- Details on inhalation exposure:
- GENERATION OF TEST ATMOSPHERE / CHAMBER DESCRIPTION
- Exposure apparatus: plexiglass exposure chamber
- Exposure chamber volume: 260-L
- Source and rate of air: rate of flow through the chamber was 20 L/min
- System of generating particulates/aerosols: The material was administered as an aerosol, which was generated by a six-jet Collision nebulizer (BGI Incorporated, Waltham, MA). The air was passed through a desicant prior to being passed through the test material.
- Method of particle size determination:
- Temperature: 72o F
TEST ATMOSPHERE
- Brief description of analytical method used: The average concentration of the aerosol over the one-hour exposure period was calculated to be 12.6 mg/L by differential weighing of the flask from which the aerosol was generated. The particle size (mass median diameter) of the aerosol of the test material was determined, to assure that the animals received a respirable dose, using an Andersen Sampler cascade impactor. The sampler was run for 5 minutes midway through the exposure. During sampling, air from the breathing zone of the animals was drawn through the cascade impactor at the rate of 1 ft3/min. The amount of aerosol impacting on each plate of the Andersen Sampler was determined by differential weighing. From these values the mass median diameter of the aerosol was calculated to be 0.48 microns and the concentration was calculated to be 0.10 mg/L. - Analytical verification of test atmosphere concentrations:
