India, at global level, is talked about for its poor air quality, especially, in its metropolitan cities. Burgeoning population, overuse of limited resources, increasing number of vehicles and industries are leading to a rise in particulate matter pollution and deteriorating air quality. The World Health Organization had conducted a study and collected average PM2.5 level for 1600 cities across the world in 2014 including 124 cities from India. The study found out that Delhi, which is the fifth-most populated metropolis in the world, had the worst air quality. Twelve other Indian cities among top 20 were: Patna, Gwalior, Raipur, Ahmedabad, Lucknow, Firozabad, Kanpur, Amritsar, Ludhiana, Allahabad, Agra and Khanna.
In most of the studies it has been revealed that air pollution leads to respiratory problems. The Central Pollution Control Board in 2008, conducted a comprehensive study in this regard and found out that Delhiites had 1.7 times higher prevalence of respiratory symptoms as compared to people living in rural areas where pollution is not high.
