The danger of formaldehyde exceeding the standard
The "Sanitary Standard for Formaldehyde in the Air of the Room" stipulates that the maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/m?. When the formaldehyde content reaches 0.3mg/m?, it will feel obvious odor and discomfort. When it is 0.5mg/m?, the eyes will feel tingling and tearing. 0.6mg/m? will cause throat discomfort or pain. 0.6mg/m? It is prone to nausea, vomiting, cough, chest tightness, gasping and even emphysema .
The hazards of formaldehyde are not caused by a single moment, but also accumulated over a long period of time. As long as there is formaldehyde in the room, every time you inhale a small amount of formaldehyde, the accumulation of less and more may also cause chronic poisoning, and begin to have allergies, skin irritation, nail keratosis and other diseases, easy to lose sleep, headache, palpitations, fatigue and so on.
Formaldehyde damage to children
The molecular weight of formaldehyde is larger than that of air. Therefore, formaldehyde mainly floats within a range of about one meter from the ground. This range is the breathing zone of children. Therefore, the probability and amount of formaldehyde inhaled by children is much larger than that of adults. Because the child is in the developmental stage, the metabolism is faster and more active, the formaldehyde will be inhaled more, and because the child's resistance is weaker, the damage will be greater.
When the baby is inside the mother, if the pregnant woman inhales formaldehyde for a long time, it will easily lead to fetal malformation and even death. Infants and young children, long-term inhalation of formaldehyde, easily affect the hematopoietic function, may lead to leukemia.
