Lahore second most polluted city in the world

Lahore: Lahore has once again become the second-most polluted city in the world as the smog threat continues to loom in the capital of Punjab province on Thursday.

According to the Air Quality Index (AQI), Doha has overtaken Lahore as the most polluted city in the world with a score of 188.

Experts claim that a rise in AQI over 100 is dangerous to the well-being of people.

Smog usually occurs in the middle of October. Its occurrence in the month of September sounded the alarm bell.
