Abstract
The effects of increasing concentrations of lead chloride on growth characteristics of Trapa natans including root length, leaf area and biomass production was studied. Estimation of bio concentration factor is very much important. It indicates that the species is more favorable to tolerate higher concentrations of heavy metals and also helps a lot in decontamination of the land, water etc. To understand the effects of heavy metals upon plants and the resistance mechanisms, would make it possible to use plants for cleaning and remediating heavy metal polluted sites. In this study increasing concentration of lead showed higher accumulation capacities and may be better treatment option for lead by means of phytoremediation. Trapa natans have great potential to accumulate heavy metals and can be effectively used in phytoremediation. The present study also reveals that Trapa natans can be effectively used to cleanup aquatic ecosystems.
