| Abstract: | Five chemical forms of Cu and Co in the suspended particles in the estuary of Chang-jiang River were determined by the chemical sequential extraction procedure. Laws governing the change and distribution of them from fresh water to salt water were described.In January, 1986, the salinity was about 7 and the suspended particles decreased sharply as most of the suspended particles are removed by precipitation. The percentage of the five chemical species of elements in the suspended particles varied within the salinity range of 0.05 to 33. Cu and Co remained mainly in residual forms.The explored forms of heavy metals in the Changjiang river could also be expressed as follows: Cu and Co in residual form were estimated to be 68% and 73%, those in precipi-tation-coprecipitation phases were 18% and 20% respectively. |
