Over time, the extra work and pressure can stiffen blood vessels, leading to high blood pressure, heart attack, and stroke. It can also lead to heart failure. There is also some evidence that too much salt can damage the heart, aorta, and kidneys without increasing blood pressure, and that it may be bad for bones, too. High blood pressure is a leading cause of cardiovascular disease.
CMM is a mixture of methane & air released during the process of coal mining and must be vented for safety reasons. Methane has significant effects as a greenhouse gas being 21 times higher than that of carbon dioxide, therefore its capture and use in gas engines has significant environmental benefits.
Coal is mostly carbon. During complete combustion, carbon is oxidised to carbon dioxide: carbon + oxygen â carbon dioxide. Carbon dioxide is a greenhouse gas greenhouse gases: the gases responsible for the global warming-carbon dioxide, methane, nitrous oxide and CFCs.Increasing concentrations of it in the atmosphere contribute to global warming. Hydrocarbon fuels contain carbon and hydrogen.xidation also means a loss of electrons. to water, but carbon monoxide forms instead of carbon dioxide. Carbon monoxide is a toxic gas, so adequate ventilation is important when burning fuels. Solid particles (particulates) are also released. These contain carbon and are seen as soot or smoke.
