Epidemiologic investigation of respiratory effects related to environmental exposure to asbestos inside insulated buildings.
The respiratory effects of environmental pollution by asbestos inside university buildings were studied by comparing radiographic, clinical, and functional parameters among three groups of workers with different levels of exposure. Eight hundred and twenty-eight (828) people who worked for at least 15 yr in asbestos-insulated buildings and who were without known occupational exposure to asbestos (environmentally exposed group [EE]) were compared to a group of 252 workers with occupational exposure (occupationally exposed group [OE]), used as positive control; and to a group of 350 people with no known exposure to asbestos (nonexposed group [NE]), within the same university. After adjustment for confounding variables, no differences could be seen between groups EE and NE. Group OE exhibited a higher prevalence of pleural changes and lower lung functions than groups EE and NE.
