| 摘 要： | 文章为了分析东莞市在快速工业化和城市化情况下城镇周边菜地重金属积累现状、污染程度及其分布特点，对东莞市6个镇区46个菜地样地土壤重金属进行了调查、检测和分析。结果发现Zn、Cu、Cd和Pb检测值大都超过广东省背景值，而cd污染最重，67．4％的样地综合污染已经超过了警戒水平。研究发现菜地土壤重金属污染虽然有某种复合型，但程度较弱，检测元素大多没有关联性，结果也表明Zn、Cu、Cd和Cr的分布不受镇区位置的影响，而可能更多是受采样点微环境的影响。

| Abstract: | To analyze the accumulation status,pollution degree and distribution of heavy metals in vegetable fields of suburban of Dongguan which are undergoing fast urbanization and industrialization,soil samples from 46 plots belonging to 6 towns with different industry types were collected,and the contents of Zn,Cu,Cd,Pb and Cr in them were tested and analyzed.The results indicated the contents of Zn,Cu,Cd and Pb of more than 90% plots exceeded the background values of Guangdong,single pollution indexes of Cr and P... |
