[Graphic News] Lahore is most polluted city, Chad worst among countries: survey
By Nam Kyung-donPublished : April 10, 2023 - 08:01
Lahore in Pakistan jumped more than 10 places to become the city with the worst air quality in the world in 2022, according to an annual global survey by a Swiss air purifier manufacturer.
The report published by IQAir also said that Chad in central Africa had replaced Bangladesh as the country with the most polluted air last year.
IQAir measures air quality levels based on the concentration of lung-damaging airborne particles known as PM2.5. Its annual survey is widely cited by researchers and government organizations.
Lahore’s air quality worsened to 97.4 micrograms of PM2.5 particles per cubic meter from 86.5 in 2021, making it the most polluted city in the world.
Hotan, the only Chinese city in the top 20, followed Lahore with PM2.5 levels of 94.3, an improvement from 101.5 in 2021. (Reuters)
