Beijing Issues Orange Warning for Level-5 Heavy Pollution for Next Three Days

(Yicai Global) Dec. 2 – Beijing is set to be hit by heavy air pollution due to adverse weather conditions. Authorities in Beijing have issued an orange warning against expected heavy pollution over the next three days in the capital city. Beijing will have level 5 heavy air pollution between Dec. 2 and 4, warned Beijing Advance Warning and Information Release Center.

Kindergartens, primary and middle schools can halt outdoor activities, recommended the Center for Emergencies and Beijing Heavy Air Pollution Emergency Response, also inviting the public to take preventive measures. Vehicles transporting construction wastes, muck and concrete will also be barred from the roads.

According to China's existing "national standards" for air quality, a heavy air pollution event occurs if PM 2.5 concentration is greater than 150 micrograms per cubic meter, equal to an over 200 air quality index (AQI). This would prompt one of the four levels of air pollution warnings, namely blue, yellow, orange and red, the most serious. An orange warning means heavy pollution is forecast to last for three consecutive days, 72 hours.
