Harbour porpoises are one of the three cetacean species inhabiting the Black Sea. This is the first study to report on polybrominated diphenyl ethers (PBDEs) and naturally-produced compounds, methoxylated PBDEs (MeO-PBDEs) and polybrominated hexahydroxanthene derivatives (PBHDs), in tissues (kidney, brain, blubber, liver, muscle) of male harbour porpoises (11 adults, 9 juveniles) from the Black Sea. Lipid-normalized concentrations decreased from muscle>blubber>liver>kidney>brain for the sum of polychlorinated biphenyls (PCBs) and for the sum of PBDEs. Among the naturally-produced compounds, levels of PBHDs were higher than of MeO-PBDEs, with tri-BHD and 6-MeO-BDE 47 being the dominant compounds for both groups, respectively. Concentrations of naturally-produced compounds decreased from blubber to brain, similarly to the sum of DDT and metabolites (DDXs). Concentrations of DDXs were highest, followed by PCBs, HCB, PBHDs, PBDEs and MeO-PBDEs. Levels of PCBs and PBDEs in blubber were lower than concentrations reported for harbour porpoises from the North Sea, while concentrations of DDXs were higher.
港湾鼠海豚是栖息在黑海的三种鲸目动物之一。这是首次在黑海雄性港湾鼠海豚（11 只成体，9 只幼体）组织（肾脏、大脑、鲸脂、肝脏、肌肉）中报告多溴二苯醚（PBDEs）和天然产物，即甲氧基化多溴二苯醚（MeO-PBDEs）和多溴六氢对苯二甲酸酯衍生物（PBHDs）的研究。对于多氯联苯（PCBs）总和和 PBDEs 总和，脂类归一化浓度从肌肉>鲸脂>肝脏>肾脏>大脑降低。在天然产物中，PBHDs 的水平高于 MeO-PBDEs，对于这两组化合物，三-BHD 和 6-MeO-BDE 47 分别是主要化合物。与 DDT 和代谢物（DDXs）总和相似，天然产物的浓度从鲸脂到大脑降低。DDXs 的浓度最高，其次是 PCBs、HCB、PBHDs、PBDEs 和 MeO-PBDEs。与北海的港湾鼠海豚相比，鲸脂中的 PCBs 和 PBDEs 浓度较低，而 DDXs 浓度较高。
