Abstract Occupational exposures play a role in the onset of several chronic airway diseases. We investigated in a cross-sectional study lung function parameters and bronchial hyperresponsiveness to histamine in workers exposed to different airborne compounds. The study group totalled 546 male subjects of whom 1 14 were exposed to welding fumes 106 to solvents 107 to mineral dust 97 to organic dust and 123 without known exposure to airway irritants. A questionnaire was administered and spirometry and bronchial responsiveness to histamine were assessed by one observer in the morning before work to prevent effects of acute exposure. The mean SD age of the participants was 39.3 7.8 years with a mean duration of employment of 13.8 6.6 years. Both before and after adjustment for smoking status forced .
