Two Indian cities have joined the national capital, New Delhi, on the list of the world’s top 10 most polluted cities, with smoke heavy in the air a day after revellers let loose with firecrackers for Diwali, the annual Hindu festival of light.
New Delhi took the top spot, as it often does. It had an air quality index (AQI) figure of 407 on Monday, falling in the “hazardous” category, according to Swiss group IQAir.
Financial capital Mumbai came in sixth with an AQI of 157, while Kolkata in the east was seventh with an AQI of 154.
An AQI level of 400-500 affects healthy people and is dangerous to those with existing diseases, while a level of 150-200 brings discomfort to people with asthma, lung and heart problems. Levels of 0-50 are considered good.
A thick layer of smog had started accumulating in New Delhi from Sunday night, sending its AQI to an alarming 680 a little after midnight.
Every year, authorities ban firecrackers in the capital, but those bans rarely appear to be enforced.
Parliamentarian Saket Gokhale posted a letter on X, formerly known as Twitter, in which he asked the local police for details on the number of cases of the use of firecrackers and the action taken against the perpetrators.
