Shanghai PM2.5 data the fastest release next month
□ Evening News reporter Kong with reported
two consecutive days of light pollution of the air quality, with rainfall finally today was reversed. Morning, the Shanghai Environmental Protection Bureau for the whole guest Xinhua News Agency Yangtze River Delta News, Radio and Television Broadcast News, Evening News, LONDON, jointly organized the “2012 Shanghai Minsheng Interview” program. Zhang Secretary said that the response to atmospheric pollution in Shanghai will be possible to develop the standard of motor vehicle “Shanghai V, on the dust impact on air quality issues raised by the reporter, the Secretary to respond to: monitor the head will be installed on the new site, and introduced prizes to report environmental violations, and welcome to all the people to participate in the supervision and environmental protection work.
welcome the public to report black smoke vehicle
Chang-chuen said, in fact, environmental protection has now entered a stage of relatively protracted war. Such as black-odor river, basically to the eutrophication stage; everywhere black chimney, and now to the stage of concern for PM2.5. “We focus every year, every year, this year our focus is to take the fifth round of the environmental three-year action plan fully deployed, landing a lot of the public can feel things, such as emission vehicles within the inner ring black smoke car has been very little. “
Zhang in particular through the” people’s livelihood interview appealed to the public, welcomed the report of black smoke vehicles. “In the past, more time, we report, however, is indeed rare, less then stare at it, we have to control the outer ring, this can be effective in 2012.”

PM2.5 monitoring sites can not put the park
in last year’s “people’s livelihood interview program, Zhang first time it comes to PM2.5 in time, many people do not know what PM2.5 is now the most ordinary Shanghai residents PM2.5 is a human lung particle data as a professional, the Shanghai municipal government report this year will also PM2.5 write in.
mentioned in the government work report will be released in the first half of the PM2.5 monitoring data, noted that, since the beginning of this year, Shanghai is in accordance with the original plan, redoubling its efforts to site construction. May, these new station and 20 stations originally built for network debugging, to June with the basic conditions of the officially released hardware and software, in addition to some training.
of PM2.5 in the short become a hot spot in the short year, but whether it is a how to, how to monitor how governance will also need technical and policy including the development of legal standards of PM2.5 monitoring first distribution, Zhang said: “We want representatives of the various functional areas of a city to find out, neither entirely on ambient air quality is relatively good, but also on the relatively poor. “This means that the monitoring points can not be on the park can not be completely on the side of the road or the factory, according to the provisions of national standards to control point, which is divided by the relevant national technical departments, which means that when a city development to a state, how the distribution. Zhang Quan said: “With the further development of the next city, you may also adjust these points to be able to represent the production and daily life and activities of the entire city.
of PM2.5 fine particles below 2.5 micron, automatic monitoring of internationally accepted methods are two: one is called a beta ray method called shock balance method from the current international and several domestic current level and largest professional pilot, but also in the standard way to add a compensation, to exclude some of the example, disturbances such as humidity, temperature is more complex due to its source, the future governance more difficult to monitor the work itself or to provide for future research and treatment of scientific data.
Zhang Quan, dust, vehicle exhaust, straw burning PM2.5 “contributions” are all very big. like Shanghai a large cities, PM2.5 monitoring early part of the preliminary scientific research. “Shanghai’s major source of PM2.5 in the first motor vehicles and vessels, the ship also, as well as aircraft have, which we judged account for about 25%, this source is relatively large, mobile sources; The second is the process of all industrial enterprises, industrial combustion processes, more enterprises in Shanghai, probably accounted for about 25%. These two parts accounted for 50%. Third dust, road dust of the site, including yard, probably accounted for about 10%; the fourth power plant, now power generation by coal-based, and also accounted for about 10%; other agriculture, civil, such as the hotel every household cooking have of PM2.5, but this coming together has a certain amount, including straw, although it is seasonal, but emit in two seasons, this part is probably also accounted for about 10%. In addition, there is interaction between the 20% of the area, which involves the joint prevention of the Yangtze River Delta region.
new site to be installed a video probe to monitor the dust
site dust pollution and only 10% of the PM2.5 emissions, but it is around us, it is not industrial enterprises the kind of industrial enterprises can not get rid of in the short term, structural adjustment, governance is a long process. Site dust is actually on the side, there are a large number of other export flow, both physical and mental health of people, or the image of the city, must govern. “
Zhang whole revealed that the Environmental Protection Agency is to discuss diplomatic relations committee and the district, want to further tighten the dust management from several aspects. Evaluation of dust through the monitoring of dustfall, that is, after assessment methods, Zhang said with a smile: “But now we want to month review time seems to have a problem, because the pollution has caused, so we need a dynamic.
the future, for the new site will want to install video surveillance cameras, and site dust of the house into the site rules of law. “No matter you are not monitoring this dust super is not excessive, is to provide action you have to do some action, action to do in place. Such as tire out must rinse this one to see through the surveillance camera that we have public participation, and also to welcome the people to report. For the public to report real name without the environmental approval is illegal to start the construction of industrial projects, six categories of environmental violations, a verified will receive a reward of 1,000 yuan to 10,000 yuan in the yard on the issue, the dynamic regulatory and full coverage from their own to do the operation and management of the fine.
dust are often derived from the road, a conveyor belt, there is a road next to the green. “in the green early time in some places a little problem, but most are good, dirt, and then did not block the rains came down. “Zhang Quan said,” street washing, during the Expo strength is very high, the road early in the morning, night to rinse the future, we need to linkage and meteorological departments, such as it does not rain today, two days without rain, necessary to regularly wash.
motor vehicle pollution in some areas accounted for 76% of air pollution
now Shanghai car ownership is very high, sooner or later, the peak air quality flattered when a reporter to Zhang Quan motor vehicle pollution control issues, noted that most of the indicators of the downtown areas of Shanghai air pollution from motor vehicles, motor vehicle pollution in the city center of the air pollution inside the “contribution” is probably 50% -60 % in some areas even up to 76%. Zhang Quan, first and foremost in the city has a monitoring network under the premise, of course, not just of PM2.5, also other pollutants such as sulfur dioxide, nitrogen oxides, ozone, there are some special pollutants have monitoring. smooth flow of traffic congestion and our air quality is very relationship, which in fact does have a certain regularity.
to solve the problem of motor vehicle pollution, which is a very huge project. “First of all, any one region and the city needs to have a big traffic strategy, the framework must be appropriate, must be correct. Such a high density like the mega-cities, the first development of public transport, in particular, to develop rapid, low-carbon subway system, this is in the affirmative. This is like the source of pollution, this is the first level is the motor vehicle pollution control, you have to do a motor vehicle, the first traffic framework of reasonable and unreasonable. Zhang Quan said.
in terms of governance, new car based on the socio-economic conditions, as soon as possible a higher standard. Zhang Quan said that Shanghai is the next step to go before the State Ⅴ standards for motor vehicles, if the country standards did not come out, and now no way to adopt the subject, that in Shanghai will advance the implementation of the “Shanghai V” standard, similar to Beijing, “Beijing V”. “We intend to fight to be reflected in the next year. “By this standard, the so-called” national oil and cars are two mutually conditions of the premise, what kind of car is the oil, after the implementation of the new standard, we must consider oil and automotive synchronization.
Ⅴ standards equivalent to EU Europe Ⅴ standards, more stringent restrictions on motor vehicle emissions of nitrogen oxides, hydrocarbons and other implementation, the European Union from 2009 onwards, from the country I mentioned to the country IV each increase a standard bicycle pollution reduced by 30-50%. using the new standard for gasoline and diesel emission reduction a number of pollutants, reduction of PM2.5 emissions from the country Ⅳ country Ⅴ, environmental protection and other indicators are further tightened, including the sulfur content from 50ppm down to 10ppm, oil quality is further improved.
study results show that the automotive gasoline and diesel quality upgrade contribution to emission reduction, substitution of the fifth stage the fourth stage motor gasoline and diesel achieve at least 10% and 7% of the nitrogen oxides emissions of hydrocarbons, carbon monoxide, nitrogen oxides, particulate matter emissions will be effectively controlled after the implementation of the new standard, the sulfur content of fuel is only a fifth of the previous improve due to fuel quality, combustion will be more fully, you can directly reduce emissions of PM2.5 in the exhaust.
Shanghai because
Shanghai is out of the 230,000 high-polluting vehicles more enterprises, but also a port of major cities, transportation, more than the freight car, Shanghai is now there are 230,000 high-polluting vehicles, more than in Beijing. “230 000 cars, we want to use the boot mechanism to speed up elimination. New for old policies to accelerate the elimination of the public security department to discuss, ready to have to have some mandatory measures, the international passage. Car of high pollution, the local government can develop some of the control area, would not let him come in, this can speed up the elimination. Zhang Quan said.
addition will be the implementation of the IM system, monitoring and maintenance system, the safety inspection, such as driving to the annual inspection, the inspection will be carried out the inspection of the vehicle exhaust qualified talent and other indicators together, the payment of annual inspection of books, unqualified going to repair. Zhang reminded that: “The drivers should know a thing. Exhaust standards are not standards, for individuals like you is routed to the outside, but if we do not pay attention, the entire environment look very bad.
the[water safety
sensitivity of
study, after the advance higher early warning system
With Qingcaosha water source, the Shanghai drinking water source security is greatly improved, but not there are hidden dangers? Zhang Quan said, we want the warning line of defense is more careful. "Qingcaosha What are the benefits? If the upstream leak, as long as we are able to know ahead of time, there is a way to close the gate, and then water storage, water storage a long time, there can be 68 days. This requires that we have a very sensitive, ahead of larger warning system monitoring. This early warning system, with the water supply, including maritime research, city leaders we also have instructions to step up research in this area, so our monitoring network in advance, and more dense.
Shanghai on the Yangtze River downstream, In Zhenjiang upstream pollution incident this year when the Jiangsu environmental protection department in a timely manner to send us the information carried Bulletin. "In the future we need to strengthen information sharing in this regard. Once the upstream thing, let us know.
in fact now the implementation of national standards have been more strict now tap water should be more than 100 indicators, previously only 30 a number of indicators, as monitoring is more rigorous, more high level. " This is beneficial to the health of the people, the safety of drinking water. The safety of drinking water is actually related to water, flood control, water to the faucet, this is a system-wide process, there are now conducting a number of landmark transformation, water tanks and transformation of a series of work can improve a city's safe drinking water. Zhang Quan said.
[transformation]
Forced mechanism to help enterprises in transition
Yangtze River Delta economic development is very fast, many factories and enterprises. industrially developed countries is a good thing, but is directly caused by the impact of environmental vulnerability.
Zhang noted that the developed eastern regions in addition to the end of treatment, but also to consider more source of industrial transformation. ” In fact a few years ago, Shanghai has started doing. In recent years, annual adjustments to the almost 700, some high-energy, high-polluting enterprises in the ongoing structural adjustment.
Chang-chuan, Forced mechanism in the development of transformation. “Forced intensity should be appropriate, neither too far ahead, can not fail to focus on. To promote law enforcement and environmental protection and strict access and elimination of high-polluting enterprises, Forced it to make the transformation. Environmental protection of this function, the last round of reform is clear, a more positive macro-participation. “In addition, macroeconomic coordination, environmental departments often and Reform Commission, the Commission by letter, co-ordination.
in the suburbs, there are some companies do not meet our regional distribution and industry-oriented, this will be resolutely eliminated. Zhang Quan, said some companies subjective environment trying to do a good job, but do not accidentally make a mistake, excessive emissions, but some companies are actually malicious. “our country the law is very clear on the subjective willful and serious impact on the environment, it is necessary to bear the legal responsibility of legal persons and units have more stringent handling, and even be held criminally responsible.
[consumer]
against excessive packaging
regardless of enterprise level conversion, or to carry out rehabilitation measures in environmental protection, the final analysis, environmental philosophy enjoys popular support, let the people start from their own point of view, told reporters “people can do to help green” issues, Zhang Quan said with a smile, fact, environmental protection and ten, there is a The great difference is in the public participation is now more dependent on the joint action of the whole society, previous bottleneck in investment and government relations with the people is not too large. However, the development to this extent, I think that really need more of the whole society to act together.
this year, “6.5″ World Environment Day theme is “green consumer” is not excessive packaging excessive packaging “green consumption” and one is how to curb against excessive packaging. Hazards very obvious waste of resources, pollute the environment, these resources, manufacturing will be emitted to damage the interests of consumers, and even related to business interests. Zhang Quan said, the recent National People’s Congress also promote the legislation, but also a standard, they can do a lot of , including price express, even if excessive packaging, can sue the producers to unfair competition and fraud.
field survey
mild air pollution monitoring engineers tension
several days of mild air pollution in Shanghai Environmental Monitoring Center engineers also followed tense for several days. Yesterday afternoon, the instantaneous converted to 6 m/s from 1 m/s wind speed in the morning, the wind is southerly, the air quality immediately improved. “If it is not the afternoon improved air quality, I have no space to take you look at the automatic monitoring stations. Nandan Road, the roadside air quality monitoring stations, the daily air quality forecast group chief forecaster Lin Chenyuan laugh a sigh of relief, told reporters.
Stations roof, a solar power next to the light board, in addition to being wind, weather instruments, the most eye-catching three air sampling head, they are constantly inhaling various substances in the air, and through automatic monitoring stations within the instrument data directly sent to the Environmental Monitoring Center on a computer screen Linchen Yuan told reporters that the air quality numerical prediction model is the first using the current forecast model, using the meteorological model coupled with pollution models, six different forecasting models often estimate different results. “On this basis, but also add on our experience and judgment, such as dust impact, these forecasting models do not work a. Linchen Yuan said, “Of course we also forecast insufficient, the overall prediction accuracy rate of about 80%.
from the past, people concerned about the weather conditions, to today’s concern for air quality forecasting changes in their living environment more and more attention in the daily air quality room, several large screen different data from more than 50 automatic monitoring stations in the city. several engineers are busy to discuss the impact of weather conditions on the day Shanghai is air. “In fact, the local dust, the most important change from the weather conditions. . Linchen Yuan said, “We and the meteorological department, linkage, and sampling the results of the United States, Europe, Japan and China, local weather forecast, forecast daily air quality conditions. “
