LAHORE -UNS : Lahore has emerged as the world’s most polluted major city, recording an Air Quality Index (AQI) of 344, as hazardous smog continues to threaten public health. Doctors have advised residents to wear protective masks to reduce exposure to toxic air.
According to data recorded around 8am on Friday, Swiss air quality monitoring platform IQAir ranked Lahore first globally, placing its air quality in the hazardous category.
Fine particulate matter (PM2.5) was identified as the city’s primary pollutant, with concentrations reported at 57 times the World Health Organisation’s annual guideline.
These microscopic particles can penetrate deep into the lungs and enter the bloodstream, increasing the risk of heart disease, stroke, lung cancer and chronic respiratory illnesses.
Delhi Ranks Second in Global Pollution List
India’s capital, Delhi, ranked second among the world’s most polluted major cities, with an AQI of 244, classified as very unhealthy.
Senegal’s Dakar recorded an AQI of 184, while Mumbai and Kolkata in India registered readings of 179 and 172, respectively. Air quality in all three cities was categorised as unhealthy.
Iqbal Town Records Lahore’s Highest AQI
Pollution levels varied significantly across Lahore, with Iqbal Town recording the city’s highest AQI of 535.
Airwash on Bedian Road registered an AQI of 497, followed by Kahna at 446 and Defence Phase 5 at 360. Model Town recorded 350, while Barki Road reported an AQI of 253.
Seasonal Conditions Intensify Smog
Cooler weather during the autumn season can trap pollutants close to the ground, worsening Lahore’s smog problem. Major sources of pollution include crop-residue burning, vehicle emissions, industrial fumes and construction dust.
Delhi also experiences recurring severe smog, with authorities frequently linking the crisis to the burning of crop stubble in neighbouring Punjab and Haryana.
Children and Vulnerable Groups Face Greater Risks
Air pollution poses serious health risks, particularly for children and people with existing respiratory or cardiovascular conditions. UNICEF has warned that polluted air increases children’s vulnerability to acute respiratory infections.
A 2023 study also highlighted the long-term impact of air pollution on life expectancy, estimating reductions of more than five years in some parts of South Asia.
Severe smog episodes across the region regularly disrupt daily activities, leading to school closures, transport delays and increased pressure on healthcare services.
Residents are advised to limit prolonged outdoor exposure during periods of heavy pollution and follow local health and safety advisories.
