چکیده

in recent decades, phytoremediation is one of the methods which has been a lot of attention. in this process by using of green plants can be removing or eliminate pollutants from water, soil and sediments. therefore, to achievement the objective, this experiment was done in pot culture using completely randomized design with different levels of cadmium concentrations (cdcl2.h2o) including 0, 5, 50, 100 mg kg-1 and also chromium concentrations (crcl3): 0, 50, 100, 150 mg kg-1 with three replications. spinacia oleracea was used to remove or reduce the concentration of cadmium and chromium. metals were determined by acid digestion method and atomic absorption set. results were analyzed with spss (version 16) and macro software. tables and graphs were traced with excel software. results indicated that cadmium and chromium concentration in shoot significantly affected by their concentration in soil (p

Phytoremediation is one of the cleanup methods of polluted soil that is possible accumulation of heavy metals in plant tissues, exclusion of these elements from contaminated soil. Therefore, to achievement the objective, this research was done in pot culture using completely randomized design at the University of Birjand in 2011. Two species Spinacia oleracea and Lepidium sativum were used to r...

Bioremediation potential of spinach (Spinacia oleracea L.) for decontamination of cadmium in soil

Greenhouse pot culture studies were conducted to evaluate the bioremediation potential of spinach for removal of cadmium. The results indicated that spinach was able to take up cadmium in substantial quantity in the shoot. There were no visual cadmium toxicity effects on spinach and no significant reduction in the dry matter yield up to 20 μg g cadmium. Significant growth retardation of fenugre...
