Exposure to airborne bacteria and fungi has been linked to various negative health effects. Portable microbial samplers are being increasingly used for monitoring presence of viable bioaerosols; however, data about their performance characteristics are only starting to appear. This study is a continuation of our efforts to analyze and determine various performance characteristics of several portable microbial impactors: SMA MicroPortable, BioCulture, Microflow, Microbiological Air Sampler (MAS-100), Millipore Air Tester, SAS Super 180, and RCS High Flow when collecting bacteria and fungi both indoors and outdoors. All these samplers collect biological particles on agar media and their built-in sampling flow rates range from 30 to 180 L/min. According to our previous studies, the impactors' cut-off size, or d50, range from 1.2 to 7.0 um (Yao and Mainelis, 2006). In this part of the study, we analyzed whether the sampling time affects the overall performance of the portable impactors.
