Introduction
In general, childhood formaldehyde poisoning can be detected through environmental testing, clinical symptoms, blood tests, urine tests, and chest X-rays. If a child is suspected of formaldehyde poisoning, it is recommended to immediately remove them from the formaldehyde-exposed environment to prevent worsening of symptoms. Prompt medical attention should also be sought for appropriate treatment, in order to avoid harm to the body.
In general, children suspected of formaldehyde poisoning can be evaluated through environmental testing, clinical symptoms, blood tests, urine tests, and chest X-rays. The specific analysis is as follows:
1. Environmental Testing
Testing the formaldehyde concentration in a child's living environment is a common method. Professional environmental testing agencies can use formaldehyde detection instruments to monitor the concentration of formaldehyde in indoor air, thereby determining whether levels exceed safe limits.
2. Clinical Symptoms
Formaldehyde is an irritant substance. Inhalation may irritate the eyes and mucous membranes of the upper respiratory tract, causing inflammatory reactions such as conjunctival congestion, dryness and itching of the throat, and difficulty breathing. These clinical symptoms can help in diagnosis.
3. Blood Test
Blood tests can assess the extent of a child's exposure to formaldehyde. This method involves collecting a blood sample from the child and using specific techniques to measure the concentration of formaldehyde in the blood.
4. Urine Test
By analyzing metabolites of formaldehyde in the urine, the level of formaldehyde exposure in the body can be assessed. This test typically requires collecting a urine sample from the child and sending it to a laboratory for analysis.
5. Chest X-ray
After inhaling formaldehyde, symptoms may include persistent coughing and phlegm production; severe cases may develop emphysema. A chest X-ray can effectively identify these conditions, helping to determine whether formaldehyde poisoning has occurred.
If a child shows signs of formaldehyde poisoning, it is recommended to immediately remove them from the formaldehyde-contaminated environment to prevent worsening symptoms. Prompt medical attention should also be sought for appropriate treatment to avoid harm to the body.
