Abstract |
Estimations of regional pulmonary doses of O3 and NO2 need to be combined with an understanding of the sensitivity of several animal species and man to equivalent tissue doses before animal to man quantitative extrapolations can be performed. Because of potential species differences in anti-oxidant defenses and repair mechanisms it is unlikely that regional lung dose-response effects will be identical across species. These differences will be discussed and unifying concepts presented that are likely to quantitatively accomodate the differences in eventual extrapolation modeling. The concepts and their current state of experimental or theoretical validation to be addressed include the application of (1) scaling principles between species following in vitro and in vivo exposure, (2) the parallelogram concept which directly relates acute animal to acute human effects and acute animal to chronic animal effects, thereby permitting the indirect estimation of chronic human effects, and (3) species comparisons of the health effects of O3. |
