“…Initially, soil pH increased with the addition of both amendments, compared to untreated soil. Since these results were in agreement with those found in a previous study [47], this soil pH modification was slight (2.87% = BC and 2.87% = PF), and there was no correlation with HM bioavailability [48]. Soil acidification observed upon increasing of the experiment time for all treatments was possibly due to soil organic matter mineralization [49] and/or to H+ formation by the fertilizer solubilization [50].…”

Remediation strategies are capable to mitigate negative effects of heavy metals (HMs) on soils. The distribution of cooper (Cu), zinc (Zn), and chromium (Cr) was evaluated in a contaminated soil after adding biosolid compost (BC) and phosphate fertilizer (PF). A greenhouse assay and sequential extraction procedure were performed to determine the fractionation of HM in contaminated and remediated soil. In BC treatment, among 4 to 6% of Cu was associated with soil humic substances. Without amendments and with fertilizer application, Zn solubility increased by 15.4 and 8.4%, respectively, with experiment time. Although Cr was significantly adsorbed to the inorganic fraction, with compost application there was a transfer to organic fraction. A single amendment application is not suitable for immobilizing all metals of concern, because there are diverse union's behaviors between HM and soil matrix. As the organic matter and phosphate fertilizer were effective in reducing mobility of Cu, the organic matter was more effective in the immobilization of Cr, and inorganic amendment induced the Zn precipitation, results from this pilot study suggest a combined use of these two amendments for soil remediation strategies. However, liming may be further needed to prevent soil acidification on longer time scales. Also, we propose the use of chemical and biological remediation strategies for potential improvement of effectiveness.

“…For comparisons between the findings of other studies in the neighbouring area (Bech et al 2005;Tume et al 2006a, b) and reports of trace elements in (Boluda et al 1993;Micó et al 2006;Rodríguez-Martín et al 2006), the median is preferred over the mean for statistical analyses, as the latter is strongly affected by outliers in the data set. In a study of surface soils (0-20 cm), trace element concentrations of Ba, Cu, Cr, Ni, Pb, Sr, V, and Zn (aqua regia-extractable; 2 mm fraction) at different points in Torrelles and Sant Climent (35 km S of the study area), Bech et al (2005) found median concentrations of Cu (22.4 mg kg −1 ), Pb (34.2 mg kg −1 ), and Zn (78.1 mg kg −1 ).…”

“…In Catalonia, Spain, Bech et al (1993), Tobias (1995), andTobias et al (1997a, b) carried out preliminary studies in the municipal districts of Gava, Castelldefels, and Viladecans. Heavy metal concentrations have also been studied in the soils of the Torrelles and Sant Climent municipal districts (Bech et al 2005;Tume et al 2006aTume et al , b, 2008. However, attempts to study soils in Manresa have been very limited and remain largely unpublished (Bech et al 1992).…”

The aims of this study were to determine the contents of cadmium (Cd), copper (Cu), lead (Pb), zinc (Zn), aluminium (Al), and iron (Fe) (aqua regia-extractable) in 27 soil plots (54 samples) from Manresa, NE Spain, and to establish relationships between heavy metals and some soil properties. The main soil types were surveyed and the median concentrations (mg kg(-1)) obtained were Cd 0.28, Cu 20.3, Pb 18.6, Zn 67.4, Al 22,572, and Fe 21,551. Element concentrations for these soils were lower than the published values for the Valencia region (Spain) and Torrelles and Sant Climent municipal districts (Catalonia, Spain). In terms of soil properties, the results of this study suggest that, in Manresa soils, both trace element adsorption and retention are influenced by several properties such as clay minerals, carbonates, organic matter, and pH. All element contents were positively correlated with clay content. Pb and Zn were negatively correlated with pH and CaCO(3).

“…The concentrations of trace metals (Cr, Cu, Ni, Pb, Zn, Fe and Cd) were measured using an Inductively Coupled Optical Emission Spectrometer (Perkin Elmer Optima 5300 DV). Reagent blanks, standard reference soil samples, and internal control samples were also analysed in order to monitor analytical accuracy and precision (Tume et al, 2006).…”
