According to data released by the World Health Organization (WHO), four of the worst polluted cities in the world are in Nigeria.

The four Nigerian cities listed are:

Onitsha, a city few outside Nigeria will have heard of -- has the undignified honor of being labeled the world's most polluted city by air quality. A booming port city in southern Nigeria, Onitsha recorded 30 times more than the WHO's recommended levels of particulate matter concentration.
 
The other three cities named and shamed in the WHO report are the transport hub of Kaduna, in the north, which came fifth, followed by the cities of Aba -- in sixth place -- and Umuahia, in 16th position, which are both trade centers in southern Nigeria.

Why is Nigeria so polluted?

The contributing factors to pollution are a reliance on using solid fuels for cooking, burning waste and traffic pollution from very old cars," Dr Maria Neira, WHO Director, Department of Public Health, Environmental and Social Determinants of Health, tells CNN.
 
At home, due to unreliable electricity supplies, many Nigerians rely on generators, which spew out noxious fumes often in unventilated areas.
On the street, car emissions go unregulated.

Steps towards a solution

"We need to do an assessment of the sources of pollution at city level, also work on better planning of urban collective transport systems, and take very old cars out of service," says Neira.
"Regarding the four cities in Nigeria, we would actually like to praise them. They are at least monitoring the pollution levels, others are not even monitoring the air, we know that some are very polluted.
 
"These four cities are moving towards taking action to reduce pollution."
