“…Different methods are usually used to determine hazardous elements contamination in soil like contamination factor (C i f ), enrichment factor (EF), geoaccumulation index (I geo ), pollution load index (PLI) etc. [9]. The EF of an area indicates the relative enrichment in any contaminant when compared to pre-industrial soils from the same environment [10,11].…”

“…When China is shown to be a net embodied cultivated land exporter throughout the concerned years, the variation of embodied cultivated land balance is closely related to the country's international trade pattern. To assess the ecological risk and to understand the transport processes of heavy metals in an agricultural ecosystem, Liu et al (2014) investigate the concentrations of heavy metals in agricultural soils (As, Cd, Cr, Cu, Mn, Ni, Pb, Zn) and in wheat plants at different stages of growth (Cd, Pb, Zn) near the Fengfan leadacid battery factory in Baoding city of China, showing that the potential health risks due to the cumulative risk of all heavy metals through the consumption of wheat berries exceed unity for rural inhabitants but not notable for urban inhabitants. evaluate global scientific research on hydropower sustainable development with a long time span ranging from 1991 to 2012.…”

“…In the past few decades, soil pollution by heavy metals has become one of the major concerns as heavy metals are of bioaccumulation, high toxicity, and non-degradation [1][2][3]. Human activities such as transport, fertilization, mining activities and other industrial production often result in a large accumulation of heavy metals in soils [4].…”

Abstract:The effect of enhancement agents on the efficiency of electrokinetic (EK) remediation of contaminated soils has been extensively studied in the past few years. However, the larger scale ex suit EK remediation with enhancement agents has been rarely reported. In this study, medium-scale EK remediation tests (20 kg dry soil at a single test) enhanced by EDTA, tartaric acid, citric acid and acetic acid were carried out to remove Cd and Zn from the contaminated soil. The removal efficiencies of Cd and Zn were enhanced by EDTA, tartaric acid and citric acid, and the enhanced effect of acetic acid on removal efficiencies of Cd and Zn was less. The highest removal efficiencies of Cd and Zn were 22.2% (citric acid) and 23.3% (tartaric acid), respectively. Low removal efficiencies were ascribed to the accumulations of Cd and Zn in F1 (exchangeable) and F2 (carbonate-associated) fractions in the middle section soils after EK remediation for all tests. After EK remediation, the F3 (reducible) concentrations of Cd and Zn, lower than initial concentrations, increased with the distance from the anode for all tests. The results suggested that F3 fraction can be transformed into F1 and F2 fractions, and F1, F2 and F3 fractions were removable during the EK remediation. Comparing with the control test (CT), more variations of total concentration and speciation of Cd and Zn were found, indicating apparent effects of enhancement agents on heavy metal removal during EK remediation. The results are significant for the enlargement of ex suit EK remediation.
