Abstract
plants grown in contaminated site can expose consumers health to danger, this research was done to evaluate the contamination with heavy metals in part of Diyala River, soil, plants in agricultural lands located on the both side of the Diyala River and irrigated from this river, 12 samples of irrigation water, 12 samples of soil and another 12 samples of plants like celery, radish. malt and clovers were taken and analyzed to find the concentration of some heavy metals Pb, Zn, Ni, Cd, Cr, Mn and Cu, results show that the average concentration of Cd in irrigation water was 0.0215 mg/l and more than the acceptable level for WHO, while the average concentration of Ni in soil was 109.87 mg/kg which is more than WHO limit, on the other hand most of these heavy metals concentration in the surface layer of soil were more than their concentrations in the below layers, this lead to say metals can move and translate through the layers of soil, results for plants show that the average concentration of Pb in all samples was more than WHO limit, it was 1.85, 1.8, 1.375 and 1.04 mg/kg in celery, radish, malt and clovers respectively, therefore the increasing of consumption for this contaminated plants by community could cause health problems in the future.
