Phytoremediation is an eco-friendly and low cost potential strategy for cleaning up of heavy metals from contaminated soils. Selection of promising plant is an important approach for successful phytoremediation. In two separate pot culture experiments, five levels of soil cadmium (Cd) concentrations as 15, 30, 60, 120 and 240 mg Cd kg soil and five levels of lead (Pb) including 500, 1000, 2000,...

Selenium (Se) in irrigation drainage water became a major concern after it was implicated in deaths and deformities of waterfowl at Kesterson Reservoir (Presser and Ohlendorf 1987; Ohlendorf 1989). Subsequently, other areas with irrigationinduced Se problems (or potential problems) have been identified in several western U.S. states (Seiler 1995), reinforcing the status of Se as a U.S. Environm...

This review presents the justification of research into heavy metals and clean-up technologies with particular emphasis on phytoremediation of heavy metals contaminated soils. The generating sectors and heavy metal contaminant contributors are reviewed alongside likely types. The new paradigm by researchers in response to negative impacts of various clean-up methodologies has been discussed. Th...

The potential of perennial bioenergy Miscanthus feedstock grown on heavy metal contaminated land was evaluated for the production clean renewable energy, chemicals, and recovered metals. Trace element analysis showed significant levels contaminants from harvested Miscanthus: 6.47 g Pb per kg biomass, 1.91 kg−1 Fe, 0.35 Zn, 26.59 mg Cu; along with other metals including Cr, Ni, As Cd. protic ion...

In this study, we report phytoremediation of textile dyes using hairy roots derived through Agrobacterium rhizogenes (NCIM 5140) infection of in vitro leaf and stem explants of a halophyte Sesuvium portulacastrum (L.) L. Leaf explants showed higher frequency of hairy root induction (70%) than stem explants (30%), and maximum number of roots (leaf 42.3 ± 2.4 and stem 50.3 ± 1.7). Transformed nat...
