black lung

respiratory disorder, a type of pneumoconiosis caused by repeated inhalation of coal dust over a period of years. The disease gets its name from a distinctive blue-black marbling of the lung caused by accumulation of the dust. Georgius Agricola, a German mineralogist, first described lung disease in coal miners in the 16th century, and it is now widely recognized. It may be the best known occupational illness in the United States.
