Top 10 Most Polluted Cities in the World - Page 5 of 9

Delhi, India

Do you ever imagine that Delhi will be on this list? From me, not. But most of the people not even surprised by the inclusion of this city because it was formerly the most polluted city in the world. The government of the country trying its best to clean the Capital city but there is a lot of work to do. They have got little bit of success in this but still, the average PM2.5 level of the city is 143. So, you can say that it is one of the most polluted cities in the world.
