About 90% of the global population in 2022 experienced unhealthy air quality and only six countries met the World Health Organization's recommendations for safe levels of air pollutants, according to a new report from Swiss air quality technology company IQAir .
IQAir measured air quality levels based on the concentration of lung-damaging airborne particles known as PM 2.5. Research shows that exposure to such particles can lead to heart attacks, asthma attacks and premature death. Studies have also linked long-term exposure to PM 2.5 with higher death rates from Covid-19.
When the WHO first published air quality guidelines in 2005, it said acceptable levels of air pollution were less than 10 micrograms per cubic meter. In 2021, the WHO changed its standard guidelines to below 5 micrograms per cubic meter.
The report found that the five most polluted countries in 2022 were Chad, Iraq, Pakistan, Bahrain and Bangladesh. The most polluted cities globally were Lahore, Pakistan; Hotan, China; Bhiwadi, India; Delhi, India; and Peshawar, Pakistan. Lahore's air quality worsened to 97.4 micrograms of PM 2.5 particles per cubic meter in 2022 from 86.5 a year earlier, making it the most polluted city in the world.
The report also said that India and Pakistan had the worst air quality in the Central and South Asian region, where more than half of the population lives in areas where PM 2.5 concentrations are around seven times higher than suggested levels. WHO.
Only six countries met the updated WHO limits: Australia, Estonia, Finland, Grenada, Iceland and New Zealand, the report said. The 2022 report used air quality data from more than 30,000 regulatory air quality monitoring stations and air quality sensors from 7,323 cities in 131 countries, regions and territories.
According to the Energy Policy Institute at the University of Chicago, air pollution takes more than two years off the average global lifespan. 60% of particulate air pollution comes from burning fossil fuels.
Air quality index (AQI) and PM2.5 air pollution in Albania
The average concentration of PM2.5 for the year 2022 in Albania is 2.9 times more than the value of the WHO's annual air quality guideline, ranking our country in 73rd place out of 131 countries of the list published for 2022.
