Abstract |
To examine whether urinary methyl isobutyl ketone (MIBK) and methyl ethyl ketone (MEK) are useful markers of low-level occupational exposure to these solvents, 27 furniture-making workers (19 men and eight women) and 11 non-exposed controls (six men and five women) volunteered to participate in this study. Eight-hour time-weighted average (TWA) concentrations of solvent vapours in air were monitored by diffusive sampling. Urine samples collected at the end of the shift were subjected to gas chromatography analysis. The relationship between the solvent concentrations and the corresponding urinary levels was examined by simple as well as multiple regression analysis. Significant correlations were found for both MIBK and MEK. It is concluded that urinary concentrations are good markers of exposure to both solvents. |
