The health effects of ozone (O/sub 3/) and nitrogen dioxide (NO/sub 2/) are assessed from animal toxicological, controlled human, and epidemiological studies. These assessments will be strengthened when results of animal studies can be quantitatively extrapolated to man. To achieve quantitative extrapolation, improvements are needed in the areas of dosimetry and species sensitivity. And, of course, an adequate health effect data base must exist on which to make extrapolations. The focus of this paper is to review the regional dosimetry of O/sub 3/ and NO/sub 2/ in the respiratory tract of man and animals. Dosimetry relates to estimating the amount of pollutant reaching a specific target region of the respiratory tract as a function of exposure concentration. At present, there are two approaches to dosimetry, experimental and mathematical modeling, which are discussed.
