"Haze" come, dont be afraid of monitoring instrument for you to prop up the sky

The treacherous enemy haze

　　Haze refers to the pollutant source emission (various gases and particles such as CO, SO2, NOx, NH3, VOCs, PM), in particular under the condition of atmospheric flow, through a series of physical and chemical processes, fine particle formation, atmospheric extinction phenomenon and result in interaction with water vapor. Because of the complexity of the emission of pollutants, leading to haze composition is also very complicated. Among them, the most familiar to the net friend is PM2.5. As a small particle that encompasses all the elements of the periodic table, PM2.5 also involves more than thirty thousand organic and inorganic compounds. From this point can be seen, although PM2.5 "small", but the heart has installed a whole "big world"".

　　But if you think haze equals PM2.5, you're wrong. It is understood that the composition of haze can be based on ambient air equivalent diameter of aerodynamics roughly divided into PM1-10. Among them, PM1-2.5 has the greatest impact on the human body, so it is familiar to everyone. Speaking of PM2.5-10, you may be unfamiliar, but said it has another name - sandstorm is absolutely ruleiguaner. If PM1-2.5 is a long, soft, soft attack, then PM2.5-10               is a "hard and fast" hard attack".Either way, it's a huge challenge for society.

　　Looking around the world, from 1975 to the present, in addition to Europe, countries around the world PM2.5 concentration is on the rise. Of these impressive rises, only 10% are natural emissions, and others come directly from the economic activity of human society. Beijing as an international metropolis, in addition to surrounding environmental factors and seasonal changes, the data show that coal and motor vehicle emissions is the "haze" of the "culprit."".

　　The first enemy of human health"

　　As mentioned earlier, the haze in the health of the greatest impact on non PM2.5. Because the particles are small in diameter, they can enter the human body through breathing, etc., and have a great adverse effect on human organs including the nervous system and the cardiovascular system.

　　In addition to the recognized damage to the respiratory system, according to Harvard University School of public health research shows that pollutants in the fog and haze will not only lead to myocardial infarction, but also myocardial ischemia or injury. "National Academy of Sciences magazine" is sharp pointed out that China's north and South regions of fog and haze average reduction of 5.5 years of life for the northern people, began the national haze campaign is imminent.

　　Haze prevention and control, monitoring ahead

　　When it comes to dealing with haze, environmental monitoring is a topic that can not be avoided.

　　With the rapid development of science and technology throughout the country, China is also constantly strengthening environmental protection efforts. In recent years, all provinces and cities have been scrambling to create an environment monitoring network. According to the ministry news, in the "guidance" on the promotion of environmental monitoring service socialization, the next step, the environmental protection departments will also speed up the revision of "management measures" of environmental monitoring, to further promote the "environmental monitoring regulations" promulgated.

　　As an important basis for information sources of environmental protection, environmental protection instruments take on three great tasks, such as environmental monitoring, quality evaluation and providing scientific basis for environmental governance. At present, China's vast area of 750 thousand square kilometers of haze areas, to strengthen monitoring data connectivity between countries has become a necessary means. Governance haze can not happen overnight, nor is it all around "haze", "only I alone" green". Strengthen monitoring data exchange around, master first-hand environmental information, in order to do a good job of "anti haze" preparations.

　　In front of China's vast land area, air monitoring instrument has been "unable", single handedly achieve all-round multi angle anti haze is tantamount to climbing on foot. Based on this situation, a number of instrument air quality continuous automatic monitoring of flue gas on-line system, automatic monitoring system and emergency monitoring vehicles, to create coverage of environmental monitoring network across the country, from the point of strengthening anti haze intensity, anti haze effect in order to gain immediate.

　　A series of negative effects of the rapid development of the city, has become the world's common "pain points", we enjoy the convenience of technology development, the ecological environment for the instrumentation industry has become more and more difficult questions. The instrumentation industry need to constantly improve the level of information, intelligence and automation, to meet the needs of society, to provide more accurate data for environmental monitoring, in order to have to face the difficulties and difficulties and courage when facing problems and smoothly done or easily solved.
