Residents of Lahore awoke to grey skies once again as the city topped the global pollution charts on Monday, grappling with thickening smog. According to IQAir, a Swiss air quality technology company, Lahore recorded an air quality index (AQI) of 532 this morning, maintaining its position as the world’s most polluted city for nearly a week.
The smog situation in Lahore has been deteriorating, with the AQI reaching an alarming 700 on Sunday, prompting the Punjab Environment Protection Department to issue a smog alert. IQAir classifies air quality as “hazardous” to health when the AQI exceeds 300, highlighting the severe pollution levels in the city.
Lahore faces significant pollution challenges each winter as falling temperatures trap construction dust, vehicle emissions, and smoke. The smog alert advises residents to take precautionary measures, such as monitoring air quality levels, keeping doors and windows closed, avoiding unnecessary outdoor activities, and wearing masks when outside.
In response to the hazardous conditions, all outdoor activities in schools across Punjab have been banned, and school timings have been adjusted. Traffic police have also cautioned commuters, particularly motorcyclists, to exercise care due to reduced visibility caused by the smog.
Neighboring New Delhi, India, retained its position as the second most polluted city, with an AQI of 268. Both Lahore and New Delhi frequently rank among the world’s most polluted cities during the winter months, as temperature inversions trap pollution close to the ground.
Karachi also featured among the top 10 most polluted cities today, with an AQI of 123, indicating “unhealthy” air quality for sensitive groups and individuals with allergies.
The Pakistan Meteorological Department has issued an advisory noting that foggy and smoggy conditions are common from November to mid-December as the country transitions into winter. Poor air quality poses a significant health threat, with citizens in polluted cities experiencing various medical issues, particularly respiratory problems.
