India: Delhi surpasses Lahore as world's most polluted city
Delhi's Air Quality Index (AQI) was recorded to be higher than Lahore in Pakistan on Friday, which made it the most polluted city globally.
On Friday, November 14, Delhi, India surpassed Lahore, Pakistan to become the world's most polluted city, according to Swiss air quality monitoring group IQAir. Delhi's Air Quality Index (AQI) stood at 334, categorized as hazardous. Lahore's AQI was recorded at 155, placing it seventh among the most polluted major cities globally.
However, India's official Central Pollution Control Board recorded Delhi's AQI at 403, rating it as severe. The discrepancy in readings is due to the use of different AQI scales and methodologies by the two sources. Visibility in Delhi was severely impacted as a thick layer of smog enveloped the city.
