| 摘 要： | 利用等离子体发射光谱法、原子吸收光谱法、X射线光谱法等研究了厦门、漳州两市的9个土壤剖面样品中的Cu、Pb、Zn、Cd、Cr、Ni、Hg和As共8个重金属元素在剖面上的分布特征,以及Cu、Pb、Zn三种元素的全量与有效态含量在剖面上的变化特征,探讨了重金属元素垂向变化的环境意义。结果表明部分重金属元素在土壤表层有富集现象和相似的迁移和富集规律;Cu、Pb、Zn三元素的有效态与全量的相关性随着深度而变小,这表明Cu、Pb、Zn三元素的全量与有效态含量间的相关性与人类的活动关系较为密切。 |

| Abstract: | The distribution characteristics of 8 heavy metallic elements including Cu,Pb,Zn,Cd,Cr,Ni,Hg and As,and vertical variations of the total and available contents of three heavy metallic elements(Cu,Pb,Zn) from 9 soil profiles were studied in two cities of Xiamen and Zhangzhou,Fujian Province,by ICP-AES,AAS and XRF.The paper also discussed the environmental significance of these heavy metallic elements in soil profiles.The results indicated that some metallic elements exhibited similar rules of migration-enrichment in the top soil layer.The dependence of effective form and whole quantity of the three elements Cu,Pb,Zn tended to decrease with increasing depth,indicating that the correlation between the total and effective form contents of the elements Cu,Pb,Zn is closely related to human activities. |
