New Delhi : Gurugram in the National Capital Region (NCR) has been named as the world's most polluted city, said a study by IQAir AirVisual and Greenpeace. As per latest data released in the study, India dominates the list with 15 out of 20 cities from across the world.

Among the top 10, seven are from India; one is in China and the other two cities are from Pakistan.

Among the Indian cities are Gurugram, Ghaziabad, Faridabad, Bhiwadi, Noida, Patna and Lucknow. The other three are Hotan in China and Lahore and Faislabad in Pakistan.

While, there have been much of a hustle about pollution in Delhi, the national capital missed the top 10 list and has been placed at number 11.

Data for the report has been sourced from public and government websites collected in real-time and in cases where real-time was missing, "queries were performed to collect historical data when it becomes available."

The main focus of the study, as per the report, is the aggregate of Particulate Matter (PM) 2.5, which has been recorded in real-time in 2018.

China has made a remarkable improvement since 2013, when its capital Beijing topped the pollution charts but according to the new study, the country's pollution levels have gone down by 40 per cent.
