Why do formaldehyde testing
Why do drugs detect formaldehyde, let's first understand formaldehyde:
Formaldehyde has a pungent odor and can be smelled at low concentrations. The human olfactory threshold for formaldehyde is usually 0.06-0.07mg/m³. But there are large individual differences, some people can reach 2.66mg/m³. Long-term, low-concentration exposure to formaldehyde can cause headaches, dizziness, fatigue, sensory impairment, reduced immunity, drowsiness, memory loss or neurasthenia, and depression; chronic poisoning is also harmful to the respiratory system. Long-term exposure to formaldehyde can cause Causes respiratory dysfunction and liver toxic lesions, manifested as liver cell damage, abnormal liver radiation energy, etc.
The main hazard of formaldehyde is its irritation to the skin and mucous membranes. When formaldehyde reaches a certain concentration indoors, people will feel uncomfortable. The formaldehyde concentration greater than 0.08m³ can cause red eyes, itchy eyes, throat discomfort or pain, hoarse voice, sneezing, chest tightness, asthma, dermatitis, etc. The newly renovated room contains high formaldehyde content, which is the main cause of many diseases.
In layman's terms: Formaldehyde mainly affects human immune function. At present, there are medical reports showing that immune diseases are related to formaldehyde, such as leukemia, aplastic anemia, etc.;
Research animals found that exposure of rats to 15μg formaldehyde per cubic meter for 11 months can cause nasal cancer. A new study published by the National Cancer Institute of the United States on May 12, 2009 shows that chemical plant workers who are frequently exposed to formaldehyde are more likely to die from cancers such as blood cancer and lymphoma than workers who are less exposed to formaldehyde. Researchers surveyed 25,000 workers in chemical plants that produce formaldehyde and formaldehyde resins, and found that among workers, those with the most exposure to formaldehyde had a 37% higher mortality rate than those with the least chance. Researchers analyzed that long-term exposure to formaldehyde increased the risk of developing specific cancers such as Hodgkin's lymphoma, multiple myeloma, and myelogenous leukemia.
