The air quality in the national capital continues to remain a concern.
This is because it is gradually inching towards the ‘severe’ category.
The most identified of the culprit for this is the stubble-burning in neighbouring Punjab and Haryana.
It is in this context that the Central Pollution Control Board (CPCB) recorded the overall Air Quality Index of Delhi at 361 this morning, which falls in the ‘very poor’ category.
An AQI between 0 and 50 is considered “good”, 51 and 100 “satisfactory”, 101 and 200 “moderate”, 201 and 300 “poor”, 301 and 400 “very poor”, and 401 and 500 “severe”.
The CPCB however warns that the wind direction may change to northerly and north-westerly around November 7, the time of Diwali, which may lead to severe drop in Delhi’s air quality.
Stubble-burning is done by farmers and the resultant smoke takes the form of smog when it reaches Delhi and regions around it leading to a spike in air pollution.>
