Would you like to ask if the newly opened express hotel is suitable for staying? Is formaldehyde environmentally safe?

Staying in the new hotel for one night is harmful to human health. Indoor air pollution is 5 ~ 10 times higher than outdoor air pollution, and there are more than 500 kinds of pollutants. Indoor air pollution has become the cause of many diseases, and formaldehyde is a major aspect of indoor air pollution.

First, the health hazards of formaldehyde mainly include the following aspects:

1. irritation: the main harm of formaldehyde is the irritation to skin and mucosa. Formaldehyde is a toxic substance in protoplasm, which can combine with protein. When inhaled in high concentration, severe respiratory irritation and edema, eye irritation and headache may occur.

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

3. 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.

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

Second, the risk characteristics

Its steam and air form an explosive mixture, which will cause combustion and explosion when exposed to open fire and high heat energy. In case of high heat, the internal pressure of the container rises, which is in danger of rupture and explosion. Combustion (decomposition) products: carbon monoxide and carbon dioxide.

Formaldehyde removal method

1. Ventilation in addition to formaldehyde: Ventilation in addition to formaldehyde only removes formaldehyde from indoor air. Once the doors and windows are closed, the formaldehyde hidden in the floor and cabinets will evaporate into the air!

2, green plants absorb formaldehyde: green plants such as green radish, chlorophytum and so on. Just absorb the formaldehyde around you, and formaldehyde itself will cause harm to plant cells. Green plants absorb little formaldehyde, which is not recommended!

3. Activated carbon adsorption: Activated carbon uses its high specific surface area to adsorb formaldehyde, but with the saturation of adsorption and the increase of temperature and wind speed, the adsorbed formaldehyde molecules will be released into the air again, causing secondary pollution, which is not worth the loss!

4. in addition to formaldehyde Company: Photocatalyst is used in aldehyde removal company. The first condition for the reaction between photocatalyst and formaldehyde molecules in the air is sufficient illumination; Secondly, once the film formed by photocatalyst on the surface of decoration materials and furniture falls off, formaldehyde molecules will volatilize into the air, causing pollution.
