Phytovolatilization

Plants remove inorganic contaminants· either by contaminant volatilization or by metal accumulation.

Volatalization is useful for the removal of mercury. A bacterial mercuric ion reductase has been transferred to Arabidopsis thaliana; this transgenic plant absorbs mercury, and reduces it to volatile Hg0, which volatilizes from the leaf surface.
