What will happen if you inhale formaldehyde?

As people's living standards continue to improve, everyone is paying more and more attention to health awareness. In daily life, there are many invisible health killers around us, and formaldehyde is relatively common. Formaldehyde is always everywhere in our lives. Decoration materials, clothes, children's toys, etc. will all have formaldehyde. So what kind of reaction will the body usually have if you inhale formaldehyde?

What will happen if you inhale too much formaldehyde?

Dangerous!

Causes burns to skin, eyes, and digestive tract

Prolonged and repeated skin contact can cause death or blindness.

May be fatal or cause blindness if swallowed.

Causes respiratory tract, throat, skin and eye irritation.

Harmful if inhaled.

May cause allergic respiratory and skin reactions. ?Flammable liquids and vapors.

Suspected risk of cancer. Contains substances that may cause cancer. The risk of cancer depends on the duration and level of exposure. Potential Health Effects Routes of Exposure: Skin, Eyes, Inhalation, Ingestion.

Direct impact:

Skin: Causes skin burns. May cause an allergic skin reaction. Harmful if absorbed through skin. Symptoms of exposure may include: central nervous system depression headache numbness incoordination or strange behavior or unconsciousness. Redness or discoloration, swelling, itching, burning, or blistering of the skin. Prolonged and/or repeated skin contact with methanol-soaked materials can produce toxic effects including visual effects and death.

Eyes: Exposure to liquid causes severe, irreversible burns to eyes. Exposure to vapor causes eye irritation. Symptoms of exposure may include: eye stinging, burning, pain, watering, and/or altered vision.

Inhalation: Causes respiratory tract irritation. Harmful if inhaled. May cause allergic respiratory reactions. Symptoms of exposure may include: central nervous system depression nausea, dizziness, headache, numbness, incoordination or strange behavior or unconsciousness. Nasal discharge, hoarseness, cough, chest pain and difficulty breathing. Accumulation of fluid in the lungs (pulmonary edema); symptoms may be delayed for several hours. Adversely affects vision.

Ingestion: Causes gastrointestinal burns. Harmful if swallowed. Symptoms of exposure may include: central nervous system depression nausea, dizziness, headache, numbness, incoordination or strange behavior, or unconsciousness. Nausea, vomiting, loss of appetite, gastrointestinal irritation and/or diarrhea. Severe damage to mouth, throat, esophagus and/or stomach. Reproduction: May cause adverse reproductive effects based on animal data. Carcinogenicity:

Chronic or repeated inhalation of formaldehyde can cause excessive nasal tumors based on laboratory rat studies and limited human data. Studies of human exposure to formaldehyde have had mixed results, demonstrating an association between leukemia and formaldehyde exposure.

What harm will inhaling too much formaldehyde do to the body?

Formaldehyde is a highly toxic substance and ranks second on my country's priority control list of toxic chemicals. Formaldehyde has been identified by the World Health Organization as a carcinogen and teratogen. It is a recognized source of allergies and one of the potential strong mutagens.

Studies have shown that formaldehyde has strong carcinogenic and cancer-promoting effects. A large number of documents record that the effects of formaldehyde on human health are mainly manifested in abnormal smell, irritation, allergy, abnormal lung function, abnormal liver function, etc. When the formaldehyde concentration in indoor air reaches 0.06-0.07 mg/m3, children will have mild asthma; when it reaches 0.1 mg/m3, there will be odor and discomfort; when it reaches 0.5 mg/m3, it may irritate the eyes and cause tears; when it reaches 0.6 mg/m3, it may cause throat discomfort or pain; when the concentration is higher, it may cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema; when it reaches 30/m3, it will cause immediate death.

Long-term exposure to low doses of formaldehyde can cause various chronic respiratory diseases, cause memory and intelligence decline in adolescents; cause nasopharyngeal cancer, colon brain tumors, nuclear gene mutations, inhibition of DNA damage repair, menstrual disorders, pregnancy syndrome, newborn chromosomal abnormalities, and even cause leukemia. Among all those who are exposed to formaldehyde, children, pregnant women and the elderly are particularly sensitive to formaldehyde and are therefore more vulnerable to harm.
