| Abstract: | In order to explore the accumulative and transferable characteristics of Cd in green herbs,pot tests of Cd bioaccumulation with some herb species,including Ophiopogon japonicus,Eephyranthes candida,Oxalis rubra,Festuca arundinacea,Poa pratensis,Lolium perenne and Trifolium repens,were conducted under the simulated greenhouse conditions.Concentrations of Cd 0 mg/kg,2 mg/kg,4 mg/kg and 20 mg/kg were used in this study,base on the range of Cd concentrations in the soil along a highway.Results showed that plant... |
