Nitrogen Oxides NOx

When fossil fuels like oil, coal and natural gas are burned a mixture of oxides of nitrogen, primarily nitric oxide (NO) and nitrogen dioxide (NO2), collectively termed NOx are released into the atmosphere. Nitrogen oxides like nitric oxide (NO) and nitrogen dioxide (NO2) can react in the air to produce ozone and other harmful pollutants that lead to smog. Nitrogen dioxide emissions can also be further oxidised in air to acid gases, which contribute to the production of acid rain.
