What are the indoor air quality monitoring standards?
With the further improvement of living standards and science and technology, people have become more and more aware of the close relationship between indoor air quality and people's health, and pay more attention to indoor air quality. In the Air Purification Conference held on November 28, 2020, Zhong Nanshan stated: 'People spend 80% of their time indoors in their daily life, work, study, and other aspects. The air he is exposed to is also mainly It is indoor air; a person has to breathe more than 20,000 times a day and exchange at least 10,000 liters of gas with the environment every day. It can be seen that if indoor air is polluted, it will cause great harm to human health.' Currently, there are five main hazards and indicators of indoor pollutants.Radon gas: exists in the cement, ballast bricks and decorative stones of buildings. After the national national standard for radon content was promulgated, the standard for newly built houses is less than 100 Bq/m3, and the standard for newly built houses is less than 200 Bq/m3. The main hazard of radon to humans is lung cancer, which is the second leading cause of lung cancer besides smoking. Formaldehyde: Formaldehyde mainly comes from man-made panels and is confirmed as a suspicious carcinogen by the WHO, which mainly affects the respiratory system. The 'Hygienic Standard for Formaldehyde in Indoor Air' promulgated by the former State Bureau of Technical Supervision and the Ministry of Health in 1995 stipulated that the maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/m3. The indoor standard set by the Ministry of Health and Construction is still 0.08 mg/m3. But for public buildings and other buildings, 0.12 mg/m3 is required. Ammonia: Indoor ammonia mainly comes from concrete antifreeze. The main hazards of ammonia to the human body are irritation and damage to the respiratory tract, eye mucosa and skin. According to the 2001 Indoor Environmental Pollution Control Standard for Civil Construction Engineering, the concentration of ammonia nitrogen in indoor air is below 0.2 mg per cubic meter. Benzene: Paints, adhesives and various interior wall coatings contain benzene, toluene and xylene. The World Health Organization believes that benzene is a carcinogen, which can easily cause damage to the human body's hematopoietic function. The standard established by the National Health and Family Planning Commission stipulates that the standard for indoor air benzene series is less than 0.09 mg per cubic meter. All volatile organic compounds (TVOC) in the atmosphere: Broadly speaking, any organic compound that naturally volatilizes from liquid or solid indoors at room temperature and pressure belongs to the category of TVOC, and TVOC is a heterogeneous pollution in indoor air. Objects are extremely complex, and new types are constantly being synthesized. In addition to aldehydes, benzene, toluene, xylene, trichloroethylene, chloroform, naphthalene, diisocyanate, etc. are common in TVOC. These substances mainly come from various coatings, adhesives and various man-made materials. According to the requirements of my country's 'Code for Indoor Environmental Pollution Control of Civil Construction EngineeringIn order to facilitate the understanding of indoor air quality, more and more people use indoor air quality sensors to monitor different gas concentrations in the air to protect people's health. With the advancement of intelligent construction, it seems that the problem of indoor air quality control is not just a 'pure detection' project. At present, there are a wide variety of air detection equipment on the market, with specialized instruments such as PM2.5 sensors, nitrogen oxide analyzers, formaldehyde detectors, etc., as well as air quality sensors that integrate all air quality elements. Satisfy multiple market needs such as testing, monitoring, and monitoring. 1. The accuracy and performance requirements of the monitoring instrument are higher, and it can quickly and accurately detect the content of the main pollutants in the indoor air;2, it has an automated, intelligent, networked interactive page and data management capabilities , Analytical ability, stronger decision-making; 3. The indoor air purification efficiency is higher, and at the same time, it should also have innovative points such as power consumption monitoring, convenience and efficiency, and intelligent linkage.
These sensor solution environmental monitoring systems are meant to serve as a guide for business owners on how to both identify potential opportunities for transformative innovation and how to adapt to the constantly changing technologies of today.
