Assisted phytoremedia for the remediation of polluted land

Share:

The biologists and biochemists of the Research Center for Renewable Energies and the Environment are identifying the optimal conditions for applying assisted phytoremediation to areas contaminated by heavy metals and hydrocarbons.
The research is conducted in the Environmental Technologies unit of the Research Center for Renewable Energies and the Environment in collaboration with the Institute for the Study of Ecosystems of the CNR of Pisa on behalf of Syndial, the company of the Eni group that deals with rehabilitation environmental.
Among the in situ remediation technologies available today, phytoremediation (phytoremediation) exploits the natural purifying ability of plants to extract both heavy metals and organic compounds from the soil.
The process improves the physical and chemical characteristics of the land to achieve real environmental and landscape redevelopment. The main mechanisms are two: on the one hand, the plants extract heavy metals from the soil and accumulate them in the roots and leaves (phytoextraction); on the other, by exploiting the synergy between plants and micro-organisms present around and within their roots (rhizospheric microorganisms), biodegradation (phytorizodegradation) of organic contaminants is promoted in other simpler and less toxic substances entering the food chain of the organisms present in the soil. When the action of the plants is supported by particular growth-promoting bacteria (Plant Growth Promoting Rhyzobacteria) we speak of assisted phytoremediation (enhanced phytoremediation).
