The limited efficacy and high cost of conventional physical-chemical treatments used in the rehabilitation of soils affected by pollutants, which in many cases irreversibly affect the properties of the soil, water and living beings that inhabit them, have stimulated the development of new technologies.
Phytoremediation takes advantage of the plants ability to absorb, accumulate, metabolize, stabilize or volatilize organic and/or inorganic contaminants present in the soil, air or water, together with the complex interactions they establish with the rhizosphere, give this technology, Important advantages over other conventional methods of remediation of pollution, among which stands out a lower economic cost, a more respectful approach with the ecological processes of the edaphic ecosystem, and the fact that it is a more accepted social, aesthetic and environmental technology.
