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.

Newly built coal-fired power plants can be made to immediately use gasification of the coal prior to combustion. This makes it much easier to separate off the CO 2 from the exhaust fumes, making the process cheaper. This gasification process is done in new coal-burning power plants such as the coal-burning power plant at Tianjin, called "GreenGen".
Mercury emissions from coal-fired power plants can fall back onto the land and water in rain, and then be converted into methylmercury by bacteria. [62] Through biomagnification, this mercury can then reach dangerously high levels in fish. [63] More than half of atmospheric mercury comes from coal-fired power plants. [64]
The coal plants are mostly base-load plants with typical utilisation rates of 50% to 60% (relating to full load hours). Utility companies have shut down and retired aging coal-fired power plants following the Environmental Protection Agency's (EPA) implementation of the Cross-State Air Pollution Rule (CSAP).
China's pollution problems are well known. Recently the city of Harbin saw levels of fine particulate matter 40 times the recommended levels by the World Health Organization. While coal is a big ...
Supreme Court rejects a series of emergency appeals from Republican-led states and the coal and electric power industries. EPA can force coal-fired power plants to drastically cut carbon pollution ...
The Kingston Fossil Plant Spill was an environmental and industrial disaster that occurred on December 22, 2008, when a dike ruptured at a coal ash pond at the Tennessee Valley Authority's Kingston Fossil Plant in Roane County, Tennessee, releasing 1.1 billion US gallons (4.2 million cubic metres) of coal fly ash slurry.
Power plant emissions of mercury in the United States are thought to be about 50 tons per year in 2003, and several hundred tons per year in China. Power plant designers can fit equipment to power stations to reduce emissions. Coal mining practices in the United States have also included strip mining and removing mountain tops. Mill tailings ...
