Nations With Worst Air Pollution Ranked By World Health Organisation

"There are some countries in the world where the air is so polluted you can forget about coming home with a healthy holiday glow.

The World Health Organization (WHO) released its 2014 report into global air pollution with some concerning finds.

The database looked at the air pollution levels of 1600 cities across 19 countries by using a reading called PM2.5 and PM10. PM2.5 is considered the best indicator of assessing health impacts from air pollution and examines the concentration of fine particulate pollution of 2.5 micrometers or less in diameter."

Nations with the worst pollution, according to WHO, are Pakistan, Qatar, Afghanistan, Bangladesh, Iran, Egypt, Mongolia, United Arab Emirates, India, and Bahrain.
