Representational image

While there remains only a marginal improvement in the AQI of Delhi NCR, the major pollutants are slowly shifting from PM2.5 to PM10. It is important to take note of the huge difference between the AQI of the northern and the southern states of the country, with the latter showing a much better AQI as compared to the north.

Pollution Watch brings you the measure of Air Quality Indiex (AQI) in major cities across the country.

The AQI is measured by taking into account the PM (particulate matter). The pollution of a place is measured either in PM10 or PM2.5, depending on which particle is more dominant in the air in that place.

PM10 is the particle which is 10 micrometers or less in diameter and PM2.5 is the finer particle with a diameter measuring 2.5 micrometers or less.

PM2.5 is considered more harmful since it is finer and can travel more deeply into the lungs and cause very harmful effects. These tiny particles in the air reduce visibility and cause the air to appear hazy when their levels are high.
