- Stimulating effect. When formaldehyde is inhaled too much, severe irritation and edema of the respiratory tract occurs, causing eye irritation, headache, nasal congestion, and nasal pain.
- Sensitization. Frequent inhalation of a small amount of formaldehyde can cause chronic poisoning, causing mucosal hyperemia, skin irritation, allergic dermatitis, keratosis and fragility, and fingertip pain in the nail bed.
- Mutagenicity. Excessive inhalation of formaldehyde can cause nasopharyngeal tumors, as well as leukemia and lymphoma.
- The prominent manifestations are headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, anorexia, palpitations, insomnia, weight loss, memory loss, and autonomic dysfunction.
