*2.3.2 Phytovolatilization*

Phytovolatilization involves the uptake of contaminants by plant roots and its conversion to a gaseous state, and release into the atmosphere. This process is driven by the evapotranspiration of plants [47]. Metals are absorbed into volatile organic compounds during phytovolatilization, and these compounds are then released as biomolecules into the environment [48]. Succulent plants are regarded as a choice of plants in mining areas in arid and semi-arid environments.
