Is it serious if the formaldehyde exceeds the standard by twice?

Everyone knows that formaldehyde is very harmful to the human body. If people are in a formaldehyde environment for a long time, it will not only affect their health, but may also endanger their lives and cause cancer. Formaldehyde is very toxic. It seems that there will be no harm in a short period of time when formaldehyde exceeds the standard by twice, but over time, formaldehyde will invade the human body, cause cancer, and affect health.

Formaldehyde is a highly toxic substance and ranks second on my country's priority control list of toxic chemicals. It has been identified by the World Health Organization as a carcinogen and teratogen, is a recognized source of allergies, and is also one of the potential strong mutagens. Studies have shown that formaldehyde has strong carcinogenic and cancer-promoting effects. A large number of documents record that the effects of formaldehyde poisoning on human health mainly manifest in abnormal smell, stimulation, allergy, abnormal lung function, abnormal liver function and abnormal immune function.

When its concentration reaches 0.06-0.07 mg/m3 per cubic meter of air, some sensitive children will experience mild asthma. When the indoor air concentration reaches 0.1 mg/m3, there will be odor and discomfort; when it reaches 0.5 mg/m3, it may irritate the eyes and cause tears; when it reaches 0.6 mg/m3, it may cause throat discomfort or pain. Higher concentrations can cause nausea and vomiting, coughing, chest tightness, asthma and even pulmonary edema; when the concentration reaches 30 mg/m3, it can cause immediate death.

The hazards of long-term exposure to low doses of formaldehyde include: causing chronic respiratory diseases, nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the cell nucleus, cross-linking within the single strand of DNA and between DNA and protein, inhibition of DNA damage repair, pregnancy syndrome, causing chromosomal abnormalities and leukemia in newborns, and causing memory and intellectual decline in adolescents.

Among all those exposed to formaldehyde, children and pregnant women are particularly sensitive to formaldehyde and are more harmful to it. It is the main pollutant in decoration and furniture. The release period is as long as 3-15 years. When exposed to heat or moisture, it will evaporate from deep within the material, seriously polluting the environment and causing the greatest harm to the elderly, children and pregnant women. 520 Air Gas Station recommends that for the sake of your family’s health, you must find a professional indoor environment testing and management company for services before moving into a new home to ensure that the air quality meets national standards.
