Level of atmospheric pollutants below authorized limits

ISLAMABAD, Jun 1 (UrduPoint/Pakistan Point News – Jun 1, 2022): Air quality in the federal capital on Wednesday was reported to be healthy as a reduction in airborne particles was recorded in the atmosphere and the pollutant levels also remained below authorized limits due to less car traffic on the roads.

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 low as pollutants were below allowable limits of the National Environmental Quality Standards (NEQS).

Hazardous Air Pollutant Particulate Matter 2.5 microns (PM2.5), which was a deadly air contaminant, remained at 26.63 micrograms per cubic meter on average, which is below the NEQS of 35 micrograms per meter cube and denotes healthy 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.

However, a peak was seen during rush hour, mainly due to congestion from automobiles traveling on the roads after school vans, office buses and public cars caused congestion on major thoroughfares, said an EPA official at APP.

Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) were recorded below the allowed ratio as they were recorded at 4.42 and 18.43 micrograms per cubic meter in the past 24 hours in the atmosphere relative to 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.
