What happened: Pakistan’s Environmental Protection Agency report on 22nd December revealed that Islamabad’s air quality reached the highest due to hazardous vehicle emissions. EPA has further highlighted that Islamabad’s air quality is dangerous for all age groups and the citizens should avoid outdoor travelling. Details: Environmental Protection Agency’s spokesperson is quoted by a publication saying that the primary reason for air pollution in the capital was the large number of vehicles entering Islamabad on a day-to-day basis. Another contributor to the worsening air quality in the capital was the smoke emission from the steel manufacturing units. Also: The prolonged dry weather in Islamabad is also one of the contributors to smog as Islamabad recorded PM 2.5 at 198.96 and the eight hour average on the 22nd December was 280.3. On the other hand, Lahore has been facing the problem of worsening air quality as the provincial capital recorded its all-time high air quality index during December.
