Abstract: Effects of 3 industrial activities on the concentrations of toxic metals (Cd, Cr, Ni and Pb) and micro-nutrients elements (Fe, Cu, Zn and Mn) in the leaves of 2 and 4 years old Ziziphus trees grown closed to these industrial areas were studied during March 2013. The highest Cd, Cr, Ni and Pb concentrations in the Ziziphus leaves were found in the trees closed the paints, chemical and paper industrial sectors with values of 4.56, 8.69, 6.15 and 48.47 mg/kg, respectively, while the trees in the control area had 1.09, 1.16, 1.34 and 6.27 mg/kg, respectively. The sector of mineralization, plastic and building materials was the highest in Fe, Cu, Zn and Mn emission pollutants accumulated and absorped by the tree leaves. The 4-years old tree leaves were significantly higher than the 2-years old tree in all studied toxic and micro-nutrients elements.
