Haze in the of Beijing forbidden city. information figure Beijing city EPA monitoring of air quality data and United States Fake Dolce & Gabbana Handbags Embassy of monitoring data inconsistent, "Nanjing meteorological" official micro-Bo publishing "PM2.5 subtle particles property concentration" number hours Hou delete, environmental Department publishing environment air PM2.5 determination specification, second times sought views Shi will PM2.5 into general air quality evaluation …… in recent days to, every time PM2.5 in news in the appeared, are raises has widely concern. China has one of the particulate emissions in the world's most polluted, while the PM2.5 most harmful to human health and the atmospheric environment. Rave PM2.5 why raised concern? how to treat the Chinese release of PM2.5? for decades has been engaged Fake Dolce & Gabbana Handbags in the environment of the Chinese Academy of engineering monitoring technology interview with academician Wei Fusheng Morning Post reporter yesterday. Wei Fusheng was born in 1938 in Sichuan Jianyang County
In 1964, graduating in Department of chemistry, University of science and technology of China, staying in school to teach. redeployed in May 1983, China national environmental monitoring centre. Analysis Research Office Director, the monitoring centre has served as Deputy stationmaster, researcher and Chief Engineer. Last century 70 's, he began to carry out environmental monitoring and analysis of technologies and methods of research, to establish and develop techniques and Fake Dolce & Gabbana Handbags methods of environmental monitoring system in China has made important contributions. He was concerned about the environmental pollution and health research in the last decade, and the United States a number of collaborative research, such as "effects of air pollution on respiratory health research", "PAH''s and lung cancer risk assessment of exposure and its metabolites", a series of important results have been achieved. in 1997, he was elected as academician of Chinese Academy of engineering. Autumn, light wind is light, autumn is the best season in Beijing. However, since the beginning of October, Beijing was often clouded, blue sky and white clouds rare. Meanwhile, the United States Fake Dolce & Gabbana Handbags Embassy pursuant to
Its a stations published many times in the Embassy building in Beijing air quality index, reached because of the PM2.5 number more than 200 "very unhealthy" level has caused wide concern. Although Beijing authorities explained that the US Embassy released a data not representative of the whole city, United States Embassy also known as Beijing announced its numerical and value of "no comparison", but with the residents ' worries and concern about air environment around, one has not been widespread concern terminology came into the public eye--PM2.5. On November 1, the State Department of environmental protection, for the first time on PM2.5 measurement method by Fake Dolce & Gabbana Handbags standardizing. on November 16, the Ministry of environmental protection informed the relevant person in charge, starting on the same day to the second public consultation of the whole society, the biggest adjustment was the PM2.5 and ozone concentrations into regular 8 hour air quality assessment, and 24 hour average concentration of PM2.5 year limits are designated respectively as per cubic metre
0.035 mg and each cubic 0.075 mg. yesterday, China engineering homes academician, and China environment monitoring terminus original Chief Engineer Wei Fusheng in accept Morning Post reporter interview with Shi said, if now on implementation PM2.5 standard, 80% of city air quality will does Fake Dolce & Gabbana Handbags not compliance. but, he also think, "this standard although let many local of air quality fell to does not compliance of point, but also also to local government a direction, to developed resolved of approach." Wei Fusheng also claimed that the standards are not as strict as possible, and should be defined according to China's actual situation. He also said the United States before the formal implementation of PM2.5 has also sparked debate in the environmental sector and industry sector, stalemated for nearly 20 years. Public dissatisfaction with air quality Oriental Morning Post: why PM2.5 drew so much attention? Wei Fusheng: I think first of all on air quality of a discontent. especially Beijing, Canton
Such States, Shenzhen City. because major activities such as the Olympics, Asian Games and the Universiade held over a period of time, the Government has suspended operation of enterprises through administrative means, reducing traffic flow, many sites also stopped construction and so on. these measures improved air quality in a short time, people have felt the quality of air. Major events after the end, the enterprise resumed production, road congestion, bad weather is back, the public has a clear contrast and unsuited. I also deeply understand, blue sky and white clouds of weather is less, it's a fact. Oriental Morning Post: it was observed that air quality is good or bad is not changed because of sense data, the data is a data. so how do we make sense of PM2.5? Wei Fusheng: PM2.5 is fine particles in the air, from a professional speaking, is the dynamics of air particulate matter less than 2.5 microns in diameter. these sizes do not
Packed a particle suspended in the air, almost invisible to the naked eye, the public is difficult to realize that they harm. In General, more than 10 microns in diameter particles, being locked out of the nose; 2.5 microns in diameter to 10 micron particles can enter the respiratory tract, but with spitting, sneezing was partially eliminated from the body, and fine particles of less than 2.5 microns in diameter, has successfully passed through the lower respiratory tract. Small particle adsorption a variety of toxic chemicals. under the same concentration, particulate matter more, more, adsorption of toxic substances in the air will be more. From the environment, on the detection, particles are very small, light the digestion more obvious, PM2.5 is also very important pollutants contribute to our visibility degradation. Measuring PM2.5 Oriental Morning Post, has more than 10 years of scientific research: second request for comments the PM2.5 into regular air
Quality assessment. academics on this do you think? Wei Fusheng: in academia, as far as I know, PM2.5 is more than 10 years out, of course, this is from the perspective of scientific research., in my view, States should be introduced as soon as possible of PM2.5 standards, this standard will help us to change the Government's air quality. Oriental Morning Post: full implementation of the PM2.5 standards why only on January 1, 2016? Wei Fusheng: because conditions are different, involving many, starting with the announcement to implementation shall allow the necessary time to prepare. Furthermore, the preparations for implementing the new standards will be slow, some of these areas the implementation of economic and technological basis for better standards, I think the PM2.5 standard practice may start from conditions of relatively mature urban. Oriental Morning Post: public implementation of PM2.5 standards are growing ever louder, and the Environmental Protection Department is relatively cautious, and why? Wei Fusheng: this is mainly the country
There is no development of ambient air quality standard for PM2.5 standards. this standard is also consulted. If environmental protection Department published privately this may bring some pressure to the local government. According to China's air quality evaluation system, daily mean concentrations of PM10 control at the time of less than 100 mg/m, air quality is good. generally speaking, the 50%~80% of PM10 are fine particles PM2.5, specific to Beijing, took 50%~70% share of PM2.5, PM10. This means that when good is Beijing's air quality monitoring results, daily mean concentrations of PM2.5 is not standard. As far as I know, if the current air quality evaluation system, 80% city air is compliance. PM2.5 air quality in evaluation system, 80% is not standard. PM2.5 is East of social problems
Morning post: local government is a lot of pressure? Wei Fusheng: Yes. that year United States implementation of PM2.5 as well, as far as I understand the United States at that time, the health sector to promote the implementation of environmental protection of PM2.5, and some industrial departments responsible for industrial, automotive, has strongly opposed, stalemated for nearly 20 years. Similarly, in China there is a similar problem. Oriental Morning Post: in your opinion, PM2.5 is not only a scientific issue, but also social problems? Wei Fusheng: represented by PM2.5 fine particles in the air mainly from coal-fired, site and car exhaust dust. industrial production in the coal, sulfur dioxide and nitrogen oxides, generated in the air after a series of chemical reactions of nitrate, sulphate, nitrate and sulfate aerosol. Local Government is not only faced with environmental problems, also faced economic development as well as complex social problems. local government change and air quality, you have to guide the enterprise strategic transformation,
Technology upgrades, improved energy efficiency, reduce vehicle carbon emissions, reduce traffic congestion. Our country is a manufacturing powerhouse, "world factory" pollution in China, exports abroad. place cannot simply close the plant, involve at least hundreds of thousands of such factories of our country, to transform and upgrade, also face these factory workers eat and employment issues. This is easier said than done is really difficult. Oriental Morning Post: this is the extensive development model of pain, but we should face this reality, PM2.5 telling the public what is how much? Wei Fusheng: Yes, there is a painful period. but now is around the corner is not a simple problem. Standards are not as strict as possible Oriental Morning Post: current implementation of PM2.5 standards, what is the urgent need to address? Wei Fusheng: detection technologies and instrumentation we nationally and internationally, and there is not much different, a lot of
