• the Pb/Zn smelting slag
• heavy metal pollution
• risk evaluation

Heavy metals(Pb, As, Cd, Cr, Cu, Ni and Zn.) in the soil sample in the vcinage of the Pb/Zn smelting slag were analyzed when the sample were digested by nitric acid-hydrogen peroxide-hydrofluoric acid series through using the Hydride generation-Atomic absorption Spectrometry method and Flame-Atomic absorption Spectrometry method. Elevated levels of Zn and heavy metals were found in the tailing. Mean concentrations of Pb, Zn and Ni in agricultural soil were higher than the permissible level. The result indicated that the heavy metal content for Pb and Zn in the soil surface of Point 1,3 was higher than the value from (Standard of Soil Quality Assessment for Exhibition Sites). The distribute of heavy metals presents a kind of decreasing trend from superior surface to inferior surface. And then on the basis of the location's future application, population suffered from harm and the approaches of the hazard. Carcinogenesis risk evaluation method and non-carcinogenic risk evaluation method were adopted to evaluate the heavy metal contamination's harm to human body.
