| 摘 要： | 对广利灌区两市一县土壤和小麦中镉、汞、铅、砷重金属进行了分析，结果表明广利灌区土壤和小麦受镉、汞、铅、砷污染程度较小，土壤属于清洁，小麦食用安全。土壤中重金属区域差异比较明显，武陟县和济源市土壤中砷含量高，沁阳市土壤中铅、镉含量高。小麦籽粒对镉的吸收积累能力大于铅，对砷和汞的吸收富集能力较小。

| Abstract: | The heavy metals such as cadmium, mercury,lead and arsenic have been analyzed in the soils and wheat in the area which is irrigated by Guangli River. The results show that the pollution of cadmium, mercury, lead and arsenic in the soils and wheat are slight and the wheat is edible. The concentration of arsenic is high in the soils of Wuzhi and Jiyuan County. The contents of lead and cadmium are high in Qinyang County. Therefore the contents of heavy metal are various in the different region. The accumulation of cadmium is higher than lead, arsenic and mercury in wheat. |
