ABSTRACT
The contamination level of Chromium (Cr), Iron (Fe), Nickel (Ni), Lead (Pb) and Cobalt (Co) was evaluated in the soil samples of agricultural area of the Urmar Bala, district Peshawar, Khyber Pakhtunkhwa, Pakistan. To solubilize the targeted metals from selected soil samples, a wet digestion procedure was adopted. The targeted metals in selected soil samples were in the ranges of: 1.37-2.00, 28.91-29.50, 1.62-1.82, 1.22-1.179 and 0.07-0.112 mg/kg for Cr, Fe, Ni, Pb and Co, respectively. Increasing order of these heavy metals in soil samples were found as: Plum’s farm soil Co < Cr< Ni < Pb < Fe, Peach’s farm soil as Co < Cr < Pb < Ni < Fe, Tomato’s farm soil as Co < Pb < Cr < Ni < Fe, soil of the ridge gourd farmas Co < Pb < Cr = Ni < Fe, soil of the lady fingers farm as Co < Pb < Ni < Cr < Fe while soil of the wheat farm was found in the order of Co < Cr < Pb < Ni < Fe. The concentration of Fe in all soil sample was found in the maximum ranges while those of Co in the minimum ranges.
