Evaluation of Soil Re-mineralizer from By-Product of Volcanic Rock Mining: Experimental Proof Using Black Oats and Maize Crops
(Universidad de la Costa, 2019-08-08)
This study was focused on physical, petrographical, mineralogical, and chemical characterization of a volcanic-rock mining by-product (dacite rock), as well as on greenhouse experiment with black oats and maize crops to ...
Chemical evaluation of by-products of the grape industry as potential agricultural fertilizers
(Journal Of Cleaner Production, 2019-06-20)
The grape industry, specifically the wine industry, is generating by-products rich in nutrients, which are underutilized and often end up being polluters of the environment. These byproducts are the bagasse, the stem and ...
Pollution from uncontrolled coal fires: Continuous gaseous emissions and nanoparticles from coal mines
(Journal of Cleaner Production, 2019-01-14)
In this investigation, the coal fires in different Colombian coal mines were studied using advanced
electron beam and X-ray diffraction techniques. The results were compared with information from highresolution transmission ...
Copper decreases associative learning and memory in Drosophila melanogaster
(Universidad de la Costa, 2019-11-24)
Copper is an essential element to all living organisms. Repeated use of metal-enriched chemicals, fertilizers, and organic substances may cause contamination at a large scale. Altered levels of Cu2+ may result in harmful ...
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 ...
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, ...
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 ...
Experimental method for investigation of impact of the addition of polymer fibers on drying shrinkage and cracking for concretes
(Structural Concrete, 2019-12-08)
This study presents an investigation of a fiber-reinforced concrete (FRC) with use
of fibers of polypropylene, polyvinyl alcohol, and recycled polyester in the amount
of 0.50%, seeking to analyze the impact of the fiber ...
Obesity associated with coal ash inhalation triggers systemic inflammation and oxidative damage in the hippocampus of rats
(Universidad de la Costa, 2019)
People with large amounts of adipose tissue are more vulnerable and more likely to develop diseases where oxidative stress and inflammation play a pivotal role, than persons with a healthy weight. Atmospheric contamination ...
Environmental evaluation and nano-mineralogical study of fresh and unsaturated weathered coal fly ashes
(Science of the Total Environment, 2019-01-24)
Coal combustion and the disposal of combustion wastes emit enormous quantities of nano-sized particles that
pose significant health concerns on exposure, particularly in unindustrialized countries. Samples of fresh ...
