What are coal emissions?

coal emissions are most often from coal plants that result from coal combustion for electricity production. These emissions often come in the form of chemical compounds, with carbon dioxide, sulfur dioxide and nitrogen oxide. Coal emissions may also include carbon monoxide, mercury, arsenic and heavy foods such as lead, cadmium and uranium. All these have potentially negative environmental impacts.

The most common coal emissions is carbon dioxide. It is a tasteless odorless, which is a natural occurrence in the Earth's atmosphere and forms a small percentage of air. In larger quantities, such as the amount produced in coal -fired power plants, it is assumed that the gas can lean atmospheric balance and lead to the capture of further heat in the atmosphere of the greenhouse. This gas is not responsible for a greenhouse effect, at least not to a large extent, but can cause more located problems. It is the main cause of acid rain that can kill whole forests and fromdestroy the surfaces of buildings and vehicles. Although steps have been taken to reduce this gas from coal emissions in most countries, the problem is still the main in some parts of the world, especially in China.

Further main emissions of coal combustion are nitrogen oxide. This gas is responsible for creating ozone, which is useful at the upper levels of the atmosphere, but can be quite dangerous at lower levels where people live. At lower altitudes, ozone creates smog and can cause asthma attacks in those prone. Therefore, it is considered to be a risk of public health.

While these three gases make up most of coal emissions, there are more in smaller quantities. Mercury, Arsen and Hard to meet whole water systems can be poisoned, so water itself causes drinking or fish dangerous to human and animal consumption. Carbon monoxide can also cause respiratory problems or deteriorate heart conditions. As with someThere are ways to reduce any of these risks.

practices and cleaning agents can remove many coal emissions such as sulfur dioxide and nitrogen oxide, which is commonly found in coal. Scrubbers often use limestone to suck harmful gases, such as a fungus, usually turns them into a paste or powder that will not be released into the atmosphere. Other harmful materials can also be removed by a similar process. Despite progress in pure coal technology, there is still no cost -effective way of removing carbon dioxide.
