Finish the blue sky goal ahead of time in Beijing

Finish the blue sky goal ahead of time in Beijing Environmental Protection Agency acknowledges air quality is relatively low
These days, the person with gauze mask in Beijing street is getting more and more. And net friend talk in professional jargon, say wear gauze mask to be enough, self-provided oxygen face guards rest assured.

December 17, Beijing Municipal Environmental Protection Agency release information, say up to the same day, the intersection of Beijing and with better than in days of two class, up to 274 days totally second air quality, 72 days of one class among them, than many 11 days of the whole year of 2008 hosting Olympic Games, achieve the historical best level. Also, Beijing " blue sky " of this year The goal has already been finished ahead of time.

But the Environmental Protection Agency admits: Present air quality is only a lower level, there is certain disparity between expectation and requirement of public distance.

Except " blue sky " Also pay close attention to the pollution density

A lot of citizens are still unsatisfied with the days of two class of Beijing. As to this, Beijing relevant person in charge of Municipal Environmental Protection Agency says, hopes masses especially pay close attention to second day in the future, should pay close attention to pollution density more, because what the country examined is the density of the pollutant, the current method is monitored to the pollutant density too in the world, contrast.

This person in charge says, in the past three years, the inhalable particles wander up and down about 121 micrograms / cubic meter in the atmosphere of Beijing, break through to some extent this year, drop by 5% compared with the same period of last year, the sulfur dioxide drops by 12.9% compared with last year, it is about 27 micrograms / cubic meter. This year, because the motor vehicle is increasing constantly, the density of larger urban NO2 in the whole country is increasing, but Beijing is still 56 micrograms / cubic meter, and fair last year.

Eliminate 100,000 old motor vehicles from reducing PM2.5

This period of time, " PM2.5 (can enter the lung particulate matter) " Become the hot word, make a noise in popular anxiety.

As to this, Beijing Municipal Environmental Protection Agency emphasizes, one of the main sources of PM2.5 is particle two times that sulfur dioxide, NO2 are produced by the photosynthesis. So, the reduction of the sulfur dioxide, NO2, will reduce production of the particle two times in the atmosphere, reduce PM2.5. It is a long-term course to improve the air pollution. Beijing has already lasted ten years to improve, but the pollutant is great in emission, air quality improves the difficulty bigger. The developed country manages PM2.5, has spent the course of the 30 or 40 years too.

Beijing proposed, would eliminate the old motor vehicle of more than 100,000 in 2012. The relevant person in charge of Municipal Environmental Protection Agency says, if make great efforts to manage motor vehicle and pollution from coal burning, to subdue sulfur dioxide and nitrogen oxide, just few that particle two times in the atmosphere is produced, this can reduce PM2.5.
