Introduction
Under normal circumstances, formaldehyde is a toxic irritant that can be harmful to the human body with long-term exposure, primarily causing damage to the eyes, skin, respiratory system, nervous system, and immune system. High-concentration formaldehyde vapor can cause eye discomfort, burning pain, redness, swelling, and tearing. Prolonged exposure may exacerbate eye problems and lead to ocular diseases such as conjunctivitis and keratitis.
Under normal circumstances, formaldehyde is a toxic irritant that can be harmful to the human body with prolonged exposure. It primarily damages the eyes, skin, respiratory system, nervous system, and immune system. Specific effects are as follows:
1. Eyes
Exposure to high concentrations of formaldehyde vapor can cause eye discomfort, burning pain, redness, swelling, and tearing. Prolonged exposure may worsen eye conditions and lead to diseases such as conjunctivitis and keratitis.
2. Skin
Exposure to high levels of formaldehyde may cause skin irritation and allergic reactions, resulting in rashes, redness, itching, and dry skin.
3. Respiratory System
Long-term exposure to high concentrations of formaldehyde may lead to respiratory problems such as sore throat, coughing, asthma, shortness of breath, and an increased risk of upper respiratory tract infections.
4. Nervous System
Chronic inhalation of formaldehyde can damage the nervous system, causing symptoms such as dizziness, headache, fatigue, insomnia, and drowsiness.
5. Immune System
Prolonged exposure to formaldehyde may weaken immune function, making the body more susceptible to infections and illnesses. Patients may frequently experience colds, fever, and similar symptoms.
If formaldehyde poisoning occurs, prompt medical attention is recommended to avoid delays in treatment. To prevent harm to health, it is advisable to avoid environments containing formaldehyde.
