2-methylanthraquinone as a marker of occupational exposure to teak wood dust in boatyards.
Ann. Occup. Hyg. 53(1) , 27-32, (2009) A new gas chromatographic/mass spectrometric (GC/MS) method was developed to detect 2-methylanthraquinone (2-MeA) in wood dust. 2-MeA is present in teak wood (a suspected human carcinogen) but not in oak, beech, mahogany, birch, ash or pine. The method involv... |
