Harm of formaldehyde to pregnant women

Formaldehyde is a colorless gas with a strong pungent smell and is easily soluble in water. Formaldehyde is very harmful to human health, so many pregnant women are worried about the adverse effects of formaldehyde on themselves and their babies. What harm does formaldehyde do to pregnant women? The influence of formaldehyde on pregnant women is mainly manifested in the following points.

1 stimulation

Formaldehyde gives off a strong pungent smell, and its main harm is irritation to skin and mucous membrane. Formaldehyde can be combined with high protein. When people inhale high concentration of formaldehyde, they are prone to severe respiratory irritation and edema, eye irritation, headache and other symptoms. If pregnant mothers stay in an environment that emits formaldehyde for a long time, they will have various discomfort symptoms. At the same time, transportation through the placenta will also endanger the health of the fetus, and if it is serious, it is very likely that there will be dangers such as fetal malformation.

2. Sensitization

Skin contact with formaldehyde can cause allergic dermatitis, pigmentation and skin necrosis. If the human body inhales too high a concentration of formaldehyde, it will also lead to bronchial asthma. Formaldehyde is more harmful to pregnant women, and experts point out that formaldehyde can lead to fetal malformation.

3. Symptoms and manifestations

After inhaling formaldehyde, many people will have different degrees of headache, dizziness, fatigue, nausea, chest tightness, eye pain and other symptoms. In severe cases, it can also lead to palpitation, insomnia, weight loss, memory loss and autonomic nerve disorder.

4. Mutation occurs

High concentration of formaldehyde is a genotoxic substance. In animal experiments, it is found that if animals inhale high concentrations of formaldehyde for a long time, it is likely to induce nasopharyngeal tumors. Therefore, pregnant women should pay attention in their daily lives. If they inhale high concentrations of formaldehyde for a long time, it will not only lead to nasopharyngeal tumors in pregnant women, but also lead to some variation in the fetus.

Effect of formaldehyde on pregnant women

1. Formaldehyde has been identified as carcinogenic and teratogenic by the World Health Organization. It is considered as an allergic allergen and a potential strong mutagen. Long-term exposure of pregnant women to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer, brain tumor, menstrual disorder and nuclear gene mutation.

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, immunity, reproduction and metabolic functions of pregnant women, which will easily lead to symptoms such as headache, fatigue, irritability and insomnia.

3, long-term expectations in a room containing formaldehyde, it is easy to aggravate pregnancy syndrome, nausea and vomiting and other symptoms will be more serious. At the same time, it will also lead to chromosomal abnormalities in newborns, which will eventually lead to congenital defects such as fetal developmental malformation, abortion, impaired fetal brain development, and congenital heart disease.

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

Symptoms of formaldehyde poisoning in pregnant women

1. formaldehyde irritation reaction: transient irritation symptoms of eyes and upper respiratory tract, such as stinging eyes, tears, sore throat, chest tightness, cough, etc. There is no abnormality in chest auscultation and chest radiograph.

2, mild poisoning: obvious eye and upper respiratory tract mucosal irritation symptoms. The main manifestations are conjunctival congestion, redness, dyspnea, heavy breathing, hoarse throat, dry or dull speech or wet greasy. Poisoned people can still feel their breathing getting thicker. Another specific symptom of mild formaldehyde poisoning is one to two degrees of throat edema.

3, moderate poisoning: cough, expectoration, chest tightness, dyspnea and dry and wet broken gongs. During chest X-ray, the lung texture becomes substantial, becoming scattered spots or flaky shadows, which is medical machine-made bronchopneumonia. The edema of throat is aggravated to grade three. Blood gas analysis will be accompanied by mild and moderate hypoxemia.

4. Severe poisoning: the lung and larynx deteriorated, pulmonary edema and fourth degree laryngeal edema, and the blood gas analysis was also serious, which was severe hypoxemia; Symptoms of coma and shock may also occur.

The best way to remove formaldehyde

Generally speaking, indoor environmental pollution is mild and moderate. After the renovation of the new house, the commonly used in addition to formaldehyde methods include activated carbon adsorption, ventilation and plant deodorization.

1, slightly polluted (exceeding the standard 1 times; No key pollution sources, physical treatment): extend the emptying time, strengthen ventilation, often wipe the pollution sources with salt water, and plant green plants that absorb formaldehyde, such as chlorophytum, radish, aloe, ivy, Sanskrit, etc. , and placed activated carbon and other substances that can remove formaldehyde by physical adsorption.

2, moderate pollution (exceeding 2-3 times; There are key pollution sources, which should be treated by physical and chemical methods): While taking the above measures, use reliable formaldehyde scavenger and deodorant to treat pollution release sources, and then put in professional activated carbon that can remove formaldehyde, purify indoor space for a long time, prevent the treatment effect from rebounding, and decompose harmful gases such as formaldehyde for a long time. Deodorizing activated carbon+plant cultivation+ventilation can eliminate pollution.

3. Serious pollution (exceeding the standard by more than 3 times; There are many key pollution sources, indoor comprehensive treatment): It is recommended to choose professional and qualified treatment institutions and implement comprehensive and comprehensive treatment programs. If the pollution is very serious, professional management companies are needed to help deodorize new houses and hotels.

In addition to formaldehyde plants

1, chlorophytum

Chlorophytum has the function of absorbing toxic gases, which is easy to cultivate, adaptable and ornamental. It is one of the hanging plants in most families. Put a pot of chlorophytum in the bedroom, which is beneficial to absorb indoor harmful gases.

2. green radish

Green radish is also an ornamental plant that is easy to cultivate, and it is also an efficient plant that absorbs formaldehyde and purifies the air.

3. aloe oil

Aloe vera is a perennial evergreen succulent plant, which likes warm and dry climate and has weak cold tolerance and shade tolerance. It is not only a good helper to absorb formaldehyde, but also has strong medicinal value and sterilization and beauty effects.

4. Ivy

Ivy is a typical negative plant, which can grow in full light, grow well in warm and humid climate and is not cold-resistant. It is a super in addition to formaldehyde plant.

In addition to the above four common in addition to formaldehyde plants, there are Brahma, agave, hibiscus, chrysanthemum, begonia, Commelina, etc.
