“…Several studies have already shown that parent material has a strong influence on soil chemistry (e.g., Fuge et al, 1991;Palumbo et al, 2000;Salminen and Gregorauskiene, 2000;Acosta et al, 2011;Ramos-Miras et al, 2014). It is well-known also that regional geological setting is an influential determinant of soil geochemical baselines because their values depend not only on the bedrock lithology, but also on the occurrence of mineralised belts (Galán et al, 2008;Batista et al, 2013).…”

“…In area 2, there was more evidence of veins of Pb ores (Mello and Bettencourt, 1998). Several studies have already shown that parent material has a strong influence on soil chemistry (Acosta et al, 2011;Ramos-Miras et al, 2014;Rivera et al, 2015).…”

Studies of heavy metals are concentrate on clay fractions, but coarser fractions of the soil can constitute significant sources of structural forms of heavy metals. The aim of this study was to evaluate the occurrence of heavy metals in the structure of minerals of the sand and silt fractions of soils from three different parent materials (metamorphic rocks and granite) in southern Brazil using SEM/EDS -Scanning Electron Microscopy with Energy Dispersive Spectroscopy and with WD-EPMA -with Wavelength Dispersive-Electron Probe Microanalysis. We sampled soils from two areas naturally rich in heavy metals, with high mineral deposits (galena -PbS) hosted in carbonate rocks and phyllite/mica schist. The main form of Ba in the sand and silt fractions was as barite (BaSO 4 ). The precipitation of Ba and S from the soil solution occurred on the surface of silicate mineral particles. Due to the proximity of ionic radius of Ba-Pb, there was isomorphic substitution of Ba for Pb in the barite structure. The only primary mineral source of Pb in the coarse soil fractions was trioctahedral mica. Several secondary minerals in the silt and sand are sources of structural Pb: plumbogummite, plumboferrite, magnetoplumbite, and cerussite. There was a strong geochemical association of Pb-Fe-Mn. Zinc was also associated with Fe. The SEM/EDS/WD-EPMA techniques are important analyses to complement standard procedures, such as X-ray diffraction and total chemical digestion, in geochemical studies.

“…Background values are related to the source material and soil formation processes, which determine the amount and distribution of PTEs in the soil profile [17]. Several studies have shown relationships between background values of PTEs and soil properties, such as pH, clay content, iron, and aluminum oxides, organic matter [2,[20][21][22][23][24], mineralogy, and the elemental composition of the soil [12], indicating that these properties play important roles in the dynamics of PTEs.…”

The objectives of this study were to establish geochemical background values of aluminum (Al), iron (Fe), arsenic (As), barium (Ba), cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), vanadium (V), and zinc (Zn) for eastern Amazon soils and to assess the relationship between soil chemical and granulometric attributes using univariate and multivariate procedures. Samples from the topsoil (0–0.2 m) were collected in several areas with minimal or no human intervention. Pseudo total concentrations of potentially toxic elements were extracted via acid digestion and quantified via inductively coupled plasma optical emission spectrometry (ICP-OES). The results revealed that the soils present high acidity, low levels of cations and organic carbon, and highly heterogeneous geomorphological characteristics. The elements Fe (9300 mg kg−1) and Al (8200 mg kg−1) showed the highest mean concentrations in the study, while As (0.8 mg kg−1) and Cd (0.1 mg kg−1) presented the lowest levels. The results of this study indicate that the 90th percentile can be used to formalize quality reference values for the State of Pará and that the 98th percentile can be considered for areas rich in mineral deposits.
