First, only attach importance to formaldehyde, do not attach importance to other harmful gases
The “Code for the Control of Indoor Environmental Pollution in Civil Buildings†promulgated by the State clearly specifies several toxic and hazardous gases that must be tested. They are: benzene, formaldehyde, hydrazine, ammonia, TVOC, where benzene and hydrazine are all gases that can be carcinogenic. The harm of benzene and hydrazine to the human body is the same as that of formaldehyde. In recent years, there have been reports of death caused by benzene poisoning. Therefore, after the renovation, the home must thoroughly test the above toxic and harmful gases. Pay equal attention to various harmful gases and cause indoor pollution.
Second, odor to determine whether there is pollution
Among toxic and harmful gases, some are odorous, such as benzene and aromatic; formaldehyde and ammonia are pungent. But there are also colorless and odorless, such as embarrassment. However, the complicated odors that are mixed together by various chemical substances are difficult to distinguish. Therefore, it is inaccurate to judge the pollution by smell. In other words, odors do not necessarily cause pollution, and those that are contaminated do not necessarily smell. In the renovated room, if you can smell the smell of formaldehyde or benzene, the pollution is already very serious. Sufficient to cause harm to human body. When we cannot smell it, we cannot say that pollution does not exist. The only method that can be accurately determined is detection.
Third, as long as the governance, anti-virus can be, do not detect
For the current methods of chemical treatment, environmental protection experts raised two questions: First, effectiveness; second, secondary pollution. We believe that governance must be targeted and effective. Even the pollutants in the room can't be determined. How can we manage it? In addition, from the family situation we have detected, there are also some that we have tested after treatment (chemical methods). The pollution situation is still very serious. Whether the treatment is invalid or not in place is not known, so experts recommend: After the renovation, check before you check in to ensure that we live safely and live at ease.
Fourth, first decoration, after the treatment
This is caused by lack of awareness of indoor pollution. Many families do not consider the problem of toxic and harmful gas pollution before the renovation. It is not correct to wait for renovations after such renovations. After decoration, materials containing toxic and harmful gases emit gas in the room for about three to fifteen years, which cannot be solved through one or two treatments. A very effective fast governance approach has so far not been seen. Therefore, the best solution is to put forward indoor environmental quality indicators before the renovation, and strictly control when selecting materials and materials. To ensure the interior environment after renovation.
