Title: Chelate-induced phytoextraction of experimentally metal polluted soil, with Thlaspi Caerulescens

Abstract: Heavy metal contamination of soils has become a serious problem in industrial or agricultural areas. Soils polluted with heavy metals pose a significant health risk to humans as well as plants and animals, often requiring soil remediation practices. Synthetic chelates such as ethylenediaminetetraacetic acid (EDTA) have been shown to enhance phytoextraction of some heavy metals from contaminated soil. In the present study, the effect of EDTA on the uptake of Pb, Zn, Cr and Cu by Thlaspi caerulescens and the toxic effects of EDTA additions on plants were examined. Application of EDTA was effective in accumulation of studied metals in the shoots and decreased metal concentrations in soil.

Key words: phytoextraction, heavy metals, Thlaspi caerulescens, EDTA
