在受金属污染的农业土壤上生产的作物可能通过食物链对人类产生慢性毒性。为评价我国南方农业土壤和大豆重金属污染状况，采集了我国南方17个采样点的30个大豆籽粒样品和17个大豆田土壤样品，采用石墨炉原子吸收分光光度计测定了样品中重金属含量。采用综合污染指数法评价样品是否受到Cd、Pb、Zn和As的污染。结果表明，有12个样品的Cd、2个样品的Pb、2个样品的Zn和2个样品的As含量超过土壤最高允许值。综合污染指数表明，17个土壤样品中有11个受到金属污染。大豆籽粒中Cd、Pb、Zn和As的含量分别为0.11 ~ 0.91、0.34 ~ 2.83、42 ~ 88和0.26 ~ 5.07 mg kg-1，表明30个大豆籽粒样品均受到Pb、Pb/Cd、Cd/Pb/As或Pb/As的污染。总之，我们的研究提供了证据，金属污染是中国南方农业土壤和大豆的一个重要问题。
Crops produced on metal-polluted agricultural soils may lead to chronic toxicity to humans via the food chain. To assess metal pollution in agricultural soils and soybean in southern China, 30 soybean grain samples and 17 soybean-field soil samples were collected from 17 sites in southern China, and metal concentrations of samples were analyzed by graphite furnace atomic absorption spectrophotometer. The integrated pollution index was used to evaluate if the samples were contaminated by Cd, Pb, Zn and As. Results showed that Cd concentration of 12 samples, Pb concentration of 2 samples, Zn concentration of 2 samples, and As concentrations of 2 samples were above the maximum permissible levels in soils. The integrated pollution index indicated that 11 of 17 soil samples were polluted by metals. Metal concentrations in soybean grain samples ranged from 0.11 to 0.91 mg kg(-1) for Cd; 0.34 to 2.83 mg kg(-1) for Pb; 42 to 88 mg kg(-1) for Zn; and 0.26 to 5.07 mg kg(-1) for As, which means all 30 soybean grain samples were polluted by Pb, Pb/Cd, Cd/Pb/As or Pb/As. Taken together, our study provides evidence that metal pollution is an important concern in agricultural soils and soybeans in southern China.
