Utilizzo di piante agrarie nel fitorisanamento di suoli contaminati da metalli pesanti: (i) lo stato dell’arte

Phytoremediation has a strong potential as a natural, solar-energy driven remediation approach for the treatment of soils and sediments polluted. Research has focused several aspects of the process of uptake, translocation and storage of heavy metals in plants. However we can not predict when the technique could find practical application on large scale. Beyond the evaluation of the best suited species, little has been inquired on the multiple aspects of the agronomic management of phytoextraction. This review provides a synthesis of current knowledge on phytoextraction of metals from soils and their accumulation in plants. L’utilizzo di piante per rimuovere elementi inquinanti da suoli e sedimenti, teoricamente ha un potenziale molto elevato soprattutto per i costi di intervento molto contenuti rispetto alle tecniche di bonifica tradizionali e per la sua sostenibilità.
