Mumbai Chokes: City's Air Quality Hits Unhealthy Levels

Mumbai's air quality has frequently entered unhealthy and severe categories, with AQI readings around 230-250 and some areas exceeding 290. Over the past week, air quality fluctuated sharply, reaching its worst on February 20 with an AQI of 318.

Experts identify a combination of factors driving this worsening pollution. Resuspended road and construction dust is a primary contributor, accounting for approximately 30% of PM10 and a significant portion of PM2.5. Vehicular emissions contribute around 16% of PM2.5 levels. Marine and secondary aerosols also play a role due to the city's coastal location, but human activities dominate.
