摘要
采用重金属单项污染指数和综合污染指数评价方法,对郑州市近郊毛庄、姚桥和花园口3个蔬菜生产基地土壤和蔬菜中重金属(Cu,Cr,Pb,Cd)含量进行调查与分析,以无公害蔬菜标准评价蔬菜重金属污染状况。结果表明,郑州市近郊蔬菜基地土壤目前尚未受到重金属污染,而蔬菜的重金属综合污染指数大部分高于3.0,污染比较严重,这说明蔬菜对重金属的富集能力较强。
The contents of heavy metals （Cu, Cr, Pb, Cd） in the soils and vegetables in the main vegetable production areas of Maozhuang, Yaoqiao and Huayuankou in the suburbs of Zhengzhou were examined and analyzed to evaluate the status of heavy metal contamination by means of single pollution index and concentrative pollution index based on the standards for pollution-free vegetables. The results showed that the soils tested was not yet polluted by heavy metals, but most pollution index in vegetables were over 3.0, indicating that the vegetables have the ability enriching heavy metals.
