This study surveyed wood dust exposure levels and pulmonary hazards among wood mill workers. Dust concentrations as measured by six-stage cascade impactors were high in work areas of grinding and screening. Total dust concentrations for these dusty activities ranged from 4.4 to 22.4 mg/m3, and the respirable proportions were between 2.4% and 50.2%. The dust level in the sawing work was 2.9 mg/m3. Although symptoms of cough and phlegm were higher in smoking workers than in nonsmoking workers… CONTINUE READING
