“…Heavy metals have low mobility in relation of Ca 2+ and Mg 2+ and high persistence in the environment, and they accumulate in the soil profile (Rivera et al, 2015). In geochemical processes, Ba is associated with K because of the similarity of their ionic radius (Ba -0.135 nm; K -0.133 nm) (Klein and Hurlbut, 1993).…”

“…This result shows the importance of the metamorphism process in enhancing heavy metals in the soil fractions of areas 1 and 2 in relation to area 3. The metamorphism in the area studied generated hydrothermal fluids rich in Pb, Zn, and Cu (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.

“…Specifically, Ghaleno et al (2015) reported anthropogenic and agricultural source of cadmium could lead to relative enrichment in the receiving environment. According to Mazurek et al (2017), Rivera et al (2015), the distribution of the heavy metals in the soil depends on their geoavailability and pedochemical enrichment. This could also account for variation in the EF among the various locations and seasons.…”

-accumulation index, enrichment factor and quantification of contamination of heavy metals in soil receiving cassava mill effluents in a rural community in the Niger Delta region of Nigeria, Molecular Soil Biology, 8(2): 7-20 (doi: 10.5376/msb.2017.08.0002) Abstract This study investigated enrichment factor, geo-accumulation index and quantification of contamination of heavy metals in cassava mill effluents contaminated soil by smallholder cassava processors in a rural community in the Niger Delta region of Nigeria. Data used for the environmental risk assessment is from secondary sources. The assessment was carried out under two background scenarios viz: geometric (BGM) and median mean (BMM). 50% of mean detected individual metals was used as mean data for location that the metal was not detected. Assessment was carried out following well established protocol. Results showed that enrichment factor (EF), geo-accumulation index (Igeo), improved Nemerow Index (INI), Metal enrichment index (MEI) and quantification of contamination (QoC) in soil heavy metals (viz: Fe, Cr, Zn, Cu, Co, Ni, Mn, Pb and Cd) receiving cassava mill effluents in a rural community of the Niger Delta region of Nigeria revealed un-contamination to moderately contamination for Igeo, NMI, background rank to significant enrichment for EF, no enrichment to moderate enrichment for MEI, and positive values of quantification of contamination is an indication of pollution/contamination due to anthropogenic sources. The study further showed that cassava mill effluents are contributing to soil heavy metal contamination in study area.
