Inhalation of formaldehyde during pregnancy
First of all, we should get rid of the environment where formaldehyde is increasing, and then go to the hospital for examination. After diagnosis, you can treat the symptoms and pay attention to your diet.
Harm of formaldehyde to pregnant women
If pregnant women inhale high concentrations of formaldehyde, bronchial asthma may occur, and symptoms such as severe irritation of respiratory tract, headache, stinging eyes and edema may also occur. Direct contact of pregnant women's skin with formaldehyde can cause dermatitis, pigmentation and necrosis. In addition, if pregnant women inhale formaldehyde for a long time, it may lead to pregnancy syndrome, pregnancy poisoning, anemia, neonatal chromosomal abnormalities, leukemia and other diseases, and may also increase the incidence of threatened abortion, which may lead to low birth weight, malformation and even death of newborns. At the same time, even if the amount of inhalation is small, it may cause chronic poisoning, allergic dermatitis, skin irritation, mucosal congestion, nail bed pain, nail keratinization and fragility and other systemic symptoms, such as fatigue, insomnia, headache, palpitation, weight loss, autonomic nervous disorder and poor appetite. So, how to prevent pregnant women from absorbing formaldehyde for a long time?
Preventive methods of formaldehyde inhalation in pregnant women
The newly renovated house is the biggest harm. At this time, the home contains a lot of toxic gases such as formaldehyde, and the incubation period of toxic gases is very long, which is the most serious in the first year. During this period, toxic gases volatilize quickly and release a lot, which is the most serious harm to human body. For the sake of health, generally speaking, we have to ask newly renovated houses to move in after three months or half a year. Before moving in, we also have to ask professional environmental protection companies to carry out indoor air testing and equip air purifiers to purify indoor air.
Harm of formaldehyde
Although formaldehyde has the following health hazards:
A. irritation: the main harm of formaldehyde is 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.
B. Sensitization: Direct skin contact with formaldehyde can cause allergic dermatitis, pigmentation and necrosis, and inhalation of high concentration formaldehyde can induce bronchial asthma.
C. 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.
D, outstanding manifestations: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, loss of appetite, palpitation, insomnia, weight loss, memory loss, autonomic nervous disorder; Long-term inhalation by pregnant women may lead to fetal malformation or even death, while long-term inhalation by men may lead to male sperm malformation or even death.
However, because the human body has the function of self-repair, it can metabolize formaldehyde in the inhaler. As long as you stay away from the toxic environment for a period of time, the symptoms will disappear, but staying in an environment with excessive formaldehyde concentration for a long time will damage the respiratory system and even cause cancer.
