Chelate-assisted phytoextraction of lead using : laboratory vs. field experiments.

The development of more sustainable remediation techniques has been receiving greater attention, as an alternative to soil excavation plan in urban gardens. An phytoextraction experiment with buckwheat ( was performed with a 5mmol kg citric acid (CA) application. Joint experiments under laboratory conditions were conducted using various cultivars of in two soils with a Pb contamination of either geogenic or anthropogenic origin and various chelate concentrations.
