The majority will think that Beijing or some cities in China will top the world as the place with most polluted air. But according to World Health Organisation data covering more than 1000 cities in 91 countries, China's capital is not the city that consistently endures the world's worst air pollution. It doesn't even come close.
One of the crucial measures of dangerous air pollution is the number of parts per million of particles smaller than 10 micrometres (PM10) wafting through the air. Beijing's residents breathe in air with an average PM10 of 121, but millions of people have it worse.
"Beijing PM10 Level .... 121"
"Ahwaz, Iran ..... 372
Ulaanbaatar, Mongolia .... 279
Delhi, India ... 198"
Farther down the list are more cities in Iran, along with some in India, Pakistan, and Botswana, before Delhi appears in the 12th spot, with average particulate levels of 198 parts per million.

From the data supplied by W.H.O. I managed to glance through some cities in Malaysia and their recorded PM10 ... we should be thankful but must still be vigilant over issues such as location of certain manufacturing businesses, issues over open burning and excessive deforestation issues.
