A simple and inexpensive dustfeed mechanism has been designed for use with a two-phase fluidized bed generator (FBG). The mechanism is especially useful for generating asbestos aerosols, but may be used with other dusts as well. Using this system, a steady state concentration (39.1 fibers/cc >5 m in length ± 6.2%) of asbestos aerosol was maintained in an inhalation chamber for five hours. In addition, FBG output concentration was easily adjusted and quickly equilibrated (within 10 minutes). The system provides a good technique for generating asbestos aerosols for day-long animal exposures.
