Heavy metals may have deleterious effects on soil§microorganisms and plants. Excess of zinc, cadmium§and lead in soils have been linked to human health§effects, animal fatalities and the disruption of§natural ecosystems. At present, the most common clean§up technology consists of removing contaminated soil,§transporting, the soil to landfills and replacing the§soil with clean topsoil. This clean up technique does§not solve the problem; it only transfers problem soil§from one area to another in a relatively costly and§cumbersome way. Hence, the use of highly specialized§plants, which are able to accumulate high§concentrations of heavy metals in harvestable shoot§tissue, termed phytoremediation involves successive§cropping of these plants on contaminated sites. This§monograph is focus on phytoremediation as a novel§strategy for the removal of toxic metals from the§environment using plants.
