摘要：
Raccoons (Procyon lotor) are one of the most widespread and abundant mammals in North America. To evaluate the suitability of using raccoons as bioindicator species, we analyzed liver tissues (n = 32) collected from 2013 to 2015 for the presence of polybrominated diphenyl ethers (PBDEs) and Dechloranes. aPBDE concentrations ranged from 19.1 to 2125 ng/g lw (median = 98.0 ng/g lw) and did not differ between gender or age of raccoon. Dechloranes were detected in 38% of raccoons and ranged from 0.15 to 50.4 ng/g lw (median = 2.32 ng/g lw). The comparatively high PBDE concentrations, and presence of Dechloranes in the raccoons in our study suggest that biota in terrestrial habitats are still widely exposed to and susceptible to the bioaccumulation of current and emerging flame retardants.
