摘　　要：[目的]研究某冶炼厂周边蔬菜中重金属的累积分布及其污染程度。[方法]以某冶炼厂周边的蔬菜(茄子、辣椒、黄瓜)和土壤为研究对象,测定其体内三种重金属(Cd,Pb,Cu)的含量。[结果]土壤中重金属含量Cu>Pb>Cd;不同蔬菜种类,体内的重金属含量不同;同一蔬菜体内,重金属的累积分布也不同。[结论]蔬菜受到重金属的复合污染,不能被人畜食用。[Objective] The aim was to study the cumulative distribution and assessment of heavy metals in vegetables around a metal production plant.[Method] Soil and vegetables（eggplant,pepper,cucumber）were took around a metal production plant as object of study,contents of three heavy metals（Cd,Pb,Cu）were determined.[Result] Contents of three heavy metals in soil were CuPbCd;Contents were different in vegetables with different vegetables;Cumulative distribution of heavy metals were different in the same vegetables body.[Conclusion] Vegetables were combined pollution by heavy metals,couldn＇t be taken by person and livestock.
