Abstract

190 workers exposed to vegetable dusts (wood and fodder dust) have been submitted to ventilatory functional tests before and after work, on a Monday; meanwhile, the environmental concentrations of vegetable dusts were recorded. The results obtained show: there is a significant reduction of the ventilatory parameters in the subjects exposed to higher environmental concentrations; a higher reduction, particularly involving the larger airways, has been detected in workers exposed to fodder dusts of more than 5 microns in diameter; of the group of subjects exposed to wood dusts, there was a significant reduction of the maximum mid-expiratory flow only in those exposed to higher concentrations of dusts of less than 5 microns in diameter. The authors, according to the close relationship found between the environmental concentration of dusts and the percentage of subjects with significant bronchospastic reaction, believe that the present TLV for vegetable dusts has to be lowered.
