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
