Abstract
Mice were exposed to fly ash particles (<2.1 μm diameter) by inhalation for variable amounts of time at concentrations ranging from 535 to 2221 μg/m 3. This fine fraction was approximately 32% by weight of the total dust generated. The effects of these exposures were assessed on macrophage-mediated functions. Phagocytosis of bacterial cells by the alveolar macrophages was depressed in the fly ash-exposed animals as was the ability to enhance T-cell mitogenesis. Fly ash exposure failed to produce a significant change in the cellular immune response (delayed-type hypersensitivity reaction) to antigenic challenge in the lungs of sensitized animals.
