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 mgm3, and the respirable proportions were between 2.4 and 50.2.
Another study of spice mill workers reported inhalable dust concentrations of 1.0 to 29.9 mgm3 van der Walt et al. 2010. A study in a seasoning factory found median inhalable spice dust concentrations of 12 mgm3 in the packaging area range 3.9150 mgm3, 4.8 mgm3 in mixing range 0.916 mgm3, and 9 mgm3 in grinding
