Indoor Plants Can Reduce Formaldehyde Levels

The toxic gas formaldehyde is contained in building materials including carpeting, curtains, plywood, and adhesives. As it is emitted from these sources, it deteriorates the air quality, which can lead to "multiple chemical sensitivity" and "sick building syndrome," medical conditions with symptoms such as allergies, asthma and headaches. The prevalence of formaldehyde and other volatile organic compounds is greater in new construction. Researchers are studying the ability of plants to reduce formaldehyde levels in the air.
