Biomarker Studies of Firefighter Chemical Exposure
topic
Urinary biomarker studies measuring 1-hydroxypyrene, S-phenylmercapturic acid, and muconic acid excretion before and after fire suppression activities quantify firefighter PAH and benzene absorption during fire operations, demonstrating significant post-fire biomarker elevation indicating dermal and respiratory carcinogen absorption, with studies comparing biomarker response with and without gross decontamination providing direct evidence of decontamination effectiveness for reducing actual firefighter chemical body burden.
Role
Provides direct human evidence of carcinogen absorption during firefighting operations beyond epidemiological cancer incidence studies, with biomarker measurements giving immediate post-exposure chemical absorption data that validates the exposure pathway from contaminated clothing through skin to internal body burden, and with decontamination intervention biomarker studies providing the dose-response evidence that supports the effectiveness of specific contamination reduction measures in reducing actual firefighter carcinogen exposure.
