Heavy metal pollution in soil and water is a global environmental concern. Tiller. Heavy metal pollution problem arise when the heavy metals are mobilized into the soil and absorb by the plants or transported to the ground water. Further, the remediation technologies can be divided as physical remediation, chemical remediation and biological remediation. Swaine, D.L. Due to the increasing awareness among the public and the detrimental effects of these contaminants on human health, scientific communities are focusing on development of some new technologies for removal of these metals from contaminated soils.

The remediation technologies described above are costly, time-consuming and laborious, so efforts are made to increase the solubility of these metals in the soil so that they can be freely available for the removal. 1976. Soil pollution with heavy metals draws a serious concern because of their detrimental effects on the living biota. The persistent and non-biodegradable nature of heavy metals eases their accumulation in the environment. During the last few decades, rapid urbanization, industrialization, injudicious and faulty agricultural practices influence the release of metal contaminants in the agricultural fields. Tiller and L.R. de Vries, M.P.C. The effects of heavy metal contamination on soil are quite alarming earth. The influence of these heavy metals on plants and their metabolic activities caused by the geological and biological redistribution of heavy metals through pollution of the air, water and soil were briefly discussed in this article. 1986. by MedCrave Group is licensed under a Creative Commons Attribution 4.0 International License.

Griffis. In soil replacement method, the contaminated soil is partly replaced by clean soil so as to minimize the concentration of contaminant in the soil.5 However, this method is costly and is feasible only in a small area. A peak in lead usage was noted at the time of the Roman Empire; metal use accelerated during the Industrial Revolution of the nineteenth century, and since then heavy metals have become ‘essential’ to modern society because of the range of metal products used. Page, A.L. Carlton-Smith. On the other hand, phytostabilization refers to the use of plants to reduce mobility and bioavailability of the metals in the soil. 1982. The presence of large amounts of heavy metals in a soil could also lead. Use and disposal of contaminated dredged material. C.H., and D.J. Cultivation of crops on contaminated sites may result in both growth inhibition and tissue accumulation of heavy metals with resulting possible risks to humans health. Effects of annual and accumulative applications of sewage sludge on assimilation of zinc and cadmium by corn (. Therefore, a 1-year incubation experiment was carried out to investigate the effect of biochar produced from bamboo and rice straw (at temperatures ≥500 °C) on the heavy metal (cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn)) extractability and enzyme activity (urease, catalase, and acid phosphatase) in a contaminated sandy loam paddy soil.

Group, All rights reserved. Moreover, heavy metals can significantly affect the soil ecosystems and biological activity in the soil. In: van Driel, W, H.N. Moreover, the amendments used for immobilizing the contaminants may not be specific for a particular metal and thus can lead to release of a toxic metal into the soil. The samples were taken to the laboratory to measure their heavy metal concentration, soil texture, pH, electrical conductivity, cationic exchange capacity, organic matter, and carbonate contents. 1979. 1983.

The estimated total (all-time) and annual amounts of these metals dispersed through the atmosphere are presented in Table 1.

The various in-situ and ex-situ technologies available for contaminated soils are employed to reduce, remove and degrade the heavy metals from the soil. Bingham. Smilde, K.W., and B. van Luit. Related Papers. and Z. Liu. However, being costly, laborious and complicated process, its application in removal of contaminants from soil is limited. de Vries, L.H. Williams. 1973. Hughes, M.K., N.W. Cary, and R.M. The metals extracted by this method are recovered from the leachate by using chelating agents, surfactant etc.6 In chemical fixation, some reagents are added to the contaminated soils that form insoluble bond with the heavy metals and decrease their mobility in the soils.7 The soil contaminated by heavy metals can be remediated by the process of electrokinetic remediation, which involves the application of high voltage to the soil for the removal of metal.8 Lastly, the process of vitrification involves heating of the soil at very high temperature (1400-2000°C) so that the pollutant gets volatilize or decompose. Hall, and C.N. Salt DE, Blaylock M, Kumar NPBA, et al. • Higher clay content and soil depth decreased the effect of HM contamination on EAs. Tiller, M.P.C.
