In the soil water, a fraction of these contaminants can be biodegraded, particularly in the rhizosphere, where the process is enhanced by root exudates. Another fraction can be uptaken by plants and translocated by xylem. Once incorporated in the plant, a fraction of the incorporated contaminant is metabolized, while the rest remains unaltered. Three stages can be distinguished in the metabolization process: (1) oxidation, (2) conjugation, and (3) accumulation in the vacuole or cell wall.
