Pulmonary Changes Induced by Ambient Levels of Ozone. A Morphological Study.
Abstract
The objectives were to define the lesions of ambient levels of O3 (0.2, 0.5, and 0.8 ppm) after seven days of intermittent exposure using light microscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM). SEM provided the advantages of observing large tissue samples and correlation of surface alterations with histologic and ultrastructural changes. This study was part of a larger one designed to correlate biochemical and morphological findings following O3 exposure and to compare the effects of continuous and intermittent daily exposure regimes. A portion of the biochemical results and the histochemical results have been published previously (Castleman et al., 1973a; Castleman et al., 1973b; Chow et al., 1974).
