Background

Spores and microscopic fragments of mold growth are a natural component of both outdoor and indoor air. However, when molds germinate and grow, they can produce large amounts of spores. Recently, concern has arisen that elevated levels of mold spores in indoor living or working environments may increase the risk of adverse health effects, particularly respiratory problems. EHIB staff has prepared review documents summarizing currently available knowledge regarding the occurrence of molds and possible human health effects. This page allows access to these documents and provides links to other sites with helpful information regarding molds and other indoor air contaminants.
