Excerpt from Pulmonary Disease Among Miners in the Joplin District, Missouri: And Its Relation to Rock Dust in the Mines, a Preliminary Report That the inhalation of sharp particles of dust injuries the mucous membrane of the lungs, and in this way lessens the resistance of the lungs to pathologic germs, especially the bacilli of pulmonary tuberculosis, has been proved by investigations of morbidity among workmen in dusty trades and by study of the prevalence of lung diseases in South Africa and other foreign countries. The matter is one of deep public concerns, and attention has been called to it from time to time in publications of the Bureau of Mines. Until recently, however, the bureau has been unable from lack of necessary funds to prosecute investigations comparable with those that have been carried on abroad. Recently, with a view to affording some measure of relief through suggested educational work and through State legislation, the bureau has undertaken, in cooperation with the Bureau of the Public Health Service, preliminary investigation of the production of dust in mental mines in various parts of the United States and the relation of the prevalence of dust to silicosis, or miner's consumption, and pulmonary tuberculosis among miners. Passed Assistant Surgeon A. J. Lanza has been detailed to the Bureau of Mine and is now working in cooperation with Edwin Higgins, a mining engineer of the bureau, in making a survey of conditions in various metal-mining districts of the United States. The following report deals with the prevalence of tuberculosis among the miners of the Joplin district, Missouri. Reports on other districts will be published as investigations are completed.
