Inhaled acidic sulfate aerosols affect various aspects of lung function, presumably by delivery of hydrogen ion (H+) to target sites. Recent evidence suggests that the relationship between response and H+ content of the exposure atmosphere may depend upon the specific

The purpose of this study was to examine a broad range of toxicologic responses in rats exposed to a multi-component pollutant atmosphere. Cumulative and adaptive respiratory tract responses to 3 concentrations of an inhaled particle-oxidant mixture were examined in Fisher
