Health effects of respirable coal mine dust: coal workers' pneumoconiosis
Coal worker's pneumoconiosis is discussed. The nature of the disease is described; it is classified as either simple coal worker's pneumoconiosis or progressive, massive fibrosis (PMF). Simple coal worker's pneumoconiosis is not considered to cause clinical illness. Widespread scarring of the lungs, resulting shortness of breath, pulmonary hypertension and congestive heart failure may be caused by PMF. Chronic exposure to respirable dust from coal mines is the most significant variable associated with the development of coal worker's pneumoconiosis. Exposure-response models are described, and factors affecting exposure to various types of dust are identified. Data for the prevalence of the disease in USA are presented, and the incidence among US mineworkers is discussed. (38 refs.)
