In the control of clean processes or environments, the real-time detection for biological airborne contaminants is invaluable. Rapid microbiological methods (RMMs) are commonly used in cleanroom environments, but now this method is applied also for indoor air quality measurements in laboratory simulation studies. In the Microdiverbuild project at VTT and UEF, the release and drift of biological, gaseous or other airborne contaminants from hidden mould growth inside the wall structure were studied. RMM was used in real-time measurements of biological and non-biological particles in the Indoor Air Quality simulator (IAQ simulator). The real-time measurement enabled us to follow changes in emissions during dehydration of contaminated material.
