Formaldehyde, the killer of decoration pollution,

  • Detail

The main harm of formaldehyde is to stimulate the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. Formaldehyde concentration greater than 0.08m3 can cause red eyes, itching eyes, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. The newly decorated rooms have high formaldehyde content, which is the main inducement of many diseases

high concentration of formaldehyde is a genotoxic substance. In animal experiments, it was found that if animals inhale formaldehyde in high concentration for a long time, it is likely to induce nasopharyngeal tumors. The following editor will introduce the relevant knowledge of the harm of formaldehyde to pregnant women

the health hazards of formaldehyde mainly include the following aspects:

a stimulation: the main harm of formaldehyde is the stimulation of skin and mucosa. Formaldehyde is a toxic substance in the plasma, which can combine with protein. When inhaled in high concentration, serious irritation and edema of respiratory tract, eye irritation and headache occur

b, sensitization: direct skin contact with formaldehyde can cause allergic dermatitis, stains, necrosis, and bronchial asthma when inhaling high concentrations of formaldehyde

c, mutagenicity: high concentration formaldehyde is also a genotoxic substance. Nasopharyngeal tumors can be caused by high concentration inhalation in laboratory animals

d, prominent manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, throat pain, poor appetite, palpitation, insomnia, weight loss, memory loss and autonomic nerve disorders; Long term inhalation by pregnant women may lead to fetal malformation and even death, while long-term inhalation by men may lead to sperm malformation and death in men

harm of formaldehyde to pregnant women:

1. Formaldehyde has been identified as a carcinogen and teratogenic substance by the World Health Organization. It is a recognized allergen and one of the potential strong mutagens. Long term exposure of pregnant women to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer, brain tumors, menstrual disorders, and nuclear gene mutations

2. When the concentration of formaldehyde in indoor air is higher than 0.24 to 0.55 mg per cubic meter, formaldehyde will also affect the circulatory system, immune, reproductive and metabolic functions of pregnant women, and it is easy to cause headaches, fatigue, fatigue, irritability, irritability, insomnia and other symptoms

3. Staying indoors with formaldehyde for a long time is easy to aggravate pregnancy syndrome, nausea and vomiting and other symptoms will become more serious. At the same time, it will also lead to neonatal chromosomal abnormalities, which will eventually lead to congenital defects such as fetal malformation, abortion, fetal brain development damage, congenital heart disease and so on

4. The most important impact of formaldehyde on pregnant women is that long-term inhalation of formaldehyde by pregnant women can cause increased incidence rate of poisoning during pregnancy, anemia and threatened abortion, as well as low birth weight, deformity and even death of newborns. Therefore, pregnant women should try to reduce exposure to formaldehyde, especially in the first three months of pregnancy

the best way to remove formaldehyde:

generally speaking, indoor environmental pollution is mild and moderate. After the decoration of the new house, the commonly used methods to remove formaldehyde include activated carbon adsorption, ventilation, plant deodorization, etc

1. Slight pollution (within 1 time of exceeding the standard; no key pollution source, physical treatment): extend the drying and vacancy time, strengthen ventilation, often wipe the pollution source with salt water, plant green plants that absorb formaldehyde, such as Chlorophytum comosum, green pineapple, aloe vera, ivy, tiger tail orchid, etc., and place activated carbon and other substances with physical adsorption that can remove formaldehyde

2. Medium pollution (2-3 times higher than the standard; there are key pollution sources, which are treated by physical and chemical methods): while taking the above measures, use reliable formaldehyde scavengers and deodorizers to treat the pollution emission sources, and then place professional activated carbon that can remove formaldehyde to purify indoor space for a long time, prevent the rebound of treatment effect, and decompose formaldehyde and other harmful gases for a long time. Odor removal activated carbon + plant cultivation + ventilation can remove pollution

3. Serious pollution (exceeding the standard by more than 3 times; there are multiple key pollution sources, and indoor comprehensive treatment): it is recommended to select a treatment institution with professional qualifications to implement a comprehensive treatment solution. If the pollution level is very serious, then the new house deodorization and hotel deodorization will need to find a professional management company to help

tips:

1. It is recommended to detect and then treat, so as to accurately understand the degree of indoor pollution and treat symptoms more scientifically

2. The newly decorated house should be ventilated to avoid being in a confined space for a long time

3. The natural release time of formaldehyde is 3 to 15 years. Long-term placement of activated carbon indoors, in furniture, in cabinets, and in drawers is a relatively cheap and practical method to adsorb formaldehyde

summary: through the introduction of the above content, I believe that friends have a comprehensive understanding of the harm of formaldehyde to pregnant women. For more information, please continue to pay attention to the information
