Smog that has shrouded the Chinese capital since Sunday might persist for a few days, the Beijing Environmental Protection Bureau said on Monday.

Because of the low-pressure system in the atmosphere, the smog, which came on Sunday and worsened on Monday, is likely to persist until Thursday, as weather patterns will not help disperse it, said Xiang Kaiyue of the bureau's publicity staff.

The downtown area saw a PM2.5 intensity of 258 micrograms per cubic meter around noon, while the particulate level in the southwestern part of the city soared to 288 micrograms per cubic meter, according to the Beijing Environmental Monitoring Center.

The air quality index stood at 294 by 2:30 pm, indicating serious air pollution.

The bureau suggests members of the public take measures to protect themselves, advising that children, seniors and those with heart and lung problems stay indoors and that students suspend or reduce outdoor physical exercise.

It also encouraged the public to use public transportation for trips and private vehicle drivers to shut off their engines whenever possible to reduce exhaust emissions.

The government issued a yellow smog warning on Monday afternoon to alert the public of the hazard.

It vows to conduct more inspections of construction sites, freight vehicles and outdoor coal burning to reduce emissions. No outdoor barbecues or fireworks are permitted in the city under the yellow warning.
