Particle Deposition onto People in a Transit Venue.

摘要: Following the release of an aerosolized biological agent in a transit venue, material deposited on waiting passengers and subsequently shed from their clothing may significantly magnify scope consequences such attack. Published estimates relevant particle deposition resuspension parameters for complex indoor environments as facility are nonexistent. In this study, measurements velocity onto cotton fabric samples affixed to stationary walking people large multimodal were obtained tracer releases carried out part larger study subway airflows particulate transport. Deposition velocities wool also using novel automated sampling mechanism deployed at locations throughout subway. The data revealed higher than have been previously reported exposed test chambers or office environments. relatively high rates venue suggest it is possible that fomite transport by commuter/regional rail could present significant rapidly dispersing metropolitan area beyond.
