According to the summary of authoritative in addition to formaldehyde Company, the impact of indoor environmental quality on human health can be divided into two categories, namely, bad building syndrome and building-related diseases.
First of all, uncompleted residential flats syndrome (SBS) originated in 1970s and was put forward by some developed countries abroad. Because of the air pollution in some buildings and the low exchange rate of indoor fresh air, people living in buildings will have a series of nonspecific symptoms, such as ear, nose and throat irritation, headache, dizziness, fatigue, dyspnea and skin allergy. These symptoms can be obviously relieved after leaving the building. Because most of these symptoms are related to air pollution in buildings, the World Health Organization explained this phenomenon for the first time in 1982, calling it bad building syndrome.
Second, the term BRI is similar to bad building syndrome at first, but the same concept has different expressions in different documents. In 199 1, the joint action organization of indoor air quality and its health impact in Europe is redefined. After that, it refers to respiratory infection, cardiovascular disease, cancer and other related diseases with consistent clinical manifestations caused by poor indoor air quality due to specific factors such as improper site selection, design and decoration materials, which will not improve even if they leave the environment that causes building-related diseases. This is the so-called building-related disease.
Finally, both bad building syndrome and building-related diseases are related to indoor air pollution. We can effectively reduce the occurrence of such symptoms by improving the living environment and improving the indoor air quality. For example, increasing indoor ventilation per unit time or finding a professional in addition to formaldehyde company for indoor air control and other effective ways.
