Abstract: Contents of 4 common metal elements(K,Na,Ca and Mg),18 trace metal elements(V,Ba,Sr,Be,Bi,Ti,Sn,Li,Nb,Zr,Ga,Th,Sc,La,Sb,Ni,Ce and Y) and 10 heavy metal elements(Cu,Pb,Zn,Cd,Cr,Co,Ni,Fe,Mn and Mo) in five soilless cultivated vegetables were analyzed for comparison with unpolluted terrestrial vegetables so as to evaluate food safety of the soilless cultivated vegetables.For all the five soilless cultivated vegetables of the polluted water,enrichment level of metal elements was found different.Their average enrichment coefficients of common metal elements were(2-150) times.Their average accumulation of trace metal elements was higher than in the unpolluted terrestrial vegetables.And their enrichment coefficients of heavy metal elements were mostly 10 times.No significant difference was found between the soilless cultivated vegetables and the terristrial vegetables in heavy metal accumulation.Contents of heavy metals in all treated and non-treated vegetables are lower than the national standards for food safety.
