Although the skies were blue over Beijing for nine of the past
29 days, April was a dusty month for the city with the most serious
air pollution in the past four years, said the municipal
environmental protection bureau Saturday.
Sandstorms from Mongolia and North China's Inner Mongolia Autonomous Region brought
floating dust into the city on seven occasions in April, said Pei
Chenghu, deputy director of the bureau.
As of Saturday the urban areas of Beijing had seen 60 days of
blue skies this year which is 16 less than the same period
The official said that on 17 days over the past four months
the city had been exposed to level four or five air
Pei said all the relevant departments in Beijing launched
pollution prevention and control activities to improve the
capital's air quality.
Beijing Construction Committee examined more than 9,000 building
sites and ordered nearly 3,000 of them to take measures to control
dust created by their work.
At the same time the municipal government will use 13,700 tons
of water to dampen down the floating dust in the streets.
Viewing the air quality records of the past few years no
floating dust has occurred in May and the official said he hoped
Beijing would have at least 20 days of blue sky during the month.
