To assess the effectiveness of current measures for protecting shipyard welders and caulker/burners (WCBs) from the respiratory effects of fumes.
Methods-Shipyard tradesmen born after 1953 (cohort 1), and 181 older men, subjects of a previous study (cohort 2), were assessed, then followed up after an average interval of 6-7 years.
The respiratory associations with shipyard trades were assessed cross sectionally and longitudinally and an estimate made of the likely effects of selection bias.
Cohort 1 composed 90% of the 462 eligible WCBs and 239 other tradesmen ; there were 31 exclusions.
At follow up 139 of 146 men still in the shipyard and 43% of those who had left were reassessed.
The lapses were mainly due to migration.
All members of cohort 2 were followed up for respiratory symptoms, were recorded, and indices reflecting all aspects of lung function were measured.
At the initial assessment and independent of smoking, trade as a WCB was associated with increased prevalences of chronic cough, phlegm, and wheeze, a reduced transfer factor, and an enhanced age related deterioration in peak expiratory flow (measured cross sectionally).
Continued work as a WCB was associated with enhanced deteriorarion in lung function despite some ameliorarion of respiratory symptoms.
The effects of fume on forced expiratory volume, flow-volume curvilinearity, mean transit time, and moment ratio were independent of and at least as large as those due to smoking.
