from 2013 March to 2014 March ", Beijing for 3 consecutive days or more visibility to less Cheap Ole Miss Rebels Jerseys than 3 km of severe haze pollution incident has occurred 18 times." Academician of the Academy of Sciences, Chinese Chinese Academy of Sciences vice president Ding Zhongli said, this means that, in the past year, Beijing average every 20 days there is a haze lost city.
but when the whole society have asked why the sky no longer is transparent, but few people are concerned, the reduction measures really put in place? Pollution control device production enterprises and how much is in normal operation?
not long ago, Premier Li Keqiang said in NPC and CPPCC, 2014 is expected to eliminate the iron and steel production capacity of 27000000 tons, 42000000 tons in the cement industry, flat glass 35000000 TEUs, coal 50000 sets of small boilers; coal-fired power plant desulfurization transformation of 15000000 kilowatts, denitrification transformation of 130000000 kW, 150000000 kW dust modification, elimination of yellow sticker vehicles and old car 6000000. Cheap USC Trojans Jerseys This a good air clear blueprint for people to wear masks sketch.
but the implementation than planning is difficult, the crux of the problem lies in supervision. Ding Zhongli tells a reporter, if every year to carry out Cheap Boise State Broncos Jerseys according to Cheap Notre Dame Fighting Irish Jerseys the government work report of the emission reduction efforts, coupled with the already completed the elimination and reconstruction work, only need 4 years of domestic coal-fired power plant desulfurization and denitrification transformation. "If there is an implementation of list, to see where the government and enterprises to truly do what, what also only stay in slogans stage, or is still a muddled account." Ding Zhongli said.
haze formation: the internal cause is the basic
"now many people ask is what reason creates a haze, in fact the problem itself is not scientific, because the area is a great difference Cheap Kansas State Wildcats Jerseys between the." Ding Zhongli said.
Genesishaze is affected by two factors. One is external, that weather conditions. In calm weather, the air is not prone to horizontal flow, the spread of pollutants is difficult. The external cause is the basic of uncontrollable factors.
on the other hand, the internal haze formation is the emission of pollutants. "Our industry, traffic will emit gases, these gases and atmospheric composition Union, solid material into transformed by complex process called two particles. The pollution caused by heavy pollution, heavy haze particles most is not directly discharged, but two particles." Ding Zhongli said. In Beijing, the main source of haze is coal and motor vehicle emissions.
The maincoal has power plant plant, boiler, coal chemical industry and residents, the main pollutant is particulate matter and sulfur dioxide.
had earlier media reports have contributed to the PM2.5 vehicle is less than 4%. To this, Ding Zhongli points out, 4% is only a proportion of emissions, does not contain the gas pollutants contribute to the formation of PM2.5 two particles. According to the Beijing Central ASTRI Beijing on air pollutant emission inventory data, on nitrogen oxides and volatile organic compounds, the proportion of motor vehicle emissions were as high as 42>
