Phytoremediation is a common form of bioremediation that employs plants to extract/remove toxic pollutants . The main biological mechanisms of phytoremediation observed for heavy metal extraction are through uptake and deposition into biological mass in the plant root system (rhizofiltration) Furthermore, subsequent translocation of toxic metals to accumulate in the shoot system may occur, a process also referred to as phytoextraction . Tolerant plants are, therefore, useful in cleansing and phytostabilising affected surroundings by sequestering toxic cations .
