Survey and Evaluation of Heavy Metal Contamination of Soil and Vegetables in the Vegetable Bases in Suburbs of Nanchang

通过对南昌市近郊扬子洲、蒋巷两主要蔬菜生产基地土壤和蔬菜中重金属(Cu、Zn、Pb、Cd)含量的调查与分析,采用重金属单项污染指数和综合污染指数评价方法,对土壤重金属污染状况进行评价,以无公害蔬菜标准评价蔬菜重金属污染状况,结果表明,南昌市近郊蔬菜基地土壤和蔬菜目前尚未受到重金属污染。

The contents of heavy metals （Cu,Zn,Pb,Cd） in the soil and vegetables in the main vegetable production areas of Yangzizhou and Jiangxiang in the suburbs of Nanchang were examined and analyzed to evaluate the status of heavy metal contamination. The evaluation was carried out by means of single pollution index and concentrative pollution index, and the vegetables were evaluated by terms of the standards for pollution -free vegetables. The results showed that the soil and vegetables were not yet polluted by heavy metals in the vegetable production areas in the suburbs of Nanchang at present.
