In this study estimation some heavy metals (Fe, Ni, and Co) in soil and Phragmites australis plant in Fatha and Qayyarah areas in Salah Al-Din Governorate- Iraq. The results indicated the mean concentration of heavy metals was high in the far soils from Phragmites australis, reaching (515.2277, 567.406) µg/g in Qayyarah and Al-Fatah sites, respectively, compared to the nearby soils from Phragmites australis, reaching (486.5935, 547.0155) µg/g in the Qayyarah and Al-Fatah sites, respectively. The mean concentration of heavy metals in the roots compared to the leaves was (263.1625, 447.4625) µg/g in the roots of the Phragmites australis for Qayyarah and Al-Fatah sites, respectively, and it reached (150.6750, 266.5346) µg/g in the leaves of the Phragmites australis in Qayyarah and Al-Fatah sites, respectively.
The Phragmites australis showed bioaccumulation of heavy metals in its roots higher than the rest of the plant, and the copper (Cu) element in the Al-Fatah site was superior to the rest of the heavy elements (Fe, Ni, and Co) with a bioaccumulation rate of 2.325 µg/g and the cobalt (Co) element on the rest of the heavy metals in Qayyarah have a bioaccumulation rate of 2.835 µg.
