Respiratory illness in asbestos contaminated sites: the role of environmental exposure
…Plaques had a significant effect on forced vital capacity in males. Pleural abnormalities were less prevalent in the general population exposed after 1976. The editorial authors argued that exposure categories should consider distance from fibre sources…
