Hazardous Smog in China to Last for a Week: Officials
Beijing authorities on Thursday issued a derisory “Yellow Alert” for the Chinese Capital as heavy air pollution enveloped the region. The smog, previously described as “Apocalyptic” by the residents, is forecast to last for a week.
“Beijing, its neighbors Tianjin and Hebei Province, as well as central and western Shandong Province can expect heavy air pollution to linger for a week, according to a joint weather forecast issued by the China Meteorological Administration [CMA] and the Ministry of Environmental Protection,” said a report.
CMA believes the smog will last for a week because there is no cold front in sight to help disperse it, said the report.
PM 2.5 AQI had risen to 374 and PM10 concentration was hovering above 160µgm–³, as of posting.
Pollution levels below 15.4µgm–³ (AQI of up to 50) are considered as “safe.”

“Yellow” is the 2nd lowest of a four-tier alert system—red, orange, yellow, blue—indicating the severity of air pollution.

“A red alert indicates the most serious air pollution (AQI above 300) for three consecutive days. An orange alert indicates heavy to serious air pollution (AQI between 200 and 300) alternately for three consecutive days. A yellow alert means severe pollution for one day or heavy pollution for three consecutive days,” said Xinhua.
