Detailed explanation-1: -Most of the carbon monoxide pollution comes from burning fossil fuels in vehicles, factories, and power plants, but another major source is from burning wood or crop waste. Carbon monoxide is released from volcanoes and forest fires as well.
Detailed explanation-2: -Emissions from burning coal 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.
Detailed explanation-3: -Nitrogen Oxides (NOx) Oxides of nitrogen (NOx) are a class of pollutants formed when fuel is burned at a very high temperature (above 1200 °F), such as in automobiles and power plants. For air pollution purposes, it is composed primarily of nitric oxide (NO), nitrogen dioxide (NO2) and other oxides of nitrogen.
Detailed explanation-4: -What are indoor emissions from the household combustion of coal? Burning coal inside the home for the purposes of heating or cooking produces particulate and gas emissions that may contain a number of harmful chemicals, such as benzene, carbon monoxide, formaldehyde, and polycyclic aromatic hydrocarbons.
