Impact of diverse eco-friendly zones on the Air Quality Index (AQI) in Metropolitan City, India
This study examines the air quality pattern by studying Air Quality Index (AQI) in Bengaluru Urban, a metropolitan city in India, using the data from the year September 2022 to May 2025. AQI levels are analysed across four urban regions – North, South, East and West and across residential and industrial areas using statistical data analysis and visualization techniques. The results highlights that industrial areas have consistently exhibiting very high AQI levels than residential areas, which indicating the dominant influence of industrial activity and traffic emissions. Further zone wise analysis shows that the west and south zones of Bengaluru urban were experiencing poorer air quality and is affected, while the east zone shows comparatively less air pollution levels. The results provide the solid necessity for location specific policy interventions. In addition, several monitoring stations also showed persistent pollution hotspots, evidencing strong localised variations in exposure. These spatial patterns provide a strong evidence base for zone-specific and hotspot-based air quality management strategies in Bengaluru. The study contributes to urban environmental governance by finding priority areas for targeted intervention. Future work will extend this analysis by integrating advanced time series models to forecast air pollution trends across the city’s monitoring system.
