Gaseous pollutants (e.g., CO, SO2, NOx, VOCs, O3 etc.)

Fossil fuel combustion produces gaseous pollutants, causing variation in atmospheric composition. Nitrogen Oxide (NO) reacts actively with ozone (O3) or radicals in atmosphere forming nitrogen dioxide (NO2). In lower atmospheric layers, sun light acts as catalyst in reactions between NO2 and VOC (Volatile Organic compounds) to produce Ozone. Carbon Monoxide (CO) produced from partial fossil fuel combustion. Nitrogen oxides and carbon monoxide produced from sulfur based fossil fuel (coal and heavy oils) combustion.

Transportation and power plants the major volatile organic compound emission sources, which affects respiratory system as well as instigates hematological problems and cancer.
