Building Materials Used in Construction Can Affect Indoor Fungal Levels Greatly

AIHAJ. Nov-Dec 2000;61(6):895-9. doi: 10.1080/15298660008984603.

Abstract

This article summarizes the results of a fungal investigation of a new, seven-story, 170-room hotel. The owners of the building were refused an occupancy permit by local building officials because of concerns about fungal contamination. This article discusses the processes that were used to investigate and abate the fungal concerns in this building. This investigation involved comparing fungal infestation levels in various building materials, including two different types of gypsum wallboard. During initial testing the indoor air concentrations of problematic fungi were up to 50 times higher than outdoor levels. After the removal of the fungal-infested materials and the replacement with more acceptable materials, the indoor air concentration of problematic fungi dropped to less than one-fourth of outdoor levels.
