摘要：

Heavy metals Cd, Zn, Cu, Pb, Cr and Ni in the paddy field which had contaminated by Cd and Pb, were re-examined. Soil samples were collected from panels of a hectare of paddy field in Luchu county of Tauyuan prefecture, Taiwan. Soil samples were taken from ten spots in each panel in regular 25 m distance (length and width), and mixed through for analysis. Soils were sampled from surface down to 30 cm depth. Heavy metals in the soil samples were extracted with 0.1 M HCl and the extracts were analyzed by atomic absorption spectroscopy. Maximum amounts of metal are found : Cd 10.6 ppm, Zn 84.0 ppm, Cu 99.7 ppm, Pb 58.1 ppm, Cr 2.95 ppm and Ni 16.6 ppm.
