The increased exploitation of rare-earth elements (REEs) over the past few decades and the disposal of various products containing these elements have prompted numerous environmental studies and the need to establish regulatory guidelines. We determined the concentration of REEs in topsoil samples of 33 soil profiles collected from areas of different geological settings in Cuba. The average REE concentrations...
The Borborema Province in northeast Brazil represents the western portion of the extensive geological Brasiliano-Pan African orogenic system. It is characterized by voluminous granites, which originate from the melting of igneous rocks. We investigated the influence of metaluminous granite mineralogy on the geochemistry of rare earth elements (REEs) in rocks and soils across a climosequence. Mineralogical,...
Heavy metal contamination has long been a water quality concern worldwide. Most studies have focused on heavy metal concentration in water through suspended sediment and bottom sediment; however, the concentration transported by river-bottom sediment, known as bedload, has not been taken into account. In order to fill this gap, this study aimed to determine the concentration of Hg, Pb, Cd, Ni, Cu,...
This study provides new insights into the effects of a parent material on inherent soil fertility. We describe the mineralogy and geochemistry of I- and S-type granites and their effect on soil fertility under similar environmental conditions in Borborema Province, NE Brazil, using standard mineralogical, geochemical and soil analyses as well as multivariate analysis and geographic information system...
Studies regarding the influence of emergent vegetation on sediment transport are scarce and have mainly focused on flume conditions. To fill this gap and also meet the international need, we aimed to evaluate the influence of emergent vegetation (Echinodorus macrophyllus) on sediment transport of Capibaribe River, Brazil. Bedload and suspended sediment measurements were carried out using the US BLH...
