The paper describes preliminary results of a research project to determine the factors that control the release of S. chartarum spores from a contaminated source and test ways to reduce spore release and thus exposure. As anticipated, S. chartarum spore emissions from gypsum board at low flow are directly proportional to airflow and indirectly proportional to relative humidity and support the authors' previous observations with penicillium and Aspergillus. The relationship between the cultural colony-forming units and total spores varied over time and needs further investigation, but suggests one reason that correlation between airborne field measurements (usually only of cultural organisms) and possible exposure is so difficult. (NOTE: Although traditionally, fungi as building contaminants have primarily been viewed as allergens, adverse health effects resulting from inhalation of fungal spores are likely due to multiple factors. One factor is the mycotoxins produced by some fungi.)
