Delhi chokes as Diwali fireworks trigger severe air crisis

Delhi's air quality plummeted to dangerous levels following widespread firecracker bursting on Diwali eve, with environmental monitors capturing the rapid deterioration in atmospheric conditions across the city. According to monitoring data, 24 of the 54 measurement stations throughout Delhi registered air quality in the "severe" category, while the remaining 30 stations recorded readings classified as "very poor." The widespread pollution underscores the impact of festive season firecrackers on the national capital's already vulnerable air quality during winter months. Meteorological conditions typical of late autumn—characterized by slower wind speeds and temperature inversions—trap pollutants closer to the ground, exacerbating the effects of firecracker emissions. Health authorities have urged residents, particularly children, the elderly, and those with respiratory conditions, to remain indoors and limit outdoor exposure during periods of severe air pollution. The spike in pollution levels ahead of Diwali follows months of air quality challenges in Delhi, highlighting the ongoing struggle to manage the capital's environmental health during the festival season and winter transition period.
