Formaldehyde. Sources include
durable press drapes and other textiles, particle-board products such as
cabinets and furniture framing, and adhesives. |

To protect yourself and your
family from formaldehyde, find out whether you're at risk. Here are some
common questions and answers.
Q: What is formaldehyde?
A: It is a chemical that is released
into the air as a pungent gas. It has a number of useful properties; it's
a good preservative and makes an excellent adhesive. Therefore, it is used
widely in the building and furnishings industries. It is also found in
small amounts in some textiles as an anti-wrinkle agent.
Q: Why should I be concerned about formaldehyde?
A: It is a strong irritant that causes
watery eyes and in low doses, causes burning sensations in the eyes, nose
and throat. Wheezing and coughing, fatigue, skin rashes, headaches, loss
of coordination and nausea are other symptoms. Larger doses can cause asthma
attacks as well as damage to the liver, kidneys and the central nervous
system. Some people are highly sensitive and react to formaldehyde concentrations
that don't bother most people.
Formaldehyde has been shown to cause cancer in laboratory animals, but
there is limited evidence that it causes cancer in humans.
Q: What are the major sources of formaldehyde?
A: Particle board is the major contributor
of formaldehyde to the home environment. The culprit is the adhesive, urea
formaldehyde, which can break down, releasing the formaldehyde. Phenol
formaldehyde (used in exterior panels) does not present problems. Some
particleboard is now manufactured with reduced formaldehyde.
Other sources include interior plywood, veneered or laminated furniture
and cabinets, some professionally applied furniture and floor finishes,
paneling, permanent press fabrics (some drapes), combustion products and
cosmetics.
Q: How can I detect whether my home has significant
concentrations of formaldehyde?
A: You may be able to detect it by
its odor. Also, environmental testing firms, listed in the yellow pages
of the phone directory, should be able to test for formaldehyde levels.
Since such tests are costly, you should learn whether your home has possible
sources of formaldehyde. Also, do-it-yourself test kits are available,
but there is some question about their accuracy.
Q: What can I do to reduce formaldehyde problems?
A:
-
Formaldehyde cannot penetrate plastic laminate and is at least partly blocked
by coatings.
-
Varnishes and special formaldehyde sealants are also available. Apply these
coatings to all exposed edges and surfaces, such as the undersides of countertops,
cabinet interiors and drawers.
-
High humidity and elevated temperatures cause formaldehyde release, so
you might want to control humidity through air conditioning and dehumidifiers.
-
Increase ventilation, particularly after bringing new sources of formaldehyde
into the home.
-
When remodeling and in new construction, select low formaldehyde materials.
Q: Where can I get more information about formaldehyde?
A: Contact your local Extension Office,
your area Environmental Protection Agency office or your state department
of health. Take action now.
