It is interesting that when you google any of the countries from our list of 12 countries with the dirtiest air in the world, you will find results that state that this particular country has the dirtiest air in the world. The same thing goes for Qatar, although it is not at the top of our list. Air pollution in Qatar exceeds safe limits, and it is a cause of major health issues. According to Doha News, Qatar’s urban areas have an annual average of 105 μg/m3 of PM2.5 which is very high. These particles are made up of heavy metals and cannot be seen by the bare eye, but they impact respiratory system and can cause a cough, reduced lung function, chronic bronchitis, lung cancer and many other health issues.
