Furniture formaldehyde on the human body what are the hazards?

Formaldehyde is a highly toxic substances, formaldehyde in China's priority control list of toxic chemicals in the second place. Formaldehyde has been identified by the World Health Organization as carcinogenic and teratogenic substances, is recognized as a source of metamorphosis, but also one of the potential strong mutagen. Studies have shown that formaldehyde has strong carcinogenic and cancer-promoting effects. It is well documented that the effects of formaldehyde on human health are mainly manifested in olfactory abnormality, irritation, allergy, lung function abnormality, liver function abnormality and immune function abnormality. When its concentration reaches 0.06 -0.07 mg/ m3 per cubic meter of air, mild asthma occurs in children. When the formaldehyde content in indoor air is 0.1 mg/m3, there is an odor and discomfort; when it reaches 0.5 mg/m3, it can irritate the eyes and cause tears; when it reaches 0.6 mg/m3, it can cause throat discomfort or pain. When the concentration is higher, it can cause nausea and vomiting, coughing and chest tightness, asthma and even pulmonary edema; when it reaches 30 mg/m3, it will cause death immediately. Long-term exposure to low doses of formaldehyde can cause chronic respiratory diseases, cause nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, DNA single-stranded internal cross-linking and DNA and protein cross-linking and inhibit the repair of DNA damage, pregnancy syndrome, cause chromosomal anomalies in newborns, leukemia, and cause memory and mental decline in adolescents. Among all those exposed, children and pregnant women are particularly sensitive to formaldehyde, and the harm is greater. It is the main pollutant of decoration and furniture. Its release period of up to 3-15 years, heat and moisture will volatilize from the deep layers of the material, serious pollution of the environment, has become a difficult to solve the world problem. For the elderly, children and pregnant women are the most harmful.
