“…In southern Brazil, with subtropical climate and annual average rainfall of 2000 mm, it was found values of up to 3200 mg kg −1 Cu (Mirlean et al, 2007). In addition to Cu, other metals may be present in fungicide mixtures, other pesticides, or fertilizers, which can increase their contents in the soil (Mirlean et al, 2007;Jiao et al, 2012;Santos et al, 2013;Silva et al, 2014).…”

Contamination of vineyard soils by the continuous use of cupric fungicides and fertilizers has been a worldwide concern. The objective of this study was to determine the total concentration of Cu, Zn, Fe, Mn, Ni and Pb from vineyard soils of a semiarid region in Brazil. Soil samples at 0-20 and 20-40 cm depth were collected in areas under 5, 6, 8, 10, 12, 15, 16 and 30 years of cultivation, and compared with native vegetation areas. Samples were digested and total metal concentrations were determined by atomic absorption spectrophotometer. In general, concentrations of Mn, Ni, Fe and Pb were similar to those values found in the reference area, being regarded as background concentrations. On the other hand, Zn and Cu were mainly derived from the widespread use of fertilizers (e.g., phosphate application) and cupric fungicides, respectively. Discriminant analysis clearly demonstrated higher metal accumulation in surface soil samples, chiefly Zn and Cu owing to Zn and Cu-containing chemicals and accumulation of organic matter. This tool was also useful to differentiate between natural and anthropogenic inputs of metals into soils. The high enrichment factor values for Cu and Zn showed that both were mainly derived from anthropogenic sources.

“…The involvement of acid solutions and/or chelating agents allows for the removal of both the most and the least mobile fractions of metals in cationic form, potentially achieving very high removal efficiency if the operative conditions of the process are correctly chosen and optimized [4]. The choice of an appropriate washing solution is a critical point, not only to guarantee the required performances, but also to avoid any problems related to its final disposal [5][6][7]. The management of spent washing solutions (SWSs), in fact, makes up a significant cost of the whole remediation process.…”

Soil Washing Optimization, Recycling of the Solution, and Ecotoxicity Assessment for the Remediation of Pb-Contaminated Sites Using EDDS

This paper presents the results of an experimental study aimed at investigating the applicability of ethylenediamine-N,N -disuccinic acid (EDDS) as a washing solution for the remediation of Pb-contaminated soil. All aspects of the treatment are analyzed and optimized, including the reuse and the final disposal of the EDDS spent solution. Different molar concentrations of the washing solutions and the efficiencies of varying solid/liquid ratio are tested at different pH values. More than 90% of the mobile Pb fraction is removed in about 24 h at pH 6. Accordingly, soil toxicity strongly decreases as a consequence of the treatment. The regenerated solution exhibits a reduced, but not negligible, extractive capacity. The total extraction of Pb is approximately 50% of the initial value after one regeneration cycle, and almost 20% after a second regeneration cycle. Respirometric tests, conducted using an activated sludge sampled in a municipal wastewater treatment plant, indicate that the spent solutions are not biodegradable, but they do not exert any toxic effect on the biomass. On the contrary, tests on regenerated solutions displayed the same biodegradability as the fresh ones.

“…Considering the fragile vineyard soils in the São Francisco Valley and the intensive agricultural system, multi-temporal studies to assess soil fertility changes are essential for soil sustainability. Most of the studies on vineyard soils were carried out in temperate and subtropical settlements and focused mainly on carbon balance, biomass production, and contamination of vineyard soils (Santos et al, 2013;Schmitt et al, 2013;Brunori et al, 2016). Additionally, data are very scarce for vineyard soil changes under cultivation in arid and semiarid regions.…”

Cultivation can substantially change soil quality through improvement or degradation of the physical and chemical characteristics. Vineyard soils are sensitive to soil changes due to the intensive chemical input. This study assesses the soil fertility changes in vineyard soils of the São Francisco valley in Northeastern Brazil during different cultivation time spans (5, 6, 8, 10, 12, 15, and 16 years). An area with natural vegetation (Caatinga) was used as a reference area. We analyzed pH, exchangeable contents of Ca, Mg, Na, K, and Al, potential acidity (H+Al), available P, total organic matter, sum of bases, CEC, Al saturation, and base saturation at depths of 0-20 and 20-40 cm. Univariate and multivariate analyses were used for data evaluation. The results showed that soil fertility changes were closely related to cultivation time spans. Contents of organic matter, Ca, Mg, and K were increased in most of the vineyard soils. The management of P fertilization deserves attention as the very high concentrations in soil are prone to leach and can contribute to triggering eutrophication. Discriminant and factor analyses proved to be useful tools for distinguishing the effects of management in the cultivated areas and helping to achieve sustainable land use in such fragile agro-ecosystems.
