Accumulation of heavy metals in soils is likely to result in the increases of heavy metal exports to waters. The contents and fractions of heavy metals in soils directly influence the transport of the metals. However, minimal information is available on relation between metal concentration in runoff and fractions of metals in the soils. In this study, field monitoring and leaching experiment were conducted to study metal concentrations in surface runoff and metal leach ability of the 13 soils with different levels of the metals. The metals in the soils were characterized using sequential fractionation and chemical extractions. The results indicated that the metals in runoff and leachates were mainly originated from exchangeable and water soluble fractions of the metals in the soils. There were no significant correlation between metal concentrations in runoff and total metals in the soils. Extractable metals using 0.01 mol/L CaCl_2 and 1 mol/L NH_4OAc were significantly correlated with metal concentrations in surface runoff, and could better predict potential runoff of heavy metals from the soils.
