Contamination of firefighters' merino wool and mixed fibre sweater and hood undergarments with polycyclic aromatic hydrocarbons.
Background: Several authors have studied contamination of polycyclic aromatic hydrocarbons (PAHs) found on the outer gears of firefighters, but to our knowledge, none have investigated merino wool and mixed fibre undergarments used underneath the protective turnout gear. We therefore performed a comprehensive study regarding selected PAHs in pieces cut out from different areas of firefighter's sweaters and hood used in real fires and laundered after each use.
Method: Hoods (38) and sweaters (58) were donated by 3 fire departments and from these garments 558 pieces of fabric were cut out. Extracts of the fabric pieces were analysed by liquid chromatography with ultraviolet and fluorescence detection for 7 PAHs: anthracene, benzo[a]pyrene, chrysene, fluoranthene, naphthalene, phenanthrene, and pyrene. In addition, a small study was performed to examine the removal of PAHs from sweaters during laundry.
Results: Trace amounts of anthracene, benzo[a]pyrene, fluoranthene, and pyrene were detected both in merino wool and mixed fibre sweaters and hoods with highest concentrations for the hoods and lowest for the back of the sweaters. Highest concentration was found for the forehead position of the hoods. Significantly higher concentrations of PAHs were found in both hoods and sweaters containing the textile meta-aramid. Laundering reduced the amount of PAHs-in the sweaters but not completely.
Conclusion: Trace levels of benzo[a]pyrene and 3 other PAHs could be found in firefighters routine laundered undergarments. Cleaning reduced the PAH levels but not completely, and textiles with meta-aramid contained more PAHs than those without. Merino wool and mixed fibre undergarments are used in many countries and the results are valuable outside this study.

About the Journal
Annals of Work Exposures and Health is dedicated to presenting advances in exposure science supporting the recognition, quantification, and control of exposures at work, and epidemiological studies on their effects on human health and well-being. A key question we apply to submission is, "Is this paper going to help readers better understand, quantify, and control conditions at work that adversely or positively affect health and well-being?"
We are interested in high quality scientific research addressing:
the quantification of work exposures, including chemical, biological, physical, biomechanical, and psychosocial, and the elements of work organization giving rise to such exposures;
the relationship between these exposures and the acute and chronic health consequences for those exposed and their families and communities;
populations at special risk of work-related exposures including women, under-represented minorities, immigrants, and other vulnerable groups such as temporary, contingent and informal sector workers;
the effectiveness of interventions addressing exposure and risk including production technologies, work process engineering, and personal protective systems;
policies and management approaches to reduce risk and improve health and well-being among workers, their families or communities;
methodologies and mechanisms that underlie the quantification and/or control of exposure and risk.
There is heavy pressure on space in the journal, and the above interests mean that we do not usually publish papers that simply report local conditions without generalizable results. We are also unlikely to publish reports on human health and well-being without information on the work exposure characteristics giving rise to the effects. We particularly welcome contributions from scientists based in, or addressing conditions in, developing economies that fall within the above scope.
