LAHORE: The city’s Air Quality Index (AQI) once again turned very unhealthy on Saturday as the US AQI highlighted a score hovering between 208 to 320.
Lahore is ranked as one of the most atmospherically-polluted cities of the world, an official source in the environment department told Dawn.
Meanwhile, heavy fog blanketed major cities of Punjab, affecting road and air traffic as motorways were closed and several flights cancelled because of low visibility levels.
However, the motorways and airports resumed the operations around 11am after the visibility improved considerably.
