After two days of slight relief, the pollution levels in Delhi increased on Friday. During the day, the smog reduced, making the sky clearer and allowing some sunlight. This provided a brief respite from the pollution during the day. However, smog was more prevalent in the morning and evening, causing the air quality to once again reach the severe category by evening.

According to the Air Quality Index (AQI) report for 264 cities across the country issued by the Central Pollution Control Board (CPCB), Delhi had the highest air index on Friday at 393. As a result, the air quality remained in the "very poor" category, making Delhi the most polluted city. Hajipur in Bihar was the second most polluted city, with an air index of 389.

Meanwhile, at the same time, the Swiss company's app, IQAir, reported Delhi's air index as 533 between 10:30 AM and 11:30 AM. After that, the air index gradually improved, and by 4:30 PM, IQAir reported the air index at 296.

However, by 7:00 PM, the app showed the air index at 340, categorizing the air quality as hazardous. According to CPCB standards, an air index of 340 is considered "very poor" quality.

Vehicle Emissions Contribute To 15% In Pollution

A report by the Decision Support System (DSS) of IITM Pune states that vehicle emissions contributed 15.16% to the pollution in Delhi, while smoke from industrial units accounted for 2.87%. On Thursday, smoke from stubble burning was responsible for 17.9% of the pollution in Delhi.

The levels of PM-10 and PM-2.5 in the atmosphere were 329.2 micrograms per cubic meter and 198.5 micrograms per cubic meter, respectively, which is over three times the standard limit. According to the CPCB, due to low wind speed, the air quality is expected to remain in the "very poor" category for the next three days as well.
