coal,piumini peuterey, biomass burning, vehicle exhaust and waste incineration, industrial pollution and secondary inorganic aerosols, the average contribution of these sources are for 15%, 18%, 12%, 4%,t shirt abercrombie, 25% and 26%."This study itself can not be wrong." CAS "chase due to atmospheric haze and control,peuterey donna," explained HE Hong, chief scientist to the special correspondents said, "Please note that there is a secondary source parsing inorganic aerosols, there is very Most of the gas conversion of motor vehicle emissions. In addition, a considerable part of the secondary organic aerosol emissions from motor vehicles also. "HE Hong said that to accurately explain the "secondary aerosols.
" the source, there is not. He believes that "secondary aerosol" formation mechanism is not entirely clear what the current Chinese haze "mechanism is unknown,woolrich giubbotti," the key."Secondary aerosol"Secondary aerosols accounting for most of the PM2.5 in. "It is through our 16 sites, two-year analysis, the haze around to secondary aerosol-based." Trolling Zhang, vice president of the China Meteorological research told correspondents.The research on the aerosol began around the 1990s. Zhang drag from the beginning of 1989 has been committed to research aerosol, is one of China earlier in the aerosol research scientists. He is also the national "973" plan "and its climatic effects of atmospheric aerosols" and chief scientist "Aerosol - Radiation feedback process and its interactions with the Asian monsoon - cloud" project.Zhang drag to correspondents explained that the air can affect the visibility of the substance.
there are two, namely,moncler shop online, particulate matter and water droplets. Particulate matter is aerosols. According to the definition of meteorology, haze is a lot of very fine dust and other dry evenly floating in the air, so that the horizontal visibility is less than 10 km turbid air universal phenomenon. Here's the dry dust refers to dry aerosol particles.Cloud refers to water droplets suspended in the air,louboutin femme, when it reaches the ground,abercrombie france, also known as fog. However,peuterey uomo, if there is no condensation nuclei, in the actual air cloud can not be formed. When more water vapor in the air, some absorbent absorbent dry aerosol particles will grow up and eventually activated to cloud condensation nuclei,moncler milano, if a lot of pollution particles, it will produce more and smaller cloud droplets, so that visibility further reduced when less than 1 kilometer is defined as fog,woolrich, mist and the visibility is defined as the time from 1 to 10 km.Therefore, no dry aerosol particles can not form haze, no involvement in the actual atmospheric aerosol particles are also unable to form fog.Zhang drag further explained that, because of the fog and haze can affect visibility, so the visibility is less than 10 km, it is sometimes possible contribution of both the haze, but also the contribution of the fog. Haze and fog can change roles in the day.
even in different places in the same area, fog and haze will be emphasized. Under normal circumstances, we see that while there is the presence of haze and fog,louboutin femme pas cher, visibility is less than 10 kilometers of regional air generally turbid phenomenon is called "fog - haze" weather.Zhang told correspondents drag,outlet peuterey, through the relationship between visibility and aerosol Our analysis found that nearly three decades of increasingly serious problem in eastern regional haze, mainly by anthropogenic emissions of atmospheric aerosols significantly increased. He said that in the past also easy to produce fog in the mountains, the condensation nuclei are organic carbon particles produced by volatile organic compounds vegetation ultimately formed,giubbotto peuterey, not the amount. Now fog condensation nuclei, mostly anthropogenic emissions,abercrombie, large and harmful. Atmosphere at the same liquid water content,moncler bambino, as condensation nuclei much more easily formed but a small quantity of water droplets. These droplets quantity and small, stayed in the air for a long time.
long life,peuterey online, less likely to rain.Since 1980, China's increasing anthropogenic emissions, fossil fuels,giubbini peuterey, biomass burning increases, land use and cover change, causing the air to rise sharply primary and secondary aerosols.Zhang drag explained,giubbotti moncler, aerosol refers to a direct discharge into the atmosphere from sources of aerosol particles, the second aerosol is discharged from the gas discharge source is converted to produce an aerosol, a secondary aerosol composition of the aerosol There are some differences. His research team has some findings regarding secondary aerosols.
