(Yicai Global) Dec. 20 – Air pollution has reached its worst level in North China this winter so far, with the air quality deteriorating further in Hebei Province—the nearest province to Beijing., PM 2.5 (particulate matter measuring less than 2.5 micrometers in diameter) and PM 10 have even exceeded 1,000 micrograms/cubic meter at a monitoring station in Hebei's provincial capital Shijiazhuang.
Heavy pollution worsened yesterday, and air quality indexes went "off the charts" in three cities in Hebei—Shijiazhuang, Xinji and Handan, state-owned Xinhua news agency reported. Shijiazhuang tops the list of worst polluted cities. According to the national urban air quality real-time monitoring platform, PM 2.5 and PM 10 detected by a monitoring station at the Century Park in Shijiazhuang reached 1,015 micrograms/cubic meter and 1,132 micrograms/cubic meter respectively at 1 p.m. yesterday.
As an important base of heavy industries such as steel and pharmaceutical production in China, Hebei is often plagued by air pollutant emissions. When coupled with stagnant atmospheric circulation, it gets worse, causing greater pollution problems.
The cold weather will partly clear up the pollution today, but it will set in tomorrow again to stay until Dec. 23, the weather forecast predicts.
