1Pakistan's second-largest city, Lahore, has been named the city with the most polluted air in the world in 2022.
2IQAir, a Swiss company that makes air purifiers, puts out a yearly world air quality report.
3The report is recognized by researchers and government agencies around the world.
4IQAir measures air pollution based on the presence of airborne particles that damage the lungs.
5The particles are called PM2.5.
6The measurements for IQAir's report come from 30,000 air quality monitors in 131 countries around the world.
7In 2022, Lahore had 97.4 micrograms of PM2.5 per cubic meter.
8That is up from 86.5 in 2021.
9The Chinese city of Hotan was second, with 94.3 micrograms.
10Two cities in India came next on the list: Bhiwadi, which is outside of Dehli, and Dehli itself.
11Those cities both measured at over 92 micrograms.
12The World Health Organization (WHO) has said cities should have a maximum measurement of just 5 micrograms of PM2.5 per cubic meter.
13That means the most polluted cities on IQAir's list have 18 to 20 times more than the acceptable level.
14IQAir also said the African nation of Chad was the world's most polluted country in 2022.
15The average measurement in Chad was 89.7.
16Iraq was second at 80.1. Pakistan was third and Bahrain was fourth.
17In 2021, the most-polluted nation was Bangladesh.
18It moved down to fifth in 2022.
19India and Pakistan had the worst air quality among countries in Central and South Asia.
20Sixty percent of people living in Central and South Asia live in areas with extremely poor air quality, the report said.
21The IQAir report also noted that 10 percent of the world's people live in a place where air quality threatens their health.
22The U.S. territory of Guam in the Pacific Ocean had cleaner air than any country, IQAir said.
23For a capital city, Canberra, Australia ranked as having the cleanest air.
