Title: | Chelate-assisted phytoextraction: Effect of EDTA and EDDS on copper uptake by Brassica napus L | Authors: | Zeremski-Škorić T. Sekulić P. Maksimović, Ivana Šeremešić S. Ninkov J. Milić S. Vasin J. |
Issue Date: | 1-Nov-2010 | Journal: | Journal of the Serbian Chemical Society | Abstract: | Chelate-assisted phytoextraction is proposed as an effective approach for the removal of heavy metals from contaminated soil through the use of high biomass plants. The aim of the present study was to compare the efficiency of the two chelators: EDTA and biodegradable EDDS in enhancing Cu uptake and translocation by Brassica napus L. grown on moderately contaminated soil and treated with increasing concentrations of EDTA or EDDS. Increasing amounts of EDDS caused serious growth suppression of B. napus and an increase in shoot metal concentrations. Growth suppression limited the actual amount of phytoextracted Cu at high concentrations of EDDS. The maximum amount of extracted Cu was achieved by the application of 8.0 and 4.0+4.0 mmol kg -1 EDDS. The shoot Cu concentrations after EDTA application were much lower than with EDDS at the same doses. According to these experiments, EDTA does not appear to be an efficient amendment if Cu phytoextraction with B. napus is considered but EDDS is. 2010 Copyright (CC) SCS. | URI: | https://open.uns.ac.rs/handle/123456789/11020 | ISSN: | 03525139 | DOI: | 10.2298/JSC091207086Z |
