The air residents of Nairobi breathe is poisonous and can cause serious ailments including heart and lung diseases as well as cancer, a study has revealed.

The amount of cancer-causing elements (carcinogenic material) in the air within the city is as high as 105 microgrammes per cubic metre, the study released on Thursday says.

This means the quality of air Nairobians breathe is 10 times more dangerous if the World Health Organisation’s (WHO) threshold of 20 micrograms per cubic metre for key air pollutants is anything to go by.

Exposure contributes the most to the risk of developing cardiovascular and respiratory diseases, says the study the University of Nairobi’s Institute of Nuclear Science and Technology conducted in partnership with Gothenburg University in Sweden and Columbia University’s Earth Institute.

I see a business opportunity.

Not really but you are thinking in the right direction.

As a small boy in the village, I used to love the fumes and dust by moving lorries. in fact, we used to chase the vehicles just to inhale that. many years later, i still get the same sensation a times when a Lorry passes me and covers me with dust and smoke fumes.
