Lahore tops world pollution ranking as AQI reaches 194

Lahore has become the most polluted city in the world as air pollution worsened with the Air Quality Index (AQI) reaching 194.

Air pollution was measured at 210 in Allama Iqbal Town, 207 on Barki Road, 187 in Model Town, 187 on Bedian Road and 186 in Defence.

This week, Lahore’s pollution levels have climbed, worldwide air quality monitors have reported. Lahore’s AQI was measured at about 19 times higher than the limits of World Health Organization.

Health experts have asked residents to keep their doors and windows shut during high pollution times and encouraged motorcyclists and outdoor workers to use masks.

Smog means smoke mixed with fog and numerous air pollutants including nitrogen oxides, sulphur oxides, ozone and other dangerous particles and gases. It can get worse when pollutants mix with sunlight and stagnant air, particularly if there isn’t much wind.

Heavy traffic, industrial emissions and pollutants collecting near the ground can cause smog.

Health experts warn that breathing filthy air over long periods can irritate the eyes, induce coughing and throat and chest irritation, and exacerbate respiratory disorders. Heavy air pollution can also raise the chance of significant lung and cardiovascular issues.

Children, the elderly and persons with pre-existing respiratory conditions are particularly sensitive and excessive levels of smog can cause or exacerbate asthma symptoms.
