Why choose an aldehyde-free floor?

What kind of substance is formaldehyde? Why do you recommend that you buy formaldehyde-free floors?

For example:

Formaldehyde, also known as formaldehyde, is an organic compound with a chemical formula of HCHO or CH2O and a molecular weight of 30.03. It is a colorless and irritating gas, which is irritating to human eyes and nose.

And what are the specific hazards of formaldehyde? There are mainly the following points:

❶Symptoms of irritation to eyes and respiratory mucosa

The main symptoms caused by long-term exposure to low concentrations of formaldehyde are tearing, sneezing, coughing and even conjunctivitis, rhinitis and bronchitis. If the concentration of formaldehyde in the air exceeds the national health standards, it will cause different degrees of harm to human health.

❷Effects on the immune system

Formaldehyde can cause allergic asthma, and can cause allergic purpura when exposed to large amounts. Compared with the people working in the unrenovated environment, the serum IgG and IgA levels of the people working in the newly decorated environment have changed, which can stimulate the production of IgG antibodies and reduce the proportion of T lymphocytes.

❸Damage to the liver

Red blood cells and liver may be the initial target organs for formaldehyde to enter the blood circulation. Formaldehyde is mainly metabolized by the liver and excreted by the kidneys. If the formaldehyde in the body exceeds the detoxification capacity of the liver, it can damage the liver. There have been many reports of acute toxic hepatitis occurring in buildings living in formaldehyde building materials abroad. Although there are few studies on its liver toxicity, it has been confirmed that formaldehyde is potentially toxic to the human liver.

❹Effects on the skin

Mainly cause contact dermatitis and mucosal irritation symptoms. Formaldehyde vapor can come into direct contact with the skin in the air, causing dermatitis, skin redness, severe pain, cracking, and blistering reactions. Repeated irritation can cause nails to soften and turn dark brown. Under occupational exposure conditions, formaldehyde is an important cause of skin damage to workers. A study in Poland showed that occupational, allergic, contact dermatitis (OACD) accounted for 95% of confirmed occupational skin diseases, and among these OACDs, 18.1% is caused by formaldehyde, and this proportion is still increasing.

❺Effects on the endocrine system

Those exposed to formaldehyde may experience tremors, sweaty palms, numbness of limbs, and decreased fingertip touch. Long-term exposure to low-dose formaldehyde (0.017mg/m3-0.0678mg/m3) can also cause menstrual disorders in women.

❻Mutagenic and carcinogenic effects

Formaldehyde is considered a suspected carcinogen by the International Agency for Research on Cancer (IARC). Experiments have shown that formaldehyde can be covalently bound to DNA, showing single-stranded DNA damage. Formaldehyde also produces dominant lethal mutations in mice. Inhalation of high concentrations of formaldehyde in rats can induce nasal squamous cell carcinoma. The carcinogenicity of formaldehyde to the human population remains to be further studied.

❼Effects on the nervous system

Formaldehyde is a neurotoxin. Tests have shown that it can cause degeneration and necrosis of the nervous system and reduce DNA and RNA synthesis. Through the study of long-term anatomical staff, it is found that their memory, sensitivity, balance function, coordination function, etc. have all been reduced to varying degrees. Long-term exposure to formaldehyde may cause symptoms such as headache, memory loss and sleep disturbance to varying degrees.
