Abstract
Lead is an element of considerable environmental and toxicological interest because of its potential deleterious effects upon human health. In this research, a laboratory-constructed hydroponic system was employed to characterize bioremoval of lead by a submerged, rootless aquatic plant, Ceratophyllum demersum L. (Coontail or hornwort). Three concentrations of lead were used (0.125, 0.250, and 0.500 μg/ml). Results indicated that maximum lead removal of 65.6%, 58.2% and 56.4% were achieved from nutrient media with low, medium and high initial concentrations, respectively, after 25 days. Generally, lead uptake (absorbed fraction) increases with time till reaching equilibrium at the last five days of the experiment. The highest lead uptake rate was recorded in the first five days in all treatments. On the other hand, the adsorbed (exchangeable) fraction of lead onto C. demersum showed a remarkable decrease with increasing metal concentration in the nutrient media. Results also showed that C. demersum can accumulate and adsorb high amount of lead in concentration and duration dependent manner. This research indicated the remarkable bioremoval potentialities of C. demersum as it is capable to remove 32.2% of the lead under relatively high concentration (0.500 μg/ml) within five days. Accordingly, this plant can be useful for the design of cost effective and eco-friendly wastewater treatment plants.
