The pollutants in indoor air are more than formaldehyde, and testing instruments and equipment help safety
People are inseparable from oxygen all the time, and obtain oxygen by inhaling air. An adult needs to inhale air up to 5600 liters every day to obtain enough oxygen. Therefore, polluted air has a direct impact on human health. More than 90% of people's life is spent indoors, and the impact of indoor air quality on people is even more crucial. It is reported that the existence of indoor pollutants in the air is determined by its own physical and chemical properties and its formation process. There are more than 900 types of indoor air pollutants. At present, the well-known indoor air pollutants include benzene, formaldehyde, radioactive element radon and other substances. The sources of indoor air pollutants mainly include the following: Building decoration materials and indoor equipment, related pollution such as formaldehyde in phenolic resins, urea-formaldehyde resin compounds, various bacteria, fungi and spores brought by humidifiers, various volatile organic compounds in adhesives, etc.; toxic substances, including 16 kinds of volatile toxic substances in the breath substance. Radioactive pollution: that is, ionizing radiation pollution, radionuclides such as radon, thorium, and radium. Radon and its progeny penetrated by the housing base itself, as well as radioactive substances in various building materials. Biological contamination: Legionella, Actinomycetes and other bacteria, Aspergillus, Staphylococcus aureus and other fungi, germs, pollen, insect mites, etc. Naturally, the vast majority of human respiratory infectious diseases are pathogens that spread infection indoors. There are as many as 200 viruses that cause respiratory infections alone, and most of these infections are airborne indoors. It is not difficult to see that the pollutants in the indoor air can be more than formaldehyde, and the testing instruments and equipment help safety. First of all, a gas sensor is a device or device that can sense the type and concentration of a certain gas in the environment, and can convert its relevant information into electrical signals for monitoring, analysis and alarming of the gas to be measured. Furthermore, indoor air quality detectors can improve health management, and air quality monitoring parameters also play an important role in daily health management. The indoor air quality detector can include monitoring items: radon, formaldehyde, ammonia, benzene, toluene, xylene, TVOC, etc., which are in line with the definition of indoor air quality pollutants in the new version of GB50325-2020. Strengthening these air quality monitoring can help us detect pollution in time, and control air pollution through intelligent equipment such as fresh air, thereby enhancing indoor air quality in public places and reducing the risk of disease.
