摘要
[目的]研究宜春市区樟树叶片中重金属含量。[方法]以宜春市区道路旁樟树叶片作为研究对象，经消解后采用电感耦合等离子体（ICP －OES）法测定樟树叶片中重金属含量，通过污染指数等级对每个采样点大气重金属污染程度进行评价。[结果]重金属 Pb、Cd、Cr、Mn、Zn、Cu 的平均含量分别为0．790、0．699、16．870、44．030、456．290、12．410 mg ／kg。其中，Zn 的含量高，但污染程度较小，Mn 相对含量较小，但污染程度较小。[结论]整体来看，宜春市植物受到大气重金属污染较小。
Abstract
Objective] The aim was to study heavy metal content in camphor tree leaves in Yichun City.[Method] With camphor tree leaves in Yichun City as study object, after digestion, ICP -OES method was adopted to determine heavy metal contents, through pollution index grade, heavy metal pollution degree in each sampling site was evaluated.[ Result] The average content of Pb, Cd, Cr, Mn, Zn, Cu was 0.790, 0.699, 16.870, 44.030, 456.290, 12.410 mg /kg.The content of Zn was high, but the pollution degree was slight; the relative content of Mn was low, the pollution degree was low.[Conclusion] In general, Yichun plants are less polluted by heavy metals in the atmos-phere.
