It can be seen how serious the harm of formaldehyde is. In the process of home improvement, we only know the presence of formaldehyde, but we do not know whether or not formaldehyde will be emitted from home building materials. During the period of 3-15 years, formaldehyde was continuously released.
Today, the author gave everyone a detailed introduction, in the home improvement, which home improvement building materials will release formaldehyde, home improvement friends do enough homework.
Composite flooring, solid wood flooring, floor leather, wallpaper, solid wood panels, MDF, gypsum carvings, ceramic tiles, primers, finishes, decorative coatings, decorative adhesives, etc. are all sources of formaldehyde hazards after home improvement.
The harm of formaldehyde to health mainly includes the following aspects:
a, irritant effects: The main hazards of formaldehyde are manifested as irritative effects on the skin and mucous membranes. Formaldehyde is a venomous substance that binds to proteins and causes severe respiratory irritations, edema, eye irritation, and headaches when inhaled at high concentrations.
b, sensitization: direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, necrosis, inhalation of high concentrations of formaldehyde can induce bronchial asthma.
c. Mutagenicity: High concentration of formaldehyde is also a genotoxic substance. Laboratory animals can cause nasopharyngeal tumors when inhaled in high concentrations in the laboratory.
d, outstanding performance: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, appetite, heart palpitations, insomnia, weight loss, hypotension and autonomic disorders; long-term inhalation of pregnant women may lead to fetal malformations , Even death, men long-term inhalation can lead to male sperm deformity, death and so on.
Note: The formaldehyde in the newly renovated house will exceed the standard. As long as one or two pots of spider plants are placed in the new house, formaldehyde will be partially absorbed. However, because the volatilization time of formaldehyde is as long as 3-15 years, the plant is used to remove formaldehyde. It is not enough. The best way is ventilation and correct formaldehyde treatment.
