Overview
There are various types of indoor air pollutants in office spaces, including physical pollution, chemical pollution, biological pollution, and radioactive pollution. The sources of pollutants that cause indoor and outdoor air pollution are roughly divided into the following categories: firstly, particulate matter such as dust, ash, and smoke, which generally come from smoking, cooking with firewood in rural areas, and secondary dust from construction sites.
Product Details
Indoor air quality testing in office spacesThe institution is a technical process for analyzing and testing indoor air pollutants caused by interior decoration and furniture purchases, and issuing testing reports based on the test results.
Due to the wide range and variety of indoor air pollutants, various pollutants have different degrees of harm to the human body. In modern building design, the effective use of energy is increasingly considered, resulting in very little ventilation between indoor and outdoor environments. In this case, indoor and outdoor environments become two relatively different environments. Therefore, indoor air pollution has its own characteristics, mainly manifested in the following aspects:
Many indoor air pollutants can cause great harm to the human body in the short term, and some have a long incubation period. Usually, the time is between 3-15 years. For example, radioactive pollution has a latent period of several decades.
Indoor environment is the main place where people live and work. At least half of a person's life is spent indoors, and prolonged exposure to polluted indoor air environments exacerbates the cumulative harm of pollutants to the human body.
Indoor air quality testing in office spacesThere are various types of indoor air pollutants, including physical pollution, chemical pollution, biological pollution, radioactive pollution, etc. The sources of pollutants that cause indoor and outdoor air pollution are roughly divided into the following categories: firstly, particulate matter such as dust, ash, and smoke, which generally come from smoking, cooking with firewood in rural areas, and secondary dust from construction sites. The second is chemical pollutants such as sulfur dioxide and nitrogen dioxide. These harmful chemical pollutants in the air mainly come from the smoke and dust released from coal combustion and the exhaust emissions from cars. These harmful gases will enter indoors through doors and windows. The third is microbial pollutants.
Testing standard: GB/T18883-2022 "Indoor Air Quality Standards"
