The move comes two days after Swiss group IQAir rated Mumbai with an air quality index of 160, making it the second most polluted city in the world on Monday, second only to China's Beijing. A score between 151-200 is classed as"unhealthy", while a score below 100 is"healthy".
The BMC also said it would monitor air pollution emitted from plants belonging to state-owned refiners like Bharat Petroleum and Hindustan Petroleum, as well as privately owned Tata Power, all of whom have plants in Mumbai. New Delhi, which has been rated the world's most polluted capital by IQAir for consecutive years, recorded an AQI of 243 and is rated as"poor" by the CPCB.
