HANOI (Reuters): The streets of Vietnam's capital city Hanoi were enveloped in thick smog on Monday which dramatically reduced visibility due to air pollution caused by high levels of particulates from vehicle emissions and construction-linked fine dust.
Levels of hazardous small particles known as PM2.5 in the air in Hanoi were at 187 micrograms per cubic metre late on Monday, the highest among a list of most polluted international cities, according to data from AirVisual, which provides independent global air pollution information via a phone app.
