Zhang Yinping, director of Tsinghua University Building Environment Testing Center, pointed out in the article that high concentration of formaldehyde will combine with protein, which will seriously stimulate the respiratory tract, thus causing a series of symptoms such as edema and headache. In addition, long-term exposure to low-concentration formaldehyde may also cause chronic respiratory diseases, leading to menstrual disorders in women, chromosomal abnormalities in newborns, and even nasopharyngeal carcinoma.
People's Daily published an article "How to prevent indoor formaldehyde pollution in formaldehyde release 15 years? It is pointed out that formaldehyde volatilizes for a long time, and the release time of formaldehyde contained in decoration materials such as wood-based panels is about 3~ 15 years. It is unrealistic to expect formaldehyde to evaporate after a few months of ventilation.
Extended data
1, keep ventilation, ventilation is the best way to remove formaldehyde, we must pay attention to ventilation after the renovation of the new house, and it is best to dry the newly renovated house for a few months before moving in.
2. Buy products with guaranteed quality: formaldehyde residues often exist at home. If conditions permit, buying furniture of big brands can also be relatively guaranteed. In addition, try to use environmentally friendly home improvement materials when decorating.
3. in addition to formaldehyde with activated carbon and plants: Activated carbon adsorption and plants also play a certain in addition to formaldehyde role. The structural characteristics of activated carbon are many pores and strong adsorption. It is best to choose activated carbon with relatively small particles. The smaller the particles, the better the adsorption effect. Generally, newly renovated rooms use activated carbon, and the dosage is per square meter 1 bag (50g).
