The result shows that Co and Cu are associated with exchangeable fractions, which represents stonger mobility;Pb in iron-manganese fraction represents stonger potential mobility;Zn and Cr existed in oxidizable and residual fraction and Ni in residues represents weak mobility or immobility.

研究结果表明：Co、Cu、Mn存在可交换态，表现有相对较强的迁移性和生物可利用性；Pb主要以还原态的形式存在，表明具有较强的潜在危害性；Zn、Cr主要以氧化态和残渣态形式存在，Ni主要以残渣态的形式存在，这些元素的迁移性较弱。

The results showed that the heavy metals in various mediums were mainly Cu and Ni, and those concentrations were, in the descending order, in ditch, tailings, slagheap and cultivated soil. In the tailings and the sludge of the ditch, the concentrations of Ni were obviously higher than those of Cu. Whereas, in the soil and the weathering and atmospheric deposition of the waste slagheap surface, the concentrations of Cu were higher than those of Ni. This means that in the first two mediums, Cu and Ni mainly originated from the tailings, while in the latter two mediums, Cu and Ni mainly came from the atmospheric deposition of airborne particles of the smelting. Cr and Zn were mainly in residual fraction, Cu was mainly in oxidizable and residual fraction.
