Název v původním jazyce

Chemically induced phytoextraction of lead from smelter-impacted agricultural soils

Popis výsledku v původním jazyce

Chelant-enhanced phytoextraction of heavy metals is an emerging technological approach for a non-destructive remediation of contaminated soils. The main objectives of this study were (i) to assess the extraction efficiency of two different synthetic chelating agents (EDTA, EDDS) used for desorbing Pb from two studied multi-metal contaminated agricultural soils originating from a mining and smelting district and (ii) to assess the phytoextraction ability of maize (Zea mays) and poplar (Populus sp.) afterthe chelant application. EDTA was more efficient in desorbing and complexing Pb from both soils compared to EDDS, removing as much as 60% of Pb from soil. The PHREEQC-2 thermodynamic modeling showed that the majority of Pb is present as &#61531;Pb-EDTA&#61533;2- complexes (> 99%) after the EDTA application. Maize exhibited better results than poplar in Pb uptake from a more acidic (pH ~ 3-4) and more contaminated (up to 1360 mg Pb kg-1) agricultural soil originating from the smelting ar
