formaldehyde poisoning
Introduction
Introduction to formaldehyde poisoning Formaldehyde poisoning is a systemic formaldehyde poisoning disease caused by exposure to high concentrations of formaldehyde vapor, which is mainly caused by eye and respiratory damage. The effects of formaldehyde on human health are mainly manifested in olfactory abnormalities, irritation, allergies, abnormal lung function, abnormal liver function and abnormal immune function. The long-term exposure to low-dose formaldehyde is caused by chronic respiratory diseases, causing nasopharyngeal cancer, colon cancer, brain tumors, menstrual disorders, nuclear mutations, DNA single-strand cross-linking, and DNA-protein cross-linking and inhibition of DNA damage. Repair, pregnancy syndrome, causing neonatal chromosomal abnormalities, leukemia, causing memory and mental decline in adolescents. basic knowledge The proportion of sickness: 0.01%-0.018% Susceptible people: no special people Mode of infection: non-infectious Complications: pulmonary edema
