Lahore has ranked as the world’s most polluted city, with residents advised to wear masks.
Nine days from unhealthy to the world’s most polluted city
This newspaper reported on 15 October that Lahore’s air quality index reached 210 — rated “very unhealthy” — with one monitoring point in the cantonment at 298.
The city has gone from very unhealthy to first in the world in nine days. The smog season has arrived on schedule.
The advice, again
Masks. Limited outdoor movement. Closed windows. Air purifiers for those who can afford them.
As this paper noted last week, every measure on that list is something an individual must buy or do. None addresses crop residue burning, transport emissions, industry or brick kilns.
No emergency source-control measures have been announced alongside this advisory either.
What “most polluted in the world” means in practice
Lahore has roughly 13 million residents. A seasonal ranking at the top of a global pollution table is not an abstraction for them — it is measured in hospital admissions for respiratory illness, in school closures, and in life expectancy.
The ranking recurs every autumn. The response recurs with it.
Punjab’s government banned province-wide gatherings for weeks this month on security grounds. It has not restricted the activities that produce the smog.
The number
Separate reporting puts the index at 344, rated hazardous — well above the 300 threshold at which health authorities advise everyone, not only vulnerable groups, to avoid outdoor exertion.
Nine days ago it was 210. It is now 344.
What source control would require
Crop residue burning, transport emissions, brick kilns and industrial stacks are the four contributors identified in every provincial smog plan of the last decade.
None is addressed by a mask advisory. Lahore reaching the ranking of world’s most polluted city is the outcome of decisions taken months earlier, in each of those four sectors.
