where does formaldehyde come from
The chemical symbol for formaldehyde is CH2O. Formaldehyde is released into the air by burning wood, kerosene, or natural gas; from automobiles and diesel exhaust; and from cigarettes and other tobacco products. It is found in the air at home, at work, and outdoors, especially in smog. It is also found in some foods.
There is usually more formaldehyde present indoors than outdoors. Formaldehyde is released to the air from many home products and you may breath in formaldehyde while using these products. Latex paint, fingernail hardener, and fingernail polish release a large amount of formaldehyde to the air.
