EVALUATION OF PHYTOREMEDIATION POTENTIAL OF ROSEMARY PLANT IN CONTAMINATED SOILS WITH CADMIUM AND ZINC

For evaluation of Phytoremediation potential of Rosemary plant in contaminated soils with Cadmium and Zinc, Two Greenhouse pot culture experiments were conducted in Fars Education Center of Jahad-e-Agriculture- Aliabad kamin. Treatments included soil cadmium with six levels (0, 10, 20, 40, 80 and 160 ppm) and zinc with six levels (0, 25, 50, 100, 200 and 400 ppm). Each treatment was replicated three times. In this study, cadmium sulfate and zinc sulfate were used, for contaminate soil samples different amounts of salts dissolved in distilled water and sprayed on the soil. The results showed, with increasing cadmium and zinc concentrations in soil, cadmium and zinc concentration increased in root and shoots. The highest cadmium and zinc transfer factor was observed in treatment 80 and 25 ppm respectively. Maximum bio accumulation factor for cadmium and zinc obtained from 80 and 400 ppm respectively. Rosemary plant can fix the elements of cadmium and zinc and transfer it to the shoot.
