TL;DR: The Brazilian Soil Spectral Library (BSSL) as mentioned in this paper was developed in a joint partnership with the Brazilian pedometrics community to standardize and evaluate spectra within the 350-2500nm range of Brazilian soils.
Journal ArticleDOI
The role of Al-Goethites on arsenate mobility
Juscimar da Silva,Jaime Wilson Vargas de Mello,Massimo Gasparon,Walter Antônio Pereira Abrahão,Virginia S. T. Ciminelli,Tony Jong +5 more
TL;DR: Al-goethites showed good potential as adsorbents to remove As from water, and the presence of structural Al in the goethites enhanced considerably the As uptake capacity and stability under reducing conditions.
Journal ArticleDOI
Geochemistry and spatial variability of metal(loid) concentrations in soils of the state of Minas Gerais, Brazil
José João Lelis Leal de Souza,Walter Antônio Pereira Abrahão,Jaime Wilson Vargas de Mello,Juscimar da Silva,Liovando Marciano da Costa,Teógenes Senna de Oliveira +5 more
TL;DR: The objectives of this work are to evaluate the natural concentrations of metal(loid)s in pristine Minas Gerais soils and to interpret the spatial variability in concentration of these elements and to study the spatial geochemical diversity for the state.
