Micro-pollution ravaging China and South Asia: study

Last year, 117 of the 200 most polluted cities in the world were in China.

Nearly 90 percent of the 200 cities beset by the world's highest levels of deadly micro-pollution are in China and India, with most of the rest in Pakistan and Indonesia, researchers reported Tuesday.

Taking population into account, Bangladesh emerged as the country with the worst so-called PM2.5 pollution, followed by Pakistan, Mongolia, Afghanistan and India, according to the 2019 World Air Quality Report, jointly released by IQAir Group and Greenpeace.
