If it's not too harsh, it's ok. Don't be misled by the excessive publicity of the media. Now almost all home improvement materials and furniture contain formaldehyde to some extent. Of course it's not the best, but it's impossible. We can only ask not to exceed the standard too much.

The following is an excerpt:

A. irritation: the main harm of formaldehyde is irritation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. Inhalation of high concentration will cause severe irritation and edema of respiratory tract, eye irritation and headache.

B sensitization: direct contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.

C. Mutagenesis: High concentration of formaldehyde is still a genotoxic substance. Experimental animals can cause nasopharyngeal tumors under the condition of high concentration inhalation in laboratory.

D outstanding manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, loss of appetite, palpitation, insomnia, weight loss, memory loss, autonomic nervous disorder; Long-term inhalation by pregnant women may lead to fetal malformation or even death, while long-term inhalation by men may lead to male sperm malformation and death.

Note: Generally, formaldehyde in newly renovated houses will exceed the standard. As long as one or two pots of chlorophytum are put in the new house, formaldehyde will be partially absorbed. However, because the volatilization time of formaldehyde is as long as 3- 15 years, it is impossible to remove formaldehyde solely by plants. If necessary, professional air handling institutions or products can be considered.
