A Diwali Of Epic Proportions: Delhi Pollution This Year Was Highest Compared To Last Four Years

The article shows that this year’s Diwali in Delhi resulted in the worst air-pollution in four years, with post-festival fine-particulate (PM2.5) levels hitting a mean of about 488 µg/m³ and peaks over 1,400-1,700 µg/m³—far above the national safety standard of 60 µg/m³. It points out that many online real-time monitoring websites went offline during the worst hours, meaning the full extent of exposure is unclear. Also, despite the approval of so-called “green crackers”, the data indicate that fire-cracker emissions still drove large local spikes in pollution, especially under calm weather conditions with little wind to disperse pollutants. In short, celebration-time fireworks plus weather and monitoring failures combined to make this Diwali particularly hazardous for air quality in the city.
