Multielement concentrations in vegetable species grown in two typical agricultural areas of Greece

The multielement (As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, V, Zn) levels in various common vegetables and surface soils collected from two typical growing areas of north-western Greece are presented. The results are representative and indicate metal concentration levels in vegetables grown in Creek areas under similar conditions. The content of the metals is generally at the same levels or even lower than that reported for vegetables consumed in several countries and species grown in other agricultural and industrial Greek areas. Enhanced levels of metals observed in certain vegetable species could be related to their concentration in the corresponding soils. The results of the present study indicate that the mean intake of heavy metals (As, Cd, Pb and Se) by adults due to consumption of vegetables from the two sites, for an average consumption pattern, generally is well below the allowable daily intakes. On the other hand, the contribution of the vegetables to the recommended amounts of the essential elements (Cu, Fe, Mn and Zn) is satisfactory and higher than previously reported.
