What gases do you need to detect for air quality testing Can

The quality of indoor air determines the quality of the environment in which we work, live and live indoors. What are the gases that need to be detected in indoor air? Gas detector and how to use it?
 
Among the items of indoor air quality testing, six items such as formaldehyde, triphenylene, ammonia, ozone, radon and TVOC are generally required. The values of these six items will not bring harm to human health only if they are below a certain level.
 
If the concentration of gases in the air exceeds the standard, it does not meet the requirements of the environment where people live or work, and if they are in this environment for a long time, it will have long-term adverse effects on human body.
 
For example, the hazards of formaldehyde.
 
Formaldehyde is a highly irritating gas, colorless and easily soluble in water. Formaldehyde exists in many types of objects, such as decoration often used in the density board, plywood and particle board and other artificial panels. In addition, wallpaper and adhesives and other places are also the main source of formaldehyde production. In general, the time cycle of formaldehyde release from these items is as long as 3 to 5 years.
 
People in this environment inhale indoor formaldehyde through the respiratory tract and are absorbed by the body, thus posing a health hazard. The health hazard of formaldehyde to our body is long-lasting, and there are hidden and latent characteristics, if the human body inhales excessive formaldehyde for a long time, it is easy to cause very serious diseases such as throat cancer or nasopharyngeal cancer, so formaldehyde is a very important item in air quality testing.
 
 
The hazards of triphenylene.
 
Triphenylbenzene mainly has three types of benzene, toluene and xylene, which can be used as solvents or chemical raw materials. Triphenylene is a colorless gas, they have a special aromatic odor, often found in paints, coatings, glues and adhesives, these items released in the benzene material is also the main source of benzene, toluene, xylene in the air. If the human body inhales benzene for a long time, it will lead to anesthesia symptoms in the central nervous system, and also inhibit the hematopoietic function of the human body, resulting in a significant decrease in white blood cells, platelets and red blood cells, increasing the probability of aplastic anemia. For women, it can lead to abnormal menstruation, and if a pregnant woman is in an environment with excessive benzene for a long time, it is also easy for the fetus to develop congenital defects.
 
Hazards of ozone.
 
Ozone is a trace reactive gas that, at room temperature, appears light blue and emits a special odor. Ozone is a secondary pollutant formed by the action of sunlight, and is produced through chemical reactions. Ozone is generally used to disinfect water resources and some foods, but if the concentration of ozone in the living environment exceeds the standard, it can affect our normal life. The strong oxidation of ozone leads to various inflammatory diseases in people's body after inhalation, and the lungs are very easily damaged in a long-term ozone polluted environment, and in serious cases, ozone may even lead to human death. Ozone is commonly found in various paints and fuels in the indoor decoration environment, while the exhaust from cars also contains ozone components.
 
Hazards of radon.
 
Radon is a kind of radioactive substance and radon pollution belongs to a kind of heavy metal pollution, which can lead to the appearance of air pollution and also trigger radiation pollution. After the completion of interior decoration, indoor radon concentration can be effectively reduced by ventilating and ventilating the room. If possible, an air purifier can be used indoors to purify the room after the decoration is completed, so as to effectively reduce the indoor radon content.
 
TVOC organic compounds
 
Except formaldehyde, triphenylene, ammonia, ozone and radon, the volatile organic compounds harmful to human body in the air are collectively called TVOC, such as n-hexane and cyclohexane. In TVOC testing in China, it is generally mainly to test the content of alkanes and other substances.
 
 
How to effectively detect these harmful gases?
 
Detection of these harmful gases, you need to use to toxic and hazardous gas detector.
 
Toxic and harmful gas detectors are fixed and portable.
 
For office, living and other places of harmful gas detection, you can use portable gas detection equipment.

Portable gas detector body is small, easy to carry, open with the use of real-time detection of harmful gases in the air concentration values, if the gas concentration to be measured exceeds the standard, will issue a sound, light, vibration triple alarm signal.
