A cross sectional study was conducted to determine the respiratory hazards of brass workers.
The study group was selected randomly.
The control group was selected from the general population matched for age by cluster sampling.
There was a total of 154 pairs for the final analysis.
A questionnaire was administered to determine the prevalence of respiratory symptoms.
Forced vital capacity (FVC), forced expiratory volume in the first second (FEV1.0), forced expiratory flow rate in the mid 50% of the FVC (FEF25% - 75%) and peak expiratory flow rate (PEFR) were measured.
Chest radiography was performed on those with 5 or more years of service.
Cough, phlegm, chronic bronchitis and dyspnoea were significantly higher among brass workers.
The ventilatory capacity was significantly lower in all the indicators except FVC.
Smoking had no significant effect and a dose response relationship could not be demonstrated after inclusion of age in the regression model.
Five point five per cent had evidence of septal lines while 6.4% had emphysema.
