摘要
为研究成都市土壤—植物系统铅污染状况,分析了成都市五种蔬菜及其根系土的铅含量。结果表明,土壤铅含量变化范围61 0～1 1 5 0mg/kg,均值为77 3mg/kg ,所有样品含量均超过成都市土壤环境背景值,以城东和城南污染最为严重;蔬菜中铅含量以莴笋叶最高,萝卜最低,叶菜类高于瓜果类;蔬菜污染严重区与土壤污染区差别明显,说明土壤铅和植物铅污染源不同。
The content of lead of five different vegetables and their soil samples from Chengdu city was analyzed.The average value of soil lead content is 77.3 mg/kg,in the range from 61.0～115.0 mg/kg ,the most serious polluted areas are in the east and south of Chengdu.The content of lead of lettuce leaves is topmost and the radish is lowest.The obviously discrimination of soil and plant polluted areas reveals the different polluted resources.
