Pakistan and India dominate in World most Polluted cities list



NEW YORK – Indian capital New Delhi is the most polluted city in the world, says a study released by World Health Organisation (WHO).

The 2014 report of the Ambient Air Pollution (AAP) database contains results of outdoor air pollution monitoring from almost 1600 cities in 91 countries.

Thirteen of the dirtiest 20 cities were Indian, with New Delhi, Patna, Gwalior and Raipur in the top four spots. The Indian capital had an annual average of 153 micrograms of small particulates, known as PM2.5, per cubic metre.

The Pakistani city with the highest pollution levels was Karachi, which had a PM2.5 of 117 ug/m3. It came in at number five in the list of cities with the worst levels of air pollution. Peshwar (111 ug/m3) and Rawalpindi (107 ug/m3) came in at 6th and 7th respectively.

Iran’s city with highest level of air pollution was Khoramabad with a PM2.5 average of 102 ug/m3. It was ranked 8th in a list of city’s with high air pollution.

Coming in at number 9 is Indian city Ahmedabad (100 ug/m3) and 10th is Lucknow (96 ug/m3).

Air pollution killed about 7 million people globally in 2012, making it the world’s biggest environmental health risk, the W.H.O. reported last month. Some 80 percent of those deaths came from heart attacks and strokes, although air pollution also causes an increase in lung cancer deaths.
