| 摘 要： | 调查了蚌埠市蔬菜重金属铅、镉、铬、砷、汞的污染现状,结果表明:除叶菜类蔬菜外,其他类型蔬菜均没有受到重金属的污染;叶菜类蔬菜中,100%样品铅含量超标,50%样品镉含量超标,镉含量平均值接近无公害蔬菜重金属限量指标;所有蔬菜无Cr、As、Hg污染;不同类型蔬菜对重金属的吸收富集能力不同,叶菜类蔬菜对重金属的吸收富集能力最强,瓜类蔬菜对重金属的吸收富集能力最弱;同一蔬菜不同部位中重金属含量差异也较大,叶片中重金属含量普遍高于其他部位。

| Abstract: | The contamination level of Pb,Cd,Cr,As and Hg in 26 kinds of vegetables in Bengbu was investigated. The results showed that among vegetables produced form market of Bengbu,except leaf vegetables,other vegetables were not contaminated. There were 100 % of the samples whose lead content exceeded the standard,the most exceeded was 2.37 times of the standard and averaged 1.6 times of the standard; and 50 % of the samples whose cadmium content exceeded the standard,the most exceeded was 2.24 times of the standard,whose average cadmium content was closed to the heavy metal index of nuisanceless vegetable in China. All vegetables are not polluted by Cr,As,Hg;The absorbability to the heavy metal of different kinds of vegetables is different,the absorbability to the heavy metal of leaf-vegetables is the strongest,but melon vegetables is the weakest. The content of heavy metal of different position of the same vegetables differs greatly,the content of heavy metal is generally higher than other position in the blade. |
