Determinants of Exposure to Inhalable Particulate, Wood Dust, Resin Acids, and Monoterpenes in a Lumber Mill Environment

摘要

In a lumber mill in the northern inland region of British Columbia, we measured inhalable particulate, resin acid, and monoterpene exposures, and estimated wood dust exposures. Potential determinants of exposure were documented concurrently, including weather conditions, tree species, wood conditions, jobs, tasks, equipment used, and certain control measures. Over 220 personal samples were taken for each contaminant. Geometric mean concentrations were 0.98 mg/m~3 for inhalable particulate, 0.49 mg/m~3 for estimated wood dust, 8.04 μg/m~3 for total resin acids, and 1.11 mg/m~3 for total monoterpenes.
