The following points highlight the five mechanisms of metal phytoremediation by plants. The mechanisms are: 1. Phytoextraction 2. Phytostabilization 3. Rhizofiltration 4. Phytovolatization 5. Phytodegradation. Mechanism # 1. Phytoextraction: This approach is primarily used for the treatment of contaminated soils. This process uses plants to absorb, concentrate, and precipitate toxic metal from contaminate soil and […]
