Phytovolatilization involves:
Phytovolatilization constitutes specialized phytoremediation pathway where selected plants absorb contaminants that are volatile in their native form or can be enzymatically transformed into volatile derivatives, translocate upward via xylem driven by transpiration pull generating negative pressure minus 1 to 2 MPa, and release through stomatal conductance into atmosphere as less toxic gaseous species. Classic illustrations include selenium taken up as selenate via sulfate transporters Sultr in Brassica juncea, metabolized through cysteine synthase to selenocysteine, methylated by selenocystei
