The maximum contents of Cu, Cd, Zn and Pb were found in salad samples taken from the intensively irrigated fields and Ni in a salad sample from a moderately irrigated field, suggesting that the irrigation with polluted waterled to accumulation of heavy metals in plants. The TF was of the order Cd > Zn > Cu > Ni > Pb.SPATIAL DISTRIBUTION AND POLLUTIONOFHEAVY METAare to assess the copper (Cu), zinc (Zn) and lead (Pb) concentrations and to determine the contamination ofheavy metal with contamination factor and goo accumulation index (lgeo).
