“…The chemical reactivity of zinc in soils is mainly governed by retention and release reactions taking place within the complex matrix of the system (Shi et al, 2005;Singh et al, 2006;Zhang et al, 2006;Lombnaes et al, 2008;Shi et al, 2008;Šváb et al, 2008). The experimental design of this study mainly depends on the release of zinc with humic substances i.e.…”

“…Amongst several solutions used to date, EDTA has been the most relevant and successful for heavy metals extraction compared to the other organic and inorganic solvents [58]. The literature available shows the technological utility in flushing out heavy metals, such as Cd, Cr, Cu and Zn [59,60]. Soil flushing becomes successful and cost-effective if the soil to be treated is permeable in nature to let the solution pass readily through the layers of soil [42].…”

This paper revises the fundamental facts about potentially toxic elements belonging to the group of heavy metals. The study highlights the ongoing soil pollution status affected by these non-biodegradable elements, the basic characteristics of these metals that make them toxic, their mode of accumulation in different trophic levels, their toxic effect on human beings and the probable remediation technologies being used to remediate soils contaminated with heavy metal when the pollution problem has evolved. The technologies focused on solidification, soil washing, soil flushing, electro-kinetic remediation and phytoremediation are presented. The choice of the technology to be used for remediation depends on the condition of the soil and the extent of contamination. Conventional electro-kinetics is the most effective and rapid technology, but on the scale of ecosystem restoration, phytoremediation is an eco-friendly, green and cost-effective solution.

“…When infiltration is similar to rainwater, it is possible to study the mobility of pollutants under controlled laboratory conditions (Navarro and Martí-nez, 2008). Analytical and numerical methods applied to the results of leaching tests may also be useful for evaluating the efficiency of different remediation measures (Brusseau, 1994;Shackelford and Glade, 1997;Sváb et al, 2008).…”

Mercury mine waste contains other toxic metals in addition to Hg, such as Ag, Cd, Cu, Ni, Pb, Fe, Mn, As, and Sb, which may contribute to environmental pollution. Leaching characteristics of mine waste treated by solar thermal desorption were studied, and removal and mobilization processes were evaluated. Concentrations of Cd, Ni, and Pb in mine waste leachates before thermal treatment do not exceed the limits in European standards, and after the treatment, their concentration decreased significantly in some samples. Hg is the only metal with concentrations above the European leaching limits, although, in the treated samples, the concentrations of dissolved Hg decreased significantly, showing the effectiveness of the thermal treatment. Thus, in the mining wastes sample AS, Hg concentrations decreased from 1100 lg/L in the original sample to 73 lg/L in the treated sample, although this concentration is above the European leachate concentration levels (30 lg/L). In the calcine sample M03, Hg leached only decreased from 13 to 9 lg/L in the treated sample, although when characterized by percolation experiments, these levels were below the European leachate limits for nonhazardous solid-waste landfills. In the soil samples M02 and BS, the Hg leaching showed an opposite behavior, indicating in the Azogue soil sample M02 that the Hg concentration decreased from 66 to 6 lg/L in the treated sample, while in the Bayarque soil sample BS, the concentration of leached Hg increased from 9 to 51 lg/L in the treated sample. Results of geochemical modeling showed that the dominant species in the leachates of the untreated samples were HgClOH, Hg(OH) 2 , HgCl 2 , HgCl 3 -, and Hg 0 , which was in agreement with the high Hg and chloride concentrations in some leachates. In the leachates of the treated samples, the dominant species were Hg 0 , Hg(OH) 2 , HgClOH, and HgCl 2 .
