PHYTO-REMEDIATION OF LEAD-CONTAMINATED SOIL USING AMARANTHUS CRUENTUS [PDF]

open access: yes
Previous studies have shown that some vegetables have the ability to absorb metals from soil. Since they are early maturity species, they possess the potential to be used as phytoremediating agents. Also, synthetic chelates have been found to induce lead
