Indicator Profile of Formaldehyde in Outdoor Air
Why Is This Important?Formaldehyde, a colorless, pungent-smelling gas, is a chemical used widely to make building materials and numerous household products. It is formed in tobacco smoke, wood smoke and automobile exhaust. In outdoor air, formaldehyde is produced in the atmosphere through chemical reactions between other pollutants and sunlight.
Exposure to elevated levels of formaldehyde in air can cause watery eyes, burning sensations in the eyes and throat, nausea, difficulty in breathing, and asthma attacks. Formaldehyde is classified by the International Agency for Research on Cancer as carcinogenic to humans. Exposure may increase the risk of nasal cancers.
