Effects of Formaldehyde
Formaldehyde From Building Materials
Certain building products such as particle board, fiber-
board and hardwood plywood are manufactured with an
adhesive containing urea-formaldehyde. These products
emit a small quantity of formaldehyde into the air.
Other products containing formaldehyde or urea-
formaldehyde resins are some carpets, draperies, uphol-
stery, fabrics, deodorizers, cosmetics and permanent
press fabrics. Formaldehyde is also a by-product of com-
bustion and is produced by cigarettes and gas
appliances.
The concentration of formaldehyde in the indoor air
depends upon the quantity and emission rates of all the
emitting products in the structure compared to the vol-
ume of indoor air and the fresh air ventilation rate. As
with other indoor pollutants, ventilation should reduce
formaldehyde levels.
Formaldehyde levels in the indoor air can cause
temporary eye and respiratory irritation and may
aggravate respiratory conditions or allergies.
