A tracer technique for the behaviour of dusts in experimental animal lungs using an automatic air pollution reproducer and a film scintillation counter

Technologies for laboratory generation of dust from geological materials

“…Miller and Woodbury [40] modified a blender to generate dust from cattlefeedlot soil samples as part of a test of dust emissions under different environmental conditions. The "Dry Particulate Aerosol Generator" described by Ledbetter et al [41] used an air jet to blow particles off of commercial cotton string wound on standard fishing reels, while the "Automatic Air Pollution Reproducer" [42] was fashioned from laboratory flasks and agitators to supply dust to animals. The "Turntable Dust Feeder" [43] used a rotating cylinder to deliver dust to a turntable's groove where it was picked up by an adjustable aspirator.…”
