Explanation:

The three major air pollutants are Carbon monoxide (CO), Particulate Matter (PM10, and PM2.5) and Ozone (O3).

1. Carbon monoxide is colorless, odourless gas, mainly produced due to incomplete combustion of fossil fuels. CO has a great affinity for blood oxygen carrier, haemoglobin, forming carboxyhemoglobin. This substance is very harmful for humans. It can cause headache, dizziness, weakness, neusea, vomiting, and finally loss of consciousness.

2. Particulate matter (PM) are particles of certain size which when enter our body can cause a lot of damage. PMs are linked with pulmonary and cardiac disease. It initiates a lot of lungs and heart diseases. Depending upon the level of exposure PMs can also cause premature deaths.

3. Ozone is an allotrope of oxygen generally found in upper atmosphere in the stratosphere, protects us from harmful ultra violet rays of the sun. The ground level ozone (GLO) are harmful to human health. Ozone can cause risk of respiratory disease like Asthma.
