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 ...
Number Concentrations And Size Distributions Of Nanoparticles During The Use Of Hand Tools In Refurbishment Activities
(Journal Of Nanoparticle Research, 2018-09-17)
Hand tools, such as a sledgehammer, are widely used in refurbishment activities; nonetheless, there is very little knowledge on nanoparticle generation. We measured particle number size distributions (PSDs) and concentrations ...
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 ...
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 ...
Spatio-temporal variations of sulfur dioxide concentrations in industrial and urban area via a new statistical approach
(Universidad de la Costa, 2018-08-01)
Sulfur dioxide (SO2) is considered the most widespread pollutant that threatens environmental and human health. The purpose of this study is to propose a new method for evaluating the spatial variation of SO2 levels in the ...
