Explanation

Linfen, China was ranked as the world's most polluted city in 2009 by the Blacksmith Institute due to severe coal mining and industrial emissions. While Mexico City was historically polluted, Linfen's air quality was worst in 2009. Chernobyl and Sumgayit were toxic sites but cities themselves weren't 'most polluted' in that ranking.
