摘　　要：用原子吸收分光光度法测定了仁怀市土壤中有害重金属元素铅的含量。实验结果表明:仁怀市各乡镇土壤pH处于弱酸性至中性之间,土壤中重金属铅含量为29.81—64.70mg/kg,平均含量为41.40mg/kg;土壤中重金属铜含量为22.49～93.44mg/kg,平均含量为44.02mg/kg,处于国家土壤环境质量一级标准和二级标准之间,仁怀市抽样土壤环境质量良好。The toxic heavy metal element Pb of soil sample in Ren Huai city is determined by Atomic Absorption Spectrophotometry. The experimental results show that the pH of soil in township of Ren Huai city between weak acid and neutral, Pb content is 29.81- 64.70 mg/kg and average content is 41.40 mg/kg. Cu content is 22.49-93.44mg/kg and average content is 44.02mg/kg. The soil quality is between the first grade of National Soil Environmental Quality Standard and the second grade, which implies that the sample of soil in Ren Huai city environmental quality is good.
