PM2.5 refers to fine particulate matter with a diameter of less than 2.5 micrometers. The term is employed to characterize the levels of particles in both outdoor and indoor environments.
The air quality of Lahore has consistently remained unhealthy, not just over the past couple of months, but also in the last few years with the onset of the ‘fifth season’ of smog. The air quality levels continue to dip after September until at least February.
In view of the worsening air quality of the city and to combat the alarming levels of smog and air pollution, the administration has decided to shut down schools, markets, and government and private institutions every Wednesday for the next two months at least.
School administrations have been directed to ensure that staff members work from home on Wednesdays, allowing for a smoother transition to the new schedule. Banks, private institutions, clubs, and hotels are also expected to adhere to the Wednesday shutdown.
