According to Tables 4, It was clear that the concentration of extractable Pb significantly decreased in
the planted soil after 60 days culture. It was clear that the concentration of extractable Lead in soil under all
treatments dercreased between 39.2-40.9%.
Accumulation of Pb in root is higher than in shoot, this showed that root of Corn is more active than
shoot to phytoremediation of Lead. This is in line with findings of Parsadoost et al. (2008) and Cho-Ruk
(2006).
