Abstract :
    In this study, Transfer factor (TF) of strontium ion to Radish and Cress was investigated in the soil of Tehran suburb polluted artificially. The TFs were the ratio of the concentrations of the strontium ion in crops to those in soil, both as dry weight (ppm). In order to investigate the effect of pH and the concentrations of the strontium ion on transfer factor, Radish and Cress were grown in the soil polluted artificially with concentration of 50, 200, 500, and 1000 mg/kg of strontium aqueous solution and at two pH levels 5 and 6. The samples were analyzed by ICP-OES device. The results showed that by increasing of strontium concentration in soil, the amount of absorption of this element by plants was increased and the transfer factor was decreased. Also in the soil with lower pH, higher absorption and transfer factor was reported by the plants. Comparing transfer factor and absorbed strontium between two plants showed that Radish absorbed higher strontium and had a higher transfer factor. Also Comparing between radish leaf and radish root showed that radish leaf absorbed higher strontium and had a higher transfer factor.
