Residue levels and patterns of polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), their hydroxylated metabolites (OH-PCBs, OH-PBDEs), and methoxylated PBDEs (MeO-PBDEs) in the blood of various terrestrial mammals in Japan, including cats, raccoon dogs, dogs, masked palm civets, foxes, raccoons, badgers, and mongooses were determined. Tri- through penta-chlorinated OH-PCBs were predominant in cat blood, whereas hexa- through octa-chlorinated OH-PCBs were found in other species. High proportion of BDE209 was found in all species, suggesting exposure to municipal waste and soil containing higher levels of deca-BDE products. 6OH-/MeO-BDE47 and 2′OH-/MeO-BDE68 were dominant in all terrestrial mammals. This is first report on the detection of OH-/MeO-PBDEs in the blood of terrestrial mammals. High concentrations of OH-/MeO-PBDEs were found in cats, suggesting the intake of these compounds from seafood. Cats exhibited higher accumulation and specific patterns of OH-PCBs, OH-PBDEs, and MeO-PBDEs, they may be at a high risk from these metabolites. ► Analysis of organohalogen metabolites in the blood of Japanese terrestrial mammals. ► First study on analysis of OH-/MeO-PBDEs in terrestrial mammals. ► Cats showed specific residue pattern of OH-PCBs compare to other species. ► Metabolic capacities of PCBs in carnivore were higher than marine mammals. ► Marine natural occurrence OH-/MeO-PBDEs were found in terrestrial mammals. Cats showed specific residue pattern of OH-PCBs compare to other species and marine natural occurrence OH-/MeO-PBDEs were detected in terrestrial mammals.
