| 摘 要： | The five chemical associations ofheavy metals have been extracted continuously using the Tessier extracting method.Results show that Cu,Pb,Fe,Zn and Cr in the sediments are mainly distributed in residual fraction,while the major chemical association of Mn is carbonates.Carbonate heavy metals are converted into Fe-Mn oxides in autunm.And in the low tidal flat,after carbonates have changed into ionic heavy metals,some of the elements are transported to the overlying water,Cu,Pb,Fe and Mn have good correlations with each other,and Zn,Cr also show their similarity of chemical behavior in the sediments.

| Abstract: | The five chemical associations of heavy metals have been extracted continuously using the Tessier extracting method. Results show that Cu, Pb, Fe, Zn and Cr in the sediments are mainly distributed in residual fraction, while the major chemical association of Mn is carbonates. Carbonate heavy metals are converted into Fe-Mn oxides in autumn. And in the low tidal flat, after carbonates have changed into ionic heavy metals, some of the elements are transported to the overlying water. Cu, Pb, Fe and Mn have good correlations with each other, and Zn, Cr also show their similarity of chemical behavior in the sediments. |
