You will be surprise to know that the world's most polluted city isn't Beijing or Delhi.

According to a new report from the World Health Organization, the pollution in megacities like Beijing China, Delhi India and a host of others are actually only a tip of the iceberg and the cities with the worse case of pollution in the world is probably in Iran and Nigeria.


The World's Health Organization studied air qualities of the cities and the size of particles found in the air. Generally, a lot of attention is placed upon particles of a PM2.5 size, which is around one-30th the size of a human hair. These particles are particularly worrying because they have the ability to enter lungs and blood tissue and cause serious health problems.

However, you can also measure larger particles in the air. At PM10, the particles are coarser, though they can still be inhaled and cause health problems.

Based on PM2.5 Zabol in Iran comes out on top and based on PM10 Nigeria's Onitsha, a city of half-a-million people on the Niger River, is atop this list. The city has been known for its rapid growth and gridlock, though some locals were apparently still surprised that it appeared so high on the list. See more data below:

Gas pollution. It's as a result o sharp increase in population and poorly processed fuel.

You folks are unbelievable

Four Nigerian cities on that list. Not good at all.

Another big lie from dis people! This Onitsha wey I know kwa?

The SE is just very very dirty

I was believing this report until I say umuahia. You and your report are the greatest joke of the century. Umuahia may not be the flashy, skyscraper city but I bet it is more neater than 80% if not 90% of the cities in Nigeria.
You guys took a wrap of weed at the tail end of that statistics.

This is by World Health Organization. If you like believe, if you don't na you sabi. Y'all are just dirty people.

This is a report by WHO and you will note probably so not necessarily that they analysed every city, plus Onitsha is measured based on PM10 which states that the pollution in the air coarser, though they can still be inhaled and cause health problems. But that of Zahol Iran is kinda bad as its based on PM2.5 which more dangerous
