Mapping carcinogen exposure across urban fire incident response arenas using passive silicone-based samplers

Carcinogens are emitted in significant quantities at fire scenes and are a major contributor in the increased cancer risk observed in firefighters when compared to the general population. A knowledge gap exists in the current understanding of the distribution of these toxic compounds within a locali...
