摘　　要：土壤是环境要素的重要组成部分,它承载着环境中大约90%的来自各种途径的污染物。在土壤———植物系统中,重金属污染具有多元性、隐蔽性、一定程度上的长距离传输性和污染后果的严重性。通过有选择地调查、监测、分析,初步搞清楚了重金属离子(Hg2+、Cr6+、Pb2+、Cd2+)在粮食蔬菜中的含量,进行了分项评价和总体评价,同时针对治理方法提出了建议。Soil, which receives 90% pollutant of various sources in environment, is an essential component of environment. Heavy metallic ions are of multi-factor,concealment,conductivity in specific scale and severe pollution.The paper briefly analyzed content of heavy metallic ions((Hg^(2+),Cr^(6+),Pb^(2+),Cd^(2+)) in vegetables and foods .Characteristic,distribution of pollutants,evaluation,and total evaluation were analyzed simultaneously and constructive suggestion was proposed for treatment of the pollution.
