PHYTOREMEDIATION AIDED BY AMENDMENTS AND PHYTOSTABILIZATION OF POTENTIALLY TOXIC ELEMENTS

Abstract

Natural processes, such as natural remediation or natural attenuation to control contamination with potentially toxic elements (PTE), can take very long time (years) to achieve a state of equilibrium. In general, soils polluted with PTE have physical, chemical and biological limitations for establishment and development of plants. However, man aided remediation reduces the soil recuperation period. An alternative to help in this process consists in adding amendments and reintroducing symbiotic microorganisms that are beneficial for plants. This alternative is known as aided phytoremediation or induced phytoremediation. In this study, amendments management practices with possible high positive impact on phytoremediation are summarized.
