||Symptoms, airway responsiveness, and exposure to dust in beech and oak wood workers
||Apr. 2000, Vol.57, No.4, p.268-273. 33 ref.
||To investigate the relationship between exposure to wood dust and respiratory symptoms and bronchial hyperresponsiveness, 114 male woodworkers from five furniture factories and 13 male unexposed controls were examined. Dust concentration was measured by personal sampling. Cumulative exposure to dust was calculated for each woodworker by multiplying the duration of the work by the intensity of exposure (years.mg/m3). Bronchial hyperresponsiveness was assessed by the methacholine challenge test. Subjects were labelled methacholine challenge positive if forced expiratory volume in 1 second (FEV1) fell by ≥20%. The median cumulative exposure to dust was 110 years.mg/m3. Overall, no declines in FEV1 and forced vital capacity (FVC) were found with increasing exposures. A dose-response relation was found between intensity of exposure on one hand, and sore throat and increased prevalence of positive methacholine challenge tests on the other hand.
