Abstract
There is growing evidence that fine particulate matter may have adverse effects on respiratory health, but convincing human exposure studies are lacking. The present thesis describes preliminary research in which four human subjects were exposed for two hours on four separate occasions each to particle-filtered air and to three target levels of concentrated ambient fine particles (20, 40, and 60 [mu]g/m3) in a human exposure facility using a new and innovative particle delivery method. Diffusing capacity for CO, body plethysmography, and spirometry when carried out before and after exposure. Spirometry was also carried out during each exposure. Results suggested that the facility could effectively be used for human exposures to concentrated fine ambient particles while maintaining adequate conditions of safety and comfort, and that two-hour exposures up to target concentrations of 60 [mu]g/m3 did not adversely alter lung function in the subjects tested.
