Diwali's Ghost: Lucknow Air Quality Still Suffers
11 Nov
Summary
- Lucknow's AQI remained in the moderate category post-Diwali.
- Air quality worsened steadily before Diwali and peaked after.
- Pollution stems from fireworks, vehicles, dust, and construction.
Lucknow's air quality, still impacted by Diwali celebrations, registered an AQI of 172 (moderate) on November 10th, a slight improvement from the 'poor' category reached post-festival. The city's air quality had progressively worsened in the days prior to Diwali, with the AQI rising from 188 on November 5th to a peak of 245 on November 9th.
Pollution levels were already high at several monitoring sites before Diwali, with Lalbagh recording 282 on November 7th. Firecracker emissions exacerbated the existing pollution from vehicle exhaust, road dust, and construction. Factors such as low wind speed and falling winter temperatures further contribute to pollutant dispersion difficulties.
Experts stress the importance of sustained dust control, stricter enforcement against polluting activities, and improved traffic management. These measures are crucial for addressing air quality issues throughout the year, rather than focusing solely on the festive period.
