The term "Green Liver" refers to the concept of using plants to detoxify and transform environmental pollutants, much like a liver detoxifies and processes toxins in an organism. In the context of phytotransformation, it involves the ability of plants to absorb, metabolize, and degrade contaminants from the soil, water, or air. This process can involve various mechanisms such as uptake, accumulation, and enzymatic breakdown of pollutants. The idea is that plants can serve as natural purifiers, reducing the concentration of harmful substances in the environment, thus acting as a "green liver" for ecological systems.
