“…This agreed with the results of a study by Jelusic et al (2013) in which B. bara cultivated in EDTAÀwashed soils accumulated more Pb and Cd in its upper parts. Accumulation of PTEs in the leaves of B. bara and L. sativa could be explained by a higher internal translocation of Cd and Pb from roots to shoots for the plants cultivated in the washed soils compared with the untreated soils (Lestan, 2015). It has been indicative of that enhanced plant uptake of metalÀchelator complexes could transpire in points at which suberization of the root cell walls has not yet developed and at breaks in the Casparian strip and the root endodermis (Nowack et al, 2006;Jelusic et al, 2013).…”

“…However, Pb could be transported to shoots as PbÀchelator complexes when EDTA is present in soil (Luo et al, 2018), increasing the Pb concentration in the aboveground parts and decreasing it in the roots. Cd is more accessible than Pb to plants and is more mobile than Pb and less mobile than Zn (Jelusic et al, 2014a;Lestan, 2015;Komínkov a et al, 2018), which is an essential element for plants. Cd shares transport pathways with Zn in plants (Pence et al, 2000).…”

Copper compounds in the form of fungicides are most commonly used as a measure of protection against vine diseases. Typically, around a dozen treatments are done throughout a year with a dispersion of approximately 5–10 kg of Cu per hectare. For many years, the remediation of heavy metals has often involved the use of ex-situ soil washing with chelating reagents. Amino acids have a lower metal chelation capability compared to EDTA and its derivatives, but they have numerous other advantages in comparison. The main goal of this research was to investigate the ability of 9 amino acids and one dipeptide to extract Cu from various vineyard soil samples and compare their chelating ability with other 'green' chelating agents. The average content of Cu extracted with amino acids is 34.7 ± 16.7 mg/kg or 30.3 ± 5.43 wt.% relative to the pseudo-total content. This is more than what was extracted with carboxylic acid salts (9.91 ± 7.49 mg/kg or 8.45 ± 5.56 wt.%) but less than with EDTA (98.5 ± 42.7 mg/kg or 79.9 ± 7.12 wt.%). The descending order of tested amino acids relative to the removed Cu (mg/kg) is: His > Ser > Thr > Leu > Gly > Val > Phe > Gly-Gly ~ Ala > Arg. The results of this paper show that the amino acid structure is the most important factor for efficient Cu extraction, while the physicochemical properties of the vineyard soil have less impact.

“…Thus, soil remediation is necessary to attain more acceptable environmental conditions [8]. In this concern, ethylene di amine tetra acetic acid (EDTA) forms water-soluble complexes with heavy metals in soil [9,10] and therefore is considered an efficient soil-washing liquid for extracting these metals from soils [11,12]. This amendment can also be used for inducing phytoextraction of heavy metals [13] and probably metalloids from polluted soils by grown plants [14].…”

Although EDTA solution is considered an efficient soil washing liquid for extraction of heavy metals from soils, its low biodegradability may alter soil properties and suppress plant growth. Alternatively, chlorides are safer and cheaper washing liquids than EDTA. To investigate the efficiency of chlorides versus EDTA in extracting heavy metals from contaminated soils, soil samples (pH 6.14±0.11) were collected from a local agriculture soil in Australia, artificially contaminated with either Pb, Cd or Cr at three different levels of 200, 400 and 600 mg kg -1 , and then packed in capped plastic flasks. Batch washing techniques were followed with either EDTA or FeCl 3 solutions (prepared at 4 different concentrations of 0.05, 0.1, 0.25 and 0.5 M), and soil suspensions were agitated for different time periods (from 5.0 min. to 60.0 min); afterward, the extraction efficiencies of the investigated metals were considered. The removal efficiency of Pb from the contaminated soil (200 mg Pb kg -1 ) after 5 minutes of EDTA application seemed to be relatively high (≈75%). Afterward this efficiency decreased gradually with time. The efficiencies of the extracted Cd and Cr by soil washing with EDTA increased significantly with increases in the agitating period. Generally, the extraction efficiencies by EDTA decreased noticeably with increasing levels of soil contamination. On the other hand, the efficiencies of Pb, Cd and Cr extractions were high -especially when increasing both the concentrations of applied FeCl 3 solution and the time of agitation. The results also highlighted that soil washing with FeCl 3 seemed to be more favourable over EDTA for rapid extraction of heavy metals from contaminated soils. The efficiencies of extracting heavy metals by soil washing with 0.5M FeCl 3 for only one hour were 93.79±2.35%, 97.4±2.45% and 81.75±7.86% for Pb, Cd and Cr, respectively.
