Phytoremediation of lead-contaminated soils: role of synthetic chelates in lead phytoextraction
Article Abstract:
Chelate-assisted phytoextraction of lead can be a cost-effective approach for soil disinfection. However, the technology can only be economically viable if systems of using high biomass plants that can accumulate more than 1% lead in their shoots can be developed. Along this line, the potential of adding chelates to Pb-contaminated soils to increase Pb accumulation in plants was explored. Results showed that chelates enhanced Pb desorption from soil to soil solution, facilitated Pb transport into the xylem and increased Pb translocation from roots to shoots.
