What harm does formaldehyde do to the human body

Formaldehyde is a chemical product that is very harmful to the body. Formaldehyde is mainly used in glue, adhesives, paints and some decoration materials. In addition, formaldehyde is also present in many daily necessities. Since formaldehyde exists in many places in our lives today, it is very bad for our health. So what harm does formaldehyde do to the human body? Let us introduce it to you in detail below.

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 combine with protein. 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. Note: The formaldehyde content in newly renovated houses usually exceeds the standard. As long as you place one or two pots of spider plants in the new house, all the formaldehyde will be absorbed. Restrictions on formaldehyde in textile printing and dyeing auxiliaries: Textile auxiliaries that make the formaldehyde content in textiles that come into direct contact with the skin exceed 30ppm and that make the formaldehyde content in all other textiles exceed 300ppm cannot be used, such as wool protectants, color fixatives, cross-linking agents, adhesives, etc. that contain excessive formaldehyde. Limit the amount of free and partially hydrolyzed formaldehyde in textile dyes to ensure that the amount of free and partially hydrolyzed formaldehyde on fabrics does not exceed 30 ppm for textiles that come into direct contact with the skin, and does not exceed 300 ppm for all other textiles. Heavy metal salts (except iron) or formaldehyde should not be used as decolorizing or fading agents in textiles.

How to remove formaldehyde at home

1. It is best not to move into a newly renovated house for the time being, because the first year after the renovation, especially the first six months, is a period of strong release of harmful gases such as formaldehyde and benzene;

2. When the indoor formaldehyde content exceeds the national standard by less than 1 times, forced ventilation can be used every day, and flowers and plants with certain formaldehyde removal ability such as spider plants can be planted to solve the problem. Another good method is to place activated carbon, but these methods act on harmful gases in indoor air, not on pollution sources, so they are suitable for situations where the content of harmful gases such as formaldehyde is small (currently, the companies that have developed well in this area are Jinwu Charcoal Sculpture, Kuaihuo Lin, and Golden Aloe);

3. When the indoor formaldehyde content exceeds the national standard by more than 1 times, it is necessary to remove formaldehyde from the source. Currently, the most effective method is to use plant herbal spray to remove formaldehyde.

The above are the harms of formaldehyde to the human body. If you can actively prevent and control it in normal times, your body will be less affected by formaldehyde. If you cannot prevent formaldehyde well, your body may develop serious symptoms of illness. In addition, you should actively take care of your body in normal times.
