The Top 10 Most Polluted Cities in the World: It is a Miracle that People Survive here

This is a very famous quote, “Pollution, If You Don’t Kill It, It will Kill You.” This is very true of the pollution levels in various countries of the world. Every human being has a right to breathe fresh air. However, that has become the most difficult thing to have access to in such times of pollution. Vehicles and industries are the main cause of pollution in the major cities.

Pollution can be of various types, air pollution, water pollution, etc. Each type of pollution is bad for the health of the people residing in these cities. The most visible kind of pollution is the air pollution. This type of pollution can directly affect the lungs of the people. There are many ways of determining the air pollution levels. Every country has its own criteria as far as determining the air quality is concerned. They measure the air quality index based on the levels of Particulate matter (PM2.5, PM10, etc.), Sulfur dioxide (SO2), Nitrogen Dioxide (NO2), Ozone (O3), Carbon Monoxide (CO), etc.

We present a compilation of the ten most polluted cities in the world. You can find the most of the cities are in the Asian subcontinent. This list can change very frequently because Delhi was among the most polluted cities in the world in the first half of 2016 but now it has slipped to the eleventh position.

We have taken the PM2.5 level as the main criteria for determining the pollution levels of these cities. Each of these cities has a PM2.5 level of more than 125. The satisfactory range is around 31 to 60. A PM 2.5 level more than 250 is very severe. It can cause serious health problems to its residents because of the minute size of the particles practically invisible to the human eye.

There are other indices as well such as Sulfur dioxide, Nitrogen Dioxide, etc. However, one can only state that any kind of pollution is bad. This explains why the major countries in the world have decided to move the industries away from the cities.
