This type of smog is created when nitrogen oxides and volatile organic compounds, generated largely by vehicle exhaust, but also by factory emissions, are released into the air and react to sunlight.

Smog is produced by a set of complex photochemical reactions involving volatile organic compounds (VOCs), nitrogen oxides and sunlight, which form ground-level ozone. Smog-forming pollutants ...

The one we experience these days is most likely to be "photochemical smog". This happens when the nitrogen oxides in the air -- ejected by high volume of traffic and industrial factories -- reacts ...

There are two primary types of smog: Photochemical Smog: It is formed when the sun interacts with nitrogen oxides and volatile organic compounds in the atmosphere. It produces ground ozone ...

They react in the atmosphere with sunlight to form secondary pollutants. Photochemical smog is formed by the combination of primary emissions and secondary pollutants. In warmer, sunnier weather ...

Chances are you have been exposed to photochemical smog, a form of air pollution that traces its history to the 1970s when Japan's rapid industrial growth was not only driving an economic boom but ...
