Firecrackers responsible for bulk of Delhi pollution spike post-Diwali

New estimates reveal that firecrackers were the primary driver of air pollution in Delhi in the days following Diwali, with analyses indicating the pyrotechnics contributed roughly 80 percent of the recorded pollution increase across the capital.

The findings highlight the significant role festive firecracker displays play in deteriorating air quality during India's most celebrated festival. As residents discharge firecrackers to mark Diwali, the cumulative emissions create a sharp spike in particulate matter and other pollutants, overwhelming the city's atmosphere.

Delhis air quality typically undergoes dramatic swings during the Diwali period, with pollution levels often reaching hazardous ranges within hours of peak firecracker usage. The capital has struggled with severe air pollution for years, compounded by seasonal factors including crop burning in neighboring states and vehicular emissions.

Environmental experts have consistently flagged firecrackers as a controllable pollution source, urging citizens to adopt eco-friendly celebration alternatives. The estimates provide quantifiable evidence of the practice's environmental cost, adding weight to ongoing campaigns for reduced firecracker consumption during festival seasons across India's major urban centers.
