| Abstract |
This study investigated the consequences of improvements in the workplace environment over six decades (1940-1996) among 3634 asbestos miners and millers with at least one year's exposure. Workers completed a respiratory symptoms questionnaire and were subjected to chest radiography and a spirometric evaluation. The study population was separated into three groups according to the period in which they worked between 1940 and 1996, during which time occupational hygiene was progressively improved and exposures controlled. Improvements were generally observed for lung symptoms, pleural anomalies and lung function among the more recently exposed groups, after correcting for smoking and latency. |
