Do you know about SMOG?

The world of big and large cities seems glamorous from outside but however the sight you have within might be so hazy and obscure that you can’t even see the horizon. This might be because of the smoke or the fog which is nonetheless called as SMOG.

Smog is a type of air pollution which is caused by the tiny particles present in the air. The word smog derives from the mixture of smoke and fog. Smog is formed by the particulate matter present in the atmosphere mainly ground level ozone and fine particles emitted through the fossil fuels from automobiles, factories and power plants. This yellowish or blackish fog can also be described as the mixture of various gases, dust and vapours available in the atmosphere. It not only creates the haze or reduces the visibility but also becomes the root cause for many of the bronchial and heart problems as it makes breathing difficult.

How Smog is formed?

Smog is formed when sunlight and its heat react with the gases and fine particles released into the atmosphere through burnt fuels. The complex photochemical reactions between the precursors like volatile organic compounds, sulphur dioxide and nitrogen oxides release the ground level ozone and fine particles in the air.
