Delhi chokes on worst pre-Diwali air in decade as pollution peaks

Delhi's air quality deteriorated to decade-high pollution levels as the festival season approached, with the Air Quality Index reaching hazardous thresholds across multiple monitoring stations in the National Capital Region. The deterioration represents the worst pre-Diwali air conditions recorded in the past ten years, raising health concerns among residents and triggering official advisories.

Meteorological conditions, including reduced wind speeds and temperature inversions typical of early winter, have trapped pollutants in the region's atmosphere. Contributing factors include vehicular emissions, construction activities, and agricultural burning in neighboring states—practices that intensify during the festival season.

Authorities issued guidelines recommending reduced outdoor activities, particularly for vulnerable populations including children, the elderly, and those with respiratory conditions. Schools in several areas activated air quality contingency protocols, while health officials urged residents to monitor air quality indices before planning outdoor Diwali celebrations.

The pollution crisis underscores persistent challenges facing Delhi's air management despite ongoing efforts to implement emission control measures and monitor industrial compliance. Environmental agencies have appealed for public cooperation in reducing artificial emissions during the festival period.
