Efforts were made to complete the verification of the interpretations of the first round of medical examinations of coal workers as required in the Act. A preliminary study was initiated to assess the prevalence of coal workers pneumoconiosis (CWP) in surface coal mine workers and a total of 1,323 men at six mines was examined. The major emphasis of research in 1972 was directed to the NIOSH Appalachian Laboratory for Occupational Respiratory Diseases located in Morgantown, West Virginia. The program includes clinical and physiological investigations of cardiopulmonary function, pathological examinations of diseased lungs, investigations of the role of infectious disease in the development and progression of CWP, biochemical investigations to detect the earliest effects of CWP at the cellular level, and epidemiological studies to identify the various factors concerned in the production of disease and to quantify their effects. 收起
