Excerpt
Introduction: The relationship between repeated air pollutant exposures and the response of the respiratory tract is a complex but important aspect of toxicologic assessment involved in the proper setting of environmental exposure standards. The reason for this is that any organ system of the body has a limit as to the amount and duration of insult that can be withstood before its defenses are overwhelmed and pathology results. Recent studies performed in this laboratory have examined temporal changes in the tracheobronchial tree from repeated exposures to the common atmospheric irritant, sulfuric acid mist (1-3). Sulfuric acid (H2S04) is often a significant component of the ambient accumulation mode aerosol in urban and rural areas (4); thus, large and very diverse populations are exposed to this pollutant. In addition, it has been suggested that exposure to HzS04 may be a contributor to the pathogenesis of chronic bronchitis (5).
