Which decoration materials are harmful to human body!

In short, formaldehyde and benzene. . As long as there are basically wood core boards and fiberboard density boards containing these substances. . Less harmful ones, such as knuckles, preferably E0-grade coatings, are basically available. Don't think that all selected or well-known brands will have no decoration pollution. After manual treatment, the materials are more or less harmful to human body, so the decoration style must be natural and not too complicated. But if you must use a lot of materials for aesthetic reasons, you must move in after half a year of natural ventilation. According to indoor air quality standards, you can move in after seven days or a month, which is actually not feasible. In the complaint cases I have tested, I usually live in it after one month, but the formaldehyde or toluene still exceeds the standard. For special people, we must pay attention to this. In the past, benzene and formaldehyde easily exceeded the standard. But now, according to my personal work practice, it is toluene, formaldehyde and TVOC. Toluene generally comes from paint. Benzene was used as solvent in the past, but it was too harmful. So now toluene or xylene is generally used as diluent, which volatilizes quickly and does little harm. So try to choose famous brands, your point is worthwhile, quality is guaranteed, and health is the most important. Formaldehyde mainly comes from the joinery board for decoration, and all the furniture made on site should be used. It is best to choose E0 indoor or E 1 outdoor. When making furniture, the pressing panel needs glue, which contains formaldehyde, so the glue should also choose famous brands. Note that the emission period of formaldehyde is 10 to 15, and it will not be completely volatilized for a while. It is worthwhile to spend more money to use the board. Total volatile organic compounds are also easy to exceed the standard. The last time I went to the newspaper office for inspection, it was the reception room. The plastic cover outside the newly bought sofa has not been taken off. The field measurement with instruments is 0.4, and the upper limit of the standard is 0.6. It can be seen that this indicator is quite easy to surpass. Third, the others, that is, the radiation of stone and radon in floor tiles, are actually of higher nature, so it is ok to decorate marble without too much. For floor tiles, they are all made by big factories with high quality and reliability. Fourth, after the installation, do the test, don't look for some unqualified institutions in the society, and shake the portable instrument twice to get the results. Be sure to go to a formal institution and produce a legally binding report. The cover of the test report is marked with CMC and CAL. In the future, if there are any consequences caused by decoration, at least a formal appraisal report can be used as evidence. Generally speaking, except radioactive substances and TVOC are measured on site, others are measured by high-precision gas chromatograph and other instruments after collecting air samples on site.
