Abstract
Pollution of the biosphere with toxic metals has increased dramatically since the beginning of industrial revolution. The sources of lead (Pb) contamination include metal smelting, Pb based paints, lead arsenate, pesticide and phosphate fertilizers (Singh et al., 1997). Another major source is Pb alkyl derivatives in gasoline which are cracked to release Pb in automobile exhaust in the form of lead aerosols. Recently Pb was found to be a major contaminant of ponds (Chandra et al., 1993) and lakes (Tripathi et al., 1997). Plants have been used to decontaminate Pb from contaminated environment (Gupta & Chandra, 1994; Gupta et al., 1995; Rai et al., 1995a; Boyajian & Carreira, 1997).
