AQI surges post-Dasehra, sparks pollution concerns ahead of Diwali

The Air Quality Index (AQI) in the city surged from a normal level of around 150 to over 220 on the evening of Dasehra, indicating a rise in pollution ahead of Diwali.

Last year, too, Dasehra was celebrated in October and the average AQI for that month was 133. In comparison, the average AQI stood at 104 in October 2023, 134 in October 2022 and 101 in October 2021.

Sukhdev Singh, Environmental Engineer at the Punjab Pollution Control Board (PPCB), said that paddy harvesting has recently commenced in the state, beginning with the Majha region, followed by other areas. He added that initial reports suggest fewer farm fire incidents compared to previous years. However, he added that a more accurate comparison will be possible later in the month, once harvesting is in full swing.

As for Diwali, which is still 20 days away, the impact of firecracker-related pollution will become clearer in the coming weeks. Though the government permits only “green crackers”, smoke from these contribute to air pollution and can significantly affect air quality during the festive period.

Apart from stubble burning and firecrackers, other major contributors to pollution include construction activity and the increasing number of automobiles, especially diesel vehicles, on city roads. Traffic congestion and frequent jams result in prolonged idling of vehicles, releasing more pollutants into the air. This has led to the deterioration in Amritsar’s air quality.

Experts warn that the deteriorating AQI can pose serious health risks, especially for individuals with asthma, respiratory issues or heart conditions.

They added that rainfall can help clear the accumulated pollutants from the atmosphere, offering temporary relief from rising pollution levels.
