The pneumoconiosis developing after inhalation of air-borne dusts in the work place depends on the relation between the value of particle deposition in the respiratory tract and the rate of particle clearance from sites of their deposition. For testing the deposition in humans an aerosol of paraffin oil was given to a cohort of healthy persons. The characteristic parameters of the aerosol had been defined. The concentration of particles in 5 channels were measured in both the inhaled and exhaled air samples using the particle counter ROYCO 225. The deposition fraction was calculated from the relation of particle amount in expired air to the amount in inhaled air in each distribution class. In this preliminary report the results comparable with the prediction mathematical curve are discussed.
在工作场所吸入空气中的粉尘后发生的尘肺病取决于呼吸道中颗粒沉积值与颗粒从沉积部位清除速率之间的关系。为了测试人体中的沉积情况，向一组健康人给予石蜡油气溶胶。已确定了该气溶胶的特征参数。使用颗粒计数器ROYCO 225测量吸入和呼出空气样本中5个通道的颗粒浓度。沉积分数是根据每个分布类别中呼出空气中颗粒量与吸入空气中颗粒量的关系计算得出的。在这份初步报告中，讨论了与预测数学曲线可比的结果。
