Most Polluted Cities in the World (WHO, 2016)

Delhi is not the most polluted city in the world any more, according to the World Health Organisation's (WHO) urban air quality database released on Thursday. In fact, it now ranks 11th among 3,000 cities in 103 countries in terms of PM 2.5 (fine, particulate pollution) and 25th in terms of PM10 (coarse pollution particles) levels. This is though a considerable improvement since 2014 when Delhi was ranked the most polluted city in terms of PM 2.5 levels, WHO had monitored only 1600 cities last time. This time 1400 more cities have been included in the database.
