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 ...
In vitro genotoxic effect of secondary minerals crystallized in rocks from coal mine drainage
(Journal Of Hazardous Materials, 2018-03)
Coal processing generates a large volume of waste that can damage human health and the environment. Often these wastes produce acid drainage in which several minerals are crystallized (evaporites). This study aimed to ...
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 ...
Nanominerals and potentially hazardous elements from coal cleaning rejects of abandoned mines: Environmental impact and risk assessment
(Universidad de la Costa, 2017)
Soils around coal mining are important reservoir of hazardous elements (HEs), nanominerals, and ultrafine compounds. This research reports and discusses the soil concentrations of HEs (As, Cd, Cr, Cu, Ni, Pb, and Zn) in ...
Chemical and nano-mineralogical study for determining potential uses of legal Colombian gold mine sludge: Experimental evidence
(Chemosphere, 2018-01)
The present study is focused on the chemical and nano-mineralogical characterization of sludge from gold mine activities, in order to put forward diverse solution alternatives, where lack of knowledge has been found. The ...
Obese rats are more vulnerable to inflammation, genotoxicity and oxidative stress induced by coal dust inhalation than non-obese rats
(Ecotoxicology And Environmental Safety, 2018-08-26)
Obesity is an important nutritional disorder worldwide. Its association with environmental pollution may trigger an increase in oxidative stress and inflammatory parameters. Coal is a resource used throughout the world as ...
Hazardous elements and amorphous nanoparticles in historical estuary coal mining area
(Geoscience Frontiers, 2019)
In Brazil, intense coal exploitation activities have led to environmental deterioration, including soil mortification, water contamination, loss of ecosystem, and atmospheric contamination. In addition, considerable ...
Coal emissions adverse human health effects associated with ultrafine/nano-particles role and resultant engineering controls
(Environmental Research, 2017)
There are multiple elements which enable coal geochemistry: (1) boiler and pollution control system design parameters, (2) temperature of flue gas at collection point, (3) feed coal and also other fuels like petroleum coke, ...
Nanominerals and potentially hazardous elements from coal cleaning rejects of abandoned mines: Environmental impact and risk assessment
(Chemosphere, 2017)
Soils around coal mining are important reservoir of hazardous elements (HEs), nanominerals, and ultrafine compounds. This research reports and discusses the soil concentrations of HEs (As, Cd, Cr, Cu, Ni, Pb, and Zn) in ...
Multifaceted processes controlling the distribution of hazardous compounds in the spontaneous combustion of coal and the effect of these compounds on human health
(Environmental Research, 2018)
Pollution generated by hazardous elements and persistent organic compounds that affect coal fire is a major environmental concern because of its toxic nature, persistence, and potential risk to human health. The coal mining ...
