Studies were carried out to determine the pulmonary function changes occurring in Vermont granite industry workers and the prevalence of radiographic abnormalities. Of nearly 100 workers surveyed for radiographic abnormalities, only 28 were considered to have abnormal x-rays, and only seven of these had the rounded type of densities seen in early silicosis. For the pulmonary function study, two comparison groups were used. One was composed of a cross section of the Vermont highway maintenance workers without significant exposure to dusts or fumes and the other group contained employees of a high technology industry who worked in a clean environment but who had exposures to various chemicals and solvents. The subjects were tested semiannually from 1979 through 1987. Losses in pulmonary function were related to the initial values for forced vital capacity (FVC) or forced expiratory volume in 1 second (FEV 1.0), height, age, and smoking history. Losses of both FVC and FEV 1.0 were not correlated with years employed in the granite industry. Losses of pulmonary function were significantly smaller than those estimated earlier. The authors conclude that current dust levels in the Vermont granite industry do not accelerate pulmonary function loss.
