India: Delhi surpasses Lahore as world’s most polluted city

On Friday, Delhi’s Air Quality Index (AQI) stood at 334, categorized as “hazardous”making it the most polluted major city globallyaccording to Swiss air quality monitoring group IQAir.

The Indian capital’s AQI was recorded to be higher than Lahore in Pakistan on Friday, which made it the most polluted city globally.

Quoting IQAir’s hourly data, Pakistani newspaper Dawn reported that on Friday Delhi’s AQI had dropped to 208 at 11.30 a.m. local time (0630 UTC). At the time, Lahore was ranked seventh among the world’s most polluted major cities, with an AQI of 155.

India’s official Central Pollution ​Control Board, however, recorded the AQI higher at 403 and ‌rated ⁠it “severe.”

The difference between the Indian and Swiss readings is caused by the fact that the two use different AQI scales and methodologies to calculate and categorize air pollution ​levels.

Visibility in Delhi is significantly impacted as a thick layer of smog has enveloped the city.

In many parts of northern India and Pakistan, pollution poses a seasonal problem as the ​cold, heavy air of ​winter traps vehicle emissions, construction dust and smoke from agricultural ​burning.
