Lahore’s Air Quality Hits “Hazardous” Level of 329 AQI

Lahore is facing a severe public health crisis due to dense smog. The city’s air quality has been recorded at “hazardous” levels, making it one of the most polluted places in the world.

According to the Swiss air quality monitor IQAir, Lahore’s Air Quality Index (AQI) reached 329. This level is considered extremely dangerous for all residents.

The situation was even more critical earlier in the morning. The AQI shot up to 424, indicating an extreme pollution event. The level of PM2.5, the most harmful particulate matter, reached 287 micrograms per cubic meter. This is many times higher than the World Health Organisation’s safety guidelines.

Lahore is not alone in this regional crisis. Karachi ranked as the third most polluted city with an “unhealthy” AQI of 174. India’s capital, New Delhi, was ranked second with a “very unhealthy” AQI of 276.

The severe smog coincides with the start of winter. Cooler temperatures and stagnant winds trap pollutants close to the ground. Emissions from vehicles, factories, and crop burning contribute to the toxic mix. This creates a dense smog that lingers for weeks.
