This research was done to compare Pb accumulation in Myrtus communis and Pinus brutia in different concentration (0, 200, 500 and 1000). Results showed Pb accumulation in root and leave of Olea europaea increased with increasing Pb concentration. The highest Pb accumulation in root of Olea europaea in concentration of 1000 was equal to 101 mg/kg, that of this only 38 mg/kg (37.6 percent) transferd to leaves. The highest Pb accumulation in root of Thuja orientalis in concentration of 500 mg/kg was equal to 235 mg/kg, that of this only 30 mg/kg (12.5 percent) transferd to leaves.. proline significantly increased in Thuja orientalis in Pb concentration of 500 and 1000 mg/kg. Proline and soluble sugar increased in Olea europaea only in Pb concentration of 200 mg/kg. Sugar soluble increased in Thuja orientalis only in Pb concentration of 500 mg/kg. The solouble sugar increased with increasing Pb concentration in Thuja orientalis and the highest sugar was measured in 500 mg/l. For determining the maximum Pb adsorbed with soil, Langmuier isothermal adsorption equation constants were calculated. The result detects, Maximum Pb adsorbed by soil is at about 1000 mg/kg. It is concluded that under condition of this experiment both plants are able to grow in Pb-contaminated soil and Thuja orientalis did better work.
