Floating dust coming from North China's Inner Mongolia Autonomous Region continued to haunt the national capital Beijing on Sunday, bringing hazardous air pollution to local residents.

Meteorologists warned local people to stay at home and shut up windows to prevent indoor air pollution.

The content of particulate matter in the air reached 500 microgramme per cubic meter in every hour, according to local environment monitoring stations.

Beijing's environmental protection authorities have intensified their efforts to clear up local streets with water to reduce the influence and harm of floating dust on the life and health of local residents.

It will become clear Sunday night and Monday, with daytime temperature rising to 23 degrees Celsius, according to local meteorological station.
