Mould growth inside buildings

The mould growth inside buildings merits study both in its own right as a natural phenomenon, and because it easily becomes airborne and might pose ahealth problem for certain individuals. The numbers and types of the airborne mycoflora inside buildings depend on air exchange with the outside and the presence of an endogenous mould population. Without intramural mould sources, indoor mould spore levels do, to a major degree, reflect outdoor levels. The existence of endogenous mould growth may result in significant changes in the types of mould present or a major shift in their concentrations. Indoor sampling efforts confront an array of problems. An accurate assessment of the total mould exposure inside buildings require refinement in the sampling procedures to avoid inadequacies of traditional approaches to the studying of indoor fungus prevalence.
