On January 28, 2013, the China Meteorological Administration Forecasting and Networks Division once again promulgated a notice on doing a good job of haze weather early warning. The standards for haze warning signals were revised. For the first time, the PM2.5 concentration reflecting the air quality was compared with the atmospheric visibility, Humidity and other meteorological elements as an important indicator of early warning classification, the same day, the Central Meteorological Station issued the first separate haze warning.
"China Business" reporter learned that increasingly frequent fog and fog forced PM2.5 prevention and control progress accelerated, as more and more areas to join PM2.5 monitoring team, the resulting market opportunities gradually show . Industry estimates, environmental monitoring and analysis industry will be the first to benefit from the next three years, the air quality monitoring instrument market will reach 5 billion yuan.
At present, China's existing market of PM2.5 monitoring equipment, imported equipment accounted for about 80% of the share, but due to long-term lack of monitoring standards based on China's domestic environment, in accordance with foreign monitoring standards for the production of imported equipment widespread "acclimatized" This has won some time for the domestic PM2.5 monitoring equipment, but the mature technology of foreign enterprises is still a powerful competitive weapon in the domestic PM2.5 equipment market in the future.
The latest news shows that China Environmental Monitoring Station, led by the Ministry of Environmental Protection, as a technical support, Hebei Environmental Protection Technology Co., Ltd. precedent (precedent environmental protection: 300137.SH) as the project leader in the development of China's major national environmental science and technology projects have entered Product testing phase, at the same time, the relevant monitoring standards are also being developed.

The purpose of MEP to promote the development and application of PM2.5 monitoring equipment is to develop and industrialize PM2.5 complete sets of monitors and make relevant indicators and technical specifications.
According to the data released by the Ministry of Environmental Protection on December 28, 2012, there are currently 74 cities in China and 496 monitoring stations for the ambient air monitoring network are completed. As of January 1, 2013, these cities are beginning to release PM2.5 monitoring information.
However, insiders said that at present, most of the installation situations are based on their own monitoring requirements, the sampling standards, procurement, installation, commissioning, data collection and control of quality standards are not uniform, the control conditions are not expressly binding. "The country needs a set of quality control standards to ensure that equipment data is accurate." An industry expert said.
"Generally speaking, the equipment is subject to a one-year comparison test to determine the appropriate test parameters for the local operation, and it even takes two to three years abroad." Du Xinping, head of the Environmental Protection Marketing Department, said.
"Since October 2012, China National Environmental Monitoring Station has selected 10 representative areas in the country for testing," Du Xinping said, in order to "make up classes." However, with the previous release of the recommended list and voluntary production of PM2.5 monitoring equipment, compared to the test, the test equipment used in all domestic. Du Xinping said the test is "a part of the national major scientific instrument and equipment development special project" development and application of "fine atmospheric particles (PM2.5) monitoring equipment."
It is understood that the purpose of advancing the above project is to develop and industrialize complete sets of PM2.5 monitor, and to develop relevant indicators and technical specifications for PM2.5 monitoring, the formation of domestic PM2.5 monitoring of the whole process of quality control system and serialization Standard analysis method and PM2.5 monitoring system. The project is based on self-developed PM2.5 continuous automatic monitor / particle size spectrometer and PM2.5 cutter / sampler based on β-ray method, oscillation balance method and light scattering method to realize continuous sampling of fine particles and its quality Concentration of real-time accurate monitoring, PM2.5 for our environmental management to provide technical support.
It is reported that this project was officially launched in Beijing on January 10, 2013. China National Environmental Monitoring Station as a technical supporter, and environmental protection as a project leader, including the monitoring stations, local monitoring centers and research institutes, Wuhan Rainbow Instrument Co., Ltd., Wuxi Branch Optoelectronics Technology Co., Ltd. and a total of 16 units involved. The total project funding is 88.88 million yuan, of which 40.88 million yuan is for special funds for the development of major national instruments and equipment.
Du Xinping said that in October 2012, precedent environmental protection products have been introduced, currently 53 points in Hebei and Ningxia 7 points to use, and has begun mass production.
Imported equipment "acclimatized"
As China's PM2.5 monitoring instrument technology research and development started late, based on the relative weakness, monitoring accuracy and stability can not be guaranteed.
This reporter learned that it is precisely because of the lack of monitoring standards around the "imported PM2.5 monitoring instruments currently account for 80% market share, both in this market operators such as Thermo Fisher and other foreign-owned enterprises, there are Chinese enterprises introducing foreign products such as Dongjiang Environmental Protection. " Investment adviser in the environmental protection industry researcher Pan Yuhong said.
On different occasions, Zhou Xiaobin, director of environmental instruments business of Thermo Fisher Scientific, researcher of Institute of Atmospheric Physics of Chinese Academy of Sciences, and Wang Yue-si, director of CERN atmospheric science center all give such data. According to Du Xinping estimates that this figure may reach 85%.
"The intensive monitoring of PM2.5 is a particularly fast process, and the purchase of equipment is fast all over the world, with imports mostly being imported by October 2012." Du Xinping said.
Zhou Xiaobin also said explosive growth in equipment sales began in the second quarter of 2012 and continued into the fourth quarter. "According to our statistics, the installed capacity in China in 2012 is about 1,000 units."
"Since the research and development of PM2.5 monitoring equipment in our country started relatively late, the basis is relatively weak, and the accuracy and stability of monitoring can not be guaranteed. Currently, many pilot areas generally choose better-quality imported products when purchasing." Pan Yuhong Analysis .
However, the import equipment "acclimatized" phenomenon is quite worrying. PM2.5 Automatic Monitoring Instrument Technical Indicators and Requirements (Provisional) issued by China National Environmental Monitoring Station in May 2012 identified three kinds of automatic monitoring methods for PM2.5, which were the installation of dynamic heating system by β-ray method, β-ray method instrument plus dynamic heating system combined with light scattering method, micro oscillating balance method instrument plus film dynamic measurement system (FDMS).
Wang Yue Si pointed out that in the use of FDMS micro oscillation method, the humid environment in southern or polluted cities too much environmental conditions lead to FDMS can not be used normally. "Many cities have high concentrations of fine particles. Excessive fine particles cause the micropores of the FDMS permeable membrane to be quickly clogged with fine particles, reducing their useful life to half that of foreign countries, which may change in 2-3 months Once, the cost of a permeable membrane is about $ 1,000, which is not a small cost to many monitoring stations.
