Lahore, the capital of Punjab, once again topped global pollution charts on Monday, recording an alarming air quality index (AQI) of 532, as reported by IQAir, a Swiss air quality monitoring agency. This marks nearly a week with Lahore listed as the world’s most polluted city, signaling a deepening smog crisis.

Winter Smog Traps Pollutants, Worsening Air Quality

As winter temperatures drop, Lahore’s AQI has risen dramatically due to pollutants such as construction dust, vehicle emissions, and industrial smoke being trapped close to the ground. The Punjab Environment Protection Department recently issued a smog alert after AQI levels surged to 700, urging citizens to exercise extreme caution.

Safety Measures for Citizens Amid Hazardous Conditions

The smog alert advises residents to stay indoors, keep doors and windows closed, wear masks if stepping outside, and avoid unnecessary outdoor activities. School timings have been adjusted, and outdoor activities in educational institutions have been banned for student safety.

Traffic Authorities Warn of Low Visibility Hazards

Lahore’s thick smog has led traffic authorities to advise motorcyclists and drivers to proceed with caution, as reduced visibility creates challenging commuting conditions.

New Delhi and Karachi Also Face Severe Air Quality Issues

Neighbouring New Delhi retained its spot as the second-most polluted city globally, with an AQI of 268. Karachi ranked among the top 10 polluted cities with an AQI of 123, a level classified as “unhealthy” for sensitive groups.

Health Impacts of South Asia’s Poor Air Quality

The Pakistan Meteorological Department expects foggy and smoggy conditions to persist from November to mid-December. Poor air quality poses severe health risks in South Asia, with a recent report indicating that rising pollution could reduce life expectancy by more than five years in the region.
