“…In contrast, they found that Ni was present in greatest amounts in olivine, which weathers rapidly, with some Ni leaching down through the soil horizons and remaining Ni being taken up by smectite and Fe oxyhydroxide. Quantin et al (2008) and Kierczak et al (2007) also found that Cr was less mobile than Ni in soils overlying ultramafic rocks, when studying the PTEs' bioavailability for plant uptake. Both authors concluded that Cr was tightly bound to recalcitrant primary Fe oxides and Quantin et al (2008) concluded that Ni was transferred more readily to secondary minerals during weathering.…”

“…These elevated PTE levels have been found to be due to geogenic (Wragg 2005) and anthropogenic (Dao et al 2012) sources of contamination or a combination of both (Facchinelli et al 2001;Zhang et al 2008;Rodrigues et al 2006;Mostert et al 2012). Elevated nickel (Ni) and chromium (Cr) from geogenic sources have been identified worldwide (Quantin et al 2008;Megremi 2010;Kierczak et al 2007;Johnson et al 2012;Barsby et al 2012).…”

Potentially toxic elements (PTEs) including nickel and chromium are often present in soils overlying basalt at concentrations above regulatory guidance values due to the presence of these elements in underlying geology. Oral bioaccessibility testing allows the risk posed by PTEs to human health to be assessed, however bioaccessibility is controlled by factors including mineralogy, particle size, solid phase speciation and encapsulation. X-ray diffraction (XRD) was used to characterise the mineralogy of 12 soil samples overlying Palaeogene basalt lavas in Northern Ireland and non specific sequential extraction coupled with chemometric analysis was used to determine the distribution of elements amongst soil components in 3 of these samples. The data obtained were related to total concentration and oral bioaccessible concentration to determine whether a relationship exists between the overall concentrations of PTEs, their bioaccessibility and the soils mineralogy and geochemistry.Gastric phase bioaccessible fraction (BAF%) ranged from 0.4% to 5.4% for chromium in soils overlying basalt and bioaccessible and total chromium concentrations are positively correlated. In contrast the range of gastric phase BAF for nickel was greater (1.4 to 43.8%), while no significant correlation was observed between bioaccessible and total nickel concentrations. However nickel BAF was inversely correlated with total concentration. Solid phase fractionation information showed that bioaccessible nickel was associated with calcium carbonate, aluminum oxide, iron oxide and clay related components, while bioaccessible chromium was associated with clay related components. This suggests that weathering significantly affects nickel bioaccessibility, but does not have the same effect on the bioaccessibility of chromium.

“…The distinct differences in Cr and Ni concentrations between soils can be taken as an indication of differences in degree of weathering and/or mineralogical compositions of the parent rocks [83,86]. Cr most commonly occurs as an accessory mineral (e.g., chromite) in serpentinites, whereas Ni primarily exists as impurity on the crystal structure of mineral phases in serpentine [87,88]. On the other hand, S8 sample, determined by XRD to contain dolomite, calcite, and quartz (Table 1), shows high concentrations of CaO, MgO, and SiO 2 (Table 2), confirming the presence of these mineral Table 2: Chemical composition of the selected rock (R1-R10) and soil (S1-S8) samples from the Kızılgedik area as determined by wavelength dispersive X-ray fluorescence (WDXRF) analysis.…”

The aim of this study was to investigate natural and anthropogenic processes governing the chemical composition of alkaline groundwater within a fractured rock (ophiolitic mélange) aquifer underlying a seasonally inhabited headwater area in the Aladaglar Range (Adana, Turkey). In this aquifer, spatiotemporal patterns of groundwater flow and chemistry were investigated during dry (October 2011) and wet (May 2012) seasons utilizing 25 shallow hand-dug wells. In addition, representative samples of snow, rock, and soil were collected and analyzed to constrain the PHREEQC inverse geochemical models used for simulating waterrock interaction (WRI) processes. Hydrochemistry of the aquifer shows a strong interseasonal variability where Mg-HCO 3 and Mg-Ca-HCO 3 water types are prevalent, reflecting the influence of ophiolitic and carbonate rocks on local groundwater chemistry. R-mode factor analysis of hydrochemical data hints at geochemical processes taking place in the groundwater system, that is, WRI involving Ca-and Si-bearing phases; WRI involving amorphous oxyhydroxides and clay minerals; WRI involving Mg-bearing phases; and atmospheric/anthropogenic inputs. Results from the PHREEQC modeling suggested that hydrogeochemical evolution is governed by weathering of primary minerals (calcite, chrysotile, forsterite, and chromite), precipitation of secondary minerals (dolomite, quartz, clinochlore, and Fe/Cr oxides), atmospheric/anthropogenic inputs (halite), and seasonal dilution from recharge.

“…Under tropical climate, serpentine derived soils undergo an elevated degree of weathering, which influences the soil particle size. In the recent decades great attention has been paid to serpentine soils as major sources of heavy metal pollution (Kierczak et al, 2007;Lee et al, 2004;Lottermoser, 1997;Tashakor et al, 2013). While, decomposition of serpentine rocks occurs a mixture of variable proportions of minerals form which according to weathering intensity range from primary minerals to secondary phyllosilicates and lastly to Mn and Fe oxides.…”

The proportion of various grain size particles in soils is controlled largely by climate condition and moisture regimes. In general, tropical regions produce thick layers of fine grain soils due to high degree of weathering. Depends on the texture of soils, the capacity for storage of heavy metals changes. Serpentinized-ultramafic soils of Malaysia are of concern in this study containing high natural content of chromium, nickel and cobalt. These soils are comprised of a mixture of variable minerals ranging from inherited serpentines to magnetite, chlorite, ilmenite and minor to trace amounts of allochthonous quartz, clay minerals and phyllosilicates, such as kaolinite oxides and hydrous oxides of iron and manganese. The particle size distribution of serpentinite soils in Malaysia has received very limited study previously. This study attempts to find a relationship between the partitioning of Cr, Ni and Co among different soil size fractions with the mineralogical composition of serpentinite soils.
