An aerosol exposure system and procedures for delivering asbestos cement (AC) dust to the lungs of hamsters are described. Groups of hamsters were exposed to AC aerosol concentrations of 1 and 10 μg/liter, respectively, 3 hr/day, 5 days/week, for 3

We have designed a nose-only inhalation exposure chamber in which fresh aerosol is flowed past each exposure port and exhaled air is immediately exhausted. This allows all animals in the chamber to be exposed to the same aerosol concentration. In tes

The carcinogenicity of inhaled, submicron-sized, high-fired 239-plutonium dioxide and beryllium oxide particles was examined in over 600 rats, following single nose-only exposure to initial alveolar depositions of 1.0–91 wg beryllium and of 4–180
