PM2.5 peak concentration almost equal to 1000 micrograms / cubic meter, which is heavier than air pollution in the process of the last two years,http://www.simu001.cn]ytec-stl.org/]parajumpers femme], are rare. Why the pollution process,http://www.simu001.cn]hiplille.fr/air-max-pas-cher-pour-homme/]air max pas cher pour homme], concentration value so high?MEP and expert analysis, said initial source apportionment show, the entire North region, emissions from coal combustion and industrial processes are the main source of heavy pollution. But Beijing is concerned that the heavy pollution process is mainly based contribution to local emissions, which contribute a larger proportion of motor vehicle emissions."Into the winter, because the coal-fired Beijing and the surrounding area.continued accumulation of pollutants,http://www.simu001.cn]le-millesime.fr/air-max/]air max], causing heavy pollution in this sub-regional process.2 Why did not start red warning?Midway improvement in air qualityAlthough the Municipal Environmental Protection Emergency Department has to respond, but many users are still struggling to ask,http://www.simu001.cn]mggqb###/dzx/forum.php?mod=viewthread&tid=7120][第一私募论坛]http://www.simu001.cn]mggqb###/dzx/forum.php?mod=viewthread&tid=7120],http://www.simu001.cn]pitchforce.co/]chaussure femme pas cher], why the heavy pollution process lasted five days but did not start red warning? Whether the current round of pollution has reached the start red warning standards?In this regard.
The correlation coefficient above 0.95,http://www.simu001.cn]glenlocharsoups###/]hollister california], reflecting the important area of influence of coal-fired pollution. Especially the recent snowfall in the northern region of the cooling process, resulting in a substantial increase in the regional coal-fired heating consumption.According to related statistics, Hebei Province,http://www.simu001.cn]hiplille.fr/air-max-bw-pas-cher/]air max bw pas cher], local coal powder burning and direct-fired straight row obvious impact on air pollution,http://www.simu001.cn]airmaxjordan.es]air max baratas],http://www.simu001.cn]idaahk###/home.php?mod=space&uid=179600][第一私募论坛]http://www.simu001.cn]idaahk###/home.php?mod=space&uid=179600], Hebei Living with bulk coal emissions account for more than 50% of the province's total emissions from coal-fired.In addition, low visibility weather conditions,http://www.simu001.cn]airmaxjordan.es]nike tn air],http://www.simu001.cn]ciscoclub###.cn/home.php?mod=spacecp&ac=blog&blogid=][第一私募论坛]http://www.simu001.cn]ciscoclub###.cn/home.php?mod=spacecp&ac=blog&blogid=], road congestion exacerbate reduce fuel efficiency, but also a significant increase in vehicle emissions. Chai CDCC introduced, especially in Beijing and other urban areas, vehicle density,http://syrup.mints.ne.jp/diary/diary.cgi?command=read_message&msgnum=230/], high activity intensity, a large amount of low-level emissions of pollutants,http://www.simu001.cn]cadovino.fr/barbour-pas-cher/]barbour pas cher], contribute greatly to the local PM2.5 concentration.Special climate and extreme weather as an important incentiveIn addition,http://www.simu001.cn]hiplille.fr/nike-tn-2014/]nike tn 2014], the special climate background and extreme weather conditions,http://www.simu001.cn]glenlocharsoups###/]hollister homme], but also important causes of the current round of North China haze. 2015 is a historical statistics since the "strongest El Nino years," North China in November several heavy snowfall,http://www.simu001.cn]benefitsme.co/]abercrombie france],http://www.simu001.cn]ww32399###/home.php?mod=space&uid=67972][第一私募论坛]http://www.simu001.cn]ww32399###/home.php?mod=space&uid=67972], the snow leading to ground humidity close to saturation, temperature decreases, while the middle atmosphere over the same period was significantly warmer air heat down in the vertical direction "on cold "caused by reduced mobility.
as well as urban and rural interface, scattered burning regulation is not in place in rural areas,http://www.simu001.cn]campcanineusa###/casa.asp?page=abercrombie-roma/]abercrombie roma],http://bbs.qilongzhu.playcrab###/home.php?mod=space&uid=295099], coupled with the increase in emissions from heating boilers,http://www.simu001.cn]marcelbaey.fr/?cat=8]jordan pas cher], these are the causes heavy pollution weather." China Environmental Science Vice President Cai CDCC explained.From the observational data, organics,http://www.simu001.cn]le-millesime.fr/nike-tn-requins/]nike tn requins], sulfate, black carbon and other substances and directly related to coal combustion, is the main component of PM2.5, and also proved that coal is the primary source of lead pollution in North China this wide range of heavy air pollution .Beijing Environmental Protection Monitoring Center judged,http://www.simu001.cn]westsidemedia.co/]barbours], composition of PM2.5 monitoring data from view,http://www.simu001.cn]poppolu.it]woolrich donna], this period of heavy pollution, coal pollution emissions relatively close relationship with organic matter, sulfate, chloride, the concentration of black carbon and other growth curve substantially fully synchronized.
a wide range of North China in the" high humidity "" low speed "" strong inversion "extreme adverse weather conditions, boosting the pollution continues to accumulate.Zhang Dawei,http://www.simu001.cn]cadovino.fr/barbour-france/]barbour france], director of the Beijing Municipal Environmental Protection Monitoring Center said that the current static stability continued high humidity weather conditions, but also conducive to conversion to gaseous pollutants particulate matter,http://www.simu001.cn]idpeng###/zhidao/question.php?qid=18467][第一私募论坛]http://www.simu001.cn]idpeng###/zhidao/question.php?qid=18467], as well as hygroscopic growth of particles, but also increased the concentration levels of PM2.5.Chai CDCC also believes that with the two January 2013 and February 2014 compared to the heavy pollution weather, the weather conditions encountered even worse. Since entering November, North China suffered repeated heavy snowfall weather, making a wide range of North China in the high humidity, low wind speed,http://211.86.128.2/gjjl/Review.asp?NewsID=595], extremely strong inversion of unfavorable weather conditions.
