Phytoremediation Efficiency of Sorghum bicolor (L.) Moench in Removing Cadmium, Lead and Arsenic

Heavy metals are a significant problem in municipal wastewater, in soil accumulation and are costly to remove in order to facilitate water use in irrigation. Wastewater, with three heavy metal cations and an iron, was employed in irrigation during the Sorghum bicolor (L) Moench growth period. Results show that the absorption coefficient or bioaccumulation ability of Sorghum bicolor (L) Moench is relegated to certain heavy metals and their concentrations, but not at all to plant tissues in dry ash weight (DAW) scale.
