Previously, we demonstrated the military-style silicone dog tag as a personal passive sampling device for assessing polycyclic aromatic hydrocarbon exposures among structural firefighters. This follow-up analysis examined the pEDC exposures based on department call volume, duty shift, and questionnaire variables. Structural firefighters (n&amp;nbsp;=&amp;nbsp;56) were from one high and one low fire call volume department (Kansas City, MO metropolitan area) and wore separate dog tags while on- and off-duty (n&amp;nbsp;=&amp;nbsp;110). The targeted 1530 analyte semi-quantitative screening method was conducted using gas chromatography mass spectrometry (n&amp;nbsp;=&amp;nbsp;433). A total of 47 pEDCs were detected, and several less-frequently-detected pEDCs (&amp;lt;75%) were more commonly detected in off- compared to on-duty dog tags (conditional logistic regression). Of the 11 phthalates and fragrances detected most frequently (&amp;gt;75%), off-duty pEDC concentrations were strongly correlated (r = 0.31-0.82, p &amp;lt; 0.05), suggesting co-applications of phthalates and fragrances in consumer products. Questionnaire variables of &quot;regular use of conventional cleaning products&quot; and &quot;fireplace in the home&quot; were associated with select elevated pEDC concentrations by duty shift (paired t-test). This suggested researchers should include detailed questions about consumer product use and home environment when examining personal pEDC exposures.&lt;/p&gt;

This study presents the military-style dog tag as a new configuration of silicone passive sampling device to sample individual firefighters&#039; exposures at one high and one low fire call volume department in the Kansas City, Missouri metropolitan area. The recruited firefighters (n&amp;nbsp;=&amp;nbsp;56) wore separate dog tags to assess on- and off-duty exposures (n&amp;nbsp;=&amp;nbsp;110), for a total of 30 24&amp;nbsp;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&amp;nbsp;&amp;lt;&amp;nbsp;Cohen&#039;s d&amp;nbsp;≤&amp;nbsp;0.80) and for the high compared to the low fire call volume department (0.25&amp;nbsp;≤&amp;nbsp;d&amp;nbsp;&amp;lt;&amp;nbsp;0.70). Using a 1530 analyte screening method (GC-MS), di-n-butyl phthalate, diisobutyl phthalate, guaiacol, and DEET were commonly detected analytes. The number of fire attacks a firefighter participated in was more strongly correlated with PAH concentrations than firefighter rank or years in the fire service. This suggested that quantitative data should be employed for firefighter exposure assessments, rather than surrogate measures. Because several detected analytes are listed as possible carcinogens, future firefighter exposure studies should consider evaluating complex mixtures to assess individual health risks.&lt;/p&gt;
