The regeneration of contaminated areas, carried out
by human activities, can be conducted by several methods
including phytoremediation, which features the reduction of
levels of contaminants from soil and water and keeps consistent
safe levels for protection of human health by preventing the
dissemination of environmentally hazardous substances.
Among the phytoremediation techniques, phytoextraction is
one of them from which the plant assimilates the pollutant,
and afterwards deposits it in the plant tissue, which favors
the disposal of material that can be either ignited and used in
co-processing or destined to a landfill (Andrade et al., 2007).
