Gulistan-e-Johar (157) and University Road (155) also surged into this dangerous zone. The data confirms a toxic wave has engulfed the city’s major residential areas.

The three-day forecast shows a sharp and promising drop back to “Moderate” levels. However, such a dramatic predicted improvement after a major spike is unusual.

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.
