Abstract:
Taking wutacai (‘Jinmudan’),Brassica oleracea(‘Shanghaiqing’) and pakchoi (‘Four Season Cream Pakchoi’) as test materials，the root-shoot transport coefficients (i.e.TF) of medium (i.e.TF-Ca and TF-Mg) and trace elements (i.e.TF-Fe，TF-Mn，TF-Cu and TF-Zn) under single Cd，single As and Cd-As combined pollution were analyzed,in order to provide reference for heavy metal pollution control and safe vegetable production.The results showed that the TF-Ca，TF-Mg，TF-Fe，TF-Mn，TF-Cu，TF-Zn in different leafy vegetables were affected differently by heavy metal treatment.TF-Ca，TF-Mg and TF-Zn of wutacai and Brassica oleracea increased under different heavy metal treatments.Under different treatments，TF-Fe of the 3 leafy vegetables and TF-Cu of wutacai decreased.As for TF-Mn，the 3 leafy vegetables was not affected by single Cd treatment，while wutacai and pakchoi had an increasing trend under both single As and Cd-As combined pollution.Except for Mn and Fe，there was no significant correlation between TF of heavy metals and TF of mineral elements in leafy vegetables.
