✦ Synopsis

The tannin concentration of hard-and soft-wood dust was determined in dust powder and in samples on filters. It varied from 1.6 2 0.3 mg g-' ( 2 SD) for fir, which is a soft wood, to 80 2 30 mg g-' (& SD) for oak, which is a hard wood. The low detection limit of the spectrophotometric method (1.5 p g per sample) made the analysis possible with no interference from cellulose ester filters. In five woodworking shops the concentrations of the total dust varied from 0.2 to 20 mg m-', while those of tannins varied from 2 to 341 p g m-'. As hard woods l i e oak or mahogany have a higher tannin concentration than soft woods, tannin concentration analysis in wood dust can be used as an indicator of exposure to hard-wood dust.
