Islamabad has managed to retain its ambient air quality during the monsoon season, keeping a lower pollutant ratio consistently.
The pollution level, with regards to particulate matter of 2.5 microns (PM2.5), has plunged below the permissible ratio of 35 micrograms per cubic meter (mg/m3), standing at 26.77 mg/m3. The 24-hour average of other environmental pollutants has gone below the permissible limits, making a healthy and ideal air quality.
However, the air quality was affected at times because of high vehicular emissions by automobiles running on the roads during busy hours.
The daily ambient air quality report of the capital city compiled by the Pakistan Environmental Protection Agency (PEPA) has revealed that the 24-hour average ratio of nitrogen dioxide (NO2) and sulfur dioxide (SO2) were 13.02 mg/m3 and 5.95 mg/m³ respectively.
Currently, they are recorded at 10.77 mg/m³ and 5.02 mg/m³ respectively against the National Environmental Quality Standards (NEQS) of 80 mg/m³ and 120 mg/m³.
However, the concentration of PM2.5 during the day and evening times are relatively high. Nevertheless, the overall air quality of Islamabad is healthy.
