Lahore which has a hopeless AQI level of 445 is the only city with AQI levels marked as “hazardous”. It is followed by Delhi and Kolkata of India and Dhaka of Bangladesh with AQI levels of 262, 233, and 228 respectively— all under the “very unhealthy” zone.
Karachi, the largest city in Pakistan both in terms of population & area, is also on the list of the top 10 worst cities in the world in terms of air quality, but its AQI levels stand at 185 in the “unhealthy” zone.
According to the IQ Air report, air pollution in Lahore is caused by a combination of vehicle and industrial emissions, smoke from brick kilns, the burning of crop residue and general waste, and dust from construction sites. Other factors of air pollution include large-scale losses of trees to build new roads and buildings. Plus the air quality in Lahore usually worsens during the winter season due to temperature inversion, which means pollutants remain trapped in the air for longer.
