by Mr. Du Shaozhong means, in the “weather is not conducive to pollutant dispersion conditions” appear under the fog, “is relatively easy to form air pollution.” “Mandarin” is: no wind, fog, easy to form air pollution. Click here, if the opposite occurs, the wind, no fog, not easy to form air pollution. Formed in the pollution of air pollution sources, Beijing main source of pollution is vehicle exhaust, no wind, fog, or wind, no fog, car exhaust emissions should be, with the vehicle exhaust air pollution related to follow suit has nothing to do with the fog.
Mr. Du Shaozhong said, “these two methods are not comparable, the U.S. Embassy is a point, can not evaluate an area … they were not the same as our approach, we are the city twenty-seven point automatic monitoring system, evaluation of a city air quality, need a system can not be judged by a point. “
not to PM2.5 air quality standard, and why? Like the development of poverty indicators, ten yuan a day for the index and the index of $ a day, the results are different: poverty indicators set too high, the poor, the more; set too low, the poor less. Of course, we “like” the poor less. Similarly, we of course “like” the air is good. Air targets set too low, easy compliance. Our target is not the actual air hazard set, but according to the wishes of the elite set. Mr. Du Shaozhong he said: “As long as the monitoring of pollutants increase the passing rate will be reduced … ….” Seen the development of monitoring indicators to be considered qualified.
on the U.S. Embassy in air quality monitoring data
Mr. Du Shaozhong said, “fall and winter seasons, prone to static wind, temperature inversion.” The message in the Xinhua News Agency, this sentence is: in the case of heavy fog, “is easy to form a calm wind, static stability and other adverse weather conditions.” “Modern Chinese Dictionary” in finding out the “calm wind, temperature inversion, static stability,” perhaps this is a meteorological term three words. Fortunately, you can literally try to speculate, “calm wind, steady state” is “no wind.” As for the “inversion” high-tech, ordinary people do not understand. Here we must ask Mr. Du Shaozhong: “temperature inversion” mean?
Mr. Du Shaozhong said PM100 (one hundred microns in diameter, floating particles) as a large brick, PM10 is a small brick, PM2.5 is a small stone pieces. “It like cleaning the front door, large stones should be removed first and then sweep the floor, control of particulate matter, too, should start with the large particles to small particles began to change.”

I that “the fog had not pollution”, followed by fog, “Actually, the” word, as if the fog could evolve into pollution. Fog is a product of condensation of water vapor cold, usually formed during the night, a sun that is scattered, it is fog. Harmful, floating dust constitutes a “fog” should not be called fog, haze should be called. Fog or haze when haze occurs when fog, haze mixed together, this phenomenon should be called haze. Mr. Du Shaozhong said, had not the fog of pollution and air quality pollutants combine and affect the kind of thing is a haze, fog and haze is not fog. Fog is a fog, not pollution had not been nor is pollution.
Mr. Du Shaozhong said, “We are the city twenty-seven point automatic monitoring system.” I wonder if this twenty-seven monitoring point is how to set, is centrally located in the heart of downtown, or in the city within the equalizer settings? If the latter, not only the car bustling downtown with disaster monitoring, automotive few suburbs, such as close to the southern plains and northern Hebei Province, Hebei Province, the mountains are also close monitoring, so that the measured value of a average, of course, air pollution, “minor.” Calculated as the average wage of $ 10,000 and the maximum of $ 1,000 combined minimum divided by two, the average wage is equal to five thousand five hundred. The data so obtained must not “negative”, and sometimes very “positive.”
I said outside the U.S. embassy in the Third Ring Road to the east of Dongzhimen Lufthansa embassy area in Beijing Central Business district. Than in the same city, the place where the U.S. embassy with heavy traffic, especially near the Third Ring Road and Airport Road, the impact of automobile exhaust air should be more serious than the city center. However, the U.S. embassy about three kilometers from Dongzhimen, such a short distance, the difference between air pollution will be significant? Beijing has been the number to six loops, inside and outside the Third Ring Road has become a bustling downtown, so to say, the U.S. Embassy to monitor the air quality there is a certain representation.
on the “fog had not pollution”
Mr. Du Shaozhong said,” We do not get rid of the passive dependent on the weather situation. ” “Relying” refers to God by the wind, Du said the fog – actually haze – blown away, blown to the outside of Beijing, Beijing air will be “clean.” No wind, the air pollution, therefore, “must continue our efforts to increase conservation efforts.” Click here, if the opposite, once we get rid of the passive situation of relying on the efforts to increase conservation efforts do not it?
on PM100, PM10, and PM2.5
November 2,” Beijing Evening News “reporter” dialogue, deputy director of Beijing Municipal Environmental Protection Bureau in Du. ” I think, Mr. Du Shaozhong respond to public questions of air pollution “are negligent to hit.” Missed the dialogue with the Secretary as a civilian, had to write it down. Although Mr. Du Shaozhong see I write the words, hear my voice, but I still say that it write, As for whether others see and hear, regardless. According to Mr. Du Shaozhong following conversation excerpt order of paragraphs, and strike a blow Mr. Du Shaozhong of “negligent.”
Mr. Du Shaozhong said, “The U.S. Embassy is a point, can not evaluate an area”, then the U.S. Embassy in measured air quality can be evaluated at least Lufthansa embassy area to the Northeast Third Ring Road area or air quality. “Area” is “an area.” Our weather, environmental protection departments are attached to the official, by this limitation, the monitoring data can not be too “negative” and therefore not credible. Beijing residents that there is no independent non-official monitoring data, the data can only be used with the U.S. Embassy official comparison. Mr. Du Shaozhong standing official “height”, people willing to understand, should not be “the U.S. Embassy is a point” to a rhetorical public opinion.
such as by Mr. Du Shaozhong the method, first removing large stones and then sweep the floor, slowly passed, calmly, as if deliberately slow down and reduce efficiency. Sweeping should be quickly and efficiently: while removing large stones, while sweeping, which is moving at the same time sweep, sweep, while moving. PM2.5 is a recognized health hazard for most floating particles, once inhaled man will always remain in the lungs, can not be excreted. We should develop PM2.5 air quality standard indicators. According to Mr. Du Shaozhong analogy, sweeping, then, to first remove a small stone pieces – a large stone pieces can escape him, a small stone pieces is not easy to see, and therefore most likely to Ge feet. Controlling air pollution is not “should start with the large particles to small particles began to change,” but rather should develop stringent air quality indicators.
I said three foreign words completely different – PM100, PM10, and PM2.5– about” green technology word “, both the scientific and advanced scientific elite without explanation advanced was heard ordinary people do not know can not read. According to online information: PM100 is one hundred microns in diameter, floating particles, PM10 ten micrometers in diameter floating particles, PM2.5 microns in diameter and two five floating particles.
Mr. Du Shaozhong said, “the fog had not pollution, but it combines a pollutant, it will have an impact on air quality, especially in autumn and winter season, prone to static wind, temperature inversion, which are not conducive to pollutant dispersion weather conditions, so that fog occurs when air pollution is relatively easy to form. “” We do not get rid of the passive dependent on the weather situation, must continue our efforts to increase conservation efforts. ”
development of air pollution and private car (private car) is directly related. Ordinarily, from the reform and opening day, it should be to develop public transport. We are doing exactly the opposite, to develop the private car. When trouble developed private car disaster, the traffic block was a mess, and we started the development of public transport. Earlier development of the private car, public transport development in the post, for the development of the private car is to leave plenty of time. Private car trouble disaster is the culprit of air pollution, and air pollution control and development of the process and pace of the private car is the same. For this development, we allow PM2.5 health hazards, endanger life.
