By exploring the impacts of coal-to-gas policies on representative coal and natural gas power plants in four countries (China, Germany, India, and the United States), Tanaka et al. (2019) found that reducing CO 2 emissions by switching from coal to natural gas power plants is a key strategy for supporting climate stabilization.

Nigeria is blessed with abundant mineral resources such as iron ore, cassiterite, columbite, lead and zinc, kaolin, limestone, marble, diatomite, gold, gemstones, talc, bitumen, coal, petroleum and natural gas at different states of the country. Their extraction and processing activities are of different scales of intensity.
This article reviews evidence for the public health impacts of coal across the extraction, processing, use, and waste disposal continuum. Surface coal mining and processing impose public health risks on residential communities through air and water pollution. Burning coal in power plants emits more nitrogen oxides, sulfur dioxide, particulate matter, and heavy …

Trucks, rail and barges used to transport coal all affect air and water quality. As well as the environmental and health impacts from blowing coal dust, there is also the air pollution from the vehicles themselves.x Coal-fired power generation Coal-fired power plants emit more than 60 different hazardous air pollutants. Yet, despite billions of

4 Conclusion. Mining has a tremendous impact on the economic, social, and environmental fabric of the surrounding area. Mining activities contribute to economic development in the area, but they also degrade the land, causing ecological and socio-economic issues. Mining harms the ecology as a whole.
Specifically for iron-containing aerosol particles, ferric iron (Fe(iii)) can drive sulfate formation from HSO 3 − either by a homogeneous (i.e., solution phase) or heterogeneous (i.e., at the solid–water interface) catalytic pathway, according to reactions . 15 For homogeneous catalysis, Fe(iii) in mineral particles must first dissolve ...
The future of global coal use is a study in contradictions, although the long-term trajectory signals a decline. In the United. States, coal consumption in the last 12 y ears has declined from ...
The first part will deal with the health impacts of coal combustion. The second part will describe a severe health problem believed to be caused or exacerbated by the organic moieties leached by water from coal aquifers. ... Others report that Pennsylvania coal has a higher content of surface available iron and generates more reactive oxygen ...
4. Impact of coal mine on the health of workers. Mining of coal has various effects on the health of the coal miners. The factors that modify these impacts of the coal mining on the health of people are the following: the way it is mined, the emission control in the place and the measures used to control its impact. (Selvey, L., 2014).
During the period of the industrial revolution, as demand for coal soared thanks to iron and steam, as the technology to produce coal improved and the ability to move it increased, coal experienced a massive escalation.From …
There are numerous damaging environmental impacts of coal that occur through its mining, preparation, combustion, waste storage, and transport. This article provides an overview. Acid mine drainage (AMD) refers to the outflow of acidic water from coal mines or metal mines, often abandoned mines where ore- or coal mining activities have exposed rocks containing the …
Acid mine drainage (AMD) refers to the outflow of acidic water from coal mines or metal mines, often abandoned mines where ore- or coal mining activities have exposed rocks containing the sulphur-bearing mineral pyrite.Pyrite reacts with air and water to form sulphuric acid and dissolved iron, and as water washes through mines, this compound forms a dilute acid, which can wash …

The recent resurgence of CWP globally with examination of cases in the United States suggesting a potential but inconclusive role of Fe(II)-sulfide minerals. To obtain a better understanding of Australian coals, the existence and potential adverse impacts of iron minerals were examined using 24 representative Australian coal samples.
Climate change has been shown to have significant impacts on both power demands and power supplies. However, empical assessments on the latter are still limited. Using monthly data collected from 461 coal-fired power plants in China during the period from 2012 to 2014, this paper explores the influences of a
