Formaldehyde has pungent smell, which can be smelled at low concentration. The olfactory threshold of formaldehyde is usually 0.06-0.07mg/m3. However, there are great individual differences, some of them can reach 2.66mg/m3. Long term and low concentration exposure to formaldehyde will cause headache, dizziness, fatigue, sensory impairment, immunity reduction, drowsiness, memory loss or neurasthenia, mental depression; chronic poisoning is also a great harm to the respiratory system, long-term exposure to formaldehyde can cause respiratory dysfunction and liver toxic lesions, manifested as liver cell damage, abnormal liver radiation energy, et
