title: [Dust deposition and elimination in the lung of rats inhaling coal and coalstone dusts].
abstract: The deposition and elimination of dust particles from the lung are very important in the occurrence of pneumoconiosis. Two samples of coal mine dusts were examined for their deposition and elimination from the rat lung. In the present study the phagocytic activity of alveolar macrophages in the transport of inhaled dust particles was determined with the method of luminol enhanced chemiluminescence. Coalstone dust was cleared from the alveolar lumen via the tracheobronchial tree more quickly than coal dust.
