Delhi has earned the dubious distinction of becoming the most polluted major city in the world with an air quality index (AQI) of 527 on Friday, as per data by Air Visual on the World AQI rankings. The data is updated frequently, so the caveat is that rankings and AQI counts change accordingly during the day itself.
Delhi air quality broke all records on November 5, when it was in the hazardous range for nine consecutive days, making this the longest spell of hazardous air quality since public records began, according to Air Visual.
Delhi's air pollution has been making international headlines and while India endeavours to become a global superpower, the state of air pollution in the national capital is ticking all the wrong boxes for global tourists, investors and the international perception.
As per the world AQI rankings, Delhi is followed by Lahore at 234. However, there is a huge gap between the two and Delhi is suffering more pollution with a difference of more than two times.
At third spot is Tashkent, Uzbekistan, at 185 count which is a surprise because it is in a region considered to be not so congested.
Karachi is at the fourth place with an AQI count of 180, followed by Kolkata at 161 in the fifth place. China marks its entry with Chengdu with an AQI of 158.
Hanoi, Vietnam, with an AQI of 158 is at the seventh spot followed by Guangzhou in China with an AQI of 157. Mumbai is in the ninth place with an AQI of 153 and the dubious Top 10 concludes with Kathmandu at 152.
