1, stimulate the human body. People are exposed to formaldehyde in a short time, and adults generally show sore throat, poor breathing and respiratory inflammation. But children will have symptoms earlier than adults, because the floating position of formaldehyde in the air is close to the height of children, and children are more likely to inhale formaldehyde.
2, it will produce allergic symptoms. If our skin is exposed to formaldehyde for a long time, it will cause allergic dermatitis and pigmentation, and in severe cases it will lead to skin necrosis. If asthma patients inhale formaldehyde, it will cause diseases such as bronchial asthma.
3, causing malignant diseases. If people inhale formaldehyde for a long time, it will induce gene mutation and turn normal cells into cancer cells, tumors, leukemia and so on. Because children have poor resistance, strong absorption ability and poor discharge ability, formaldehyde is more harmful to children.
So formaldehyde is very harmful to people's health. After the house is renovated, it must be left vacant for a period of time to remove the formaldehyde in the room, and then move in when the formaldehyde reaches the standard.
