The numerous sites make environmental pollution invisible

in recent years, the problem of global warming has become increasingly serious, and PM2.5 is one of the more serious pollution sources among many pollution sources. As the largest developing country, China has undertaken the due and obligations of a big country. In recent years, the Ministry of environmental protection of the people's Republic of China and local environmental departments have successively issued various environmental protection policies to further strengthen the remediation of environmental problems and restore the blue sky and clear water to the people

at the same time, with the support of policies, a large number of PM2.5 environmental monitoring stations have been added in various places to further strengthen the monitoring of pollutants and the investigation of pollution sources, so as to carry out targeted environmental treatment

pm2.5 data direct transmission monitoring master station platform

it is learned from China environmental monitoring master station that at present, China has set up more than 5000 monitoring stations at the national, provincial, municipal and county levels, and ambient air quality monitoring has been completed. Since the 12th Five Year Plan, China has initially formed a technical system to meet the needs of routine monitoring of atmospheric environment, and has developed monitoring technologies such as PM2.5, ozone and volatile organic compounds VOCs

according to the experts, in order to ensure the authenticity and effectiveness of the monitoring data, after the monitoring data is generated at each state-controlled station, the original data are directly transmitted to the urban station, provincial station and China environmental monitoring station platform at the first time, and the monitoring data of the station are obtained at the three levels at the same time. 1436 state-controlled monitoring stations have established remote quality control systems, which have the functions of change trace and abnormal alarm

the Ministry of environmental protection launched the construction of components in november2016. At present, more than 70 super sites have been built. In order to strengthen the response to the heavily polluted weather in Beijing, Tianjin, Hebei and surrounding areas, and carry out the analysis of the causes of air pollution and the evaluation of the effect of emergency measures, the components currently established cover 20 cities such as Beijing, Tianjin, Shijiazhuang, Zhengzhou and Jinan

pm2.5 Monitoring covers more intensive monitoring stations in Beijing, Tianjin and Hebei. Since the "12th Five Year Plan", China has made important breakthroughs in individual technologies for atmospheric environment monitoring, initially formed a technical system to meet the needs of routine monitoring business, developed PM2.5, ozone, volatile organic compounds VOCs and other monitoring technologies, and effectively supported the implementation of China's new air quality standards during the "12th Five Year Plan"

among them, Ping'an equipment should work immediately. High end scientific research instruments such as single particle aerosol time of flight mass spectrometer have been applied, and the sensitivity of spectral quantitative detection has reached the international advanced level; Breakthroughs have been made in key technologies such as remote measurement of VOCs from pollution non-point sources, vertical detection of atmospheric composition, particulate matter and ozone; It realizes remote sensing monitoring of the distribution of sulfur dioxide, nitrogen dioxide and other polluting gases and aerosol particles on the aviation platform

it is reported that in terms of the setting of atmospheric science and technology projects, in 2017, China will continue to carry out research on the measurement technology of atmospheric free radicals and chemical components of nano particles, the key atmospheric processes that affect the regional emission and sedimentation response, and in terms of the whole process control technology of pollution sources, carry out research, development and application demonstration of multi pollutant collaborative control technology in coal-fired power stations, metallurgy and building materials industries, and civil coal-fired pollution control technology

air quality monitoring stations in Chengdu, Sichuan are set up according to national specifications and operated by a third party.

Chengdu, Sichuan has a total of 8 state-controlled air monitoring sub stations uniformly planned and set by the state. According to the requirements of the Ministry of environmental protection, since January, 2013, Chengdu state-controlled air monitoring sub station has officially started monitoring six items according to the new standard, including sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, inhalable particulate matter (PM10) and fine particulate matter (PM2.5)

the automatic monitoring instrument in the substation operates continuously throughout the year, and the data is updated every hour. AQI presents these six pollutants with unified evaluation standards. In order to ensure the authenticity and authority of the monitoring data, once the point is set, the environmental protection department will entrust the third-party operation and maintenance management, and no one else can approach it

automatic monitoring instruments can accurately, timely and comprehensively reflect the current situation and development trend of environmental quality, and provide scientific basis for environmental management, pollution source control, environmental planning, etc. In order to ensure the quality of instruments and the accuracy of monitoring data that plastic waste will be blocked by the vertical floating grid of suspenders, Chengdu adopts advanced equipment, which provides effective equipment support for environmental governance

establishment and operation of the first PM2.5 atmospheric composition monitoring station in Tianmen City, Hubei Province

in order to further improve the meteorological monitoring, forecasting and early warning services of air pollution, the Meteorological Bureau of Tianmen City, Hubei Province has improved the monitoring system and built the first PM2.5 atmospheric composition monitoring station in the city, which serves the sulfur dioxide, nitrogen oxides and inhalable companies in food and health products, personal care, feed, medical equipment, automobiles, coatings and paints, electronics and electrical The indicators of major pollutants such as life protection particles, fine particles, ozone and carbon monoxide shall be monitored continuously and automatically for 24 hours. According to the data analyzed in the detection station, the air quality level is evaluated in detail, and the environment is treated according to the evaluation results. At the same time, the Municipal Meteorological Bureau has also established and improved the linkage mechanism with the environmental protection department, strengthened cooperation in air monitoring, forecasting and early warning, carried out comprehensive environmental monitoring, held joint consultations in case of heavy pollution weather, and jointly issued pollution weather early warning forecasts

set up PM2.5 automatic monitoring station Shaoxing will cover water and gas monitoring this year as the first batch of pilot units for big data construction of ecological environment in China. Last year, Shaoxing durometer was in the normal operation mechanism state, and then the samples were formally tested to explore the implementation of township environmental protection, and the city's water and gas monitoring network was greatly integrated and re distributed. In terms of water environment, Shaoxing City has integrated 85 surface water assessment sections of the environmental protection department with 78 water function area sections of the water conservancy department, and 128 assessment sections have been integrated. In terms of atmospheric environment, Shaoxing has built 49 key township (street) PM2.5 monitoring stations on the basis of 21 township (street) air monitoring stations; On the basis of the existing 6 automatic air monitoring stations in key development areas, 8 new stations will be built

this year, Shaoxing will further improve the monitoring network. On the basis of 25 automatic water quality monitoring stations, Shaoxing plans to build another 103 micro automatic monitoring stations this year to achieve full coverage of automatic water quality monitoring. At the same time, another 41 Township PM2.5 automatic monitoring stations will be built to achieve full coverage of township (street) monitoring points in the city

pm2.5 has appeared more and more in people's vision in recent years, not only because the environmental pollution problem has affected people's health in a large scale, but also because the national supervision in this field is becoming more and more strict. The emergence of more and more monitoring stations is also a wake-up call for people to pay more attention to environmental pollution. It also indicates that China has made more and more investment in the field of environment and has a stronger awareness of environmental protection
