Did you know that according to the WHO, 99% of the global population breathes air exceeding safe pollution limits? This alarming reality has dire consequences. Using comprehensive 2024 AQI rankings, we've compiled the definitive list of the Top 30 Countries and Regions Suffering from the Worst Air Quality this year. 

The worst countries even exceed the safety value of 5µg/m3 provided by the World Health Organization by 18 times. A large number of studies have shown that air pollution affects people's chances of respiratory diseases, heart disease, lung cancer and other diseases.

Discover where hazardous pollution levels pose the most severe threats to public health, which surprising locations made the list, and the critical factors driving this global air pollution emergency. Understanding these rankings is the first step toward demanding change and protecting your lungs.

Analyze

The worst air quality areas are mostly concentrated in Africa and Southwest Asia. They have one thing in common, which is that there are severe wind and dust, which causes a surge in particulate matter around them.

At the same time, the impact of population on the environment cannot be ignored. The larger the population base, the more likely the environment will deteriorate, such as in India and China.
