When it comes to indoor air pollution, formaldehyde is the first thing people think of. Many people's understanding of formaldehyde is biased. They regard formaldehyde as a monster, and it will hurt if it is touched. But real formaldehyde is not.
Formaldehyde is everywhere in our living environment. Human beings have been coexisting with trace amounts of formaldehyde. Plants themselves produce formaldehyde. However, trace formaldehyde has no effect on health.
Under normal circumstances, ordinary people to absorb formaldehyde poisoning, may be drinking fake wine, fake wine in the body into formaldehyde poisoning.
Formaldehyde does have the possibility of inducing cancer and leukemia, but this is mainly in the aspect of occupational diseases. Long term exposure to formaldehyde in the environment can cause such diseases. Trace formaldehyde in daily life is not enough to cause disease. And in addition to due to professional reasons, new house decoration can also let the general public stay in the formaldehyde environment for a long time, which is a place that many people are easy to ignore.
The following five points, firmly remember, we have a thorough understanding of formaldehyde.
1. Can formaldehyde appear only in interior decoration?
Not only interior decoration, but also textile products such as wood furniture, glue, paint and clothes are the sources of indoor formaldehyde emission. The molecular weight of formaldehyde is similar to that of ordinary air, even slightly heavier, so it is generally below one meter in height. Children and pets are the most vulnerable.
2. Is there no formaldehyde half a year after decoration?
The release time of formaldehyde is as long as 3-15 years, which is not a problem that can be solved by ventilation for half a year. In addition, the release of formaldehyde is also affected by temperature and humidity. The higher the temperature and the higher the humidity, the faster the formaldehyde volatilization. In short, the release peak of formaldehyde is in spring and summer, and less in autumn and winter. In addition to formaldehyde, the best choice is spring and summer.
3. Is there no formaldehyde in the house?
Generally speaking, you can't smell formaldehyde. Human olfactory can smell formaldehyde, formaldehyde exceed the standard is generally more than three times. So don't use your nose to judge whether formaldehyde exceeds the standard at home.
4. Is formaldehyde tester useful?
Although the formaldehyde tester is selling well, it is recommended to find a professional testing agency to do the indoor formaldehyde test. More than ten yuan of formaldehyde detector and national professional certification of laboratory testing, of course, the latter is more professional. Ten to hundreds of yuan, even a reliable detection components can not be bought, such a formaldehyde tester is IQ tax.
5. Can plants remove formaldehyde?
Although there are many biological methods for formaldehyde removal, the efficiency is too low and there is no practicability. Formaldehyde concentration exceeds the tolerance range of plants, but also can easily kill plants, let go of poor potted plants! Like Chlorophytum known as a good hand in formaldehyde removal, if you want to use it to remove formaldehyde, you need to cultivate a Chlorophytum forest at home.
If there are old people, pregnant women and infants in the family, we should pay special attention to the formaldehyde problem in the house. After all, the fragile respiratory system of the elderly and infants and the reproductive system of pregnant women may be damaged by formaldehyde.
