- About 90% of the worldwide population will encounter unhealthy air excellent in 2022, according to a new report from Swiss air excellent technologies business IKAir.
- IKAir measured air excellent levels primarily based on the concentration of lung-damaging particles in the air identified as PM two.five.
- The report identified that the major 5 most polluted nations in 2022 are Chad, Iraq, Pakistan, Bahrain and Bangladesh.

About 90% of the worldwide population will encounter unhealthy air excellent in 2022, and only six nations have met the Globe Well being Organization’s suggestions for secure levels of air pollutants, according to a new report by Swiss air excellent technologies business IKAir.
IKAir measured air excellent levels primarily based on the concentration of lung-damaging particles in the air identified as PM two.five. Analysis shows that exposure to such particles can lead to heart attacks, asthma attacks and premature death. Research have also linked lengthy-term exposure to PM two.five with greater death prices from Covid-19.
When the WHO 1st published air excellent recommendations in 2005, it mentioned acceptable levels of air pollution have been much less than ten micrograms per cubic meter. In 2021, the WHO changed its reference recommendations to under five micrograms per cubic meter.
The report identified that the major 5 most polluted nations in 2022 are Chad, Iraq, Pakistan, Bahrain and Bangladesh. The most polluted cities globally have been Lahore, Pakistan Hotan, China Bhiwadi, India Delhi, India and Peshawar, Pakistan.
Lahore’s air excellent has deteriorated to 97.four micrograms of PM two.five particles per cubic meter in 2022 from 86.five in the prior year, generating it the most polluted city in the planet.
The report also mentioned that India and Pakistan suffered the worst air excellent in the Central and South Asian area, exactly where much more than half of the population lives in regions exactly where the concentration of PM two.five particles is about seven occasions greater than the level suggested by the WHO.
In the US, the most polluted huge cities have been Columbus, Ohio, followed by Atlanta, Chicago, Indianapolis and Dallas. Air excellent in Columbus reached 13.1 micrograms of PM two.five particles per cubic meter in 2020, generating it the most polluted key city in the US
This year, the Biden administration proposed limiting industrial particulate matter pollution from the present annual level of 12 micrograms per cubic meter to in between 9 and ten micrograms per cubic meter. Some public overall health advocates criticized the proposal as not going far adequate.
Only six nations met the updated WHO overall health limits: Australia, Estonia, Finland, Grenada, Iceland and New Zealand, the report mentioned. The 2022 report makes use of air excellent information from much more than 30,000 regulatory air excellent monitoring stations and air excellent sensors from 7,323 cities in 131 nations, regions and territories.
Air pollution requires much more than two years off the typical worldwide lifespan, according to the University of Chicago’s Power Policy Institute. Sixty % of particulate air pollution comes from burning fossil fuels.
“Also quite a few men and women about the planet never know they are breathing polluted air,” Aidan Farrow, senior air excellent scientist at Greenpeace International, mentioned in a statement.
“Air pollution monitors offer tough information that can inspire communities to demand alter and hold polluters accountable, but when monitoring is patchy or patchy, vulnerable communities can be left with no information to act on,” Farrow mentioned.
