As Diwali comes nearer, the air quality in the national capital remains in ‘very poor’ category with Air Quality Index (AQI) touching 370 on Friday. 

Despite a slew of measures that were implemented in the Capital ahead of Diwali when a spike in pollution was expected to hit the city, the AQI indicates at failed results. 

According to the Central Pollution Control Board (CPCB) the PM2.5 level was recorded at 210. Fine particulates can be a matter of more serious health concern than PM10 (particles in the air with a diameter of less than 10 micrometres). Four areas in Delhi recorded “severe” air quality while 29 areas recorded “very poor” air quality. 

Although cases of stubble burning have reduced now, but government agencies like System of Air Quality and Weather Forecasting And Research (SAFAR) maintained that the air quality would stay as ‘very poor’ due to the westerlies disturbances. 

“This is mainly due to weather conditions such as stubble contribution is marginal now. The moisture intrusion over Delhi and surrounding regions due to the westerlies disturbances will increase with effect from November 4 to enhanced holding capacity of atmosphere resulting in increase in PM2.5 levels,” the SAFAR website said.

“Winds are calm and it is favourable for stagnation of pollution. Although upper air winds where transport takes place are from stubble burning site but speed and magnitude is low and hence unlikely to impact Delhi air quality significantly,” it added.”

The civic authorities have also stayed ban on any kind of construction after the increase in level of pollutants.
