What are the hazards of formaldehyde and how to remove it?

We all know that formaldehyde is a toxic gas that has a great impact on human skin and mucous membranes. Once the indoor formaldehyde concentration exceeds the standard, a series of poisoning symptoms will appear. So what are its hazards? How to clear it?

The health hazards of formaldehyde are mainly in the following aspects:

a. Irritation: The main hazard of formaldehyde is irritation to the skin and mucous membranes. Formaldehyde is a protoplasmic toxic substance that can bind to proteins. When inhaled in high concentrations, it can cause severe respiratory irritation and edema, eye irritation, and headaches.

b. Sensitization: Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation, and necrosis. Inhalation of high concentrations of formaldehyde can induce bronchial asthma.

c. Mutagenic effect: High concentration of formaldehyde is also a genotoxic substance. Experimental animals may develop nasopharyngeal tumors if they inhale high concentrations in the laboratory.

d. Outstanding symptoms: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss, memory loss and autonomic nervous system disorder, etc. Long-term inhalation by pregnant women may cause fetal malformation or even death, and long-term inhalation by men may cause sperm malformation and death, etc.
