“…Heavy metals are released into aquatic systems through wastewater emanating from increased industrial and domestic activities increased concentrations of heavy metals in water bodies, especially rivers and ponds shown adverse effects on aquatic flora and fauna (1). When increasing the level of heavy metals within the plant tissue, the plant either collected the metals in special locations in the root or stem or converts them to other non-toxic forms that may be distributed and used again in the metabolic processes (20). These elements poison depend on their quantity of the object, the absorbed dose and the duration of exposure (34).…”

“…Hydrilla verticillata plant was used in accumulating copper ions were accumulated in the walls of plant tissue cells. (8) studied Hydrilla and Ceratophyllum plants in the laboratory by exposing them to different concentrations (10,20,30,50) as they proved the efficiency of the Hydrilla in the withdrawal and accumulation of heavy metals more than the other plant. Hydrilla plant proved highly efficient to remove (2).…”

The current study was aimed to test the ability of Hydrilla verticillata plant ability to accumulated of cadmium and lead in its tissues. The plant was treated with different concentrations of cadmium (1,2,4,8) ppm and lead (0.5,5,10,20) ppm for 21 days'. The concentration of metals was measured in plant and water, Bioaccumulation factor and removal ratio were also measured during days (1,7,14,21), as well as measured biomass and length of the plant were measured at the end of the experiment. The results were shown that the highest cadmium and lead removal rate were (77, 88) % at concentration (4, 10) ppm during (21, 7) days, respectively, also the bioaccumulation factor (BCF) of the two metals were (21639 and 45467) at concentrations (4 and 0.5) ppm during the 21st day of the experiment respectively. The biomass of plant in treated aquarium with different concentrations of cadmium showed a decrease during the experimental days, while increased in biomass of plant treated aquarium with different concentrations of lead. The length rate of the plant was significantly reduced in the plant that treated with cadmium but significant increase in plant treated with lead compared to the control.
