Abstract: The form of copper occurrence in contaminated soil in a smeltery site was discussed comparatively by continuous chemical digestion, with the coefficient of biologic effectiveness to copper calculated. The results showed that the distributive form of copper in the copper smelting area is in an order of RES>CA>OM>Fe-Mn>EXC and WS, while in the zinc smelting area the distributive form of copper is in an order of RES>OM>CA>Fe-Mn>EXC and WS. It showed that copper is mostly in the form of residue, i.e., the 63.4% in the soil of smelting area and 38.5% in that of zinc smelting area. The biologic effectiveness coefficients to heavy metals in the soil of both areas are in an order of K3>K2>K1, K2>K3>K1 correspondingly as a calculated result.
