“…Five sets of experiments (Csupka et al, 1969;Øhlenschlaeger and Gissel-Nielsen, 1989;Øhlenschlaeger et al, 1993;Sarfraz et al, 2007) showed consistency in the lowest accumulating varieties between sites. Three other sets of experiments (Csupka et al, 1969;Gertsmann and Schimmack, 2006;Øhlenschlaeger and Gissel-Nielsen, 1991) showed little consistency in low accumulating varieties.…”

“…Heavy metals are extremely persistent in the environment; they are nonbiodegradable and nonthermodegradable and, at higher concentrations, accumulate and enhance the risk of metal contamination of the food chain (Sharma et al, 2007;Sarfaraz et al, 2007). Natural sources such as parental rocks and anthropogenic activities are releasing heavy metals in to soil environment.…”

This study was conducted to investigate the total concentration of cadmium and lead as well as their compartmentalisation by the modified BCR sequential extraction method. Also the mobility and contamination factor potential of cadmium and lead was evaluated in soils in Amol area, Iran. Total metals concentrations in Cd and Pb were 0.096±0.036 and 24.97±0.83 (µg g -1 ), respectively. The sum of the fractions was consistent with the total content of each metal. Cadmium was mainly associated with the reducible, exchangeable-acid soluble and oxidisable fractions. Lead was mainly associated with the residual, reducible and oxidisable fractions. Cadmium had a higher mobility potential in all soil samples than lead. Cadmium had a lower retention time than lead.

“…In fact, although many heavy metals are essential in small amounts for the optimal functioning of biological cycles, most of them exert toxic effects at the concentrations encountered in polluted environments (Sarfrazi et al 2007). Several studies have indicated a direct relationship between the concentrations of heavy metals in crops and the contamination levels found in soils (Nabulo et al 2008).…”

Increasing heavy metal applications to agricultural soils in the form of phosphatic fertilizers and/or atmospheric deposition have led to extensive research on the chemistry of Zn and Cu in soils. Cu(II) and Zn(II) sorption onto different soil fractions of three Mollisols and one Entisol from the southwest of Buenos Aires Province, Argentina, was studied. Different variables affecting the sorption capacity such as pH, cation exchange capacity, specific surface area (SSA), type and amount of clay minerals present, content of Fe-, Al-, and Mn-oxides and oxohydroxides, organic matter and electric charge parameters were investigated. To assess the monometal sorption, batch equilibrium experiments were performed using Cu(II) and Zn(II) metal solutions over a pH range from 4.0 to 7.0. The increase in metal sorption with increasing pH for both metal cations was attributed to an increase in the negative surface charges. At pH 5.0, Cu(II) showed more affinity than Zn(II) for reactive surface soil sites. Removal of organic matter via H 2 O 2 treatment (\2-mm OMR fraction) dramatically decreased the sorption of both cations; however, Cu(II) was sorbed more than Zn(II). The variation in SSA (obtained by water vapor adsorption) in \2-lm (clay fraction) and \2-mm (whole soil fraction) after Zn(II)/Cu(II) sorption at pH 4 and 6 reflected a different interaction between both cations and binding surface sites. Sorption isotherms correlated better with Langmuir than Freundlich equations. Sorption capacities (q max ) in \2-lm fraction, ranged from 166 to 111 mmol kg -1 for Cu(II), and from 62 to 31 mmol kg -1 for Zn(II). This study extends the understanding of the sorption mechanisms of Cu(II) and Zn(II) to agricultural soils from the semi-arid Pampean region of Argentina. An understanding of the local soil environment is important in order to reduce or prevent contamination of this valuable resource, especially from fertilizers and other such anthropogenic additions to the soil.
