✦ Synopsis

Professional exposure to vegetable dusts affect the respiratory function of the exposed subjects. A previous survey conducted in an industrial flour-mill demonstrated a higher frequency of respiratory sympt, oms in workers compared to a control group. Ten subjects employed in a work site particularly exposed to dust were studied. Each subject answered a quest'ionnaire and performed on Mondays and Fridays, at the begenning and end of his work shift, a flow volume curve and an isocapnic hyperventilation test. The aerobiology of the professional environ. merit avas also measured. We noted: 1) in the flow volume curves: a drop in the FEV I during the Monday morning shift, a significant difference bet~veen the FEV1 (p<0.05) and the MMEFR 25-75 (p<0.05) measured at 6 am on Monday and Friday, and between the MMEFR 25-75 values obtained at 12 noon on Monday and Friday (p<0.05). 2) after dsocapnic hyperventilation, a signifi.cant drop in the MMEFR 25-75 at 6 am on Monday (p<0.01) and in the FEV, and MMEFR 25-75 at 12 noon on Mondays (p<0.05), a significant drop in the FEVI at 1 pm on Monday (p<0.01).
