Nanoparticles and interfaces with toxic elements in fluvial suspended sediment
(Universidad de la Costa, 2021)
Studies examining nanoparticles (NPs) and hazardous elements (HEs) contained in suspended sediments (SSs) are vital for watershed administration and ecological impact evaluation. The biochemical consequence of titanium-n ...
Titanium nanoparticles in sedimented dust aggregates from urban children’s parks around coal ashes wastes
(Corporación Universidad de la Costa, 2021)
Recently, an increased interest in nanoscience applications can be observed in various fields. Soils around coal power plants may contain potentially hazardous elements (PHEs) and nanoparticles (NPs), which can be neo-produced ...
Application of Andesite Rock as a Clean Source of Fertilizer for Eucalyptus Crop: Evidence of Sustainability
(Universidad de la Costa, 2020-02-05)
Global demineralization of agricultural soils due to unsustainable use of highly soluble fertilizers and intensive exploitation is an issue of increasing concern. Methods of remineralization include the application of ...
Nanominerals assemblages and hazardous elements assessment in phosphogypsum from an abandoned phosphate fertilizer industry
(Universidad de la Costa, 2020)
The present work investigates hazardous elements and nanomineralogical assemblages of phosphogypsum waste from an abandoned phosphate fertilizer industry located in Santa Catarina state (Brazil). Correlations between the ...
Biophysical matter in a marine estuary identified by the Sentinel-3B OLCI satellite and the presence of terrestrial iron (Fe) nanoparticles
(Corporación Universidad de la Costa, 2021)
The analysis of marine matter using the Sentinel-3B OLCI (Ocean Land Color Instrument) satellite is the most advanced technique for evaluating: the absorption of colored detrital and dissolved material (ADG_443_NN), total ...
Nanoparticles as vectors of other contaminants in estuarine suspended sediments: natural and real conditions
(Corporación Universidad de la Costa, 2021)
Studding the behaviour and danger of nanoparticles (NPs, minerals and amorphous phases) in the estuarine ecosystem is presently incomplete by the lack of measureable description of NPs in the ecological conditions, such ...
The role of roots plants and soil characteristics in coal mining areas: geochemical and nanomineralogy information still without details
(Corporación Universidad de la Costa, 2021)
In worldwide coal mining, the rejects have a smaller particle size, which ends up favoring the concentration of toxic elements and oxidative potential of the respirable fraction of powdered mined coals. Evidence of the ...
The role of airborne particles and environmental considerations in the transmission of SARS-CoV-2
(Geoscience Frontiers, 2021-04-05)
Corona Virus Disease 2019 (COVID-19) caused by the novel coronavirus, results in an acute respiratory
condition coronavirus 2 (SARS-CoV-2) and is highly infectious. The recent spread of this virus has caused
a global ...
Metal-enriched nanoparticles and black carbon: A perspective from the Brazil railway system air pollution
(Corporación Universidad de la Costa, 2021)
Having a better understanding of air pollutants in railway systems is crucial to ensure a clean public transport. This study measured, for the first time in Brazil, nanoparticles (NPs) and black carbon (BC) on two ground-level ...
Multianalytical approach of stay-in-place polyvinyl chloride formwork concrete exposed to high temperatures
(Universidad de la Costa, 2020-03-31)
This work presents results of the first study of the variation by exposure to high temperatures from two stay-in-place polyvinyl chloride (SIP-PVC) formwork concrete exposed to the ISO 834 fire curve. A systematic sampling ...
