Types of air quality monitoring
Air is one of the basic and important material conditions for human survival, and air quality is also one of the topics that people are most concerned about. Types of air quality monitoring mainly refers to the toxic emissions that people emit during daily production, life and other activities. Harmful gases, especially waste gases emitted from chemical industries, steel plants, smelting plants, etc., usually cause serious environmental pollution and affect human health. With the continuous development of industry, our living environment has become worse and worse, and various words about air quality have appeared in our field of vision. Regarding our common Types of air quality monitoring, what aspects do we mainly detect?
1. Indoor air testing
For newly renovated houses, we need to test formaldehyde, ammonia, triphenyl, ozone, radon, total volatile organic compounds (TVOC), etc. in the room to ensure that the indoor air does not affect people’s health.
2. Ambient air detection
For the ambient air detection systems we often see on the road and in parks, it mainly detects formaldehyde, particulate matter, ozone, volatile organic compounds VOC and other gases in the air in the area, such as the haze we often hear. , PM2.5, etc. are among the ranks of inhalable particulate matter.
3. Air and exhaust gas detection in specific workplaces
For special working areas, the Types of air quality monitoring will also be different, mainly for organic compounds (benzene, toluene, xylene, non-methane total hydrocarbons, VOC, acrylonitrile, n-hexane, acetone, methyl ethyl ketone, styrene, ethyl acetate ester, butyl acetate, etc.), metals (cadmium, manganese, copper, zinc, selenium, lead, chromium, tin, sodium, mercury, nickel, etc.), particulate matter (dust, respirable particles), physical factors (illumination, fresh air volume , temperature, humidity, noise, etc.) to ensure the physical safety of workers in the work area and people living in surrounding living areas.
4. Generator exhaust gas detection
For thermal power plants, we need to detect smoke, blackness, nitrogen oxides, sulfur dioxide, etc. after combustion is completed to ensure that the smoke emitted outwards will cause major natural disasters such as greenhouse gases and acid rain in the atmosphere.
5. Canteen exhaust gas detection
Detecting the concentration of oil fumes and fire smoke (smoke, blackness, nitrogen oxides, sulfur dioxide) in canteens and restaurants, etc., on the one hand, ensures the safety of open flames in canteens and restaurants, and on the other hand, reduces the impact on surrounding commercial areas and residential areas.
Because there are many types of pollutants in exhaust gas, their physical and chemical properties are very complex, and their toxicity is also different. Therefore, we need to start from all aspects of life and protect our living environment starting from you and me!
