| 摘 要： | 目的调查不同农作物的重金属含量、生物富集现状。方法以定点采样方法选取河南省新乡地区的农田土壤及其农作物,应用原子吸收光谱法检测重金属铅(Pb)、砷(As)、汞(Hg)、铬(Cr)、镉(Cd)、铜(Cu)、锌(Zn)、锰(Mn)、镍(Ni)的含量,探讨其生物富集作用。结果农作物重金属含量是粮谷类>叶菜类>非叶菜类,不同类农作物对同一种重金属元素的吸收率各不相同,Pb、As、Hg、Cr、Zn、Mn、Ni:粮谷类>叶菜类>非叶菜类;Cd:叶菜类>粮谷类>非叶菜类;Cu:粮谷类>非叶菜类>叶菜类。结论不同农作物对重金属的生物富集不同。

| Abstract: | Objective To investigate the concentration,bioaccumulation of heave metals in different crops.Methods Nine heave metals(Pb,Cr,Cd,Hg,As,Cu,Zn,Mn and Ni) in crops and soils were determinated by furnace atomic absorption,and evaluating the bioaccumulation of crops.Results The concentrations of nine heave metals in different crops followed the order:cereal>leaf vegetables>non-leaf vegetables.The different corps had different bioaccumulation abilities on the same heave metal.The rate of bioaccumulation Pb,As,Hg,Cr,Zn,Mn,Ni:cereal>leaf vegetables>non-leaf vegetables;Cd:leaf vegetables> cereal >non-leaf vegetables;Cu:cereal> non-leaf vegetables> leaf vegetables.Conclusion The rate of bioaccumulation was different in different crop. |
