Dust containing these salts can enter the air from mining deposits of ores that contain mercury. Emissions of both elemental or inorganic mercury can occur from coal-fired power plants, burning of municipal and medical waste, and from factories that use mercury.
Does coal contain mercury?
Coal naturally contains mercury, a neurotoxin that can damage the nervous system, the brain and other organs. When we burn coal, that mercury gets released into the atmosphere and ultimately rains down into bodies of water. … Therefore, coal is a massive threat to public health.
How much mercury is in coal?
The concentration of mercury in coal samples from the U.S. Geological Survey’s COALQUAL database averages 0.17 ppm for in-ground coal in the conterminous United States. Mean values range from 0.07 ppm for coal samples from the Uinta region to 0.24 ppm for samples from the northern Appalachian coal-producing region.
What pollution does coal cause?
Several principal emissions result from coal combustion: Sulfur dioxide (SO2), which contributes to acid rain and respiratory illnesses. Nitrogen oxides (NOx), which contribute to smog and respiratory illnesses. Particulates, which contribute to smog, haze, and respiratory illnesses and lung disease.
Is mercury a pollutant?
Mercury (Hg) is a global pollutant that affects human and ecosystem health.
Is Mercury illegal?
Exposure to elemental mercury can damage human health because it is toxic to the kidneys and the nervous system. … Mercury use is legal in certain industrial processes, but its handling is highly regulated and monitored.
Where do you find mercury in everyday life?
List of Common Consumer Products that Contain Mercury

Does mercury stay in your body forever?
Mercury does not stay in the body forever. It takes about six months to a year to leave the bloodstream once exposure stops. Some researchers think mercury can permanently damage the nervous system in children.
What is the most toxic form of mercury?
The toxic effects of mercury depend on its chemical form and the route of exposure. Methylmercury [CH3Hg] is the most toxic form. It affects the immune system, alters genetic and enzyme systems, and damages the nervous system, including coordination and the senses of touch, taste, and sight.
Does burning coal produce mercury waste?
Human activities, however, are responsible for much of the mercury that is released into the environment. The burning of coal, oil and wood as fuel can cause mercury to become airborne, as can burning wastes that contain mercury.
Why we should stop using coal?
As of 2010, coal accounted for 43% of global greenhouse gas emissions from fuel combustion. Simply put, to solve the climate crisis we must stop burning coal. Job number one is retiring old coal plants. … Carbon dioxide (CO2) is the main greenhouse gas, and is the leading cause of global warming.
Does coal cause global warming?
Coal impacts: global warming
Chemically, coal is mostly carbon, which, when burned, reacts with oxygen in the air to produce carbon dioxide, a heat-trapping gas. When released into the atmosphere, carbon dioxide works like a blanket, warming the earth above normal limits.
Why coal is bad for the environment?
The burning of fossil fuels releases greenhouse gases into the atmosphere, increasing levels of CO2 and other gasses, trapping heat, and contributing to global climate change. … Coal-fired power plants release more greenhouse gases per unit of energy produced than any other electricity source (1).
What is the main source of mercury?
Natural sources of mercury include volcanoes, forest fires, cannabar (ore) and fossil fuels such as coal and petroleum. Levels of mercury in the environment are increasing due to discharge from hydroelectric, mining, pulp, and paper industries.
Where is mercury pollution found?
Mercury occurs naturally in the earth’s crust, but human activities, such as mining and fossil fuel combustion, have led to widespread global mercury pollution. Mercury emitted into the air eventually settles into water or onto land where it can be washed into water.
How can we reduce mercury pollution?
Prevent mercury pollution
Make sure that you recycle mercury-containing products and bulk mercury; households can contact the local household hazardous waste collection program. A few products require mercury to function, such as fluorescent and high-intensity-discharge lighting.
