Residents in Delhi once again woke up to thick smog on Wednesday morning, with an AQI of 345 on October 22 at 5.30 am, falling in the ‘very poor’ category according to the Central Pollution Control Board (CPCB). This is the second consecutive day of deteriorating air quality in Delhi, after the national capital celebrated Diwali.
On Tuesday, October 21, many areas in Delhi recorded an AQI above 500 as NCR residents flouted the firecracker rules issued by the Supreme Court ahead of the festival. The 24-hour average air quality index (AQI) at 4 pm on Tuesday was 351 (very poor), up from 345 on Monday.
The air quality in Delhi has been an issue of concern every year due to stubble burning in neighbouring states, especially during the season of low wind speeds, leading to thick smog during the months of December and January.
