| Abstract | Small laboratory animal models have been widely used by environmental toxicologists to investigate the potential health hazard of air pollutants. With few exceptions, during the exposure to the pollutants the animals were at rest. In the natural environment the population at risk is not always at rest, but in contrast, is frequently active. This study was undertaken to determine if exercise during exposure to a gaseous air pollutant would increase the risk resulting from the inhalation of viable organisms. Two groups of mice were exposed to either 0.3, 0.2 or 0.1 ppm of ozone or 3.0, 2.0 or 1.0 ppm of nitrogen dioxide for 3 hr. One group of animals were at rest while the second was on a newly designed mechanized exercise wheel. After the exposure to the gas the groups were combined and together they were then exposed, while at rest, to an aerosol of viable microorganisms. A significant increase in mortality was noted in the exercise animals as compared to those at rest. |
