Asbestos disease in sheet metal workers: II. Radiologic signs of asbestosis among active workers.
A review of chest x-rays of 707 currently employed New York metropolitan area sheet metal workers found that 29.3% of the workers with 20 years or more of union membership (a surrogate for years of exposure) had radiologic abnormalities characteristic of parenchymal and/or pleural asbestosis, with 18.6% having abnormalities characteristic of parenchymal asbestosis (International Labor Organization [ILO] classification 1/0 or higher) and 17.4% of pleural asbestosis. The prevalence of abnormalities characteristic of either parenchymal and/or pleural asbestosis in the group as a whole was 16.4%, with 10.9% exhibiting signs of parenchymal asbestosis and 9.2% of pleural asbestosis. There was a strong, statistically significant relationship between years in the trade and the prevalence of radiologic abnormalities. These findings underscore the need for medical surveillance of all asbestos-exposed construction workers, including retirees and workers who have had past exposure but who are no longer exposed.
