Abstract
Ventilatory functions, forced vital capacity (FVC), forced expiratory valume in one second (FEV 1.0) and forced mid expiratory flow (FEF25-75
) of the 476 workers who were exposed to tobacco dust from the Cigarette Factory No. (1), Yangon were tested. Total and respirable dust concentration were measured at different job areas. The total dust concentration ranged from 3.1 to 12.78 mgm/ m3 and respirable dust concentration ranged from 1.72 to 5.5 mgm ./ mg in the production site. A significant trend towards a decrease in FEV 1.0 values according to increasing dust exposure and work duration (p< 0.05) was found among the exposed famale workers. Thus in this study, dose-response relationship between the tobacco dust exposure and ventilatory function impairment was observed in female workers.
