Phytoextraction of Cadmium and Lead from Contaminated Soil by Brachiaria Mutica Forsk

Abstract / Excerpt:

A pot experiment was conducted to investigate the phytoextraction of cadmium (Cd) and lead (Pb) by Brachiaria mutica forsk. (para grass) in soil which was initially contaminated with 10,100 and 300 mg/kg of metal. Plants were harvested after three months of planting and analyzed for cadmium and lead accumulation in aboveground shoots and roots. Soil was also analyzed for metal content before and after planting. Results show that the accumulation of both metals in the root was higher than in the aboveground shoot. The accumulation of both metals in all parts of the plant increases as the amount of metals applied to the soil increases. Cadmium was more strongly phytoextraction than lead.
