Formaldehyde (also known as methanal),
is a gas at room temperature and has a strong pungent smell. Its chemical
formula is H2CO. It is soluble in water, and it is
commonly sold as a 37% solution in water under trade names such
as
formalin or formol.
Formaldehyde is used a preservative in medical laboratories, as
an embalming
fluid, and as a sterilizer. Non-medical uses of this
chemical include the the production of resins, and
as a chemical intermediate.
When present in the air at levels at or above 0.1 ppm, formaldehyde can
lead to acute health
effects, such as watery eyes; burning sensations in
the eyes,
nose and throat; nausea; coughing; chest tightness; wheezing; skin rashes;
and other irritating effects. Formaldehyde can affect people in various
ways. Sensitive
people can experience symptoms at levels below 0.1 ppm. Note that the list of chemicals included
