What are the causes of air pollution in Beijing?

Hi guys, I was wondering if anyone could give me some in depth Information about the causes of air pollution in Beijing. I know the causes are: traffic (Cars,buses), Construction, Burning of fossil fuels, dust storms, Factories and the mountains

but do you have any good in depth information or websites,, please please help me

thankyou so much

Update:

Does anyone have any good statistics or really good websites?

Update 2:

Hi JBQS, i was just wondering where you got your information from so i could look further into it?

    So those evil white devils are making all Air China buy all those polluting airplanes and forcing Chinese drivers to contaminate the already toxic atmosphere, eh cao hao? Hilarious!

    Is mainly the massive destruction of vegetation in northern China, resulting in desertification. The other hand, emissions of carbon dioxide lead to decline in air quality

    the key component to Beijing’s ozone problem is actually volatile organic compounds (VOCs) from small factories in neighboring Hebei province.

    Most of the problem with the pollution in Beijing is that it is expanding faster that it can modernise or up grade its factories, power stations etc.

    An example is that 10 years ago, WudaoKuo a popular student handout today, was nothing more than a little orbitally village on the outskirts of Beijing. When the subway was build it it expanded like mad and today it is part of Beijing. As shown from the photo from the subway station.

    This is a pre-2008 games photo. The bus lanes have been added by now.

    The problem back then most of the power plants where build outside of the city, as the city grew, residence areas have growth and merged with the factories and power plants. If you take a walk around WukaoKuo and around Tsinghua (QingHua) campus you will come around many sub coal fired power stations. In the colder months they will fire up, plus polluting the area, it can be so bad at some times (due it the cold air bringing the pollution back down to Earth) it can sting your eyes not to mention the smell of burned oil...

    In many cases to supply Beijings ever growing demend for power it is a lot easlier to build another coal fired sub station, than it is to upgrade them. Only in the last couple of years is Beijing starting to take note of this, in game year they order most of the factories to shut out. Also they have moved one of Sino steel's biggest factory away from Beijing not to mention that more and more people are buying cars as they can now afford them.

    However defining how good Beijing air quality is has come under criticism of "faking" the results as they have lately changed the air sampling methods and result. Taking fewer samples and closing bad ones in bad areas.....

    The main causes of air pollution in Beijing are so many of cars and airplanes,but both of two were released by westerner from that Pandora's box.

    the country uses too much dirty cheap coal.

  • 1 decade ago

    "Coal is the number once source of air pollution in China. China gets 80 percent of electricity and 70 percent its total energy from coal, much of it polluting high-sulphur coal. Around six million tons of coal is burned everyday to power factories, heat homes and cook meals. Expanding car ownership, heavy traffic and low-grade gasoline have made cars a leading contributor to the air pollution problem in Chinese cities.

    "Kinds of Air Pollution

    "Air pollution includes particles of soot, organic hazardous material, heavy metals, acid aerosols and dust. The smaller particles are more dangerous because they are more easily inhaled. Judged as the most dangerous for health, suspended particulates are caused mainly by coal and car exhaust. In the cities it is also caused by construction. In the spring it is caused by dust from the sand and dust storms in the Gobi.

    "Particulate matter, which includes dust, soot aerosol particles less than 10 microns in size is a major source of air pollution. Particulate levels are measured in micrograms be cubic meter of air. In United States levels about 50 micrograms are considered unsafe. In Europe the levels are around 40 micrograms. In Beijing that average level is 141.

    "China is the world’s leading source of sulfur dioxide. Levels of the pollutant in the air are comparable to Japan in the 1970s when air pollution was a major problem there. Emissions of sulfur dioxide from coal and fuel oil can cause respiratory and cardiovascular diseases as well as acid rain. Sulfur dioxide emissions alone are though to cause damage equal to 12 percent of China’s GNP.

    "Nitrogen dioxide is not a serious problem. Levels of the pollutant in China are comparable to those in Japan. Even so levels in Beijing rose 50 percent between 1996 and 2006. Nitrogen oxide is released by power plants, heavy industry and cars.

    "There are also problems with ozone and paticulates measuring more than 2.5 microns. Ozone forms when nitrogen oxides combine with hydrocarbons emitted by vehicles and refineries. It affects photosynthesis. High ozone levels recorded in the lower Yangtze basin are thought to be linked o crops yields that are 25 percent lower than those in unpolluted areas."

    From another source:

    "Contrary to popular perception both inside and outside China, Beijing’s air pollution problem is not primarily due to increases in personal vehicle use. Granted, there have been dozens of press reports about the surging numbers of vehicles that Beijingers are buying. These reports are true, but also misleading. In contrast to the experience in the U.S., Beijing’s boom in vehicle ownership has not yet invaded its surrounding areas. It is mainly China’s wealthiest cities that are participating in the car boom; smaller cities and towns have seen more modest growth in vehicle ownership.

    "The real causes of Beijing’s air quality woes lie elsewhere. An article last year suggested the key component to Beijing’s ozone problem (the stuff that makes your eyes itch, causes shortness of breath and reduces visibility) is actually volatile organic compounds (VOCs) from small factories in neighboring Hebei province. A sniff test suggests that there are plenty of these factories operating in and around Beijing. Many are small (and possibly illegal), and they operate only at night to avoid the scrutiny of environmental inspectors. So the Beijing government has several problems: first, it must locate these hidden factories. Then they must shut them down—and convince neighboring provinces to do the same.

    "Beijing’s other major problem is particulates, which come from several sources. One is construction: Beijing is still rushing to complete non-Olympic buildings before the big day. Another is coal-fired power plants and factory boilers. China’s largest coal-mining province, Shanxi, is directly up wind of Beijing. Shanxi ships much coal to other provinces, but it also has mine-mouth power plants and coking plants that contribute to regional pollution.

    "A final source is trucks. As with the VOCs from small factories, emissions from heavy vehicles are worst during the night, since trucks are banned from the city during the day. Studies have shown that Beijing’s pollution levels are highest in the early morning. This would not be the case if most of the pollution came from passenger cars, which operate mainly during the day. But it is good evidence that the chief sources of pollution are the VOC-producing factories and trucks operating at night.

    "The international focus on Beijing’s car problem, when the true problem lies more with industrial emissions, suggests we often apply lessons from one place a little too readily to another. China’s air pollution problem—like its [greenhouse gas emissions](node/9331)—is primarily connected to industry. There is no question that smart transportation planning would help China avoid vehi
