Delhi’s AQI Experiences Sharp Drop to Lowest October Level in Three Years
Delhi’s air quality index (AQI) in October saw a dramatic and unexpected improvement, dropping from a high to moderate levels—the lowest in three years for the month. This improvement occurred without rainfall, puzzling experts. The government attributes the better air quality to stricter enforcement, anti-smog guns, and thorough road cleaning, with some meteorological factors also influencing the change.
In October, Delhi's air quality experienced a significant and sudden improvement, recording its lowest AQI reading for the month in three years. Despite no rainfall, which often helps clear pollutants, experts remain uncertain about the full range of causes behind this unexpected drop. The government credits this improvement mainly to the effectiveness of enforcement teams actively managing pollution sources, the deployment of anti-smog guns that spray water to settle dust particles, and enhanced road sweeping efforts. Additionally, meteorological factors such as shifts in wind patterns and lower humidity contributed to dispersing pollutants, but these alone do not entirely explain the change. This multifaceted improvement presents a positive but puzzling environmental development for the city, prompting ongoing investigations to fully understand all contributing factors. The AQI drop indicates a notable shift towards better air quality, benefiting residents during a typically pollution-heavy period in Delhi’s calendar.
