Phytoextraction and fractionation of heavy metals in soil after multiple applications of natural chelants Fitoextração e fracionamento de metais pesados em solo após múltiplas aplicações de ácidos orgânicos

Chelate-assisted phytoextraction of heavy metals is a promising approach to clean up polluted soils. However, the most successful chelants tested so far are synthetic agents that barely degrade in soil, increasing the metal leaching risks. Natural organic acids have been proposed to enhance phytoext...
