Mumbai’s air quality continued to deteriorate on Thursday, with the city’s overall air quality index (AQI) rising to 137, according to the Centre’s SAMEER app. The AQI has shown a steady upward trend through the week—114 on Monday, 126 on Tuesday and 128 on Wednesday—indicating worsening pollution levels across the city.

While the AQI continues to remain in the ‘moderate’ category, poor air quality may cause breathing discomfort, particularly for people with asthma, lung disorders, and heart ailments.
