ESTIMATION OF SOME HEAVY METALS IN SOIL AND Phragmites australis (PHYTOREMEDIATION) IN FATHA AND

In this study, heavy metals (Fe, Ni, and Co) were measured in soil and Phragmites australis plants in the Fatha and Qayyarah areas of the Salah Al-Din Governorate in Iraq. The results showed that the mean concentration of heavy metals in soils far from Phragmites australis was high, reaching (515.2277, 567.406) g/g in Qayyarah and Al-Fatah sites, respectively, compared to nearby soils from Phragmites australis, which reached (486.5935, 547.0155) g/g in Qayyarah and Al-Fatah sites, respectively. The mean heavy metal concentration in the roots compared to the leaves was (263.1625, 447.4625) g/g in the roots of Phragmites australis for Qayyarah and Al-Fatah sites, respectively, and it was (150.6750, 266.5346) g/g in the leaves of Phragmites australis for Qayyarah and Al-Fatah sites, respectively.

The bioaccumulation of heavy metals in the roots of Phragmites australis was higher than in 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 g/g, and the cobalt (Co) element in Qayyarah was superior to the rest of the heavy metals with a bioaccumulation rate of.
