    <p> Interpretation III: chemical reactions do evil. Yuesi called "SO2 pollution emissions (sulfur dioxide) gas, NOx gases (nitrogen oxides) people can not see with the naked eye,sito nike, only satellites or instruments with special" eye "can see, the key is to SO2 and NOx gas once gas becomes sulfate and nitrate particles, people will be able to see them, and this is what we call "haze" of pollutants. "According to the results of the analysis of continuous observation in January, the 11th Air PM1 (PM2.5 accounts for 70% to 80%) than in sulphate pollution have not exceeded the same period rose 25-fold,veste barbour homme, 20-fold increase of nitrate, ammonium increase 22-fold,imitation louboutin pas cher, 10-fold increase in organic matter; the whole PM2.5 maximum value of the instantaneous value of 800 micrograms / cubic meter (h average 500 micrograms / cubic meter),chaussure tn pas cher, "Yuesi said. "Sulfates and nitrates,nike air max, the most important reason is that they are soluble in water, very hygroscopic, very small particles can not see it (the human eye can only see particle size & gt; 0.4 micron particles), but If these ultrafine particles containing sulfates and nitrates will absorb water, a water-absorbent becomes 'fat' fat to 0.4 micron (400 nm) or more, people will see it (haze mix); urban vehicle emissions The fine particles (carbon particles) peak at 200 nm, people do not see,moncler italia, sunny air humidity is low, the wind diffusion quickly, when the weather humidity static stability and large,abercrombie france, especially industrial emissions of SO2 absorbed quickly It will increase to 400 nm or more, into the people's attention. 5 How to understand the exponential "burst table"? Burst table, this means that the instrument pointer exceeds the limits shown in the table. In recent days,veste moncler homme, the science vocabulary is frequently used domestic media,louboutin site officiel, the cause is the US Embassy in Beijing to monitor themselves.</p>

    <p> PM2.5 monitoring points near instantaneous concentrations reached 522 micrograms / cubic meter,barbour pas cher, the corresponding air quality Index (AQI) has exceeded the upper limit,peuterey donna, namely a "burst table" situation. However,tn air max 2014 pas cher, according to news agency reports, the Beijing Environmental Protection Monitoring Center officials said, in the field of professional monitoring, no "burst table,parajumpers homme," the word,hollister italia, but some instruments can manually set a maximum range, but the official did not disclose PM2.5 monitoring instruments maximum range. 6 Such a high index of health, what harm? Information about the PM and human health has been the focus of academic and media attention. "Overall Environmental Science" has been published in a medical professor at Peking University School of Public Health and colleagues Pan Xiaochuan new discovery: the period from 2004 to 2006, when the observation point PM2.5 campus of Peking University, In about four kilometers outside the Third Hospital of Peking University,barbour catalogue, the number of emergency room patients with cardiovascular disease also increased. Although PM10 (particulate matter in the atmosphere in diameter less than 10 microns) and PM2.5 (diameter less than or equal to atmospheric particulate matter 2.5 microns) are risk factors for cardiovascular disease,air max femme, but the impact of PM2.5 clearly greater. In addition,soldes louboutin, a report from the United Nations Environment Programme, said, PM2.5 concentration of 20 milligrams per cubic meter rise,nobis jackets, China and India will be about 34 million deaths each year.</p>
