[ Chinese wardrobe network ] In the life, the indoor environment of offices, rooms and restaurants, etc., has a high degree of air pollution. People spend most of their time indoors, and the quality of indoor air directly affects the health of the human body. Therefore, many people find ways to deal with the problem of indoor air pollution. In the process of governance, people often fall into the following three misunderstandings:
Misunderstanding - a low concentration of indoor pollutants is safe
In the "Indoor Air Quality Standards", China first stipulates that "indoor air should be non-toxic, harmless, and has no abnormal odor", and specifically specifies 19 indicators such as physics, chemistry, radioactivity and microorganisms, and evaluates indoor air quality. Three levels:
1. Evaluation of concentration indicators. That is, the change of indoor pollutant concentration with time is detected and evaluated.
2. Evaluation of exposure levels. It refers to the detection and evaluation of indoor and outdoor exposure to pollutants.
3. Health risk assessment. Refers to the above evaluation results and the relationship between the dose of the pollutant and the human body to assess the health hazard of a certain pollutant to indoor personnel after instant and long-term contact. That is to say, indoor air quality depends not only on the concentration of pollutants, but also on the length of time that humans are in contact with pollutants and individual differences (sensitivity).
Misunderstanding 2 is very safe to use environmentally friendly materials
In fact, after using the “green building materialsâ€, “environmental materials†and “healthy furniture†that have no pollution, the results of indoor air quality testing are often disappointing. Why is this? Originally, the so-called green building materials and environmentally friendly materials are not free of pollution, but their pollution is lower than the standards set by the state. If the amount of material used is neglected, when the amount of material used is accumulated to a certain extent, the content of toxic and harmful gases in the indoor space will exceed the standard, and it can cause harm to human health. Especially in the summer of high temperature and high humidity, the release of toxic and harmful gases in the decoration materials is very high. Therefore, the room after renovation must be thoroughly ventilated to reduce the concentration of toxic and harmful gases in the room.
Misunderstanding three renovations have pollution, and then governance will do.
The more luxurious the decoration, the more materials are used, and the more likely it is to be contaminated, and it is not realistic to think about it after renovation. Because some decoration materials release toxic and harmful gases indoors for 3 to 15 years, it can not be solved by one or two treatments, and so far there is no effective and rapid and thorough treatment. Therefore, it is best to change the concept and use comfort, safety and convenience as decoration standards to reduce unnecessary pollution.
