In the Fandong (FD) and Zhongxin (ZX) villages, which are near the Dabaoshan mineral deposit, concentrations of Pb (0.34 mg kg^(-1) for FD), Cd (0.23 mg kg^(-1) for ZX) and Cr (1.14 and 1.75 mg kg^(-1) for FD and ZX, respectively) in the seeds of soybean exceeded the tolerance limit set by Chinese standards. The estimated daily intakes (EDIs) from consumption of soybean seeds for FD inhabitants were 0.570, 0.170, 38.550, 142.400, 1.910 and 14.530 μg d^(-1) kg^(-1) boby weight for Pb, Cd, Cu, Zn, Cr and Ni, respectively. Our results indicate that soybeans grown in the vicinity of the Dabaoshan Mine accumulate some metals, and the seeds pose a potential health risk to the local inhabitants. 关键词：重金属污染土壤大豆种子大宝山矿中国 FD-1 健康风险铅浓度 EDIS
