Indoor viable particles sampling with size separation

Abstract Airborne viable microorganisms may cause health problems in work and generally indoor environments. Since the ability of following air movements is related, also for these aerosols, to particle size, detailed informations of the size distribution is helpful in the assesment of inhalability (penetration into the airways) and subsequent infectious microorganisms dissemination (regional deposition) into the airways. A study on the application of a personal spectrometer is presented.
