Delhi’s Air Quality Remains Poor, No Improvement Expected Soon

New Delhi, Oct 26. Delhi’s air quality has remained in the ‘poor’ category for the fourth consecutive day on Thursday, and any improvement is unlikely soon, according to monitoring agencies.

At 4 pm on Thursday, the city’s 24-hour average Air Quality Index (AQI) was recorded at 256, which is worse than the previous days’ readings of 243 and 220.

Neighboring areas also experienced similar conditions, with Ghaziabad at an average AQI of 235, Faridabad at 254, Gurugram at 230, Noida at 191, and Greater Noida at 260.

The Centre’s Air Quality Early Warning System predicts that Delhi’s air quality will continue to fluctuate between the ‘poor’ and ‘very poor’ categories for the next three to four days.

The government has launched a campaign to reduce vehicular pollution, which was previously put on hold due to concerns about its effectiveness.

A study conducted in 2019 revealed that keeping engines running at traffic signals can increase pollution levels by more than 9 percent.

Various studies conducted in recent years have shown that on-road vehicular exhaust emissions contribute to 9 to 38 percent of PM2.5 emissions in Delhi.

The drop in temperature and wind speed, along with emissions from firecrackers, paddy straw burning, and local sources of pollution, have caused Delhi’s air quality to deteriorate.

Peak pollution in Delhi occurs from November 1 to November 15, coinciding with the peak of stubble burning incidents in Punjab and Haryana.

The government has identified eight additional pollution hotspots in Delhi and will deploy special teams to monitor and control pollution sources in those areas.

To combat dust pollution, the government plans to use suppressant powder, which includes chemicals that bind fine dust particles together, preventing them from becoming airborne.

The Commission for Air Quality Management has directed authorities in the NCR to increase parking fees, promote the use of CNG or electric buses and metro trains, and implement other measures to control pollution levels.

The Delhi government has implemented a 15-point action plan to address air pollution during the winter season, focusing on dust pollution, vehicular emissions, and open burning of garbage.
