Conversion of foliar residues of Sansevieria trifasciata into adsorbents: dye adsorption in continuous and discontinuous systems
(Springer Science + Business Media, 2022-09-04)
The study analyzed the potential of leaf powder prepared from the residual leaves of the species Sansevieria trifasciata, as a potential adsorbent for methylene blue (MB) removal. The equilibrium was reached fast for almost ...
Incidence of lung cancer and mortality among civil construction industry workers: A protocol for a systematic review and meta-analysis
(Corporación Universidad de la Costa, 2021-04-26)
The construction sector is one of the most stable growth industries in the world. However, many studies have suggested an association between occupational exposure in civil construction and lung cancer risk. Thus, this ...
Transforming shrub waste into a high-efficiency adsorbent: Application of Physalis peruvian chalice treated with strong acid to remove the 2,4-dichlorophenoxyacetic acid herbicide
(Corporación Universidad de la Costa, 2021)
In this study, the chalice generated from the production of the Physalis peruviana fruit was subjected to a treatment with sulfuric acid and applied in the adsorption of 2,4-Dichlorophenoxyacetic acid (2,4-D). The precursor, ...
Cassava bagasse as an alternative biosorbent to uptake methylene blue environmental pollutant from water
(Springer Science + Business Media, 2023-02-23)
Herein, the methylene blue (MB) biosorption from the agroindustrial residue (cassava bagasse) is reported. The cassava bagasse residue presented an irregular surface, anionic character, and low specific surface area. The ...
Acute exposure to C60 fullerene damages pulmonary mitochondrial function and mechanics
(Corporación Universidad de la Costa, 2020-11-28)
C60 fullerene (C60) nanoparticles, a nanomaterial widely used in technology, can offer risks to humans, overcome biological barriers, and deposit onto the lungs. However, data on its putative pulmonary burden are scanty. ...
Air quality and PM10-associated poly-aromatic hydrocarbons around the railway traffic area: statistical and air mass trajectory approaches
(Universidad de la Costa, 2019)
Diesel engine railway traffic causes atmosphere pollution due to the exhaust emission which may be harmful to the passengers as well as workers. In this study, the air quality and PM 10 concentrations were evaluated around ...
Composition and porosity study of original and restoration materials included in a coastal historical construction
(Universidad de la Costa, 2018-05-22)
The materials used for the building constructions can suffer during their life numerous deterioration processes induced by different anthropogenic and natural factors. For this reason, optimal restoration works are vitally ...
Comparative carbon emission assessments of recycled and natural aggregate concrete: Environmental influence of cement content
(Corporación Universidad de la Costa, 2021)
This work examines the environmental and geochemical impact of recycled aggregate concrete production with properties representative for structural applications. The environmental influence of cement content, aggregate ...
Application of Pb–Fe spinel-activated carbon for phenol removal from aqueous solutions: fixed-bed adsorption studies
(Springer Science + Business Media, 2023)
Fixed-bed studies for phenol uptake from water were carried out using a novel Pb–Fe spinel-activated carbon adsorbent. A characterization phase including TGA, FTIR, SEM, and BET analyses was performed for the developed ...
COVID-19 mortality and exposure to airborne PM2.5: a lag time correlation
(Corporación Universidad de la Costa, 2020-02-01)
COVID-19 has escalated into one of the most serious crises in the 21st Century. Given the rapid spread of SARS-CoV-2 and its high mortality rate, here we investigate the impact and relationship of airborne PM2.5 to COVID-19 ...
