As per the World Health Organization (WHO), there are 14 Indian cities included in the top 20 most polluted cities in the world. These cities have been ranked as per the data on PM2.5 in the air.
Well, the particulate matter that is PM 2.5 contains pollutants that has the greatest risk to our health.
Most polluted cities in the world list include New Delhi, Gwalior, Kanpur and other. Varanasi is the most polluted city.
Major sources of air pollution from particulate matter – pollutants like sulphate, nitrate and black carbon – include inefficient use of energy by households, industry, agriculture and transport sectors, and coal-fired power plants.
As per study, around seven million people die every year from exposure to fine particles in polluted air.
Most Polluted Cities in World:
- Kanpur- Mean PM2.5 : 173 ug/m3
- Faridabad- Mean PM2.5: 172 ug/m3
- Varanasi– Mean PM2.5: 151 ug/m3
- Gaya- Mean PM2.5: 149 ug/m3
- Patna- Mean PM2.5: 144 ug/m3
- Delhi- Mean PM2.5: 143 ug/m3
- Lucknow– Mean PM2.5: 138 ug/m3
- Bamenda, Cameroon- Mean PM2.5 : 132 ug/m3

- Muzaffarpur- Mean PM2.5: 120 ug/m3

However, WHO report also stated the efforts made to reduce the pollution and improve people’s health. It also referred India’s Pradhan mantra Ujjwala Yojana. Under this scheme, in just 2 years government has provided37 million women free LPG connection. India aims to reach 80 million households by 2020.
A 2015 survey quoted about 1.1 million people die in a year from the impact of air pollution in India.
The report provides air quality data from more than 4,300 cities and towns in 108 countries, constituting the world’s biggest database of ambient, or outdoor, air pollution.
The UN agency’s assessment is based on satellite data and modelling overlaid on the database of cities, which is self-selecting because it is based on voluntary reporting, with numbers that have been hugely revised since the previous report.
