“…The correlation coefficient of the present study ( Table 3) corroborate those that were obtained by Arias et al (2005), who observed a positive correlation between the pH and the maximum adsorption and affinity coefficients of Cu 2+ in 27 acid soils from Spain. According to Bradl (2004), the pH is the most important soil attribute that influences metal adsorption.…”

“…In addition to these attributes is MnO, which even at low concentrations in the soil has high reactivity for adsorbing many heavy metals (KÄMPF et al, 2009;BRAZ et al, 2013aBRAZ et al, , 2013b. Although, several studies converge on the soil chemical properties as the most influential in the adsorption of metals in different regions around the world (ARIAS et al, 2005;CERQUEIRA et al, 2011b), there are few publications with Amazonian soils (BRAZ et al, 2013a).…”

Studies of heavy metals adsorption in soil play a key role in predicting environmental susceptibility to contamination by toxic elements. The objective of this study was to evaluate cadmium (Cd) and copper (Cu) adsorption in surface and subsurface soil. Samples of six soils: Xanthic Hapludox (XH1 and XH2), Typic Hapludox (TH), Typic Rhodudalf (TR), Typic Fluvaquent (TF), and Amazonian dark earths (ADE) from Eastern Amazonian, Brazil. The soils were selected for chemical, physical and mineralogical characterization and to determine the adsorption by Langmuir and Freundlich isotherms. All soils characterized as kaolinitic, and among them, XH1 and XH2 showed the lowest fertility. The Langmuir and Freundlich isotherms revealed a higher Cu (H curve) than Cd (L curve) adsorption. Parameters of Langmuir and Freundlich isotherms indicate that soils TR, TF and ADE has the greatest capacity and affinity for metal adsorption. Correlation between the curve adsorption parameters and the soil attributes indicates that the pH, CEC, OM and MnO variables had the best influence on metal retention. The Langmuir and Freundlich isotherms satisfactorily described Cu and Cd soil adsorption, where TR, TF and ADE has a lower vulnerability to metal input to the environment. Besides the pH, CEC and OM the MnO had a significant effect on Cu and Cd adsorption in Amazon soils. Key words: Amazonian dark earths. Environmental management. Heavy metals. Isotherm.

“…They occur mainly through the adsorption and formation of salts, and through the creation of chelated and complex connections. The amount of zinc and copper adsorbed by soil and rock components under equilibrium conditions depends basically on the content of organic matter, clay minerals and metal oxides and hydroxides (Stumm and Morgan 1981;Ross 1994;Arias et al 2005).…”

Common occurrence of copper and zinc in groundwater and their diverse mobility in the environment make these metals sensitive indicators of industrial and municipal pollution of freshwaters. An analysis of the collected data allowed for a description of the factors and processes that induce changes in the concentration of these metals in the soil, rock and groundwater. Sorption, ion exchange and oxidation-reduction processes, dissolution and precipitation of minerals, and reactions involving organic matter significantly affected the mobility of copper and zinc. The study employed hydrogeochemical methods to obtain comprehensive interpretative data. Its results showed that the variability of the composition of exchangeable cations was due to instability of chemical composition of precipitation. Different activities of Cu and Zn in the solution introduced into the rocks led to the establishment of new quasi-equilibrium states between the adsorbent and the adsorbate. At very low copper and zinc concentrations in groundwater, zinc was more easily retained in the solid phase, and it was more difficult to extract. In contrast, a laboratory static batch experiment utilizing high concentrations of the elements in the solutions showed their different behavior. The sorption of copper occurred more easily than the sorption of zinc, as evidenced by the study results and the calculated parameters of sorption maximum, binding constant, and degree of surface coverage of the solid phase by adsorbed copper and zinc according to a single Langmuir equation.

“…Studies using chemical extractors demonstrated that Cu availability is higher in acid and sandy soils containing low concentrations of organic matter (Brun et al 2001;Chaignon and Hinsinger 2003;Pietrzak and McPhail 2004;Arias et al 2005). However, estimations of the total concentration of Cu in the soil (or the amount of Cu extractable using various methods) are ineffective for predicting the Cu absorption and its toxicity to plants (Brun et al 1998).…”

Copper uptake, accumulation and physiological changes in adult grapevines in response to excess copper in soil

Aims This study investigated Cu uptake and accumulation as well as physiological and biochemical changes in grapevines grown in soils containing excess Cu. Methods The grapevines were collected during two productive cycles from three vineyards with increasing concentrations of Cu in the soil and at various growth stages, before and after the application of Cu-based fungicides. The Cu concentrations in the grapevine organs and the macronutrients and biochemical parameters in the leaf blades were analyzed.Results At close to the flowering stage of the grapevines, the concentration and content of Cu in the leaves were increased. However, the Cu concentrations in the roots, stem, shoots and bunches did not correlate with the metal concentrations in the soil. The application of Cu-based fungicides to the leaves increased the Cu concentrations in the shoots, leaves and rachis; however, the effect of the fungicides on the Cu concentration in the berries was not significant. The biochemical analyses of the leaf blades demonstrated symptoms of oxidative stress that correlated with the Cu concentrations in soil. Conclusions The increased availability of Cu in soil had a slight effect on the levels and accumulation of Cu in mature grapevines during the productive season and did not alter the nutritional status of the plant. However, increased Cu concentrations were observed in the leaves. The evidence of oxidative stress in the leaves correlated with the increased levels of Cu in soil.
