Lahore continues to be ranked world’s most polluted city
Punjab’s capital Lahore was once again ranked the most polluted city in the world with hazardous air quality conditions prevailing on Wednesday.
The severity of the situation was evident in the early hours when the Air Quality Index (AQI) reached 451, as reported by www.iqair.com, a global air quality monitoring platform. It is important to note that air is considered safe to breathe when the AQI is below 50.
The AQI is calculated on the basis of five categories of pollution: ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
