NIOSH testimony on coal workers pneumoconiosis by J. D. Miller, July 27, 1981
The testimony before the Subcommittee on Oversight of the House Committee on Ways and Means summarized the results of NIOSH research and medical surveillance on coal workers' pneumoconiosis and black lung. NIOSH has conducted both epidemiologic and laboratory research on respiratory diseases among coal miners. Coal workers' pneumoconiosis is a distinct disease characterized by the development of coal macules, coal nodules and progressive massive fibrosis which results from deposition of coal mine dust in the lung and the relation of the lung to that dust. Mortality studies showed clearly that nonmalignant respiratory disease and accidents were increased among coal miners. An increase of lung cancer has not been documented. The National Coal Workers' Health Surveillance Program, conducted by NIOSH, provided each new miner with an initial and periodic free medical examination. As the surveillance program relied only on the chest X-ray, it was necessary to rely on the National Study of Coal Workers' Pneumoconiosis to estimate the prevalence of bronchitis and persistent breathlessness and lung function impairment.
