What are the symptoms of formaldehyde and benzene poisoning?

Under normal circumstances, formaldehyde and benzene are two common volatile organic compounds, and exposure to them may lead to poisoning. Symptoms of formaldehyde poisoning include respiratory irritation, eye irritation, skin discomfort, nasal irritation, and systemic symptoms; symptoms of benzene poisoning include respiratory system symptoms, nervous system symptoms, digestive system symptoms, hematopoietic system symptoms, and immune system symptoms. A detailed analysis is as follows:

I. Symptoms of Formaldehyde Poisoning

1. Respiratory Irritation
Formaldehyde is strongly irritating. Prolonged exposure or contact with high concentrations may cause respiratory symptoms such as sore throat, coughing, difficulty breathing, and wheezing.

2. Eye Irritation
After exposure to formaldehyde, the eyes may experience burning, redness, pain, tearing, dryness, and blurred vision.

3. Skin Discomfort
Prolonged contact with formaldehyde may lead to skin irritation, including rashes, redness, itching, dryness, and erosion.

4. Nasal Irritation
Exposure to high concentrations of formaldehyde may cause nasal irritation, manifesting as nasal congestion, runny nose, sneezing, and nosebleeds.

5. Systemic Symptoms
Long-term exposure to high concentrations of formaldehyde may result in general discomfort, including headache, fatigue, palpitations, insomnia, difficulty concentrating, and memory decline.

II. Symptoms of Benzene Poisoning

1. Respiratory System Symptoms
Long-term or high-concentration exposure to benzene may cause respiratory problems, such as shortness of breath, wheezing, coughing, and chest tightness.

2. Nervous System Symptoms
Benzene is toxic to the central nervous system. Long-term exposure may lead to dizziness, headache, difficulty concentrating, insomnia, fatigue, depression, and memory impairment.

3. Digestive System Symptoms
Benzene poisoning may also be associated with digestive issues, including nausea, vomiting, loss of appetite, and abdominal pain.

4. Hematopoietic System Symptoms
Long-term exposure to benzene may adversely affect the hematopoietic system, potentially leading to anemia, reduced platelet count, and increased tendency to bleed.

5. Immune System Symptoms
Prolonged exposure to benzene may impair immune system function, resulting in increased susceptibility to infections and decreased immunity.

It should be noted that the above symptoms are common manifestations associated with formaldehyde and benzene poisoning, but specific symptoms and their severity may vary depending on individual differences, concentration of exposure, and duration. If you suspect you have symptoms of poisoning, it is recommended to seek medical attention promptly to avoid delays in treatment.
