Descripción
Remediation of abandoned mine sites is a real challenge. Phytoremediation, the use of plants to extract contaminants, is an attractive solution since it does not imply costly technology and only requires common agricultural practices. The only handicap is the slow growth rate and low biomass production. Metals in abandoned mine soils become more stabilized with time, being strongly bonded to soil solids. In order to increase bioavailability of metals in soils, we used humic acids extracted from leonardite. Hyperaccumulator plants usually accumulate only one or two specific elements and are thus not applicable to extract multiple elements. Researchers have suggested that a plant used for phytoremediation should be fast growing, deep-rooted, easily propagated and have a high biomass production. Vetiveria zizanioides has proven to be tolerant to high concentration of metals and has very deep roots. The objective of this research was to investigate the use of humic acids from leonardite as chelators in assisted phytoextraction, using vetiveria zizanioides as the extractante plant. Results showed that each dosis of humic acids was suited for releasing different metals from the soil matrix and making them available for plant uptake.
