On Friday, Delhi's pollution board claimed that the air quality index did not show any significant change this Diwali, even after many flouted pollution norms.
The Delhi Pollution Control Committee released a report stating that the PM2.5 levels decreased by 4 per cent as compared to Diwali last year, reported PTI. While the PM10 levels, consisting of particulate matter that is 10 micrometres or less in diameter, increased by 11 per cent.
PM2.5 are fine particulate matter that can be inhaled which can pose a greater health risk.
However, data by CPCB claimed that Delhi recorded its most polluted Diwali in three years. On Thursday, the city's 24-hour average Air Quality Index (AQI) was recorded at 330, compared to 218 in 2023 and 312 in 2022.
According to the report, most monitoring stations in Delhi mirrored similar pollution levels with 37 of the 39 reporting air quality in the 'very poor' category. However, various pollution control efforts implemented across the city avoided a severe spike, it added.
