. The sedimentation mechanism of Ph, Cu and Cd in the Changjlang Estuary is preliminarily proposed. |
