Abstract:Soil samples gathered from farmlands in the neighborhood of a smeltery were analyzed for pH, EC and contents of elements of different forms, such as N, P, K, Cu, Zn, Pb and Ni. The results showed that the soil was polluted by heavy melts. The total and extractable Cu in the soil within the radius of 100m were 182.45 mg/kg and 81.91 mg/kg, respectively, which were 9.3 times and 34 times as high as than that in the control. The distribution of heavy metals in rice in the sewage irrigated area varied from metal to metal and from part to part. Cu concentration was in the order of root > leaf-stem > rice and Zn concentration, leaf-stem > root > rice. Zn was more mobile than Cu, which was likely to accumulate in the root of rice. The concentration of Cu in the stem and leaf of rice was significantly related to Cu content in the soil of the sewage irrigated area.
