| 摘 要： | 对长春地区部分农田土壤及玉米中重金属含量进行调查和分析。结果表明，研究区域内土壤中Cu、Zn、Ni、Pb、Cd、Cr、Hg、As 8种重金属含量符合土壤环境质量标准的要求；相应地块玉米中Cu、Zn、Pb、Cd、Cr、Hg、As 7种重金属含量符合粮食重金属元素限量要求，达到食用标准；土壤和玉米中Pb、Cd、Hg含量相关性不显著，Ni、Cr、As含量相关性显著，Cu、Zn含量相关性极显著。

| Abstract: | The content of heavy metals in soil and in corn of port farmland in Changchun were determined in this paper. The results showed that the content of Cu, Zn, Ni, Pb, Cd, Cr, Hg and As in farmland soil was accord with the environmental quality standard for soil, and the content of Cu, Zn, Pb, Cd, Cr, Hg and As in corn was accord with the limits of heavy metals in cereals also. The relativity of content of Pb, Cd and Hg in soil and corn is not obvious, but the content of Ni, Cr, As, Cu and Zn in soil and corn expressed marked correlation or very marked correlation. |
