The 5 Most Polluted Cities In The World


Although the levels CO2 emission, thus, the levels of pollution vary according to the city in which you reside, a vast number of people spread around the world are exposed every day to pollution. There are cities in which many children cannot go out to play and in which all residents must go out wearing masks to avoid breathing hazardous air particles.

The side effects of pollution are well-known, especially lately

We know, for example, that pollution negatively affects human health with respiratory diseases such as pneumonia. It is also known that it is one of the reasons for climate change and that acid rain directly affects water sources, forests, wildlife, and agriculture.

But, in addition, the clouds of polluted air reduce the visibility and the inhabitants of the most polluted cities in the world live under a thick mist that neither allows them to see the blue of the sky nor the brightness of the stars.

That is why, next, we will learn about the five most polluted cities in the world, according to the World Health Organization (WHO).

The 5 Most Polluted Cities In The World

Zabol, Iran

Although most of the polluted cities are so due to CO2 emissions, the inhabitants of Zabol have nothing to do with this.

This city, located in southeastern Iran, suffers, every summer, from persistent sandstorms that make the air become unbreathable. Due to this fact, Zabal is considered the most polluted city in the world, by natural causes.

Gwalior, India


The city of Gwalior, situated in the center of India, is the most polluted in the country, the first in the world by human-caused pollution, and the second in the world by the worst air quality.

The population density, the increase in the number of vehicles, and the industries that emit CO2 emissions among other toxins are some of the factors that make the air dangerous to breathe in Gwalior.

Allahabad, India

Allahabad is a city located in Northern India and is massively affected by sandstorms, vehicular gases emissions, pollution of industrial plants, and deforestation.

Riyadh, Saudi Arabia

The capital of Saudi Arabia, Riad, is affected by CO2 emissions produced by traffic and industrial pollution, as well as by sandstorms.

Al Jubail, Saudi Arabia

This city, located on the Saudi Arabian coast of the Persian Gulf, was designated in 1975 by the Government as the new industrial city and, since then, it became a complex of petrochemical plants.
