A recent World Health Organization study that measured pollution in 1,600 cities found that Indian cities are some of the most polluted in the world, Reuters reported.

The study follows up on findings made in a smaller 2011 survey, and indicates that air pollution has worsened since then, particularly in poorer nations. The Indian cities of New Delhi, Patna, Gwalior and Raipur top the list as the most polluted cities on Earth, with 13 of the country’s other cities making the top 20.

The city of Beijing, China, ranked 77th, though its pollution data was from 2010. Based on hourly pollution data published by the Beijing city government since January 2012, the city would place 17th on the list.

Air pollution was responsible for the deaths of 7 million people in 2012, the WHO stated.
