A biological experiment was conducted at 20/1/2011 to 2/6/2011 in pots in the experimental farm of college of Agriculture, 3.5 km south of Arbil governorate, 36˚ 07N, 44˚01E, 0411359, 03997002 UTM. 411m above the sea level, during growing season 2011-2012 in order to determine the effect of different levels of phosphorus (0,10,20,30,and 40 mgkg-1 on heavy metals concentrations and uptake for different parts roots, shoots and grains of wheat plant Triticum durum L. cv.Summit. Soil samples were collected under the polluted location in the landfills were located between Bnaslawa district and Daratoo county, triple super phosphate fertilizer applied to soils to know the effect of phosphorus absorption and distribution of heavy metals in the different parts of wheat plant by using factorial Complete Randomize Design (CRD) with four replicates. The present investigation started at 24/1/2011 and plants were harvested at 2/6/2011. The increase of applied P caused a significant increase (p ≤ 0.05) of the dry matter weight of different parts of plant (roots, shoots and grains) and a significant decrease of heavy metal concentration. A negative correlation coefficient between P and Fe, Ni, Cd and Pb concentrations in roots were (0.98, 0.94, 0.95 and 0.99 and in shoots part 0.69, 0.93, 0.89, and 0.99 and in grains part 0.89, 0.90, 0.97, and 0.96) respectively.
