Abstract:

In recent years, phytoremediation of polluted soil and water resource have gained growing interest. This study address the issue of Cr, Ni, Cu, Zn, Cd and Pb metals accumulation in Fagonia indica and Cenchrus ciliaris native plant species  in the context of their possible use for the sanitation of wastewater of Riyadh city, Saudi Arabia. Represented soil and plant samples were analysed for their total heavy metal concentrations. The results indicated that, Cr and Zn are the most abundant heavy metals in soil samples and the total concentrations of Cd and Pb in soil exceed the average values proposed for common soil. The concentrations of Cr, Zn and Pb metals increased with soil depth, while Ni, Cu and Cd concentrations did not show a systematic pattern. The results indicated that enrichment factor values ranged from 1 to 5. The enrichment factor values for Cr, Ni and Cu elements fall into the normal range while medium enrichments of soil with Zn, Pb and Cd. The accumulation coefficients of the studied  heavy metals in the roots of Fagonia indica and Cenchrus ciliaris plants ranged from 0.71-7.50 and 0.31-2.30, respectively. The order of accumulation coefficients in the roots of of Fagonia indica and Cenchrus ciliaris as follows: Ni > Cu > Zn > Cr > Cd > Fe and Cd > Ni > Cu > Zn > Fe > Cr, respectively. The translocation factors varied between the two plant species and highest for Ni and Cu in both Fagonia indica and Cenchrus ciliaris plants. The highest concentrations were found in roots of Fagonia indica, with 75 mg kg^-1 Ni and 65 mg kg^-1 Cr.
