Development of a Guinea Pig Lung Deposition Model

Abstract : Guinea pigs have been used as a surrogate for humans in a number of inhalation toxicology studies by exposing the animals to airborne viruses, biological agents, and other chemicals. Findings from these studies can be extrapolated to humans based on a particular dose-metric of interest to determine potential health effects in humans. In the absence of exposure-dose data, mathematical models can be developed for the transport and deposition of inhaled particles in the lungs of guinea pigs to allow for predictions of lobar, regional, and local deposition of particles.
