What are the performance of formaldehyde exceeding the standard?

11、 Although do not smoke, but often feel throat discomfort, foreign body feeling, respiratory obstruction;
Family members have common diseases, and symptoms will obviously change and improve after leaving this environment.
As a common product in decorative furniture and building materials, the harm of formaldehyde is self-evident. As early as 2004, the substance was upgraded to category 1 carcinogen by the international agency for research on cancer (IRC), which is the most likely carcinogen. In addition, formaldehyde may also induce leukemia, leading to pregnancy abortion, fetal malformation.
The main harm of formaldehyde is the irritation to skin and mucous membrane. When formaldehyde reaches a certain concentration indoors, people feel uncomfortable. If formaldehyde concentration is too high, it can cause acute poisoning, such as sore throat, dyspnea, pulmonary edema, allergic purpura, allergic dermatitis, elevated liver transaminase, jaundice, etc.
Formaldehyde has a pungent odor, which can be detected at low concentration. The olfactory threshold of formaldehyde is usually 0.06-0.07mg/m3. However, the individual difference is large, some of them can reach 2.66mg/m3. Long term exposure to low concentration of formaldehyde can cause headache, dizziness, fatigue, sensory disturbance, decreased immunity, drowsiness, memory loss, neurasthenia and mental depression; chronic poisoning also has great harm to respiratory system. Long term exposure to formaldehyde can cause respiratory dysfunction and liver toxic lesions, manifested as liver cell damage and abnormal liver radiation energy.
Formaldehyde can cause nuclear gene mutation, chromosome damage and 0 "8 breakage. Formaldehyde and other polycyclic aromatic hydrocarbons (PAHs) have combined effects, such as benzopyrene, which will increase the toxicity.
Easy to cause cancer
Animal studies have found that exposure to 15 grams of formaldehyde per cubic meter for 11 months may lead to nasal cancer in rats. Workers exposed to formaldehyde are more likely to die from blood and lymph cancer than workers exposed to less formaldehyde, according to a new study released on May 12, 2009 by the International Cancer Institute. The researchers surveyed 25000 workers in chemical plants that produce formaldehyde and formaldehyde resin, and found that the workers exposed to the most formaldehyde had a 37% higher risk of death than those who had the least exposure to formaldehyde. Long term exposure to formaldehyde increases the risk of specific cancers, such as Hodgkin's lymphoma, multiple myeloma and myeloid leukemia, the researchers said.
