New Delhi the most polluted city of the world

The Indian capital New Delhi has been named the most polluted capital in the world for the third consecutive year.

Reuters reported that the “Global Air Quality Report 2020” released by the Swiss agency IQAir, which tracks air quality, shows that the average annual concentration of PM2.5 per cubic meter of air in New Delhi in 2020 is 84.1.

The report said that of the 50 most polluted cities in the world, India accounted for 35. The report collected data from 106 countries.

In addition, New Delhi’s PM2.5 air sewage standard is nearly 6 times higher than the World Health Organization’s annual average of 10 micrograms per cubic meter (10μg/m3).

IQAir is based on the annual average concentration of PM2.5, which is harmful to the lungs, as the basis for air quality measurement. Long-term exposure to PM2.5 may cause fatal diseases, including cancer and heart problems.

According to the report, India’s national COVID-19 restriction measures implemented in 2020 have reduced the country’s annual average PM2.5 level by 11%; however, India is still ranked as the third most polluted country in the world, second only to Bangladesh and Pakistan.
