Hanoi has become the world’s seventh most polluted capital city, even worse than Beijing, a new IQ AirVisual report says.
The city’s worsening air quality saw its average PM2.5 level last year rise to 46.9 micrograms per cubic meter of air from 40.8 in 2018, according to a report released this week by Switzerland-based air quality monitor, IQAir AirVisual.
The 2019 World Air Quality Report says that for the first time, Hanoi has overtaken China’s Beijing, the world’s most suffocating capital just a few years ago. The Chinese capital city has improved to ninth on the list with its average PM2.5 level at 42.1.
