Bioaerosols - where should one measure them in a room?

Bioaerosol measurements are performed to assess the exposure to micro-organisms in a room. Literature however reveals little consensus on the procedure with which measurements are made. Comparison of individual results therefore remains difficult. This paper tries to initiate the development of a procedure for performing bioaerosol measurements. As a first step the measurement location in a room is considered. Through bioaerosol measurement and CFD modeling knowledge is gained on the bioaerosol contaminant distribution in a room and the parameters that play an important role. From these results an onset is given for a procedure to determine the measurement location. The indoor air flow pattern and the (possible) source location are the main parameters in this context. The procedure is set up more broadly and includes for example a questionnaire. It is the intention to elaborate on the development of this procedure in future projects.
