Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
The January 2024 version of the WHO database contains results of ambient (outdoor) air pollution monitoring from almost 5,390 towns and cities in 63 countries. Air quality in the database is represented by the annual mean concentration of particulate matter (PM10 and PM2.5, i.e. particles smaller than 10 or 2.5 micrometers, respectively). [1 ...
[1] [2] By default the least polluted cities which have fewest particulates in the air come first. Click on the arrows next to the table's headers to have the most polluted cities ranked first. Click on the arrows next to the table's headers to have the most polluted cities ranked first.
Here are key regional takeaways from IQAir’s 2023 World Air Quality Report. Asia is the world’s most polluted region. All but one of the 100 cities with the most polluted air in the world are ...
In the 2024 “State of the Air” report by the American Lung Association, despite decades of progress cleaning up air pollution, 39% of people living in America (131.2 million people) still live ...
This index pays particular attention to people who are sensitive to air pollution. It provides them with advice on how to protect their health during air quality levels associated with low, moderate, high and very high health risks. The AQHI provides a number from 1 to 10+ to indicate the level of health risk associated with local air quality ...
Air pollution costs the world economy $5 trillion per year as a result of productivity losses and degraded quality of life. [24] [25] [26] These productivity losses are caused by deaths due to diseases caused by air pollution. One out of ten deaths in 2013 was caused by diseases associated with air pollution and the problem is getting worse.
Air pollution forecasting is the application of science and technology to predict the composition of the air pollution in the atmosphere for a given location and time. An algorithm prediction of the pollutant concentrations can be translated into air quality index , same as actual measurements.
