Oxides

of Nitrogen Oxides of Nitrogen (NOx) are a family of air pollutants produced by combustion of fuel. NOx compounds are formed when the nitrogen and oxygen atoms in the air combine with each other at high temperatures. NOx pollutants can have severe health and environmental impacts, such as acid rain, smog, and respiratory illness. They are also an important contributor to global warming. NOx can be reduced by more efficient fuel burning, fuel switching, and/or the use of air pollution control technologies. By controlling NOx levels, we can reduce the negative effects of air pollution and slow the rate of global warming.
