The injury of human body is many, and high-concentration formaldehyde is also toxic to nervous system, immune system, liver etc..Formaldehyde is to human body
Injury can also be through a variety of ways:Formaldehyde can be absorbed through respiratory tract, suck high-concentration formaldehyde after, it may appear that respiratory tract it is tight
Sharp and oedema, eye shouting pain, headache are remised, bronchial asthma can also occur.Direct skin contact high-concentration formaldehyde can cause skin
Inflammation, color spot, necrosis.Its aqueous solution " formalin " can be absorbed through alimentary canal.
A small amount of formaldehyde is often sucked, slow poisoning can be caused, chronic respiratory disease can be caused, mucous membrane is congested, skin
It stimulates the symptoms such as disease, allergic dermatitis angling and fragility, nail matrix finger tip pain or even causes nasopharyngeal carcinoma.For women, warp
Often suck a small amount of formaldehyde, in fact it could happen that feminine menstrual is disorderly, and sucking may cause pregnancy syndrome to pregnant woman for a long time, cause newborn
Constitution reduces, chromosome abnormality, ewborn infant deformity or even death.Man's sucking for a long time can cause man's teratospermia, dead
It dies, sexual function declines, serious to cause leukaemia, pneumothorax, and fecundity missing, constitutional symptom has headache, weak, stomach to receive
Difference, palpitaition, insomnia, weight loss and vegetative nervous disorder etc..The people of Long Term Contact formaldehyde can cause nasal cavity, oral cavity, nose
Pharynx, throat, skin and gastral cancer.
Formaldehyde is considered as a kind of suspecious carcinogen to rank the first in indoor pollution always, is typically derived from decoration, dress
