Air quality in Mumbai remains a serious concern with the current readings exceeding safe limits. According to the Central Pollution Control Board's SAMEER app, the Air Quality Index of Mumbai stands at 113, falling within the 'moderate' category.  The AQI reading is indicative of PM2.5 concentrations exceeding the WHO recommended limit by nearly 3.1 times.

The main causes of air pollution in Mumbai are waste burning, industrial activity, construction dust, and vehicle emissions. These sources emit fine particulate matter (PM2.5 and PM10) into the atmosphere, which has the ability to enter the lungs deeply and result in heart problems, respiratory disorders, and other health issues.
