This study was done to recognize the capacity of C. demersum for different concentrations of lead element in lab aqueous ecosystem. The concentrations of 10, 20 and 30 ppm were used in three replications for each concentration for 30 days. The results showed that the plant can remove 30 ppm of Pb. Significant differences were found in removing capacity by plant for Pb, in all concentrations 10, 20, 30 during experiment period. There was accumulation in the stem more than the leaf. The highest removal ratio for Pb in the stem was 10.25 ppm, 9.18 ppm in the leaf and the lowest removal ratio was 8.01ppm in the concentration 30 ppm for 30 days. | Phytoremediation of lead by ceratophyllum demersum Lab. work
