摘　　要：对博爱农场和中马村矿的土壤及玉米中Cu、Cr、Pb、Zn的调查研究和对比分析表明,博爱农场三分场土壤及玉米中的重金属略高于四分场;农场除三分场玉米由于受到外界影响Pb超标以外,其他重金属在玉米中的含量均低于国家粮食限量标准;中马村矿土壤重金属整体高于博爱农场,玉米中Pb含量全部超标,其他重金属在玉米中的含量也有部分超出正常标准值。Contents of four heavy metals, Cu, Cr, Pb, Zn in corn and soils in a Boai farm and Zhongmaeun coal mine in Jiaozuo were analyzed and evaluated. The results indicated that the heavy metals in the third plot was higher than the fourth in the farm, probably due to the outside impact, while Pb in corn samples collected from the third plot exceeded the official standard. Fortunately, the contents of the heavy metals for the rests were all under the official standard. Furthermore, the contents of heavy metals in whole soils taken from Zhongmacun coal mine were higher than that from Boai farm. Notably, the contents of Pb in corn samples were all less than the official standard. However, the contents of heavy metals in corn samples exhibited a climbing trend.
