Beijing has upgraded its alert for air pollution from orange to red, the most serious level, on Monday afternoon.
The Beijing Emergency Management office has issued an orange alert in advance warning of heavy air pollution from December 7 to 9. Authorities said they will have improved supervision on factories and exhausts from cars, which are responsible for discharging pollutants.
North China’s Hebei Province has been covered in smog since Saturday evening. The Air Quality Index (AQI) of Baoding city, about 150 kilometers (about 93 miles) southwest of the capital Beijing, reached 477 on Sunday morning. The number indicates that there is heavy pollution, according to Hebei Meteorological Administration. The World Health Organization has set its safe limit as 25.
According to the city’s emergency management headquarters, during a red alert, kindergartens, primary and high schools are advised to suspend classes, outdoor operations of construction sites are banned and some industrial plants are required to limit or stop production.
Car use will be limited as cars are allowed on the roads on alternating days depending on the odd or even numbers of their license plates. In addition, 30 percent of government cars will be banned from streets on an odd/even basis.
According to the Beijing Municipal Environmental Monitoring Center, heavy air pollution will linger until Thursday. It is expected to disperse Thursday afternoon as a cold front arrives.
This is the first time Beijing has issued a red alert for smog since 2013 when Beijing adopted an emergency response program for air pollution.
Four-tier alerts–blue, yellow, orange and red–will be issued on “heavy pollution” days. Red alert, the highest, will be issued for heavy pollution that is expected to last more than three days.
