Coal ash contains many toxic substances that may affect human health, if people are exposed to them above a certain concentration in the form of particulate matter.So it is necessary to avoid situations in which employees working in coal-fired power plants or public members living close to coal ash landfills will be exposed to high coal ash dust concentrations.

The Mpumalanga highveld in South Africa is the most polluted area in the world due to the mining industry and coal plant power stations [37] and the lowveld near the famous Kruger Park is under threat of new mine projects as well. [38] Illustration of air pollutants generated by U.S. power plants (includes both coal-fired and oil-fired plants)
Carbon capture and storage (CCS) can be used to capture carbon dioxide from the flue gas of coal power plants and bury it securely in an underground reservoir. Between 1972 and 2017, plans were made to add CCS to enough coal and gas power plants to sequester 161 million tonnes of CO 2 per year, but by 2021 98% of these plans had failed. [169]
The piles also create a fire hazard, with the potential to spontaneously ignite. Because most coal refuse harbors toxic components, it is not easily reclaimed by replanting with plants like beach grasses. [5] [6] Gob has about four times as much toxic mercury and more sulfur than typical coal. [1] Culm is the term for waste anthracite coal. [1]
The inedible fungus Daldinia concentrica is known by several common names, including King Alfred's cake, cramp balls, and coal fungus. It is a common, widespread saprotrophic sac fungus, living on dead and decaying wood. The fruit of this fungus is hemi-spherical, with a hard, friable, shiny black fruiting body 2 to 7 centimeters wide.
Poison Ivy, a well-known toxic plant common in Texas especially during the spring and summer, causes an itchy painful rash. This is caused by its sap that has a clear liquid called urushiol.
What does poison ivy look like? Poison ivy can grow as a vine or a small shrub, trailing along the ground or even climbing low plants, trees and poles.Look for three glossy leaflets. The common ...
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
