A study was undertaken to determine the effect of wool dust exposure on respiratory function in employees of a Croatian wool textile mill. Subjects in a group of 158 female and 58 male textile mill employees ranging in age from 20 to 57 years were given questionnaires regarding chronic respiratory symptoms, occupational history and smoking habits. Delivery employees not exposed to textile dusts were used as a control group. The wool mill workers were engaged in opening bales, and in operating carding, spinning and weaving machines. Ventilatory capacity was measured in subjects before and after a work shift on a Monday. Airborne dust samples were collected during an 8 hour work shift. Exposed textile workers had a significantly higher prevalence of respiratory symptoms than did control workers. Dyspnea, nasal catarrh and sinusitis were the most commonly reported symptoms. Hoarseness was reported by 58.3% of female and 32.2% of male wool workers. Significant across shift reductions were seen for ventilatory capacity. Mean total dust concentration measured 8.1mg/m3, with a respirable fraction of 1.72mg/m3. Based on the high dust concentration and the high incidence of respiratory symptoms seen in this study, the authors conclude that wool mills need to be better monitored and controlled to reduce occupational respiratory disease.
