Increasing attention is becoming focused on fungi in indoor environments. Although most of the molds occurring in human environments occur indoors, the interior of buildings are themselves a special habitat. It has long been known that indoor fungi cause allergies in sensitive persons, but only relatively recently have indoor molds been linked to other health problems. While allergy sufferers generally react to substances in fungal spores, other health problems may be caused by volatile substances released by molds into the air.
