Three radish cultivars  namely Ufasic,  Gigante,  and Saxa2  grown under plastic house, irrigated by familiar Life drinking water, well and Dohuk river wastewater to evaluate the risk of accumulated  heavy metals in leaves and root of three radish cultivars. The obtained results manifested that a very high amount of Pb accumulate as compared to the international recommended standard. Maximum Pb limit for human health has been established for edible parts of crops (0.2 mg.kg^-1). Particularly, in edible leaves of radish irrigated with bottled water “life” and waste water (19.8641 and 15.6603µg.g^-1,respectively).Similar trends obsered in accumulated Pb in edible  roots of life water (19.69µg.g^-1) and waster water (25.74µg.g^-1).Waste water  significantly increased  the accumulated Zn (9.732µg.g^-1 ), in edibile leaves of radish. Radish roots were not capable to sequestered Zn in their roots, and therefore, most absorbed Zn  translocated to leaves. The  lowst  accumulated Cd in  edible  radish  root (0.986µg.g^-1) observed in radish irrigated with well water. Saxa2 can be recommended for Pb bio remedy for extracting Pb from growing media. Ufasic and Saxa2 can be recommended for Zn extraction from growing media. Gigante engages the gap between them. Interaction results mentioned in results and discussion.
