Methods Respiratory symptoms in 138 woodchip workers, 94 straw workers and 107 control workers from 85 heating- or combined heating and power plants were collected by questionnaire. Spirometry, metacholine provocation tests and skin prick tests were performed on 310 workers. The work area concentrations of 'total dust' (n=181), airborne endotoxin (n=179), cultivable Aspergillus fumigatus (n=373) and cultivable fungi (n=406) were measured at each plant. Personal exposure was calculated from the time spent on different tasks and average work area exposures. Results Median (range) average personal exposures in biofuel plants were 0.05 (0 to 0.33) mg/m(3) for 'total' dust and 3.5 (0 to 294) endotoxin units/m(3) for endotoxin. Fungi were cultivated from filters (straw plants) or slit samplers (woodchip plants); the average personal exposures were 5.230×10(3) (118 to 1.85×10(4)) and 1.03×10(3) (364 to 5.01×10(3)) colony-forming units/m(3) respectively.
