Certain wild animals represent excellent models, or sentinels, to address issues related to environmental pollution [1]. Wild trout present several biological characteristics, that position it as a suitable tool for monitoring polybrominated diphenyl ethers (PBDE) levels in freshwater environments [3]: 1-They are at top of the food web and have a wide geographic distribution; 2-They have lipid-rich tissues and pollutant concentration capacity [2]. 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 through a meta-analysis, 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 assessments.
