Provincial capital of Punjab has been declared the most polluted city globally after the city’s Air Quality Index (AQI) went above 360.

The Air Quality Index data was released on Sunday and put Lahore on the list of the most polluted cities in the world while Karachi came in seventh.

On the other hand, PM2.5 concentration in Lahore air is currently 62.9 times above the WHO annual air quality guideline value. Residents choking in acrid smog pleaded with officials to take action.

Air pollution has worsened in Pakistan in recent years, as a mixture of low-grade diesel fumes, smoke from seasonal crop burn off, and colder winter temperatures coalesce into stagnant clouds of smog.

Lahore, a bustling megacity of more than 11 million people in Punjab province near the border with India, consistently ranks among the worst cities in the world for air pollution.

In recent years residents have built their own air purifiers and taken out lawsuits against government officials in desperate bids to clean the air — but authorities have been slow to act.

What causes air pollution in Lahore? 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.

Winter air pollution is worse due to temperature inversion, which results in a layer of warm air that is prevented from rising trapping air pollutants.

Meanwhile, There is very little the department can do to control the situation, except for dealing with the “hot spots” of pollution, the official continues.

The industrial areas and their operations are under the microscope now.The department has already instructed its field force to concentrate on the industrial operations, especially during the night.

Normally, the industry, especially in northern Lahore, uses substandard and highly polluting fuels during the night.
