Air pollution remains a major environmental and public health concern in India, primarily driven by rapid urbanization, industrialization, and vehicular emissions. This study presents a comprehensive data-driven analysis of air quality trends across major Indian cities using the Air Quality Index (AQI) and key pollutants, including Nitrogen Dioxide (NO₂), Nitric Oxide (NO), Ammonia (NH₃), and Carbon Monoxide (CO), over the period 2018–2024.The dataset, obtained from an open-source platform, was analyzed using statistical and visualization techniques in Microsoft Excel, including trend analysis and comparative evaluation. The findings reveal that AQI levels in most cities fall within the moderate to poor categories, with Delhi consistently exhibiting the highest pollution levels. Nitrogen-based pollutants, particularly NO₂, are identified as dominant contributors. Seasonal analysis indicates significantly higher pollution levels during winter due to atmospheric inversion conditions.The study emphasizes the need for stricter emission regulations, sustainable urban planning, and enhanced public awareness to mitigate air pollution and its health impacts.
