• Description:
  Pulmonary function losses in the Vermont granite industry working force over an 8 year period were examined. Employees in the Vermont granite industry were offered spirometry to measure forced vital capacity (FVC) and forced expiratory capacity in 1 minute (FEV1), biennially from 1979 to 1987. In 1983, chest radiograms and a standardized symptom questionnaire was also administered. There were about 70 stone sheds and six quarries in the Vermont granite industry. Ambient dust levels in the stone sheds were measured using personal breathing zone samplers during 1983 to 1984. Longitudinal loss was estimated based on results for 711 workers who were tested at least three times. The mean concentration of dust between 1983 and 1984 was 601 micrograms per cubic meter, in which 10.81% was quartz. The annual average loss of FVC was 0.018 liter while the annual average loss of FEV1 was 0.030 liter. The FEV1 to FVC percent was 0.37%. These losses did not correlate with years employed in the granite industry. The authors conclude that annual average pulmonary fraction losses in Vermont granite workers were not accelerated by dust levels. [Description provided by NIOSH]
