Limited reports are available on polybrominated diphenyl ethers (PBDEs) in sharks. In this study, PBDEs were measured in dorsal muscles (n=105) from 13 shark species collected from offshore and coastal waters of Korea. The PBDE concentrations varied greatly not only among species but also within species of sharks. The major PBDE congeners detected in our samples were BDEs 47, 28, 99, 153, 100, and 154. Concentrations of PBDEs in sharks in this study were lower than those reported for previous studies. The high PBDE concentrations were found for aggressive shark species. Inter-species differences in the concentrations and accumulation profiles of PBDEs are explained by differences in feeding habits and sampling locations. Several contributing factors such as growth velocity, trophic level, and local contamination may affect the bioaccumulation of PBDEs in sharks. The present study provides baselines for the occurrence and accumulation status of PBDEs in various shark species.
关于鲨鱼体内多溴二苯醚（PBDEs）的报道有限。在本研究中，对从韩国近海和沿海水域采集的13种鲨鱼的背肌（n = 105）中的多溴二苯醚进行了测量。多溴二苯醚的浓度不仅在不同鲨鱼物种之间有很大差异，而且在同一物种内部也有很大差异。在我们的样本中检测到的主要多溴二苯醚同系物是BDEs 47、28、99、153、100和154。本研究中鲨鱼体内多溴二苯醚的浓度低于先前研究报道的浓度。在具有攻击性的鲨鱼物种中发现了高浓度的多溴二苯醚。多溴二苯醚浓度和积累模式的种间差异可以通过摄食习惯和采样地点的差异来解释。生长速度、营养级和局部污染等几个因素可能会影响多溴二苯醚在鲨鱼体内的生物积累。本研究为各种鲨鱼物种中多溴二苯醚的存在和积累状况提供了基线。
