Formaldehyde is a common chemical in our environment. Formaldehyde is a colorless, flammable gas that has a distinct, strong smell.
Everyone is exposed to small amounts of formaldehyde in the air and in some foods and manufactured products. Small amounts of formaldehyde are naturally produced by plants, animals, and humans.
Sources of formaldehyde in the environment include
- Certain manufactured wood products such as cabinets, furniture, plywood, particleboard, and laminate flooring
- Permanent press fabrics (like those used for curtains and drapes or on furniture)
- Household products such as glues, paints, caulks, pesticides, cosmetics, and detergents.
- Smoke from cigarettes and other tobacco products, gas stoves, and open fireplaces.
- Smog
Most people don’t have any health problems from small amounts of formaldehyde in their homes. Exposure to low levels of formaldehyde may irritate your eyes, nose, throat, airways, or skin. Some people are more sensitive than others, so an exposure that causes no problems for some may make other people sick or uncomfortable. People who may be more sensitive to the effects of formaldehyde are the very young, the very old, and people with asthma and other breathing problems.
Exposure to very high levels of formaldehyde over many years has been linked to rare nose and throat cancers in workers. Formaldehyde exposure from new products or new construction in the home would generally be much lower and would last for less time than the exposures linked to cancer.
