Beijing air pollution

The Chinese capital has for many years suffered from serious air pollution. Primary sources of pollutants include exhaust emission from Beijing's more than five million motor vehicles, coal burning in neighbouring regions, dust storms from the north and local construction dust. A particularly severe smog engulfed the city for weeks in early 2013, elevating public awareness to unprecedented levels and prompting the government to roll out emergency measures.

Heavy smog has cancelled at least 20 flights at Beijing’s Capital International Airport on Wednesday morning.

Nearly half of the cancelled flights were international arrivals and departures. These included flights to and from Singapore, Kuala Lumpur, Warsaw and Munich.

Eighteen domestic departures were also grounded, according to the BCIA website’s flight schedule, which was last updated at 9.45am.

The airport released a statement on its Chinese-language website saying severe haze would affect flight traffic until 10am.

It advised passengers to check the local weather report and to contact their airlines for the latest flight arrangements.

The US embassy’s air pollution index reading for PM2.5 – or respiratory particulates smaller than 2.5 micrometres in diameter – stood at 434 per cubic metre that morning, a level considered to be hazardous.

The Beijing Meteorological Bureau issued a yellow alert for heavy fog on Tuesday, indicating visiblity had fallen to less than 100 metres.

Similar air and weather conditions have affected air traffic across northern China in the previous three weeks.

On Sunday, Beijing issued an orange fog warning after visibility had fallen to less than 200 metres. Ten flights were cancelled the following day. Flights were also affected in Hebei, Hunan, Yunnan, Guizhou, Zhejiang, Jiangsu, Jilin, Heilongjiang and Sichuan provinces, with visibility reduced to about 100 metres at some airports.

Heavy snow over the weekend forced the cancellation of 111 flights at BCIA, 16 of which were international. Nearly 70 flights were delayed on Sunday morning.
