Vermont granite workers' mortality study.

A cohort mortality study was conducted on Vermont granite workers, including all stone shed and quarry workers employed between 1950 and 1982; 5,414 workers were followed from 1950 through 1982 to determine the causes of mortality. Of these workers, 1,532 died during the study period. Because of the higher dust levels prevalent before 1940, the cohort was analyzed in two categories, workers first employed before and after 1940. Silicosis (primary and secondary), silicotuberculosis, and lung cancer accounted for 24.4 percent of the deaths, with silicosis (primary and secondary) alone accounting for approximately 8 percent of the deaths. With regard to lung cancer, 102 workers were classified as having lung cancer as the underlying cause of death, and 25 workers were classified as having lung cancer as an additional cause of death. Neoplasms of the lung, respiratory tract, and other organs were not found to be elevated, even in those workers with high quartz (14808607) exposure. The authors conclude that in this study quartz dust was not a significant factor in the induction of neoplasms.
