| 摘 要： | 以位于南京市城市边缘带的六合区蒋家湾蔬菜基地为研究区,对土壤进行了高密度样品采集与分析,阐明了该地区土壤重金属污染状况并进行了相关评价。研究数据表明:该区As、Cu、Zn、Cd、Cr、Pb等6种重金属在土壤中的含量均低于背景值,而土壤中Hg含量严重超标,为该地区主要的土壤污染因子。Hg进入土壤的途径可能包括蔬菜地高强度的农化产品投入、工业和生活垃圾施用,但没有证据显示与灌溉水源有关。

| Abstract: | A vegetable production base in the periurban region of Nanjing was chosen for assessment of soil pollution by hazardous metals, totally 23 topsoil samples were collected and analyzed for heavy metal contents. The data obtained indicated that the contents of Cu, Pb, Zn, Cr, Cd, and As in the soils were lower than their regional background values. However, Hg content in the studied soils greatly exceeded its background value, demonstrating significant soil pollution. It was thought that Hg pollution resulted from intensive application of Hg-containing agrochemicals during long-term vegetable planting in this area. |
