Measurement and calculation of deposition of china dust in various portions of respiratory tract by exhalation partitioning (measured by CO/sub 2/ content) are discussed. Data on retention of various sized dusts in upper respiratory or alveolar regions were converted to percent deposition curves. Upper respiratory deposition decreased from approx. 75% at 5 ..mu..m to approx. 10% at 1.5 ..mu..m. Alveolar deposition peaked (approx. 55%) at 1 ..mu..m.
