Pollution of heavy metals in soils are main environmental complications, it is necessary to find an effective and economic soil remediation methods. The currentresearch was conducted to investigate the remediation of heavy metals (HMs) as cadmium in different concentrations (100, 150 mg Cdkg-1 soil, Cd100, Cd150) and lead (600,1000 mg Pb kg-1 soil, Pb600, Pb1000) or mixture of both metals (Cd100/Pb600) polluted soils (clay and sandy loam) by activated carbons (ACs)from quinoa stalks (QC), rice straws (RC ) and corn stalks (CC)at two doses (1% and 2%, w/w).The polluted soils were incubated with ACs for 0, 1,7,14, 30 and 60 days at 25 °C to evaluatethe effect of ACs addition on metals distribution in fractions, mobility in soils, availability and plant uptake. Results indicated that addition of ACs to soils significantly increased pH and organic matter (OM) but decreased Cd and Pb availability in soils and plant uptake comparing to control soils. Cd was mainly increased in carbonate fraction (F3) but Pb incorporated in the residual fraction (F6).Furthermore, the addition of ACs diminished the solubility of Cd and Pb in terms of water soluble (F1) andexchangeable (F2).This finding provides evidence that remediation of HMspolluted soils by ACs decreased Cd and Pb toxicity by immobilizing theminto more stable forms and improved soil quality. The results indicated that AC decreased Cd and Pb in soils and their uptake by spinach plants compared to control.The use of ACs can be precisely, economically, time-effectively, and efficiently to remediate Cd and Pb pollutedsoils. Activated carbon from QC was the most effective ACs to decrease Cd and Pbavailability particularly in clay soil compared to RC and CC (in polluted soils).
