While temperatures have remained largely stable in recent days, air pollution levels have continued to fluctuate, raising health concerns among residents.
Data from the Sameer app indicated that the overall air quality index (AQI) in Mumbai stood at 136 on Wednesday, placing it in the ‘moderate’ category. Pollution levels varied significantly across locations, with Bandra-Kurla Complex recording an AQI of 147, Borivali East 131, Byculla 154, Andheri East 130, Chembur 127, Colaba 122, and Kandivali East 149.
