Pollution levels drop in Mumbai, AQI likely to remain moderate next 2 days: SAFAR

An AQI between 201 and 300 is categorised as ‘poor’ and between 301 and 400 is categorised as ‘very poor’ or red. The higher the AQI value, the greater the level of air pollution and health concerns.

Experts said the rise in pollution levels is due to two extreme weather conditions and the dust storm in the north-western region of the country. (Representational)
