The air quality of the federal capital was recorded healthy for second consecutive day on Thursday amid strong gusty winds blowing in the twin cities of Islamabad and Rawalpindi that helped in reducing suspended particulate matter in the atmosphere.
A Pakistan Environmental Protection Agency (Pak-EPA) official told media that the eight hours average ratio of particulate matter of 2.5 microns (PM2.5) was recorded below permissible limits of 35 microgrammes per cubic meter.
PM2.5 was recorded at 7.4 micrograms per cubic metre in Islamabad, which is much lower than the National Environmental Quality Standards (NEQS) of 35 micrograms and the World Health Organisation (WHO) standard of 20 micrograms per cubic metre.
