We examined the effect of altering mouthpiece diameter to 1.5, 2.0, and 2.7 cm on the deposition efficiency of inertial size particles (2, 4, and 8 microm) in adult human oral-pharyngeal-laryngeal (OPL) airway cast models at various inspiratory flow

An idea was first introduced during the 1970s that particles cannot produce adverse health effect unless they are inhaled into the human respiratory tract. Since then several studies have been carried out to investigate the inhalable fraction of ambi

Experimental studies of nasal passage deposition were performed in three adult human subjects with ultrafine 218 Po aerosols to determine the inspiratory deposition efficiency of such aerosols. Constant flow rates in the range 5.9–17.51 min −1 we

Objective measures of upper respiratory function are needed to understand the effects of inhaled toxicants on the nasal passages. Acoustic rhinometry (AR) is a simple new technique that determines nasal volume by measuring the cross-sectional area of
