摘要：Graphical abstractDisplay OmittedHighlights•Silicone dog tags are a new configuration of personalized passive sampling device.•Silicone dog tags detected 18 PAHs not previously reported as firefighter exposures.•Firefighters have higher chemical exposures on– compared to off-duty.•Concentrations were more correlated to fire attack numbers than firefighter rank.•Silicone dog tags can provide quantitative exposure data on chemical mixtures.AbstractOccupational chemical hazards in the fire service are hypothesized to play a role in increased cancer risk, and reliable sampling technologies are necessary for conducting firefighter chemical exposure assessments. This study presents the military-style dog tag as a new configuration of silicone passive sampling device to sample individual firefighters’ exposures at one high and one low fire call volume department in the Kansas City, Missouri metropolitan area. The recruited firefighters (n = 56) wore separate dog tags to assess on– and off-duty exposures (ndogtags = 110), for a total of 30 24 h shifts. Using a 63 PAH method (GC–MS/MS), the tags detected 45 unique PAHs, of which 18 have not been previously reported as firefighting exposures. PAH concentrations were higher for on– compared to off-duty tags (0.25
