If time permits, it is best to soak in the bubble of 1, which can basically wash off the formaldehyde solution. The effects of formaldehyde on human health are mainly manifested in abnormal sense of smell, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function. When its concentration reaches 0.06-0.07 mg per cubic meter of air, children will have mild asthma; When it reaches 0. 1 mg/m3, it has peculiar smell and discomfort; When it reaches 0.5 mg/m3, it can irritate eyes and cause tears; When it reaches 30 mg/m3, it will kill people immediately.

Formaldehyde has a strong stimulating effect on human skin and mucosa, which can coagulate and deform intracellular protein and inhibit the cell cutting performance of 1. Long-term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer and brain tumors. Formaldehyde can cause gene mutation in nucleus, cross-linking in DNA single strand and cross-linking between DNA and protein, and inhibit DNA damage repair; Formaldehyde produces methanol in the body, which has a strong damage to the optic colliculus and retina. It can cause pregnancy syndrome, chromosomal abnormalities in newborns, leukemia, and memory and intelligence decline in adolescents. Among all the contacts, children and pregnant women are particularly sensitive to formaldehyde, which is more harmful.

Formaldehyde is a 1 protoplasm poison that destroys the protein of biological cells. It can damage human skin, respiratory tract and internal organs, anesthetize human central nervous system, and may cause pulmonary edema, hepatic coma and renal failure. The World Health Organization has confirmed that formaldehyde has teratogenic and carcinogenic effects, and long-term exposure will cause gene mutation.
