Air quality improves as pollution declines in Balochistan amid lockdown.

QUETTA -- Like the rest of the country's environment, Balochistan being the largest province by area also observed drastic improvement in air quality and overall ambience in its various districts.

Balochistan, which covers 44 percent of the country's total area and occupied around 760 km of coastline has witnessed clean atmosphere due to the lockdown amid COVID-19 pandemic, said an official of the EPA, Muhammad Khan while talking to reporter on Friday.

According to the data, Air quality parameters indicate a significant reduction in the pollution level in the atmosphere such as nitrogen dioxide (NO2), sulphur dioxide (SO2), ozone (O3), carbon monoxide (CO), particulate matter (PM2.5 and PM10).

Prior to the lockdown, NO2 was between 3.2-50 ug/mA3 and in April 2020 that value has been reduced to 1.0 ug / mA3, which was a good thing. The value of O3 is 93.4 ug / mA3, which is moderate compared to before the lockdown. Similarly, SO 2 has seen a decline from (5-120 ug / mA3) to 1.0 ug / mA3 which was a...
