Factors influencing dust retention in the pulmonary parenchyma.
Ann NY Acad Sci 1972 Dec; 200(1):37-45
Some observations are presented suggesting that substantial individual differences exist in the effectiveness of particle deposition in the airways and consequently proportionate differences in the effective dose of inhaled coal dust that reaches the pulmonary parenchyma. The technique used to generate the aerosol involves the atomization of an aqueous colloid ferric oxide. Estimates are given of the range of alveolar deposition of coal and quartz dust by nose and mouth breathing.
