Abstract
Rencently, nanotechnology draws
scientists’ eye. The great progresses are in
both knowledge and technology. In aerosol
studies, particle size distribution always plays
a very important role in particle’s behavior,
related to both particle transmission and
health issues. As a consequence, it is
essential to find out the whole story of
smaller particles- nanoparticles. In order to
understand health risk from virus exposure, it
is important to characterize virus aerosols.
In this study, bacteriophages were surrogates
for mammalian viruses in assessing sampling
efficiency of Andersen impactor, impingers,
gelatin filter and Nuclepore filter, as well as
storage effects of virus aerosols in AGI-30
impinger. Our results demonstrated virus
particle morphology and with/without
envelope could significantly affect virus
sampling performance. For hydrophilic
virus, Andersen impactor, impinger, and
gelatin filter are likely to perform better than
Nuclepore filter. The recovery of
lipid-envelope virus sensitive to sampling
stress was indicated to be very low.
