Pollution has been a serious problem in Delhi for the last few years.
New Delhi: According to a new report published on Tuesday, 13 of the top 20 most polluted cities in the world are in India. In this list of polluted cities, Bernihat of Assam tops the top. The World Air Quality Report of Swiss Air Quality Technology Company IQ, 2024, states that Delhi remains the most polluted capital globally, while India has become the fifth most polluted country in the world in 2024. Let us know that India was third in 2023 in this list.
Pollution remains continuously in Delhi
The report stated that India saw a decline of 7 percent in PM2.5 concentrations in 2024, which in 2023 has reduced to an average of 50.6 micrograms per cubic meter as compared to 54.4 micrograms per cubic meter. Nevertheless, 6 out of the 10 most polluted cities in the world are in India. Delhi was consistently recorded high pollution levels, with the annual average PM2.5 concentrations of 91.6 micrograms per cubic meter, which was around 92.7 micrograms per cubic meter in 2023.
These are the most polluted countries in the world.
Average age decreases by 5.2 years
The top 20 most polluted cities in the world are 13 Indian cities: Bernihat, Delhi, Mullanpur (Punjab), Faridabad, Loni, New Delhi, Gurugram, Ganganagar, Greater Noida, Bhiwadi, Muzaffarnagar, Hanumangarh and Noida. Overall, 35 percent of the annual PM2.5 level in Indian cities is 10 times more than 5 micrograms per cubic meter. Air pollution in India has reached a dangerous condition and due to this, the age of a common Indian is reduced by an average of about 5.2 years.
Many diseases are caused by pollution
According to a study by Lancet Planetary Health published last year, about 1.5 million deaths in India from 2009 to 2019 were potentially related to long -term contact of PM2.5 pollution. PM2.5 means smaller air pollution particles than 2.5 microns, which can enter the lungs and bloodstream, which can cause problems in breathing, heart disease and even cancer. Sources include vehicle smoke, industrial emission and burning of wood or crop waste.

‘Now we need action’
Former WHO Chief Scientist and Advisor to the Ministry of Health Soumya Swaminathan said that India has progressed in air quality data collection, but has not taken adequate action. He said, ‘We have data; Now we need action. Some solutions are easy to replace biomass with LPG. India already has a plan for this, but we should give more subsidy on additional cylinders. The first cylinder is free, but the poorest families, especially women, should get more subsidies. This will improve their health and reduce external air pollution.
‘Mixing of encouragement and punishment is necessary’
Vishwanathan said, ‘It may be helpful to expand public transport in cities and impose penalty on some cars. A mixture of encouragement and punishment is necessary. Former Director General of Indian Council of Medical Research said, “Finally, strict adherence to emission laws is very important. Industries and construction sites should follow rules and install equipment to cut emissions instead of adopting shortcuts. (Language)
