Capital’s air quality moderate as gusty weather slightly increases pollutant levels – Latest News – The Nation

ISLAMABAD — Air quality in the capital after scattered rainy thunderstorms turned subdued on Friday after pollutant levels, although below allowable limits, saw a slight spike in their atmospheric concentration.
Air quality was recorded as moderate as airborne particulates were noted below allowable limits in the atmosphere as well as pollutant levels due to constant rainy and gusty weather.
The air quality data was collected by the Pakistan Environmental Protection Agency (Pak-EPA) which monitors the level of air pollutants for 24 hours based on three data collection intervals of eight hours at different locations.
Pak-EPA data revealed that air quality throughout all three data monitoring intervals remained high as pollutants were below allowable limits of the National Environmental Quality Standards (NEQS).
Hazardous particulate matter air pollutant 2.5 microns (PM2.5), which was a deadly air contaminant, remained at 21.33 micrograms per cubic meter on average, which is above the NEQS of 35 micrograms per cubic meter and denotes unhealthy air quality.
PM2.5 is generated by engine combustion, industrial emissions, burning garbage or flammable materials, and dust blown by fast-moving cars traveling on uncemented stretches of road.
Additionally, frequent wildfires in the federal capital have also created high airborne particles, dust and particles in the atmosphere, an EPA official said.
Particulate matter had exceeded allowable limits beyond 40 microns before the onset of precipitation, mainly due to persistent hot and dry weather.
Nitrogen dioxide and sulfur dioxide were recorded below the allowed ratio as they were recorded at 3.64 and 12.52 micrograms per cubic meter in the last 24 hours in the atmosphere against the NEQS of 80 and 120 micrograms per cubic meter respectively. These effluents were mainly produced during operational activities of industrial facilities and factories that were already under control, he said.
He urged the masses suffering from respiratory problems and other critical heart or lung conditions to avoid prolonged visits outdoors and to wear face coverings and goggles when the air quality was unhealthy when walking outside. ventured outside.
