Formaldehyde
can be produced from burning materials containing carbon. Contented in smoke
from forest fires, car exhaust and tobacco smoke. In the atmosphere of earth,
the formaldehyde produced by the action of sunlight and oxygen to the methane
and hidrocarbonmetabolitorganism, including humans. With others in the
atmosphere. In the formaldehyde content also produced very small as most.
Although
the free formaldehyde in the air in gas form, but can be dissolved in water
(usually sold in 37% solvent content using the trademark or formalin formol). In
water, formaldehyde polimerisasi experience, very few existing in the form of
monomer H2CO. Generally, this solution contains a few percent metanol to limit
the polymerization. Formalin is formaldehyde solution in water, with the rate
between 10% -40%.
Although
formaldehyde show nature in general, such as chemical aldehyde, this compound
more reactive than other aldehyde. Formaldehyde is elecktrofill, can be used in
the aromatic substitution reaction elektrofilik and aromatic substance and may
experience a reaction addition elektrofilik and alkena. Because the situation
hydro catalyst, formaldehyde can produce an acid reaction Cannizaro format and
metanol.
Formaldehyde
can form a trimer cyclic, 1,3,5-trioksan or polymer linier polioksimetilen.
Formation of this substance makes the behavior of formaldehyde gas is different
from the ideal gas law, especially in high-pressure air or cold. Formaldehyde
can be oxidated by oxygen atmosphere clabber format, because the formaldehyde
solution and diisolasi have to be closed so that air is not possessed.
The influence of the Board
Because
formaldehyde resin used in construction materials such as plywood / triplex,
carpet, and spray foam insulation and, because the resin and this release
formaldehyde slowly, formaldehyde is a pollutant in the room which is often
found. If the measure in the air more than 0.1 mg / kg, which is absorbed
formaldehyde can cause an irritation of mukosa head membrane, which caused the
water out the eyes, dizziness, sore throat, and mugginess.
If
exposed to formaldehyde in the number of lots, terminum for example, can cause
death. In the human body, formaldehyde is converted format so acid that
increase the acidity of blood, draw a short breath, and often, hypothermia, also
commas, or, to the death.
In
the body, formaldehyde can tie DNA by protein, so that the genetic expression
of normal. Animal experiments that suck formaldehyde steadily fell ill cancer
in the nose and the throat, as well as experienced by employees cutting board
articles. However, there are studies that show when the formaldehyde content in
the less, as used in the building, does not cause influence carcinogenic
against living creatures that are exposed to oxygen.
First occurs when the acute toxication
First
depending on the concentration of liquids and symptoms experienced by the
victims. Prior to the hospital, give active charcoal (norit) when available. Do
not make the stimulus so that the victim vomits, because it will cause a risk
of trauma to the corrosive channel digested over. Usually in the hospital
medical team will perform Rinse stomach (gastric lavage), to give active
charcoal (although the provision of active charcoal will disrupt vision at
endoscopy). Endoscopic action is to diagnose the occurrence of trauma esofagus
and digested channel. Formalin to increase the elimination of the body can be
done hemodyalisis (wash the blood). This action is required if the victim shows
signs acidosis metabolic weight.
