During the past week, Beijing has been covered with thick smog that is forecast to stay until this weekend at least.

The smog, covering 1.43 million square kilometers mainly in northern China, made the Beijing government give an orange alert - the second-highest warning - and ordered people not to leave their homes.

A study in 2013 by researchers at Tsinghua University said that there were more than 1,300 microbes(可吸入颗粒) in the atmosphere over Beijing. Although most of them may do no harm to human health, the number still makes people worried.

Zhuang Guoshun, director of the Center for Atmospheric Chemistry Study at Fudan University, said Beijing is covered by smog for an average of 60 percent of the year, while the number for Shanghai is 30 to 50 percent.
