Vegetables with trace elements are necessary for human body, therefore these element are needed to be supplied continually for daily life. In this report three element of Cd, Pb and Co were isolated from stem and leaf of spinach and Celery vegetables, and from the soil of Ghazvin and Khoramabad cities In Iran. The characterization was done by Atomic Absorption; by comparing the results, it shows that absorption strength for Cd, Co and Pb elements from soil in Celery vegetable is lower than in Spinach vegetable. The air pollution has no effect in absorbing the elements Cd, Co and Pb by Celery vegetable but, it has been observed that air pollution has some effect for absorption of Cd, CO and Pb by Spinach vegetable In Ghazvin Industrial city. The concentration of elements Pb, Cd and Co in Spinach leaf vegetable higher than Spinach stems vegetable and also concentration of elements Pb, Cd and Co in Celery stems vegetable higher than Celery leaf vegetable.
