Abstract

The aim of present study was to investigate PHYTOREMEDIATION potential of Puccinellia distans (Jacq) Parl using EDTA and DTPA and identify method of decreasing Cd- chelating leacing risk. The soil samples spiked with CdCl2. The treatments comprised the following dosages 2.5DTPA, 5DTPA, 2.5EDTA, 5EDTA, 2.5EDTA+ 2.5DTPA, 2.5EDTA+5DTPA, 5EDTA+2.5DTPA, 5EDTA+5DTPA and control pots were not treated with EDTA and DTP A. Bioconcentration factor (BCF), translocation factor (TF) and TOLERANCE INDEX (TI) were calculated to deter mine the Cd PHYTOREMEDIATION efficiency. Results indicated that EDT A and DTP A application significantly increased Cd content in the plant tissues and root concentration of Cd was greater than the concentration in the shoot. The maximum bioconcentration factors (BCF) were observed in 5DTP A and 5EDT A, respectively, and the maximum translocation factor (TF) was obtained for 5EDTA+5DTPA treatment. The results indicated that EDTA and DTPA had the potential to promote the uptake of Cd by P. distans. In the next step, to reduce leaching of Cd-chelate, 5mg kg-1 EDT A and DTPA in three methods of single, triple and six successive dosages were added to the soil. The results indicated that under sing le application, Cd con tent reached at its minimum concentration in the soil and in the plant organs, the Cd concentration was the maximum. Metal concentration in the plant organs did not vary significant when triple and six successive dosage were added (P<5%). Overall, optimum phy to extraction of P. distans and Cd leaching reduction into ground waters was achieved when 5mg kg-1 EDTA and DTPA was added in single dosage.
