Studies On The Blastofiltration Potentials Of Selected Plant Seeds For The Treatment Of Lead And Cadmium Contaminated Water Samples

ABSTRACT Phytoremediation, based on the theory of botanic tolerance and accumulation of certain pollutant, is a new developing ecological technique primarily used to clean polluted environment. Blastofiltration is applied to phytoremediation of heavy metal polluted water at present. The study used castor, okra, melon and moringa seeds as experimental materials to investigate their potentials as possible blastofiltration materials. The results showed that with the trial time lasting up to 72 hours, lead (Pb) and cadmium (Cd) content in the contaminated water (60ppm in each case) decreased by 9…
