A Potential Method of Chemical Remediation of Arable Lands Polluted with Heavy Metals

Abstract

Abstract Soils from agricultural areas are under anthropic pressures, one of the causes being atmospheric deposition of heavy metals. In order to prevent that diffuse pollution affects the soil for long term it is important to reduce the releases of pollutant from air and water. In this paper it was analysed a potential method of chemical remediation applied to the case of an accidental situation of arable soil pollution with heavy metals. The technology of remediation proposed is based on a chemical fixation by adding a reagent into the contaminated soil where it reacts with heavy metals and form insoluble complexes. The organic reagent is one of the best-known and most frequently used in extraction and trace analysis. So, the chemical remediation proposed could decrease the migration of heavy metals in soil and subsequently, in water, plant and other environmental media.
