The paper presents the results of a study on the heavy metals in some green leafy vegetable .The leafy vegetable was sampled from different areas of Sulaimani city . The vegetables were digested using three- acid mixture (68%HNO3,98%H2SO4 and 37%HCL). Analyzing of the heavy metals was performed using atom absorption spectrophotometry . The concentrations (mg/kg) of the heavy metals in samples were ranged from (6.118 to 339.646 for Fe , 0.032 to 0.247 for Cr , 0.0003 to 0.022 for Cd, 0.196 to 0.357 for Cu, 0.037 to 0.503 for Ni and 0.690 to 2.941 for Zn. The highest concentration of heavy metals was for Pb in leek and Fe curly cress at the Garazel.The amount of Cu in mint, leek , dill and celery in the samples collected from wuluba farms more than those of Garazel farms .In contrast the amount of Ni in mint , leek , dill and celery in the sample collected from Garazel farms more than those Wuluba farms. So , The amount of Pb in dill, celery,curly cress and Cd in mint,leek,dill in the sample collected from Wuluba farm more than those of Garazel farms. However, the amount of Zn in mint, celery and curly cress in the sample collected from Wuluba farm more than those of Garazel farms. Also, the amount Fe in mint, dill,celery , curly cress and Cr in celery , curly cress in the sample collected from Garazel farm more than those of Wuluba farms. It can be concluded from this investigation that the amount of Pb,Fe,Cr,Cd,Cu,Ni and Zn were lower than the acceptable level recommended by WHO,FAO.
