摘　　要：为研究麻江蓝莓叶中铅、砷、铬、镉和铜的含量及污染程度。采用ICP-MS分别测定了麻江县6个蓝莓基地18件蓝莓叶中的5种重金属元素含量。并采用单因子污染指数法对蓝莓叶中铅、砷、铬、镉和铜5种重金属含量及污染程度进行了评价。结果表明,蓝莓叶中铅、砷、铬、镉和铜的平均值分别为1.2±0.4 mg/kg、4.4±0.2 mg/kg、0.7±0.6 mg/kg、0.0±0.0mg/kg和3.9±0.6 mg/kg。单因子污染指数评价结果显示,研究区蓝莓叶中As均已超标,达中度污染水平,其他重金属元素均处于清洁水平。To study the content and pollution degree of Pb,As,Cr,Cd and Cu in the leaves of Majiang blueberry.The contents of 5 heavy metals in 18 blueberry leaves from 6 blueberry bases in Majiang county were determined by ICP-MS.The content and pollution degree of 5 heavy metals in blueberry leaves were evaluated by single factor pollution index method.The results showed that the average values of Pb,As,Cr,Cd and Cu in the leaves of Majiang blueberry were 1.2±0.4 mg/kg,4.4±0.2 mg/kg,0.7±0.6 mg/kg,0.0±0.0 mg/kg and 3.9±0.6 mg/kg,respectively.The results of single factor pollution index showed that Arsenic concentration in blueberry leaves of the study area had exceeded the standard,reaching the level of moderate pollution,but other heavy metal elements were in the clean level.
