India: Delhi surpasses Lahore as world’s most polluted city
Delhi recorded the world’s highest air pollution among major cities on Friday, surpassing Lahore, Pakistan, according to IQAir. The hazardous smog has reduced visibility and highlights the seasonal pollution affecting northern India and Pakistan.
IQAir reported Delhi’s Air Quality Index at 334, while India’s Central Pollution Control Board recorded 403 and classified it as severe. The readings differ because the organisations use separate AQI scales and methods; at 11.30 am, IQAir data put Delhi at 208 and Lahore at 155. Winter conditions trap vehicle emissions, construction dust and smoke from agricultural burning.
In short
- Delhi ranked as the most polluted major city on Friday.
- IQAir recorded an AQI of 334; India’s official reading was 403.
- Winter air traps emissions, dust and agricultural smoke.
