摘　　要：为了解重金属污染情况,分析了个旧牛坝荒尾矿库土壤以及南瓜可食用部分、不可食用部分Zn、Cu、Pb、Cd、Mn、Fe元素含量。结果表明,个旧牛坝荒尾矿库土壤Cd元素污染最为严重,Zn元素污染相对最小。南瓜不可食用部分比可食用部分更易吸收累积重金属元素。In order to understand heavy metal contamination, Zn, Cu, Pb, Cd, Mn and Fe content in Niubahuang tailings dam soil and pumpkin＇ s edible part and unedible part were measured. The results showed that soil pollution of Cd element in Niubahuang tailings dam was the most serious. The minimum of pollution was Zn element. The accumulation of heavy metal in the unedible part was more serious than that in the edible part.
