Under the red alert which was started on Tuesday, kindergartens, primary and high schools were ordered to be closed down, car use was restricted with odd and even number plates system and outdoor operations of construction sites were halted.

The Ministry of Environmental Protection said on Wednesday that the emergency measures cut pollutant emissions by 30 percent from 7 am to 5 pm on Tuesday.

The main gauge to measure pollution by the US Embassy Monitor in Beijing dropped to around 100 on Thursday after touching nearly 400 in the last two days. An over night cold wind was reported to have blown the polluted smog out of the city's skies.

Beijing had imposed the red-alert — the highest on a four-color scale, following a forecast of high pollution for three consecutive days. The density of PM 2.5 sulfates, commonly caused by coal-burning, was much higher on Tuesday while the air held far less PM 2.5 nitrates, mostly emitted by vehicles, Chai Fahe, deputy head of the Chinese Research Academy of Environmental Sciences said.
