DHA Phase 5 (153) and North Nazimabad (135) also showed significant deterioration. The data confirms a clear reversal of the minor improvements seen earlier in the week.
The three-day forecast predicts these elevated, hazardous levels will persist. Air quality is expected to remain in the “Unhealthy” range through the weekend.
Yasir Husain, director of the Climate Action Center in Karachi, described the city’s air as stagnant and heavily polluted.
Husain attributed the worsening air quality to the large number of petrol- and diesel-powered vehicles on Karachi’s roads, along with dust from ongoing construction activities across major areas.
He urged all residents, especially minors, to wear face masks when going outdoors to reduce exposure to harmful PM2.5 particles.
