Background
With the advancement of science and technology and the rapid development of the national economy. After the rise of the industrialization era, and chemical companies and other companies have risen. The rise of chemical companies has brought benefits to people at the same time.
Various plants and organisms in the water are busy, and the overall water quality is seriously polluted. The source of all this is the air pollution caused by the gas discharged by the chemical industry and other enterprises.
At the same time, people’s respiratory diseases occur. The probability of getting worse is increasing, and the harmful gases and suspended particles in the air increase. Causing serious damage and threat to people’s respiratory system. It is precisely because of various hazards and threats that it is very important to monitor the atmosphere and the air environment.
What is Particulate matter
Particulate matter in the air is generally have two categories. Namely PM10 and fine particulate matter PM2.5. Both categories are air pollutants that are more harmful to the human body. The former means that the particle size is 10 microns. For the following particulate matter, the latter refers to particulate matter with a particle size of 2.5 microns or less.
Various industrial processes can produce PM10. In addition, in nature, some ultra fine particles and bacteria will stick together to form aerosols, which is also one of the sources of PM10 in the air.
PM2.5 includes natural products such as soil dust, sea salt, pollen, spores, bacteria, and volcanic ash, as well as smoke and dust generated in industrial projects such as power generation, metallurgy, oil refining, chemistry, and textiles, and droplets left due to insufficient fuel combustion. in the Indoor rooms, second-hand smoke and hot oil cooking will also form a large number of PM2.5 particles.
Some of these substances can cause discomfort, such as cough, asthma, rhinitis and other respiratory diseases; Others can cause damage to the heart, liver and stomach. In addition to the above easily observed phenomena, long-term exposure to high LEVELS of PM10 and PM2.5 also increases the risk of lung cancer.
In addition, if the air contains higher concentrations of PM10 and PM2.5, it will also reduce the visibility of the atmosphere, and the whole sky will look gray. Buildings in the area are also more vulnerable to erosion. Those modern buildings with reinforced concrete structures or large glass facades are less affected because of their strong anti-corrosion ability, but those ancient and historical buildings, especially wooden structures, may cause the collapse of the house
The effect of Particulate matter
Otherwise, the erosion effect of PM10 and PM2.5 on these buildings is not worse than that of acid rain. The erosion process is more permanent and pervasive. Acid rain will only damage the roof and exterior walls of the building.
PM10 will also accumulate in the human respiratory system. Causing various diseases and causing great harm.The particles of PM2.5 are smaller, so under the same mass, the surface area is larger, the activity is stronger, and toxic and harmful substances are more likely to be attached. The residence time in the atmosphere is longer than that of PM10, and the diffusion range is farther, so PM2 .5 is more harmful than PM10.
The importance of air quality monitoring system
Theair quality monitoring system can continuously and automatically monitor the real-time changes of ambient air gaseous pollutants (SO2, NO2, CO.03) and ambient air particulate matter (PM2.5, PM10) around the clock, and quickly and accurately collect and process monitoring data. Realize the online automatic monitoring of regional air quality. Atmospheric grid monitoring system is widely used in urban environment monitoring, residential air quality, park forest environment, enterprise chemical park and other scenes.
The air quality monitoring cloud platform mainly realizes the display and management of atmospheric information monitoring data. Through the collection/filtering/fusion summary/analysis of information. In order to grasp the dynamic information of the atmospheric environment, scientifically formulate solutions and realize disaster warning.
Summarize
More and more counties are paying attention to air quality monitoring. Because air quality monitoring is very important whether it is in the management of road dust. Nitrogen oxides or the protection of the human respiratory system. In order to better protect the environment and health, whether for industrial and agricultural practitioners or environmental protection agencies. The atmospheric monitoring system can provide you with protection.
