Certain wild animals represent excellent models, or sentinels, to address issues related to environmental pollution [1]. Wild trout present several biological characteristics (including being at top of the food web, having lipid-rich tissues, pollutant concentration capacity, and a wide geographic distribution [2]), that position it as a potentially suitable tool for monitoring polybrominated diphenyl ethers (PBDE) levels in freshwater environments [3]. Despite their benefits, PBDEs are considered a threat to environmental health due to their persistence, toxicity, bioaccumulation potential, and endocrine disruption [3]. The presence of lower brominated diphenyl ethers has been detected in wild trout collected worldwide [3]. Over the last 20 years, a large number of studies have been reported using wild trout for PBDE assessment in freshwater environments. This work summarizes this research field, and considers the implications of the reported data with the aim to explore the feasibility of wild trout as a sentinel species for PBDEs in environmental health assessments.
