Congratulations New Delhi, you have the world's most polluted air. A new survey from the World Health Organization asked cities to measure their pollution levels and found that 13 of the top 20 most polluted locations were in India. The study results, which encompassed 1,600 cities, discovered global air pollution had worsened since a similar survey was administered three years ago.

The Indian capital had an average of 153 micrograms of the dirty air particulate PM2.5 per cubic meter. Notably, notoriously smoggy Beijing had a PM2.5 reading of 56, which dropped it to 77th place. There are doubts, however, about whether the city properly recorded the data. The WHO claims the most recent data made available to them was from 2010 — despite the fact that the Chinese government has recorded hourly PM2.5 data since January 2012.
