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 ...
Adsorptive properties of highly porous activated carbon from açaí (Euterpe oleracea) towards the toxic herbicide atrazine
(Elsevier BV, 2023)
The great variety and possibilities of consumption of açaí pulp (Euterpe oleracea) have made its consumption increase considerably in recent years, mainly in Brazilian territory. The big problem is the generation of tons ...
Composite carbon materials from winery composted waste for the treatment of effluents contaminated with ketoprofen and 2-nitrophenol
(Corporación Universidad de la Costa, 2021)
The present work consisted of preparing and characterizing composite carbon materials (WRCC) from raw winery residues (WR) activated with zinc chloride to produce a carbon adsorbent. The WRCC was used for the adsorption ...
Exposure to nanometric pollutants in primary schools: Environmental implications
(Urban Climate, 2019-12-21)
School children are highly susceptible to chemicals in the atmosphere. Some studies have demonstrated that the pollution is related to respiratory problems and impaired cognitive development in children. In this context, ...
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 ...
River dynamics and nanopaticles formation: A comprehensive study on the nanoparticle geochemistry of suspended sediments in the Magdalena River, Caribbean Industrial Area
(Journal of Cleaner Production, 2019-12-21)
The coastal zones on continental shelves are the main channels for the distribution of fluvial-sourced
suspended sediments (SSs). In the current research, the monthly average amount of SS draining into
the Caribbean Sea ...
Eugenol mitigated acute lung but not spermatic toxicity of C60 fullerene emulsion in mice
(Corporación Universidad de la Costa, 2021)
C60 fullerene (C60) is a nano-pollutant that can damage the respiratory system. Eugenol exhibits significant anti-inflammatory and antioxidant properties. We aimed to investigate the time course of C60 emulsion-induced ...
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 ...
Study Of Coal Cleaning Rejects By FIB And Sample Preparation For HR-TEM: Mineral Surface Chemistry And Nanoparticle-Aggregation Control For Health Studies
(Journal Of Cleaner Production, 2018-04-05)
Nano-minerals and amorphous nanoparticles play a vital role in the contexts of human health and environmental sustainability. For instance, aerosols generated by the process of coal beneficiation adversely affect human ...
Surface chemistry of atmospheric nanoparticles during a haze episode in Beijing by TOF-SIMS
(Elsevier Inc., 2022-03-08)
The atmospheric aerosol particles have a potential heavy burden on environment, climate, and human health, which were closely related to the surface physicochemical properties. Time-of-flight secondary ion mass spectrometry ...
